5 Changes between 0.9.8b and 0.9.9 [xx XXX xxxx]
7 *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names.
8 Modify get_crl() to find a valid (unexpired) CRL if possible.
11 *) New function X509_CRL_match() to check if two CRLs are identical. Normally
12 this would be called X509_CRL_cmp() but that name is already used by
13 a function that just compares CRL issuer names. Cache several CRL
14 extensions in X509_CRL structure and cache CRLDP in X509.
17 *) Store a "canonical" representation of X509_NAME structure (ASN1 Name)
18 this maps equivalent X509_NAME structures into a consistent structure.
19 Name comparison can then be performed rapidly using memcmp().
22 *) Non-blocking OCSP request processing. Add -timeout option to ocsp
26 *) Allow digests to supply their own micalg string for S/MIME type using
27 the ctrl EVP_MD_CTRL_MICALG.
30 *) During PKCS7 signing pass the PKCS7 SignerInfo structure to the
31 EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN
32 ctrl. It can then customise the structure before and/or after signing
36 *) New function OBJ_add_sigid() to allow application defined signature OIDs
37 to be added to OpenSSLs internal tables. New function OBJ_sigid_free()
38 to free up any added signature OIDs.
41 *) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(),
42 EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal
43 digest and cipher tables. New options added to openssl utility:
44 list-message-digest-algorithms and list-cipher-algorithms.
47 *) In addition to the numerical (unsigned long) thread ID, provide
48 for a pointer (void *) thread ID. This helps accomodate systems
49 that do not provide an unsigned long thread ID. OpenSSL assumes
50 it is in the same thread iff both the numerical and the pointer
51 thread ID agree; so applications are just required to define one
52 of them appropriately (e.g., by using a pointer to a per-thread
53 memory object malloc()ed by the application for the pointer-type
54 thread ID). Exactly analoguous to the existing functions
56 void CRYPTO_set_id_callback(unsigned long (*func)(void));
57 unsigned long (*CRYPTO_get_id_callback(void))(void);
58 unsigned long CRYPTO_thread_id(void);
60 we now have additional functions
62 void CRYPTO_set_idptr_callback(void *(*func)(void));
63 void *(*CRYPTO_get_idptr_callback(void))(void);
64 void *CRYPTO_thread_idptr(void);
66 also in <openssl/crypto.h>. The default value for
67 CRYPTO_thread_idptr() if the application has not provided its own
71 *) Change the array representation of binary polynomials: the list
72 of degrees of non-zero coefficients is now terminated with -1.
73 Previously it was terminated with 0, which was also part of the
74 value; thus, the array representation was not applicable to
75 polynomials where t^0 has coefficient zero. This change makes
76 the array representation useful in a more general context.
79 *) Various modifications and fixes to SSL/TLS cipher string
80 handling. For ECC, the code now distinguishes between fixed ECDH
81 with RSA certificates on the one hand and with ECDSA certificates
82 on the other hand, since these are separate ciphersuites. The
83 unused code for Fortezza ciphersuites has been removed.
85 For consistency with EDH, ephemeral ECDH is now called "EECDH"
86 (not "ECDHE"). For consistency with the code for DH
87 certificates, use of ECDH certificates is now considered ECDH
88 authentication, not RSA or ECDSA authentication (the latter is
89 merely the CA's signing algorithm and not actively used in the
92 The temporary ciphersuite alias "ECCdraft" is no longer
93 available, and ECC ciphersuites are no longer excluded from "ALL"
94 and "DEFAULT". The following aliases now exist for RFC 4492
95 ciphersuites, most of these by analogy with the DH case:
97 kECDHr - ECDH cert, signed with RSA
98 kECDHe - ECDH cert, signed with ECDSA
99 kECDH - ECDH cert (signed with either RSA or ECDSA)
100 kEECDH - ephemeral ECDH
101 ECDH - ECDH cert or ephemeral ECDH
107 AECDH - anonymous ECDH
108 EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH")
112 *) Add additional S/MIME capabilities for AES and GOST ciphers if supported.
113 Use correct micalg parameters depending on digest(s) in signed message.
116 *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process
117 an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code.
120 *) Initial engine support for EVP_PKEY_METHOD. New functions to permit
121 an engine to register a method. Add ENGINE lookups for methods and
122 functional reference processing.
125 *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of
126 EVP_{Sign,Verify}* which allow an application to customise the signature
130 *) New -resign option to smime utility. This adds one or more signers
131 to an existing PKCS#7 signedData structure. Also -md option to use an
132 alternative message digest algorithm for signing.
135 *) Tidy up PKCS#7 routines and add new functions to make it easier to
136 create PKCS7 structures containing multiple signers. Update smime
137 application to support multiple signers.
140 *) New -macalg option to pkcs12 utility to allow setting of an alternative
144 *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC.
145 Reorganize PBE internals to lookup from a static table using NIDs,
146 add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl:
147 EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative
148 PRF which will be automatically used with PBES2.
151 *) Replace the algorithm specific calls to generate keys in "req" with the
155 *) Update PKCS#7 enveloped data routines to use new API. This is now
156 supported by any public key method supporting the encrypt operation. A
157 ctrl is added to allow the public key algorithm to examine or modify
158 the PKCS#7 RecipientInfo structure if it needs to: for RSA this is
162 *) Add a ctrl to asn1 method to allow a public key algorithm to express
163 a default digest type to use. In most cases this will be SHA1 but some
164 algorithms (such as GOST) need to specify an alternative digest. The
165 return value indicates how strong the prefernce is 1 means optional and
166 2 is mandatory (that is it is the only supported type). Modify
167 ASN1_item_sign() to accept a NULL digest argument to indicate it should
168 use the default md. Update openssl utilities to use the default digest
169 type for signing if it is not explicitly indicated.
172 *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New
173 EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant
174 signing method from the key type. This effectively removes the link
175 between digests and public key types.
178 *) Add an OID cross reference table and utility functions. Its purpose is to
179 translate between signature OIDs such as SHA1WithrsaEncryption and SHA1,
180 rsaEncryption. This will allow some of the algorithm specific hackery
181 needed to use the correct OID to be removed.
184 *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO
185 structures for PKCS7_sign(). They are now set up by the relevant public
189 *) Add provisional EC pkey method with support for ECDSA and ECDH.
192 *) Add support for key derivation (agreement) in the API, DH method and
196 *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support
197 public and private key formats. As a side effect these add additional
198 command line functionality not previously available: DSA signatures can be
199 generated and verified using pkeyutl and DH key support and generation in
204 [Oliver Tappe <zooey@hirschkaefer.de>]
206 *) New make target "install_html_docs" installs HTML renditions of the
208 [Oliver Tappe <zooey@hirschkaefer.de>]
210 *) New utility "genpkey" this is analagous to "genrsa" etc except it can
211 generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to
212 support key and parameter generation and add initial key generation
213 functionality for RSA.
216 *) Add functions for main EVP_PKEY_method operations. The undocumented
217 functions EVP_PKEY_{encrypt,decrypt} have been renamed to
218 EVP_PKEY_{encrypt,decrypt}_old.
221 *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public
222 key API, doesn't do much yet.
225 *) New function EVP_PKEY_asn1_get0_info() to retrieve information about
226 public key algorithms. New option to openssl utility:
227 "list-public-key-algorithms" to print out info.
230 *) Implement the Supported Elliptic Curves Extension for
231 ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
234 *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or
235 EVP_CIPHER structures to avoid later problems in EVP_cleanup().
238 *) New utilities pkey and pkeyparam. These are similar to algorithm specific
239 utilities such as rsa, dsa, dsaparam etc except they process any key
243 *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New
244 functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
245 EVP_PKEY_print_param() to print public key data from an EVP_PKEY
249 *) Initial support for pluggable public key ASN1.
250 De-spaghettify the public key ASN1 handling. Move public and private
251 key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate
252 algorithm specific handling to a single module within the relevant
253 algorithm directory. Add functions to allow (near) opaque processing
254 of public and private key structures.
257 *) Implement the Supported Point Formats Extension for
258 ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
261 *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members
262 for the psk identity [hint] and the psk callback functions to the
263 SSL_SESSION, SSL and SSL_CTX structure.
266 PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA,
270 SSL_CTX_use_psk_identity_hint
271 SSL_get_psk_identity_hint
273 SSL_use_psk_identity_hint
275 [Mika Kousa and Pasi Eronen of Nokia Corporation]
277 *) Add RFC 3161 compliant time stamp request creation, response generation
278 and response verification functionality.
279 [Zoltán Glózik <zglozik@opentsa.org>, The OpenTSA Project]
281 *) Add initial support for TLS extensions, specifically for the server_name
282 extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now
283 have new members for a host name. The SSL data structure has an
284 additional member SSL_CTX *initial_ctx so that new sessions can be
285 stored in that context to allow for session resumption, even after the
286 SSL has been switched to a new SSL_CTX in reaction to a client's
287 server_name extension.
289 New functions (subject to change):
292 SSL_get_servername_type()
295 New CTRL codes and macros (subject to change):
297 SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
298 - SSL_CTX_set_tlsext_servername_callback()
299 SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG
300 - SSL_CTX_set_tlsext_servername_arg()
301 SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_hostname()
303 openssl s_client has a new '-servername ...' option.
305 openssl s_server has new options '-servername_host ...', '-cert2 ...',
306 '-key2 ...', '-servername_fatal' (subject to change). This allows
307 testing the HostName extension for a specific single host name ('-cert'
308 and '-key' remain fallbacks for handshakes without HostName
309 negotiation). If the unrecogninzed_name alert has to be sent, this by
310 default is a warning; it becomes fatal with the '-servername_fatal'
313 [Peter Sylvester, Remy Allais, Christophe Renou]
315 *) Whirlpool hash implementation is added.
318 *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to
319 bn(64,32). Because of instruction set limitations it doesn't have
320 any negative impact on performance. This was done mostly in order
321 to make it possible to share assembler modules, such as bn_mul_mont
322 implementations, between 32- and 64-bit builds without hassle.
325 *) Move code previously exiled into file crypto/ec/ec2_smpt.c
326 to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP
330 *) New candidate for BIGNUM assembler implementation, bn_mul_mont,
331 dedicated Montgomery multiplication procedure, is introduced.
332 BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher
333 "64-bit" performance on certain 32-bit targets.
336 *) New option SSL_OP_NO_COMP to disable use of compression selectively
337 in SSL structures. New SSL ctrl to set maximum send fragment size.
338 Save memory by seeting the I/O buffer sizes dynamically instead of
339 using the maximum available value.
342 *) New option -V for 'openssl ciphers'. This prints the ciphersuite code
343 in addition to the text details.
346 *) Very, very preliminary EXPERIMENTAL support for printing of general
347 ASN1 structures. This currently produces rather ugly output and doesn't
348 handle several customised structures at all.
351 *) Integrated support for PVK file format and some related formats such
352 as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
353 these in the 'rsa' and 'dsa' utilities.
356 *) Support for PKCS#1 RSAPublicKey format on rsa utility command line.
359 *) Remove the ancient ASN1_METHOD code. This was only ever used in one
360 place for the (very old) "NETSCAPE" format certificates which are now
361 handled using new ASN1 code equivalents.
364 *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD
365 pointer and make the SSL_METHOD parameter in SSL_CTX_new,
366 SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'.
369 *) Modify CRL distribution points extension code to print out previously
370 unsupported fields. Enhance extension setting code to allow setting of
374 *) Add print and set support for Issuing Distribution Point CRL extension.
377 *) Change 'Configure' script to enable Camellia by default.
380 Changes between 0.9.8b and 0.9.8c [xx XXX xxxx]
382 *) Change the Unix randomness entropy gathering to use poll() when
383 possible instead of select(), since the latter has some
384 undesirable limitations.
385 [Darryl Miles via Richard Levitte and Bodo Moeller]
387 *) Disable "ECCdraft" ciphersuites more thoroughly. Now special
388 treatment in ssl/ssl_ciph.s makes sure that these ciphersuites
389 cannot be implicitly activated as part of, e.g., the "AES" alias.
390 However, please upgrade to OpenSSL 0.9.9[-dev] for
391 non-experimental use of the ECC ciphersuites to get TLS extension
392 support, which is required for curve and point format negotiation
393 to avoid potential handshake problems.
396 *) Disable rogue ciphersuites:
398 - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
399 - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
400 - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
402 The latter two were purportedly from
403 draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
406 Also deactive the remaining ciphersuites from
407 draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as
408 unofficial, and the ID has long expired.
411 *) Fix RSA blinding Heisenbug (problems sometimes occured on
412 dual-core machines) and other potential thread-safety issues.
415 *) Add the symmetric cipher Camellia (128-bit, 192-bit, 256-bit key
416 versions), which is now available for royalty-free use
417 (see http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html).
418 Also, add Camellia TLS ciphersuites from RFC 4132.
420 To minimize changes between patchlevels in the OpenSSL 0.9.8
421 series, Camellia remains excluded from compilation unless OpenSSL
422 is configured with 'enable-camellia'.
425 *) Disable the padding bug check when compression is in use. The padding
426 bug check assumes the first packet is of even length, this is not
427 necessarily true if compresssion is enabled and can result in false
428 positives causing handshake failure. The actual bug test is ancient
429 code so it is hoped that implementations will either have fixed it by
430 now or any which still have the bug do not support compression.
433 Changes between 0.9.8a and 0.9.8b [04 May 2006]
435 *) When applying a cipher rule check to see if string match is an explicit
436 cipher suite and only match that one cipher suite if it is.
439 *) Link in manifests for VC++ if needed.
440 [Austin Ziegler <halostatue@gmail.com>]
442 *) Update support for ECC-based TLS ciphersuites according to
443 draft-ietf-tls-ecc-12.txt with proposed changes (but without
444 TLS extensions, which are supported starting with the 0.9.9
445 branch, not in the OpenSSL 0.9.8 branch).
448 *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support
449 opaque EVP_CIPHER_CTX handling.
452 *) Fixes and enhancements to zlib compression code. We now only use
453 "zlib1.dll" and use the default __cdecl calling convention on Win32
454 to conform with the standards mentioned here:
455 http://www.zlib.net/DLL_FAQ.txt
456 Static zlib linking now works on Windows and the new --with-zlib-include
457 --with-zlib-lib options to Configure can be used to supply the location
458 of the headers and library. Gracefully handle case where zlib library
462 *) Several fixes and enhancements to the OID generation code. The old code
463 sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't
464 handle numbers larger than ULONG_MAX, truncated printing and had a
465 non standard OBJ_obj2txt() behaviour.
468 *) Add support for building of engines under engine/ as shared libraries
469 under VC++ build system.
472 *) Corrected the numerous bugs in the Win32 path splitter in DSO.
473 Hopefully, we will not see any false combination of paths any more.
476 Changes between 0.9.8 and 0.9.8a [11 Oct 2005]
478 *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
479 (part of SSL_OP_ALL). This option used to disable the
480 countermeasure against man-in-the-middle protocol-version
481 rollback in the SSL 2.0 server implementation, which is a bad
482 idea. (CVE-2005-2969)
484 [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
485 for Information Security, National Institute of Advanced Industrial
486 Science and Technology [AIST], Japan)]
488 *) Add two function to clear and return the verify parameter flags.
491 *) Keep cipherlists sorted in the source instead of sorting them at
492 runtime, thus removing the need for a lock.
495 *) Avoid some small subgroup attacks in Diffie-Hellman.
496 [Nick Mathewson and Ben Laurie]
498 *) Add functions for well-known primes.
501 *) Extended Windows CE support.
502 [Satoshi Nakamura and Andy Polyakov]
504 *) Initialize SSL_METHOD structures at compile time instead of during
505 runtime, thus removing the need for a lock.
508 *) Make PKCS7_decrypt() work even if no certificate is supplied by
509 attempting to decrypt each encrypted key in turn. Add support to
513 Changes between 0.9.7h and 0.9.8 [05 Jul 2005]
515 [NB: OpenSSL 0.9.7i and later 0.9.7 patch levels were released after
518 *) Add libcrypto.pc and libssl.pc for those who feel they need them.
521 *) Change CA.sh and CA.pl so they don't bundle the CSR and the private
522 key into the same file any more.
525 *) Add initial support for Win64, both IA64 and AMD64/x64 flavors.
528 *) Add -utf8 command line and config file option to 'ca'.
529 [Stefan <stf@udoma.org]
531 *) Removed the macro des_crypt(), as it seems to conflict with some
532 libraries. Use DES_crypt().
535 *) Correct naming of the 'chil' and '4758cca' ENGINEs. This
536 involves renaming the source and generated shared-libs for
537 both. The engines will accept the corrected or legacy ids
538 ('ncipher' and '4758_cca' respectively) when binding. NB,
539 this only applies when building 'shared'.
540 [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe]
542 *) Add attribute functions to EVP_PKEY structure. Modify
543 PKCS12_create() to recognize a CSP name attribute and
544 use it. Make -CSP option work again in pkcs12 utility.
547 *) Add new functionality to the bn blinding code:
548 - automatic re-creation of the BN_BLINDING parameters after
549 a fixed number of uses (currently 32)
550 - add new function for parameter creation
551 - introduce flags to control the update behaviour of the
552 BN_BLINDING parameters
553 - hide BN_BLINDING structure
554 Add a second BN_BLINDING slot to the RSA structure to improve
555 performance when a single RSA object is shared among several
559 *) Add support for DTLS.
560 [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]
562 *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
563 to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
566 *) Remove buggy and incompletet DH cert support from
567 ssl/ssl_rsa.c and ssl/s3_both.c
570 *) Use SHA-1 instead of MD5 as the default digest algorithm for
571 the apps/openssl applications.
574 *) Compile clean with "-Wall -Wmissing-prototypes
575 -Wstrict-prototypes -Wmissing-declarations -Werror". Currently
576 DEBUG_SAFESTACK must also be set.
579 *) Change ./Configure so that certain algorithms can be disabled by default.
580 The new counterpiece to "no-xxx" is "enable-xxx".
582 The patented RC5 and MDC2 algorithms will now be disabled unless
583 "enable-rc5" and "enable-mdc2", respectively, are specified.
585 (IDEA remains enabled despite being patented. This is because IDEA
586 is frequently required for interoperability, and there is no license
587 fee for non-commercial use. As before, "no-idea" can be used to
588 avoid this algorithm.)
592 *) Add processing of proxy certificates (see RFC 3820). This work was
593 sponsored by KTH (The Royal Institute of Technology in Stockholm) and
594 EGEE (Enabling Grids for E-science in Europe).
597 *) RC4 performance overhaul on modern architectures/implementations, such
598 as Intel P4, IA-64 and AMD64.
601 *) New utility extract-section.pl. This can be used specify an alternative
602 section number in a pod file instead of having to treat each file as
603 a separate case in Makefile. This can be done by adding two lines to the
606 =for comment openssl_section:XXX
608 The blank line is mandatory.
612 *) New arguments -certform, -keyform and -pass for s_client and s_server
613 to allow alternative format key and certificate files and passphrase
617 *) New structure X509_VERIFY_PARAM which combines current verify parameters,
618 update associated structures and add various utility functions.
620 Add new policy related verify parameters, include policy checking in
621 standard verify code. Enhance 'smime' application with extra parameters
622 to support policy checking and print out.
625 *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3
626 Nehemiah processors. These extensions support AES encryption in hardware
627 as well as RNG (though RNG support is currently disabled).
628 [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov]
630 *) Deprecate BN_[get|set]_params() functions (they were ignored internally).
633 *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented.
634 [Andy Polyakov and a number of other people]
636 *) Improved PowerPC platform support. Most notably BIGNUM assembler
637 implementation contributed by IBM.
638 [Suresh Chari, Peter Waltenberg, Andy Polyakov]
640 *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public
641 exponent rather than 'unsigned long'. There is a corresponding change to
642 the new 'rsa_keygen' element of the RSA_METHOD structure.
643 [Jelte Jansen, Geoff Thorpe]
645 *) Functionality for creating the initial serial number file is now
646 moved from CA.pl to the 'ca' utility with a new option -create_serial.
648 (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial
649 number file to 1, which is bound to cause problems. To avoid
650 the problems while respecting compatibility between different 0.9.7
651 patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in
652 CA.pl for serial number initialization. With the new release 0.9.8,
653 we can fix the problem directly in the 'ca' utility.)
656 *) Reduced header interdepencies by declaring more opaque objects in
657 ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
658 give fewer recursive includes, which could break lazy source code - so
659 this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
660 developers should define this symbol when building and using openssl to
661 ensure they track the recommended behaviour, interfaces, [etc], but
662 backwards-compatible behaviour prevails when this isn't defined.
665 *) New function X509_POLICY_NODE_print() which prints out policy nodes.
668 *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
669 This will generate a random key of the appropriate length based on the
670 cipher context. The EVP_CIPHER can provide its own random key generation
671 routine to support keys of a specific form. This is used in the des and
672 3des routines to generate a key of the correct parity. Update S/MIME
673 code to use new functions and hence generate correct parity DES keys.
674 Add EVP_CHECK_DES_KEY #define to return an error if the key is not
675 valid (weak or incorrect parity).
678 *) Add a local set of CRLs that can be used by X509_verify_cert() as well
679 as looking them up. This is useful when the verified structure may contain
680 CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
681 present unless the new PKCS7_NO_CRL flag is asserted.
684 *) Extend ASN1 oid configuration module. It now additionally accepts the
687 shortName = some long name, 1.2.3.4
690 *) Reimplemented the BN_CTX implementation. There is now no more static
691 limitation on the number of variables it can handle nor the depth of the
692 "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
693 information can now expand as required, and rather than having a single
694 static array of bignums, BN_CTX now uses a linked-list of such arrays
695 allowing it to expand on demand whilst maintaining the usefulness of
699 *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
700 to allow all RSA operations to function using a single BN_CTX.
703 *) Preliminary support for certificate policy evaluation and checking. This
704 is initially intended to pass the tests outlined in "Conformance Testing
705 of Relying Party Client Certificate Path Processing Logic" v1.07.
708 *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and
709 remained unused and not that useful. A variety of other little bignum
710 tweaks and fixes have also been made continuing on from the audit (see
714 *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with
715 associated ASN1, EVP and SSL functions and old ASN1 macros.
718 *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
719 and this should never fail. So the return value from the use of
720 BN_set_word() (which can fail due to needless expansion) is now deprecated;
721 if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro.
724 *) BN_CTX_get() should return zero-valued bignums, providing the same
725 initialised value as BN_new().
726 [Geoff Thorpe, suggested by Ulf Möller]
728 *) Support for inhibitAnyPolicy certificate extension.
731 *) An audit of the BIGNUM code is underway, for which debugging code is
732 enabled when BN_DEBUG is defined. This makes stricter enforcements on what
733 is considered valid when processing BIGNUMs, and causes execution to
734 assert() when a problem is discovered. If BN_DEBUG_RAND is defined,
735 further steps are taken to deliberately pollute unused data in BIGNUM
736 structures to try and expose faulty code further on. For now, openssl will
737 (in its default mode of operation) continue to tolerate the inconsistent
738 forms that it has tolerated in the past, but authors and packagers should
739 consider trying openssl and their own applications when compiled with
740 these debugging symbols defined. It will help highlight potential bugs in
741 their own code, and will improve the test coverage for OpenSSL itself. At
742 some point, these tighter rules will become openssl's default to improve
743 maintainability, though the assert()s and other overheads will remain only
744 in debugging configurations. See bn.h for more details.
745 [Geoff Thorpe, Nils Larsch, Ulf Möller]
747 *) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure
748 that can only be obtained through BN_CTX_new() (which implicitly
749 initialises it). The presence of this function only made it possible
750 to overwrite an existing structure (and cause memory leaks).
753 *) Because of the callback-based approach for implementing LHASH as a
754 template type, lh_insert() adds opaque objects to hash-tables and
755 lh_doall() or lh_doall_arg() are typically used with a destructor callback
756 to clean up those corresponding objects before destroying the hash table
757 (and losing the object pointers). So some over-zealous constifications in
758 LHASH have been relaxed so that lh_insert() does not take (nor store) the
759 objects as "const" and the lh_doall[_arg] callback wrappers are not
760 prototyped to have "const" restrictions on the object pointers they are
761 given (and so aren't required to cast them away any more).
764 *) The tmdiff.h API was so ugly and minimal that our own timing utility
765 (speed) prefers to use its own implementation. The two implementations
766 haven't been consolidated as yet (volunteers?) but the tmdiff API has had
767 its object type properly exposed (MS_TM) instead of casting to/from "char
768 *". This may still change yet if someone realises MS_TM and "ms_time_***"
769 aren't necessarily the greatest nomenclatures - but this is what was used
770 internally to the implementation so I've used that for now.
773 *) Ensure that deprecated functions do not get compiled when
774 OPENSSL_NO_DEPRECATED is defined. Some "openssl" subcommands and a few of
775 the self-tests were still using deprecated key-generation functions so
776 these have been updated also.
779 *) Reorganise PKCS#7 code to separate the digest location functionality
780 into PKCS7_find_digest(), digest addtion into PKCS7_bio_add_digest().
781 New function PKCS7_set_digest() to set the digest type for PKCS#7
782 digestedData type. Add additional code to correctly generate the
783 digestedData type and add support for this type in PKCS7 initialization
787 *) New function PKCS7_set0_type_other() this initializes a PKCS7
788 structure of type "other".
791 *) Fix prime generation loop in crypto/bn/bn_prime.pl by making
792 sure the loop does correctly stop and breaking ("division by zero")
793 modulus operations are not performed. The (pre-generated) prime
794 table crypto/bn/bn_prime.h was already correct, but it could not be
795 re-generated on some platforms because of the "division by zero"
796 situation in the script.
797 [Ralf S. Engelschall]
799 *) Update support for ECC-based TLS ciphersuites according to
800 draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with
801 SHA-1 now is only used for "small" curves (where the
802 representation of a field element takes up to 24 bytes); for
803 larger curves, the field element resulting from ECDH is directly
804 used as premaster secret.
805 [Douglas Stebila (Sun Microsystems Laboratories)]
807 *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2
808 curve secp160r1 to the tests.
809 [Douglas Stebila (Sun Microsystems Laboratories)]
811 *) Add the possibility to load symbols globally with DSO.
812 [Götz Babin-Ebell <babin-ebell@trustcenter.de> via Richard Levitte]
814 *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better
815 control of the error stack.
818 *) Add support for STORE in ENGINE.
821 *) Add the STORE type. The intention is to provide a common interface
822 to certificate and key stores, be they simple file-based stores, or
823 HSM-type store, or LDAP stores, or...
824 NOTE: The code is currently UNTESTED and isn't really used anywhere.
827 *) Add a generic structure called OPENSSL_ITEM. This can be used to
828 pass a list of arguments to any function as well as provide a way
829 for a function to pass data back to the caller.
832 *) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup()
833 works like BUF_strdup() but can be used to duplicate a portion of
834 a string. The copy gets NUL-terminated. BUF_memdup() duplicates
838 *) Add the function sk_find_ex() which works like sk_find(), but will
839 return an index to an element even if an exact match couldn't be
840 found. The index is guaranteed to point at the element where the
841 searched-for key would be inserted to preserve sorting order.
844 *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but
845 takes an extra flags argument for optional functionality. Currently,
846 the following flags are defined:
848 OBJ_BSEARCH_VALUE_ON_NOMATCH
849 This one gets OBJ_bsearch_ex() to return a pointer to the first
850 element where the comparing function returns a negative or zero
853 OBJ_BSEARCH_FIRST_VALUE_ON_MATCH
854 This one gets OBJ_bsearch_ex() to return a pointer to the first
855 element where the comparing function returns zero. This is useful
856 if there are more than one element where the comparing function
860 *) Make it possible to create self-signed certificates with 'openssl ca'
861 in such a way that the self-signed certificate becomes part of the
862 CA database and uses the same mechanisms for serial number generation
863 as all other certificate signing. The new flag '-selfsign' enables
864 this functionality. Adapt CA.sh and CA.pl.in.
867 *) Add functionality to check the public key of a certificate request
868 against a given private. This is useful to check that a certificate
869 request can be signed by that key (self-signing).
872 *) Make it possible to have multiple active certificates with the same
873 subject in the CA index file. This is done only if the keyword
874 'unique_subject' is set to 'no' in the main CA section (default
875 if 'CA_default') of the configuration file. The value is saved
876 with the database itself in a separate index attribute file,
877 named like the index file with '.attr' appended to the name.
880 *) Generate muti valued AVAs using '+' notation in config files for
884 *) Support for nameConstraints certificate extension.
887 *) Support for policyConstraints certificate extension.
890 *) Support for policyMappings certificate extension.
893 *) Make sure the default DSA_METHOD implementation only uses its
894 dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL,
895 and change its own handlers to be NULL so as to remove unnecessary
896 indirection. This lets alternative implementations fallback to the
897 default implementation more easily.
900 *) Support for directoryName in GeneralName related extensions
904 *) Make it possible to link applications using Makefile.shared.
905 Make that possible even when linking against static libraries!
908 *) Support for single pass processing for S/MIME signing. This now
909 means that S/MIME signing can be done from a pipe, in addition
910 cleartext signing (multipart/signed type) is effectively streaming
911 and the signed data does not need to be all held in memory.
913 This is done with a new flag PKCS7_STREAM. When this flag is set
914 PKCS7_sign() only initializes the PKCS7 structure and the actual signing
915 is done after the data is output (and digests calculated) in
919 *) Add full support for -rpath/-R, both in shared libraries and
920 applications, at least on the platforms where it's known how
924 *) In crypto/ec/ec_mult.c, implement fast point multiplication with
925 precomputation, based on wNAF splitting: EC_GROUP_precompute_mult()
926 will now compute a table of multiples of the generator that
927 makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul()
928 faster (notably in the case of a single point multiplication,
930 [Nils Larsch, Bodo Moeller]
932 *) IPv6 support for certificate extensions. The various extensions
933 which use the IP:a.b.c.d can now take IPv6 addresses using the
934 formats of RFC1884 2.2 . IPv6 addresses are now also displayed
938 *) Added an ENGINE that implements RSA by performing private key
939 exponentiations with the GMP library. The conversions to and from
940 GMP's mpz_t format aren't optimised nor are any montgomery forms
941 cached, and on x86 it appears OpenSSL's own performance has caught up.
942 However there are likely to be other architectures where GMP could
943 provide a boost. This ENGINE is not built in by default, but it can be
944 specified at Configure time and should be accompanied by the necessary
945 linker additions, eg;
946 ./config -DOPENSSL_USE_GMP -lgmp
949 *) "openssl engine" will not display ENGINE/DSO load failure errors when
950 testing availability of engines with "-t" - the old behaviour is
951 produced by increasing the feature's verbosity with "-tt".
954 *) ECDSA routines: under certain error conditions uninitialized BN objects
955 could be freed. Solution: make sure initialization is performed early
956 enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de>
960 *) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD
961 and DH_METHOD (eg. by ENGINE implementations) to override the normal
962 software implementations. For DSA and DH, parameter generation can
963 also be overriden by providing the appropriate method callbacks.
966 *) Change the "progress" mechanism used in key-generation and
967 primality testing to functions that take a new BN_GENCB pointer in
968 place of callback/argument pairs. The new API functions have "_ex"
969 postfixes and the older functions are reimplemented as wrappers for
970 the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide
971 declarations of the old functions to help (graceful) attempts to
972 migrate to the new functions. Also, the new key-generation API
973 functions operate on a caller-supplied key-structure and return
974 success/failure rather than returning a key or NULL - this is to
975 help make "keygen" another member function of RSA_METHOD etc.
