5 Changes between 0.9.8b and 0.9.9 [xx XXX xxxx]
7 *) Allow digests to supply their own micalg string for S/MIME type using
8 the ctrl EVP_MD_CTRL_MICALG.
11 *) During PKCS7 signing pass the PKCS7 SignerInfo structure to the
12 EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN
13 ctrl. It can then customise the structure before and/or after signing
17 *) New function OBJ_add_sigid() to allow application defined signature OIDs
18 to be added to OpenSSLs internal tables. New function OBJ_sigid_free()
19 to free up any added signature OIDs.
22 *) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(),
23 EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal
24 digest and cipher tables. New options added to openssl utility:
25 list-message-digest-algorithms and list-cipher-algorithms.
28 *) In addition to the numerical (unsigned long) thread ID, provide
29 for a pointer (void *) thread ID. This helps accomodate systems
30 that do not provide an unsigned long thread ID. OpenSSL assumes
31 it is in the same thread iff both the numerical and the pointer
32 thread ID agree; so applications are just required to define one
33 of them appropriately (e.g., by using a pointer to a per-thread
34 memory object malloc()ed by the application for the pointer-type
35 thread ID). Exactly analoguous to the existing functions
37 void CRYPTO_set_id_callback(unsigned long (*func)(void));
38 unsigned long (*CRYPTO_get_id_callback(void))(void);
39 unsigned long CRYPTO_thread_id(void);
41 we now have additional functions
43 void CRYPTO_set_idptr_callback(void *(*func)(void));
44 void *(*CRYPTO_get_idptr_callback(void))(void);
45 void *CRYPTO_thread_idptr(void);
47 also in <openssl/crypto.h>. The default value for
48 CRYPTO_thread_idptr() if the application has not provided its own
52 *) Change the array representation of binary polynomials: the list
53 of degrees of non-zero coefficients is now terminated with -1.
54 Previously it was terminated with 0, which was also part of the
55 value; thus, the array representation was not applicable to
56 polynomials where t^0 has coefficient zero. This change makes
57 the array representation useful in a more general context.
60 *) Various modifications and fixes to SSL/TLS cipher string
61 handling. For ECC, the code now distinguishes between fixed ECDH
62 with RSA certificates on the one hand and with ECDSA certificates
63 on the other hand, since these are separate ciphersuites. The
64 unused code for Fortezza ciphersuites has been removed.
66 For consistency with EDH, ephemeral ECDH is now called "EECDH"
67 (not "ECDHE"). For consistency with the code for DH
68 certificates, use of ECDH certificates is now considered ECDH
69 authentication, not RSA or ECDSA authentication (the latter is
70 merely the CA's signing algorithm and not actively used in the
73 The temporary ciphersuite alias "ECCdraft" is no longer
74 available, and ECC ciphersuites are no longer excluded from "ALL"
75 and "DEFAULT". The following aliases now exist for RFC 4492
76 ciphersuites, most of these by analogy with the DH case:
78 kECDHr - ECDH cert, signed with RSA
79 kECDHe - ECDH cert, signed with ECDSA
80 kECDH - ECDH cert (signed with either RSA or ECDSA)
81 kEECDH - ephemeral ECDH
82 ECDH - ECDH cert or ephemeral ECDH
88 AECDH - anonymous ECDH
89 EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH")
93 *) Add additional S/MIME capabilities for AES and GOST ciphers if supported.
94 Use correct micalg parameters depending on digest(s) in signed message.
97 *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process
98 an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code.
101 *) Initial engine support for EVP_PKEY_METHOD. New functions to permit
102 an engine to register a method. Add ENGINE lookups for methods and
103 functional reference processing.
106 *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of
107 EVP_{Sign,Verify}* which allow an application to customise the signature
111 *) New -resign option to smime utility. This adds one or more signers
112 to an existing PKCS#7 signedData structure. Also -md option to use an
113 alternative message digest algorithm for signing.
116 *) Tidy up PKCS#7 routines and add new functions to make it easier to
117 create PKCS7 structures containing multiple signers. Update smime
118 application to support multiple signers.
121 *) New -macalg option to pkcs12 utility to allow setting of an alternative
125 *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC.
126 Reorganize PBE internals to lookup from a static table using NIDs,
127 add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl:
128 EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative
129 PRF which will be automatically used with PBES2.
132 *) Replace the algorithm specific calls to generate keys in "req" with the
136 *) Update PKCS#7 enveloped data routines to use new API. This is now
137 supported by any public key method supporting the encrypt operation. A
138 ctrl is added to allow the public key algorithm to examine or modify
139 the PKCS#7 RecipientInfo structure if it needs to: for RSA this is
143 *) Add a ctrl to asn1 method to allow a public key algorithm to express
144 a default digest type to use. In most cases this will be SHA1 but some
145 algorithms (such as GOST) need to specify an alternative digest. The
146 return value indicates how strong the prefernce is 1 means optional and
147 2 is mandatory (that is it is the only supported type). Modify
148 ASN1_item_sign() to accept a NULL digest argument to indicate it should
149 use the default md. Update openssl utilities to use the default digest
150 type for signing if it is not explicitly indicated.
153 *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New
154 EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant
155 signing method from the key type. This effectively removes the link
156 between digests and public key types.
159 *) Add an OID cross reference table and utility functions. Its purpose is to
160 translate between signature OIDs such as SHA1WithrsaEncryption and SHA1,
161 rsaEncryption. This will allow some of the algorithm specific hackery
162 needed to use the correct OID to be removed.
165 *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO
166 structures for PKCS7_sign(). They are now set up by the relevant public
170 *) Add provisional EC pkey method with support for ECDSA and ECDH.
173 *) Add support for key derivation (agreement) in the API, DH method and
177 *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support
178 public and private key formats. As a side effect these add additional
179 command line functionality not previously available: DSA signatures can be
180 generated and verified using pkeyutl and DH key support and generation in
185 [Oliver Tappe <zooey@hirschkaefer.de>]
187 *) New make target "install_html_docs" installs HTML renditions of the
189 [Oliver Tappe <zooey@hirschkaefer.de>]
191 *) New utility "genpkey" this is analagous to "genrsa" etc except it can
192 generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to
193 support key and parameter generation and add initial key generation
194 functionality for RSA.
197 *) Add functions for main EVP_PKEY_method operations. The undocumented
198 functions EVP_PKEY_{encrypt,decrypt} have been renamed to
199 EVP_PKEY_{encrypt,decrypt}_old.
202 *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public
203 key API, doesn't do much yet.
206 *) New function EVP_PKEY_asn1_get0_info() to retrieve information about
207 public key algorithms. New option to openssl utility:
208 "list-public-key-algorithms" to print out info.
211 *) Implement the Supported Elliptic Curves Extension for
212 ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
215 *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or
216 EVP_CIPHER structures to avoid later problems in EVP_cleanup().
219 *) New utilities pkey and pkeyparam. These are similar to algorithm specific
220 utilities such as rsa, dsa, dsaparam etc except they process any key
224 *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New
225 functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
226 EVP_PKEY_print_param() to print public key data from an EVP_PKEY
230 *) Initial support for pluggable public key ASN1.
231 De-spaghettify the public key ASN1 handling. Move public and private
232 key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate
233 algorithm specific handling to a single module within the relevant
234 algorithm directory. Add functions to allow (near) opaque processing
235 of public and private key structures.
238 *) Implement the Supported Point Formats Extension for
239 ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
242 *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members
243 for the psk identity [hint] and the psk callback functions to the
244 SSL_SESSION, SSL and SSL_CTX structure.
247 PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA,
251 SSL_CTX_use_psk_identity_hint
252 SSL_get_psk_identity_hint
254 SSL_use_psk_identity_hint
256 [Mika Kousa and Pasi Eronen of Nokia Corporation]
258 *) Add RFC 3161 compliant time stamp request creation, response generation
259 and response verification functionality.
260 [Zoltán Glózik <zglozik@opentsa.org>, The OpenTSA Project]
262 *) Add initial support for TLS extensions, specifically for the server_name
263 extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now
264 have new members for a host name. The SSL data structure has an
265 additional member SSL_CTX *initial_ctx so that new sessions can be
266 stored in that context to allow for session resumption, even after the
267 SSL has been switched to a new SSL_CTX in reaction to a client's
268 server_name extension.
270 New functions (subject to change):
273 SSL_get_servername_type()
276 New CTRL codes and macros (subject to change):
278 SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
279 - SSL_CTX_set_tlsext_servername_callback()
280 SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG
281 - SSL_CTX_set_tlsext_servername_arg()
282 SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_hostname()
284 openssl s_client has a new '-servername ...' option.
286 openssl s_server has new options '-servername_host ...', '-cert2 ...',
287 '-key2 ...', '-servername_fatal' (subject to change). This allows
288 testing the HostName extension for a specific single host name ('-cert'
289 and '-key' remain fallbacks for handshakes without HostName
290 negotiation). If the unrecogninzed_name alert has to be sent, this by
291 default is a warning; it becomes fatal with the '-servername_fatal'
294 [Peter Sylvester, Remy Allais, Christophe Renou]
296 *) Whirlpool hash implementation is added.
299 *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to
300 bn(64,32). Because of instruction set limitations it doesn't have
301 any negative impact on performance. This was done mostly in order
302 to make it possible to share assembler modules, such as bn_mul_mont
303 implementations, between 32- and 64-bit builds without hassle.
306 *) Move code previously exiled into file crypto/ec/ec2_smpt.c
307 to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP
311 *) New candidate for BIGNUM assembler implementation, bn_mul_mont,
312 dedicated Montgomery multiplication procedure, is introduced.
313 BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher
314 "64-bit" performance on certain 32-bit targets.
317 *) New option SSL_OP_NO_COMP to disable use of compression selectively
318 in SSL structures. New SSL ctrl to set maximum send fragment size.
319 Save memory by seeting the I/O buffer sizes dynamically instead of
320 using the maximum available value.
323 *) New option -V for 'openssl ciphers'. This prints the ciphersuite code
324 in addition to the text details.
327 *) Very, very preliminary EXPERIMENTAL support for printing of general
328 ASN1 structures. This currently produces rather ugly output and doesn't
329 handle several customised structures at all.
332 *) Integrated support for PVK file format and some related formats such
333 as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
334 these in the 'rsa' and 'dsa' utilities.
337 *) Support for PKCS#1 RSAPublicKey format on rsa utility command line.
340 *) Remove the ancient ASN1_METHOD code. This was only ever used in one
341 place for the (very old) "NETSCAPE" format certificates which are now
342 handled using new ASN1 code equivalents.
345 *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD
346 pointer and make the SSL_METHOD parameter in SSL_CTX_new,
347 SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'.
350 *) Modify CRL distribution points extension code to print out previously
351 unsupported fields. Enhance extension setting code to allow setting of
355 *) Add print and set support for Issuing Distribution Point CRL extension.
358 *) Change 'Configure' script to enable Camellia by default.
361 Changes between 0.9.8b and 0.9.8c [xx XXX xxxx]
363 *) Change the Unix randomness entropy gathering to use poll() when
364 possible instead of select(), since the latter has some
365 undesirable limitations.
366 [Darryl Miles via Richard Levitte and Bodo Moeller]
368 *) Disable "ECCdraft" ciphersuites more thoroughly. Now special
369 treatment in ssl/ssl_ciph.s makes sure that these ciphersuites
370 cannot be implicitly activated as part of, e.g., the "AES" alias.
371 However, please upgrade to OpenSSL 0.9.9[-dev] for
372 non-experimental use of the ECC ciphersuites to get TLS extension
373 support, which is required for curve and point format negotiation
374 to avoid potential handshake problems.
377 *) Disable rogue ciphersuites:
379 - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
380 - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
381 - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
383 The latter two were purportedly from
384 draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
387 Also deactive the remaining ciphersuites from
388 draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as
389 unofficial, and the ID has long expired.
392 *) Fix RSA blinding Heisenbug (problems sometimes occured on
393 dual-core machines) and other potential thread-safety issues.
396 *) Add the symmetric cipher Camellia (128-bit, 192-bit, 256-bit key
397 versions), which is now available for royalty-free use
398 (see http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html).
399 Also, add Camellia TLS ciphersuites from RFC 4132.
401 To minimize changes between patchlevels in the OpenSSL 0.9.8
402 series, Camellia remains excluded from compilation unless OpenSSL
403 is configured with 'enable-camellia'.
406 *) Disable the padding bug check when compression is in use. The padding
407 bug check assumes the first packet is of even length, this is not
408 necessarily true if compresssion is enabled and can result in false
409 positives causing handshake failure. The actual bug test is ancient
410 code so it is hoped that implementations will either have fixed it by
411 now or any which still have the bug do not support compression.
414 Changes between 0.9.8a and 0.9.8b [04 May 2006]
416 *) When applying a cipher rule check to see if string match is an explicit
417 cipher suite and only match that one cipher suite if it is.
420 *) Link in manifests for VC++ if needed.
421 [Austin Ziegler <halostatue@gmail.com>]
423 *) Update support for ECC-based TLS ciphersuites according to
424 draft-ietf-tls-ecc-12.txt with proposed changes (but without
425 TLS extensions, which are supported starting with the 0.9.9
426 branch, not in the OpenSSL 0.9.8 branch).
429 *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support
430 opaque EVP_CIPHER_CTX handling.
433 *) Fixes and enhancements to zlib compression code. We now only use
434 "zlib1.dll" and use the default __cdecl calling convention on Win32
435 to conform with the standards mentioned here:
436 http://www.zlib.net/DLL_FAQ.txt
437 Static zlib linking now works on Windows and the new --with-zlib-include
438 --with-zlib-lib options to Configure can be used to supply the location
439 of the headers and library. Gracefully handle case where zlib library
443 *) Several fixes and enhancements to the OID generation code. The old code
444 sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't
445 handle numbers larger than ULONG_MAX, truncated printing and had a
446 non standard OBJ_obj2txt() behaviour.
449 *) Add support for building of engines under engine/ as shared libraries
450 under VC++ build system.
453 *) Corrected the numerous bugs in the Win32 path splitter in DSO.
454 Hopefully, we will not see any false combination of paths any more.
457 Changes between 0.9.8 and 0.9.8a [11 Oct 2005]
459 *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
460 (part of SSL_OP_ALL). This option used to disable the
461 countermeasure against man-in-the-middle protocol-version
462 rollback in the SSL 2.0 server implementation, which is a bad
463 idea. (CVE-2005-2969)
465 [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
466 for Information Security, National Institute of Advanced Industrial
467 Science and Technology [AIST], Japan)]
469 *) Add two function to clear and return the verify parameter flags.
472 *) Keep cipherlists sorted in the source instead of sorting them at
473 runtime, thus removing the need for a lock.
476 *) Avoid some small subgroup attacks in Diffie-Hellman.
477 [Nick Mathewson and Ben Laurie]
479 *) Add functions for well-known primes.
482 *) Extended Windows CE support.
483 [Satoshi Nakamura and Andy Polyakov]
485 *) Initialize SSL_METHOD structures at compile time instead of during
486 runtime, thus removing the need for a lock.
489 *) Make PKCS7_decrypt() work even if no certificate is supplied by
490 attempting to decrypt each encrypted key in turn. Add support to
494 Changes between 0.9.7h and 0.9.8 [05 Jul 2005]
496 [NB: OpenSSL 0.9.7i and later 0.9.7 patch levels were released after
499 *) Add libcrypto.pc and libssl.pc for those who feel they need them.
502 *) Change CA.sh and CA.pl so they don't bundle the CSR and the private
503 key into the same file any more.
506 *) Add initial support for Win64, both IA64 and AMD64/x64 flavors.
509 *) Add -utf8 command line and config file option to 'ca'.
510 [Stefan <stf@udoma.org]
512 *) Removed the macro des_crypt(), as it seems to conflict with some
513 libraries. Use DES_crypt().
516 *) Correct naming of the 'chil' and '4758cca' ENGINEs. This
517 involves renaming the source and generated shared-libs for
518 both. The engines will accept the corrected or legacy ids
519 ('ncipher' and '4758_cca' respectively) when binding. NB,
520 this only applies when building 'shared'.
521 [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe]
523 *) Add attribute functions to EVP_PKEY structure. Modify
524 PKCS12_create() to recognize a CSP name attribute and
525 use it. Make -CSP option work again in pkcs12 utility.
528 *) Add new functionality to the bn blinding code:
529 - automatic re-creation of the BN_BLINDING parameters after
530 a fixed number of uses (currently 32)
531 - add new function for parameter creation
532 - introduce flags to control the update behaviour of the
533 BN_BLINDING parameters
534 - hide BN_BLINDING structure
535 Add a second BN_BLINDING slot to the RSA structure to improve
536 performance when a single RSA object is shared among several
540 *) Add support for DTLS.
541 [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]
543 *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
544 to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
547 *) Remove buggy and incompletet DH cert support from
548 ssl/ssl_rsa.c and ssl/s3_both.c
551 *) Use SHA-1 instead of MD5 as the default digest algorithm for
552 the apps/openssl applications.
555 *) Compile clean with "-Wall -Wmissing-prototypes
556 -Wstrict-prototypes -Wmissing-declarations -Werror". Currently
557 DEBUG_SAFESTACK must also be set.
560 *) Change ./Configure so that certain algorithms can be disabled by default.
561 The new counterpiece to "no-xxx" is "enable-xxx".
563 The patented RC5 and MDC2 algorithms will now be disabled unless
564 "enable-rc5" and "enable-mdc2", respectively, are specified.
566 (IDEA remains enabled despite being patented. This is because IDEA
567 is frequently required for interoperability, and there is no license
568 fee for non-commercial use. As before, "no-idea" can be used to
569 avoid this algorithm.)
573 *) Add processing of proxy certificates (see RFC 3820). This work was
574 sponsored by KTH (The Royal Institute of Technology in Stockholm) and
575 EGEE (Enabling Grids for E-science in Europe).
578 *) RC4 performance overhaul on modern architectures/implementations, such
579 as Intel P4, IA-64 and AMD64.
582 *) New utility extract-section.pl. This can be used specify an alternative
583 section number in a pod file instead of having to treat each file as
584 a separate case in Makefile. This can be done by adding two lines to the
587 =for comment openssl_section:XXX
589 The blank line is mandatory.
593 *) New arguments -certform, -keyform and -pass for s_client and s_server
594 to allow alternative format key and certificate files and passphrase
598 *) New structure X509_VERIFY_PARAM which combines current verify parameters,
599 update associated structures and add various utility functions.
601 Add new policy related verify parameters, include policy checking in
602 standard verify code. Enhance 'smime' application with extra parameters
603 to support policy checking and print out.
606 *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3
607 Nehemiah processors. These extensions support AES encryption in hardware
608 as well as RNG (though RNG support is currently disabled).
609 [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov]
611 *) Deprecate BN_[get|set]_params() functions (they were ignored internally).
614 *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented.
615 [Andy Polyakov and a number of other people]
617 *) Improved PowerPC platform support. Most notably BIGNUM assembler
618 implementation contributed by IBM.
619 [Suresh Chari, Peter Waltenberg, Andy Polyakov]
621 *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public
622 exponent rather than 'unsigned long'. There is a corresponding change to
623 the new 'rsa_keygen' element of the RSA_METHOD structure.
624 [Jelte Jansen, Geoff Thorpe]
626 *) Functionality for creating the initial serial number file is now
627 moved from CA.pl to the 'ca' utility with a new option -create_serial.
629 (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial
630 number file to 1, which is bound to cause problems. To avoid
631 the problems while respecting compatibility between different 0.9.7
632 patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in
633 CA.pl for serial number initialization. With the new release 0.9.8,
634 we can fix the problem directly in the 'ca' utility.)
637 *) Reduced header interdepencies by declaring more opaque objects in
638 ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
639 give fewer recursive includes, which could break lazy source code - so
640 this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
641 developers should define this symbol when building and using openssl to
642 ensure they track the recommended behaviour, interfaces, [etc], but
643 backwards-compatible behaviour prevails when this isn't defined.
646 *) New function X509_POLICY_NODE_print() which prints out policy nodes.
649 *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
650 This will generate a random key of the appropriate length based on the
651 cipher context. The EVP_CIPHER can provide its own random key generation
652 routine to support keys of a specific form. This is used in the des and
653 3des routines to generate a key of the correct parity. Update S/MIME
654 code to use new functions and hence generate correct parity DES keys.
655 Add EVP_CHECK_DES_KEY #define to return an error if the key is not
656 valid (weak or incorrect parity).
659 *) Add a local set of CRLs that can be used by X509_verify_cert() as well
660 as looking them up. This is useful when the verified structure may contain
661 CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
662 present unless the new PKCS7_NO_CRL flag is asserted.
665 *) Extend ASN1 oid configuration module. It now additionally accepts the
668 shortName = some long name, 1.2.3.4
671 *) Reimplemented the BN_CTX implementation. There is now no more static
672 limitation on the number of variables it can handle nor the depth of the
673 "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
674 information can now expand as required, and rather than having a single
675 static array of bignums, BN_CTX now uses a linked-list of such arrays
676 allowing it to expand on demand whilst maintaining the usefulness of
680 *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
681 to allow all RSA operations to function using a single BN_CTX.
684 *) Preliminary support for certificate policy evaluation and checking. This
685 is initially intended to pass the tests outlined in "Conformance Testing
686 of Relying Party Client Certificate Path Processing Logic" v1.07.
689 *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and
690 remained unused and not that useful. A variety of other little bignum
691 tweaks and fixes have also been made continuing on from the audit (see
695 *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with
696 associated ASN1, EVP and SSL functions and old ASN1 macros.
699 *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
700 and this should never fail. So the return value from the use of
701 BN_set_word() (which can fail due to needless expansion) is now deprecated;
702 if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro.
705 *) BN_CTX_get() should return zero-valued bignums, providing the same
706 initialised value as BN_new().
707 [Geoff Thorpe, suggested by Ulf Möller]
709 *) Support for inhibitAnyPolicy certificate extension.
712 *) An audit of the BIGNUM code is underway, for which debugging code is
713 enabled when BN_DEBUG is defined. This makes stricter enforcements on what
714 is considered valid when processing BIGNUMs, and causes execution to
715 assert() when a problem is discovered. If BN_DEBUG_RAND is defined,
716 further steps are taken to deliberately pollute unused data in BIGNUM
717 structures to try and expose faulty code further on. For now, openssl will
718 (in its default mode of operation) continue to tolerate the inconsistent
719 forms that it has tolerated in the past, but authors and packagers should
720 consider trying openssl and their own applications when compiled with
721 these debugging symbols defined. It will help highlight potential bugs in
722 their own code, and will improve the test coverage for OpenSSL itself. At
723 some point, these tighter rules will become openssl's default to improve
724 maintainability, though the assert()s and other overheads will remain only
725 in debugging configurations. See bn.h for more details.
726 [Geoff Thorpe, Nils Larsch, Ulf Möller]
728 *) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure
729 that can only be obtained through BN_CTX_new() (which implicitly
730 initialises it). The presence of this function only made it possible
731 to overwrite an existing structure (and cause memory leaks).
734 *) Because of the callback-based approach for implementing LHASH as a
735 template type, lh_insert() adds opaque objects to hash-tables and
736 lh_doall() or lh_doall_arg() are typically used with a destructor callback
737 to clean up those corresponding objects before destroying the hash table
738 (and losing the object pointers). So some over-zealous constifications in
739 LHASH have been relaxed so that lh_insert() does not take (nor store) the
740 objects as "const" and the lh_doall[_arg] callback wrappers are not
741 prototyped to have "const" restrictions on the object pointers they are
742 given (and so aren't required to cast them away any more).
745 *) The tmdiff.h API was so ugly and minimal that our own timing utility
746 (speed) prefers to use its own implementation. The two implementations
747 haven't been consolidated as yet (volunteers?) but the tmdiff API has had
748 its object type properly exposed (MS_TM) instead of casting to/from "char
749 *". This may still change yet if someone realises MS_TM and "ms_time_***"
750 aren't necessarily the greatest nomenclatures - but this is what was used
751 internally to the implementation so I've used that for now.
754 *) Ensure that deprecated functions do not get compiled when
755 OPENSSL_NO_DEPRECATED is defined. Some "openssl" subcommands and a few of
756 the self-tests were still using deprecated key-generation functions so
757 these have been updated also.
760 *) Reorganise PKCS#7 code to separate the digest location functionality
761 into PKCS7_find_digest(), digest addtion into PKCS7_bio_add_digest().
762 New function PKCS7_set_digest() to set the digest type for PKCS#7
763 digestedData type. Add additional code to correctly generate the
764 digestedData type and add support for this type in PKCS7 initialization
768 *) New function PKCS7_set0_type_other() this initializes a PKCS7
769 structure of type "other".
772 *) Fix prime generation loop in crypto/bn/bn_prime.pl by making
773 sure the loop does correctly stop and breaking ("division by zero")
774 modulus operations are not performed. The (pre-generated) prime
775 table crypto/bn/bn_prime.h was already correct, but it could not be
776 re-generated on some platforms because of the "division by zero"
777 situation in the script.
778 [Ralf S. Engelschall]
780 *) Update support for ECC-based TLS ciphersuites according to
781 draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with
782 SHA-1 now is only used for "small" curves (where the
783 representation of a field element takes up to 24 bytes); for
784 larger curves, the field element resulting from ECDH is directly
785 used as premaster secret.
786 [Douglas Stebila (Sun Microsystems Laboratories)]
788 *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2
789 curve secp160r1 to the tests.
790 [Douglas Stebila (Sun Microsystems Laboratories)]
792 *) Add the possibility to load symbols globally with DSO.
793 [Götz Babin-Ebell <babin-ebell@trustcenter.de> via Richard Levitte]
795 *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better
796 control of the error stack.
799 *) Add support for STORE in ENGINE.
802 *) Add the STORE type. The intention is to provide a common interface
803 to certificate and key stores, be they simple file-based stores, or
804 HSM-type store, or LDAP stores, or...
805 NOTE: The code is currently UNTESTED and isn't really used anywhere.
808 *) Add a generic structure called OPENSSL_ITEM. This can be used to
809 pass a list of arguments to any function as well as provide a way
810 for a function to pass data back to the caller.
813 *) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup()
814 works like BUF_strdup() but can be used to duplicate a portion of
815 a string. The copy gets NUL-terminated. BUF_memdup() duplicates
819 *) Add the function sk_find_ex() which works like sk_find(), but will
820 return an index to an element even if an exact match couldn't be
821 found. The index is guaranteed to point at the element where the
822 searched-for key would be inserted to preserve sorting order.
825 *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but
826 takes an extra flags argument for optional functionality. Currently,
827 the following flags are defined:
829 OBJ_BSEARCH_VALUE_ON_NOMATCH
830 This one gets OBJ_bsearch_ex() to return a pointer to the first
831 element where the comparing function returns a negative or zero
834 OBJ_BSEARCH_FIRST_VALUE_ON_MATCH
835 This one gets OBJ_bsearch_ex() to return a pointer to the first
836 element where the comparing function returns zero. This is useful
837 if there are more than one element where the comparing function
841 *) Make it possible to create self-signed certificates with 'openssl ca'
842 in such a way that the self-signed certificate becomes part of the
843 CA database and uses the same mechanisms for serial number generation
844 as all other certificate signing. The new flag '-selfsign' enables
845 this functionality. Adapt CA.sh and CA.pl.in.
848 *) Add functionality to check the public key of a certificate request
849 against a given private. This is useful to check that a certificate
850 request can be signed by that key (self-signing).
853 *) Make it possible to have multiple active certificates with the same
854 subject in the CA index file. This is done only if the keyword
855 'unique_subject' is set to 'no' in the main CA section (default
856 if 'CA_default') of the configuration file. The value is saved
857 with the database itself in a separate index attribute file,
858 named like the index file with '.attr' appended to the name.
861 *) Generate muti valued AVAs using '+' notation in config files for
865 *) Support for nameConstraints certificate extension.
868 *) Support for policyConstraints certificate extension.
871 *) Support for policyMappings certificate extension.
874 *) Make sure the default DSA_METHOD implementation only uses its
875 dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL,
876 and change its own handlers to be NULL so as to remove unnecessary
877 indirection. This lets alternative implementations fallback to the
878 default implementation more easily.
881 *) Support for directoryName in GeneralName related extensions
885 *) Make it possible to link applications using Makefile.shared.
886 Make that possible even when linking against static libraries!
889 *) Support for single pass processing for S/MIME signing. This now
890 means that S/MIME signing can be done from a pipe, in addition
891 cleartext signing (multipart/signed type) is effectively streaming
892 and the signed data does not need to be all held in memory.
894 This is done with a new flag PKCS7_STREAM. When this flag is set
895 PKCS7_sign() only initializes the PKCS7 structure and the actual signing
896 is done after the data is output (and digests calculated) in
900 *) Add full support for -rpath/-R, both in shared libraries and
901 applications, at least on the platforms where it's known how
905 *) In crypto/ec/ec_mult.c, implement fast point multiplication with
906 precomputation, based on wNAF splitting: EC_GROUP_precompute_mult()
907 will now compute a table of multiples of the generator that
908 makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul()
909 faster (notably in the case of a single point multiplication,
911 [Nils Larsch, Bodo Moeller]
913 *) IPv6 support for certificate extensions. The various extensions
914 which use the IP:a.b.c.d can now take IPv6 addresses using the
915 formats of RFC1884 2.2 . IPv6 addresses are now also displayed
919 *) Added an ENGINE that implements RSA by performing private key
920 exponentiations with the GMP library. The conversions to and from
921 GMP's mpz_t format aren't optimised nor are any montgomery forms
922 cached, and on x86 it appears OpenSSL's own performance has caught up.
923 However there are likely to be other architectures where GMP could
924 provide a boost. This ENGINE is not built in by default, but it can be
925 specified at Configure time and should be accompanied by the necessary
926 linker additions, eg;
927 ./config -DOPENSSL_USE_GMP -lgmp
930 *) "openssl engine" will not display ENGINE/DSO load failure errors when
931 testing availability of engines with "-t" - the old behaviour is
932 produced by increasing the feature's verbosity with "-tt".
935 *) ECDSA routines: under certain error conditions uninitialized BN objects
936 could be freed. Solution: make sure initialization is performed early
937 enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de>
941 *) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD
942 and DH_METHOD (eg. by ENGINE implementations) to override the normal
943 software implementations. For DSA and DH, parameter generation can
944 also be overriden by providing the appropriate method callbacks.
947 *) Change the "progress" mechanism used in key-generation and
948 primality testing to functions that take a new BN_GENCB pointer in
949 place of callback/argument pairs. The new API functions have "_ex"
950 postfixes and the older functions are reimplemented as wrappers for
951 the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide
952 declarations of the old functions to help (graceful) attempts to
953 migrate to the new functions. Also, the new key-generation API
954 functions operate on a caller-supplied key-structure and return
955 success/failure rather than returning a key or NULL - this is to
956 help make "keygen" another member function of RSA_METHOD etc.
958 Example for using the new callback interface:
960 int (*my_callback)(int a, int b, BN_GENCB *cb) = ...;
964 BN_GENCB_set(&my_cb, my_callback, my_arg);
966 return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb);
967 /* For the meaning of a, b in calls to my_callback(), see the
968 * documentation of the function that calls the callback.
969 * cb will point to my_cb; my_arg can be retrieved as cb->arg.
970 * my_callback should return 1 if it wants BN_is_prime_ex()
971 * to continue, or 0 to stop.
976 *) Change the ZLIB compression method to be stateful, and make it
977 available to TLS with the number defined in
978 draft-ietf-tls-compression-04.txt.
981 *) Add the ASN.1 structures and functions for CertificatePair, which
982 is defined as follows (according to X.509_4thEditionDraftV6.pdf):
984 CertificatePair ::= SEQUENCE {
985 forward [0] Certificate OPTIONAL,
986 reverse [1] Certificate OPTIONAL,
987 -- at least one of the pair shall be present -- }
989 Also implement the PEM functions to read and write certificate
990 pairs, and defined the PEM tag as "CERTIFICATE PAIR".
992 This needed to be defined, mostly for the sake of the LDAP
993 attribute crossCertificatePair, but may prove useful elsewhere as
997 *) Make it possible to inhibit symlinking of shared libraries in
998 Makefile.shared, for Cygwin's sake.
1001 *) Extend the BIGNUM API by creating a function
1002 void BN_set_negative(BIGNUM *a, int neg);
1003 and a macro that behave like
1004 int BN_is_negative(const BIGNUM *a);
1006 to avoid the need to access 'a->neg' directly in applications.
1009 *) Implement fast modular reduction for pseudo-Mersenne primes
1010 used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
1011 EC_GROUP_new_curve_GFp() will now automatically use this
1013 [Nils Larsch <nla@trustcenter.de>]
1015 *) Add new lock type (CRYPTO_LOCK_BN).
1018 *) Change the ENGINE framework to automatically load engines
1019 dynamically from specific directories unless they could be
1020 found to already be built in or loaded. Move all the
1021 current engines except for the cryptodev one to a new
1023 The engines in engines/ are built as shared libraries if
1024 the "shared" options was given to ./Configure or ./config.
1025 Otherwise, they are inserted in libcrypto.a.
1026 /usr/local/ssl/engines is the default directory for dynamic
1027 engines, but that can be overriden at configure time through
1028 the usual use of --prefix and/or --openssldir, and at run
1029 time with the environment variable OPENSSL_ENGINES.
1030 [Geoff Thorpe and Richard Levitte]
1032 *) Add Makefile.shared, a helper makefile to build shared
1033 libraries. Addapt Makefile.org.
1036 *) Add version info to Win32 DLLs.
1037 [Peter 'Luna' Runestig" <peter@runestig.com>]
1039 *) Add new 'medium level' PKCS#12 API. Certificates and keys
1040 can be added using this API to created arbitrary PKCS#12
1041 files while avoiding the low level API.
1043 New options to PKCS12_create(), key or cert can be NULL and
1044 will then be omitted from the output file. The encryption
1045 algorithm NIDs can be set to -1 for no encryption, the mac
1046 iteration count can be set to 0 to omit the mac.
1048 Enhance pkcs12 utility by making the -nokeys and -nocerts
1049 options work when creating a PKCS#12 file. New option -nomac
1050 to omit the mac, NONE can be set for an encryption algorithm.
1051 New code is modified to use the enhanced PKCS12_create()
1052 instead of the low level API.
1055 *) Extend ASN1 encoder to support indefinite length constructed
1056 encoding. This can output sequences tags and octet strings in
1057 this form. Modify pk7_asn1.c to support indefinite length
1058 encoding. This is experimental and needs additional code to
1059 be useful, such as an ASN1 bio and some enhanced streaming
1062 Extend template encode functionality so that tagging is passed
1063 down to the template encoder.
1066 *) Let 'openssl req' fail if an argument to '-newkey' is not
1067 recognized instead of using RSA as a default.
1070 *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
1071 As these are not official, they are not included in "ALL";
1072 the "ECCdraft" ciphersuite group alias can be used to select them.
1073 [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
1075 *) Add ECDH engine support.
1076 [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
1078 *) Add ECDH in new directory crypto/ecdh/.
1079 [Douglas Stebila (Sun Microsystems Laboratories)]
1081 *) Let BN_rand_range() abort with an error after 100 iterations
1082 without success (which indicates a broken PRNG).
1085 *) Change BN_mod_sqrt() so that it verifies that the input value
1086 is really the square of the return value. (Previously,
1087 BN_mod_sqrt would show GIGO behaviour.)
1090 *) Add named elliptic curves over binary fields from X9.62, SECG,
1091 and WAP/WTLS; add OIDs that were still missing.
1093 [Sheueling Chang Shantz and Douglas Stebila
1094 (Sun Microsystems Laboratories)]
1096 *) Extend the EC library for elliptic curves over binary fields
1097 (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
1100 EC_GF2m_simple_method
1104 EC_GROUP_new_curve_GF2m
1105 EC_GROUP_set_curve_GF2m
1106 EC_GROUP_get_curve_GF2m
1107 EC_POINT_set_affine_coordinates_GF2m
1108 EC_POINT_get_affine_coordinates_GF2m
1109 EC_POINT_set_compressed_coordinates_GF2m
1111 Point compression for binary fields is disabled by default for
1112 patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
1115 As binary polynomials are represented as BIGNUMs, various members
1116 of the EC_GROUP and EC_POINT data structures can be shared
1117 between the implementations for prime fields and binary fields;
1118 the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
1119 are essentially identical to their ..._GFp counterparts.
1120 (For simplicity, the '..._GFp' prefix has been dropped from
1121 various internal method names.)
1123 An internal 'field_div' method (similar to 'field_mul' and
1124 'field_sqr') has been added; this is used only for binary fields.
1126 [Sheueling Chang Shantz and Douglas Stebila
1127 (Sun Microsystems Laboratories)]
1129 *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
1130 through methods ('mul', 'precompute_mult').
1132 The generic implementations (now internally called 'ec_wNAF_mul'
1133 and 'ec_wNAF_precomputed_mult') remain the default if these
1134 methods are undefined.
1136 [Sheueling Chang Shantz and Douglas Stebila
1137 (Sun Microsystems Laboratories)]
1139 *) New function EC_GROUP_get_degree, which is defined through
1140 EC_METHOD. For curves over prime fields, this returns the bit
1141 length of the modulus.
1143 [Sheueling Chang Shantz and Douglas Stebila
1144 (Sun Microsystems Laboratories)]
1146 *) New functions EC_GROUP_dup, EC_POINT_dup.
1147 (These simply call ..._new and ..._copy).
1149 [Sheueling Chang Shantz and Douglas Stebila
1150 (Sun Microsystems Laboratories)]
1152 *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
1153 Polynomials are represented as BIGNUMs (where the sign bit is not
1154 used) in the following functions [macros]:
1157 BN_GF2m_sub [= BN_GF2m_add]
1158 BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
1159 BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
1160 BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
1162 BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
1163 BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
1164 BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
1165 BN_GF2m_cmp [= BN_ucmp]
1167 (Note that only the 'mod' functions are actually for fields GF(2^m).
1168 BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
1170 For some functions, an the irreducible polynomial defining a
1171 field can be given as an 'unsigned int[]' with strictly
1172 decreasing elements giving the indices of those bits that are set;
1173 i.e., p[] represents the polynomial
1174 f(t) = t^p[0] + t^p[1] + ... + t^p[k]
1176 p[0] > p[1] > ... > p[k] = 0.
1177 This applies to the following functions:
1182 BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
1183 BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
1185 BN_GF2m_mod_sqrt_arr
1186 BN_GF2m_mod_solve_quad_arr
1190 Conversion can be performed by the following functions:
1195 bntest.c has additional tests for binary polynomial arithmetic.
1197 Two implementations for BN_GF2m_mod_div() are available.
1198 The default algorithm simply uses BN_GF2m_mod_inv() and
1199 BN_GF2m_mod_mul(). The alternative algorithm is compiled in only
1200 if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
1201 copyright notice in crypto/bn/bn_gf2m.c before enabling it).
1203 [Sheueling Chang Shantz and Douglas Stebila
1204 (Sun Microsystems Laboratories)]
1206 *) Add new error code 'ERR_R_DISABLED' that can be used when some
1207 functionality is disabled at compile-time.
1208 [Douglas Stebila <douglas.stebila@sun.com>]
1210 *) Change default behaviour of 'openssl asn1parse' so that more
1211 information is visible when viewing, e.g., a certificate:
1213 Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
1214 mode the content of non-printable OCTET STRINGs is output in a
1215 style similar to INTEGERs, but with '[HEX DUMP]' prepended to
1216 avoid the appearance of a printable string.
1217 [Nils Larsch <nla@trustcenter.de>]
1219 *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
1221 EC_GROUP_set_asn1_flag()
1222 EC_GROUP_get_asn1_flag()
1223 EC_GROUP_set_point_conversion_form()
1224 EC_GROUP_get_point_conversion_form()
1225 These control ASN1 encoding details:
1226 - Curves (i.e., groups) are encoded explicitly unless asn1_flag
1227 has been set to OPENSSL_EC_NAMED_CURVE.