977 Example for using the new callback interface:
979 int (*my_callback)(int a, int b, BN_GENCB *cb) = ...;
983 BN_GENCB_set(&my_cb, my_callback, my_arg);
985 return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb);
986 /* For the meaning of a, b in calls to my_callback(), see the
987 * documentation of the function that calls the callback.
988 * cb will point to my_cb; my_arg can be retrieved as cb->arg.
989 * my_callback should return 1 if it wants BN_is_prime_ex()
990 * to continue, or 0 to stop.
995 *) Change the ZLIB compression method to be stateful, and make it
996 available to TLS with the number defined in
997 draft-ietf-tls-compression-04.txt.
1000 *) Add the ASN.1 structures and functions for CertificatePair, which
1001 is defined as follows (according to X.509_4thEditionDraftV6.pdf):
1003 CertificatePair ::= SEQUENCE {
1004 forward [0] Certificate OPTIONAL,
1005 reverse [1] Certificate OPTIONAL,
1006 -- at least one of the pair shall be present -- }
1008 Also implement the PEM functions to read and write certificate
1009 pairs, and defined the PEM tag as "CERTIFICATE PAIR".
1011 This needed to be defined, mostly for the sake of the LDAP
1012 attribute crossCertificatePair, but may prove useful elsewhere as
1016 *) Make it possible to inhibit symlinking of shared libraries in
1017 Makefile.shared, for Cygwin's sake.
1020 *) Extend the BIGNUM API by creating a function
1021 void BN_set_negative(BIGNUM *a, int neg);
1022 and a macro that behave like
1023 int BN_is_negative(const BIGNUM *a);
1025 to avoid the need to access 'a->neg' directly in applications.
1028 *) Implement fast modular reduction for pseudo-Mersenne primes
1029 used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
1030 EC_GROUP_new_curve_GFp() will now automatically use this
1032 [Nils Larsch <nla@trustcenter.de>]
1034 *) Add new lock type (CRYPTO_LOCK_BN).
1037 *) Change the ENGINE framework to automatically load engines
1038 dynamically from specific directories unless they could be
1039 found to already be built in or loaded. Move all the
1040 current engines except for the cryptodev one to a new
1042 The engines in engines/ are built as shared libraries if
1043 the "shared" options was given to ./Configure or ./config.
1044 Otherwise, they are inserted in libcrypto.a.
1045 /usr/local/ssl/engines is the default directory for dynamic
1046 engines, but that can be overriden at configure time through
1047 the usual use of --prefix and/or --openssldir, and at run
1048 time with the environment variable OPENSSL_ENGINES.
1049 [Geoff Thorpe and Richard Levitte]
1051 *) Add Makefile.shared, a helper makefile to build shared
1052 libraries. Addapt Makefile.org.
1055 *) Add version info to Win32 DLLs.
1056 [Peter 'Luna' Runestig" <peter@runestig.com>]
1058 *) Add new 'medium level' PKCS#12 API. Certificates and keys
1059 can be added using this API to created arbitrary PKCS#12
1060 files while avoiding the low level API.
1062 New options to PKCS12_create(), key or cert can be NULL and
1063 will then be omitted from the output file. The encryption
1064 algorithm NIDs can be set to -1 for no encryption, the mac
1065 iteration count can be set to 0 to omit the mac.
1067 Enhance pkcs12 utility by making the -nokeys and -nocerts
1068 options work when creating a PKCS#12 file. New option -nomac
1069 to omit the mac, NONE can be set for an encryption algorithm.
1070 New code is modified to use the enhanced PKCS12_create()
1071 instead of the low level API.
1074 *) Extend ASN1 encoder to support indefinite length constructed
1075 encoding. This can output sequences tags and octet strings in
1076 this form. Modify pk7_asn1.c to support indefinite length
1077 encoding. This is experimental and needs additional code to
1078 be useful, such as an ASN1 bio and some enhanced streaming
1081 Extend template encode functionality so that tagging is passed
1082 down to the template encoder.
1085 *) Let 'openssl req' fail if an argument to '-newkey' is not
1086 recognized instead of using RSA as a default.
1089 *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
1090 As these are not official, they are not included in "ALL";
1091 the "ECCdraft" ciphersuite group alias can be used to select them.
1092 [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
1094 *) Add ECDH engine support.
1095 [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
1097 *) Add ECDH in new directory crypto/ecdh/.
1098 [Douglas Stebila (Sun Microsystems Laboratories)]
1100 *) Let BN_rand_range() abort with an error after 100 iterations
1101 without success (which indicates a broken PRNG).
1104 *) Change BN_mod_sqrt() so that it verifies that the input value
1105 is really the square of the return value. (Previously,
1106 BN_mod_sqrt would show GIGO behaviour.)
1109 *) Add named elliptic curves over binary fields from X9.62, SECG,
1110 and WAP/WTLS; add OIDs that were still missing.
1112 [Sheueling Chang Shantz and Douglas Stebila
1113 (Sun Microsystems Laboratories)]
1115 *) Extend the EC library for elliptic curves over binary fields
1116 (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
1119 EC_GF2m_simple_method
1123 EC_GROUP_new_curve_GF2m
1124 EC_GROUP_set_curve_GF2m
1125 EC_GROUP_get_curve_GF2m
1126 EC_POINT_set_affine_coordinates_GF2m
1127 EC_POINT_get_affine_coordinates_GF2m
1128 EC_POINT_set_compressed_coordinates_GF2m
1130 Point compression for binary fields is disabled by default for
1131 patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
1134 As binary polynomials are represented as BIGNUMs, various members
1135 of the EC_GROUP and EC_POINT data structures can be shared
1136 between the implementations for prime fields and binary fields;
1137 the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
1138 are essentially identical to their ..._GFp counterparts.
1139 (For simplicity, the '..._GFp' prefix has been dropped from
1140 various internal method names.)
1142 An internal 'field_div' method (similar to 'field_mul' and
1143 'field_sqr') has been added; this is used only for binary fields.
1145 [Sheueling Chang Shantz and Douglas Stebila
1146 (Sun Microsystems Laboratories)]
1148 *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
1149 through methods ('mul', 'precompute_mult').
1151 The generic implementations (now internally called 'ec_wNAF_mul'
1152 and 'ec_wNAF_precomputed_mult') remain the default if these
1153 methods are undefined.
1155 [Sheueling Chang Shantz and Douglas Stebila
1156 (Sun Microsystems Laboratories)]
1158 *) New function EC_GROUP_get_degree, which is defined through
1159 EC_METHOD. For curves over prime fields, this returns the bit
1160 length of the modulus.
1162 [Sheueling Chang Shantz and Douglas Stebila
1163 (Sun Microsystems Laboratories)]
1165 *) New functions EC_GROUP_dup, EC_POINT_dup.
1166 (These simply call ..._new and ..._copy).
1168 [Sheueling Chang Shantz and Douglas Stebila
1169 (Sun Microsystems Laboratories)]
1171 *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
1172 Polynomials are represented as BIGNUMs (where the sign bit is not
1173 used) in the following functions [macros]:
1176 BN_GF2m_sub [= BN_GF2m_add]
1177 BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
1178 BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
1179 BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
1181 BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
1182 BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
1183 BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
1184 BN_GF2m_cmp [= BN_ucmp]
1186 (Note that only the 'mod' functions are actually for fields GF(2^m).
1187 BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
1189 For some functions, an the irreducible polynomial defining a
1190 field can be given as an 'unsigned int[]' with strictly
1191 decreasing elements giving the indices of those bits that are set;
1192 i.e., p[] represents the polynomial
1193 f(t) = t^p[0] + t^p[1] + ... + t^p[k]
1195 p[0] > p[1] > ... > p[k] = 0.
1196 This applies to the following functions:
1201 BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
1202 BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
1204 BN_GF2m_mod_sqrt_arr
1205 BN_GF2m_mod_solve_quad_arr
1209 Conversion can be performed by the following functions:
1214 bntest.c has additional tests for binary polynomial arithmetic.
1216 Two implementations for BN_GF2m_mod_div() are available.
1217 The default algorithm simply uses BN_GF2m_mod_inv() and
1218 BN_GF2m_mod_mul(). The alternative algorithm is compiled in only
1219 if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
1220 copyright notice in crypto/bn/bn_gf2m.c before enabling it).
1222 [Sheueling Chang Shantz and Douglas Stebila
1223 (Sun Microsystems Laboratories)]
1225 *) Add new error code 'ERR_R_DISABLED' that can be used when some
1226 functionality is disabled at compile-time.
1227 [Douglas Stebila <douglas.stebila@sun.com>]
1229 *) Change default behaviour of 'openssl asn1parse' so that more
1230 information is visible when viewing, e.g., a certificate:
1232 Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
1233 mode the content of non-printable OCTET STRINGs is output in a
1234 style similar to INTEGERs, but with '[HEX DUMP]' prepended to
1235 avoid the appearance of a printable string.
1236 [Nils Larsch <nla@trustcenter.de>]
1238 *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
1240 EC_GROUP_set_asn1_flag()
1241 EC_GROUP_get_asn1_flag()
1242 EC_GROUP_set_point_conversion_form()
1243 EC_GROUP_get_point_conversion_form()
1244 These control ASN1 encoding details:
1245 - Curves (i.e., groups) are encoded explicitly unless asn1_flag
1246 has been set to OPENSSL_EC_NAMED_CURVE.
1247 - Points are encoded in uncompressed form by default; options for
1248 asn1_for are as for point2oct, namely
1249 POINT_CONVERSION_COMPRESSED
1250 POINT_CONVERSION_UNCOMPRESSED
1251 POINT_CONVERSION_HYBRID
1253 Also add 'seed' and 'seed_len' members to EC_GROUP with access
1256 EC_GROUP_get0_seed()
1257 EC_GROUP_get_seed_len()
1258 This is used only for ASN1 purposes (so far).
1259 [Nils Larsch <nla@trustcenter.de>]
1261 *) Add 'field_type' member to EC_METHOD, which holds the NID
1262 of the appropriate field type OID. The new function
1263 EC_METHOD_get_field_type() returns this value.
1264 [Nils Larsch <nla@trustcenter.de>]
1269 EC_POINT_point2hex()
1270 EC_POINT_hex2point()
1271 providing useful interfaces to EC_POINT_point2oct() and
1272 EC_POINT_oct2point().
1273 [Nils Larsch <nla@trustcenter.de>]
1275 *) Change internals of the EC library so that the functions
1276 EC_GROUP_set_generator()
1277 EC_GROUP_get_generator()
1278 EC_GROUP_get_order()
1279 EC_GROUP_get_cofactor()
1280 are implemented directly in crypto/ec/ec_lib.c and not dispatched
1281 to methods, which would lead to unnecessary code duplication when
1282 adding different types of curves.
1283 [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
1285 *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
1286 arithmetic, and such that modified wNAFs are generated
1287 (which avoid length expansion in many cases).
1290 *) Add a function EC_GROUP_check_discriminant() (defined via
1291 EC_METHOD) that verifies that the curve discriminant is non-zero.
1293 Add a function EC_GROUP_check() that makes some sanity tests
1294 on a EC_GROUP, its generator and order. This includes
1295 EC_GROUP_check_discriminant().
1296 [Nils Larsch <nla@trustcenter.de>]
1298 *) Add ECDSA in new directory crypto/ecdsa/.
1300 Add applications 'openssl ecparam' and 'openssl ecdsa'
1301 (these are based on 'openssl dsaparam' and 'openssl dsa').
1303 ECDSA support is also included in various other files across the
1304 library. Most notably,
1305 - 'openssl req' now has a '-newkey ecdsa:file' option;
1306 - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
1307 - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
1308 d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
1309 them suitable for ECDSA where domain parameters must be
1310 extracted before the specific public key;
1311 - ECDSA engine support has been added.
1312 [Nils Larsch <nla@trustcenter.de>]
1314 *) Include some named elliptic curves, and add OIDs from X9.62,
1315 SECG, and WAP/WTLS. Each curve can be obtained from the new
1317 EC_GROUP_new_by_curve_name(),
1318 and the list of available named curves can be obtained with
1319 EC_get_builtin_curves().
1320 Also add a 'curve_name' member to EC_GROUP objects, which can be
1322 EC_GROUP_set_curve_name()
1323 EC_GROUP_get_curve_name()
1324 [Nils Larsch <larsch@trustcenter.de, Bodo Moeller]
1326 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
1327 was actually never needed) and in BN_mul(). The removal in BN_mul()
1328 required a small change in bn_mul_part_recursive() and the addition
1329 of the functions bn_cmp_part_words(), bn_sub_part_words() and
1330 bn_add_part_words(), which do the same thing as bn_cmp_words(),
1331 bn_sub_words() and bn_add_words() except they take arrays with
1335 Changes between 0.9.7j and 0.9.7k [xx XXX xxxx]
1337 *) Change the Unix randomness entropy gathering to use poll() when
1338 possible instead of select(), since the latter has some
1339 undesirable limitations.
1340 [Darryl Miles via Richard Levitte and Bodo Moeller]
1342 *) Disable rogue ciphersuites:
1344 - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
1345 - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
1346 - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
1348 The latter two were purportedly from
1349 draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
1352 Also deactive the remaining ciphersuites from
1353 draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as
1354 unofficial, and the ID has long expired.
1357 *) Fix RSA blinding Heisenbug (problems sometimes occured on
1358 dual-core machines) and other potential thread-safety issues.
1361 Changes between 0.9.7i and 0.9.7j [04 May 2006]
1363 *) Adapt fipsld and the build system to link against the validated FIPS
1364 module in FIPS mode.
1367 *) Fixes for VC++ 2005 build under Windows.
1370 *) Add new Windows build target VC-32-GMAKE for VC++. This uses GNU make
1371 from a Windows bash shell such as MSYS. It is autodetected from the
1372 "config" script when run from a VC++ environment. Modify standard VC++
1373 build to use fipscanister.o from the GNU make build.
1376 Changes between 0.9.7h and 0.9.7i [14 Oct 2005]
1378 *) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS.
1379 The value now differs depending on if you build for FIPS or not.
1380 BEWARE! A program linked with a shared FIPSed libcrypto can't be
1381 safely run with a non-FIPSed libcrypto, as it may crash because of
1382 the difference induced by this change.
1385 Changes between 0.9.7g and 0.9.7h [11 Oct 2005]
1387 *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
1388 (part of SSL_OP_ALL). This option used to disable the
1389 countermeasure against man-in-the-middle protocol-version
1390 rollback in the SSL 2.0 server implementation, which is a bad
1391 idea. (CVE-2005-2969)
1393 [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
1394 for Information Security, National Institute of Advanced Industrial
1395 Science and Technology [AIST], Japan)]
1397 *) Minimal support for X9.31 signatures and PSS padding modes. This is
1398 mainly for FIPS compliance and not fully integrated at this stage.
1401 *) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform
1402 the exponentiation using a fixed-length exponent. (Otherwise,
1403 the information leaked through timing could expose the secret key
1404 after many signatures; cf. Bleichenbacher's attack on DSA with
1408 *) Make a new fixed-window mod_exp implementation the default for
1409 RSA, DSA, and DH private-key operations so that the sequence of
1410 squares and multiplies and the memory access pattern are
1411 independent of the particular secret key. This will mitigate
1412 cache-timing and potential related attacks.
1414 BN_mod_exp_mont_consttime() is the new exponentiation implementation,
1415 and this is automatically used by BN_mod_exp_mont() if the new flag
1416 BN_FLG_EXP_CONSTTIME is set for the exponent. RSA, DSA, and DH
1417 will use this BN flag for private exponents unless the flag
1418 RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or
1419 DH_FLAG_NO_EXP_CONSTTIME, respectively, is set.
1421 [Matthew D Wood (Intel Corp), with some changes by Bodo Moeller]
1423 *) Change the client implementation for SSLv23_method() and
1424 SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0
1425 Client Hello message format if the SSL_OP_NO_SSLv2 option is set.
1426 (Previously, the SSL 2.0 backwards compatible Client Hello
1427 message format would be used even with SSL_OP_NO_SSLv2.)
1430 *) Add support for smime-type MIME parameter in S/MIME messages which some
1434 *) New function BN_MONT_CTX_set_locked() to set montgomery parameters in
1435 a threadsafe manner. Modify rsa code to use new function and add calls
1436 to dsa and dh code (which had race conditions before).
1439 *) Include the fixed error library code in the C error file definitions
1440 instead of fixing them up at runtime. This keeps the error code
1441 structures constant.
1444 Changes between 0.9.7f and 0.9.7g [11 Apr 2005]
1446 [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after
1449 *) Fixes for newer kerberos headers. NB: the casts are needed because
1450 the 'length' field is signed on one version and unsigned on another
1451 with no (?) obvious way to tell the difference, without these VC++
1452 complains. Also the "definition" of FAR (blank) is no longer included
1453 nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up
1454 some needed definitions.
1457 *) Undo Cygwin change.
1460 *) Added support for proxy certificates according to RFC 3820.
1461 Because they may be a security thread to unaware applications,
1462 they must be explicitely allowed in run-time. See
1463 docs/HOWTO/proxy_certificates.txt for further information.
1466 Changes between 0.9.7e and 0.9.7f [22 Mar 2005]
1468 *) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating
1469 server and client random values. Previously
1470 (SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in
1471 less random data when sizeof(time_t) > 4 (some 64 bit platforms).
1473 This change has negligible security impact because:
1475 1. Server and client random values still have 24 bytes of pseudo random
1478 2. Server and client random values are sent in the clear in the initial
1481 3. The master secret is derived using the premaster secret (48 bytes in
1482 size for static RSA ciphersuites) as well as client server and random
1485 The OpenSSL team would like to thank the UK NISCC for bringing this issue
1488 [Stephen Henson, reported by UK NISCC]
1490 *) Use Windows randomness collection on Cygwin.
1493 *) Fix hang in EGD/PRNGD query when communication socket is closed
1494 prematurely by EGD/PRNGD.
1495 [Darren Tucker <dtucker@zip.com.au> via Lutz Jänicke, resolves #1014]
1497 *) Prompt for pass phrases when appropriate for PKCS12 input format.
1500 *) Back-port of selected performance improvements from development
1501 branch, as well as improved support for PowerPC platforms.
1504 *) Add lots of checks for memory allocation failure, error codes to indicate
1505 failure and freeing up memory if a failure occurs.
1506 [Nauticus Networks SSL Team <openssl@nauticusnet.com>, Steve Henson]
1508 *) Add new -passin argument to dgst.
1511 *) Perform some character comparisons of different types in X509_NAME_cmp:
1512 this is needed for some certificates that reencode DNs into UTF8Strings
1513 (in violation of RFC3280) and can't or wont issue name rollover
1517 *) Make an explicit check during certificate validation to see that
1518 the CA setting in each certificate on the chain is correct. As a
1519 side effect always do the following basic checks on extensions,
1520 not just when there's an associated purpose to the check:
1522 - if there is an unhandled critical extension (unless the user
1523 has chosen to ignore this fault)
1524 - if the path length has been exceeded (if one is set at all)
1525 - that certain extensions fit the associated purpose (if one has
1529 Changes between 0.9.7d and 0.9.7e [25 Oct 2004]
1531 *) Avoid a race condition when CRLs are checked in a multi threaded
1532 environment. This would happen due to the reordering of the revoked
1533 entries during signature checking and serial number lookup. Now the
1534 encoding is cached and the serial number sort performed under a lock.
1535 Add new STACK function sk_is_sorted().
1538 *) Add Delta CRL to the extension code.
1541 *) Various fixes to s3_pkt.c so alerts are sent properly.
1542 [David Holmes <d.holmes@f5.com>]
1544 *) Reduce the chances of duplicate issuer name and serial numbers (in
1545 violation of RFC3280) using the OpenSSL certificate creation utilities.
1546 This is done by creating a random 64 bit value for the initial serial
1547 number when a serial number file is created or when a self signed
1548 certificate is created using 'openssl req -x509'. The initial serial
1549 number file is created using 'openssl x509 -next_serial' in CA.pl
1550 rather than being initialized to 1.
1553 Changes between 0.9.7c and 0.9.7d [17 Mar 2004]
1555 *) Fix null-pointer assignment in do_change_cipher_spec() revealed
1556 by using the Codenomicon TLS Test Tool (CVE-2004-0079)
1557 [Joe Orton, Steve Henson]
1559 *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites
1561 [Joe Orton, Steve Henson]
1563 *) Make it possible to have multiple active certificates with the same
1564 subject in the CA index file. This is done only if the keyword
1565 'unique_subject' is set to 'no' in the main CA section (default
1566 if 'CA_default') of the configuration file. The value is saved
1567 with the database itself in a separate index attribute file,
1568 named like the index file with '.attr' appended to the name.
1571 *) X509 verify fixes. Disable broken certificate workarounds when
1572 X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if
1573 keyUsage extension present. Don't accept CRLs with unhandled critical
1574 extensions: since verify currently doesn't process CRL extensions this
1575 rejects a CRL with *any* critical extensions. Add new verify error codes
1579 *) When creating an OCSP nonce use an OCTET STRING inside the extnValue.
1580 A clarification of RFC2560 will require the use of OCTET STRINGs and
1581 some implementations cannot handle the current raw format. Since OpenSSL
1582 copies and compares OCSP nonces as opaque blobs without any attempt at
1583 parsing them this should not create any compatibility issues.
1586 *) New md flag EVP_MD_CTX_FLAG_REUSE this allows md_data to be reused when
1587 calling EVP_MD_CTX_copy_ex() to avoid calling OPENSSL_malloc(). Without
1588 this HMAC (and other) operations are several times slower than OpenSSL
1592 *) Print out GeneralizedTime and UTCTime in ASN1_STRING_print_ex().
1593 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
1595 *) Use the correct content when signing type "other".
1598 Changes between 0.9.7b and 0.9.7c [30 Sep 2003]
1600 *) Fix various bugs revealed by running the NISCC test suite:
1602 Stop out of bounds reads in the ASN1 code when presented with
1603 invalid tags (CVE-2003-0543 and CVE-2003-0544).
1605 Free up ASN1_TYPE correctly if ANY type is invalid (CVE-2003-0545).
1607 If verify callback ignores invalid public key errors don't try to check
1608 certificate signature with the NULL public key.
1612 *) New -ignore_err option in ocsp application to stop the server
1613 exiting on the first error in a request.
1616 *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
1617 if the server requested one: as stated in TLS 1.0 and SSL 3.0
1621 *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
1622 extra data after the compression methods not only for TLS 1.0
1623 but also for SSL 3.0 (as required by the specification).
1624 [Bodo Moeller; problem pointed out by Matthias Loepfe]
1626 *) Change X509_certificate_type() to mark the key as exported/exportable
1627 when it's 512 *bits* long, not 512 bytes.
1630 *) Change AES_cbc_encrypt() so it outputs exact multiple of
1631 blocks during encryption.
1634 *) Various fixes to base64 BIO and non blocking I/O. On write
1635 flushes were not handled properly if the BIO retried. On read
1636 data was not being buffered properly and had various logic bugs.
1637 This also affects blocking I/O when the data being decoded is a
1641 *) Various S/MIME bugfixes and compatibility changes:
1642 output correct application/pkcs7 MIME type if
1643 PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures.
1644 Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening
1645 of files as .eml work). Correctly handle very long lines in MIME
1649 Changes between 0.9.7a and 0.9.7b [10 Apr 2003]
1651 *) Countermeasure against the Klima-Pokorny-Rosa extension of
1652 Bleichbacher's attack on PKCS #1 v1.5 padding: treat
1653 a protocol version number mismatch like a decryption error
1654 in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
1657 *) Turn on RSA blinding by default in the default implementation
1658 to avoid a timing attack. Applications that don't want it can call
1659 RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
1660 They would be ill-advised to do so in most cases.
1661 [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
1663 *) Change RSA blinding code so that it works when the PRNG is not
1664 seeded (in this case, the secret RSA exponent is abused as
1665 an unpredictable seed -- if it is not unpredictable, there
1666 is no point in blinding anyway). Make RSA blinding thread-safe
1667 by remembering the creator's thread ID in rsa->blinding and
1668 having all other threads use local one-time blinding factors
1669 (this requires more computation than sharing rsa->blinding, but
1670 avoids excessive locking; and if an RSA object is not shared
1671 between threads, blinding will still be very fast).
1674 *) Fixed a typo bug that would cause ENGINE_set_default() to set an
1675 ENGINE as defaults for all supported algorithms irrespective of
1676 the 'flags' parameter. 'flags' is now honoured, so applications
1677 should make sure they are passing it correctly.
1680 *) Target "mingw" now allows native Windows code to be generated in
1681 the Cygwin environment as well as with the MinGW compiler.
1684 Changes between 0.9.7 and 0.9.7a [19 Feb 2003]
1686 *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
1687 via timing by performing a MAC computation even if incorrrect
1688 block cipher padding has been found. This is a countermeasure
1689 against active attacks where the attacker has to distinguish
1690 between bad padding and a MAC verification error. (CVE-2003-0078)
1692 [Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
1693 Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
1694 Martin Vuagnoux (EPFL, Ilion)]
1696 *) Make the no-err option work as intended. The intention with no-err
1697 is not to have the whole error stack handling routines removed from
1698 libcrypto, it's only intended to remove all the function name and
1699 reason texts, thereby removing some of the footprint that may not
1700 be interesting if those errors aren't displayed anyway.
1702 NOTE: it's still possible for any application or module to have it's
1703 own set of error texts inserted. The routines are there, just not
1704 used by default when no-err is given.
1707 *) Add support for FreeBSD on IA64.
1708 [dirk.meyer@dinoex.sub.org via Richard Levitte, resolves #454]
1710 *) Adjust DES_cbc_cksum() so it returns the same value as the MIT
1711 Kerberos function mit_des_cbc_cksum(). Before this change,
1712 the value returned by DES_cbc_cksum() was like the one from
1713 mit_des_cbc_cksum(), except the bytes were swapped.
1714 [Kevin Greaney <Kevin.Greaney@hp.com> and Richard Levitte]
1716 *) Allow an application to disable the automatic SSL chain building.
1717 Before this a rather primitive chain build was always performed in
1718 ssl3_output_cert_chain(): an application had no way to send the
1719 correct chain if the automatic operation produced an incorrect result.
1721 Now the chain builder is disabled if either:
1723 1. Extra certificates are added via SSL_CTX_add_extra_chain_cert().
1725 2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set.
1727 The reasoning behind this is that an application would not want the
1728 auto chain building to take place if extra chain certificates are
1729 present and it might also want a means of sending no additional
1730 certificates (for example the chain has two certificates and the
1734 *) Add the possibility to build without the ENGINE framework.
1735 [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
1737 *) Under Win32 gmtime() can return NULL: check return value in
1738 OPENSSL_gmtime(). Add error code for case where gmtime() fails.
1741 *) DSA routines: under certain error conditions uninitialized BN objects
1742 could be freed. Solution: make sure initialization is performed early
1743 enough. (Reported and fix supplied by Ivan D Nestlerode <nestler@MIT.EDU>,
1744 Nils Larsch <nla@trustcenter.de> via PR#459)
1747 *) Another fix for SSLv2 session ID handling: the session ID was incorrectly
1748 checked on reconnect on the client side, therefore session resumption
1749 could still fail with a "ssl session id is different" error. This
1750 behaviour is masked when SSL_OP_ALL is used due to
1751 SSL_OP_MICROSOFT_SESS_ID_BUG being set.
1752 Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
1753 followup to PR #377.
1756 *) IA-32 assembler support enhancements: unified ELF targets, support
1757 for SCO/Caldera platforms, fix for Cygwin shared build.
1760 *) Add support for FreeBSD on sparc64. As a consequence, support for
1761 FreeBSD on non-x86 processors is separate from x86 processors on
1762 the config script, much like the NetBSD support.

1785 seems that in spite of existing for more than a year, many application
1786 author have done nothing to provide the necessary callbacks, which
1787 means that this particular engine will not work properly anywhere.

1789 of usability, to give the hw_ncipher.c a static lock, which is part
1791 NOTE: This is for the 0.9.7 series ONLY. This hack will never
1792 appear in 0.9.8 or later. We EXPECT application authors to have
1793 dealt properly with this when 0.9.8 is released (unless we actually
1794 make such changes in the libcrypto locking code that changes will
1795 have to be made anyway).
1798 *) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content
1799 octets have been read, EOF or an error occurs. Without this change
1800 some truncated ASN1 structures will not produce an error.

1804 Still give the possibility to force the use of Heimdal, but with
1805 warnings and a request that patches get sent to openssl-dev.

1871 *) New OPENSSL_assert() macro (similar to assert(), but enabled
1873 [Ben Laurie (CHATS)]
1875 *) Eliminate unused copy of key in RC4.
1876 [Ben Laurie (CHATS)]
1878 *) Eliminate unused and incorrectly sized buffers for IV in pem.h.
1879 [Ben Laurie (CHATS)]
1881 *) Fix off-by-one error in EGD path.
1882 [Ben Laurie (CHATS)]
1884 *) If RANDFILE path is too long, ignore instead of truncating.
1885 [Ben Laurie (CHATS)]
1887 *) Eliminate unused and incorrectly sized X.509 structure
1889 [Ben Laurie (CHATS)]
1891 *) Eliminate unused and dangerous function knumber().
1892 [Ben Laurie (CHATS)]
1894 *) Eliminate unused and dangerous structure, KSSL_ERR.
1895 [Ben Laurie (CHATS)]
1897 *) Protect against overlong session ID context length in an encoded
1898 session object. Since these are local, this does not appear to be
1900 [Ben Laurie (CHATS)]
1902 *) Change from security patch (see 0.9.6e below) that did not affect
1903 the 0.9.6 release series:
1905 Remote buffer overflow in SSL3 protocol - an attacker could
1906 supply an oversized master key in Kerberos-enabled versions.
1908 [Ben Laurie (CHATS)]
1910 *) Change the SSL kerb5 codes to match RFC 2712.
1913 *) Make -nameopt work fully for req and add -reqopt switch.
1914 [Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
1916 *) The "block size" for block ciphers in CFB and OFB mode should be 1.
1917 [Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
1919 *) Make sure tests can be performed even if the corresponding algorithms
1920 have been removed entirely. This was also the last step to make
1921 OpenSSL compilable with DJGPP under all reasonable conditions.
1922 [Richard Levitte, Doug Kaufman <dkaufman@rahul.net>]
1924 *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT
1925 to allow version independent disabling of normally unselected ciphers,
1926 which may be activated as a side-effect of selecting a single cipher.
1928 (E.g., cipher list string "RSA" enables ciphersuites that are left
1929 out of "ALL" because they do not provide symmetric encryption.
1930 "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.)
1931 [Lutz Jaenicke, Bodo Moeller]
1933 *) Add appropriate support for separate platform-dependent build
1934 directories. The recommended way to make a platform-dependent
1935 build directory is the following (tested on Linux), maybe with
1938 # Place yourself outside of the OpenSSL source tree. In
1939 # this example, the environment variable OPENSSL_SOURCE
1940 # is assumed to contain the absolute OpenSSL source directory.
1941 mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
1942 cd objtree/"`uname -s`-`uname -r`-`uname -m`"
1943 (cd $OPENSSL_SOURCE; find . -type f) | while read F; do
1944 mkdir -p `dirname $F`
1945 ln -s $OPENSSL_SOURCE/$F $F
1948 To be absolutely sure not to disturb the source tree, a "make clean"
1949 is a good thing. If it isn't successfull, don't worry about it,
1950 it probably means the source directory is very clean.