1228 - Points are encoded in uncompressed form by default; options for
1229 asn1_for are as for point2oct, namely
1230 POINT_CONVERSION_COMPRESSED
1231 POINT_CONVERSION_UNCOMPRESSED
1232 POINT_CONVERSION_HYBRID
1234 Also add 'seed' and 'seed_len' members to EC_GROUP with access
1237 EC_GROUP_get0_seed()
1238 EC_GROUP_get_seed_len()
1239 This is used only for ASN1 purposes (so far).
1240 [Nils Larsch <nla@trustcenter.de>]
1242 *) Add 'field_type' member to EC_METHOD, which holds the NID
1243 of the appropriate field type OID. The new function
1244 EC_METHOD_get_field_type() returns this value.
1245 [Nils Larsch <nla@trustcenter.de>]
1250 EC_POINT_point2hex()
1251 EC_POINT_hex2point()
1252 providing useful interfaces to EC_POINT_point2oct() and
1253 EC_POINT_oct2point().
1254 [Nils Larsch <nla@trustcenter.de>]
1256 *) Change internals of the EC library so that the functions
1257 EC_GROUP_set_generator()
1258 EC_GROUP_get_generator()
1259 EC_GROUP_get_order()
1260 EC_GROUP_get_cofactor()
1261 are implemented directly in crypto/ec/ec_lib.c and not dispatched
1262 to methods, which would lead to unnecessary code duplication when
1263 adding different types of curves.
1264 [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
1266 *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
1267 arithmetic, and such that modified wNAFs are generated
1268 (which avoid length expansion in many cases).
1271 *) Add a function EC_GROUP_check_discriminant() (defined via
1272 EC_METHOD) that verifies that the curve discriminant is non-zero.
1274 Add a function EC_GROUP_check() that makes some sanity tests
1275 on a EC_GROUP, its generator and order. This includes
1276 EC_GROUP_check_discriminant().
1277 [Nils Larsch <nla@trustcenter.de>]
1279 *) Add ECDSA in new directory crypto/ecdsa/.
1281 Add applications 'openssl ecparam' and 'openssl ecdsa'
1282 (these are based on 'openssl dsaparam' and 'openssl dsa').
1284 ECDSA support is also included in various other files across the
1285 library. Most notably,
1286 - 'openssl req' now has a '-newkey ecdsa:file' option;
1287 - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
1288 - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
1289 d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
1290 them suitable for ECDSA where domain parameters must be
1291 extracted before the specific public key;
1292 - ECDSA engine support has been added.
1293 [Nils Larsch <nla@trustcenter.de>]
1295 *) Include some named elliptic curves, and add OIDs from X9.62,
1296 SECG, and WAP/WTLS. Each curve can be obtained from the new
1298 EC_GROUP_new_by_curve_name(),
1299 and the list of available named curves can be obtained with
1300 EC_get_builtin_curves().
1301 Also add a 'curve_name' member to EC_GROUP objects, which can be

1305 [Nils Larsch <larsch@trustcenter.de, Bodo Moeller]
1307 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
1308 was actually never needed) and in BN_mul(). The removal in BN_mul()
1309 required a small change in bn_mul_part_recursive() and the addition
1310 of the functions bn_cmp_part_words(), bn_sub_part_words() and
1311 bn_add_part_words(), which do the same thing as bn_cmp_words(),
1312 bn_sub_words() and bn_add_words() except they take arrays with

1318 *) Change the Unix randomness entropy gathering to use poll() when
1319 possible instead of select(), since the latter has some
1320 undesirable limitations.
1321 [Darryl Miles via Richard Levitte and Bodo Moeller]
1323 *) Disable rogue ciphersuites:
1325 - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
1326 - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
1327 - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
1329 The latter two were purportedly from
1330 draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
1333 Also deactive the remaining ciphersuites from
1334 draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as
1335 unofficial, and the ID has long expired.
1338 *) Fix RSA blinding Heisenbug (problems sometimes occured on
1339 dual-core machines) and other potential thread-safety issues.
1342 Changes between 0.9.7i and 0.9.7j [04 May 2006]
1344 *) Adapt fipsld and the build system to link against the validated FIPS
1345 module in FIPS mode.
1348 *) Fixes for VC++ 2005 build under Windows.
1351 *) Add new Windows build target VC-32-GMAKE for VC++. This uses GNU make
1352 from a Windows bash shell such as MSYS. It is autodetected from the
1353 "config" script when run from a VC++ environment. Modify standard VC++
1354 build to use fipscanister.o from the GNU make build.
1357 Changes between 0.9.7h and 0.9.7i [14 Oct 2005]
1359 *) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS.
1360 The value now differs depending on if you build for FIPS or not.
1361 BEWARE! A program linked with a shared FIPSed libcrypto can't be
1362 safely run with a non-FIPSed libcrypto, as it may crash because of
1363 the difference induced by this change.
1366 Changes between 0.9.7g and 0.9.7h [11 Oct 2005]
1368 *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
1369 (part of SSL_OP_ALL). This option used to disable the
1370 countermeasure against man-in-the-middle protocol-version
1371 rollback in the SSL 2.0 server implementation, which is a bad
1372 idea. (CVE-2005-2969)
1374 [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
1375 for Information Security, National Institute of Advanced Industrial
1376 Science and Technology [AIST], Japan)]
1378 *) Minimal support for X9.31 signatures and PSS padding modes. This is
1379 mainly for FIPS compliance and not fully integrated at this stage.
1382 *) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform
1383 the exponentiation using a fixed-length exponent. (Otherwise,
1384 the information leaked through timing could expose the secret key
1385 after many signatures; cf. Bleichenbacher's attack on DSA with
1389 *) Make a new fixed-window mod_exp implementation the default for
1390 RSA, DSA, and DH private-key operations so that the sequence of
1391 squares and multiplies and the memory access pattern are
1392 independent of the particular secret key. This will mitigate
1393 cache-timing and potential related attacks.
1395 BN_mod_exp_mont_consttime() is the new exponentiation implementation,
1396 and this is automatically used by BN_mod_exp_mont() if the new flag
1397 BN_FLG_EXP_CONSTTIME is set for the exponent. RSA, DSA, and DH
1398 will use this BN flag for private exponents unless the flag
1399 RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or
1400 DH_FLAG_NO_EXP_CONSTTIME, respectively, is set.
1402 [Matthew D Wood (Intel Corp), with some changes by Bodo Moeller]
1404 *) Change the client implementation for SSLv23_method() and
1405 SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0
1406 Client Hello message format if the SSL_OP_NO_SSLv2 option is set.
1407 (Previously, the SSL 2.0 backwards compatible Client Hello
1408 message format would be used even with SSL_OP_NO_SSLv2.)
1411 *) Add support for smime-type MIME parameter in S/MIME messages which some
1415 *) New function BN_MONT_CTX_set_locked() to set montgomery parameters in
1416 a threadsafe manner. Modify rsa code to use new function and add calls
1417 to dsa and dh code (which had race conditions before).
1420 *) Include the fixed error library code in the C error file definitions
1421 instead of fixing them up at runtime. This keeps the error code
1422 structures constant.
1425 Changes between 0.9.7f and 0.9.7g [11 Apr 2005]
1427 [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after
1430 *) Fixes for newer kerberos headers. NB: the casts are needed because
1431 the 'length' field is signed on one version and unsigned on another
1432 with no (?) obvious way to tell the difference, without these VC++
1433 complains. Also the "definition" of FAR (blank) is no longer included
1434 nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up
1435 some needed definitions.
1438 *) Undo Cygwin change.
1441 *) Added support for proxy certificates according to RFC 3820.
1442 Because they may be a security thread to unaware applications,
1443 they must be explicitely allowed in run-time. See
1444 docs/HOWTO/proxy_certificates.txt for further information.
1447 Changes between 0.9.7e and 0.9.7f [22 Mar 2005]
1449 *) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating
1450 server and client random values. Previously
1451 (SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in
1452 less random data when sizeof(time_t) > 4 (some 64 bit platforms).
1454 This change has negligible security impact because:
1456 1. Server and client random values still have 24 bytes of pseudo random
1459 2. Server and client random values are sent in the clear in the initial
1462 3. The master secret is derived using the premaster secret (48 bytes in
1463 size for static RSA ciphersuites) as well as client server and random
1466 The OpenSSL team would like to thank the UK NISCC for bringing this issue
1469 [Stephen Henson, reported by UK NISCC]
1471 *) Use Windows randomness collection on Cygwin.
1474 *) Fix hang in EGD/PRNGD query when communication socket is closed
1475 prematurely by EGD/PRNGD.
1476 [Darren Tucker <dtucker@zip.com.au> via Lutz Jänicke, resolves #1014]
1478 *) Prompt for pass phrases when appropriate for PKCS12 input format.
1481 *) Back-port of selected performance improvements from development
1482 branch, as well as improved support for PowerPC platforms.
1485 *) Add lots of checks for memory allocation failure, error codes to indicate
1486 failure and freeing up memory if a failure occurs.
1487 [Nauticus Networks SSL Team <openssl@nauticusnet.com>, Steve Henson]
1489 *) Add new -passin argument to dgst.
1492 *) Perform some character comparisons of different types in X509_NAME_cmp:
1493 this is needed for some certificates that reencode DNs into UTF8Strings
1494 (in violation of RFC3280) and can't or wont issue name rollover
1498 *) Make an explicit check during certificate validation to see that
1499 the CA setting in each certificate on the chain is correct. As a
1500 side effect always do the following basic checks on extensions,
1501 not just when there's an associated purpose to the check:
1503 - if there is an unhandled critical extension (unless the user
1504 has chosen to ignore this fault)
1505 - if the path length has been exceeded (if one is set at all)
1506 - that certain extensions fit the associated purpose (if one has
1510 Changes between 0.9.7d and 0.9.7e [25 Oct 2004]
1512 *) Avoid a race condition when CRLs are checked in a multi threaded
1513 environment. This would happen due to the reordering of the revoked
1514 entries during signature checking and serial number lookup. Now the
1515 encoding is cached and the serial number sort performed under a lock.
1516 Add new STACK function sk_is_sorted().
1519 *) Add Delta CRL to the extension code.
1522 *) Various fixes to s3_pkt.c so alerts are sent properly.
1523 [David Holmes <d.holmes@f5.com>]
1525 *) Reduce the chances of duplicate issuer name and serial numbers (in
1526 violation of RFC3280) using the OpenSSL certificate creation utilities.
1527 This is done by creating a random 64 bit value for the initial serial
1528 number when a serial number file is created or when a self signed
1529 certificate is created using 'openssl req -x509'. The initial serial
1530 number file is created using 'openssl x509 -next_serial' in CA.pl
1531 rather than being initialized to 1.
1534 Changes between 0.9.7c and 0.9.7d [17 Mar 2004]
1536 *) Fix null-pointer assignment in do_change_cipher_spec() revealed
1537 by using the Codenomicon TLS Test Tool (CVE-2004-0079)
1538 [Joe Orton, Steve Henson]
1540 *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites
1542 [Joe Orton, Steve Henson]
1544 *) Make it possible to have multiple active certificates with the same
1545 subject in the CA index file. This is done only if the keyword
1546 'unique_subject' is set to 'no' in the main CA section (default
1547 if 'CA_default') of the configuration file. The value is saved
1548 with the database itself in a separate index attribute file,
1549 named like the index file with '.attr' appended to the name.
1552 *) X509 verify fixes. Disable broken certificate workarounds when
1553 X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if
1554 keyUsage extension present. Don't accept CRLs with unhandled critical
1555 extensions: since verify currently doesn't process CRL extensions this
1556 rejects a CRL with *any* critical extensions. Add new verify error codes
1560 *) When creating an OCSP nonce use an OCTET STRING inside the extnValue.
1561 A clarification of RFC2560 will require the use of OCTET STRINGs and
1562 some implementations cannot handle the current raw format. Since OpenSSL
1563 copies and compares OCSP nonces as opaque blobs without any attempt at
1564 parsing them this should not create any compatibility issues.
1567 *) New md flag EVP_MD_CTX_FLAG_REUSE this allows md_data to be reused when
1568 calling EVP_MD_CTX_copy_ex() to avoid calling OPENSSL_malloc(). Without
1569 this HMAC (and other) operations are several times slower than OpenSSL

1581 *) Fix various bugs revealed by running the NISCC test suite:
1583 Stop out of bounds reads in the ASN1 code when presented with
1584 invalid tags (CVE-2003-0543 and CVE-2003-0544).
1586 Free up ASN1_TYPE correctly if ANY type is invalid (CVE-2003-0545).
1588 If verify callback ignores invalid public key errors don't try to check
1589 certificate signature with the NULL public key.
1593 *) New -ignore_err option in ocsp application to stop the server
1594 exiting on the first error in a request.
1597 *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
1598 if the server requested one: as stated in TLS 1.0 and SSL 3.0
1602 *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
1603 extra data after the compression methods not only for TLS 1.0
1604 but also for SSL 3.0 (as required by the specification).
1605 [Bodo Moeller; problem pointed out by Matthias Loepfe]
1607 *) Change X509_certificate_type() to mark the key as exported/exportable
1608 when it's 512 *bits* long, not 512 bytes.
1611 *) Change AES_cbc_encrypt() so it outputs exact multiple of
1612 blocks during encryption.
1615 *) Various fixes to base64 BIO and non blocking I/O. On write
1616 flushes were not handled properly if the BIO retried. On read
1617 data was not being buffered properly and had various logic bugs.
1618 This also affects blocking I/O when the data being decoded is a
1622 *) Various S/MIME bugfixes and compatibility changes:
1623 output correct application/pkcs7 MIME type if
1624 PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures.
1625 Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening
1626 of files as .eml work). Correctly handle very long lines in MIME
1630 Changes between 0.9.7a and 0.9.7b [10 Apr 2003]
1632 *) Countermeasure against the Klima-Pokorny-Rosa extension of
1633 Bleichbacher's attack on PKCS #1 v1.5 padding: treat
1634 a protocol version number mismatch like a decryption error
1635 in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
1638 *) Turn on RSA blinding by default in the default implementation
1639 to avoid a timing attack. Applications that don't want it can call
1640 RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
1641 They would be ill-advised to do so in most cases.
1642 [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
1644 *) Change RSA blinding code so that it works when the PRNG is not
1645 seeded (in this case, the secret RSA exponent is abused as
1646 an unpredictable seed -- if it is not unpredictable, there
1647 is no point in blinding anyway). Make RSA blinding thread-safe
1648 by remembering the creator's thread ID in rsa->blinding and
1649 having all other threads use local one-time blinding factors
1650 (this requires more computation than sharing rsa->blinding, but
1651 avoids excessive locking; and if an RSA object is not shared
1652 between threads, blinding will still be very fast).
1655 *) Fixed a typo bug that would cause ENGINE_set_default() to set an
1656 ENGINE as defaults for all supported algorithms irrespective of
1657 the 'flags' parameter. 'flags' is now honoured, so applications
1658 should make sure they are passing it correctly.
1661 *) Target "mingw" now allows native Windows code to be generated in
1662 the Cygwin environment as well as with the MinGW compiler.
1665 Changes between 0.9.7 and 0.9.7a [19 Feb 2003]
1667 *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
1668 via timing by performing a MAC computation even if incorrrect
1669 block cipher padding has been found. This is a countermeasure
1670 against active attacks where the attacker has to distinguish
1671 between bad padding and a MAC verification error. (CVE-2003-0078)

1674 Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
1675 Martin Vuagnoux (EPFL, Ilion)]
1677 *) Make the no-err option work as intended. The intention with no-err
1678 is not to have the whole error stack handling routines removed from
1679 libcrypto, it's only intended to remove all the function name and
1680 reason texts, thereby removing some of the footprint that may not
1681 be interesting if those errors aren't displayed anyway.
1683 NOTE: it's still possible for any application or module to have it's
1684 own set of error texts inserted. The routines are there, just not
1685 used by default when no-err is given.
1688 *) Add support for FreeBSD on IA64.
1689 [dirk.meyer@dinoex.sub.org via Richard Levitte, resolves #454]
1691 *) Adjust DES_cbc_cksum() so it returns the same value as the MIT
1692 Kerberos function mit_des_cbc_cksum(). Before this change,
1693 the value returned by DES_cbc_cksum() was like the one from
1694 mit_des_cbc_cksum(), except the bytes were swapped.
1695 [Kevin Greaney <Kevin.Greaney@hp.com> and Richard Levitte]
1697 *) Allow an application to disable the automatic SSL chain building.
1698 Before this a rather primitive chain build was always performed in
1699 ssl3_output_cert_chain(): an application had no way to send the
1700 correct chain if the automatic operation produced an incorrect result.
1702 Now the chain builder is disabled if either:
1704 1. Extra certificates are added via SSL_CTX_add_extra_chain_cert().
1706 2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set.
1708 The reasoning behind this is that an application would not want the
1709 auto chain building to take place if extra chain certificates are
1710 present and it might also want a means of sending no additional
1711 certificates (for example the chain has two certificates and the
1715 *) Add the possibility to build without the ENGINE framework.
1716 [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
1718 *) Under Win32 gmtime() can return NULL: check return value in
1719 OPENSSL_gmtime(). Add error code for case where gmtime() fails.
1722 *) DSA routines: under certain error conditions uninitialized BN objects
1723 could be freed. Solution: make sure initialization is performed early
1724 enough. (Reported and fix supplied by Ivan D Nestlerode <nestler@MIT.EDU>,
1725 Nils Larsch <nla@trustcenter.de> via PR#459)
1728 *) Another fix for SSLv2 session ID handling: the session ID was incorrectly
1729 checked on reconnect on the client side, therefore session resumption
1730 could still fail with a "ssl session id is different" error. This
1731 behaviour is masked when SSL_OP_ALL is used due to
1732 SSL_OP_MICROSOFT_SESS_ID_BUG being set.
1733 Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
1734 followup to PR #377.
1737 *) IA-32 assembler support enhancements: unified ELF targets, support
1738 for SCO/Caldera platforms, fix for Cygwin shared build.
1741 *) Add support for FreeBSD on sparc64. As a consequence, support for
1742 FreeBSD on non-x86 processors is separate from x86 processors on
1743 the config script, much like the NetBSD support.

1873 [Ben Laurie (CHATS)]
1875 *) Eliminate unused and dangerous structure, KSSL_ERR.
1876 [Ben Laurie (CHATS)]
1878 *) Protect against overlong session ID context length in an encoded
1879 session object. Since these are local, this does not appear to be
1881 [Ben Laurie (CHATS)]
1883 *) Change from security patch (see 0.9.6e below) that did not affect
1884 the 0.9.6 release series:
1886 Remote buffer overflow in SSL3 protocol - an attacker could
1887 supply an oversized master key in Kerberos-enabled versions.
1889 [Ben Laurie (CHATS)]
1891 *) Change the SSL kerb5 codes to match RFC 2712.
1894 *) Make -nameopt work fully for req and add -reqopt switch.
1895 [Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
1897 *) The "block size" for block ciphers in CFB and OFB mode should be 1.
1898 [Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
1900 *) Make sure tests can be performed even if the corresponding algorithms
1901 have been removed entirely. This was also the last step to make
1902 OpenSSL compilable with DJGPP under all reasonable conditions.
1903 [Richard Levitte, Doug Kaufman <dkaufman@rahul.net>]
1905 *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT
1906 to allow version independent disabling of normally unselected ciphers,
1907 which may be activated as a side-effect of selecting a single cipher.
1909 (E.g., cipher list string "RSA" enables ciphersuites that are left
1910 out of "ALL" because they do not provide symmetric encryption.
1911 "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.)
1912 [Lutz Jaenicke, Bodo Moeller]
1914 *) Add appropriate support for separate platform-dependent build
1915 directories. The recommended way to make a platform-dependent
1916 build directory is the following (tested on Linux), maybe with
1919 # Place yourself outside of the OpenSSL source tree. In
1920 # this example, the environment variable OPENSSL_SOURCE
1921 # is assumed to contain the absolute OpenSSL source directory.
1922 mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
1923 cd objtree/"`uname -s`-`uname -r`-`uname -m`"
1924 (cd $OPENSSL_SOURCE; find . -type f) | while read F; do
1925 mkdir -p `dirname $F`
1926 ln -s $OPENSSL_SOURCE/$F $F
1929 To be absolutely sure not to disturb the source tree, a "make clean"
1930 is a good thing. If it isn't successfull, don't worry about it,
1931 it probably means the source directory is very clean.
1934 *) Make sure any ENGINE control commands make local copies of string
1935 pointers passed to them whenever necessary. Otherwise it is possible
1936 the caller may have overwritten (or deallocated) the original string
1937 data when a later ENGINE operation tries to use the stored values.
1938 [Götz Babin-Ebell <babinebell@trustcenter.de>]
1940 *) Improve diagnostics in file reading and command-line digests.
1941 [Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>]
1943 *) Add AES modes CFB and OFB to the object database. Correct an
1944 error in AES-CFB decryption.
1947 *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
1948 allows existing EVP_CIPHER_CTX structures to be reused after
1949 calling EVP_*Final(). This behaviour is used by encryption
1950 BIOs and some applications. This has the side effect that
1951 applications must explicitly clean up cipher contexts with
1952 EVP_CIPHER_CTX_cleanup() or they will leak memory.
1955 *) Check the values of dna and dnb in bn_mul_recursive before calling
1956 bn_mul_comba (a non zero value means the a or b arrays do not contain
1957 n2 elements) and fallback to bn_mul_normal if either is not zero.
1960 *) Fix escaping of non-ASCII characters when using the -subj option
1961 of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
1964 *) Make object definitions compliant to LDAP (RFC2256): SN is the short
1965 form for "surname", serialNumber has no short form.
1966 Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
1967 therefore remove "mail" short name for "internet 7".
1968 The OID for unique identifiers in X509 certificates is
1969 x500UniqueIdentifier, not uniqueIdentifier.
1970 Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>)
1973 *) Add an "init" command to the ENGINE config module and auto initialize
1974 ENGINEs. Without any "init" command the ENGINE will be initialized
1975 after all ctrl commands have been executed on it. If init=1 the
1976 ENGINE is initailized at that point (ctrls before that point are run
1977 on the uninitialized ENGINE and after on the initialized one). If
1978 init=0 then the ENGINE will not be iniatialized at all.
1981 *) Fix the 'app_verify_callback' interface so that the user-defined
1982 argument is actually passed to the callback: In the
1983 SSL_CTX_set_cert_verify_callback() prototype, the callback
1984 declaration has been changed from
1987 int (*cb)(X509_STORE_CTX *,void *);
1988 in ssl_verify_cert_chain (ssl/ssl_cert.c), the call
1989 i=s->ctx->app_verify_callback(&ctx)
1990 has been changed into
1991 i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg).
1993 To update applications using SSL_CTX_set_cert_verify_callback(),
1994 a dummy argument can be added to their callback functions.
1995 [D. K. Smetters <smetters@parc.xerox.com>]
1997 *) Added the '4758cca' ENGINE to support IBM 4758 cards.
1998 [Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe]
2000 *) Add and OPENSSL_LOAD_CONF define which will cause
2001 OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
2002 This allows older applications to transparently support certain
2003 OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.
2004 Two new functions OPENSSL_add_all_algorithms_noconf() which will never
2005 load the config file and OPENSSL_add_all_algorithms_conf() which will
2006 always load it have also been added.
2009 *) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
2010 Adjust NIDs and EVP layer.
2011 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
2013 *) Config modules support in openssl utility.
2015 Most commands now load modules from the config file,
2016 though in a few (such as version) this isn't done
2017 because it couldn't be used for anything.
2019 In the case of ca and req the config file used is
2020 the same as the utility itself: that is the -config
2021 command line option can be used to specify an
2025 *) Move default behaviour from OPENSSL_config(). If appname is NULL
2026 use "openssl_conf" if filename is NULL use default openssl config file.
2029 *) Add an argument to OPENSSL_config() to allow the use of an alternative
2030 config section name. Add a new flag to tolerate a missing config file
2031 and move code to CONF_modules_load_file().
2034 *) Support for crypto accelerator cards from Accelerated Encryption
2035 Processing, www.aep.ie. (Use engine 'aep')
2036 The support was copied from 0.9.6c [engine] and adapted/corrected
2037 to work with the new engine framework.
2038 [AEP Inc. and Richard Levitte]
2040 *) Support for SureWare crypto accelerator cards from Baltimore
2041 Technologies. (Use engine 'sureware')
2042 The support was copied from 0.9.6c [engine] and adapted
2043 to work with the new engine framework.
2046 *) Have the CHIL engine fork-safe (as defined by nCipher) and actually
2047 make the newer ENGINE framework commands for the CHIL engine work.
2048 [Toomas Kiisk <vix@cyber.ee> and Richard Levitte]
2050 *) Make it possible to produce shared libraries on ReliantUNIX.
2051 [Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte]
2053 *) Add the configuration target debug-linux-ppro.
2054 Make 'openssl rsa' use the general key loading routines
2055 implemented in apps.c, and make those routines able to
2056 handle the key format FORMAT_NETSCAPE and the variant
2058 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
2060 *) Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
2061 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
2063 *) Add -keyform to rsautl, and document -engine.
2064 [Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>]
2066 *) Change BIO_new_file (crypto/bio/bss_file.c) to use new
2067 BIO_R_NO_SUCH_FILE error code rather than the generic
2068 ERR_R_SYS_LIB error code if fopen() fails with ENOENT.
2071 *) Add new functions
2073 ERR_peek_last_error_line
2074 ERR_peek_last_error_line_data.
2075 These are similar to
2078 ERR_peek_error_line_data,
2079 but report on the latest error recorded rather than the first one
2080 still in the error queue.
2081 [Ben Laurie, Bodo Moeller]
2083 *) default_algorithms option in ENGINE config module. This allows things
2085 default_algorithms = ALL
2086 default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS
2089 *) Prelminary ENGINE config module.
2092 *) New experimental application configuration code.
2095 *) Change the AES code to follow the same name structure as all other
2096 symmetric ciphers, and behave the same way. Move everything to
2097 the directory crypto/aes, thereby obsoleting crypto/rijndael.
2098 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
2100 *) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c.
2101 [Ben Laurie and Theo de Raadt]
2103 *) Add option to output public keys in req command.
2104 [Massimiliano Pala madwolf@openca.org]
2106 *) Use wNAFs in EC_POINTs_mul() for improved efficiency
2107 (up to about 10% better than before for P-192 and P-224).
2110 *) New functions/macros
2112 SSL_CTX_set_msg_callback(ctx, cb)
2113 SSL_CTX_set_msg_callback_arg(ctx, arg)
2114 SSL_set_msg_callback(ssl, cb)
2115 SSL_set_msg_callback_arg(ssl, arg)
2117 to request calling a callback function
2119 void cb(int write_p, int version, int content_type,
2120 const void *buf, size_t len, SSL *ssl, void *arg)
2122 whenever a protocol message has been completely received
2123 (write_p == 0) or sent (write_p == 1). Here 'version' is the
2124 protocol version according to which the SSL library interprets
2125 the current protocol message (SSL2_VERSION, SSL3_VERSION, or
2126 TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or
2127 the content type as defined in the SSL 3.0/TLS 1.0 protocol
2128 specification (change_cipher_spec(20), alert(21), handshake(22)).
2129 'buf' and 'len' point to the actual message, 'ssl' to the
2130 SSL object, and 'arg' is the application-defined value set by
2131 SSL[_CTX]_set_msg_callback_arg().
2133 'openssl s_client' and 'openssl s_server' have new '-msg' options
2134 to enable a callback that displays all protocol messages.
2137 *) Change the shared library support so shared libraries are built as
2138 soon as the corresponding static library is finished, and thereby get
2139 openssl and the test programs linked against the shared library.
2140 This still only happens when the keyword "shard" has been given to
2141 the configuration scripts.
2143 NOTE: shared library support is still an experimental thing, and
2144 backward binary compatibility is still not guaranteed.
2145 ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte]
2147 *) Add support for Subject Information Access extension.
2148 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
2150 *) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero
2151 additional bytes when new memory had to be allocated, not just
2152 when reusing an existing buffer.
2155 *) New command line and configuration option 'utf8' for the req command.
2156 This allows field values to be specified as UTF8 strings.
2159 *) Add -multi and -mr options to "openssl speed" - giving multiple parallel
2160 runs for the former and machine-readable output for the latter.
2163 *) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion
2164 of the e-mail address in the DN (i.e., it will go into a certificate
2165 extension only). The new configuration file option 'email_in_dn = no'
2166 has the same effect.
2167 [Massimiliano Pala madwolf@openca.org]
2169 *) Change all functions with names starting with des_ to be starting
2170 with DES_ instead. Add wrappers that are compatible with libdes,
2171 but are named _ossl_old_des_*. Finally, add macros that map the
2172 des_* symbols to the corresponding _ossl_old_des_* if libdes
2173 compatibility is desired. If OpenSSL 0.9.6c compatibility is
2174 desired, the des_* symbols will be mapped to DES_*, with one
2177 Since we provide two compatibility mappings, the user needs to
2178 define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes
2179 compatibility is desired. The default (i.e., when that macro
2180 isn't defined) is OpenSSL 0.9.6c compatibility.
2182 There are also macros that enable and disable the support of old
2183 des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT
2184 and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those
2185 are defined, the default will apply: to support the old des routines.
2187 In either case, one must include openssl/des.h to get the correct
2188 definitions. Do not try to just include openssl/des_old.h, that
2191 NOTE: This is a major break of an old API into a new one. Software
2192 authors are encouraged to switch to the DES_ style functions. Some
2193 time in the future, des_old.h and the libdes compatibility functions
2194 will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the
2195 default), and then completely removed.
2198 *) Test for certificates which contain unsupported critical extensions.
2199 If such a certificate is found during a verify operation it is
2200 rejected by default: this behaviour can be overridden by either
2201 handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
2202 by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
2203 X509_supported_extension() has also been added which returns 1 if a
2204 particular extension is supported.
2207 *) Modify the behaviour of EVP cipher functions in similar way to digests
2208 to retain compatibility with existing code.
2211 *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain
2212 compatibility with existing code. In particular the 'ctx' parameter does
2213 not have to be to be initialized before the call to EVP_DigestInit() and
2214 it is tidied up after a call to EVP_DigestFinal(). New function
2215 EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
2216 EVP_MD_CTX_copy() changed to not require the destination to be
2217 initialized valid and new function EVP_MD_CTX_copy_ex() added which
2218 requires the destination to be valid.
2220 Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
2221 EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
2224 *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
2225 so that complete 'Handshake' protocol structures are kept in memory
2226 instead of overwriting 'msg_type' and 'length' with 'body' data.
2229 *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
2230 [Massimo Santin via Richard Levitte]
2232 *) Major restructuring to the underlying ENGINE code. This includes
2233 reduction of linker bloat, separation of pure "ENGINE" manipulation
2234 (initialisation, etc) from functionality dealing with implementations
2235 of specific crypto iterfaces. This change also introduces integrated
2236 support for symmetric ciphers and digest implementations - so ENGINEs
2237 can now accelerate these by providing EVP_CIPHER and EVP_MD
2238 implementations of their own. This is detailed in crypto/engine/README
2239 as it couldn't be adequately described here. However, there are a few
2240 API changes worth noting - some RSA, DSA, DH, and RAND functions that
2241 were changed in the original introduction of ENGINE code have now
2242 reverted back - the hooking from this code to ENGINE is now a good
2243 deal more passive and at run-time, operations deal directly with
2244 RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
2245 dereferencing through an ENGINE pointer any more. Also, the ENGINE
2246 functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
2247 they were not being used by the framework as there is no concept of a
2248 BIGNUM_METHOD and they could not be generalised to the new
2249 'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
2250 ENGINE_cpy() has been removed as it cannot be consistently defined in
2254 *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
2257 *) Change mkdef.pl to sort symbols that get the same entry number,
2258 and make sure the automatically generated functions ERR_load_*
2259 become part of libeay.num as well.
2262 *) New function SSL_renegotiate_pending(). This returns true once
2263 renegotiation has been requested (either SSL_renegotiate() call
2264 or HelloRequest/ClientHello receveived from the peer) and becomes
2265 false once a handshake has been completed.
2266 (For servers, SSL_renegotiate() followed by SSL_do_handshake()
2267 sends a HelloRequest, but does not ensure that a handshake takes
2268 place. SSL_renegotiate_pending() is useful for checking if the
2269 client has followed the request.)
2272 *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
2273 By default, clients may request session resumption even during
2274 renegotiation (if session ID contexts permit); with this option,
2275 session resumption is possible only in the first handshake.
2277 SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes
2278 more bits available for options that should not be part of
2279 SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION).
2282 *) Add some demos for certificate and certificate request creation.
2285 *) Make maximum certificate chain size accepted from the peer application
2286 settable (SSL*_get/set_max_cert_list()), as proposed by
2287 "Douglas E. Engert" <deengert@anl.gov>.
2290 *) Add support for shared libraries for Unixware-7
2291 (Boyd Lynn Gerber <gerberb@zenez.com>).
2294 *) Add a "destroy" handler to ENGINEs that allows structural cleanup to
2295 be done prior to destruction. Use this to unload error strings from
2296 ENGINEs that load their own error strings. NB: This adds two new API
2297 functions to "get" and "set" this destroy handler in an ENGINE.
2300 *) Alter all existing ENGINE implementations (except "openssl" and
2301 "openbsd") to dynamically instantiate their own error strings. This
2302 makes them more flexible to be built both as statically-linked ENGINEs
2303 and self-contained shared-libraries loadable via the "dynamic" ENGINE.
2304 Also, add stub code to each that makes building them as self-contained
2305 shared-libraries easier (see README.ENGINE).
2308 *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
2309 implementations into applications that are completely implemented in
2310 self-contained shared-libraries. The "dynamic" ENGINE exposes control
2311 commands that can be used to configure what shared-library to load and
2312 to control aspects of the way it is handled. Also, made an update to
2313 the README.ENGINE file that brings its information up-to-date and
2314 provides some information and instructions on the "dynamic" ENGINE
2315 (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
2318 *) Make it possible to unload ranges of ERR strings with a new
2319 "ERR_unload_strings" function.
2322 *) Add a copy() function to EVP_MD.
2325 *) Make EVP_MD routines take a context pointer instead of just the
2326 md_data void pointer.
2329 *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
2330 that the digest can only process a single chunk of data
2331 (typically because it is provided by a piece of
2332 hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
2333 is only going to provide a single chunk of data, and hence the
2334 framework needn't accumulate the data for oneshot drivers.
2337 *) As with "ERR", make it possible to replace the underlying "ex_data"
2338 functions. This change also alters the storage and management of global
2339 ex_data state - it's now all inside ex_data.c and all "class" code (eg.
2340 RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
2341 index counters. The API functions that use this state have been changed
2342 to take a "class_index" rather than pointers to the class's local STACK
2343 and counter, and there is now an API function to dynamically create new
2344 classes. This centralisation allows us to (a) plug a lot of the
2345 thread-safety problems that existed, and (b) makes it possible to clean
2346 up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
2347 such data would previously have always leaked in application code and
2348 workarounds were in place to make the memory debugging turn a blind eye
2349 to it. Application code that doesn't use this new function will still
2350 leak as before, but their memory debugging output will announce it now
2351 rather than letting it slide.
2353 Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
2354 induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
2355 has a return value to indicate success or failure.
2358 *) Make it possible to replace the underlying "ERR" functions such that the
2359 global state (2 LHASH tables and 2 locks) is only used by the "default"
2360 implementation. This change also adds two functions to "get" and "set"
2361 the implementation prior to it being automatically set the first time
2362 any other ERR function takes place. Ie. an application can call "get",
2363 pass the return value to a module it has just loaded, and that module
2364 can call its own "set" function using that value. This means the
2365 module's "ERR" operations will use (and modify) the error state in the
2366 application and not in its own statically linked copy of OpenSSL code.
2369 *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
2370 reference counts. This performs normal REF_PRINT/REF_CHECK macros on
2371 the operation, and provides a more encapsulated way for external code
2372 (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
2373 to use these functions rather than manually incrementing the counts.
2375 Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
2378 *) Add EVP test program.
2381 *) Add symmetric cipher support to ENGINE. Expect the API to change!
2384 *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
2385 X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
2386 X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
2387 These allow a CRL to be built without having to access X509_CRL fields
2388 directly. Modify 'ca' application to use new functions.
2391 *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
2392 bug workarounds. Rollback attack detection is a security feature.
2393 The problem will only arise on OpenSSL servers when TLSv1 is not
2394 available (sslv3_server_method() or SSL_OP_NO_TLSv1).
2395 Software authors not wanting to support TLSv1 will have special reasons
2396 for their choice and can explicitly enable this option.
2397 [Bodo Moeller, Lutz Jaenicke]
2399 *) Rationalise EVP so it can be extended: don't include a union of
2400 cipher/digest structures, add init/cleanup functions for EVP_MD_CTX
2401 (similar to those existing for EVP_CIPHER_CTX).
2406 EVP_MD_CTX_init(&md); /* new function call */
2407 EVP_DigestInit(&md, EVP_sha1());
2408 EVP_DigestUpdate(&md, in, len);
2409 EVP_DigestFinal(&md, out, NULL);
2410 EVP_MD_CTX_cleanup(&md); /* new function call */
2414 *) Make DES key schedule conform to the usual scheme, as well as
2415 correcting its structure. This means that calls to DES functions
2416 now have to pass a pointer to a des_key_schedule instead of a
2417 plain des_key_schedule (which was actually always a pointer
2420 des_key_schedule ks;
2422 des_set_key_checked(..., &ks);
2423 des_ncbc_encrypt(..., &ks, ...);
2425 (Note that a later change renames 'des_...' into 'DES_...'.)
2428 *) Initial reduction of linker bloat: the use of some functions, such as
2429 PEM causes large amounts of unused functions to be linked in due to
2430 poor organisation. For example pem_all.c contains every PEM function
2431 which has a knock on effect of linking in large amounts of (unused)
2432 ASN1 code. Grouping together similar functions and splitting unrelated
2433 functions prevents this.
2436 *) Cleanup of EVP macros.
2439 *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
2440 correct _ecb suffix.
2443 *) Add initial OCSP responder support to ocsp application. The
2444 revocation information is handled using the text based index
2445 use by the ca application. The responder can either handle
2446 requests generated internally, supplied in files (for example
2447 via a CGI script) or using an internal minimal server.
2450 *) Add configuration choices to get zlib compression for TLS.
2453 *) Changes to Kerberos SSL for RFC 2712 compliance:
2454 1. Implemented real KerberosWrapper, instead of just using
2455 KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
2456 2. Implemented optional authenticator field of KerberosWrapper.
2458 Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
2459 and authenticator structs; see crypto/krb5/.
2461 Generalized Kerberos calls to support multiple Kerberos libraries.
2462 [Vern Staats <staatsvr@asc.hpc.mil>,
2463 Jeffrey Altman <jaltman@columbia.edu>
2464 via Richard Levitte]
2466 *) Cause 'openssl speed' to use fully hard-coded DSA keys as it
2467 already does with RSA. testdsa.h now has 'priv_key/pub_key'
2468 values for each of the key sizes rather than having just
2469 parameters (and 'speed' generating keys each time).
2472 *) Speed up EVP routines.
2475 type 8 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes

2490 *) Added the OS2-EMX target.
2491 ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
2493 *) Rewrite apps to use NCONF routines instead of the old CONF. New functions
2494 to support NCONF routines in extension code. New function CONF_set_nconf()
2495 to allow functions which take an NCONF to also handle the old LHASH
2496 structure: this means that the old CONF compatible routines can be
2497 retained (in particular wrt extensions) without having to duplicate the
2498 code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
2501 *) Enhance the general user interface with mechanisms for inner control
2502 and with possibilities to have yes/no kind of prompts.
2505 *) Change all calls to low level digest routines in the library and
2506 applications to use EVP. Add missing calls to HMAC_cleanup() and
2507 don't assume HMAC_CTX can be copied using memcpy().