1953 *) Make sure any ENGINE control commands make local copies of string
1954 pointers passed to them whenever necessary. Otherwise it is possible
1955 the caller may have overwritten (or deallocated) the original string
1956 data when a later ENGINE operation tries to use the stored values.
1957 [Götz Babin-Ebell <babinebell@trustcenter.de>]
1959 *) Improve diagnostics in file reading and command-line digests.
1960 [Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>]
1962 *) Add AES modes CFB and OFB to the object database. Correct an
1963 error in AES-CFB decryption.
1966 *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
1967 allows existing EVP_CIPHER_CTX structures to be reused after
1968 calling EVP_*Final(). This behaviour is used by encryption
1969 BIOs and some applications. This has the side effect that
1970 applications must explicitly clean up cipher contexts with
1971 EVP_CIPHER_CTX_cleanup() or they will leak memory.
1974 *) Check the values of dna and dnb in bn_mul_recursive before calling
1975 bn_mul_comba (a non zero value means the a or b arrays do not contain
1976 n2 elements) and fallback to bn_mul_normal if either is not zero.
1979 *) Fix escaping of non-ASCII characters when using the -subj option
1980 of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
1983 *) Make object definitions compliant to LDAP (RFC2256): SN is the short
1984 form for "surname", serialNumber has no short form.
1985 Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
1986 therefore remove "mail" short name for "internet 7".
1987 The OID for unique identifiers in X509 certificates is
1988 x500UniqueIdentifier, not uniqueIdentifier.
1989 Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>)
1992 *) Add an "init" command to the ENGINE config module and auto initialize
1993 ENGINEs. Without any "init" command the ENGINE will be initialized
1994 after all ctrl commands have been executed on it. If init=1 the
1995 ENGINE is initailized at that point (ctrls before that point are run
1996 on the uninitialized ENGINE and after on the initialized one). If
1997 init=0 then the ENGINE will not be iniatialized at all.
2000 *) Fix the 'app_verify_callback' interface so that the user-defined
2001 argument is actually passed to the callback: In the
2002 SSL_CTX_set_cert_verify_callback() prototype, the callback
2003 declaration has been changed from
2006 int (*cb)(X509_STORE_CTX *,void *);
2007 in ssl_verify_cert_chain (ssl/ssl_cert.c), the call
2008 i=s->ctx->app_verify_callback(&ctx)
2009 has been changed into
2010 i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg).
2012 To update applications using SSL_CTX_set_cert_verify_callback(),
2013 a dummy argument can be added to their callback functions.
2014 [D. K. Smetters <smetters@parc.xerox.com>]
2016 *) Added the '4758cca' ENGINE to support IBM 4758 cards.
2017 [Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe]
2019 *) Add and OPENSSL_LOAD_CONF define which will cause
2020 OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
2021 This allows older applications to transparently support certain
2022 OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.
2023 Two new functions OPENSSL_add_all_algorithms_noconf() which will never
2024 load the config file and OPENSSL_add_all_algorithms_conf() which will
2025 always load it have also been added.
2028 *) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
2029 Adjust NIDs and EVP layer.
2030 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
2032 *) Config modules support in openssl utility.
2034 Most commands now load modules from the config file,
2035 though in a few (such as version) this isn't done
2036 because it couldn't be used for anything.
2038 In the case of ca and req the config file used is
2039 the same as the utility itself: that is the -config
2040 command line option can be used to specify an
2044 *) Move default behaviour from OPENSSL_config(). If appname is NULL
2045 use "openssl_conf" if filename is NULL use default openssl config file.
2048 *) Add an argument to OPENSSL_config() to allow the use of an alternative
2049 config section name. Add a new flag to tolerate a missing config file
2050 and move code to CONF_modules_load_file().
2053 *) Support for crypto accelerator cards from Accelerated Encryption
2054 Processing, www.aep.ie. (Use engine 'aep')
2055 The support was copied from 0.9.6c [engine] and adapted/corrected
2056 to work with the new engine framework.
2057 [AEP Inc. and Richard Levitte]
2059 *) Support for SureWare crypto accelerator cards from Baltimore
2060 Technologies. (Use engine 'sureware')
2061 The support was copied from 0.9.6c [engine] and adapted
2062 to work with the new engine framework.
2065 *) Have the CHIL engine fork-safe (as defined by nCipher) and actually
2066 make the newer ENGINE framework commands for the CHIL engine work.
2067 [Toomas Kiisk <vix@cyber.ee> and Richard Levitte]
2069 *) Make it possible to produce shared libraries on ReliantUNIX.
2070 [Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte]
2072 *) Add the configuration target debug-linux-ppro.
2073 Make 'openssl rsa' use the general key loading routines
2074 implemented in apps.c, and make those routines able to
2075 handle the key format FORMAT_NETSCAPE and the variant
2077 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
2079 *) Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
2080 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
2082 *) Add -keyform to rsautl, and document -engine.
2083 [Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>]
2085 *) Change BIO_new_file (crypto/bio/bss_file.c) to use new
2086 BIO_R_NO_SUCH_FILE error code rather than the generic
2087 ERR_R_SYS_LIB error code if fopen() fails with ENOENT.
2090 *) Add new functions
2092 ERR_peek_last_error_line
2093 ERR_peek_last_error_line_data.
2094 These are similar to
2097 ERR_peek_error_line_data,
2098 but report on the latest error recorded rather than the first one
2099 still in the error queue.
2100 [Ben Laurie, Bodo Moeller]
2102 *) default_algorithms option in ENGINE config module. This allows things
2104 default_algorithms = ALL
2105 default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS
2108 *) Prelminary ENGINE config module.
2111 *) New experimental application configuration code.
2114 *) Change the AES code to follow the same name structure as all other
2115 symmetric ciphers, and behave the same way. Move everything to
2116 the directory crypto/aes, thereby obsoleting crypto/rijndael.
2117 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
2119 *) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c.
2120 [Ben Laurie and Theo de Raadt]
2122 *) Add option to output public keys in req command.
2123 [Massimiliano Pala madwolf@openca.org]
2125 *) Use wNAFs in EC_POINTs_mul() for improved efficiency
2126 (up to about 10% better than before for P-192 and P-224).
2129 *) New functions/macros
2131 SSL_CTX_set_msg_callback(ctx, cb)
2132 SSL_CTX_set_msg_callback_arg(ctx, arg)
2133 SSL_set_msg_callback(ssl, cb)
2134 SSL_set_msg_callback_arg(ssl, arg)
2136 to request calling a callback function
2138 void cb(int write_p, int version, int content_type,
2139 const void *buf, size_t len, SSL *ssl, void *arg)
2141 whenever a protocol message has been completely received
2142 (write_p == 0) or sent (write_p == 1). Here 'version' is the
2143 protocol version according to which the SSL library interprets
2144 the current protocol message (SSL2_VERSION, SSL3_VERSION, or
2145 TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or
2146 the content type as defined in the SSL 3.0/TLS 1.0 protocol
2147 specification (change_cipher_spec(20), alert(21), handshake(22)).
2148 'buf' and 'len' point to the actual message, 'ssl' to the
2149 SSL object, and 'arg' is the application-defined value set by
2150 SSL[_CTX]_set_msg_callback_arg().
2152 'openssl s_client' and 'openssl s_server' have new '-msg' options
2153 to enable a callback that displays all protocol messages.
2156 *) Change the shared library support so shared libraries are built as
2157 soon as the corresponding static library is finished, and thereby get
2158 openssl and the test programs linked against the shared library.
2159 This still only happens when the keyword "shard" has been given to
2160 the configuration scripts.
2162 NOTE: shared library support is still an experimental thing, and
2163 backward binary compatibility is still not guaranteed.
2164 ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte]
2166 *) Add support for Subject Information Access extension.
2167 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
2169 *) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero
2170 additional bytes when new memory had to be allocated, not just
2171 when reusing an existing buffer.
2174 *) New command line and configuration option 'utf8' for the req command.
2175 This allows field values to be specified as UTF8 strings.
2178 *) Add -multi and -mr options to "openssl speed" - giving multiple parallel
2179 runs for the former and machine-readable output for the latter.
2182 *) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion
2183 of the e-mail address in the DN (i.e., it will go into a certificate
2184 extension only). The new configuration file option 'email_in_dn = no'
2185 has the same effect.
2186 [Massimiliano Pala madwolf@openca.org]
2188 *) Change all functions with names starting with des_ to be starting
2189 with DES_ instead. Add wrappers that are compatible with libdes,
2190 but are named _ossl_old_des_*. Finally, add macros that map the
2191 des_* symbols to the corresponding _ossl_old_des_* if libdes
2192 compatibility is desired. If OpenSSL 0.9.6c compatibility is
2193 desired, the des_* symbols will be mapped to DES_*, with one
2196 Since we provide two compatibility mappings, the user needs to
2197 define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes
2198 compatibility is desired. The default (i.e., when that macro
2199 isn't defined) is OpenSSL 0.9.6c compatibility.
2201 There are also macros that enable and disable the support of old
2202 des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT
2203 and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those
2204 are defined, the default will apply: to support the old des routines.
2206 In either case, one must include openssl/des.h to get the correct
2207 definitions. Do not try to just include openssl/des_old.h, that
2210 NOTE: This is a major break of an old API into a new one. Software
2211 authors are encouraged to switch to the DES_ style functions. Some
2212 time in the future, des_old.h and the libdes compatibility functions
2213 will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the
2214 default), and then completely removed.
2217 *) Test for certificates which contain unsupported critical extensions.
2218 If such a certificate is found during a verify operation it is
2219 rejected by default: this behaviour can be overridden by either
2220 handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
2221 by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
2222 X509_supported_extension() has also been added which returns 1 if a
2223 particular extension is supported.
2226 *) Modify the behaviour of EVP cipher functions in similar way to digests
2227 to retain compatibility with existing code.
2230 *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain
2231 compatibility with existing code. In particular the 'ctx' parameter does
2232 not have to be to be initialized before the call to EVP_DigestInit() and
2233 it is tidied up after a call to EVP_DigestFinal(). New function
2234 EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
2235 EVP_MD_CTX_copy() changed to not require the destination to be
2236 initialized valid and new function EVP_MD_CTX_copy_ex() added which
2237 requires the destination to be valid.
2239 Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
2240 EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
2243 *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
2244 so that complete 'Handshake' protocol structures are kept in memory
2245 instead of overwriting 'msg_type' and 'length' with 'body' data.
2248 *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
2249 [Massimo Santin via Richard Levitte]
2251 *) Major restructuring to the underlying ENGINE code. This includes
2252 reduction of linker bloat, separation of pure "ENGINE" manipulation
2253 (initialisation, etc) from functionality dealing with implementations
2254 of specific crypto iterfaces. This change also introduces integrated
2255 support for symmetric ciphers and digest implementations - so ENGINEs
2256 can now accelerate these by providing EVP_CIPHER and EVP_MD
2257 implementations of their own. This is detailed in crypto/engine/README
2258 as it couldn't be adequately described here. However, there are a few
2259 API changes worth noting - some RSA, DSA, DH, and RAND functions that
2260 were changed in the original introduction of ENGINE code have now
2261 reverted back - the hooking from this code to ENGINE is now a good
2262 deal more passive and at run-time, operations deal directly with
2263 RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
2264 dereferencing through an ENGINE pointer any more. Also, the ENGINE
2265 functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
2266 they were not being used by the framework as there is no concept of a
2267 BIGNUM_METHOD and they could not be generalised to the new
2268 'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
2269 ENGINE_cpy() has been removed as it cannot be consistently defined in
2273 *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
2276 *) Change mkdef.pl to sort symbols that get the same entry number,
2277 and make sure the automatically generated functions ERR_load_*
2278 become part of libeay.num as well.
2281 *) New function SSL_renegotiate_pending(). This returns true once
2282 renegotiation has been requested (either SSL_renegotiate() call
2283 or HelloRequest/ClientHello receveived from the peer) and becomes
2284 false once a handshake has been completed.
2285 (For servers, SSL_renegotiate() followed by SSL_do_handshake()
2286 sends a HelloRequest, but does not ensure that a handshake takes
2287 place. SSL_renegotiate_pending() is useful for checking if the
2288 client has followed the request.)
2291 *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
2292 By default, clients may request session resumption even during
2293 renegotiation (if session ID contexts permit); with this option,
2294 session resumption is possible only in the first handshake.
2296 SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes
2297 more bits available for options that should not be part of
2298 SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION).
2301 *) Add some demos for certificate and certificate request creation.
2304 *) Make maximum certificate chain size accepted from the peer application
2305 settable (SSL*_get/set_max_cert_list()), as proposed by
2306 "Douglas E. Engert" <deengert@anl.gov>.
2309 *) Add support for shared libraries for Unixware-7
2310 (Boyd Lynn Gerber <gerberb@zenez.com>).
2313 *) Add a "destroy" handler to ENGINEs that allows structural cleanup to
2314 be done prior to destruction. Use this to unload error strings from
2315 ENGINEs that load their own error strings. NB: This adds two new API
2316 functions to "get" and "set" this destroy handler in an ENGINE.
2319 *) Alter all existing ENGINE implementations (except "openssl" and
2320 "openbsd") to dynamically instantiate their own error strings. This
2321 makes them more flexible to be built both as statically-linked ENGINEs
2322 and self-contained shared-libraries loadable via the "dynamic" ENGINE.
2323 Also, add stub code to each that makes building them as self-contained
2324 shared-libraries easier (see README.ENGINE).
2327 *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
2328 implementations into applications that are completely implemented in
2329 self-contained shared-libraries. The "dynamic" ENGINE exposes control
2330 commands that can be used to configure what shared-library to load and
2331 to control aspects of the way it is handled. Also, made an update to
2332 the README.ENGINE file that brings its information up-to-date and
2333 provides some information and instructions on the "dynamic" ENGINE
2334 (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
2337 *) Make it possible to unload ranges of ERR strings with a new
2338 "ERR_unload_strings" function.
2341 *) Add a copy() function to EVP_MD.
2344 *) Make EVP_MD routines take a context pointer instead of just the
2345 md_data void pointer.
2348 *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
2349 that the digest can only process a single chunk of data
2350 (typically because it is provided by a piece of
2351 hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
2352 is only going to provide a single chunk of data, and hence the
2353 framework needn't accumulate the data for oneshot drivers.
2356 *) As with "ERR", make it possible to replace the underlying "ex_data"
2357 functions. This change also alters the storage and management of global
2358 ex_data state - it's now all inside ex_data.c and all "class" code (eg.
2359 RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
2360 index counters. The API functions that use this state have been changed
2361 to take a "class_index" rather than pointers to the class's local STACK
2362 and counter, and there is now an API function to dynamically create new
2363 classes. This centralisation allows us to (a) plug a lot of the
2364 thread-safety problems that existed, and (b) makes it possible to clean
2365 up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
2366 such data would previously have always leaked in application code and
2367 workarounds were in place to make the memory debugging turn a blind eye
2368 to it. Application code that doesn't use this new function will still
2369 leak as before, but their memory debugging output will announce it now
2370 rather than letting it slide.
2372 Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
2373 induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
2374 has a return value to indicate success or failure.
2377 *) Make it possible to replace the underlying "ERR" functions such that the
2378 global state (2 LHASH tables and 2 locks) is only used by the "default"
2379 implementation. This change also adds two functions to "get" and "set"
2380 the implementation prior to it being automatically set the first time
2381 any other ERR function takes place. Ie. an application can call "get",
2382 pass the return value to a module it has just loaded, and that module
2383 can call its own "set" function using that value. This means the
2384 module's "ERR" operations will use (and modify) the error state in the
2385 application and not in its own statically linked copy of OpenSSL code.
2388 *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
2389 reference counts. This performs normal REF_PRINT/REF_CHECK macros on
2390 the operation, and provides a more encapsulated way for external code
2391 (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
2392 to use these functions rather than manually incrementing the counts.
2394 Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
2397 *) Add EVP test program.
2400 *) Add symmetric cipher support to ENGINE. Expect the API to change!
2403 *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
2404 X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
2405 X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
2406 These allow a CRL to be built without having to access X509_CRL fields
2407 directly. Modify 'ca' application to use new functions.
2410 *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
2411 bug workarounds. Rollback attack detection is a security feature.
2412 The problem will only arise on OpenSSL servers when TLSv1 is not
2413 available (sslv3_server_method() or SSL_OP_NO_TLSv1).
2414 Software authors not wanting to support TLSv1 will have special reasons
2415 for their choice and can explicitly enable this option.
2416 [Bodo Moeller, Lutz Jaenicke]
2418 *) Rationalise EVP so it can be extended: don't include a union of
2419 cipher/digest structures, add init/cleanup functions for EVP_MD_CTX
2420 (similar to those existing for EVP_CIPHER_CTX).
2425 EVP_MD_CTX_init(&md); /* new function call */
2426 EVP_DigestInit(&md, EVP_sha1());
2427 EVP_DigestUpdate(&md, in, len);
2428 EVP_DigestFinal(&md, out, NULL);
2429 EVP_MD_CTX_cleanup(&md); /* new function call */
2433 *) Make DES key schedule conform to the usual scheme, as well as
2434 correcting its structure. This means that calls to DES functions
2435 now have to pass a pointer to a des_key_schedule instead of a
2436 plain des_key_schedule (which was actually always a pointer
2439 des_key_schedule ks;
2441 des_set_key_checked(..., &ks);
2442 des_ncbc_encrypt(..., &ks, ...);
2444 (Note that a later change renames 'des_...' into 'DES_...'.)
2447 *) Initial reduction of linker bloat: the use of some functions, such as
2448 PEM causes large amounts of unused functions to be linked in due to
2449 poor organisation. For example pem_all.c contains every PEM function
2450 which has a knock on effect of linking in large amounts of (unused)
2451 ASN1 code. Grouping together similar functions and splitting unrelated
2452 functions prevents this.
2455 *) Cleanup of EVP macros.
2458 *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
2459 correct _ecb suffix.
2462 *) Add initial OCSP responder support to ocsp application. The
2463 revocation information is handled using the text based index
2464 use by the ca application. The responder can either handle
2465 requests generated internally, supplied in files (for example
2466 via a CGI script) or using an internal minimal server.
2469 *) Add configuration choices to get zlib compression for TLS.
2472 *) Changes to Kerberos SSL for RFC 2712 compliance:
2473 1. Implemented real KerberosWrapper, instead of just using
2474 KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
2475 2. Implemented optional authenticator field of KerberosWrapper.
2477 Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
2478 and authenticator structs; see crypto/krb5/.
2480 Generalized Kerberos calls to support multiple Kerberos libraries.
2481 [Vern Staats <staatsvr@asc.hpc.mil>,
2482 Jeffrey Altman <jaltman@columbia.edu>
2483 via Richard Levitte]
2485 *) Cause 'openssl speed' to use fully hard-coded DSA keys as it
2486 already does with RSA. testdsa.h now has 'priv_key/pub_key'
2487 values for each of the key sizes rather than having just
2488 parameters (and 'speed' generating keys each time).
2491 *) Speed up EVP routines.
2494 type 8 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes
2495 des-cbc 4408.85k 5560.51k 5778.46k 5862.20k 5825.16k

2509 *) Added the OS2-EMX target.
2510 ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
2512 *) Rewrite apps to use NCONF routines instead of the old CONF. New functions
2513 to support NCONF routines in extension code. New function CONF_set_nconf()
2514 to allow functions which take an NCONF to also handle the old LHASH
2515 structure: this means that the old CONF compatible routines can be
2516 retained (in particular wrt extensions) without having to duplicate the
2517 code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
2520 *) Enhance the general user interface with mechanisms for inner control
2521 and with possibilities to have yes/no kind of prompts.
2524 *) Change all calls to low level digest routines in the library and
2525 applications to use EVP. Add missing calls to HMAC_cleanup() and
2526 don't assume HMAC_CTX can be copied using memcpy().
2527 [Verdon Walker <VWalker@novell.com>, Steve Henson]
2529 *) Add the possibility to control engines through control names but with
2530 arbitrary arguments instead of just a string.
2531 Change the key loaders to take a UI_METHOD instead of a callback
2532 function pointer. NOTE: this breaks binary compatibility with earlier
2533 versions of OpenSSL [engine].
2534 Adapt the nCipher code for these new conditions and add a card insertion
2538 *) Enhance the general user interface with mechanisms to better support
2539 dialog box interfaces, application-defined prompts, the possibility
2540 to use defaults (for example default passwords from somewhere else)
2541 and interrupts/cancellations.
2544 *) Tidy up PKCS#12 attribute handling. Add support for the CSP name
2545 attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
2548 *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
2549 tidy up some unnecessarily weird code in 'sk_new()').
2550 [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
2552 *) Change the key loading routines for ENGINEs to use the same kind
2553 callback (pem_password_cb) as all other routines that need this
2557 *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
2558 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
2559 than this minimum value is recommended.
2562 *) New random seeder for OpenVMS, using the system process statistics
2563 that are easily reachable.
2566 *) Windows apparently can't transparently handle global
2567 variables defined in DLLs. Initialisations such as:
2569 const ASN1_ITEM *it = &ASN1_INTEGER_it;
2571 wont compile. This is used by the any applications that need to
2572 declare their own ASN1 modules. This was fixed by adding the option
2573 EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
2574 needed for static libraries under Win32.
2577 *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
2578 setting of purpose and trust fields. New X509_STORE trust and
2579 purpose functions and tidy up setting in other SSL functions.
2582 *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
2583 structure. These are inherited by X509_STORE_CTX when it is
2584 initialised. This allows various defaults to be set in the
2585 X509_STORE structure (such as flags for CRL checking and custom
2586 purpose or trust settings) for functions which only use X509_STORE_CTX
2587 internally such as S/MIME.
2589 Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
2590 trust settings if they are not set in X509_STORE. This allows X509_STORE
2591 purposes and trust (in S/MIME for example) to override any set by default.
2593 Add command line options for CRL checking to smime, s_client and s_server
2597 *) Initial CRL based revocation checking. If the CRL checking flag(s)
2598 are set then the CRL is looked up in the X509_STORE structure and
2599 its validity and signature checked, then if the certificate is found
2600 in the CRL the verify fails with a revoked error.
2602 Various new CRL related callbacks added to X509_STORE_CTX structure.
2604 Command line options added to 'verify' application to support this.
2606 This needs some additional work, such as being able to handle multiple
2607 CRLs with different times, extension based lookup (rather than just
2608 by subject name) and ultimately more complete V2 CRL extension
2612 *) Add a general user interface API (crypto/ui/). This is designed
2613 to replace things like des_read_password and friends (backward
2614 compatibility functions using this new API are provided).
2615 The purpose is to remove prompting functions from the DES code
2616 section as well as provide for prompting through dialog boxes in
2617 a window system and the like.
2620 *) Add "ex_data" support to ENGINE so implementations can add state at a
2621 per-structure level rather than having to store it globally.
2624 *) Make it possible for ENGINE structures to be copied when retrieved by
2625 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
2626 This causes the "original" ENGINE structure to act like a template,
2627 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
2628 operational state can be localised to each ENGINE structure, despite the
2629 fact they all share the same "methods". New ENGINE structures returned in
2630 this case have no functional references and the return value is the single
2631 structural reference. This matches the single structural reference returned
2632 by ENGINE_by_id() normally, when it is incremented on the pre-existing
2636 *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
2637 needs to match any other type at all we need to manually clear the
2641 *) Changes to the "openssl engine" utility to include;
2642 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
2643 about an ENGINE's available control commands.
2644 - executing control commands from command line arguments using the
2645 '-pre' and '-post' switches. '-post' is only used if '-t' is
2646 specified and the ENGINE is successfully initialised. The syntax for
2647 the individual commands are colon-separated, for example;
2648 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
2651 *) New dynamic control command support for ENGINEs. ENGINEs can now
2652 declare their own commands (numbers), names (strings), descriptions,
2653 and input types for run-time discovery by calling applications. A
2654 subset of these commands are implicitly classed as "executable"
2655 depending on their input type, and only these can be invoked through
2656 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
2657 can be based on user input, config files, etc). The distinction is
2658 that "executable" commands cannot return anything other than a boolean
2659 result and can only support numeric or string input, whereas some
2660 discoverable commands may only be for direct use through
2661 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
2662 pointers, or other custom uses. The "executable" commands are to
2663 support parameterisations of ENGINE behaviour that can be
2664 unambiguously defined by ENGINEs and used consistently across any
2665 OpenSSL-based application. Commands have been added to all the
2666 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
2667 control over shared-library paths without source code alterations.
2670 *) Changed all ENGINE implementations to dynamically allocate their
2671 ENGINEs rather than declaring them statically. Apart from this being
2672 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
2673 this also allows the implementations to compile without using the
2674 internal engine_int.h header.
2677 *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
2678 'const' value. Any code that should be able to modify a RAND_METHOD
2679 should already have non-const pointers to it (ie. they should only
2680 modify their own ones).
2683 *) Made a variety of little tweaks to the ENGINE code.
2684 - "atalla" and "ubsec" string definitions were moved from header files
2685 to C code. "nuron" string definitions were placed in variables
2686 rather than hard-coded - allowing parameterisation of these values
2687 later on via ctrl() commands.
2688 - Removed unused "#if 0"'d code.
2689 - Fixed engine list iteration code so it uses ENGINE_free() to release
2690 structural references.
2691 - Constified the RAND_METHOD element of ENGINE structures.
2692 - Constified various get/set functions as appropriate and added
2693 missing functions (including a catch-all ENGINE_cpy that duplicates
2694 all ENGINE values onto a new ENGINE except reference counts/state).
2695 - Removed NULL parameter checks in get/set functions. Setting a method
2696 or function to NULL is a way of cancelling out a previously set
2697 value. Passing a NULL ENGINE parameter is just plain stupid anyway
2698 and doesn't justify the extra error symbols and code.
2699 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
2700 flags from engine_int.h to engine.h.
2701 - Changed prototypes for ENGINE handler functions (init(), finish(),
2702 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
2705 *) Implement binary inversion algorithm for BN_mod_inverse in addition
2706 to the algorithm using long division. The binary algorithm can be
2707 used only if the modulus is odd. On 32-bit systems, it is faster
2708 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
2709 roughly 5-15% for 256-bit moduli), so we use it only for moduli
2710 up to 450 bits. In 64-bit environments, the binary algorithm
2711 appears to be advantageous for much longer moduli; here we use it
2712 for moduli up to 2048 bits.
2715 *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
2716 could not support the combine flag in choice fields.
2719 *) Add a 'copy_extensions' option to the 'ca' utility. This copies
2720 extensions from a certificate request to the certificate.
2723 *) Allow multiple 'certopt' and 'nameopt' options to be separated
2724 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
2725 file: this allows the display of the certificate about to be
2726 signed to be customised, to allow certain fields to be included
2727 or excluded and extension details. The old system didn't display
2728 multicharacter strings properly, omitted fields not in the policy
2729 and couldn't display additional details such as extensions.
2732 *) Function EC_POINTs_mul for multiple scalar multiplication
2733 of an arbitrary number of elliptic curve points
2734 \sum scalars[i]*points[i],
2735 optionally including the generator defined for the EC_GROUP:
2736 scalar*generator + \sum scalars[i]*points[i].
2738 EC_POINT_mul is a simple wrapper function for the typical case
2739 that the point list has just one item (besides the optional
2743 *) First EC_METHODs for curves over GF(p):
2745 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
2746 operations and provides various method functions that can also
2747 operate with faster implementations of modular arithmetic.
2749 EC_GFp_mont_method() reuses most functions that are part of
2750 EC_GFp_simple_method, but uses Montgomery arithmetic.
2752 [Bodo Moeller; point addition and point doubling
2753 implementation directly derived from source code provided by
2754 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
2756 *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
2757 crypto/ec/ec_lib.c):
2759 Curves are EC_GROUP objects (with an optional group generator)
2760 based on EC_METHODs that are built into the library.
2762 Points are EC_POINT objects based on EC_GROUP objects.
2764 Most of the framework would be able to handle curves over arbitrary
2765 finite fields, but as there are no obvious types for fields other
2766 than GF(p), some functions are limited to that for now.
2769 *) Add the -HTTP option to s_server. It is similar to -WWW, but requires
2770 that the file contains a complete HTTP response.
2773 *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
2774 change the def and num file printf format specifier from "%-40sXXX"
2775 to "%-39s XXX". The latter will always guarantee a space after the
2776 field while the former will cause them to run together if the field
2777 is 40 of more characters long.
2780 *) Constify the cipher and digest 'method' functions and structures
2781 and modify related functions to take constant EVP_MD and EVP_CIPHER
2785 *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
2786 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
2789 *) Modify EVP_Digest*() routines so they now return values. Although the
2790 internal software routines can never fail additional hardware versions
2794 *) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
2796 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
2797 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
2800 ERR_R_NESTED_ASN1_ERROR
2802 ERR_R_MISSING_ASN1_EOS
2803 were 4 .. 9, conflicting with
2804 ERR_LIB_RSA (= ERR_R_RSA_LIB)
2806 ERR_LIB_PEM (= ERR_R_PEM_LIB).
2807 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
2809 Add new error code 'ERR_R_INTERNAL_ERROR'.
2812 *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
2816 *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
2817 sets the subject name for a new request or supersedes the
2818 subject name in a given request. Formats that can be parsed are
2819 'CN=Some Name, OU=myOU, C=IT'
2821 'CN=Some Name/OU=myOU/C=IT'.
2823 Add options '-batch' and '-verbose' to 'openssl req'.
2824 [Massimiliano Pala <madwolf@hackmasters.net>]
2826 *) Introduce the possibility to access global variables through
2827 functions on platform were that's the best way to handle exporting
2828 global variables in shared libraries. To enable this functionality,
2829 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
2830 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
2831 is normally done by Configure or something similar).
2833 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
2834 in the source file (foo.c) like this:
2836 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
2837 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
2839 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
2840 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
2842 OPENSSL_DECLARE_GLOBAL(int,foo);
2843 #define foo OPENSSL_GLOBAL_REF(foo)
2844 OPENSSL_DECLARE_GLOBAL(double,bar);
2845 #define bar OPENSSL_GLOBAL_REF(bar)
2847 The #defines are very important, and therefore so is including the
2848 header file everywhere where the defined globals are used.
2850 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
2851 of ASN.1 items, but that structure is a bit different.
2853 The largest change is in util/mkdef.pl which has been enhanced with
2854 better and easier to understand logic to choose which symbols should
2855 go into the Windows .def files as well as a number of fixes and code
2856 cleanup (among others, algorithm keywords are now sorted
2857 lexicographically to avoid constant rewrites).
2860 *) In BN_div() keep a copy of the sign of 'num' before writing the
2861 result to 'rm' because if rm==num the value will be overwritten
2862 and produce the wrong result if 'num' is negative: this caused
2863 problems with BN_mod() and BN_nnmod().
2866 *) Function OCSP_request_verify(). This checks the signature on an
2867 OCSP request and verifies the signer certificate. The signer
2868 certificate is just checked for a generic purpose and OCSP request
2872 *) Add OCSP_check_validity() function to check the validity of OCSP
2873 responses. OCSP responses are prepared in real time and may only
2874 be a few seconds old. Simply checking that the current time lies
2875 between thisUpdate and nextUpdate max reject otherwise valid responses
2876 caused by either OCSP responder or client clock inaccuracy. Instead
2877 we allow thisUpdate and nextUpdate to fall within a certain period of
2878 the current time. The age of the response can also optionally be
2879 checked. Two new options -validity_period and -status_age added to
2883 *) If signature or public key algorithm is unrecognized print out its
2884 OID rather that just UNKNOWN.
2887 *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
2888 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
2889 ID to be generated from the issuer certificate alone which can then be
2890 passed to OCSP_id_issuer_cmp().