2508 [Verdon Walker <VWalker@novell.com>, Steve Henson]
2510 *) Add the possibility to control engines through control names but with
2511 arbitrary arguments instead of just a string.
2512 Change the key loaders to take a UI_METHOD instead of a callback
2513 function pointer. NOTE: this breaks binary compatibility with earlier
2514 versions of OpenSSL [engine].
2515 Adapt the nCipher code for these new conditions and add a card insertion
2519 *) Enhance the general user interface with mechanisms to better support
2520 dialog box interfaces, application-defined prompts, the possibility
2521 to use defaults (for example default passwords from somewhere else)
2522 and interrupts/cancellations.
2525 *) Tidy up PKCS#12 attribute handling. Add support for the CSP name
2526 attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
2529 *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
2530 tidy up some unnecessarily weird code in 'sk_new()').
2531 [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
2533 *) Change the key loading routines for ENGINEs to use the same kind
2534 callback (pem_password_cb) as all other routines that need this
2538 *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
2539 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
2540 than this minimum value is recommended.
2543 *) New random seeder for OpenVMS, using the system process statistics
2544 that are easily reachable.
2547 *) Windows apparently can't transparently handle global
2548 variables defined in DLLs. Initialisations such as:
2550 const ASN1_ITEM *it = &ASN1_INTEGER_it;
2552 wont compile. This is used by the any applications that need to
2553 declare their own ASN1 modules. This was fixed by adding the option
2554 EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
2555 needed for static libraries under Win32.
2558 *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
2559 setting of purpose and trust fields. New X509_STORE trust and
2560 purpose functions and tidy up setting in other SSL functions.
2563 *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
2564 structure. These are inherited by X509_STORE_CTX when it is
2565 initialised. This allows various defaults to be set in the
2566 X509_STORE structure (such as flags for CRL checking and custom
2567 purpose or trust settings) for functions which only use X509_STORE_CTX
2568 internally such as S/MIME.
2570 Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
2571 trust settings if they are not set in X509_STORE. This allows X509_STORE
2572 purposes and trust (in S/MIME for example) to override any set by default.
2574 Add command line options for CRL checking to smime, s_client and s_server
2578 *) Initial CRL based revocation checking. If the CRL checking flag(s)
2579 are set then the CRL is looked up in the X509_STORE structure and
2580 its validity and signature checked, then if the certificate is found
2581 in the CRL the verify fails with a revoked error.
2583 Various new CRL related callbacks added to X509_STORE_CTX structure.
2585 Command line options added to 'verify' application to support this.
2587 This needs some additional work, such as being able to handle multiple
2588 CRLs with different times, extension based lookup (rather than just
2589 by subject name) and ultimately more complete V2 CRL extension
2593 *) Add a general user interface API (crypto/ui/). This is designed
2594 to replace things like des_read_password and friends (backward
2595 compatibility functions using this new API are provided).
2596 The purpose is to remove prompting functions from the DES code
2597 section as well as provide for prompting through dialog boxes in
2598 a window system and the like.
2601 *) Add "ex_data" support to ENGINE so implementations can add state at a
2602 per-structure level rather than having to store it globally.
2605 *) Make it possible for ENGINE structures to be copied when retrieved by
2606 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
2607 This causes the "original" ENGINE structure to act like a template,
2608 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
2609 operational state can be localised to each ENGINE structure, despite the
2610 fact they all share the same "methods". New ENGINE structures returned in
2611 this case have no functional references and the return value is the single
2612 structural reference. This matches the single structural reference returned
2613 by ENGINE_by_id() normally, when it is incremented on the pre-existing
2617 *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
2618 needs to match any other type at all we need to manually clear the
2622 *) Changes to the "openssl engine" utility to include;
2623 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
2624 about an ENGINE's available control commands.
2625 - executing control commands from command line arguments using the
2626 '-pre' and '-post' switches. '-post' is only used if '-t' is
2627 specified and the ENGINE is successfully initialised. The syntax for
2628 the individual commands are colon-separated, for example;
2629 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
2632 *) New dynamic control command support for ENGINEs. ENGINEs can now
2633 declare their own commands (numbers), names (strings), descriptions,
2634 and input types for run-time discovery by calling applications. A
2635 subset of these commands are implicitly classed as "executable"
2636 depending on their input type, and only these can be invoked through
2637 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
2638 can be based on user input, config files, etc). The distinction is
2639 that "executable" commands cannot return anything other than a boolean
2640 result and can only support numeric or string input, whereas some
2641 discoverable commands may only be for direct use through
2642 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
2643 pointers, or other custom uses. The "executable" commands are to
2644 support parameterisations of ENGINE behaviour that can be
2645 unambiguously defined by ENGINEs and used consistently across any
2646 OpenSSL-based application. Commands have been added to all the
2647 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
2648 control over shared-library paths without source code alterations.
2651 *) Changed all ENGINE implementations to dynamically allocate their
2652 ENGINEs rather than declaring them statically. Apart from this being
2653 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
2654 this also allows the implementations to compile without using the
2655 internal engine_int.h header.
2658 *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
2659 'const' value. Any code that should be able to modify a RAND_METHOD
2660 should already have non-const pointers to it (ie. they should only
2661 modify their own ones).
2664 *) Made a variety of little tweaks to the ENGINE code.
2665 - "atalla" and "ubsec" string definitions were moved from header files
2666 to C code. "nuron" string definitions were placed in variables
2667 rather than hard-coded - allowing parameterisation of these values
2668 later on via ctrl() commands.
2669 - Removed unused "#if 0"'d code.
2670 - Fixed engine list iteration code so it uses ENGINE_free() to release
2671 structural references.
2672 - Constified the RAND_METHOD element of ENGINE structures.
2673 - Constified various get/set functions as appropriate and added
2674 missing functions (including a catch-all ENGINE_cpy that duplicates
2675 all ENGINE values onto a new ENGINE except reference counts/state).
2676 - Removed NULL parameter checks in get/set functions. Setting a method
2677 or function to NULL is a way of cancelling out a previously set
2678 value. Passing a NULL ENGINE parameter is just plain stupid anyway
2679 and doesn't justify the extra error symbols and code.
2680 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
2681 flags from engine_int.h to engine.h.
2682 - Changed prototypes for ENGINE handler functions (init(), finish(),
2683 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
2686 *) Implement binary inversion algorithm for BN_mod_inverse in addition
2687 to the algorithm using long division. The binary algorithm can be
2688 used only if the modulus is odd. On 32-bit systems, it is faster
2689 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
2690 roughly 5-15% for 256-bit moduli), so we use it only for moduli
2691 up to 450 bits. In 64-bit environments, the binary algorithm
2692 appears to be advantageous for much longer moduli; here we use it
2693 for moduli up to 2048 bits.
2696 *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
2697 could not support the combine flag in choice fields.
2700 *) Add a 'copy_extensions' option to the 'ca' utility. This copies
2701 extensions from a certificate request to the certificate.
2704 *) Allow multiple 'certopt' and 'nameopt' options to be separated
2705 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
2706 file: this allows the display of the certificate about to be
2707 signed to be customised, to allow certain fields to be included
2708 or excluded and extension details. The old system didn't display
2709 multicharacter strings properly, omitted fields not in the policy
2710 and couldn't display additional details such as extensions.
2713 *) Function EC_POINTs_mul for multiple scalar multiplication
2714 of an arbitrary number of elliptic curve points
2715 \sum scalars[i]*points[i],
2716 optionally including the generator defined for the EC_GROUP:
2717 scalar*generator + \sum scalars[i]*points[i].
2719 EC_POINT_mul is a simple wrapper function for the typical case
2720 that the point list has just one item (besides the optional
2724 *) First EC_METHODs for curves over GF(p):
2726 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
2727 operations and provides various method functions that can also
2728 operate with faster implementations of modular arithmetic.
2730 EC_GFp_mont_method() reuses most functions that are part of
2731 EC_GFp_simple_method, but uses Montgomery arithmetic.
2733 [Bodo Moeller; point addition and point doubling
2734 implementation directly derived from source code provided by
2735 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
2737 *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
2738 crypto/ec/ec_lib.c):
2740 Curves are EC_GROUP objects (with an optional group generator)
2741 based on EC_METHODs that are built into the library.
2743 Points are EC_POINT objects based on EC_GROUP objects.
2745 Most of the framework would be able to handle curves over arbitrary
2746 finite fields, but as there are no obvious types for fields other
2747 than GF(p), some functions are limited to that for now.
2750 *) Add the -HTTP option to s_server. It is similar to -WWW, but requires
2751 that the file contains a complete HTTP response.
2754 *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
2755 change the def and num file printf format specifier from "%-40sXXX"
2756 to "%-39s XXX". The latter will always guarantee a space after the
2757 field while the former will cause them to run together if the field
2758 is 40 of more characters long.
2761 *) Constify the cipher and digest 'method' functions and structures
2762 and modify related functions to take constant EVP_MD and EVP_CIPHER
2766 *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
2767 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
2770 *) Modify EVP_Digest*() routines so they now return values. Although the
2771 internal software routines can never fail additional hardware versions
2775 *) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
2777 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
2778 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
2781 ERR_R_NESTED_ASN1_ERROR
2783 ERR_R_MISSING_ASN1_EOS
2784 were 4 .. 9, conflicting with
2785 ERR_LIB_RSA (= ERR_R_RSA_LIB)
2787 ERR_LIB_PEM (= ERR_R_PEM_LIB).
2788 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
2790 Add new error code 'ERR_R_INTERNAL_ERROR'.
2793 *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
2797 *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
2798 sets the subject name for a new request or supersedes the
2799 subject name in a given request. Formats that can be parsed are
2800 'CN=Some Name, OU=myOU, C=IT'
2802 'CN=Some Name/OU=myOU/C=IT'.
2804 Add options '-batch' and '-verbose' to 'openssl req'.
2805 [Massimiliano Pala <madwolf@hackmasters.net>]
2807 *) Introduce the possibility to access global variables through
2808 functions on platform were that's the best way to handle exporting
2809 global variables in shared libraries. To enable this functionality,
2810 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
2811 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
2812 is normally done by Configure or something similar).
2814 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
2815 in the source file (foo.c) like this:
2817 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
2818 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
2820 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
2821 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
2823 OPENSSL_DECLARE_GLOBAL(int,foo);
2824 #define foo OPENSSL_GLOBAL_REF(foo)
2825 OPENSSL_DECLARE_GLOBAL(double,bar);
2826 #define bar OPENSSL_GLOBAL_REF(bar)
2828 The #defines are very important, and therefore so is including the
2829 header file everywhere where the defined globals are used.
2831 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
2832 of ASN.1 items, but that structure is a bit different.
2834 The largest change is in util/mkdef.pl which has been enhanced with
2835 better and easier to understand logic to choose which symbols should
2836 go into the Windows .def files as well as a number of fixes and code
2837 cleanup (among others, algorithm keywords are now sorted
2838 lexicographically to avoid constant rewrites).
2841 *) In BN_div() keep a copy of the sign of 'num' before writing the
2842 result to 'rm' because if rm==num the value will be overwritten
2843 and produce the wrong result if 'num' is negative: this caused
2844 problems with BN_mod() and BN_nnmod().
2847 *) Function OCSP_request_verify(). This checks the signature on an
2848 OCSP request and verifies the signer certificate. The signer
2849 certificate is just checked for a generic purpose and OCSP request
2853 *) Add OCSP_check_validity() function to check the validity of OCSP
2854 responses. OCSP responses are prepared in real time and may only
2855 be a few seconds old. Simply checking that the current time lies
2856 between thisUpdate and nextUpdate max reject otherwise valid responses
2857 caused by either OCSP responder or client clock inaccuracy. Instead
2858 we allow thisUpdate and nextUpdate to fall within a certain period of
2859 the current time. The age of the response can also optionally be
2860 checked. Two new options -validity_period and -status_age added to
2864 *) If signature or public key algorithm is unrecognized print out its
2865 OID rather that just UNKNOWN.
2868 *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
2869 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
2870 ID to be generated from the issuer certificate alone which can then be
2871 passed to OCSP_id_issuer_cmp().
2874 *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
2875 ASN1 modules to export functions returning ASN1_ITEM pointers
2876 instead of the ASN1_ITEM structures themselves. This adds several
2877 new macros which allow the underlying ASN1 function/structure to
2878 be accessed transparently. As a result code should not use ASN1_ITEM
2879 references directly (such as &X509_it) but instead use the relevant
2880 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
2881 use of the new ASN1 code on platforms where exporting structures
2882 is problematical (for example in shared libraries) but exporting
2883 functions returning pointers to structures is not.
2886 *) Add support for overriding the generation of SSL/TLS session IDs.
2887 These callbacks can be registered either in an SSL_CTX or per SSL.
2888 The purpose of this is to allow applications to control, if they wish,
2889 the arbitrary values chosen for use as session IDs, particularly as it
2890 can be useful for session caching in multiple-server environments. A
2891 command-line switch for testing this (and any client code that wishes
2892 to use such a feature) has been added to "s_server".
2893 [Geoff Thorpe, Lutz Jaenicke]
2895 *) Modify mkdef.pl to recognise and parse preprocessor conditionals
2896 of the form '#if defined(...) || defined(...) || ...' and
2897 '#if !defined(...) && !defined(...) && ...'. This also avoids
2898 the growing number of special cases it was previously handling.
2901 *) Make all configuration macros available for application by making
2902 sure they are available in opensslconf.h, by giving them names starting
2903 with "OPENSSL_" to avoid conflicts with other packages and by making
2904 sure e_os2.h will cover all platform-specific cases together with
2906 Additionally, it is now possible to define configuration/platform-
2907 specific names (called "system identities"). In the C code, these
2908 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
2909 macro with the name beginning with "OPENSSL_SYS_", which is determined
2910 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
2914 *) New option -set_serial to 'req' and 'x509' this allows the serial
2915 number to use to be specified on the command line. Previously self
2916 signed certificates were hard coded with serial number 0 and the
2917 CA options of 'x509' had to use a serial number in a file which was
2921 *) New options to 'ca' utility to support V2 CRL entry extensions.
2922 Currently CRL reason, invalidity date and hold instruction are
2923 supported. Add new CRL extensions to V3 code and some new objects.
2926 *) New function EVP_CIPHER_CTX_set_padding() this is used to
2927 disable standard block padding (aka PKCS#5 padding) in the EVP
2928 API, which was previously mandatory. This means that the data is
2929 not padded in any way and so the total length much be a multiple
2930 of the block size, otherwise an error occurs.
2933 *) Initial (incomplete) OCSP SSL support.
2936 *) New function OCSP_parse_url(). This splits up a URL into its host,
2937 port and path components: primarily to parse OCSP URLs. New -url
2938 option to ocsp utility.
2941 *) New nonce behavior. The return value of OCSP_check_nonce() now
2942 reflects the various checks performed. Applications can decide
2943 whether to tolerate certain situations such as an absent nonce
2944 in a response when one was present in a request: the ocsp application
2945 just prints out a warning. New function OCSP_add1_basic_nonce()
2946 this is to allow responders to include a nonce in a response even if
2947 the request is nonce-less.
2950 *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
2951 skipped when using openssl x509 multiple times on a single input file,
2952 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
2955 *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
2956 set string type: to handle setting ASN1_TIME structures. Fix ca
2957 utility to correctly initialize revocation date of CRLs.
2960 *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
2961 the clients preferred ciphersuites and rather use its own preferences.
2962 Should help to work around M$ SGC (Server Gated Cryptography) bug in
2963 Internet Explorer by ensuring unchanged hash method during stepup.
2964 (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
2967 *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
2968 to aes and add a new 'exist' option to print out symbols that don't
2972 *) Additional options to ocsp utility to allow flags to be set and
2973 additional certificates supplied.
2976 *) Add the option -VAfile to 'openssl ocsp', so the user can give the
2977 OCSP client a number of certificate to only verify the response
2981 *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
2982 handle the new API. Currently only ECB, CBC modes supported. Add new
2985 Add TLS AES ciphersuites as described in RFC3268, "Advanced
2986 Encryption Standard (AES) Ciphersuites for Transport Layer
2987 Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were
2988 not enabled by default and were not part of the "ALL" ciphersuite
2989 alias because they were not yet official; they could be
2990 explicitly requested by specifying the "AESdraft" ciphersuite
2991 group alias. In the final release of OpenSSL 0.9.7, the group
2992 alias is called "AES" and is part of "ALL".)
2993 [Ben Laurie, Steve Henson, Bodo Moeller]
2995 *) New function OCSP_copy_nonce() to copy nonce value (if present) from
2996 request to response.
2999 *) Functions for OCSP responders. OCSP_request_onereq_count(),
3000 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
3001 extract information from a certificate request. OCSP_response_create()
3002 creates a response and optionally adds a basic response structure.
3003 OCSP_basic_add1_status() adds a complete single response to a basic
3004 response and returns the OCSP_SINGLERESP structure just added (to allow
3005 extensions to be included for example). OCSP_basic_add1_cert() adds a
3006 certificate to a basic response and OCSP_basic_sign() signs a basic
3007 response with various flags. New helper functions ASN1_TIME_check()
3008 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
3009 (converts ASN1_TIME to GeneralizedTime).
3012 *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
3013 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
3014 structure from a certificate. X509_pubkey_digest() digests the public_key
3015 contents: this is used in various key identifiers.
3018 *) Make sk_sort() tolerate a NULL argument.
3019 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
3021 *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
3022 passed by the function are trusted implicitly. If any of them signed the
3023 response then it is assumed to be valid and is not verified.
3026 *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
3027 to data. This was previously part of the PKCS7 ASN1 code. This
3028 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
3029 [Steve Henson, reported by Kenneth R. Robinette
3030 <support@securenetterm.com>]
3032 *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
3033 routines: without these tracing memory leaks is very painful.
3034 Fix leaks in PKCS12 and PKCS7 routines.
3037 *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
3038 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
3039 effectively meant GeneralizedTime would never be used. Now it
3040 is initialised to -1 but X509_time_adj() now has to check the value
3041 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
3042 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
3043 [Steve Henson, reported by Kenneth R. Robinette
3044 <support@securenetterm.com>]
3046 *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
3047 result in a zero length in the ASN1_INTEGER structure which was
3048 not consistent with the structure when d2i_ASN1_INTEGER() was used
3049 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
3050 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
3051 where it did not print out a minus for negative ASN1_INTEGER.
3054 *) Add summary printout to ocsp utility. The various functions which
3055 convert status values to strings have been renamed to:
3056 OCSP_response_status_str(), OCSP_cert_status_str() and
3057 OCSP_crl_reason_str() and are no longer static. New options
3058 to verify nonce values and to disable verification. OCSP response
3059 printout format cleaned up.
3062 *) Add additional OCSP certificate checks. These are those specified
3063 in RFC2560. This consists of two separate checks: the CA of the
3064 certificate being checked must either be the OCSP signer certificate
3065 or the issuer of the OCSP signer certificate. In the latter case the
3066 OCSP signer certificate must contain the OCSP signing extended key
3067 usage. This check is performed by attempting to match the OCSP
3068 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
3069 in the OCSP_CERTID structures of the response.
3072 *) Initial OCSP certificate verification added to OCSP_basic_verify()
3073 and related routines. This uses the standard OpenSSL certificate
3074 verify routines to perform initial checks (just CA validity) and
3075 to obtain the certificate chain. Then additional checks will be
3076 performed on the chain. Currently the root CA is checked to see
3077 if it is explicitly trusted for OCSP signing. This is used to set
3078 a root CA as a global signing root: that is any certificate that
3079 chains to that CA is an acceptable OCSP signing certificate.
3082 *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
3083 extensions from a separate configuration file.
3084 As when reading extensions from the main configuration file,
3085 the '-extensions ...' option may be used for specifying the
3087 [Massimiliano Pala <madwolf@comune.modena.it>]
3089 *) New OCSP utility. Allows OCSP requests to be generated or
3090 read. The request can be sent to a responder and the output
3091 parsed, outputed or printed in text form. Not complete yet:
3092 still needs to check the OCSP response validity.
3095 *) New subcommands for 'openssl ca':
3096 'openssl ca -status <serial>' prints the status of the cert with
3097 the given serial number (according to the index file).
3098 'openssl ca -updatedb' updates the expiry status of certificates
3100 [Massimiliano Pala <madwolf@comune.modena.it>]
3102 *) New '-newreq-nodes' command option to CA.pl. This is like
3103 '-newreq', but calls 'openssl req' with the '-nodes' option
3104 so that the resulting key is not encrypted.
3105 [Damien Miller <djm@mindrot.org>]
3107 *) New configuration for the GNU Hurd.
3108 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
3110 *) Initial code to implement OCSP basic response verify. This
3111 is currently incomplete. Currently just finds the signer's
3112 certificate and verifies the signature on the response.
3115 *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
3116 value of OPENSSLDIR. This is available via the new '-d' option
3117 to 'openssl version', and is also included in 'openssl version -a'.
3120 *) Allowing defining memory allocation callbacks that will be given
3121 file name and line number information in additional arguments
3122 (a const char* and an int). The basic functionality remains, as
3123 well as the original possibility to just replace malloc(),
3124 realloc() and free() by functions that do not know about these
3125 additional arguments. To register and find out the current
3126 settings for extended allocation functions, the following
3127 functions are provided:
3129 CRYPTO_set_mem_ex_functions
3130 CRYPTO_set_locked_mem_ex_functions
3131 CRYPTO_get_mem_ex_functions
3132 CRYPTO_get_locked_mem_ex_functions
3134 These work the same way as CRYPTO_set_mem_functions and friends.
3135 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
3136 extended allocation function is enabled.
3137 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
3138 a conventional allocation function is enabled.
3139 [Richard Levitte, Bodo Moeller]
3141 *) Finish off removing the remaining LHASH function pointer casts.
3142 There should no longer be any prototype-casting required when using
3143 the LHASH abstraction, and any casts that remain are "bugs". See
3144 the callback types and macros at the head of lhash.h for details
3145 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
3148 *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
3149 If /dev/[u]random devices are not available or do not return enough
3150 entropy, EGD style sockets (served by EGD or PRNGD) will automatically
3152 The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
3153 /etc/entropy will be queried once each in this sequence, quering stops
3154 when enough entropy was collected without querying more sockets.
3157 *) Change the Unix RAND_poll() variant to be able to poll several
3158 random devices, as specified by DEVRANDOM, until a sufficient amount
3159 of data has been collected. We spend at most 10 ms on each file
3160 (select timeout) and read in non-blocking mode. DEVRANDOM now
3161 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
3162 (previously it was just the string "/dev/urandom"), so on typical
3163 platforms the 10 ms delay will never occur.
3164 Also separate out the Unix variant to its own file, rand_unix.c.
3165 For VMS, there's a currently-empty rand_vms.c.
3168 *) Move OCSP client related routines to ocsp_cl.c. These
3169 provide utility functions which an application needing
3170 to issue a request to an OCSP responder and analyse the
3171 response will typically need: as opposed to those which an
3172 OCSP responder itself would need which will be added later.
3174 OCSP_request_sign() signs an OCSP request with an API similar
3175 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
3176 response. OCSP_response_get1_basic() extracts basic response
3177 from response. OCSP_resp_find_status(): finds and extracts status
3178 information from an OCSP_CERTID structure (which will be created
3179 when the request structure is built). These are built from lower
3180 level functions which work on OCSP_SINGLERESP structures but
3181 wont normally be used unless the application wishes to examine
3182 extensions in the OCSP response for example.
3184 Replace nonce routines with a pair of functions.
3185 OCSP_request_add1_nonce() adds a nonce value and optionally
3186 generates a random value. OCSP_check_nonce() checks the
3187 validity of the nonce in an OCSP response.
3190 *) Change function OCSP_request_add() to OCSP_request_add0_id().
3191 This doesn't copy the supplied OCSP_CERTID and avoids the
3192 need to free up the newly created id. Change return type
3193 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
3194 This can then be used to add extensions to the request.
3195 Deleted OCSP_request_new(), since most of its functionality
3196 is now in OCSP_REQUEST_new() (and the case insensitive name
3197 clash) apart from the ability to set the request name which
3198 will be added elsewhere.
3201 *) Update OCSP API. Remove obsolete extensions argument from
3202 various functions. Extensions are now handled using the new
3203 OCSP extension code. New simple OCSP HTTP function which
3204 can be used to send requests and parse the response.
3207 *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
3208 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
3209 uses the special reorder version of SET OF to sort the attributes
3210 and reorder them to match the encoded order. This resolves a long
3211 standing problem: a verify on a PKCS7 structure just after signing
3212 it used to fail because the attribute order did not match the
3213 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
3214 it uses the received order. This is necessary to tolerate some broken
3215 software that does not order SET OF. This is handled by encoding
3216 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
3217 to produce the required SET OF.
3220 *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
3221 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
3222 files to get correct declarations of the ASN.1 item variables.
3225 *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
3226 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
3227 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
3228 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
3229 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
3230 ASN1_ITEM and no wrapper functions.
3233 *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
3234 replace the old function pointer based I/O routines. Change most of
3235 the *_d2i_bio() and *_d2i_fp() functions to use these.
3238 *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
3239 lines, recognice more "algorithms" that can be deselected, and make
3240 it complain about algorithm deselection that isn't recognised.
3243 *) New ASN1 functions to handle dup, sign, verify, digest, pack and
3244 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
3245 to use new functions. Add NO_ASN1_OLD which can be set to remove
3246 some old style ASN1 functions: this can be used to determine if old
3247 code will still work when these eventually go away.
3250 *) New extension functions for OCSP structures, these follow the
3251 same conventions as certificates and CRLs.
3254 *) New function X509V3_add1_i2d(). This automatically encodes and
3255 adds an extension. Its behaviour can be customised with various
3256 flags to append, replace or delete. Various wrappers added for
3257 certifcates and CRLs.
3260 *) Fix to avoid calling the underlying ASN1 print routine when
3261 an extension cannot be parsed. Correct a typo in the
3262 OCSP_SERVICELOC extension. Tidy up print OCSP format.
3265 *) Make mkdef.pl parse some of the ASN1 macros and add apropriate
3266 entries for variables.
3269 *) Add functionality to apps/openssl.c for detecting locking
3270 problems: As the program is single-threaded, all we have
3271 to do is register a locking callback using an array for
3272 storing which locks are currently held by the program.
3275 *) Use a lock around the call to CRYPTO_get_ex_new_index() in
3276 SSL_get_ex_data_X509_STORE_idx(), which is used in
3277 ssl_verify_cert_chain() and thus can be called at any time
3278 during TLS/SSL handshakes so that thread-safety is essential.
3279 Unfortunately, the ex_data design is not at all suited
3280 for multi-threaded use, so it probably should be abolished.
3283 *) Added Broadcom "ubsec" ENGINE to OpenSSL.
3284 [Broadcom, tweaked and integrated by Geoff Thorpe]
3286 *) Move common extension printing code to new function
3287 X509V3_print_extensions(). Reorganise OCSP print routines and
3288 implement some needed OCSP ASN1 functions. Add OCSP extensions.
3291 *) New function X509_signature_print() to remove duplication in some
3295 *) Add a special meaning when SET OF and SEQUENCE OF flags are both
3296 set (this was treated exactly the same as SET OF previously). This
3297 is used to reorder the STACK representing the structure to match the
3298 encoding. This will be used to get round a problem where a PKCS7
3299 structure which was signed could not be verified because the STACK
3300 order did not reflect the encoded order.
3303 *) Reimplement the OCSP ASN1 module using the new code.
3306 *) Update the X509V3 code to permit the use of an ASN1_ITEM structure
3307 for its ASN1 operations. The old style function pointers still exist
3308 for now but they will eventually go away.
3311 *) Merge in replacement ASN1 code from the ASN1 branch. This almost
3312 completely replaces the old ASN1 functionality with a table driven
3313 encoder and decoder which interprets an ASN1_ITEM structure describing
3314 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
3315 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
3316 has also been converted to the new form.
3319 *) Change BN_mod_exp_recp so that negative moduli are tolerated
3320 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
3321 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
3322 for negative moduli.
3325 *) Fix BN_uadd and BN_usub: Always return non-negative results instead
3326 of not touching the result's sign bit.
3329 *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
3333 *) Changed the LHASH code to use prototypes for callbacks, and created
3334 macros to declare and implement thin (optionally static) functions
3335 that provide type-safety and avoid function pointer casting for the
3336 type-specific callbacks.
3339 *) Added Kerberos Cipher Suites to be used with TLS, as written in
3341 [Veers Staats <staatsvr@asc.hpc.mil>,
3342 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
3344 *) Reformat the FAQ so the different questions and answers can be divided
3345 in sections depending on the subject.
3348 *) Have the zlib compression code load ZLIB.DLL dynamically under
3352 *) New function BN_mod_sqrt for computing square roots modulo a prime
3353 (using the probabilistic Tonelli-Shanks algorithm unless
3354 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
3355 be handled deterministically).
3356 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
3358 *) Make BN_mod_inverse faster by explicitly handling small quotients
3359 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
3360 512 bits], about 30% for larger ones [1024 or 2048 bits].)
3363 *) New function BN_kronecker.
3366 *) Fix BN_gcd so that it works on negative inputs; the result is
3367 positive unless both parameters are zero.
3368 Previously something reasonably close to an infinite loop was
3369 possible because numbers could be growing instead of shrinking
3370 in the implementation of Euclid's algorithm.
3373 *) Fix BN_is_word() and BN_is_one() macros to take into account the
3374 sign of the number in question.
3376 Fix BN_is_word(a,w) to work correctly for w == 0.
3378 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
3379 because its test if the absolute value of 'a' equals 'w'.
3380 Note that BN_abs_is_word does *not* handle w == 0 reliably;
3381 it exists mostly for use in the implementations of BN_is_zero(),
3382 BN_is_one(), and BN_is_word().
3385 *) New function BN_swap.
3388 *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
3389 the exponentiation functions are more likely to produce reasonable
3390 results on negative inputs.
3393 *) Change BN_mod_mul so that the result is always non-negative.
3394 Previously, it could be negative if one of the factors was negative;
3395 I don't think anyone really wanted that behaviour.
3398 *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
3399 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
3400 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
3401 and add new functions:
3410 BN_mod_lshift1_quick
3414 These functions always generate non-negative results.
3416 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
3417 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
3419 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
3420 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
3421 be reduced modulo m.
3422 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
3425 The following entry accidentily appeared in the CHANGES file
3426 distributed with OpenSSL 0.9.7. The modifications described in
3427 it do *not* apply to OpenSSL 0.9.7.
3429 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
3430 was actually never needed) and in BN_mul(). The removal in BN_mul()
3431 required a small change in bn_mul_part_recursive() and the addition
3432 of the functions bn_cmp_part_words(), bn_sub_part_words() and
3433 bn_add_part_words(), which do the same thing as bn_cmp_words(),
3434 bn_sub_words() and bn_add_words() except they take arrays with
3439 *) In 'openssl passwd', verify passwords read from the terminal
3440 unless the '-salt' option is used (which usually means that
3441 verification would just waste user's time since the resulting
3442 hash is going to be compared with some given password hash)
3443 or the new '-noverify' option is used.
3445 This is an incompatible change, but it does not affect
3446 non-interactive use of 'openssl passwd' (passwords on the command
3447 line, '-stdin' option, '-in ...' option) and thus should not
3451 *) Remove all references to RSAref, since there's no more need for it.
3454 *) Make DSO load along a path given through an environment variable
3455 (SHLIB_PATH) with shl_load().
3458 *) Constify the ENGINE code as a result of BIGNUM constification.
3459 Also constify the RSA code and most things related to it. In a
3460 few places, most notable in the depth of the ASN.1 code, ugly
3461 casts back to non-const were required (to be solved at a later
3465 *) Make it so the openssl application has all engines loaded by default.
3468 *) Constify the BIGNUM routines a little more.
3471 *) Add the following functions:
3473 ENGINE_load_cswift()
3475 ENGINE_load_atalla()
3477 ENGINE_load_builtin_engines()
3479 That way, an application can itself choose if external engines that
3480 are built-in in OpenSSL shall ever be used or not. The benefit is
3481 that applications won't have to be linked with libdl or other dso
3482 libraries unless it's really needed.
3484 Changed 'openssl engine' to load all engines on demand.
3485 Changed the engine header files to avoid the duplication of some
3486 declarations (they differed!).
3489 *) 'openssl engine' can now list capabilities.
3492 *) Better error reporting in 'openssl engine'.
3495 *) Never call load_dh_param(NULL) in s_server.
3498 *) Add engine application. It can currently list engines by name and
3499 identity, and test if they are actually available.
3502 *) Improve RPM specification file by forcing symbolic linking and making
3503 sure the installed documentation is also owned by root.root.
3504 [Damien Miller <djm@mindrot.org>]
3506 *) Give the OpenSSL applications more possibilities to make use of
3507 keys (public as well as private) handled by engines.
3510 *) Add OCSP code that comes from CertCo.
3513 *) Add VMS support for the Rijndael code.
3516 *) Added untested support for Nuron crypto accelerator.
3519 *) Add support for external cryptographic devices. This code was
3520 previously distributed separately as the "engine" branch.
3521 [Geoff Thorpe, Richard Levitte]
3523 *) Rework the filename-translation in the DSO code. It is now possible to
3524 have far greater control over how a "name" is turned into a filename
3525 depending on the operating environment and any oddities about the
3526 different shared library filenames on each system.
3529 *) Support threads on FreeBSD-elf in Configure.
3532 *) Fix for SHA1 assembly problem with MASM: it produces
3533 warnings about corrupt line number information when assembling
3534 with debugging information. This is caused by the overlapping
3536 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
3539 NCONF_get_number() has no error checking at all. As a replacement,
3540 NCONF_get_number_e() is defined (_e for "error checking") and is
3541 promoted strongly. The old NCONF_get_number is kept around for
3542 binary backward compatibility.
3543 Make it possible for methods to load from something other than a BIO,
3544 by providing a function pointer that is given a name instead of a BIO.
3545 For example, this could be used to load configuration data from an
3549 *) Fix for non blocking accept BIOs. Added new I/O special reason
3550 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
3551 with non blocking I/O was not possible because no retry code was
3552 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
3556 *) Added the beginnings of Rijndael support.
3559 *) Fix for bug in DirectoryString mask setting. Add support for
3560 X509_NAME_print_ex() in 'req' and X509_print_ex() function
3561 to allow certificate printing to more controllable, additional
3562 'certopt' option to 'x509' to allow new printing options to be
3566 *) Clean old EAY MD5 hack from e_os.h.
3569 Changes between 0.9.6l and 0.9.6m [17 Mar 2004]
3571 *) Fix null-pointer assignment in do_change_cipher_spec() revealed
3572 by using the Codenomicon TLS Test Tool (CVE-2004-0079)
3573 [Joe Orton, Steve Henson]
3575 Changes between 0.9.6k and 0.9.6l [04 Nov 2003]
3577 *) Fix additional bug revealed by the NISCC test suite:
3579 Stop bug triggering large recursion when presented with
3580 certain ASN.1 tags (CVE-2003-0851)
3583 Changes between 0.9.6j and 0.9.6k [30 Sep 2003]
3585 *) Fix various bugs revealed by running the NISCC test suite:
3587 Stop out of bounds reads in the ASN1 code when presented with
3588 invalid tags (CVE-2003-0543 and CVE-2003-0544).
3590 If verify callback ignores invalid public key errors don't try to check
3591 certificate signature with the NULL public key.
3595 *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
3596 if the server requested one: as stated in TLS 1.0 and SSL 3.0
3600 *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
3601 extra data after the compression methods not only for TLS 1.0
3602 but also for SSL 3.0 (as required by the specification).
3603 [Bodo Moeller; problem pointed out by Matthias Loepfe]
3605 *) Change X509_certificate_type() to mark the key as exported/exportable
3606 when it's 512 *bits* long, not 512 bytes.
3609 Changes between 0.9.6i and 0.9.6j [10 Apr 2003]
3611 *) Countermeasure against the Klima-Pokorny-Rosa extension of
3612 Bleichbacher's attack on PKCS #1 v1.5 padding: treat
3613 a protocol version number mismatch like a decryption error
3614 in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
3617 *) Turn on RSA blinding by default in the default implementation
3618 to avoid a timing attack. Applications that don't want it can call
3619 RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
3620 They would be ill-advised to do so in most cases.
3621 [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
3623 *) Change RSA blinding code so that it works when the PRNG is not
3624 seeded (in this case, the secret RSA exponent is abused as
3625 an unpredictable seed -- if it is not unpredictable, there
3626 is no point in blinding anyway). Make RSA blinding thread-safe
3627 by remembering the creator's thread ID in rsa->blinding and
3628 having all other threads use local one-time blinding factors
3629 (this requires more computation than sharing rsa->blinding, but
3630 avoids excessive locking; and if an RSA object is not shared
3631 between threads, blinding will still be very fast).
3634 Changes between 0.9.6h and 0.9.6i [19 Feb 2003]
3636 *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
3637 via timing by performing a MAC computation even if incorrrect
3638 block cipher padding has been found. This is a countermeasure
3639 against active attacks where the attacker has to distinguish
3640 between bad padding and a MAC verification error. (CVE-2003-0078)
3642 [Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
3643 Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
3644 Martin Vuagnoux (EPFL, Ilion)]
3646 Changes between 0.9.6g and 0.9.6h [5 Dec 2002]
3648 *) New function OPENSSL_cleanse(), which is used to cleanse a section of
3649 memory from it's contents. This is done with a counter that will
3650 place alternating values in each byte. This can be used to solve
3651 two issues: 1) the removal of calls to memset() by highly optimizing
3652 compilers, and 2) cleansing with other values than 0, since those can
3653 be read through on certain media, for example a swap space on disk.
3656 *) Bugfix: client side session caching did not work with external caching,
3657 because the session->cipher setting was not restored when reloading
3658 from the external cache. This problem was masked, when
3659 SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set.
3660 (Found by Steve Haslam <steve@araqnid.ddts.net>.)
3663 *) Fix client_certificate (ssl/s2_clnt.c): The permissible total
3664 length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
3665 [Zeev Lieber <zeev-l@yahoo.com>]
3667 *) Undo an undocumented change introduced in 0.9.6e which caused
3668 repeated calls to OpenSSL_add_all_ciphers() and
3669 OpenSSL_add_all_digests() to be ignored, even after calling
3673 *) Change the default configuration reader to deal with last line not
3674 being properly terminated.
3677 *) Change X509_NAME_cmp() so it applies the special rules on handling
3678 DN values that are of type PrintableString, as well as RDNs of type
3679 emailAddress where the value has the type ia5String.
3680 [stefank@valicert.com via Richard Levitte]
3682 *) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half
3683 the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
3684 doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
3685 the bitwise-OR of the two for use by the majority of applications
3686 wanting this behaviour, and update the docs. The documented
3687 behaviour and actual behaviour were inconsistent and had been
3688 changing anyway, so this is more a bug-fix than a behavioural
3690 [Geoff Thorpe, diagnosed by Nadav Har'El]
3692 *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
3693 (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
3696 *) Fix initialization code race conditions in
3697 SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),
3698 SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(),
3699 SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(),
3700 TLSv1_method(), TLSv1_client_method(), TLSv1_server_method(),
3701 ssl2_get_cipher_by_char(),
3702 ssl3_get_cipher_by_char().
3703 [Patrick McCormick <patrick@tellme.com>, Bodo Moeller]
3705 *) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
3706 the cached sessions are flushed, as the remove_cb() might use ex_data
3707 contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com>
3708 (see [openssl.org #212]).
3709 [Geoff Thorpe, Lutz Jaenicke]
3711 *) Fix typo in OBJ_txt2obj which incorrectly passed the content
3712 length, instead of the encoding length to d2i_ASN1_OBJECT.
3715 Changes between 0.9.6f and 0.9.6g [9 Aug 2002]
3717 *) [In 0.9.6g-engine release:]
3718 Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall').
3719 [Lynn Gazis <lgazis@rainbow.com>]
3721 Changes between 0.9.6e and 0.9.6f [8 Aug 2002]
3723 *) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX
3724 and get fix the header length calculation.