2893 *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
2894 ASN1 modules to export functions returning ASN1_ITEM pointers
2895 instead of the ASN1_ITEM structures themselves. This adds several
2896 new macros which allow the underlying ASN1 function/structure to
2897 be accessed transparently. As a result code should not use ASN1_ITEM
2898 references directly (such as &X509_it) but instead use the relevant
2899 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
2900 use of the new ASN1 code on platforms where exporting structures
2901 is problematical (for example in shared libraries) but exporting
2902 functions returning pointers to structures is not.
2905 *) Add support for overriding the generation of SSL/TLS session IDs.
2906 These callbacks can be registered either in an SSL_CTX or per SSL.
2907 The purpose of this is to allow applications to control, if they wish,
2908 the arbitrary values chosen for use as session IDs, particularly as it
2909 can be useful for session caching in multiple-server environments. A
2910 command-line switch for testing this (and any client code that wishes
2911 to use such a feature) has been added to "s_server".
2912 [Geoff Thorpe, Lutz Jaenicke]
2914 *) Modify mkdef.pl to recognise and parse preprocessor conditionals
2915 of the form '#if defined(...) || defined(...) || ...' and
2916 '#if !defined(...) && !defined(...) && ...'. This also avoids
2917 the growing number of special cases it was previously handling.
2920 *) Make all configuration macros available for application by making
2921 sure they are available in opensslconf.h, by giving them names starting
2922 with "OPENSSL_" to avoid conflicts with other packages and by making
2923 sure e_os2.h will cover all platform-specific cases together with
2925 Additionally, it is now possible to define configuration/platform-
2926 specific names (called "system identities"). In the C code, these
2927 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
2928 macro with the name beginning with "OPENSSL_SYS_", which is determined
2929 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
2933 *) New option -set_serial to 'req' and 'x509' this allows the serial
2934 number to use to be specified on the command line. Previously self
2935 signed certificates were hard coded with serial number 0 and the
2936 CA options of 'x509' had to use a serial number in a file which was
2940 *) New options to 'ca' utility to support V2 CRL entry extensions.
2941 Currently CRL reason, invalidity date and hold instruction are
2942 supported. Add new CRL extensions to V3 code and some new objects.
2945 *) New function EVP_CIPHER_CTX_set_padding() this is used to
2946 disable standard block padding (aka PKCS#5 padding) in the EVP
2947 API, which was previously mandatory. This means that the data is
2948 not padded in any way and so the total length much be a multiple
2949 of the block size, otherwise an error occurs.
2952 *) Initial (incomplete) OCSP SSL support.
2955 *) New function OCSP_parse_url(). This splits up a URL into its host,
2956 port and path components: primarily to parse OCSP URLs. New -url
2957 option to ocsp utility.
2960 *) New nonce behavior. The return value of OCSP_check_nonce() now
2961 reflects the various checks performed. Applications can decide
2962 whether to tolerate certain situations such as an absent nonce
2963 in a response when one was present in a request: the ocsp application
2964 just prints out a warning. New function OCSP_add1_basic_nonce()
2965 this is to allow responders to include a nonce in a response even if
2966 the request is nonce-less.
2969 *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
2970 skipped when using openssl x509 multiple times on a single input file,
2971 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
2974 *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
2975 set string type: to handle setting ASN1_TIME structures. Fix ca
2976 utility to correctly initialize revocation date of CRLs.
2979 *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
2980 the clients preferred ciphersuites and rather use its own preferences.
2981 Should help to work around M$ SGC (Server Gated Cryptography) bug in
2982 Internet Explorer by ensuring unchanged hash method during stepup.
2983 (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
2986 *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
2987 to aes and add a new 'exist' option to print out symbols that don't
2991 *) Additional options to ocsp utility to allow flags to be set and
2992 additional certificates supplied.
2995 *) Add the option -VAfile to 'openssl ocsp', so the user can give the
2996 OCSP client a number of certificate to only verify the response
3000 *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
3001 handle the new API. Currently only ECB, CBC modes supported. Add new
3004 Add TLS AES ciphersuites as described in RFC3268, "Advanced
3005 Encryption Standard (AES) Ciphersuites for Transport Layer
3006 Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were
3007 not enabled by default and were not part of the "ALL" ciphersuite
3008 alias because they were not yet official; they could be
3009 explicitly requested by specifying the "AESdraft" ciphersuite
3010 group alias. In the final release of OpenSSL 0.9.7, the group
3011 alias is called "AES" and is part of "ALL".)
3012 [Ben Laurie, Steve Henson, Bodo Moeller]
3014 *) New function OCSP_copy_nonce() to copy nonce value (if present) from
3015 request to response.
3018 *) Functions for OCSP responders. OCSP_request_onereq_count(),
3019 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
3020 extract information from a certificate request. OCSP_response_create()
3021 creates a response and optionally adds a basic response structure.
3022 OCSP_basic_add1_status() adds a complete single response to a basic
3023 response and returns the OCSP_SINGLERESP structure just added (to allow
3024 extensions to be included for example). OCSP_basic_add1_cert() adds a
3025 certificate to a basic response and OCSP_basic_sign() signs a basic
3026 response with various flags. New helper functions ASN1_TIME_check()
3027 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
3028 (converts ASN1_TIME to GeneralizedTime).
3031 *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
3032 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
3033 structure from a certificate. X509_pubkey_digest() digests the public_key
3034 contents: this is used in various key identifiers.
3037 *) Make sk_sort() tolerate a NULL argument.
3038 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
3040 *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
3041 passed by the function are trusted implicitly. If any of them signed the
3042 response then it is assumed to be valid and is not verified.
3045 *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
3046 to data. This was previously part of the PKCS7 ASN1 code. This
3047 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
3048 [Steve Henson, reported by Kenneth R. Robinette
3049 <support@securenetterm.com>]
3051 *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
3052 routines: without these tracing memory leaks is very painful.
3053 Fix leaks in PKCS12 and PKCS7 routines.
3056 *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
3057 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
3058 effectively meant GeneralizedTime would never be used. Now it
3059 is initialised to -1 but X509_time_adj() now has to check the value
3060 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
3061 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
3062 [Steve Henson, reported by Kenneth R. Robinette
3063 <support@securenetterm.com>]
3065 *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
3066 result in a zero length in the ASN1_INTEGER structure which was
3067 not consistent with the structure when d2i_ASN1_INTEGER() was used
3068 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
3069 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
3070 where it did not print out a minus for negative ASN1_INTEGER.
3073 *) Add summary printout to ocsp utility. The various functions which
3074 convert status values to strings have been renamed to:
3075 OCSP_response_status_str(), OCSP_cert_status_str() and
3076 OCSP_crl_reason_str() and are no longer static. New options
3077 to verify nonce values and to disable verification. OCSP response
3078 printout format cleaned up.
3081 *) Add additional OCSP certificate checks. These are those specified
3082 in RFC2560. This consists of two separate checks: the CA of the
3083 certificate being checked must either be the OCSP signer certificate
3084 or the issuer of the OCSP signer certificate. In the latter case the
3085 OCSP signer certificate must contain the OCSP signing extended key
3086 usage. This check is performed by attempting to match the OCSP
3087 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
3088 in the OCSP_CERTID structures of the response.
3091 *) Initial OCSP certificate verification added to OCSP_basic_verify()
3092 and related routines. This uses the standard OpenSSL certificate
3093 verify routines to perform initial checks (just CA validity) and
3094 to obtain the certificate chain. Then additional checks will be
3095 performed on the chain. Currently the root CA is checked to see
3096 if it is explicitly trusted for OCSP signing. This is used to set
3097 a root CA as a global signing root: that is any certificate that
3098 chains to that CA is an acceptable OCSP signing certificate.
3101 *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
3102 extensions from a separate configuration file.
3103 As when reading extensions from the main configuration file,
3104 the '-extensions ...' option may be used for specifying the
3106 [Massimiliano Pala <madwolf@comune.modena.it>]
3108 *) New OCSP utility. Allows OCSP requests to be generated or
3109 read. The request can be sent to a responder and the output
3110 parsed, outputed or printed in text form. Not complete yet:
3111 still needs to check the OCSP response validity.
3114 *) New subcommands for 'openssl ca':
3115 'openssl ca -status <serial>' prints the status of the cert with
3116 the given serial number (according to the index file).
3117 'openssl ca -updatedb' updates the expiry status of certificates
3119 [Massimiliano Pala <madwolf@comune.modena.it>]
3121 *) New '-newreq-nodes' command option to CA.pl. This is like
3122 '-newreq', but calls 'openssl req' with the '-nodes' option
3123 so that the resulting key is not encrypted.
3124 [Damien Miller <djm@mindrot.org>]
3126 *) New configuration for the GNU Hurd.
3127 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
3129 *) Initial code to implement OCSP basic response verify. This
3130 is currently incomplete. Currently just finds the signer's
3131 certificate and verifies the signature on the response.
3134 *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
3135 value of OPENSSLDIR. This is available via the new '-d' option
3136 to 'openssl version', and is also included in 'openssl version -a'.
3139 *) Allowing defining memory allocation callbacks that will be given
3140 file name and line number information in additional arguments
3141 (a const char* and an int). The basic functionality remains, as
3142 well as the original possibility to just replace malloc(),
3143 realloc() and free() by functions that do not know about these
3144 additional arguments. To register and find out the current
3145 settings for extended allocation functions, the following
3146 functions are provided:
3148 CRYPTO_set_mem_ex_functions
3149 CRYPTO_set_locked_mem_ex_functions
3150 CRYPTO_get_mem_ex_functions
3151 CRYPTO_get_locked_mem_ex_functions
3153 These work the same way as CRYPTO_set_mem_functions and friends.
3154 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
3155 extended allocation function is enabled.
3156 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
3157 a conventional allocation function is enabled.
3158 [Richard Levitte, Bodo Moeller]
3160 *) Finish off removing the remaining LHASH function pointer casts.
3161 There should no longer be any prototype-casting required when using
3162 the LHASH abstraction, and any casts that remain are "bugs". See
3163 the callback types and macros at the head of lhash.h for details
3164 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
3167 *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
3168 If /dev/[u]random devices are not available or do not return enough
3169 entropy, EGD style sockets (served by EGD or PRNGD) will automatically
3171 The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
3172 /etc/entropy will be queried once each in this sequence, quering stops
3173 when enough entropy was collected without querying more sockets.
3176 *) Change the Unix RAND_poll() variant to be able to poll several
3177 random devices, as specified by DEVRANDOM, until a sufficient amount
3178 of data has been collected. We spend at most 10 ms on each file
3179 (select timeout) and read in non-blocking mode. DEVRANDOM now
3180 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
3181 (previously it was just the string "/dev/urandom"), so on typical
3182 platforms the 10 ms delay will never occur.
3183 Also separate out the Unix variant to its own file, rand_unix.c.
3184 For VMS, there's a currently-empty rand_vms.c.
3187 *) Move OCSP client related routines to ocsp_cl.c. These
3188 provide utility functions which an application needing
3189 to issue a request to an OCSP responder and analyse the
3190 response will typically need: as opposed to those which an
3191 OCSP responder itself would need which will be added later.
3193 OCSP_request_sign() signs an OCSP request with an API similar
3194 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
3195 response. OCSP_response_get1_basic() extracts basic response
3196 from response. OCSP_resp_find_status(): finds and extracts status
3197 information from an OCSP_CERTID structure (which will be created
3198 when the request structure is built). These are built from lower
3199 level functions which work on OCSP_SINGLERESP structures but
3200 wont normally be used unless the application wishes to examine
3201 extensions in the OCSP response for example.
3203 Replace nonce routines with a pair of functions.
3204 OCSP_request_add1_nonce() adds a nonce value and optionally
3205 generates a random value. OCSP_check_nonce() checks the
3206 validity of the nonce in an OCSP response.
3209 *) Change function OCSP_request_add() to OCSP_request_add0_id().
3210 This doesn't copy the supplied OCSP_CERTID and avoids the
3211 need to free up the newly created id. Change return type
3212 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
3213 This can then be used to add extensions to the request.
3214 Deleted OCSP_request_new(), since most of its functionality
3215 is now in OCSP_REQUEST_new() (and the case insensitive name
3216 clash) apart from the ability to set the request name which
3217 will be added elsewhere.
3220 *) Update OCSP API. Remove obsolete extensions argument from
3221 various functions. Extensions are now handled using the new
3222 OCSP extension code. New simple OCSP HTTP function which
3223 can be used to send requests and parse the response.
3226 *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
3227 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
3228 uses the special reorder version of SET OF to sort the attributes
3229 and reorder them to match the encoded order. This resolves a long
3230 standing problem: a verify on a PKCS7 structure just after signing
3231 it used to fail because the attribute order did not match the
3232 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
3233 it uses the received order. This is necessary to tolerate some broken
3234 software that does not order SET OF. This is handled by encoding
3235 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
3236 to produce the required SET OF.
3239 *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
3240 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
3241 files to get correct declarations of the ASN.1 item variables.
3244 *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
3245 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
3246 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
3247 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
3248 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
3249 ASN1_ITEM and no wrapper functions.
3252 *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
3253 replace the old function pointer based I/O routines. Change most of
3254 the *_d2i_bio() and *_d2i_fp() functions to use these.
3257 *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
3258 lines, recognice more "algorithms" that can be deselected, and make
3259 it complain about algorithm deselection that isn't recognised.
3262 *) New ASN1 functions to handle dup, sign, verify, digest, pack and
3263 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
3264 to use new functions. Add NO_ASN1_OLD which can be set to remove
3265 some old style ASN1 functions: this can be used to determine if old
3266 code will still work when these eventually go away.
3269 *) New extension functions for OCSP structures, these follow the
3270 same conventions as certificates and CRLs.
3273 *) New function X509V3_add1_i2d(). This automatically encodes and
3274 adds an extension. Its behaviour can be customised with various
3275 flags to append, replace or delete. Various wrappers added for
3276 certifcates and CRLs.
3279 *) Fix to avoid calling the underlying ASN1 print routine when
3280 an extension cannot be parsed. Correct a typo in the
3281 OCSP_SERVICELOC extension. Tidy up print OCSP format.
3284 *) Make mkdef.pl parse some of the ASN1 macros and add apropriate
3285 entries for variables.
3288 *) Add functionality to apps/openssl.c for detecting locking
3289 problems: As the program is single-threaded, all we have
3290 to do is register a locking callback using an array for
3291 storing which locks are currently held by the program.
3294 *) Use a lock around the call to CRYPTO_get_ex_new_index() in
3295 SSL_get_ex_data_X509_STORE_idx(), which is used in
3296 ssl_verify_cert_chain() and thus can be called at any time
3297 during TLS/SSL handshakes so that thread-safety is essential.
3298 Unfortunately, the ex_data design is not at all suited
3299 for multi-threaded use, so it probably should be abolished.
3302 *) Added Broadcom "ubsec" ENGINE to OpenSSL.
3303 [Broadcom, tweaked and integrated by Geoff Thorpe]
3305 *) Move common extension printing code to new function
3306 X509V3_print_extensions(). Reorganise OCSP print routines and
3307 implement some needed OCSP ASN1 functions. Add OCSP extensions.
3310 *) New function X509_signature_print() to remove duplication in some
3314 *) Add a special meaning when SET OF and SEQUENCE OF flags are both
3315 set (this was treated exactly the same as SET OF previously). This
3316 is used to reorder the STACK representing the structure to match the
3317 encoding. This will be used to get round a problem where a PKCS7
3318 structure which was signed could not be verified because the STACK
3319 order did not reflect the encoded order.
3322 *) Reimplement the OCSP ASN1 module using the new code.
3325 *) Update the X509V3 code to permit the use of an ASN1_ITEM structure
3326 for its ASN1 operations. The old style function pointers still exist
3327 for now but they will eventually go away.
3330 *) Merge in replacement ASN1 code from the ASN1 branch. This almost
3331 completely replaces the old ASN1 functionality with a table driven
3332 encoder and decoder which interprets an ASN1_ITEM structure describing
3333 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
3334 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
3335 has also been converted to the new form.
3338 *) Change BN_mod_exp_recp so that negative moduli are tolerated
3339 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
3340 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
3341 for negative moduli.
3344 *) Fix BN_uadd and BN_usub: Always return non-negative results instead
3345 of not touching the result's sign bit.
3348 *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
3352 *) Changed the LHASH code to use prototypes for callbacks, and created
3353 macros to declare and implement thin (optionally static) functions
3354 that provide type-safety and avoid function pointer casting for the
3355 type-specific callbacks.
3358 *) Added Kerberos Cipher Suites to be used with TLS, as written in
3360 [Veers Staats <staatsvr@asc.hpc.mil>,
3361 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
3363 *) Reformat the FAQ so the different questions and answers can be divided
3364 in sections depending on the subject.
3367 *) Have the zlib compression code load ZLIB.DLL dynamically under
3371 *) New function BN_mod_sqrt for computing square roots modulo a prime
3372 (using the probabilistic Tonelli-Shanks algorithm unless
3373 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
3374 be handled deterministically).
3375 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
3377 *) Make BN_mod_inverse faster by explicitly handling small quotients
3378 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
3379 512 bits], about 30% for larger ones [1024 or 2048 bits].)
3382 *) New function BN_kronecker.
3385 *) Fix BN_gcd so that it works on negative inputs; the result is
3386 positive unless both parameters are zero.
3387 Previously something reasonably close to an infinite loop was
3388 possible because numbers could be growing instead of shrinking
3389 in the implementation of Euclid's algorithm.
3392 *) Fix BN_is_word() and BN_is_one() macros to take into account the
3393 sign of the number in question.
3395 Fix BN_is_word(a,w) to work correctly for w == 0.
3397 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
3398 because its test if the absolute value of 'a' equals 'w'.
3399 Note that BN_abs_is_word does *not* handle w == 0 reliably;
3400 it exists mostly for use in the implementations of BN_is_zero(),
3401 BN_is_one(), and BN_is_word().
3404 *) New function BN_swap.
3407 *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
3408 the exponentiation functions are more likely to produce reasonable
3409 results on negative inputs.
3412 *) Change BN_mod_mul so that the result is always non-negative.
3413 Previously, it could be negative if one of the factors was negative;
3414 I don't think anyone really wanted that behaviour.
3417 *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
3418 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
3419 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
3420 and add new functions:
3429 BN_mod_lshift1_quick
3433 These functions always generate non-negative results.
3435 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
3436 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
3438 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
3439 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
3440 be reduced modulo m.
3441 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
3444 The following entry accidentily appeared in the CHANGES file
3445 distributed with OpenSSL 0.9.7. The modifications described in
3446 it do *not* apply to OpenSSL 0.9.7.
3448 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
3449 was actually never needed) and in BN_mul(). The removal in BN_mul()
3450 required a small change in bn_mul_part_recursive() and the addition
3451 of the functions bn_cmp_part_words(), bn_sub_part_words() and
3452 bn_add_part_words(), which do the same thing as bn_cmp_words(),
3453 bn_sub_words() and bn_add_words() except they take arrays with
3458 *) In 'openssl passwd', verify passwords read from the terminal
3459 unless the '-salt' option is used (which usually means that
3460 verification would just waste user's time since the resulting
3461 hash is going to be compared with some given password hash)
3462 or the new '-noverify' option is used.
3464 This is an incompatible change, but it does not affect
3465 non-interactive use of 'openssl passwd' (passwords on the command
3466 line, '-stdin' option, '-in ...' option) and thus should not
3470 *) Remove all references to RSAref, since there's no more need for it.
3473 *) Make DSO load along a path given through an environment variable
3474 (SHLIB_PATH) with shl_load().
3477 *) Constify the ENGINE code as a result of BIGNUM constification.
3478 Also constify the RSA code and most things related to it. In a
3479 few places, most notable in the depth of the ASN.1 code, ugly
3480 casts back to non-const were required (to be solved at a later
3484 *) Make it so the openssl application has all engines loaded by default.
3487 *) Constify the BIGNUM routines a little more.
3490 *) Add the following functions:
3492 ENGINE_load_cswift()
3494 ENGINE_load_atalla()
3496 ENGINE_load_builtin_engines()
3498 That way, an application can itself choose if external engines that
3499 are built-in in OpenSSL shall ever be used or not. The benefit is
3500 that applications won't have to be linked with libdl or other dso
3501 libraries unless it's really needed.
3503 Changed 'openssl engine' to load all engines on demand.
3504 Changed the engine header files to avoid the duplication of some
3505 declarations (they differed!).
3508 *) 'openssl engine' can now list capabilities.
3511 *) Better error reporting in 'openssl engine'.
3514 *) Never call load_dh_param(NULL) in s_server.
3517 *) Add engine application. It can currently list engines by name and
3518 identity, and test if they are actually available.
3521 *) Improve RPM specification file by forcing symbolic linking and making
3522 sure the installed documentation is also owned by root.root.
3523 [Damien Miller <djm@mindrot.org>]
3525 *) Give the OpenSSL applications more possibilities to make use of
3526 keys (public as well as private) handled by engines.
3529 *) Add OCSP code that comes from CertCo.
3532 *) Add VMS support for the Rijndael code.
3535 *) Added untested support for Nuron crypto accelerator.
3538 *) Add support for external cryptographic devices. This code was
3539 previously distributed separately as the "engine" branch.
3540 [Geoff Thorpe, Richard Levitte]
3542 *) Rework the filename-translation in the DSO code. It is now possible to
3543 have far greater control over how a "name" is turned into a filename
3544 depending on the operating environment and any oddities about the
3545 different shared library filenames on each system.
3548 *) Support threads on FreeBSD-elf in Configure.
3551 *) Fix for SHA1 assembly problem with MASM: it produces
3552 warnings about corrupt line number information when assembling
3553 with debugging information. This is caused by the overlapping
3555 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
3558 NCONF_get_number() has no error checking at all. As a replacement,
3559 NCONF_get_number_e() is defined (_e for "error checking") and is
3560 promoted strongly. The old NCONF_get_number is kept around for
3561 binary backward compatibility.
3562 Make it possible for methods to load from something other than a BIO,
3563 by providing a function pointer that is given a name instead of a BIO.
3564 For example, this could be used to load configuration data from an
3568 *) Fix for non blocking accept BIOs. Added new I/O special reason
3569 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
3570 with non blocking I/O was not possible because no retry code was
3571 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
3575 *) Added the beginnings of Rijndael support.
3578 *) Fix for bug in DirectoryString mask setting. Add support for
3579 X509_NAME_print_ex() in 'req' and X509_print_ex() function
3580 to allow certificate printing to more controllable, additional
3581 'certopt' option to 'x509' to allow new printing options to be
3585 *) Clean old EAY MD5 hack from e_os.h.
3588 Changes between 0.9.6l and 0.9.6m [17 Mar 2004]
3590 *) Fix null-pointer assignment in do_change_cipher_spec() revealed
3591 by using the Codenomicon TLS Test Tool (CVE-2004-0079)
3592 [Joe Orton, Steve Henson]
3594 Changes between 0.9.6k and 0.9.6l [04 Nov 2003]
3596 *) Fix additional bug revealed by the NISCC test suite:
3598 Stop bug triggering large recursion when presented with
3599 certain ASN.1 tags (CVE-2003-0851)
3602 Changes between 0.9.6j and 0.9.6k [30 Sep 2003]
3604 *) Fix various bugs revealed by running the NISCC test suite:
3606 Stop out of bounds reads in the ASN1 code when presented with
3607 invalid tags (CVE-2003-0543 and CVE-2003-0544).
3609 If verify callback ignores invalid public key errors don't try to check
3610 certificate signature with the NULL public key.
3614 *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
3615 if the server requested one: as stated in TLS 1.0 and SSL 3.0
3619 *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
3620 extra data after the compression methods not only for TLS 1.0
3621 but also for SSL 3.0 (as required by the specification).
3622 [Bodo Moeller; problem pointed out by Matthias Loepfe]
3624 *) Change X509_certificate_type() to mark the key as exported/exportable
3625 when it's 512 *bits* long, not 512 bytes.
3628 Changes between 0.9.6i and 0.9.6j [10 Apr 2003]
3630 *) Countermeasure against the Klima-Pokorny-Rosa extension of
3631 Bleichbacher's attack on PKCS #1 v1.5 padding: treat
3632 a protocol version number mismatch like a decryption error
3633 in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
3636 *) Turn on RSA blinding by default in the default implementation
3637 to avoid a timing attack. Applications that don't want it can call
3638 RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
3639 They would be ill-advised to do so in most cases.
3640 [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
3642 *) Change RSA blinding code so that it works when the PRNG is not
3643 seeded (in this case, the secret RSA exponent is abused as
3644 an unpredictable seed -- if it is not unpredictable, there
3645 is no point in blinding anyway). Make RSA blinding thread-safe
3646 by remembering the creator's thread ID in rsa->blinding and
3647 having all other threads use local one-time blinding factors
3648 (this requires more computation than sharing rsa->blinding, but
3649 avoids excessive locking; and if an RSA object is not shared
3650 between threads, blinding will still be very fast).
3653 Changes between 0.9.6h and 0.9.6i [19 Feb 2003]
3655 *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
3656 via timing by performing a MAC computation even if incorrrect
3657 block cipher padding has been found. This is a countermeasure
3658 against active attacks where the attacker has to distinguish
3659 between bad padding and a MAC verification error. (CVE-2003-0078)
3661 [Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
3662 Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
3663 Martin Vuagnoux (EPFL, Ilion)]
3665 Changes between 0.9.6g and 0.9.6h [5 Dec 2002]
3667 *) New function OPENSSL_cleanse(), which is used to cleanse a section of
3668 memory from it's contents. This is done with a counter that will
3669 place alternating values in each byte. This can be used to solve
3670 two issues: 1) the removal of calls to memset() by highly optimizing
3671 compilers, and 2) cleansing with other values than 0, since those can
3672 be read through on certain media, for example a swap space on disk.
3675 *) Bugfix: client side session caching did not work with external caching,
3676 because the session->cipher setting was not restored when reloading
3677 from the external cache. This problem was masked, when
3678 SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set.
3679 (Found by Steve Haslam <steve@araqnid.ddts.net>.)
3682 *) Fix client_certificate (ssl/s2_clnt.c): The permissible total
3683 length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
3684 [Zeev Lieber <zeev-l@yahoo.com>]
3686 *) Undo an undocumented change introduced in 0.9.6e which caused
3687 repeated calls to OpenSSL_add_all_ciphers() and
3688 OpenSSL_add_all_digests() to be ignored, even after calling
3692 *) Change the default configuration reader to deal with last line not
3693 being properly terminated.
3696 *) Change X509_NAME_cmp() so it applies the special rules on handling
3697 DN values that are of type PrintableString, as well as RDNs of type
3698 emailAddress where the value has the type ia5String.
3699 [stefank@valicert.com via Richard Levitte]
3701 *) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half
3702 the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
3703 doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
3704 the bitwise-OR of the two for use by the majority of applications
3705 wanting this behaviour, and update the docs. The documented
3706 behaviour and actual behaviour were inconsistent and had been
3707 changing anyway, so this is more a bug-fix than a behavioural
3709 [Geoff Thorpe, diagnosed by Nadav Har'El]
3711 *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
3712 (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
3715 *) Fix initialization code race conditions in
3716 SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),
3717 SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(),
3718 SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(),
3719 TLSv1_method(), TLSv1_client_method(), TLSv1_server_method(),
3720 ssl2_get_cipher_by_char(),
3721 ssl3_get_cipher_by_char().
3722 [Patrick McCormick <patrick@tellme.com>, Bodo Moeller]
3724 *) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
3725 the cached sessions are flushed, as the remove_cb() might use ex_data
3726 contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com>
3727 (see [openssl.org #212]).
3728 [Geoff Thorpe, Lutz Jaenicke]
3730 *) Fix typo in OBJ_txt2obj which incorrectly passed the content
3731 length, instead of the encoding length to d2i_ASN1_OBJECT.
3734 Changes between 0.9.6f and 0.9.6g [9 Aug 2002]
3736 *) [In 0.9.6g-engine release:]
3737 Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall').
3738 [Lynn Gazis <lgazis@rainbow.com>]
3740 Changes between 0.9.6e and 0.9.6f [8 Aug 2002]
3742 *) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX
3743 and get fix the header length calculation.
3744 [Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>,
3745 Alon Kantor <alonk@checkpoint.com> (and others),
3748 *) Use proper error handling instead of 'assertions' in buffer
3749 overflow checks added in 0.9.6e. This prevents DoS (the
3750 assertions could call abort()).
3751 [Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]
3753 Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
3755 *) Add various sanity checks to asn1_get_length() to reject
3756 the ASN1 length bytes if they exceed sizeof(long), will appear
3757 negative or the content length exceeds the length of the
3759 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
3761 *) Fix cipher selection routines: ciphers without encryption had no flags
3762 for the cipher strength set and where therefore not handled correctly
3763 by the selection routines (PR #130).
3766 *) Fix EVP_dsa_sha macro.
3770 SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
3771 for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
3772 that was added in OpenSSL 0.9.6d.
3774 As the countermeasure turned out to be incompatible with some
3775 broken SSL implementations, the new option is part of SSL_OP_ALL.
3776 SSL_OP_ALL is usually employed when compatibility with weird SSL
3777 implementations is desired (e.g. '-bugs' option to 's_client' and
3778 's_server'), so the new option is automatically set in many
3782 *) Changes in security patch:
3784 Changes marked "(CHATS)" were sponsored by the Defense Advanced
3785 Research Projects Agency (DARPA) and Air Force Research Laboratory,
3786 Air Force Materiel Command, USAF, under agreement number
3789 *) Add various sanity checks to asn1_get_length() to reject
3790 the ASN1 length bytes if they exceed sizeof(long), will appear
3791 negative or the content length exceeds the length of the
3792 supplied buffer. (CVE-2002-0659)
3793 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
3795 *) Assertions for various potential buffer overflows, not known to
3797 [Ben Laurie (CHATS)]
3799 *) Various temporary buffers to hold ASCII versions of integers were
3800 too small for 64 bit platforms. (CVE-2002-0655)
3801 [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
3803 *) Remote buffer overflow in SSL3 protocol - an attacker could
3804 supply an oversized session ID to a client. (CVE-2002-0656)
3805 [Ben Laurie (CHATS)]
3807 *) Remote buffer overflow in SSL2 protocol - an attacker could
3808 supply an oversized client master key. (CVE-2002-0656)
3809 [Ben Laurie (CHATS)]
3811 Changes between 0.9.6c and 0.9.6d [9 May 2002]
3813 *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
3814 encoded as NULL) with id-dsa-with-sha1.
3815 [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
3817 *) Check various X509_...() return values in apps/req.c.
3818 [Nils Larsch <nla@trustcenter.de>]
3820 *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
3821 an end-of-file condition would erronously be flagged, when the CRLF
3822 was just at the end of a processed block. The bug was discovered when
3823 processing data through a buffering memory BIO handing the data to a
3824 BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
3825 <ptsekov@syntrex.com> and Nedelcho Stanev.
3828 *) Implement a countermeasure against a vulnerability recently found
3829 in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
3830 before application data chunks to avoid the use of known IVs
3831 with data potentially chosen by the attacker.
3834 *) Fix length checks in ssl3_get_client_hello().
3837 *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
3838 to prevent ssl3_read_internal() from incorrectly assuming that
3839 ssl3_read_bytes() found application data while handshake
3840 processing was enabled when in fact s->s3->in_read_app_data was
3841 merely automatically cleared during the initial handshake.