3725 [Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>,
3726 Alon Kantor <alonk@checkpoint.com> (and others),
3729 *) Use proper error handling instead of 'assertions' in buffer
3730 overflow checks added in 0.9.6e. This prevents DoS (the
3731 assertions could call abort()).
3732 [Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]
3734 Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
3736 *) Add various sanity checks to asn1_get_length() to reject
3737 the ASN1 length bytes if they exceed sizeof(long), will appear
3738 negative or the content length exceeds the length of the
3740 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
3742 *) Fix cipher selection routines: ciphers without encryption had no flags
3743 for the cipher strength set and where therefore not handled correctly
3744 by the selection routines (PR #130).
3747 *) Fix EVP_dsa_sha macro.
3751 SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
3752 for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
3753 that was added in OpenSSL 0.9.6d.
3755 As the countermeasure turned out to be incompatible with some
3756 broken SSL implementations, the new option is part of SSL_OP_ALL.
3757 SSL_OP_ALL is usually employed when compatibility with weird SSL
3758 implementations is desired (e.g. '-bugs' option to 's_client' and
3759 's_server'), so the new option is automatically set in many
3763 *) Changes in security patch:
3765 Changes marked "(CHATS)" were sponsored by the Defense Advanced
3766 Research Projects Agency (DARPA) and Air Force Research Laboratory,
3767 Air Force Materiel Command, USAF, under agreement number
3770 *) Add various sanity checks to asn1_get_length() to reject
3771 the ASN1 length bytes if they exceed sizeof(long), will appear
3772 negative or the content length exceeds the length of the
3773 supplied buffer. (CVE-2002-0659)
3774 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
3776 *) Assertions for various potential buffer overflows, not known to
3778 [Ben Laurie (CHATS)]
3780 *) Various temporary buffers to hold ASCII versions of integers were
3781 too small for 64 bit platforms. (CVE-2002-0655)
3782 [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
3784 *) Remote buffer overflow in SSL3 protocol - an attacker could
3785 supply an oversized session ID to a client. (CVE-2002-0656)
3786 [Ben Laurie (CHATS)]
3788 *) Remote buffer overflow in SSL2 protocol - an attacker could
3789 supply an oversized client master key. (CVE-2002-0656)
3790 [Ben Laurie (CHATS)]
3792 Changes between 0.9.6c and 0.9.6d [9 May 2002]
3794 *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
3795 encoded as NULL) with id-dsa-with-sha1.
3796 [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
3798 *) Check various X509_...() return values in apps/req.c.
3799 [Nils Larsch <nla@trustcenter.de>]
3801 *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
3802 an end-of-file condition would erronously be flagged, when the CRLF
3803 was just at the end of a processed block. The bug was discovered when
3804 processing data through a buffering memory BIO handing the data to a
3805 BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
3806 <ptsekov@syntrex.com> and Nedelcho Stanev.
3809 *) Implement a countermeasure against a vulnerability recently found
3810 in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
3811 before application data chunks to avoid the use of known IVs
3812 with data potentially chosen by the attacker.
3815 *) Fix length checks in ssl3_get_client_hello().
3818 *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
3819 to prevent ssl3_read_internal() from incorrectly assuming that
3820 ssl3_read_bytes() found application data while handshake
3821 processing was enabled when in fact s->s3->in_read_app_data was
3822 merely automatically cleared during the initial handshake.
3823 [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
3825 *) Fix object definitions for Private and Enterprise: they were not
3826 recognized in their shortname (=lowercase) representation. Extend
3827 obj_dat.pl to issue an error when using undefined keywords instead
3828 of silently ignoring the problem (Svenning Sorensen
3829 <sss@sss.dnsalias.net>).
3832 *) Fix DH_generate_parameters() so that it works for 'non-standard'
3833 generators, i.e. generators other than 2 and 5. (Previously, the
3834 code did not properly initialise the 'add' and 'rem' values to
3835 BN_generate_prime().)
3837 In the new general case, we do not insist that 'generator' is
3838 actually a primitive root: This requirement is rather pointless;
3839 a generator of the order-q subgroup is just as good, if not
3843 *) Map new X509 verification errors to alerts. Discovered and submitted by
3844 Tom Wu <tom@arcot.com>.
3847 *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
3848 returning non-zero before the data has been completely received
3849 when using non-blocking I/O.
3850 [Bodo Moeller; problem pointed out by John Hughes]
3852 *) Some of the ciphers missed the strength entry (SSL_LOW etc).
3853 [Ben Laurie, Lutz Jaenicke]
3855 *) Fix bug in SSL_clear(): bad sessions were not removed (found by
3856 Yoram Zahavi <YoramZ@gilian.com>).
3859 *) Add information about CygWin 1.3 and on, and preserve proper
3860 configuration for the versions before that.
3861 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
3863 *) Make removal from session cache (SSL_CTX_remove_session()) more robust:
3864 check whether we deal with a copy of a session and do not delete from
3865 the cache in this case. Problem reported by "Izhar Shoshani Levi"
3866 <izhar@checkpoint.com>.
3869 *) Do not store session data into the internal session cache, if it
3870 is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
3871 flag is set). Proposed by Aslam <aslam@funk.com>.
3874 *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
3878 *) [In 0.9.6d-engine release:]
3879 Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
3880 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
3882 *) Add the configuration target linux-s390x.
3883 [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
3885 *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
3886 ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
3887 variable as an indication that a ClientHello message has been
3888 received. As the flag value will be lost between multiple
3889 invocations of ssl3_accept when using non-blocking I/O, the
3890 function may not be aware that a handshake has actually taken
3891 place, thus preventing a new session from being added to the
3894 To avoid this problem, we now set s->new_session to 2 instead of
3895 using a local variable.
3896 [Lutz Jaenicke, Bodo Moeller]
3898 *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
3899 if the SSL_R_LENGTH_MISMATCH error is detected.
3900 [Geoff Thorpe, Bodo Moeller]
3902 *) New 'shared_ldflag' column in Configure platform table.
3905 *) Fix EVP_CIPHER_mode macro.
3906 ["Dan S. Camper" <dan@bti.net>]
3908 *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
3909 type, we must throw them away by setting rr->length to 0.
3910 [D P Chang <dpc@qualys.com>]
3912 Changes between 0.9.6b and 0.9.6c [21 dec 2001]
3914 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
3915 <Dominikus.Scherkl@biodata.com>. (The previous implementation
3916 worked incorrectly for those cases where range = 10..._2 and
3917 3*range is two bits longer than range.)
3920 *) Only add signing time to PKCS7 structures if it is not already
3924 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
3925 OBJ_ld_ce should be OBJ_id_ce.
3926 Also some ip-pda OIDs in crypto/objects/objects.txt were
3927 incorrect (cf. RFC 3039).
3928 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
3930 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
3931 returns early because it has nothing to do.
3932 [Andy Schneider <andy.schneider@bjss.co.uk>]
3934 *) [In 0.9.6c-engine release:]
3935 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
3936 [Andy Schneider <andy.schneider@bjss.co.uk>]
3938 *) [In 0.9.6c-engine release:]
3939 Add support for Cryptographic Appliance's keyserver technology.
3940 (Use engine 'keyclient')
3941 [Cryptographic Appliances and Geoff Thorpe]
3943 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
3944 is called via tools/c89.sh because arguments have to be
3945 rearranged (all '-L' options must appear before the first object
3947 [Richard Shapiro <rshapiro@abinitio.com>]
3949 *) [In 0.9.6c-engine release:]
3950 Add support for Broadcom crypto accelerator cards, backported
3952 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
3954 *) [In 0.9.6c-engine release:]
3955 Add support for SureWare crypto accelerator cards from
3956 Baltimore Technologies. (Use engine 'sureware')
3957 [Baltimore Technologies and Mark Cox]
3959 *) [In 0.9.6c-engine release:]
3960 Add support for crypto accelerator cards from Accelerated
3961 Encryption Processing, www.aep.ie. (Use engine 'aep')
3962 [AEP Inc. and Mark Cox]
3964 *) Add a configuration entry for gcc on UnixWare.
3965 [Gary Benson <gbenson@redhat.com>]
3967 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
3968 messages are stored in a single piece (fixed-length part and
3969 variable-length part combined) and fix various bugs found on the way.
3972 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
3973 instead. BIO_gethostbyname() does not know what timeouts are
3974 appropriate, so entries would stay in cache even when they have
3976 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
3978 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
3979 faced with a pathologically small ClientHello fragment that does
3980 not contain client_version: Instead of aborting with an error,
3981 simply choose the highest available protocol version (i.e.,
3982 TLS 1.0 unless it is disabled). In practice, ClientHello
3983 messages are never sent like this, but this change gives us
3984 strictly correct behaviour at least for TLS.
3987 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
3988 never resets s->method to s->ctx->method when called from within
3989 one of the SSL handshake functions.
3990 [Bodo Moeller; problem pointed out by Niko Baric]
3992 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
3993 (sent using the client's version number) if client_version is
3994 smaller than the protocol version in use. Also change
3995 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
3996 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
3997 the client will at least see that alert.
4000 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
4004 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
4005 client receives HelloRequest while in a handshake.
4006 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
4008 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
4009 should end in 'break', not 'goto end' which circuments various
4010 cleanups done in state SSL_ST_OK. But session related stuff
4011 must be disabled for SSL_ST_OK in the case that we just sent a
4014 Also avoid some overhead by not calling ssl_init_wbio_buffer()
4015 before just sending a HelloRequest.
4016 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
4018 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
4019 reveal whether illegal block cipher padding was found or a MAC
4020 verification error occured. (Neither SSLerr() codes nor alerts
4021 are directly visible to potential attackers, but the information
4022 may leak via logfiles.)
4024 Similar changes are not required for the SSL 2.0 implementation
4025 because the number of padding bytes is sent in clear for SSL 2.0,
4026 and the extra bytes are just ignored. However ssl/s2_pkt.c
4027 failed to verify that the purported number of padding bytes is in
4031 *) Add OpenUNIX-8 support including shared libraries
4032 (Boyd Lynn Gerber <gerberb@zenez.com>).
4035 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
4036 'wristwatch attack' using huge encoding parameters (cf.
4037 James H. Manger's CRYPTO 2001 paper). Note that the
4038 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
4039 encoding parameters and hence was not vulnerable.
4042 *) BN_sqr() bug fix.
4043 [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
4045 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
4046 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
4047 followed by modular reduction.
4048 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
4050 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
4051 equivalent based on BN_pseudo_rand() instead of BN_rand().
4054 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
4055 This function was broken, as the check for a new client hello message
4056 to handle SGC did not allow these large messages.
4057 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
4060 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
4063 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
4064 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
4067 *) Rework the configuration and shared library support for Tru64 Unix.
4068 The configuration part makes use of modern compiler features and
4069 still retains old compiler behavior for those that run older versions
4070 of the OS. The shared library support part includes a variant that
4071 uses the RPATH feature, and is available through the special
4072 configuration target "alpha-cc-rpath", which will never be selected
4074 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
4076 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
4077 with the same message size as in ssl3_get_certificate_request().
4078 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
4079 messages might inadvertently be reject as too long.
4080 [Petr Lampa <lampa@fee.vutbr.cz>]
4082 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
4085 *) Modified SSL library such that the verify_callback that has been set
4086 specificly for an SSL object with SSL_set_verify() is actually being
4087 used. Before the change, a verify_callback set with this function was
4088 ignored and the verify_callback() set in the SSL_CTX at the time of
4089 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
4090 to allow the necessary settings.
4093 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
4094 explicitly to NULL, as at least on Solaris 8 this seems not always to be
4095 done automatically (in contradiction to the requirements of the C
4096 standard). This made problems when used from OpenSSH.
4099 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
4100 dh->length and always used
4102 BN_rand_range(priv_key, dh->p).
4104 BN_rand_range() is not necessary for Diffie-Hellman, and this
4105 specific range makes Diffie-Hellman unnecessarily inefficient if
4106 dh->length (recommended exponent length) is much smaller than the
4107 length of dh->p. We could use BN_rand_range() if the order of
4108 the subgroup was stored in the DH structure, but we only have
4113 BN_rand(priv_key, l, ...)
4115 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1

4127 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
4128 always reject numbers >= n.
4131 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
4132 to synchronize access to 'locking_thread'. This is necessary on
4133 systems where access to 'locking_thread' (an 'unsigned long'
4134 variable) is not atomic.
4137 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
4138 *before* setting the 'crypto_lock_rand' flag. The previous code had
4139 a race condition if 0 is a valid thread ID.
4140 [Travis Vitek <vitek@roguewave.com>]
4142 *) Add support for shared libraries under Irix.
4143 [Albert Chin-A-Young <china@thewrittenword.com>]
4145 *) Add configuration option to build on Linux on both big-endian and
4147 [Ralf Baechle <ralf@uni-koblenz.de>]
4149 *) Add the possibility to create shared libraries on HP-UX.
4152 Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
4154 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
4155 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
4156 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
4157 PRNG state recovery was possible based on the output of
4158 one PRNG request appropriately sized to gain knowledge on
4159 'md' followed by enough consecutive 1-byte PRNG requests
4160 to traverse all of 'state'.
4162 1. When updating 'md_local' (the current thread's copy of 'md')
4163 during PRNG output generation, hash all of the previous
4164 'md_local' value, not just the half used for PRNG output.
4166 2. Make the number of bytes from 'state' included into the hash
4167 independent from the number of PRNG bytes requested.
4169 The first measure alone would be sufficient to avoid
4170 Markku-Juhani's attack. (Actually it had never occurred
4171 to me that the half of 'md_local' used for chaining was the
4172 half from which PRNG output bytes were taken -- I had always
4173 assumed that the secret half would be used.) The second
4174 measure makes sure that additional data from 'state' is never
4175 mixed into 'md_local' in small portions; this heuristically
4176 further strengthens the PRNG.
4179 *) Fix crypto/bn/asm/mips3.s.
4182 *) When only the key is given to "enc", the IV is undefined. Print out
4183 an error message in this case.
4186 *) Handle special case when X509_NAME is empty in X509 printing routines.
4189 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
4190 positive and less than q.
4193 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
4194 used: it isn't thread safe and the add_lock_callback should handle
4196 [Paul Rose <Paul.Rose@bridge.com>]
4198 *) Verify that incoming data obeys the block size in
4199 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
4203 [Ulf Möller, Bodo Möller]
4205 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
4206 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
4207 when fixing the server behaviour for backwards-compatible 'client
4208 hello' messages. (Note that the attack is impractical against
4209 SSL 3.0 and TLS 1.0 anyway because length and version checking
4210 means that the probability of guessing a valid ciphertext is
4211 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
4214 Before 0.9.5, the countermeasure (hide the error by generating a
4215 random 'decryption result') did not work properly because
4216 ERR_clear_error() was missing, meaning that SSL_get_error() would
4217 detect the supposedly ignored error.
4219 Both problems are now fixed.
4222 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
4223 (previously it was 1024).
4226 *) Fix for compatibility mode trust settings: ignore trust settings
4227 unless some valid trust or reject settings are present.
4230 *) Fix for blowfish EVP: its a variable length cipher.
4233 *) Fix various bugs related to DSA S/MIME verification. Handle missing
4234 parameters in DSA public key structures and return an error in the
4235 DSA routines if parameters are absent.
4238 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
4239 in the current directory if neither $RANDFILE nor $HOME was set.
4240 RAND_file_name() in 0.9.6a returned NULL in this case. This has
4241 caused some confusion to Windows users who haven't defined $HOME.
4242 Thus RAND_file_name() is changed again: e_os.h can define a
4243 DEFAULT_HOME, which will be used if $HOME is not set.
4244 For Windows, we use "C:"; on other platforms, we still require
4245 environment variables.
4247 *) Move 'if (!initialized) RAND_poll()' into regions protected by
4248 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
4249 having multiple threads call RAND_poll() concurrently.
4252 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
4253 combination of a flag and a thread ID variable.
4254 Otherwise while one thread is in ssleay_rand_bytes (which sets the
4255 flag), *other* threads can enter ssleay_add_bytes without obeying
4256 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
4257 that they do not hold after the first thread unsets add_do_not_lock).
4260 *) Change bctest again: '-x' expressions are not available in all
4264 Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
4266 *) Fix a couple of memory leaks in PKCS7_dataDecode()
4267 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
4269 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
4270 the default extension for executables, if any. Also, make the perl
4271 scripts that use symlink() to test if it really exists and use "cp"
4272 if it doesn't. All this made OpenSSL compilable and installable in
4276 *) Fix for asn1_GetSequence() for indefinite length constructed data.
4277 If SEQUENCE is length is indefinite just set c->slen to the total
4278 amount of data available.
4279 [Steve Henson, reported by shige@FreeBSD.org]
4280 [This change does not apply to 0.9.7.]
4282 *) Change bctest to avoid here-documents inside command substitution
4283 (workaround for FreeBSD /bin/sh bug).
4284 For compatibility with Ultrix, avoid shell functions (introduced
4285 in the bctest version that searches along $PATH).
4288 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
4289 with des_encrypt() defined on some operating systems, like Solaris
4293 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
4294 On the Importance of Eliminating Errors in Cryptographic
4295 Computations, J. Cryptology 14 (2001) 2, 101-119,
4296 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
4299 *) MIPS assembler BIGNUM division bug fix.
4302 *) Disabled incorrect Alpha assembler code.
4305 *) Fix PKCS#7 decode routines so they correctly update the length
4306 after reading an EOC for the EXPLICIT tag.
4308 [This change does not apply to 0.9.7.]
4310 *) Fix bug in PKCS#12 key generation routines. This was triggered
4311 if a 3DES key was generated with a 0 initial byte. Include
4312 PKCS12_BROKEN_KEYGEN compilation option to retain the old
4313 (but broken) behaviour.
4316 *) Enhance bctest to search for a working bc along $PATH and print
4318 [Tim Rice <tim@multitalents.net> via Richard Levitte]
4320 *) Fix memory leaks in err.c: free err_data string if necessary;
4321 don't write to the wrong index in ERR_set_error_data.
4324 *) Implement ssl23_peek (analogous to ssl23_read), which previously
4328 *) Replace rdtsc with _emit statements for VC++ version 5.
4329 [Jeremy Cooper <jeremy@baymoo.org>]
4331 *) Make it possible to reuse SSLv2 sessions.
4334 *) In copy_email() check for >= 0 as a return value for
4335 X509_NAME_get_index_by_NID() since 0 is a valid index.
4336 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
4338 *) Avoid coredump with unsupported or invalid public keys by checking if
4339 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
4340 PKCS7_verify() fails with non detached data.
4343 *) Don't use getenv in library functions when run as setuid/setgid.
4344 New function OPENSSL_issetugid().
4347 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
4348 due to incorrect handling of multi-threading:
4350 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
4352 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
4354 3. Count how many times MemCheck_off() has been called so that
4355 nested use can be treated correctly. This also avoids
4356 inband-signalling in the previous code (which relied on the
4357 assumption that thread ID 0 is impossible).
4360 *) Add "-rand" option also to s_client and s_server.
4363 *) Fix CPU detection on Irix 6.x.
4364 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
4365 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
4367 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
4370 [This change does not apply to 0.9.7.]
4372 *) Use the cached encoding of an X509_NAME structure rather than
4373 copying it. This is apparently the reason for the libsafe "errors"
4374 but the code is actually correct.
4377 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
4378 Bleichenbacher's DSA attack.
4379 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
4380 to be set and top=0 forces the highest bit to be set; top=-1 is new
4381 and leaves the highest bit random.
4382 [Ulf Moeller, Bodo Moeller]
4384 *) In the NCONF_...-based implementations for CONF_... queries
4385 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
4386 a temporary CONF structure with the data component set to NULL
4387 (which gives segmentation faults in lh_retrieve).
4388 Instead, use NULL for the CONF pointer in CONF_get_string and
4389 CONF_get_number (which may use environment variables) and directly
4390 return NULL from CONF_get_section.
4393 *) Fix potential buffer overrun for EBCDIC.
4396 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
4397 keyUsage if basicConstraints absent for a CA.