3842 [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
3844 *) Fix object definitions for Private and Enterprise: they were not
3845 recognized in their shortname (=lowercase) representation. Extend
3846 obj_dat.pl to issue an error when using undefined keywords instead
3847 of silently ignoring the problem (Svenning Sorensen
3848 <sss@sss.dnsalias.net>).
3851 *) Fix DH_generate_parameters() so that it works for 'non-standard'
3852 generators, i.e. generators other than 2 and 5. (Previously, the
3853 code did not properly initialise the 'add' and 'rem' values to
3854 BN_generate_prime().)
3856 In the new general case, we do not insist that 'generator' is
3857 actually a primitive root: This requirement is rather pointless;
3858 a generator of the order-q subgroup is just as good, if not
3862 *) Map new X509 verification errors to alerts. Discovered and submitted by
3863 Tom Wu <tom@arcot.com>.
3866 *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
3867 returning non-zero before the data has been completely received
3868 when using non-blocking I/O.
3869 [Bodo Moeller; problem pointed out by John Hughes]
3871 *) Some of the ciphers missed the strength entry (SSL_LOW etc).
3872 [Ben Laurie, Lutz Jaenicke]
3874 *) Fix bug in SSL_clear(): bad sessions were not removed (found by
3875 Yoram Zahavi <YoramZ@gilian.com>).
3878 *) Add information about CygWin 1.3 and on, and preserve proper
3879 configuration for the versions before that.
3880 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
3882 *) Make removal from session cache (SSL_CTX_remove_session()) more robust:
3883 check whether we deal with a copy of a session and do not delete from
3884 the cache in this case. Problem reported by "Izhar Shoshani Levi"
3885 <izhar@checkpoint.com>.
3888 *) Do not store session data into the internal session cache, if it
3889 is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
3890 flag is set). Proposed by Aslam <aslam@funk.com>.
3893 *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
3897 *) [In 0.9.6d-engine release:]
3898 Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
3899 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
3901 *) Add the configuration target linux-s390x.
3902 [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
3904 *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
3905 ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
3906 variable as an indication that a ClientHello message has been
3907 received. As the flag value will be lost between multiple
3908 invocations of ssl3_accept when using non-blocking I/O, the
3909 function may not be aware that a handshake has actually taken
3910 place, thus preventing a new session from being added to the
3913 To avoid this problem, we now set s->new_session to 2 instead of
3914 using a local variable.
3915 [Lutz Jaenicke, Bodo Moeller]
3917 *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
3918 if the SSL_R_LENGTH_MISMATCH error is detected.
3919 [Geoff Thorpe, Bodo Moeller]
3921 *) New 'shared_ldflag' column in Configure platform table.
3924 *) Fix EVP_CIPHER_mode macro.
3925 ["Dan S. Camper" <dan@bti.net>]
3927 *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
3928 type, we must throw them away by setting rr->length to 0.
3929 [D P Chang <dpc@qualys.com>]
3931 Changes between 0.9.6b and 0.9.6c [21 dec 2001]
3933 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
3934 <Dominikus.Scherkl@biodata.com>. (The previous implementation
3935 worked incorrectly for those cases where range = 10..._2 and
3936 3*range is two bits longer than range.)
3939 *) Only add signing time to PKCS7 structures if it is not already
3943 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
3944 OBJ_ld_ce should be OBJ_id_ce.
3945 Also some ip-pda OIDs in crypto/objects/objects.txt were
3946 incorrect (cf. RFC 3039).
3947 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
3949 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
3950 returns early because it has nothing to do.
3951 [Andy Schneider <andy.schneider@bjss.co.uk>]
3953 *) [In 0.9.6c-engine release:]
3954 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
3955 [Andy Schneider <andy.schneider@bjss.co.uk>]
3957 *) [In 0.9.6c-engine release:]
3958 Add support for Cryptographic Appliance's keyserver technology.
3959 (Use engine 'keyclient')
3960 [Cryptographic Appliances and Geoff Thorpe]
3962 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
3963 is called via tools/c89.sh because arguments have to be
3964 rearranged (all '-L' options must appear before the first object
3966 [Richard Shapiro <rshapiro@abinitio.com>]
3968 *) [In 0.9.6c-engine release:]
3969 Add support for Broadcom crypto accelerator cards, backported
3971 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
3973 *) [In 0.9.6c-engine release:]
3974 Add support for SureWare crypto accelerator cards from
3975 Baltimore Technologies. (Use engine 'sureware')
3976 [Baltimore Technologies and Mark Cox]
3978 *) [In 0.9.6c-engine release:]
3979 Add support for crypto accelerator cards from Accelerated
3980 Encryption Processing, www.aep.ie. (Use engine 'aep')
3981 [AEP Inc. and Mark Cox]
3983 *) Add a configuration entry for gcc on UnixWare.
3984 [Gary Benson <gbenson@redhat.com>]
3986 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
3987 messages are stored in a single piece (fixed-length part and
3988 variable-length part combined) and fix various bugs found on the way.
3991 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
3992 instead. BIO_gethostbyname() does not know what timeouts are
3993 appropriate, so entries would stay in cache even when they have
3995 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
3997 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
3998 faced with a pathologically small ClientHello fragment that does
3999 not contain client_version: Instead of aborting with an error,
4000 simply choose the highest available protocol version (i.e.,
4001 TLS 1.0 unless it is disabled). In practice, ClientHello
4002 messages are never sent like this, but this change gives us
4003 strictly correct behaviour at least for TLS.
4006 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
4007 never resets s->method to s->ctx->method when called from within
4008 one of the SSL handshake functions.
4009 [Bodo Moeller; problem pointed out by Niko Baric]
4011 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
4012 (sent using the client's version number) if client_version is
4013 smaller than the protocol version in use. Also change
4014 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
4015 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
4016 the client will at least see that alert.
4019 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
4023 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
4024 client receives HelloRequest while in a handshake.
4025 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
4027 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
4028 should end in 'break', not 'goto end' which circuments various
4029 cleanups done in state SSL_ST_OK. But session related stuff
4030 must be disabled for SSL_ST_OK in the case that we just sent a
4033 Also avoid some overhead by not calling ssl_init_wbio_buffer()
4034 before just sending a HelloRequest.
4035 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
4037 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
4038 reveal whether illegal block cipher padding was found or a MAC
4039 verification error occured. (Neither SSLerr() codes nor alerts
4040 are directly visible to potential attackers, but the information
4041 may leak via logfiles.)
4043 Similar changes are not required for the SSL 2.0 implementation
4044 because the number of padding bytes is sent in clear for SSL 2.0,
4045 and the extra bytes are just ignored. However ssl/s2_pkt.c
4046 failed to verify that the purported number of padding bytes is in
4050 *) Add OpenUNIX-8 support including shared libraries
4051 (Boyd Lynn Gerber <gerberb@zenez.com>).
4054 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
4055 'wristwatch attack' using huge encoding parameters (cf.
4056 James H. Manger's CRYPTO 2001 paper). Note that the
4057 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
4058 encoding parameters and hence was not vulnerable.
4061 *) BN_sqr() bug fix.
4062 [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
4064 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
4065 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
4066 followed by modular reduction.
4067 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
4069 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
4070 equivalent based on BN_pseudo_rand() instead of BN_rand().
4073 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
4074 This function was broken, as the check for a new client hello message
4075 to handle SGC did not allow these large messages.
4076 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
4079 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
4082 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
4083 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
4086 *) Rework the configuration and shared library support for Tru64 Unix.
4087 The configuration part makes use of modern compiler features and
4088 still retains old compiler behavior for those that run older versions
4089 of the OS. The shared library support part includes a variant that
4090 uses the RPATH feature, and is available through the special
4091 configuration target "alpha-cc-rpath", which will never be selected
4093 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
4095 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
4096 with the same message size as in ssl3_get_certificate_request().
4097 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
4098 messages might inadvertently be reject as too long.
4099 [Petr Lampa <lampa@fee.vutbr.cz>]
4101 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
4104 *) Modified SSL library such that the verify_callback that has been set
4105 specificly for an SSL object with SSL_set_verify() is actually being
4106 used. Before the change, a verify_callback set with this function was
4107 ignored and the verify_callback() set in the SSL_CTX at the time of
4108 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
4109 to allow the necessary settings.
4112 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
4113 explicitly to NULL, as at least on Solaris 8 this seems not always to be
4114 done automatically (in contradiction to the requirements of the C
4115 standard). This made problems when used from OpenSSH.
4118 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
4119 dh->length and always used
4121 BN_rand_range(priv_key, dh->p).
4123 BN_rand_range() is not necessary for Diffie-Hellman, and this
4124 specific range makes Diffie-Hellman unnecessarily inefficient if
4125 dh->length (recommended exponent length) is much smaller than the
4126 length of dh->p. We could use BN_rand_range() if the order of
4127 the subgroup was stored in the DH structure, but we only have
4132 BN_rand(priv_key, l, ...)
4134 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
4140 RSA_eay_public_encrypt
4141 RSA_eay_private_decrypt
4142 RSA_eay_private_encrypt (signing)
4143 RSA_eay_public_decrypt (signature verification)
4145 (default implementations for RSA_public_encrypt,
4146 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
4147 always reject numbers >= n.
4150 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
4151 to synchronize access to 'locking_thread'. This is necessary on
4152 systems where access to 'locking_thread' (an 'unsigned long'
4153 variable) is not atomic.
4156 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
4157 *before* setting the 'crypto_lock_rand' flag. The previous code had
4158 a race condition if 0 is a valid thread ID.
4159 [Travis Vitek <vitek@roguewave.com>]
4161 *) Add support for shared libraries under Irix.
4162 [Albert Chin-A-Young <china@thewrittenword.com>]
4164 *) Add configuration option to build on Linux on both big-endian and
4166 [Ralf Baechle <ralf@uni-koblenz.de>]
4168 *) Add the possibility to create shared libraries on HP-UX.
4171 Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
4173 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
4174 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
4175 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
4176 PRNG state recovery was possible based on the output of
4177 one PRNG request appropriately sized to gain knowledge on
4178 'md' followed by enough consecutive 1-byte PRNG requests
4179 to traverse all of 'state'.
4181 1. When updating 'md_local' (the current thread's copy of 'md')
4182 during PRNG output generation, hash all of the previous
4183 'md_local' value, not just the half used for PRNG output.
4185 2. Make the number of bytes from 'state' included into the hash
4186 independent from the number of PRNG bytes requested.
4188 The first measure alone would be sufficient to avoid
4189 Markku-Juhani's attack. (Actually it had never occurred
4190 to me that the half of 'md_local' used for chaining was the
4191 half from which PRNG output bytes were taken -- I had always
4192 assumed that the secret half would be used.) The second
4193 measure makes sure that additional data from 'state' is never
4194 mixed into 'md_local' in small portions; this heuristically
4195 further strengthens the PRNG.
4198 *) Fix crypto/bn/asm/mips3.s.
4201 *) When only the key is given to "enc", the IV is undefined. Print out
4202 an error message in this case.
4205 *) Handle special case when X509_NAME is empty in X509 printing routines.
4208 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
4209 positive and less than q.
4212 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
4213 used: it isn't thread safe and the add_lock_callback should handle
4215 [Paul Rose <Paul.Rose@bridge.com>]
4217 *) Verify that incoming data obeys the block size in
4218 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
4222 [Ulf Möller, Bodo Möller]
4224 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
4225 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
4226 when fixing the server behaviour for backwards-compatible 'client
4227 hello' messages. (Note that the attack is impractical against
4228 SSL 3.0 and TLS 1.0 anyway because length and version checking
4229 means that the probability of guessing a valid ciphertext is
4230 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
4233 Before 0.9.5, the countermeasure (hide the error by generating a
4234 random 'decryption result') did not work properly because
4235 ERR_clear_error() was missing, meaning that SSL_get_error() would
4236 detect the supposedly ignored error.
4238 Both problems are now fixed.
4241 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
4242 (previously it was 1024).
4245 *) Fix for compatibility mode trust settings: ignore trust settings
4246 unless some valid trust or reject settings are present.
4249 *) Fix for blowfish EVP: its a variable length cipher.
4252 *) Fix various bugs related to DSA S/MIME verification. Handle missing
4253 parameters in DSA public key structures and return an error in the
4254 DSA routines if parameters are absent.
4257 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
4258 in the current directory if neither $RANDFILE nor $HOME was set.
4259 RAND_file_name() in 0.9.6a returned NULL in this case. This has
4260 caused some confusion to Windows users who haven't defined $HOME.
4261 Thus RAND_file_name() is changed again: e_os.h can define a
4262 DEFAULT_HOME, which will be used if $HOME is not set.
4263 For Windows, we use "C:"; on other platforms, we still require
4264 environment variables.
4266 *) Move 'if (!initialized) RAND_poll()' into regions protected by
4267 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
4268 having multiple threads call RAND_poll() concurrently.
4271 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
4272 combination of a flag and a thread ID variable.
4273 Otherwise while one thread is in ssleay_rand_bytes (which sets the
4274 flag), *other* threads can enter ssleay_add_bytes without obeying
4275 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
4276 that they do not hold after the first thread unsets add_do_not_lock).
4279 *) Change bctest again: '-x' expressions are not available in all
4283 Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
4285 *) Fix a couple of memory leaks in PKCS7_dataDecode()
4286 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
4288 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
4289 the default extension for executables, if any. Also, make the perl
4290 scripts that use symlink() to test if it really exists and use "cp"
4291 if it doesn't. All this made OpenSSL compilable and installable in
4295 *) Fix for asn1_GetSequence() for indefinite length constructed data.
4296 If SEQUENCE is length is indefinite just set c->slen to the total
4297 amount of data available.
4298 [Steve Henson, reported by shige@FreeBSD.org]
4299 [This change does not apply to 0.9.7.]
4301 *) Change bctest to avoid here-documents inside command substitution
4302 (workaround for FreeBSD /bin/sh bug).
4303 For compatibility with Ultrix, avoid shell functions (introduced
4304 in the bctest version that searches along $PATH).
4307 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
4308 with des_encrypt() defined on some operating systems, like Solaris
4312 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
4313 On the Importance of Eliminating Errors in Cryptographic
4314 Computations, J. Cryptology 14 (2001) 2, 101-119,
4315 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
4318 *) MIPS assembler BIGNUM division bug fix.
4321 *) Disabled incorrect Alpha assembler code.
4324 *) Fix PKCS#7 decode routines so they correctly update the length
4325 after reading an EOC for the EXPLICIT tag.
4327 [This change does not apply to 0.9.7.]
4329 *) Fix bug in PKCS#12 key generation routines. This was triggered
4330 if a 3DES key was generated with a 0 initial byte. Include
4331 PKCS12_BROKEN_KEYGEN compilation option to retain the old
4332 (but broken) behaviour.
4335 *) Enhance bctest to search for a working bc along $PATH and print
4337 [Tim Rice <tim@multitalents.net> via Richard Levitte]
4339 *) Fix memory leaks in err.c: free err_data string if necessary;
4340 don't write to the wrong index in ERR_set_error_data.
4343 *) Implement ssl23_peek (analogous to ssl23_read), which previously
4347 *) Replace rdtsc with _emit statements for VC++ version 5.
4348 [Jeremy Cooper <jeremy@baymoo.org>]
4350 *) Make it possible to reuse SSLv2 sessions.
4353 *) In copy_email() check for >= 0 as a return value for
4354 X509_NAME_get_index_by_NID() since 0 is a valid index.
4355 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
4357 *) Avoid coredump with unsupported or invalid public keys by checking if
4358 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
4359 PKCS7_verify() fails with non detached data.
4362 *) Don't use getenv in library functions when run as setuid/setgid.
4363 New function OPENSSL_issetugid().
4366 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
4367 due to incorrect handling of multi-threading:
4369 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
4371 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
4373 3. Count how many times MemCheck_off() has been called so that
4374 nested use can be treated correctly. This also avoids
4375 inband-signalling in the previous code (which relied on the
4376 assumption that thread ID 0 is impossible).
4379 *) Add "-rand" option also to s_client and s_server.
4382 *) Fix CPU detection on Irix 6.x.
4383 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
4384 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
4386 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
4389 [This change does not apply to 0.9.7.]
4391 *) Use the cached encoding of an X509_NAME structure rather than
4392 copying it. This is apparently the reason for the libsafe "errors"
4393 but the code is actually correct.
4396 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
4397 Bleichenbacher's DSA attack.
4398 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
4399 to be set and top=0 forces the highest bit to be set; top=-1 is new
4400 and leaves the highest bit random.
4401 [Ulf Moeller, Bodo Moeller]
4403 *) In the NCONF_...-based implementations for CONF_... queries
4404 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
4405 a temporary CONF structure with the data component set to NULL
4406 (which gives segmentation faults in lh_retrieve).
4407 Instead, use NULL for the CONF pointer in CONF_get_string and
4408 CONF_get_number (which may use environment variables) and directly
4409 return NULL from CONF_get_section.
4412 *) Fix potential buffer overrun for EBCDIC.
4415 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
4416 keyUsage if basicConstraints absent for a CA.
4419 *) Make SMIME_write_PKCS7() write mail header values with a format that
4420 is more generally accepted (no spaces before the semicolon), since
4421 some programs can't parse those values properly otherwise. Also make
4422 sure BIO's that break lines after each write do not create invalid
4426 *) Make the CRL encoding routines work with empty SEQUENCE OF. The
4427 macros previously used would not encode an empty SEQUENCE OF
4428 and break the signature.
4430 [This change does not apply to 0.9.7.]
4432 *) Zero the premaster secret after deriving the master secret in
4436 *) Add some EVP_add_digest_alias registrations (as found in
4437 OpenSSL_add_all_digests()) to SSL_library_init()
4438 aka OpenSSL_add_ssl_algorithms(). This provides improved
4439 compatibility with peers using X.509 certificates
4440 with unconventional AlgorithmIdentifier OIDs.
4443 *) Fix for Irix with NO_ASM.
4444 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
4446 *) ./config script fixes.
4447 [Ulf Moeller, Richard Levitte]
4449 *) Fix 'openssl passwd -1'.
4452 *) Change PKCS12_key_gen_asc() so it can cope with non null
4453 terminated strings whose length is passed in the passlen
4454 parameter, for example from PEM callbacks. This was done
4455 by adding an extra length parameter to asc2uni().
4456 [Steve Henson, reported by <oddissey@samsung.co.kr>]
4458 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
4459 call failed, free the DSA structure.
4462 *) Fix to uni2asc() to cope with zero length Unicode strings.
4463 These are present in some PKCS#12 files.
4466 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
4467 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
4468 when writing a 32767 byte record.
4469 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
4471 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
4472 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
4474 (RSA objects have a reference count access to which is protected
4475 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
4476 so they are meant to be shared between threads.)
4477 [Bodo Moeller, Geoff Thorpe; original patch submitted by
4478 "Reddie, Steven" <Steven.Reddie@ca.com>]
4480 *) Fix a deadlock in CRYPTO_mem_leaks().
4483 *) Use better test patterns in bntest.
4486 *) rand_win.c fix for Borland C.
4489 *) BN_rshift bugfix for n == 0.
4492 *) Add a 'bctest' script that checks for some known 'bc' bugs
4493 so that 'make test' does not abort just because 'bc' is broken.
4496 *) Store verify_result within SSL_SESSION also for client side to
4497 avoid potential security hole. (Re-used sessions on the client side
4498 always resulted in verify_result==X509_V_OK, not using the original
4499 result of the server certificate verification.)
4502 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
4503 SSL3_RT_APPLICATION_DATA, return 0.
4504 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
4508 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
4509 releases, have been re-implemented by renaming the previous
4510 implementations of ssl2_read and ssl3_read to ssl2_read_internal
4511 and ssl3_read_internal, respectively, and adding 'peek' parameters
4512 to them. The new ssl[23]_{read,peek} functions are calls to
4513 ssl[23]_read_internal with the 'peek' flag set appropriately.
4514 A 'peek' parameter has also been added to ssl3_read_bytes, which
4515 does the actual work for ssl3_read_internal.
4518 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
4519 the method-specific "init()" handler. Also clean up ex_data after
4520 calling the method-specific "finish()" handler. Previously, this was
4521 happening the other way round.
4524 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
4525 The previous value, 12, was not always sufficient for BN_mod_exp().
4528 *) Make sure that shared libraries get the internal name engine with
4529 the full version number and not just 0. This should mark the
4530 shared libraries as not backward compatible. Of course, this should
4531 be changed again when we can guarantee backward binary compatibility.
4534 *) Fix typo in get_cert_by_subject() in by_dir.c
4535 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
4537 *) Rework the system to generate shared libraries:
4539 - Make note of the expected extension for the shared libraries and
4540 if there is a need for symbolic links from for example libcrypto.so.0
4541 to libcrypto.so.0.9.7. There is extended info in Configure for
4544 - Make as few rebuilds of the shared libraries as possible.
4546 - Still avoid linking the OpenSSL programs with the shared libraries.
4548 - When installing, install the shared libraries separately from the
4552 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
4554 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
4555 and not in SSL_clear because the latter is also used by the
4556 accept/connect functions; previously, the settings made by
4557 SSL_set_read_ahead would be lost during the handshake.
4558 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
4560 *) Correct util/mkdef.pl to be selective about disabled algorithms.
4561 Previously, it would create entries for disableed algorithms no
4565 *) Added several new manual pages for SSL_* function.
4568 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
4570 *) In ssl23_get_client_hello, generate an error message when faced
4571 with an initial SSL 3.0/TLS record that is too small to contain the
4572 first two bytes of the ClientHello message, i.e. client_version.
4573 (Note that this is a pathologic case that probably has never happened
4574 in real life.) The previous approach was to use the version number
4575 from the record header as a substitute; but our protocol choice
4576 should not depend on that one because it is not authenticated
4577 by the Finished messages.
4580 *) More robust randomness gathering functions for Windows.
4581 [Jeffrey Altman <jaltman@columbia.edu>]
4583 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
4584 not set then we don't setup the error code for issuer check errors
4585 to avoid possibly overwriting other errors which the callback does
4586 handle. If an application does set the flag then we assume it knows
4587 what it is doing and can handle the new informational codes
4591 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
4592 a general "ANY" type, as such it should be able to decode anything
4593 including tagged types. However it didn't check the class so it would
4594 wrongly interpret tagged types in the same way as their universal
4595 counterpart and unknown types were just rejected. Changed so that the
4596 tagged and unknown types are handled in the same way as a SEQUENCE:
4597 that is the encoding is stored intact. There is also a new type
4598 "V_ASN1_OTHER" which is used when the class is not universal, in this
4599 case we have no idea what the actual type is so we just lump them all
4603 *) On VMS, stdout may very well lead to a file that is written to
4604 in a record-oriented fashion. That means that every write() will
4605 write a separate record, which will be read separately by the
4606 programs trying to read from it. This can be very confusing.
4608 The solution is to put a BIO filter in the way that will buffer
4609 text until a linefeed is reached, and then write everything a
4610 line at a time, so every record written will be an actual line,
4611 not chunks of lines and not (usually doesn't happen, but I've
4612 seen it once) several lines in one record. BIO_f_linebuffer() is
4615 Currently, it's a VMS-only method, because that's where it has
4616 been tested well enough.
4619 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
4620 it can return incorrect results.
4621 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
4622 but it was in 0.9.6-beta[12].)
4625 *) Disable the check for content being present when verifying detached
4626 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
4627 include zero length content when signing messages.
4630 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
4631 BIO_ctrl (for BIO pairs).
4634 *) Add DSO method for VMS.
4637 *) Bug fix: Montgomery multiplication could produce results with the
4641 *) Add RPM specification openssl.spec and modify it to build three
4642 packages. The default package contains applications, application
4643 documentation and run-time libraries. The devel package contains
4644 include files, static libraries and function documentation. The
4645 doc package contains the contents of the doc directory. The original
4646 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
4649 *) Add a large number of documentation files for many SSL routines.
4650 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
4652 *) Add a configuration entry for Sony News 4.
4653 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
4655 *) Don't set the two most significant bits to one when generating a
4656 random number < q in the DSA library.
4659 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
4660 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
4661 the underlying transport is blocking) if a handshake took place.
4662 (The default behaviour is needed by applications such as s_client
4663 and s_server that use select() to determine when to use SSL_read;
4664 but for applications that know in advance when to expect data, it
4665 just makes things more complicated.)
4668 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
4672 *) Add a few more EBCDIC conditionals that make `req' and `x509'
4673 work better on such systems.
4674 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4676 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
4677 Update PKCS12_parse() so it copies the friendlyName and the
4678 keyid to the certificates aux info.
4681 *) Fix bug in PKCS7_verify() which caused an infinite loop
4682 if there was more than one signature.
4683 [Sven Uszpelkat <su@celocom.de>]
4685 *) Major change in util/mkdef.pl to include extra information
4686 about each symbol, as well as presentig variables as well
4687 as functions. This change means that there's n more need
4688 to rebuild the .num files when some algorithms are excluded.
4691 *) Allow the verify time to be set by an application,
4692 rather than always using the current time.
4695 *) Phase 2 verify code reorganisation. The certificate
4696 verify code now looks up an issuer certificate by a
4697 number of criteria: subject name, authority key id
4698 and key usage. It also verifies self signed certificates
4699 by the same criteria. The main comparison function is
4700 X509_check_issued() which performs these checks.
4702 Lot of changes were necessary in order to support this
4703 without completely rewriting the lookup code.
4705 Authority and subject key identifier are now cached.
4707 The LHASH 'certs' is X509_STORE has now been replaced
4708 by a STACK_OF(X509_OBJECT). This is mainly because an
4709 LHASH can't store or retrieve multiple objects with
4710 the same hash value.
4712 As a result various functions (which were all internal
4713 use only) have changed to handle the new X509_STORE
4714 structure. This will break anything that messed round
4715 with X509_STORE internally.
4717 The functions X509_STORE_add_cert() now checks for an
4718 exact match, rather than just subject name.
4720 The X509_STORE API doesn't directly support the retrieval
4721 of multiple certificates matching a given criteria, however
4722 this can be worked round by performing a lookup first
4723 (which will fill the cache with candidate certificates)
4724 and then examining the cache for matches. This is probably
4725 the best we can do without throwing out X509_LOOKUP
4726 entirely (maybe later...).
4728 The X509_VERIFY_CTX structure has been enhanced considerably.
4730 All certificate lookup operations now go via a get_issuer()
4731 callback. Although this currently uses an X509_STORE it
4732 can be replaced by custom lookups. This is a simple way
4733 to bypass the X509_STORE hackery necessary to make this
4734 work and makes it possible to use more efficient techniques
4735 in future. A very simple version which uses a simple
4736 STACK for its trusted certificate store is also provided
4737 using X509_STORE_CTX_trusted_stack().
4739 The verify_cb() and verify() callbacks now have equivalents
4740 in the X509_STORE_CTX structure.
4742 X509_STORE_CTX also has a 'flags' field which can be used
4743 to customise the verify behaviour.
4746 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
4747 excludes S/MIME capabilities.
4750 *) When a certificate request is read in keep a copy of the
4751 original encoding of the signed data and use it when outputing
4752 again. Signatures then use the original encoding rather than
4753 a decoded, encoded version which may cause problems if the
4754 request is improperly encoded.
4757 *) For consistency with other BIO_puts implementations, call
4758 buffer_write(b, ...) directly in buffer_puts instead of calling
4761 In BIO_puts, increment b->num_write as in BIO_write.
4762 [Peter.Sylvester@EdelWeb.fr]
4764 *) Fix BN_mul_word for the case where the word is 0. (We have to use
4765 BN_zero, we may not return a BIGNUM with an array consisting of
4769 *) Avoid calling abort() from within the library when problems are
4770 detected, except if preprocessor symbols have been defined
4771 (such as REF_CHECK, BN_DEBUG etc.).
4774 *) New openssl application 'rsautl'. This utility can be
4775 used for low level RSA operations. DER public key
4776 BIO/fp routines also added.
4779 *) New Configure entry and patches for compiling on QNX 4.
4780 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
4782 *) A demo state-machine implementation was sponsored by
4783 Nuron (http://www.nuron.com/) and is now available in
4784 demos/state_machine.
4787 *) New options added to the 'dgst' utility for signature
4788 generation and verification.
4791 *) Unrecognized PKCS#7 content types are now handled via a
4792 catch all ASN1_TYPE structure. This allows unsupported
4793 types to be stored as a "blob" and an application can
4794 encode and decode it manually.
4797 *) Fix various signed/unsigned issues to make a_strex.c
4799 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
4801 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
4802 length if passed a buffer. ASN1_INTEGER_to_BN failed
4803 if passed a NULL BN and its argument was negative.
4804 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
4806 *) Modification to PKCS#7 encoding routines to output definite
4807 length encoding. Since currently the whole structures are in
4808 memory there's not real point in using indefinite length
4809 constructed encoding. However if OpenSSL is compiled with
4810 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
4813 *) Added BIO_vprintf() and BIO_vsnprintf().
4816 *) Added more prefixes to parse for in the the strings written
4817 through a logging bio, to cover all the levels that are available
4818 through syslog. The prefixes are now:
4820 PANIC, EMERG, EMR => LOG_EMERG
4821 ALERT, ALR => LOG_ALERT
4822 CRIT, CRI => LOG_CRIT
4823 ERROR, ERR => LOG_ERR
4824 WARNING, WARN, WAR => LOG_WARNING
4825 NOTICE, NOTE, NOT => LOG_NOTICE
4826 INFO, INF => LOG_INFO
4827 DEBUG, DBG => LOG_DEBUG
4829 and as before, if none of those prefixes are present at the
4830 beginning of the string, LOG_ERR is chosen.
4832 On Win32, the LOG_* levels are mapped according to this:
4834 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
4835 LOG_WARNING => EVENTLOG_WARNING_TYPE
4836 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
4840 *) Made it possible to reconfigure with just the configuration
4841 argument "reconf" or "reconfigure". The command line arguments
4842 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
4843 and are retrieved from there when reconfiguring.
4847 [Assar Westerlund <assar@sics.se>, Richard Levitte]
4849 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
4852 *) The obj_dat.pl script was messing up the sorting of object
4853 names. The reason was that it compared the quoted version
4854 of strings as a result "OCSP" > "OCSP Signing" because
4855 " > SPACE. Changed script to store unquoted versions of
4856 names and add quotes on output. It was also omitting some
4857 names from the lookup table if they were given a default
4858 value (that is if SN is missing it is given the same
4859 value as LN and vice versa), these are now added on the
4860 grounds that if an object has a name we should be able to
4861 look it up. Finally added warning output when duplicate
4862 short or long names are found.
4865 *) Changes needed for Tandem NSK.
4866 [Scott Uroff <scott@xypro.com>]
4868 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
4869 RSA_padding_check_SSLv23(), special padding was never detected
4870 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
4871 version rollback attacks was not effective.
4873 In s23_clnt.c, don't use special rollback-attack detection padding
4874 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
4875 client; similarly, in s23_srvr.c, don't do the rollback check if
4876 SSL 2.0 is the only protocol enabled in the server.
4879 *) Make it possible to get hexdumps of unprintable data with 'openssl
4880 asn1parse'. By implication, the functions ASN1_parse_dump() and
4881 BIO_dump_indent() are added.
4884 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
4885 these print out strings and name structures based on various
4886 flags including RFC2253 support and proper handling of
4887 multibyte characters. Added options to the 'x509' utility
4888 to allow the various flags to be set.
4891 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
4892 Also change the functions X509_cmp_current_time() and
4893 X509_gmtime_adj() work with an ASN1_TIME structure,
4894 this will enable certificates using GeneralizedTime in validity
4895 dates to be checked.
4898 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
4899 negative public key encodings) on by default,
4900 NO_NEG_PUBKEY_BUG can be set to disable it.
4903 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
4904 content octets. An i2c_ASN1_OBJECT is unnecessary because
4905 the encoding can be trivially obtained from the structure.
4908 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
4909 not read locks (CRYPTO_r_[un]lock).
4912 *) A first attempt at creating official support for shared
4913 libraries through configuration. I've kept it so the
4914 default is static libraries only, and the OpenSSL programs
4915 are always statically linked for now, but there are
4916 preparations for dynamic linking in place.
4917 This has been tested on Linux and Tru64.
4920 *) Randomness polling function for Win9x, as described in:
4921 Peter Gutmann, Software Generation of Practically Strong
4925 *) Fix so PRNG is seeded in req if using an already existing
4929 *) New options to smime application. -inform and -outform
4930 allow alternative formats for the S/MIME message including
4931 PEM and DER. The -content option allows the content to be
4932 specified separately. This should allow things like Netscape
4933 form signing output easier to verify.
4936 *) Fix the ASN1 encoding of tags using the 'long form'.
4939 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
4940 STRING types. These convert content octets to and from the
4941 underlying type. The actual tag and length octets are
4942 already assumed to have been read in and checked. These
4943 are needed because all other string types have virtually
4944 identical handling apart from the tag. By having versions
4945 of the ASN1 functions that just operate on content octets
4946 IMPLICIT tagging can be handled properly. It also allows
4947 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
4948 and ASN1_INTEGER are identical apart from the tag.
4951 *) Change the handling of OID objects as follows:
4953 - New object identifiers are inserted in objects.txt, following
4954 the syntax given in objects.README.
4955 - objects.pl is used to process obj_mac.num and create a new
4957 - obj_dat.pl is used to create a new obj_dat.h, using the data in
4960 This is currently kind of a hack, and the perl code in objects.pl
4961 isn't very elegant, but it works as I intended. The simplest way
4962 to check that it worked correctly is to look in obj_dat.h and
4963 check the array nid_objs and make sure the objects haven't moved
4964 around (this is important!). Additions are OK, as well as
4965 consistent name changes.
4968 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
4971 *) Addition of the command line parameter '-rand file' to 'openssl req'.
4972 The given file adds to whatever has already been seeded into the
4973 random pool through the RANDFILE configuration file option or
4974 environment variable, or the default random state file.
4977 *) mkstack.pl now sorts each macro group into lexical order.
4978 Previously the output order depended on the order the files
4979 appeared in the directory, resulting in needless rewriting
4983 *) Patches to make OpenSSL compile under Win32 again. Mostly
4984 work arounds for the VC++ problem that it treats func() as
4985 func(void). Also stripped out the parts of mkdef.pl that
4986 added extra typesafe functions: these no longer exist.
4989 *) Reorganisation of the stack code. The macros are now all
4990 collected in safestack.h . Each macro is defined in terms of
4991 a "stack macro" of the form SKM_<name>(type, a, b). The
4992 DEBUG_SAFESTACK is now handled in terms of function casts,
4993 this has the advantage of retaining type safety without the
4994 use of additional functions. If DEBUG_SAFESTACK is not defined
4995 then the non typesafe macros are used instead. Also modified the
4996 mkstack.pl script to handle the new form. Needs testing to see
4997 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
4998 the default if no major problems. Similar behaviour for ASN1_SET_OF
4999 and PKCS12_STACK_OF.
5002 *) When some versions of IIS use the 'NET' form of private key the
5003 key derivation algorithm is different. Normally MD5(password) is
5004 used as a 128 bit RC4 key. In the modified case
5005 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
5006 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
5007 as the old Netscape_RSA functions except they have an additional
5008 'sgckey' parameter which uses the modified algorithm. Also added
5009 an -sgckey command line option to the rsa utility. Thanks to
5010 Adrian Peck <bertie@ncipher.com> for posting details of the modified
5011 algorithm to openssl-dev.
5014 *) The evp_local.h macros were using 'c.##kname' which resulted in
5015 invalid expansion on some systems (SCO 5.0.5 for example).
5016 Corrected to 'c.kname'.
5017 [Phillip Porch <root@theporch.com>]
5019 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
5020 a STACK of email addresses from a certificate or request, these look
5021 in the subject name and the subject alternative name extensions and
5022 omit any duplicate addresses.
5025 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
5026 This makes DSA verification about 2 % faster.
5029 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
5030 (meaning that now 2^5 values will be precomputed, which is only 4 KB
5031 plus overhead for 1024 bit moduli).
5032 This makes exponentiations about 0.5 % faster for 1024 bit
5033 exponents (as measured by "openssl speed rsa2048").
5036 *) Rename memory handling macros to avoid conflicts with other
5038 Malloc => OPENSSL_malloc
5039 Malloc_locked => OPENSSL_malloc_locked
5040 Realloc => OPENSSL_realloc
5041 Free => OPENSSL_free
5044 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
5045 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
5048 *) CygWin32 support.
5049 [John Jarvie <jjarvie@newsguy.com>]
5051 *) The type-safe stack code has been rejigged. It is now only compiled
5052 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
5053 by default all type-specific stack functions are "#define"d back to
5054 standard stack functions. This results in more streamlined output
5055 but retains the type-safety checking possibilities of the original
5059 *) The STACK code has been cleaned up, and certain type declarations
5060 that didn't make a lot of sense have been brought in line. This has
5061 also involved a cleanup of sorts in safestack.h to more correctly
5062 map type-safe stack functions onto their plain stack counterparts.
5063 This work has also resulted in a variety of "const"ifications of
5064 lots of the code, especially "_cmp" operations which should normally
5065 be prototyped with "const" parameters anyway.
5068 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
5069 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
5070 (The PRNG state consists of two parts, the large pool 'state' and 'md',
5071 where all of 'md' is used each time the PRNG is used, but 'state'
5072 is used only indexed by a cyclic counter. As entropy may not be
5073 well distributed from the beginning, 'md' is important as a
5074 chaining variable. However, the output function chains only half
5075 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
5076 all of 'md', and seeding with STATE_SIZE dummy bytes will result
5077 in all of 'state' being rewritten, with the new values depending
5078 on virtually all of 'md'. This overcomes the 80 bit limitation.)
5081 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
5082 the handshake is continued after ssl_verify_cert_chain();
5083 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
5084 can lead to 'unexplainable' connection aborts later.
5085 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
5087 *) Major EVP API cipher revision.
5088 Add hooks for extra EVP features. This allows various cipher
5089 parameters to be set in the EVP interface. Support added for variable
5090 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
5091 setting of RC2 and RC5 parameters.
5093 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
5096 Remove lots of duplicated code from the EVP library. For example *every*
5097 cipher init() function handles the 'iv' in the same way according to the
5098 cipher mode. They also all do nothing if the 'key' parameter is NULL and
5099 for CFB and OFB modes they zero ctx->num.
5101 New functionality allows removal of S/MIME code RC2 hack.
5103 Most of the routines have the same form and so can be declared in terms
5106 By shifting this to the top level EVP_CipherInit() it can be removed from
5107 all individual ciphers. If the cipher wants to handle IVs or keys
5108 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
5111 Change lots of functions like EVP_EncryptUpdate() to now return a
5112 value: although software versions of the algorithms cannot fail
5113 any installed hardware versions can.
5116 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
5117 this option is set, tolerate broken clients that send the negotiated
5118 protocol version number instead of the requested protocol version
5122 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
5123 i.e. non-zero for export ciphersuites, zero otherwise.
5124 Previous versions had this flag inverted, inconsistent with
5125 rsa_tmp_cb (..._TMP_RSA_CB).
5126 [Bodo Moeller; problem reported by Amit Chopra]
5128 *) Add missing DSA library text string. Work around for some IIS
5129 key files with invalid SEQUENCE encoding.
5132 *) Add a document (doc/standards.txt) that list all kinds of standards
5133 and so on that are implemented in OpenSSL.
5136 *) Enhance c_rehash script. Old version would mishandle certificates
5137 with the same subject name hash and wouldn't handle CRLs at all.
5138 Added -fingerprint option to crl utility, to support new c_rehash
5142 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
5145 *) Fix for SSL server purpose checking. Server checking was
5146 rejecting certificates which had extended key usage present
5147 but no ssl client purpose.
5148 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
5150 *) Make PKCS#12 code work with no password. The PKCS#12 spec
5151 is a little unclear about how a blank password is handled.
5152 Since the password in encoded as a BMPString with terminating
5153 double NULL a zero length password would end up as just the
5154 double NULL. However no password at all is different and is
5155 handled differently in the PKCS#12 key generation code. NS
5156 treats a blank password as zero length. MSIE treats it as no
5157 password on export: but it will try both on import. We now do
5158 the same: PKCS12_parse() tries zero length and no password if
5159 the password is set to "" or NULL (NULL is now a valid password:
5160 it wasn't before) as does the pkcs12 application.
5163 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
5164 perror when PEM_read_bio_X509_REQ fails, the error message must
5165 be obtained from the error queue.
5168 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
5169 it in ERR_remove_state if appropriate, and change ERR_get_state
5170 accordingly to avoid race conditions (this is necessary because
5171 thread_hash is no longer constant once set).
5174 *) Bugfix for linux-elf makefile.one.
5177 *) RSA_get_default_method() will now cause a default
5178 RSA_METHOD to be chosen if one doesn't exist already.
5179 Previously this was only set during a call to RSA_new()
5180 or RSA_new_method(NULL) meaning it was possible for
5181 RSA_get_default_method() to return NULL.
5184 *) Added native name translation to the existing DSO code
5185 that will convert (if the flag to do so is set) filenames
5186 that are sufficiently small and have no path information
5187 into a canonical native form. Eg. "blah" converted to
5188 "libblah.so" or "blah.dll" etc.
5191 *) New function ERR_error_string_n(e, buf, len) which is like
5192 ERR_error_string(e, buf), but writes at most 'len' bytes
5193 including the 0 terminator. For ERR_error_string_n, 'buf'
5195 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
5197 *) CONF library reworked to become more general. A new CONF
5198 configuration file reader "class" is implemented as well as a
5199 new functions (NCONF_*, for "New CONF") to handle it. The now
5200 old CONF_* functions are still there, but are reimplemented to
5201 work in terms of the new functions. Also, a set of functions
5202 to handle the internal storage of the configuration data is
5203 provided to make it easier to write new configuration file
5204 reader "classes" (I can definitely see something reading a
5205 configuration file in XML format, for example), called _CONF_*,
5206 or "the configuration storage API"...
5208 The new configuration file reading functions are:
5210 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
5211 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
5213 NCONF_default, NCONF_WIN32
5215 NCONF_dump_fp, NCONF_dump_bio
5217 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
5218 NCONF_new creates a new CONF object. This works in the same way
5219 as other interfaces in OpenSSL, like the BIO interface.
5220 NCONF_dump_* dump the internal storage of the configuration file,
5221 which is useful for debugging. All other functions take the same
5222 arguments as the old CONF_* functions wth the exception of the
5223 first that must be a `CONF *' instead of a `LHASH *'.
5225 To make it easer to use the new classes with the old CONF_* functions,
5226 the function CONF_set_default_method is provided.
5229 *) Add '-tls1' option to 'openssl ciphers', which was already
5230 mentioned in the documentation but had not been implemented.
5231 (This option is not yet really useful because even the additional
5232 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
5235 *) Initial DSO code added into libcrypto for letting OpenSSL (and
5236 OpenSSL-based applications) load shared libraries and bind to
5237 them in a portable way.
5238 [Geoff Thorpe, with contributions from Richard Levitte]
5240 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
5242 *) Make sure _lrotl and _lrotr are only used with MSVC.
5244 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
5245 (the default implementation of RAND_status).
5247 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
5248 to '-clrext' (= clear extensions), as intended and documented.
5249 [Bodo Moeller; inconsistency pointed out by Michael Attili
5252 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
5253 was larger than the MD block size.
5254 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
5256 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
5257 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
5258 using the passed key: if the passed key was a private key the result
5259 of X509_print(), for example, would be to print out all the private key
5263 *) des_quad_cksum() byte order bug fix.
5264 [Ulf Möller, using the problem description in krb4-0.9.7, where
5265 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
5267 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
5269 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
5271 *) For easily testing in shell scripts whether some command
5272 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
5273 returns with exit code 0 iff no command of the given name is available.
5274 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
5275 the output goes to stdout and nothing is printed to stderr.
5276 Additional arguments are always ignored.
5278 Since for each cipher there is a command of the same name,
5279 the 'no-cipher' compilation switches can be tested this way.
5281 ('openssl no-XXX' is not able to detect pseudo-commands such
5282 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
5285 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
5288 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
5289 is set; it will be thrown away anyway because each handshake creates
5291 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
5292 to parameters -- in previous versions (since OpenSSL 0.9.3) the
5293 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
5294 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
5297 *) New s_client option -ign_eof: EOF at stdin is ignored, and
5298 'Q' and 'R' lose their special meanings (quit/renegotiate).
5299 This is part of what -quiet does; unlike -quiet, -ign_eof
5300 does not suppress any output.
5303 *) Add compatibility options to the purpose and trust code. The
5304 purpose X509_PURPOSE_ANY is "any purpose" which automatically
5305 accepts a certificate or CA, this was the previous behaviour,
5306 with all the associated security issues.
5308 X509_TRUST_COMPAT is the old trust behaviour: only and
5309 automatically trust self signed roots in certificate store. A
5310 new trust setting X509_TRUST_DEFAULT is used to specify that
5311 a purpose has no associated trust setting and it should instead
5312 use the value in the default purpose.
5315 *) Fix the PKCS#8 DSA private key code so it decodes keys again
5316 and fix a memory leak.
5319 *) In util/mkerr.pl (which implements 'make errors'), preserve
5320 reason strings from the previous version of the .c file, as
5321 the default to have only downcase letters (and digits) in
5322 automatically generated reasons codes is not always appropriate.
5325 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
5326 using strerror. Previously, ERR_reason_error_string() returned
5327 library names as reason strings for SYSerr; but SYSerr is a special
5328 case where small numbers are errno values, not library numbers.
5331 *) Add '-dsaparam' option to 'openssl dhparam' application. This
5332 converts DSA parameters into DH parameters. (When creating parameters,
5333 DSA_generate_parameters is used.)
5336 *) Include 'length' (recommended exponent length) in C code generated
5337 by 'openssl dhparam -C'.
5340 *) The second argument to set_label in perlasm was already being used
5341 so couldn't be used as a "file scope" flag. Moved to third argument
5345 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
5346 instead of RAND_bytes for encryption IVs and salts.
5349 *) Include RAND_status() into RAND_METHOD instead of implementing
5350 it only for md_rand.c Otherwise replacing the PRNG by calling
5351 RAND_set_rand_method would be impossible.
5354 *) Don't let DSA_generate_key() enter an infinite loop if the random
5355 number generation fails.
5358 *) New 'rand' application for creating pseudo-random output.
5361 *) Added configuration support for Linux/IA64
5362 [Rolf Haberrecker <rolf@suse.de>]
5364 *) Assembler module support for Mingw32.
5367 *) Shared library support for HPUX (in shlib/).
5368 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
5370 *) Shared library support for Solaris gcc.
5371 [Lutz Behnke <behnke@trustcenter.de>]
5373 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
5375 *) PKCS7_encrypt() was adding text MIME headers twice because they
5376 were added manually and by SMIME_crlf_copy().
5379 *) In bntest.c don't call BN_rand with zero bits argument.
5380 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
5382 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
5383 case was implemented. This caused BN_div_recp() to fail occasionally.
5386 *) Add an optional second argument to the set_label() in the perl
5387 assembly language builder. If this argument exists and is set
5388 to 1 it signals that the assembler should use a symbol whose
5389 scope is the entire file, not just the current function. This
5390 is needed with MASM which uses the format label:: for this scope.
5391 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
5393 *) Change the ASN1 types so they are typedefs by default. Before
5394 almost all types were #define'd to ASN1_STRING which was causing
5395 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
5399 *) Change names of new functions to the new get1/get0 naming
5400 convention: After 'get1', the caller owns a reference count
5401 and has to call ..._free; 'get0' returns a pointer to some
5402 data structure without incrementing reference counters.
5403 (Some of the existing 'get' functions increment a reference
5404 counter, some don't.)
5405 Similarly, 'set1' and 'add1' functions increase reference
5406 counters or duplicate objects.
5409 *) Allow for the possibility of temp RSA key generation failure:
5410 the code used to assume it always worked and crashed on failure.
5413 *) Fix potential buffer overrun problem in BIO_printf().
5414 [Ulf Möller, using public domain code by Patrick Powell; problem
5415 pointed out by David Sacerdote <das33@cornell.edu>]
5417 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
5418 RAND_egd() and RAND_status(). In the command line application,
5419 the EGD socket can be specified like a seed file using RANDFILE
5423 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
5424 Some CAs (e.g. Verisign) distribute certificates in this form.
5427 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
5428 list to exclude them. This means that no special compilation option
5429 is needed to use anonymous DH: it just needs to be included in the
5433 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
5434 EVP_MD_type. The old functionality is available in a new macro called
5435 EVP_MD_md(). Change code that uses it and update docs.
5438 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
5439 where the 'void *' argument is replaced by a function pointer argument.
5440 Previously 'void *' was abused to point to functions, which works on
5441 many platforms, but is not correct. As these functions are usually
5442 called by macros defined in OpenSSL header files, most source code
5443 should work without changes.
5446 *) <openssl/opensslconf.h> (which is created by Configure) now contains
5447 sections with information on -D... compiler switches used for
5448 compiling the library so that applications can see them. To enable
5449 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
5450 must be defined. E.g.,
5451 #define OPENSSL_ALGORITHM_DEFINES
5452 #include <openssl/opensslconf.h>
5453 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
5454 [Richard Levitte, Ulf and Bodo Möller]
5456 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
5460 *) Change the 'other' type in certificate aux info to a STACK_OF
5461 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
5462 the required ASN1 format: arbitrary types determined by an OID.
5465 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
5466 argument to 'req'. This is not because the function is newer or
5467 better than others it just uses the work 'NEW' in the certificate
5468 request header lines. Some software needs this.
5471 *) Reorganise password command line arguments: now passwords can be
5472 obtained from various sources. Delete the PEM_cb function and make
5473 it the default behaviour: i.e. if the callback is NULL and the
5474 usrdata argument is not NULL interpret it as a null terminated pass
5475 phrase. If usrdata and the callback are NULL then the pass phrase
5476 is prompted for as usual.
5479 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
5480 the support is automatically enabled. The resulting binaries will
5481 autodetect the card and use it if present.
5482 [Ben Laurie and Compaq Inc.]
5484 *) Work around for Netscape hang bug. This sends certificate request
5485 and server done in one record. Since this is perfectly legal in the
5486 SSL/TLS protocol it isn't a "bug" option and is on by default. See
5487 the bugs/SSLv3 entry for more info.
5490 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
5493 *) Add -rand argument to smime and pkcs12 applications and read/write
5497 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
5500 *) Add command line password options to the remaining applications.
5503 *) Bug fix for BN_div_recp() for numerators with an even number of
5507 *) More tests in bntest.c, and changed test_bn output.
5510 *) ./config recognizes MacOS X now.
5513 *) Bug fix for BN_div() when the first words of num and divsor are
5514 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
5517 *) Add support for various broken PKCS#8 formats, and command line
5518 options to produce them.
5521 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
5522 get temporary BIGNUMs from a BN_CTX.
5525 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
5529 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
5530 include a #define from the old name to the new. The original intent
5531 was that statically linked binaries could for example just call
5532 SSLeay_add_all_ciphers() to just add ciphers to the table and not
5533 link with digests. This never worked becayse SSLeay_add_all_digests()
5534 and SSLeay_add_all_ciphers() were in the same source file so calling
5535 one would link with the other. They are now in separate source files.
5538 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
5541 *) Use a less unusual form of the Miller-Rabin primality test (it used
5542 a binary algorithm for exponentiation integrated into the Miller-Rabin
5543 loop, our standard modexp algorithms are faster).
5546 *) Support for the EBCDIC character set completed.
5547 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
5549 *) Source code cleanups: use const where appropriate, eliminate casts,
5550 use void * instead of char * in lhash.
5553 *) Bugfix: ssl3_send_server_key_exchange was not restartable
5554 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
5555 this the server could overwrite ephemeral keys that the client
5559 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
5560 using 50 iterations of the Rabin-Miller test.
5562 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
5563 iterations of the Rabin-Miller test as required by the appendix
5564 to FIPS PUB 186[-1]) instead of DSA_is_prime.
5565 As BN_is_prime_fasttest includes trial division, DSA parameter
5566 generation becomes much faster.
5568 This implies a change for the callback functions in DSA_is_prime
5569 and DSA_generate_parameters: The callback function is called once
5570 for each positive witness in the Rabin-Miller test, not just
5571 occasionally in the inner loop; and the parameters to the
5572 callback function now provide an iteration count for the outer
5573 loop rather than for the current invocation of the inner loop.
5574 DSA_generate_parameters additionally can call the callback
5575 function with an 'iteration count' of -1, meaning that a
5576 candidate has passed the trial division test (when q is generated
5577 from an application-provided seed, trial division is skipped).
5580 *) New function BN_is_prime_fasttest that optionally does trial
5581 division before starting the Rabin-Miller test and has
5582 an additional BN_CTX * argument (whereas BN_is_prime always
5583 has to allocate at least one BN_CTX).
5584 'callback(1, -1, cb_arg)' is called when a number has passed the
5585 trial division stage.
5588 *) Fix for bug in CRL encoding. The validity dates weren't being handled
5592 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
5595 *) New function BN_pseudo_rand().
5598 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
5599 bignum version of BN_from_montgomery() with the working code from
5600 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
5604 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
5605 made it impossible to use the same SSL_SESSION data structure in
5606 SSL2 clients in multiple threads.
5609 *) The return value of RAND_load_file() no longer counts bytes obtained
5610 by stat(). RAND_load_file(..., -1) is new and uses the complete file
5611 to seed the PRNG (previously an explicit byte count was required).
5612 [Ulf Möller, Bodo Möller]
5614 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
5615 used (char *) instead of (void *) and had casts all over the place.
5618 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
5621 *) Retain source code compatibility for BN_prime_checks macro:
5622 BN_is_prime(..., BN_prime_checks, ...) now uses
5623 BN_prime_checks_for_size to determine the appropriate number of
5624 Rabin-Miller iterations.
5627 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
5628 DH_CHECK_P_NOT_SAFE_PRIME.
5629 (Check if this is true? OpenPGP calls them "strong".)
5632 *) Merge the functionality of "dh" and "gendh" programs into a new program
5633 "dhparam". The old programs are retained for now but will handle DH keys
5634 (instead of parameters) in future.
5637 *) Make the ciphers, s_server and s_client programs check the return values
5638 when a new cipher list is set.
5641 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
5642 ciphers. Before when the 56bit ciphers were enabled the sorting was
5645 The syntax for the cipher sorting has been extended to support sorting by
5646 cipher-strength (using the strength_bits hard coded in the tables).
5647 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
5649 Fix a bug in the cipher-command parser: when supplying a cipher command
5650 string with an "undefined" symbol (neither command nor alphanumeric
5651 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
5652 an error is flagged.
5654 Due to the strength-sorting extension, the code of the
5655 ssl_create_cipher_list() function was completely rearranged. I hope that
5656 the readability was also increased :-)
5657 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
5659 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
5660 for the first serial number and places 2 in the serial number file. This
5661 avoids problems when the root CA is created with serial number zero and
5662 the first user certificate has the same issuer name and serial number
5666 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
5667 the new code. Add documentation for this stuff.
5670 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
5671 X509_*() to X509at_*() on the grounds that they don't handle X509
5672 structures and behave in an analagous way to the X509v3 functions:
5673 they shouldn't be called directly but wrapper functions should be used
5676 So we also now have some wrapper functions that call the X509at functions
5677 when passed certificate requests. (TO DO: similar things can be done with
5678 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
5679 things. Some of these need some d2i or i2d and print functionality
5680 because they handle more complex structures.)
5683 *) Add missing #ifndefs that caused missing symbols when building libssl
5684 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
5685 NO_RSA in ssl/s2*.c.
5686 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
5688 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
5689 has a return value which indicates the quality of the random data
5690 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
5691 error queue. New function RAND_pseudo_bytes() generates output that is
5692 guaranteed to be unique but not unpredictable. RAND_add is like
5693 RAND_seed, but takes an extra argument for an entropy estimate
5694 (RAND_seed always assumes full entropy).
5697 *) Do more iterations of Rabin-Miller probable prime test (specifically,
5698 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
5699 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
5700 in crypto/bn/bn_prime.c for the complete table). This guarantees a
5701 false-positive rate of at most 2^-80 for random input.
5704 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
5707 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
5708 in the 0.9.5 release), this returns the chain
5709 from an X509_CTX structure with a dup of the stack and all
5710 the X509 reference counts upped: so the stack will exist
5711 after X509_CTX_cleanup() has been called. Modify pkcs12.c
5714 Also make SSL_SESSION_print() print out the verify return
5718 *) Add manpage for the pkcs12 command. Also change the default
5719 behaviour so MAC iteration counts are used unless the new
5720 -nomaciter option is used. This improves file security and
5721 only older versions of MSIE (4.0 for example) need it.
5724 *) Honor the no-xxx Configure options when creating .DEF files.
5727 *) Add PKCS#10 attributes to field table: challengePassword,
5728 unstructuredName and unstructuredAddress. These are taken from
5729 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
5730 international characters are used.
5732 More changes to X509_ATTRIBUTE code: allow the setting of types
5733 based on strings. Remove the 'loc' parameter when adding
5734 attributes because these will be a SET OF encoding which is sorted
5738 *) Initial changes to the 'req' utility to allow request generation
5739 automation. This will allow an application to just generate a template
5740 file containing all the field values and have req construct the
5743 Initial support for X509_ATTRIBUTE handling. Stacks of these are
5744 used all over the place including certificate requests and PKCS#7
5745 structures. They are currently handled manually where necessary with
5746 some primitive wrappers for PKCS#7. The new functions behave in a
5747 manner analogous to the X509 extension functions: they allow
5748 attributes to be looked up by NID and added.
5750 Later something similar to the X509V3 code would be desirable to
5751 automatically handle the encoding, decoding and printing of the
5752 more complex types. The string types like challengePassword can
5753 be handled by the string table functions.
5755 Also modified the multi byte string table handling. Now there is
5756 a 'global mask' which masks out certain types. The table itself
5757 can use the flag STABLE_NO_MASK to ignore the mask setting: this
5758 is useful when for example there is only one permissible type
5759 (as in countryName) and using the mask might result in no valid
5763 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
5764 SSL_get_peer_finished to allow applications to obtain the latest
5765 Finished messages sent to the peer or expected from the peer,
5766 respectively. (SSL_get_peer_finished is usually the Finished message
5767 actually received from the peer, otherwise the protocol will be aborted.)
5769 As the Finished message are message digests of the complete handshake
5770 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
5771 be used for external authentication procedures when the authentication
5772 provided by SSL/TLS is not desired or is not enough.
5775 *) Enhanced support for Alpha Linux is added. Now ./config checks if
5776 the host supports BWX extension and if Compaq C is present on the
5777 $PATH. Just exploiting of the BWX extension results in 20-30%
5778 performance kick for some algorithms, e.g. DES and RC4 to mention
5779 a couple. Compaq C in turn generates ~20% faster code for MD5 and
5783 *) Add support for MS "fast SGC". This is arguably a violation of the
5784 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
5785 weak crypto and after checking the certificate is SGC a second one
5786 with strong crypto. MS SGC stops the first handshake after receiving
5787 the server certificate message and sends a second client hello. Since
5788 a server will typically do all the time consuming operations before
5789 expecting any further messages from the client (server key exchange
5790 is the most expensive) there is little difference between the two.
5792 To get OpenSSL to support MS SGC we have to permit a second client
5793 hello message after we have sent server done. In addition we have to
5794 reset the MAC if we do get this second client hello.
5797 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
5798 if a DER encoded private key is RSA or DSA traditional format. Changed
5799 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
5800 format DER encoded private key. Newer code should use PKCS#8 format which
5801 has the key type encoded in the ASN1 structure. Added DER private key
5802 support to pkcs8 application.
5805 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
5806 ciphersuites has been selected (as required by the SSL 3/TLS 1
5807 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
5808 is set, we interpret this as a request to violate the specification
5809 (the worst that can happen is a handshake failure, and 'correct'
5810 behaviour would result in a handshake failure anyway).
5813 *) In SSL_CTX_add_session, take into account that there might be multiple
5814 SSL_SESSION structures with the same session ID (e.g. when two threads
5815 concurrently obtain them from an external cache).
5816 The internal cache can handle only one SSL_SESSION with a given ID,
5817 so if there's a conflict, we now throw out the old one to achieve
5821 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
5822 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
5823 some routines that use cipher OIDs: some ciphers do not have OIDs
5824 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
5828 *) Simplify the trust setting structure and code. Now we just have
5829 two sequences of OIDs for trusted and rejected settings. These will
5830 typically have values the same as the extended key usage extension
5831 and any application specific purposes.
5833 The trust checking code now has a default behaviour: it will just
5834 check for an object with the same NID as the passed id. Functions can
5835 be provided to override either the default behaviour or the behaviour
5836 for a given id. SSL client, server and email already have functions
5837 in place for compatibility: they check the NID and also return "trusted"
5838 if the certificate is self signed.
5841 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
5842 traditional format into an EVP_PKEY structure.
5845 *) Add a password callback function PEM_cb() which either prompts for
5846 a password if usr_data is NULL or otherwise assumes it is a null
5847 terminated password. Allow passwords to be passed on command line
5848 environment or config files in a few more utilities.
5851 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
5852 keys. Add some short names for PKCS#8 PBE algorithms and allow them
5853 to be specified on the command line for the pkcs8 and pkcs12 utilities.
5854 Update documentation.
5857 *) Support for ASN1 "NULL" type. This could be handled before by using
5858 ASN1_TYPE but there wasn't any function that would try to read a NULL
5859 and produce an error if it couldn't. For compatibility we also have
5860 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
5861 don't allocate anything because they don't need to.
5864 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
5866 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
5868 *) Rebuild of the memory allocation routines used by OpenSSL code and
5869 possibly others as well. The purpose is to make an interface that
5870 provide hooks so anyone can build a separate set of allocation and
5871 deallocation routines to be used by OpenSSL, for example memory
5872 pool implementations, or something else, which was previously hard
5873 since Malloc(), Realloc() and Free() were defined as macros having
5874 the values malloc, realloc and free, respectively (except for Win32
5875 compilations). The same is provided for memory debugging code.
5876 OpenSSL already comes with functionality to find memory leaks, but
5877 this gives people a chance to debug other memory problems.
5879 With these changes, a new set of functions and macros have appeared:
5881 CRYPTO_set_mem_debug_functions() [F]
5882 CRYPTO_get_mem_debug_functions() [F]
5883 CRYPTO_dbg_set_options() [F]
5884 CRYPTO_dbg_get_options() [F]
5885 CRYPTO_malloc_debug_init() [M]
5887 The memory debug functions are NULL by default, unless the library
5888 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
5889 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
5890 gives the standard debugging functions that come with OpenSSL) or
5891 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
5892 provided by the library user) must be used. When the standard
5893 debugging functions are used, CRYPTO_dbg_set_options can be used to
5894 request additional information:
5895 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
5896 the CRYPTO_MDEBUG_xxx macro when compiling the library.
5898 Also, things like CRYPTO_set_mem_functions will always give the
5899 expected result (the new set of functions is used for allocation
5900 and deallocation) at all times, regardless of platform and compiler
5903 To finish it up, some functions that were never use in any other
5904 way than through macros have a new API and new semantic:
5907 CRYPTO_dbg_realloc()
5910 All macros of value have retained their old syntax.
5911 [Richard Levitte and Bodo Moeller]
5913 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
5914 ordering of SMIMECapabilities wasn't in "strength order" and there
5915 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
5919 *) Some ASN1 types with illegal zero length encoding (INTEGER,
5920 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
5921 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
5923 *) Merge in my S/MIME library for OpenSSL. This provides a simple
5924 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
5925 functionality to handle multipart/signed properly) and a utility
5926 called 'smime' to call all this stuff. This is based on code I
5927 originally wrote for Celo who have kindly allowed it to be
5928 included in OpenSSL.
5931 *) Add variants des_set_key_checked and des_set_key_unchecked of
5932 des_set_key (aka des_key_sched). Global variable des_check_key
5933 decides which of these is called by des_set_key; this way
5934 des_check_key behaves as it always did, but applications and
5935 the library itself, which was buggy for des_check_key == 1,
5936 have a cleaner way to pick the version they need.
5939 *) New function PKCS12_newpass() which changes the password of a
5943 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
5944 dynamic mix. In both cases the ids can be used as an index into the
5945 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
5946 functions so they accept a list of the field values and the
5947 application doesn't need to directly manipulate the X509_TRUST
5951 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
5955 *) Modify the way the V3 extension code looks up extensions. This now
5956 works in a similar way to the object code: we have some "standard"
5957 extensions in a static table which is searched with OBJ_bsearch()
5958 and the application can add dynamic ones if needed. The file
5959 crypto/x509v3/ext_dat.h now has the info: this file needs to be
5960 updated whenever a new extension is added to the core code and kept
5961 in ext_nid order. There is a simple program 'tabtest.c' which checks
5962 this. New extensions are not added too often so this file can readily
5963 be maintained manually.
5965 There are two big advantages in doing things this way. The extensions
5966 can be looked up immediately and no longer need to be "added" using
5967 X509V3_add_standard_extensions(): this function now does nothing.
5968 [Side note: I get *lots* of email saying the extension code doesn't
5969 work because people forget to call this function]
5970 Also no dynamic allocation is done unless new extensions are added:
5971 so if we don't add custom extensions there is no need to call
5972 X509V3_EXT_cleanup().
5975 *) Modify enc utility's salting as follows: make salting the default. Add a
5976 magic header, so unsalted files fail gracefully instead of just decrypting
5977 to garbage. This is because not salting is a big security hole, so people
5978 should be discouraged from doing it.
5981 *) Fixes and enhancements to the 'x509' utility. It allowed a message
5982 digest to be passed on the command line but it only used this
5983 parameter when signing a certificate. Modified so all relevant
5984 operations are affected by the digest parameter including the
5985 -fingerprint and -x509toreq options. Also -x509toreq choked if a
5986 DSA key was used because it didn't fix the digest.
5989 *) Initial certificate chain verify code. Currently tests the untrusted
5990 certificates for consistency with the verify purpose (which is set
5991 when the X509_STORE_CTX structure is set up) and checks the pathlength.
5993 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
5994 this is because it will reject chains with invalid extensions whereas
5995 every previous version of OpenSSL and SSLeay made no checks at all.
5997 Trust code: checks the root CA for the relevant trust settings. Trust
5998 settings have an initial value consistent with the verify purpose: e.g.
5999 if the verify purpose is for SSL client use it expects the CA to be
6000 trusted for SSL client use. However the default value can be changed to
6001 permit custom trust settings: one example of this would be to only trust
6002 certificates from a specific "secure" set of CAs.
6004 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
6005 which should be used for version portability: especially since the
6006 verify structure is likely to change more often now.
6008 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
6009 to set them. If not set then assume SSL clients will verify SSL servers
6012 Two new options to the verify program: -untrusted allows a set of
6013 untrusted certificates to be passed in and -purpose which sets the
6014 intended purpose of the certificate. If a purpose is set then the
6015 new chain verify code is used to check extension consistency.
6018 *) Support for the authority information access extension.
6021 *) Modify RSA and DSA PEM read routines to transparently handle
6022 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
6023 public keys in a format compatible with certificate
6024 SubjectPublicKeyInfo structures. Unfortunately there were already
6025 functions called *_PublicKey_* which used various odd formats so
6026 these are retained for compatibility: however the DSA variants were
6027 never in a public release so they have been deleted. Changed dsa/rsa
6028 utilities to handle the new format: note no releases ever handled public
6029 keys so we should be OK.
6031 The primary motivation for this change is to avoid the same fiasco
6032 that dogs private keys: there are several incompatible private key
6033 formats some of which are standard and some OpenSSL specific and
6034 require various evil hacks to allow partial transparent handling and
6035 even then it doesn't work with DER formats. Given the option anything
6036 other than PKCS#8 should be dumped: but the other formats have to
6037 stay in the name of compatibility.
6039 With public keys and the benefit of hindsight one standard format
6040 is used which works with EVP_PKEY, RSA or DSA structures: though
6041 it clearly returns an error if you try to read the wrong kind of key.
6043 Added a -pubkey option to the 'x509' utility to output the public key.
6044 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
6045 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
6046 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
6047 that do the same as the EVP_PKEY_assign_*() except they up the
6048 reference count of the added key (they don't "swallow" the
6052 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
6053 CRLs would fail if the file contained no certificates or no CRLs:
6054 added a new function to read in both types and return the number
6055 read: this means that if none are read it will be an error. The
6056 DER versions of the certificate and CRL reader would always fail
6057 because it isn't possible to mix certificates and CRLs in DER format
6058 without choking one or the other routine. Changed this to just read
6059 a certificate: this is the best we can do. Also modified the code
6060 in apps/verify.c to take notice of return codes: it was previously
6061 attempting to read in certificates from NULL pointers and ignoring
6062 any errors: this is one reason why the cert and CRL reader seemed
6063 to work. It doesn't check return codes from the default certificate
6064 routines: these may well fail if the certificates aren't installed.
6067 *) Code to support otherName option in GeneralName.
6070 *) First update to verify code. Change the verify utility
6071 so it warns if it is passed a self signed certificate:
6072 for consistency with the normal behaviour. X509_verify
6073 has been modified to it will now verify a self signed
6074 certificate if *exactly* the same certificate appears
6075 in the store: it was previously impossible to trust a
6076 single self signed certificate. This means that:
6077 openssl verify ss.pem
6078 now gives a warning about a self signed certificate but
6079 openssl verify -CAfile ss.pem ss.pem
6083 *) For servers, store verify_result in SSL_SESSION data structure
6084 (and add it to external session representation).
6085 This is needed when client certificate verifications fails,
6086 but an application-provided verification callback (set by
6087 SSL_CTX_set_cert_verify_callback) allows accepting the session
6088 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
6089 but returns 1): When the session is reused, we have to set
6090 ssl->verify_result to the appropriate error code to avoid
6092 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
6094 *) Fix a bug in the new PKCS#7 code: it didn't consider the
6095 case in PKCS7_dataInit() where the signed PKCS7 structure
6096 didn't contain any existing data because it was being created.
6097 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
6099 *) Add a salt to the key derivation routines in enc.c. This
6100 forms the first 8 bytes of the encrypted file. Also add a
6101 -S option to allow a salt to be input on the command line.
6104 *) New function X509_cmp(). Oddly enough there wasn't a function
6105 to compare two certificates. We do this by working out the SHA1
6106 hash and comparing that. X509_cmp() will be needed by the trust
6110 *) SSL_get1_session() is like SSL_get_session(), but increments
6111 the reference count in the SSL_SESSION returned.
6112 [Geoff Thorpe <geoff@eu.c2.net>]
6114 *) Fix for 'req': it was adding a null to request attributes.
6115 Also change the X509_LOOKUP and X509_INFO code to handle
6116 certificate auxiliary information.
6119 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
6123 *) Add the possibility to add extra information to the memory leak
6124 detecting output, to form tracebacks, showing from where each
6125 allocation was originated: CRYPTO_push_info("constant string") adds
6126 the string plus current file name and line number to a per-thread
6127 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
6128 is like calling CYRPTO_pop_info() until the stack is empty.
6129 Also updated memory leak detection code to be multi-thread-safe.
6132 *) Add options -text and -noout to pkcs7 utility and delete the
6133 encryption options which never did anything. Update docs.
6136 *) Add options to some of the utilities to allow the pass phrase
6137 to be included on either the command line (not recommended on
6138 OSes like Unix) or read from the environment. Update the
6139 manpages and fix a few bugs.
6142 *) Add a few manpages for some of the openssl commands.
6145 *) Fix the -revoke option in ca. It was freeing up memory twice,
6146 leaking and not finding already revoked certificates.
6149 *) Extensive changes to support certificate auxiliary information.
6150 This involves the use of X509_CERT_AUX structure and X509_AUX
6151 functions. An X509_AUX function such as PEM_read_X509_AUX()
6152 can still read in a certificate file in the usual way but it
6153 will also read in any additional "auxiliary information". By
6154 doing things this way a fair degree of compatibility can be
6155 retained: existing certificates can have this information added
6156 using the new 'x509' options.
6158 Current auxiliary information includes an "alias" and some trust
6159 settings. The trust settings will ultimately be used in enhanced
6160 certificate chain verification routines: currently a certificate
6161 can only be trusted if it is self signed and then it is trusted
6165 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
6166 The problem was that one of the replacement routines had not been working
6167 since SSLeay releases. For now the offending routine has been replaced
6168 with non-optimised assembler. Even so, this now gives around 95%
6169 performance improvement for 1024 bit RSA signs.
6172 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
6173 handling. Most clients have the effective key size in bits equal to
6174 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
6175 A few however don't do this and instead use the size of the decrypted key
6176 to determine the RC2 key length and the AlgorithmIdentifier to determine
6177 the effective key length. In this case the effective key length can still
6178 be 40 bits but the key length can be 168 bits for example. This is fixed
6179 by manually forcing an RC2 key into the EVP_PKEY structure because the
6180 EVP code can't currently handle unusual RC2 key sizes: it always assumes
6181 the key length and effective key length are equal.
6184 *) Add a bunch of functions that should simplify the creation of
6185 X509_NAME structures. Now you should be able to do:
6186 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
6187 and have it automatically work out the correct field type and fill in
6188 the structures. The more adventurous can try:
6189 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
6190 and it will (hopefully) work out the correct multibyte encoding.
6193 *) Change the 'req' utility to use the new field handling and multibyte
6194 copy routines. Before the DN field creation was handled in an ad hoc
6195 way in req, ca, and x509 which was rather broken and didn't support
6196 BMPStrings or UTF8Strings. Since some software doesn't implement
6197 BMPStrings or UTF8Strings yet, they can be enabled using the config file
6198 using the dirstring_type option. See the new comment in the default
6199 openssl.cnf for more info.
6202 *) Make crypto/rand/md_rand.c more robust:
6203 - Assure unique random numbers after fork().
6204 - Make sure that concurrent threads access the global counter and
6205 md serializably so that we never lose entropy in them
6206 or use exactly the same state in multiple threads.
6207 Access to the large state is not always serializable because
6208 the additional locking could be a performance killer, and
6209 md should be large enough anyway.
6212 *) New file apps/app_rand.c with commonly needed functionality
6213 for handling the random seed file.
6215 Use the random seed file in some applications that previously did not:
6217 dsaparam -genkey (which also ignored its '-rand' option),
6220 x509 (when signing).
6221 Except on systems with /dev/urandom, it is crucial to have a random
6222 seed file at least for key creation, DSA signing, and for DH exchanges;
6223 for RSA signatures we could do without one.
6225 gendh and gendsa (unlike genrsa) used to read only the first byte
6226 of each file listed in the '-rand' option. The function as previously
6227 found in genrsa is now in app_rand.c and is used by all programs
6228 that support '-rand'.
6231 *) In RAND_write_file, use mode 0600 for creating files;
6232 don't just chmod when it may be too late.
6235 *) Report an error from X509_STORE_load_locations
6236 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
6239 *) New function ASN1_mbstring_copy() this copies a string in either
6240 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
6241 into an ASN1_STRING type. A mask of permissible types is passed
6242 and it chooses the "minimal" type to use or an error if not type
6246 *) Add function equivalents to the various macros in asn1.h. The old
6247 macros are retained with an M_ prefix. Code inside the library can
6248 use the M_ macros. External code (including the openssl utility)
6249 should *NOT* in order to be "shared library friendly".
6252 *) Add various functions that can check a certificate's extensions
6253 to see if it usable for various purposes such as SSL client,
6254 server or S/MIME and CAs of these types. This is currently
6255 VERY EXPERIMENTAL but will ultimately be used for certificate chain
6256 verification. Also added a -purpose flag to x509 utility to
6257 print out all the purposes.
6260 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
6264 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
6265 for, obtain and decode and extension and obtain its critical flag.
6266 This allows all the necessary extension code to be handled in a
6267 single function call.
6270 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
6271 platforms. See crypto/rc4/rc4_enc.c for further details.
6274 *) New -noout option to asn1parse. This causes no output to be produced
6275 its main use is when combined with -strparse and -out to extract data
6276 from a file (which may not be in ASN.1 format).
6279 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
6280 when producing the local key id.
6281 [Richard Levitte <levitte@stacken.kth.se>]
6283 *) New option -dhparam in s_server. This allows a DH parameter file to be
6284 stated explicitly. If it is not stated then it tries the first server
6285 certificate file. The previous behaviour hard coded the filename
6289 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
6290 a public key to be input or output. For example:
6291 openssl rsa -in key.pem -pubout -out pubkey.pem
6292 Also added necessary DSA public key functions to handle this.
6295 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
6296 in the message. This was handled by allowing
6297 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
6298 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
6300 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
6301 to the end of the strings whereas this didn't. This would cause problems
6302 if strings read with d2i_ASN1_bytes() were later modified.
6303 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
6305 *) Fix for base64 decode bug. When a base64 bio reads only one line of
6306 data and it contains EOF it will end up returning an error. This is
6307 caused by input 46 bytes long. The cause is due to the way base64
6308 BIOs find the start of base64 encoded data. They do this by trying a
6309 trial decode on each line until they find one that works. When they
6310 do a flag is set and it starts again knowing it can pass all the
6311 data directly through the decoder. Unfortunately it doesn't reset
6312 the context it uses. This means that if EOF is reached an attempt
6313 is made to pass two EOFs through the context and this causes the
6314 resulting error. This can also cause other problems as well. As is
6315 usual with these problems it takes *ages* to find and the fix is
6316 trivial: move one line.
6317 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
6319 *) Ugly workaround to get s_client and s_server working under Windows. The
6320 old code wouldn't work because it needed to select() on sockets and the
6321 tty (for keypresses and to see if data could be written). Win32 only
6322 supports select() on sockets so we select() with a 1s timeout on the
6323 sockets and then see if any characters are waiting to be read, if none
6324 are present then we retry, we also assume we can always write data to
6325 the tty. This isn't nice because the code then blocks until we've
6326 received a complete line of data and it is effectively polling the
6327 keyboard at 1s intervals: however it's quite a bit better than not
6328 working at all :-) A dedicated Windows application might handle this
6329 with an event loop for example.
6332 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
6333 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
6334 will be called when RSA_sign() and RSA_verify() are used. This is useful
6335 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
6336 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
6337 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
6338 This necessitated the support of an extra signature type NID_md5_sha1
6339 for SSL signatures and modifications to the SSL library to use it instead
6340 of calling RSA_public_decrypt() and RSA_private_encrypt().
6343 *) Add new -verify -CAfile and -CApath options to the crl program, these
6344 will lookup a CRL issuers certificate and verify the signature in a
6345 similar way to the verify program. Tidy up the crl program so it
6346 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
6347 less strict. It will now permit CRL extensions even if it is not
6348 a V2 CRL: this will allow it to tolerate some broken CRLs.
6351 *) Initialize all non-automatic variables each time one of the openssl
6352 sub-programs is started (this is necessary as they may be started
6353 multiple times from the "OpenSSL>" prompt).
6354 [Lennart Bang, Bodo Moeller]
6356 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
6357 removing all other RSA functionality (this is what NO_RSA does). This
6358 is so (for example) those in the US can disable those operations covered
6359 by the RSA patent while allowing storage and parsing of RSA keys and RSA
6363 *) Non-copying interface to BIO pairs.
6364 (still largely untested)
6367 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
6368 ASCII string. This was handled independently in various places before.
6371 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
6372 UTF8 strings a character at a time.
6375 *) Use client_version from client hello to select the protocol
6376 (s23_srvr.c) and for RSA client key exchange verification
6377 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
6380 *) Add various utility functions to handle SPKACs, these were previously
6381 handled by poking round in the structure internals. Added new function
6382 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
6383 print, verify and generate SPKACs. Based on an original idea from
6384 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
6387 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
6390 *) Allow the config file extension section to be overwritten on the
6391 command line. Based on an original idea from Massimiliano Pala
6392 <madwolf@comune.modena.it>. The new option is called -extensions
6393 and can be applied to ca, req and x509. Also -reqexts to override
6394 the request extensions in req and -crlexts to override the crl extensions
6398 *) Add new feature to the SPKAC handling in ca. Now you can include
6399 the same field multiple times by preceding it by "XXXX." for example:
6402 this is the same syntax as used in the req config file.
6405 *) Allow certificate extensions to be added to certificate requests. These
6406 are specified in a 'req_extensions' option of the req section of the
6407 config file. They can be printed out with the -text option to req but
6408 are otherwise ignored at present.
6411 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
6412 data read consists of only the final block it would not decrypted because
6413 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
6414 A misplaced 'break' also meant the decrypted final block might not be
6415 copied until the next read.
6418 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
6419 a few extra parameters to the DH structure: these will be useful if
6420 for example we want the value of 'q' or implement X9.42 DH.
6423 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
6424 provides hooks that allow the default DSA functions or functions on a
6425 "per key" basis to be replaced. This allows hardware acceleration and
6426 hardware key storage to be handled without major modification to the
6427 library. Also added low level modexp hooks and CRYPTO_EX structure and
6428 associated functions.
6431 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
6432 as "read only": it can't be written to and the buffer it points to will
6433 not be freed. Reading from a read only BIO is much more efficient than
6434 a normal memory BIO. This was added because there are several times when
6435 an area of memory needs to be read from a BIO. The previous method was
6436 to create a memory BIO and write the data to it, this results in two
6437 copies of the data and an O(n^2) reading algorithm. There is a new
6438 function BIO_new_mem_buf() which creates a read only memory BIO from
6439 an area of memory. Also modified the PKCS#7 routines to use read only
6443 *) Bugfix: ssl23_get_client_hello did not work properly when called in
6444 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
6445 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
6446 but a retry condition occured while trying to read the rest.
6449 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
6450 NID_pkcs7_encrypted by default: this was wrong since this should almost
6451 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
6452 the encrypted data type: this is a more sensible place to put it and it
6453 allows the PKCS#12 code to be tidied up that duplicated this
6457 *) Changed obj_dat.pl script so it takes its input and output files on
6458 the command line. This should avoid shell escape redirection problems
6462 *) Initial support for certificate extension requests, these are included
6463 in things like Xenroll certificate requests. Included functions to allow
6464 extensions to be obtained and added.
6467 *) -crlf option to s_client and s_server for sending newlines as
6468 CRLF (as required by many protocols).
6471 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
6473 *) Install libRSAglue.a when OpenSSL is built with RSAref.
6474 [Ralf S. Engelschall]
6476 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
6477 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
6479 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
6483 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
6484 DH parameters/keys (q is lost during that conversion, but the resulting
6485 DH parameters contain its length).
6487 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
6488 much faster than DH_generate_parameters (which creates parameters
6489 where p = 2*q + 1), and also the smaller q makes DH computations
6490 much more efficient (160-bit exponentiation instead of 1024-bit
6491 exponentiation); so this provides a convenient way to support DHE
6492 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
6493 utter importance to use
6494 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
6496 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
6497 when such DH parameters are used, because otherwise small subgroup
6498 attacks may become possible!
6501 *) Avoid memory leak in i2d_DHparams.
6504 *) Allow the -k option to be used more than once in the enc program:
6505 this allows the same encrypted message to be read by multiple recipients.
6508 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
6509 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
6510 it will always use the numerical form of the OID, even if it has a short
6514 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
6515 method only got called if p,q,dmp1,dmq1,iqmp components were present,
6516 otherwise bn_mod_exp was called. In the case of hardware keys for example
6517 no private key components need be present and it might store extra data
6518 in the RSA structure, which cannot be accessed from bn_mod_exp.
6519 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
6520 private key operations.
6523 *) Added support for SPARC Linux.
6526 *) pem_password_cb function type incompatibly changed from
6527 typedef int pem_password_cb(char *buf, int size, int rwflag);
6529 ....(char *buf, int size, int rwflag, void *userdata);
6530 so that applications can pass data to their callbacks:
6531 The PEM[_ASN1]_{read,write}... functions and macros now take an
6532 additional void * argument, which is just handed through whenever
6533 the password callback is called.
6534 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
6536 New function SSL_CTX_set_default_passwd_cb_userdata.
6538 Compatibility note: As many C implementations push function arguments
6539 onto the stack in reverse order, the new library version is likely to
6540 interoperate with programs that have been compiled with the old
6541 pem_password_cb definition (PEM_whatever takes some data that
6542 happens to be on the stack as its last argument, and the callback
6543 just ignores this garbage); but there is no guarantee whatsoever that
6546 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
6547 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
6548 problems not only on Windows, but also on some Unix platforms.
6549 To avoid problematic command lines, these definitions are now in an
6550 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
6551 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
6554 *) MIPS III/IV assembler module is reimplemented.
6557 *) More DES library cleanups: remove references to srand/rand and
6558 delete an unused file.
6561 *) Add support for the the free Netwide assembler (NASM) under Win32,
6562 since not many people have MASM (ml) and it can be hard to obtain.
6563 This is currently experimental but it seems to work OK and pass all
6564 the tests. Check out INSTALL.W32 for info.
6567 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
6568 without temporary keys kept an extra copy of the server key,
6569 and connections with temporary keys did not free everything in case
6573 *) New function RSA_check_key and new openssl rsa option -check
6574 for verifying the consistency of RSA keys.
6575 [Ulf Moeller, Bodo Moeller]
6577 *) Various changes to make Win32 compile work:
6578 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
6579 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
6580 comparison" warnings.
6581 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
6584 *) Add a debugging option to PKCS#5 v2 key generation function: when
6585 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
6586 derived keys are printed to stderr.
6589 *) Copy the flags in ASN1_STRING_dup().
6590 [Roman E. Pavlov <pre@mo.msk.ru>]
6592 *) The x509 application mishandled signing requests containing DSA
6593 keys when the signing key was also DSA and the parameters didn't match.
6595 It was supposed to omit the parameters when they matched the signing key:
6596 the verifying software was then supposed to automatically use the CA's
6597 parameters if they were absent from the end user certificate.
6599 Omitting parameters is no longer recommended. The test was also
6600 the wrong way round! This was probably due to unusual behaviour in
6601 EVP_cmp_parameters() which returns 1 if the parameters match.
6602 This meant that parameters were omitted when they *didn't* match and
6603 the certificate was useless. Certificates signed with 'ca' didn't have
6605 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
6607 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
6608 The interface is as follows:
6609 Applications can use
6610 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
6611 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
6612 "off" is now the default.
6613 The library internally uses
6614 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
6615 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
6616 to disable memory-checking temporarily.
6618 Some inconsistent states that previously were possible (and were
6619 even the default) are now avoided.
6621 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
6622 with each memory chunk allocated; this is occasionally more helpful
6623 than just having a counter.
6625 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
6627 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
6631 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
6632 which largely parallels "options", but is for changing API behaviour,
6633 whereas "options" are about protocol behaviour.
6634 Initial "mode" flags are:
6636 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
6637 a single record has been written.
6638 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
6639 retries use the same buffer location.
6640 (But all of the contents must be
6644 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
6647 *) Fix problems with no-hmac etc.
6648 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
6650 *) New functions RSA_get_default_method(), RSA_set_method() and
6651 RSA_get_method(). These allows replacement of RSA_METHODs without having
6652 to mess around with the internals of an RSA structure.
6655 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
6656 Also really enable memory leak checks in openssl.c and in some
6658 [Chad C. Mulligan, Bodo Moeller]
6660 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
6661 up the length of negative integers. This has now been simplified to just
6662 store the length when it is first determined and use it later, rather
6663 than trying to keep track of where data is copied and updating it to
6665 [Steve Henson, reported by Brien Wheeler
6666 <bwheeler@authentica-security.com>]
6668 *) Add a new function PKCS7_signatureVerify. This allows the verification
6669 of a PKCS#7 signature but with the signing certificate passed to the
6670 function itself. This contrasts with PKCS7_dataVerify which assumes the
6671 certificate is present in the PKCS#7 structure. This isn't always the
6672 case: certificates can be omitted from a PKCS#7 structure and be
6673 distributed by "out of band" means (such as a certificate database).
6676 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
6677 function prototypes in pem.h, also change util/mkdef.pl to add the
6678 necessary function names.
6681 *) mk1mf.pl (used by Windows builds) did not properly read the
6682 options set by Configure in the top level Makefile, and Configure
6683 was not even able to write more than one option correctly.
6684 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
6687 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
6688 file to be loaded from a BIO or FILE pointer. The BIO version will
6689 for example allow memory BIOs to contain config info.
6692 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
6693 Whoever hopes to achieve shared-library compatibility across versions
6694 must use this, not the compile-time macro.
6695 (Exercise 0.9.4: Which is the minimum library version required by
6697 Note: All this applies only to multi-threaded programs, others don't
6701 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
6702 through a BIO pair triggered the default case, i.e.
6703 SSLerr(...,SSL_R_UNKNOWN_STATE).
6706 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
6707 can use the SSL library even if none of the specific BIOs is
6711 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
6712 for the encoded length.
6713 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
6715 *) Add initial documentation of the X509V3 functions.
6718 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
6719 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
6720 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
6721 secure PKCS#8 private key format with a high iteration count.
6724 *) Fix determination of Perl interpreter: A perl or perl5
6725 _directory_ in $PATH was also accepted as the interpreter.
6726 [Ralf S. Engelschall]
6728 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
6729 wrong with it but it was very old and did things like calling
6730 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
6734 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
6735 to use the new extension code.
6738 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
6739 with macros. This should make it easier to change their form, add extra
6740 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
6744 *) Add to configuration table a new entry that can specify an alternative
6745 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
6746 according to Mark Crispin <MRC@Panda.COM>.
6750 *) DES CBC did not update the IV. Weird.
6753 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
6754 Changing the behaviour of the former might break existing programs --
6755 where IV updating is needed, des_ncbc_encrypt can be used.
6758 *) When bntest is run from "make test" it drives bc to check its
6759 calculations, as well as internally checking them. If an internal check
6760 fails, it needs to cause bc to give a non-zero result or make test carries
6761 on without noticing the failure. Fixed.
6764 *) DES library cleanups.
6767 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
6768 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
6769 ciphers. NOTE: although the key derivation function has been verified
6770 against some published test vectors it has not been extensively tested
6771 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
6775 *) Instead of "mkdir -p", which is not fully portable, use new
6776 Perl script "util/mkdir-p.pl".
6779 *) Rewrite the way password based encryption (PBE) is handled. It used to
6780 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
6781 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
6782 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
6783 the 'parameter' field of the AlgorithmIdentifier is passed to the
6784 underlying key generation function so it must do its own ASN1 parsing.
6785 This has also changed the EVP_PBE_CipherInit() function which now has a
6786 'parameter' argument instead of literal salt and iteration count values
6787 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
6790 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
6791 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
6792 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
6793 KEY" because this clashed with PKCS#8 unencrypted string. Since this
6794 value was just used as a "magic string" and not used directly its
6795 value doesn't matter.
6798 *) Introduce some semblance of const correctness to BN. Shame C doesn't
6802 *) "linux-sparc64" configuration (ultrapenguin).
6803 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
6804 "linux-sparc" configuration.
6805 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
6807 *) config now generates no-xxx options for missing ciphers.
6810 *) Support the EBCDIC character set (work in progress).
6811 File ebcdic.c not yet included because it has a different license.
6812 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
6814 *) Support BS2000/OSD-POSIX.
6815 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
6817 *) Make callbacks for key generation use void * instead of char *.
6820 *) Make S/MIME samples compile (not yet tested).
6823 *) Additional typesafe stacks.
6826 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
6830 Changes between 0.9.3 and 0.9.3a [29 May 1999]
6832 *) New configuration variant "sco5-gcc".
6834 *) Updated some demos.
6835 [Sean O Riordain, Wade Scholine]
6837 *) Add missing BIO_free at exit of pkcs12 application.
6840 *) Fix memory leak in conf.c.
6843 *) Updates for Win32 to assembler version of MD5.
6846 *) Set #! path to perl in apps/der_chop to where we found it
6847 instead of using a fixed path.
6850 *) SHA library changes for irix64-mips4-cc.
6853 *) Improvements for VMS support.
6857 Changes between 0.9.2b and 0.9.3 [24 May 1999]
6859 *) Bignum library bug fix. IRIX 6 passes "make test" now!
6860 This also avoids the problems with SC4.2 and unpatched SC5.
6861 [Andy Polyakov <appro@fy.chalmers.se>]
6863 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
6864 These are required because of the typesafe stack would otherwise break
6865 existing code. If old code used a structure member which used to be STACK
6866 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
6867 sk_num or sk_value it would produce an error because the num, data members
6868 are not present in STACK_OF. Now it just produces a warning. sk_set
6869 replaces the old method of assigning a value to sk_value
6870 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
6871 that does this will no longer work (and should use sk_set instead) but
6872 this could be regarded as a "questionable" behaviour anyway.
6875 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
6876 correctly handle encrypted S/MIME data.
6879 *) Change type of various DES function arguments from des_cblock
6880 (which means, in function argument declarations, pointer to char)
6881 to des_cblock * (meaning pointer to array with 8 char elements),
6882 which allows the compiler to do more typechecking; it was like
6883 that back in SSLeay, but with lots of ugly casts.
6885 Introduce new type const_des_cblock.
6888 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
6889 problems: find RecipientInfo structure that matches recipient certificate
6890 and initialise the ASN1 structures properly based on passed cipher.
6893 *) Belatedly make the BN tests actually check the results.
6896 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
6897 to and from BNs: it was completely broken. New compilation option
6898 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
6899 key elements as negative integers.
6902 *) Reorganize and speed up MD5.
6903 [Andy Polyakov <appro@fy.chalmers.se>]
6906 [Richard Levitte <richard@levitte.org>]
6908 *) New option -out to asn1parse to allow the parsed structure to be
6909 output to a file. This is most useful when combined with the -strparse
6910 option to examine the output of things like OCTET STRINGS.
6913 *) Make SSL library a little more fool-proof by not requiring any longer
6914 that SSL_set_{accept,connect}_state be called before
6915 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
6916 in many applications because usually everything *appeared* to work as
6917 intended anyway -- now it really works as intended).
6920 *) Move openssl.cnf out of lib/.
6923 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
6924 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
6925 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
6926 [Ralf S. Engelschall]
6928 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
6929 handle PKCS#7 enveloped data properly.
6930 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
6932 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
6933 copying pointers. The cert_st handling is changed by this in
6934 various ways (and thus what used to be known as ctx->default_cert
6935 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
6936 any longer when s->cert does not give us what we need).
6937 ssl_cert_instantiate becomes obsolete by this change.
6938 As soon as we've got the new code right (possibly it already is?),
6939 we have solved a couple of bugs of the earlier code where s->cert
6940 was used as if it could not have been shared with other SSL structures.
6942 Note that using the SSL API in certain dirty ways now will result
6943 in different behaviour than observed with earlier library versions:
6944 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
6945 does not influence s as it used to.
6947 In order to clean up things more thoroughly, inside SSL_SESSION
6948 we don't use CERT any longer, but a new structure SESS_CERT
6949 that holds per-session data (if available); currently, this is
6950 the peer's certificate chain and, for clients, the server's certificate
6951 and temporary key. CERT holds only those values that can have
6952 meaningful defaults in an SSL_CTX.
6955 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
6956 from the internal representation. Various PKCS#7 fixes: remove some
6957 evil casts and set the enc_dig_alg field properly based on the signing
6961 *) Allow PKCS#12 password to be set from the command line or the
6962 environment. Let 'ca' get its config file name from the environment
6963 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
6967 *) Allow certificate policies extension to use an IA5STRING for the
6968 organization field. This is contrary to the PKIX definition but
6969 VeriSign uses it and IE5 only recognises this form. Document 'x509'
6973 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
6974 without disallowing inline assembler and the like for non-pedantic builds.
6977 *) Support Borland C++ builder.
6978 [Janez Jere <jj@void.si>, modified by Ulf Möller]
6983 *) SHA-1 cleanups and performance enhancements.
6984 [Andy Polyakov <appro@fy.chalmers.se>]
6986 *) Sparc v8plus assembler for the bignum library.
6987 [Andy Polyakov <appro@fy.chalmers.se>]
6989 *) Accept any -xxx and +xxx compiler options in Configure.
6992 *) Update HPUX configuration.
6995 *) Add missing sk_<type>_unshift() function to safestack.h
6996 [Ralf S. Engelschall]
6998 *) New function SSL_CTX_use_certificate_chain_file that sets the
6999 "extra_cert"s in addition to the certificate. (This makes sense
7000 only for "PEM" format files, as chains as a whole are not
7004 *) Support verify_depth from the SSL API.
7005 x509_vfy.c had what can be considered an off-by-one-error:
7006 Its depth (which was not part of the external interface)
7007 was actually counting the number of certificates in a chain;
7008 now it really counts the depth.
7011 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
7012 instead of X509err, which often resulted in confusing error
7013 messages since the error codes are not globally unique
7014 (e.g. an alleged error in ssl3_accept when a certificate
7015 didn't match the private key).
7017 *) New function SSL_CTX_set_session_id_context that allows to set a default
7018 value (so that you don't need SSL_set_session_id_context for each
7019 connection using the SSL_CTX).
7022 *) OAEP decoding bug fix.
7025 *) Support INSTALL_PREFIX for package builders, as proposed by
7029 *) New Configure options "threads" and "no-threads". For systems
7030 where the proper compiler options are known (currently Solaris
7031 and Linux), "threads" is the default.
7034 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
7037 *) Install various scripts to $(OPENSSLDIR)/misc, not to
7038 $(INSTALLTOP)/bin -- they shouldn't clutter directories
7039 such as /usr/local/bin.
7042 *) "make linux-shared" to build shared libraries.
7043 [Niels Poppe <niels@netbox.org>]
7045 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
7048 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
7049 extension adding in x509 utility.
7052 *) Remove NOPROTO sections and error code comments.
7055 *) Partial rewrite of the DEF file generator to now parse the ANSI
7059 *) New Configure options --prefix=DIR and --openssldir=DIR.
7062 *) Complete rewrite of the error code script(s). It is all now handled
7063 by one script at the top level which handles error code gathering,
7064 header rewriting and C source file generation. It should be much better
7065 than the old method: it now uses a modified version of Ulf's parser to
7066 read the ANSI prototypes in all header files (thus the old K&R definitions
7067 aren't needed for error creation any more) and do a better job of
7068 translating function codes into names. The old 'ASN1 error code imbedded
7069 in a comment' is no longer necessary and it doesn't use .err files which
7070 have now been deleted. Also the error code call doesn't have to appear all
7071 on one line (which resulted in some large lines...).
7074 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
7077 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
7078 0 (which usually indicates a closed connection), but continue reading.
7081 *) Fix some race conditions.
7084 *) Add support for CRL distribution points extension. Add Certificate
7085 Policies and CRL distribution points documentation.
7088 *) Move the autogenerated header file parts to crypto/opensslconf.h.
7091 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
7092 8 of keying material. Merlin has also confirmed interop with this fix
7093 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
7094 [Merlin Hughes <merlin@baltimore.ie>]
7096 *) Fix lots of warnings.
7097 [Richard Levitte <levitte@stacken.kth.se>]
7099 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
7100 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
7101 [Richard Levitte <levitte@stacken.kth.se>]
7103 *) Fix problems with sizeof(long) == 8.
7104 [Andy Polyakov <appro@fy.chalmers.se>]
7106 *) Change functions to ANSI C.
7109 *) Fix typos in error codes.
7110 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
7112 *) Remove defunct assembler files from Configure.
7115 *) SPARC v8 assembler BIGNUM implementation.
7116 [Andy Polyakov <appro@fy.chalmers.se>]
7118 *) Support for Certificate Policies extension: both print and set.
7119 Various additions to support the r2i method this uses.
7122 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
7123 return a const string when you are expecting an allocated buffer.
7126 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
7127 types DirectoryString and DisplayText.
7130 *) Add code to allow r2i extensions to access the configuration database,
7131 add an LHASH database driver and add several ctx helper functions.
7134 *) Fix an evil bug in bn_expand2() which caused various BN functions to
7135 fail when they extended the size of a BIGNUM.
7138 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
7139 support typesafe stack.
7142 *) Fix typo in SSL_[gs]et_options().
7143 [Nils Frostberg <nils@medcom.se>]
7145 *) Delete various functions and files that belonged to the (now obsolete)
7146 old X509V3 handling code.
7149 *) New Configure option "rsaref".
7152 *) Don't auto-generate pem.h.
7155 *) Introduce type-safe ASN.1 SETs.
7158 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
7159 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
7161 *) Introduce type-safe STACKs. This will almost certainly break lots of code
7162 that links with OpenSSL (well at least cause lots of warnings), but fear
7163 not: the conversion is trivial, and it eliminates loads of evil casts. A
7164 few STACKed things have been converted already. Feel free to convert more.
7165 In the fullness of time, I'll do away with the STACK type altogether.
7168 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
7169 specified in <certfile> by updating the entry in the index.txt file.
7170 This way one no longer has to edit the index.txt file manually for
7171 revoking a certificate. The -revoke option does the gory details now.
7172 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
7174 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
7175 `-text' option at all and this way the `-noout -text' combination was
7176 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
7177 [Ralf S. Engelschall]
7179 *) Make sure a corresponding plain text error message exists for the
7180 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
7181 verify callback function determined that a certificate was revoked.
7182 [Ralf S. Engelschall]
7184 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
7185 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
7186 all available cipers including rc5, which was forgotten until now.
7187 In order to let the testing shell script know which algorithms
7188 are available, a new (up to now undocumented) command
7189 "openssl list-cipher-commands" is used.
7192 *) Bugfix: s_client occasionally would sleep in select() when
7193 it should have checked SSL_pending() first.
7196 *) New functions DSA_do_sign and DSA_do_verify to provide access to
7197 the raw DSA values prior to ASN.1 encoding.
7200 *) Tweaks to Configure
7201 [Niels Poppe <niels@netbox.org>]
7203 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
7207 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
7210 *) New config option to avoid instructions that are illegal on the 80386.
7211 The default code is faster, but requires at least a 486.
7214 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
7215 SSL2_SERVER_VERSION (not used at all) macros, which are now the
7216 same as SSL2_VERSION anyway.
7219 *) New "-showcerts" option for s_client.
7222 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
7223 application. Various cleanups and fixes.
7226 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
7227 modify error routines to work internally. Add error codes and PBE init
7228 to library startup routines.
7231 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
7232 packing functions to asn1 and evp. Changed function names and error
7233 codes along the way.
7236 *) PKCS12 integration: and so it begins... First of several patches to
7237 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
7238 objects to objects.h
7241 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
7242 and display support for Thawte strong extranet extension.
7245 *) Add LinuxPPC support.
7246 [Jeff Dubrule <igor@pobox.org>]
7248 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
7249 bn_div_words in alpha.s.
7250 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
7252 *) Make sure the RSA OAEP test is skipped under -DRSAref because
7253 OAEP isn't supported when OpenSSL is built with RSAref.
7254 [Ulf Moeller <ulf@fitug.de>]
7256 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
7257 so they no longer are missing under -DNOPROTO.
7258 [Soren S. Jorvang <soren@t.dk>]
7261 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
7263 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
7264 doesn't work when the session is reused. Coming soon!
7267 *) Fix a security hole, that allows sessions to be reused in the wrong
7268 context thus bypassing client cert protection! All software that uses
7269 client certs and session caches in multiple contexts NEEDS PATCHING to
7270 allow session reuse! A fuller solution is in the works.
7271 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
7273 *) Some more source tree cleanups (removed obsolete files
7274 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
7275 permission on "config" script to be executable) and a fix for the INSTALL
7277 [Ulf Moeller <ulf@fitug.de>]
7279 *) Remove some legacy and erroneous uses of malloc, free instead of
7281 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
7283 *) Make rsa_oaep_test return non-zero on error.
7284 [Ulf Moeller <ulf@fitug.de>]
7286 *) Add support for native Solaris shared libraries. Configure
7287 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
7288 if someone would make that last step automatic.
7289 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
7291 *) ctx_size was not built with the right compiler during "make links". Fixed.
7294 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
7295 except NULL ciphers". This means the default cipher list will no longer
7296 enable NULL ciphers. They need to be specifically enabled e.g. with
7297 the string "DEFAULT:eNULL".
7300 *) Fix to RSA private encryption routines: if p < q then it would
7301 occasionally produce an invalid result. This will only happen with
7302 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
7305 *) Be less restrictive and allow also `perl util/perlpath.pl
7306 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
7307 because this way one can also use an interpreter named `perl5' (which is
7308 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
7309 installed as `perl').
7310 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
7312 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
7313 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
7315 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
7316 advapi32.lib to Win32 build and change the pem test comparision
7317 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
7318 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
7319 and crypto/des/ede_cbcm_enc.c.
7322 *) DES quad checksum was broken on big-endian architectures. Fixed.
7325 *) Comment out two functions in bio.h that aren't implemented. Fix up the
7326 Win32 test batch file so it (might) work again. The Win32 test batch file
7327 is horrible: I feel ill....
7330 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
7331 in e_os.h. Audit of header files to check ANSI and non ANSI
7332 sections: 10 functions were absent from non ANSI section and not exported
7333 from Windows DLLs. Fixed up libeay.num for new functions.
7336 *) Make `openssl version' output lines consistent.
7337 [Ralf S. Engelschall]
7339 *) Fix Win32 symbol export lists for BIO functions: Added
7340 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
7341 to ms/libeay{16,32}.def.
7342 [Ralf S. Engelschall]
7344 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
7345 fine under Unix and passes some trivial tests I've now added. But the
7346 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
7347 added to make sure no one expects that this stuff really works in the
7348 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
7349 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
7351 [Ralf S. Engelschall]
7353 *) Fix the generation of two part addresses in perl.
7354 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
7356 *) Add config entry for Linux on MIPS.
7357 [John Tobey <jtobey@channel1.com>]
7359 *) Make links whenever Configure is run, unless we are on Windoze.
7362 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
7363 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
7367 *) Add a useful kludge to allow package maintainers to specify compiler and
7368 other platforms details on the command line without having to patch the
7369 Configure script everytime: One now can use ``perl Configure
7370 <id>:<details>'', i.e. platform ids are allowed to have details appended
7371 to them (seperated by colons). This is treated as there would be a static
7372 pre-configured entry in Configure's %table under key <id> with value
7373 <details> and ``perl Configure <id>'' is called. So, when you want to
7374 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
7375 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
7376 now, which overrides the FreeBSD-elf entry on-the-fly.
7377 [Ralf S. Engelschall]
7379 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
7382 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
7383 on the `perl Configure ...' command line. This way one can compile
7384 OpenSSL libraries with Position Independent Code (PIC) which is needed
7385 for linking it into DSOs.
7386 [Ralf S. Engelschall]
7388 *) Remarkably, export ciphers were totally broken and no-one had noticed!
7392 *) Cleaned up the LICENSE document: The official contact for any license
7393 questions now is the OpenSSL core team under openssl-core@openssl.org.
7394 And add a paragraph about the dual-license situation to make sure people
7395 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
7396 to the OpenSSL toolkit.
7397 [Ralf S. Engelschall]
7399 *) General source tree makefile cleanups: Made `making xxx in yyy...'
7400 display consistent in the source tree and replaced `/bin/rm' by `rm'.
7401 Additonally cleaned up the `make links' target: Remove unnecessary
7402 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
7403 to speed processing and no longer clutter the display with confusing
7404 stuff. Instead only the actually done links are displayed.
7405 [Ralf S. Engelschall]
7407 *) Permit null encryption ciphersuites, used for authentication only. It used
7408 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
7409 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
7413 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
7414 signed attributes when verifying signatures (this would break them),
7415 the detached data encoding was wrong and public keys obtained using
7416 X509_get_pubkey() weren't freed.
7419 *) Add text documentation for the BUFFER functions. Also added a work around
7420 to a Win95 console bug. This was triggered by the password read stuff: the
7421 last character typed gets carried over to the next fread(). If you were
7422 generating a new cert request using 'req' for example then the last
7423 character of the passphrase would be CR which would then enter the first
7427 *) Added the new `Includes OpenSSL Cryptography Software' button as
7428 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
7429 button and can be used by applications based on OpenSSL to show the
7430 relationship to the OpenSSL project.
7431 [Ralf S. Engelschall]
7433 *) Remove confusing variables in function signatures in files
7434 ssl/ssl_lib.c and ssl/ssl.h.
7435 [Lennart Bong <lob@kulthea.stacken.kth.se>]
7437 *) Don't install bss_file.c under PREFIX/include/
7438 [Lennart Bong <lob@kulthea.stacken.kth.se>]
7440 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
7441 functions that return function pointers and has support for NT specific
7442 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
7443 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
7444 unsigned to signed types: this was killing the Win32 compile.
7447 *) Add new certificate file to stack functions,
7448 SSL_add_dir_cert_subjects_to_stack() and
7449 SSL_add_file_cert_subjects_to_stack(). These largely supplant
7450 SSL_load_client_CA_file(), and can be used to add multiple certs easily
7451 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
7452 This means that Apache-SSL and similar packages don't have to mess around
7453 to add as many CAs as they want to the preferred list.
7456 *) Experiment with doxygen documentation. Currently only partially applied to
7458 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
7459 openssl.doxy as the configuration file.
7462 *) Get rid of remaining C++-style comments which strict C compilers hate.
7463 [Ralf S. Engelschall, pointed out by Carlos Amengual]
7465 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
7466 compiled in by default: it has problems with large keys.
7469 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
7470 DH private keys and/or callback functions which directly correspond to
7471 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
7472 is needed for applications which have to configure certificates on a
7473 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
7475 For the RSA certificate situation is makes no difference, but
7476 for the DSA certificate situation this fixes the "no shared cipher"
7477 problem where the OpenSSL cipher selection procedure failed because the
7478 temporary keys were not overtaken from the context and the API provided
7479 no way to reconfigure them.
7480 The new functions now let applications reconfigure the stuff and they
7481 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
7482 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
7483 non-public-API function ssl_cert_instantiate() is used as a helper
7484 function and also to reduce code redundancy inside ssl_rsa.c.
7485 [Ralf S. Engelschall]
7487 *) Move s_server -dcert and -dkey options out of the undocumented feature
7488 area because they are useful for the DSA situation and should be
7489 recognized by the users.
7490 [Ralf S. Engelschall]
7492 *) Fix the cipher decision scheme for export ciphers: the export bits are
7493 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
7494 SSL_EXP_MASK. So, the original variable has to be used instead of the
7495 already masked variable.
7496 [Richard Levitte <levitte@stacken.kth.se>]
7498 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
7499 [Richard Levitte <levitte@stacken.kth.se>]
7501 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
7502 from `int' to `unsigned int' because it's a length and initialized by
7503 EVP_DigestFinal() which expects an `unsigned int *'.
7504 [Richard Levitte <levitte@stacken.kth.se>]
7506 *) Don't hard-code path to Perl interpreter on shebang line of Configure
7507 script. Instead use the usual Shell->Perl transition trick.
7508 [Ralf S. Engelschall]
7510 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
7511 (in addition to RSA certificates) to match the behaviour of `openssl dsa
7512 -noout -modulus' as it's already the case for `openssl rsa -noout
7513 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
7514 currently the public key is printed (a decision which was already done by
7515 `openssl dsa -modulus' in the past) which serves a similar purpose.
7516 Additionally the NO_RSA no longer completely removes the whole -modulus
7517 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
7519 [Ralf S. Engelschall]
7521 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
7522 BIO. See the source (crypto/evp/bio_ok.c) for more info.
7523 [Arne Ansper <arne@ats.cyber.ee>]
7525 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
7526 to be added. Now both 'req' and 'ca' can use new objects defined in the
7530 *) Add cool BIO that does syslog (or event log on NT).
7531 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
7533 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
7534 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
7535 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
7536 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
7539 *) Add preliminary config info for new extension code.
7542 *) Make RSA_NO_PADDING really use no padding.
7543 [Ulf Moeller <ulf@fitug.de>]
7545 *) Generate errors when private/public key check is done.
7548 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
7549 for some CRL extensions and new objects added.
7552 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
7553 key usage extension and fuller support for authority key id.
7556 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
7557 padding method for RSA, which is recommended for new applications in PKCS
7558 #1 v2.0 (RFC 2437, October 1998).
7559 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
7560 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
7561 against Bleichbacher's attack on RSA.
7562 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
7565 *) Updates to the new SSL compression code
7566 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
7568 *) Fix so that the version number in the master secret, when passed
7569 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
7570 (because the server will not accept higher), that the version number
7571 is 0x03,0x01, not 0x03,0x00
7572 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
7574 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
7575 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
7576 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
7579 *) Support for RAW extensions where an arbitrary extension can be
7580 created by including its DER encoding. See apps/openssl.cnf for
7584 *) Make sure latest Perl versions don't interpret some generated C array
7585 code as Perl array code in the crypto/err/err_genc.pl script.
7586 [Lars Weber <3weber@informatik.uni-hamburg.de>]
7588 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
7589 not many people have the assembler. Various Win32 compilation fixes and
7590 update to the INSTALL.W32 file with (hopefully) more accurate Win32
7594 *) Modify configure script 'Configure' to automatically create crypto/date.h
7595 file under Win32 and also build pem.h from pem.org. New script
7596 util/mkfiles.pl to create the MINFO file on environments that can't do a
7597 'make files': perl util/mkfiles.pl >MINFO should work.
7600 *) Major rework of DES function declarations, in the pursuit of correctness
7601 and purity. As a result, many evil casts evaporated, and some weirdness,
7602 too. You may find this causes warnings in your code. Zapping your evil
7603 casts will probably fix them. Mostly.
7606 *) Fix for a typo in asn1.h. Bug fix to object creation script
7607 obj_dat.pl. It considered a zero in an object definition to mean
7608 "end of object": none of the objects in objects.h have any zeros
7609 so it wasn't spotted.
7610 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
7612 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
7613 Masking (CBCM). In the absence of test vectors, the best I have been able
7614 to do is check that the decrypt undoes the encrypt, so far. Send me test
7615 vectors if you have them.
7618 *) Correct calculation of key length for export ciphers (too much space was
7619 allocated for null ciphers). This has not been tested!
7622 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
7623 message is now correct (it understands "crypto" and "ssl" on its
7624 command line). There is also now an "update" option. This will update
7625 the util/ssleay.num and util/libeay.num files with any new functions.
7627 perl util/mkdef.pl crypto ssl update
7628 it will update them.
7631 *) Overhauled the Perl interface (perl/*):
7632 - ported BN stuff to OpenSSL's different BN library
7633 - made the perl/ source tree CVS-aware
7634 - renamed the package from SSLeay to OpenSSL (the files still contain
7635 their history because I've copied them in the repository)
7636 - removed obsolete files (the test scripts will be replaced
7637 by better Test::Harness variants in the future)
7638 [Ralf S. Engelschall]
7640 *) First cut for a very conservative source tree cleanup:
7641 1. merge various obsolete readme texts into doc/ssleay.txt
7642 where we collect the old documents and readme texts.
7643 2. remove the first part of files where I'm already sure that we no
7644 longer need them because of three reasons: either they are just temporary
7645 files which were left by Eric or they are preserved original files where
7646 I've verified that the diff is also available in the CVS via "cvs diff
7647 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
7648 the crypto/md/ stuff).
7649 [Ralf S. Engelschall]
7651 *) More extension code. Incomplete support for subject and issuer alt
7652 name, issuer and authority key id. Change the i2v function parameters
7653 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
7654 what that's for :-) Fix to ASN1 macro which messed up
7655 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
7658 *) Preliminary support for ENUMERATED type. This is largely copied from the
7662 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
7663 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
7665 *) Make sure `make rehash' target really finds the `openssl' program.
7666 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
7668 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
7669 like to hear about it if this slows down other processors.
7672 *) Add CygWin32 platform information to Configure script.
7673 [Alan Batie <batie@aahz.jf.intel.com>]
7675 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
7676 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
7678 *) New program nseq to manipulate netscape certificate sequences
7681 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
7685 *) Fixes to BN code. Previously the default was to define BN_RECURSION
7686 but the BN code had some problems that would cause failures when
7687 doing certificate verification and some other functions.
7688 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
7690 *) Add ASN1 and PEM code to support netscape certificate sequences.
7693 *) Add ASN1 and PEM code to support netscape certificate sequences.
7696 *) Add several PKIX and private extended key usage OIDs.
7699 *) Modify the 'ca' program to handle the new extension code. Modify
7700 openssl.cnf for new extension format, add comments.
7703 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
7704 and add a sample to openssl.cnf so req -x509 now adds appropriate
7708 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
7709 error code, add initial support to X509_print() and x509 application.
7712 *) Takes a deep breath and start addding X509 V3 extension support code. Add
7713 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
7714 stuff is currently isolated and isn't even compiled yet.
7717 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
7718 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
7719 Removed the versions check from X509 routines when loading extensions:
7720 this allows certain broken certificates that don't set the version
7721 properly to be processed.
7724 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
7725 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
7726 can still be regenerated with "make depend".
7729 *) Spelling mistake in C version of CAST-128.
7730 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
7732 *) Changes to the error generation code. The perl script err-code.pl
7733 now reads in the old error codes and retains the old numbers, only
7734 adding new ones if necessary. It also only changes the .err files if new
7735 codes are added. The makefiles have been modified to only insert errors
7736 when needed (to avoid needlessly modifying header files). This is done
7737 by only inserting errors if the .err file is newer than the auto generated
7738 C file. To rebuild all the error codes from scratch (the old behaviour)
7739 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
7740 or delete all the .err files.
7743 *) CAST-128 was incorrectly implemented for short keys. The C version has
7744 been fixed, but is untested. The assembler versions are also fixed, but
7745 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
7746 to regenerate it if needed.
7747 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
7748 Hagino <itojun@kame.net>]
7750 *) File was opened incorrectly in randfile.c.
7751 [Ulf Möller <ulf@fitug.de>]
7753 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
7754 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
7755 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
7756 al: it's just almost always a UTCTime. Note this patch adds new error
7757 codes so do a "make errors" if there are problems.
7760 *) Correct Linux 1 recognition in config.
7761 [Ulf Möller <ulf@fitug.de>]
7763 *) Remove pointless MD5 hash when using DSA keys in ca.
7764 [Anonymous <nobody@replay.com>]
7766 *) Generate an error if given an empty string as a cert directory. Also
7767 generate an error if handed NULL (previously returned 0 to indicate an
7768 error, but didn't set one).
7769 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
7771 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
7774 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
7775 parameters. This was causing a warning which killed off the Win32 compile.
7778 *) Remove C++ style comments from crypto/bn/bn_local.h.
7779 [Neil Costigan <neil.costigan@celocom.com>]
7781 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
7782 based on a text string, looking up short and long names and finally
7783 "dot" format. The "dot" format stuff didn't work. Added new function
7784 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
7785 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
7786 OID is not part of the table.
7789 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
7790 X509_LOOKUP_by_alias().
7793 *) Sort openssl functions by name.
7796 *) Get the gendsa program working (hopefully) and add it to app list. Remove
7797 encryption from sample DSA keys (in case anyone is interested the password
7801 *) Make _all_ *_free functions accept a NULL pointer.
7802 [Frans Heymans <fheymans@isaserver.be>]
7804 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
7806 [Anonymous <nobody@replay.com>]
7808 *) s_server should send the CAfile as acceptable CAs, not its own cert.
7809 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
7811 *) Don't blow it for numeric -newkey arguments to apps/req.
7812 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
7814 *) Temp key "for export" tests were wrong in s3_srvr.c.
7815 [Anonymous <nobody@replay.com>]
7817 *) Add prototype for temp key callback functions
7818 SSL_CTX_set_tmp_{rsa,dh}_callback().
7821 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
7822 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
7825 *) X509_name_add_entry() freed the wrong thing after an error.
7826 [Arne Ansper <arne@ats.cyber.ee>]
7828 *) rsa_eay.c would attempt to free a NULL context.
7829 [Arne Ansper <arne@ats.cyber.ee>]
7831 *) BIO_s_socket() had a broken should_retry() on Windoze.
7832 [Arne Ansper <arne@ats.cyber.ee>]
7834 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
7835 [Arne Ansper <arne@ats.cyber.ee>]
7837 *) Make sure the already existing X509_STORE->depth variable is initialized
7838 in X509_STORE_new(), but document the fact that this variable is still
7839 unused in the certificate verification process.
7840 [Ralf S. Engelschall]
7842 *) Fix the various library and apps files to free up pkeys obtained from
7843 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
7846 *) Fix reference counting in X509_PUBKEY_get(). This makes
7847 demos/maurice/example2.c work, amongst others, probably.
7848 [Steve Henson and Ben Laurie]
7850 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
7851 `openssl' and second, the shortcut symlinks for the `openssl <command>'
7852 are no longer created. This way we have a single and consistent command
7853 line interface `openssl <command>', similar to `cvs <command>'.
7854 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
7856 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
7857 BIT STRING wrapper always have zero unused bits.
7860 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
7863 *) Make the top-level INSTALL documentation easier to understand.
7866 *) Makefiles updated to exit if an error occurs in a sub-directory
7867 make (including if user presses ^C) [Paul Sutton]
7869 *) Make Montgomery context stuff explicit in RSA data structure.
7872 *) Fix build order of pem and err to allow for generated pem.h.
7875 *) Fix renumbering bug in X509_NAME_delete_entry().
7878 *) Enhanced the err-ins.pl script so it makes the error library number
7879 global and can add a library name. This is needed for external ASN1 and
7880 other error libraries.
7883 *) Fixed sk_insert which never worked properly.
7886 *) Fix ASN1 macros so they can handle indefinite length construted
7887 EXPLICIT tags. Some non standard certificates use these: they can now
7891 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
7892 into a single doc/ssleay.txt bundle. This way the information is still
7893 preserved but no longer messes up this directory. Now it's new room for
7894 the new set of documenation files.
7895 [Ralf S. Engelschall]
7897 *) SETs were incorrectly DER encoded. This was a major pain, because they
7898 shared code with SEQUENCEs, which aren't coded the same. This means that
7899 almost everything to do with SETs or SEQUENCEs has either changed name or
7900 number of arguments.
7901 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
7903 *) Fix test data to work with the above.
7906 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
7907 was already fixed by Eric for 0.9.1 it seems.
7908 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
7910 *) Autodetect FreeBSD3.
7913 *) Fix various bugs in Configure. This affects the following platforms:
7917 unixware-2.0-pentium
7921 *) Eliminate generated files from CVS. Reorder tests to regenerate files
7922 before they are needed.
7925 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
7929 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
7931 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
7932 changed SSLeay to OpenSSL in version strings.
7933 [Ralf S. Engelschall]
7935 *) Some fixups to the top-level documents.
7938 *) Fixed the nasty bug where rsaref.h was not found under compile-time
7939 because the symlink to include/ was missing.
7940 [Ralf S. Engelschall]
7942 *) Incorporated the popular no-RSA/DSA-only patches
7943 which allow to compile a RSA-free SSLeay.
7944 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
7946 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
7947 when "ssleay" is still not found.
7948 [Ralf S. Engelschall]
7950 *) Added more platforms to Configure: Cray T3E, HPUX 11,
7951 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
7953 *) Updated the README file.
7954 [Ralf S. Engelschall]
7956 *) Added various .cvsignore files in the CVS repository subdirs
7957 to make a "cvs update" really silent.
7958 [Ralf S. Engelschall]
7960 *) Recompiled the error-definition header files and added
7961 missing symbols to the Win32 linker tables.
7962 [Ralf S. Engelschall]
7964 *) Cleaned up the top-level documents;
7965 o new files: CHANGES and LICENSE
7966 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
7967 o merged COPYRIGHT into LICENSE
7968 o removed obsolete TODO file
7969 o renamed MICROSOFT to INSTALL.W32
7970 [Ralf S. Engelschall]
7972 *) Removed dummy files from the 0.9.1b source tree:
7973 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
7974 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

7977 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
7978 [Ralf S. Engelschall]
7980 *) Added various platform portability fixes.
7983 *) The Genesis of the OpenSSL rpject:
7984 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
7985 Young and Tim J. Hudson created while they were working for C2Net until
7987 [The OpenSSL Project]
7990 Changes between 0.9.0b and 0.9.1b [not released]
7992 *) Updated a few CA certificates under certs/
7995 *) Changed some BIGNUM api stuff.
7998 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
7999 DGUX x86, Linux Alpha, etc.
8002 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
8003 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
8007 *) Add -strparse option to asn1pars program which parses nested
8009 [Dr Stephen Henson <shenson@bigfoot.com>]
8011 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
8014 *) DSA fix for "ca" program.
8017 *) Added "-genkey" option to "dsaparam" program.
8020 *) Added RIPE MD160 (rmd160) message digest.
8023 *) Added -a (all) option to "ssleay version" command.
8026 *) Added PLATFORM define which is the id given to Configure.
8029 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
8032 *) Extended the ASN.1 parser routines.
8035 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
8038 *) Added a BN_CTX to the BN library.
8041 *) Fixed the weak key values in DES library
8044 *) Changed API in EVP library for cipher aliases.
8047 *) Added support for RC2/64bit cipher.
8050 *) Converted the lhash library to the crypto/mem.c functions.
8053 *) Added more recognized ASN.1 object ids.
8056 *) Added more RSA padding checks for SSL/TLS.
8059 *) Added BIO proxy/filter functionality.
8062 *) Added extra_certs to SSL_CTX which can be used
8063 send extra CA certificates to the client in the CA cert chain sending
8064 process. It can be configured with SSL_CTX_add_extra_chain_cert().
8067 *) Now Fortezza is denied in the authentication phase because
8068 this is key exchange mechanism is not supported by SSLeay at all.
8071 *) Additional PKCS1 checks.
8074 *) Support the string "TLSv1" for all TLS v1 ciphers.
8077 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
8078 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
8081 *) Fixed a few memory leaks.
8084 *) Fixed various code and comment typos.
8087 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
8088 bytes sent in the client random.