4400 *) Make SMIME_write_PKCS7() write mail header values with a format that
4401 is more generally accepted (no spaces before the semicolon), since
4402 some programs can't parse those values properly otherwise. Also make
4403 sure BIO's that break lines after each write do not create invalid
4407 *) Make the CRL encoding routines work with empty SEQUENCE OF. The
4408 macros previously used would not encode an empty SEQUENCE OF
4409 and break the signature.
4411 [This change does not apply to 0.9.7.]
4413 *) Zero the premaster secret after deriving the master secret in
4417 *) Add some EVP_add_digest_alias registrations (as found in
4418 OpenSSL_add_all_digests()) to SSL_library_init()
4419 aka OpenSSL_add_ssl_algorithms(). This provides improved
4420 compatibility with peers using X.509 certificates
4421 with unconventional AlgorithmIdentifier OIDs.
4424 *) Fix for Irix with NO_ASM.
4425 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
4427 *) ./config script fixes.
4428 [Ulf Moeller, Richard Levitte]
4430 *) Fix 'openssl passwd -1'.
4433 *) Change PKCS12_key_gen_asc() so it can cope with non null
4434 terminated strings whose length is passed in the passlen
4435 parameter, for example from PEM callbacks. This was done
4436 by adding an extra length parameter to asc2uni().
4437 [Steve Henson, reported by <oddissey@samsung.co.kr>]
4439 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
4440 call failed, free the DSA structure.
4443 *) Fix to uni2asc() to cope with zero length Unicode strings.
4444 These are present in some PKCS#12 files.
4447 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
4448 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
4449 when writing a 32767 byte record.
4450 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
4452 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
4453 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
4455 (RSA objects have a reference count access to which is protected
4456 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
4457 so they are meant to be shared between threads.)
4458 [Bodo Moeller, Geoff Thorpe; original patch submitted by
4459 "Reddie, Steven" <Steven.Reddie@ca.com>]
4461 *) Fix a deadlock in CRYPTO_mem_leaks().
4464 *) Use better test patterns in bntest.
4467 *) rand_win.c fix for Borland C.
4470 *) BN_rshift bugfix for n == 0.
4473 *) Add a 'bctest' script that checks for some known 'bc' bugs
4474 so that 'make test' does not abort just because 'bc' is broken.
4477 *) Store verify_result within SSL_SESSION also for client side to
4478 avoid potential security hole. (Re-used sessions on the client side
4479 always resulted in verify_result==X509_V_OK, not using the original
4480 result of the server certificate verification.)
4483 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
4484 SSL3_RT_APPLICATION_DATA, return 0.
4485 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
4489 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
4490 releases, have been re-implemented by renaming the previous
4491 implementations of ssl2_read and ssl3_read to ssl2_read_internal
4492 and ssl3_read_internal, respectively, and adding 'peek' parameters
4493 to them. The new ssl[23]_{read,peek} functions are calls to
4494 ssl[23]_read_internal with the 'peek' flag set appropriately.
4495 A 'peek' parameter has also been added to ssl3_read_bytes, which
4496 does the actual work for ssl3_read_internal.
4499 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
4500 the method-specific "init()" handler. Also clean up ex_data after
4501 calling the method-specific "finish()" handler. Previously, this was
4502 happening the other way round.
4505 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
4506 The previous value, 12, was not always sufficient for BN_mod_exp().
4509 *) Make sure that shared libraries get the internal name engine with
4510 the full version number and not just 0. This should mark the
4511 shared libraries as not backward compatible. Of course, this should
4512 be changed again when we can guarantee backward binary compatibility.
4515 *) Fix typo in get_cert_by_subject() in by_dir.c
4516 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
4518 *) Rework the system to generate shared libraries:
4520 - Make note of the expected extension for the shared libraries and
4521 if there is a need for symbolic links from for example libcrypto.so.0
4522 to libcrypto.so.0.9.7. There is extended info in Configure for
4525 - Make as few rebuilds of the shared libraries as possible.
4527 - Still avoid linking the OpenSSL programs with the shared libraries.
4529 - When installing, install the shared libraries separately from the
4533 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
4535 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
4536 and not in SSL_clear because the latter is also used by the
4537 accept/connect functions; previously, the settings made by
4538 SSL_set_read_ahead would be lost during the handshake.
4539 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
4541 *) Correct util/mkdef.pl to be selective about disabled algorithms.
4542 Previously, it would create entries for disableed algorithms no
4546 *) Added several new manual pages for SSL_* function.
4549 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
4551 *) In ssl23_get_client_hello, generate an error message when faced
4552 with an initial SSL 3.0/TLS record that is too small to contain the
4553 first two bytes of the ClientHello message, i.e. client_version.
4554 (Note that this is a pathologic case that probably has never happened
4555 in real life.) The previous approach was to use the version number
4556 from the record header as a substitute; but our protocol choice
4557 should not depend on that one because it is not authenticated
4558 by the Finished messages.
4561 *) More robust randomness gathering functions for Windows.
4562 [Jeffrey Altman <jaltman@columbia.edu>]
4564 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
4565 not set then we don't setup the error code for issuer check errors
4566 to avoid possibly overwriting other errors which the callback does
4567 handle. If an application does set the flag then we assume it knows
4568 what it is doing and can handle the new informational codes
4572 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
4573 a general "ANY" type, as such it should be able to decode anything
4574 including tagged types. However it didn't check the class so it would
4575 wrongly interpret tagged types in the same way as their universal
4576 counterpart and unknown types were just rejected. Changed so that the
4577 tagged and unknown types are handled in the same way as a SEQUENCE:
4578 that is the encoding is stored intact. There is also a new type
4579 "V_ASN1_OTHER" which is used when the class is not universal, in this
4580 case we have no idea what the actual type is so we just lump them all
4584 *) On VMS, stdout may very well lead to a file that is written to
4585 in a record-oriented fashion. That means that every write() will
4586 write a separate record, which will be read separately by the
4587 programs trying to read from it. This can be very confusing.
4589 The solution is to put a BIO filter in the way that will buffer
4590 text until a linefeed is reached, and then write everything a
4591 line at a time, so every record written will be an actual line,
4592 not chunks of lines and not (usually doesn't happen, but I've
4593 seen it once) several lines in one record. BIO_f_linebuffer() is
4596 Currently, it's a VMS-only method, because that's where it has
4597 been tested well enough.
4600 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
4601 it can return incorrect results.
4602 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
4603 but it was in 0.9.6-beta[12].)
4606 *) Disable the check for content being present when verifying detached
4607 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
4608 include zero length content when signing messages.
4611 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
4612 BIO_ctrl (for BIO pairs).
4615 *) Add DSO method for VMS.
4618 *) Bug fix: Montgomery multiplication could produce results with the
4622 *) Add RPM specification openssl.spec and modify it to build three
4623 packages. The default package contains applications, application
4624 documentation and run-time libraries. The devel package contains
4625 include files, static libraries and function documentation. The
4626 doc package contains the contents of the doc directory. The original
4627 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
4630 *) Add a large number of documentation files for many SSL routines.
4631 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
4633 *) Add a configuration entry for Sony News 4.
4634 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
4636 *) Don't set the two most significant bits to one when generating a
4637 random number < q in the DSA library.
4640 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
4641 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
4642 the underlying transport is blocking) if a handshake took place.
4643 (The default behaviour is needed by applications such as s_client
4644 and s_server that use select() to determine when to use SSL_read;
4645 but for applications that know in advance when to expect data, it
4646 just makes things more complicated.)
4649 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
4653 *) Add a few more EBCDIC conditionals that make `req' and `x509'
4654 work better on such systems.
4655 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4657 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
4658 Update PKCS12_parse() so it copies the friendlyName and the
4659 keyid to the certificates aux info.
4662 *) Fix bug in PKCS7_verify() which caused an infinite loop
4663 if there was more than one signature.
4664 [Sven Uszpelkat <su@celocom.de>]
4666 *) Major change in util/mkdef.pl to include extra information
4667 about each symbol, as well as presentig variables as well
4668 as functions. This change means that there's n more need
4669 to rebuild the .num files when some algorithms are excluded.
4672 *) Allow the verify time to be set by an application,
4673 rather than always using the current time.
4676 *) Phase 2 verify code reorganisation. The certificate
4677 verify code now looks up an issuer certificate by a
4678 number of criteria: subject name, authority key id
4679 and key usage. It also verifies self signed certificates
4680 by the same criteria. The main comparison function is
4681 X509_check_issued() which performs these checks.
4683 Lot of changes were necessary in order to support this
4684 without completely rewriting the lookup code.
4686 Authority and subject key identifier are now cached.
4688 The LHASH 'certs' is X509_STORE has now been replaced
4689 by a STACK_OF(X509_OBJECT). This is mainly because an
4690 LHASH can't store or retrieve multiple objects with
4691 the same hash value.
4693 As a result various functions (which were all internal
4694 use only) have changed to handle the new X509_STORE
4695 structure. This will break anything that messed round
4696 with X509_STORE internally.
4698 The functions X509_STORE_add_cert() now checks for an
4699 exact match, rather than just subject name.
4701 The X509_STORE API doesn't directly support the retrieval
4702 of multiple certificates matching a given criteria, however
4703 this can be worked round by performing a lookup first
4704 (which will fill the cache with candidate certificates)
4705 and then examining the cache for matches. This is probably
4706 the best we can do without throwing out X509_LOOKUP
4707 entirely (maybe later...).
4709 The X509_VERIFY_CTX structure has been enhanced considerably.
4711 All certificate lookup operations now go via a get_issuer()
4712 callback. Although this currently uses an X509_STORE it
4713 can be replaced by custom lookups. This is a simple way
4714 to bypass the X509_STORE hackery necessary to make this
4715 work and makes it possible to use more efficient techniques
4716 in future. A very simple version which uses a simple
4717 STACK for its trusted certificate store is also provided
4718 using X509_STORE_CTX_trusted_stack().
4720 The verify_cb() and verify() callbacks now have equivalents
4721 in the X509_STORE_CTX structure.
4723 X509_STORE_CTX also has a 'flags' field which can be used
4724 to customise the verify behaviour.
4727 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
4728 excludes S/MIME capabilities.
4731 *) When a certificate request is read in keep a copy of the
4732 original encoding of the signed data and use it when outputing
4733 again. Signatures then use the original encoding rather than
4734 a decoded, encoded version which may cause problems if the
4735 request is improperly encoded.
4738 *) For consistency with other BIO_puts implementations, call
4739 buffer_write(b, ...) directly in buffer_puts instead of calling
4742 In BIO_puts, increment b->num_write as in BIO_write.
4743 [Peter.Sylvester@EdelWeb.fr]
4745 *) Fix BN_mul_word for the case where the word is 0. (We have to use
4746 BN_zero, we may not return a BIGNUM with an array consisting of
4750 *) Avoid calling abort() from within the library when problems are
4751 detected, except if preprocessor symbols have been defined
4752 (such as REF_CHECK, BN_DEBUG etc.).
4755 *) New openssl application 'rsautl'. This utility can be
4756 used for low level RSA operations. DER public key
4757 BIO/fp routines also added.
4760 *) New Configure entry and patches for compiling on QNX 4.
4761 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
4763 *) A demo state-machine implementation was sponsored by
4764 Nuron (http://www.nuron.com/) and is now available in
4765 demos/state_machine.
4768 *) New options added to the 'dgst' utility for signature
4769 generation and verification.
4772 *) Unrecognized PKCS#7 content types are now handled via a
4773 catch all ASN1_TYPE structure. This allows unsupported
4774 types to be stored as a "blob" and an application can
4775 encode and decode it manually.
4778 *) Fix various signed/unsigned issues to make a_strex.c
4780 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
4782 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
4783 length if passed a buffer. ASN1_INTEGER_to_BN failed
4784 if passed a NULL BN and its argument was negative.
4785 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
4787 *) Modification to PKCS#7 encoding routines to output definite
4788 length encoding. Since currently the whole structures are in
4789 memory there's not real point in using indefinite length
4790 constructed encoding. However if OpenSSL is compiled with
4791 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
4794 *) Added BIO_vprintf() and BIO_vsnprintf().
4797 *) Added more prefixes to parse for in the the strings written
4798 through a logging bio, to cover all the levels that are available
4799 through syslog. The prefixes are now:
4801 PANIC, EMERG, EMR => LOG_EMERG
4802 ALERT, ALR => LOG_ALERT
4803 CRIT, CRI => LOG_CRIT
4804 ERROR, ERR => LOG_ERR
4805 WARNING, WARN, WAR => LOG_WARNING
4806 NOTICE, NOTE, NOT => LOG_NOTICE
4807 INFO, INF => LOG_INFO
4808 DEBUG, DBG => LOG_DEBUG
4810 and as before, if none of those prefixes are present at the
4811 beginning of the string, LOG_ERR is chosen.
4813 On Win32, the LOG_* levels are mapped according to this:
4815 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
4816 LOG_WARNING => EVENTLOG_WARNING_TYPE
4817 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
4821 *) Made it possible to reconfigure with just the configuration
4822 argument "reconf" or "reconfigure". The command line arguments
4823 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
4824 and are retrieved from there when reconfiguring.
4828 [Assar Westerlund <assar@sics.se>, Richard Levitte]
4830 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
4833 *) The obj_dat.pl script was messing up the sorting of object
4834 names. The reason was that it compared the quoted version
4835 of strings as a result "OCSP" > "OCSP Signing" because
4836 " > SPACE. Changed script to store unquoted versions of
4837 names and add quotes on output. It was also omitting some
4838 names from the lookup table if they were given a default
4839 value (that is if SN is missing it is given the same
4840 value as LN and vice versa), these are now added on the
4841 grounds that if an object has a name we should be able to
4842 look it up. Finally added warning output when duplicate
4843 short or long names are found.
4846 *) Changes needed for Tandem NSK.
4847 [Scott Uroff <scott@xypro.com>]
4849 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
4850 RSA_padding_check_SSLv23(), special padding was never detected
4851 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
4852 version rollback attacks was not effective.
4854 In s23_clnt.c, don't use special rollback-attack detection padding
4855 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
4856 client; similarly, in s23_srvr.c, don't do the rollback check if
4857 SSL 2.0 is the only protocol enabled in the server.
4860 *) Make it possible to get hexdumps of unprintable data with 'openssl
4861 asn1parse'. By implication, the functions ASN1_parse_dump() and
4862 BIO_dump_indent() are added.
4865 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
4866 these print out strings and name structures based on various
4867 flags including RFC2253 support and proper handling of
4868 multibyte characters. Added options to the 'x509' utility
4869 to allow the various flags to be set.
4872 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
4873 Also change the functions X509_cmp_current_time() and
4874 X509_gmtime_adj() work with an ASN1_TIME structure,
4875 this will enable certificates using GeneralizedTime in validity
4876 dates to be checked.
4879 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
4880 negative public key encodings) on by default,
4881 NO_NEG_PUBKEY_BUG can be set to disable it.
4884 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
4885 content octets. An i2c_ASN1_OBJECT is unnecessary because
4886 the encoding can be trivially obtained from the structure.
4889 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
4890 not read locks (CRYPTO_r_[un]lock).
4893 *) A first attempt at creating official support for shared
4894 libraries through configuration. I've kept it so the
4895 default is static libraries only, and the OpenSSL programs
4896 are always statically linked for now, but there are
4897 preparations for dynamic linking in place.
4898 This has been tested on Linux and Tru64.
4901 *) Randomness polling function for Win9x, as described in:
4902 Peter Gutmann, Software Generation of Practically Strong
4906 *) Fix so PRNG is seeded in req if using an already existing
4910 *) New options to smime application. -inform and -outform
4911 allow alternative formats for the S/MIME message including
4912 PEM and DER. The -content option allows the content to be
4913 specified separately. This should allow things like Netscape
4914 form signing output easier to verify.
4917 *) Fix the ASN1 encoding of tags using the 'long form'.
4920 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
4921 STRING types. These convert content octets to and from the
4922 underlying type. The actual tag and length octets are
4923 already assumed to have been read in and checked. These
4924 are needed because all other string types have virtually
4925 identical handling apart from the tag. By having versions
4926 of the ASN1 functions that just operate on content octets
4927 IMPLICIT tagging can be handled properly. It also allows
4928 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
4929 and ASN1_INTEGER are identical apart from the tag.
4932 *) Change the handling of OID objects as follows:
4934 - New object identifiers are inserted in objects.txt, following
4935 the syntax given in objects.README.
4936 - objects.pl is used to process obj_mac.num and create a new
4938 - obj_dat.pl is used to create a new obj_dat.h, using the data in
4941 This is currently kind of a hack, and the perl code in objects.pl
4942 isn't very elegant, but it works as I intended. The simplest way
4943 to check that it worked correctly is to look in obj_dat.h and
4944 check the array nid_objs and make sure the objects haven't moved
4945 around (this is important!). Additions are OK, as well as
4946 consistent name changes.
4949 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
4952 *) Addition of the command line parameter '-rand file' to 'openssl req'.
4953 The given file adds to whatever has already been seeded into the
4954 random pool through the RANDFILE configuration file option or
4955 environment variable, or the default random state file.
4958 *) mkstack.pl now sorts each macro group into lexical order.
4959 Previously the output order depended on the order the files
4960 appeared in the directory, resulting in needless rewriting
4964 *) Patches to make OpenSSL compile under Win32 again. Mostly
4965 work arounds for the VC++ problem that it treats func() as
4966 func(void). Also stripped out the parts of mkdef.pl that
4967 added extra typesafe functions: these no longer exist.
4970 *) Reorganisation of the stack code. The macros are now all
4971 collected in safestack.h . Each macro is defined in terms of
4972 a "stack macro" of the form SKM_<name>(type, a, b). The
4973 DEBUG_SAFESTACK is now handled in terms of function casts,
4974 this has the advantage of retaining type safety without the
4975 use of additional functions. If DEBUG_SAFESTACK is not defined
4976 then the non typesafe macros are used instead. Also modified the
4977 mkstack.pl script to handle the new form. Needs testing to see
4978 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
4979 the default if no major problems. Similar behaviour for ASN1_SET_OF
4980 and PKCS12_STACK_OF.
4983 *) When some versions of IIS use the 'NET' form of private key the
4984 key derivation algorithm is different. Normally MD5(password) is
4985 used as a 128 bit RC4 key. In the modified case
4986 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
4987 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
4988 as the old Netscape_RSA functions except they have an additional
4989 'sgckey' parameter which uses the modified algorithm. Also added
4990 an -sgckey command line option to the rsa utility. Thanks to
4991 Adrian Peck <bertie@ncipher.com> for posting details of the modified
4992 algorithm to openssl-dev.
4995 *) The evp_local.h macros were using 'c.##kname' which resulted in
4996 invalid expansion on some systems (SCO 5.0.5 for example).
4997 Corrected to 'c.kname'.
4998 [Phillip Porch <root@theporch.com>]
5000 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
5001 a STACK of email addresses from a certificate or request, these look
5002 in the subject name and the subject alternative name extensions and
5003 omit any duplicate addresses.
5006 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
5007 This makes DSA verification about 2 % faster.
5010 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
5011 (meaning that now 2^5 values will be precomputed, which is only 4 KB
5012 plus overhead for 1024 bit moduli).
5013 This makes exponentiations about 0.5 % faster for 1024 bit
5014 exponents (as measured by "openssl speed rsa2048").
5017 *) Rename memory handling macros to avoid conflicts with other
5019 Malloc => OPENSSL_malloc
5020 Malloc_locked => OPENSSL_malloc_locked
5021 Realloc => OPENSSL_realloc
5022 Free => OPENSSL_free
5025 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
5026 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
5029 *) CygWin32 support.
5030 [John Jarvie <jjarvie@newsguy.com>]
5032 *) The type-safe stack code has been rejigged. It is now only compiled
5033 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
5034 by default all type-specific stack functions are "#define"d back to
5035 standard stack functions. This results in more streamlined output
5036 but retains the type-safety checking possibilities of the original
5040 *) The STACK code has been cleaned up, and certain type declarations
5041 that didn't make a lot of sense have been brought in line. This has
5042 also involved a cleanup of sorts in safestack.h to more correctly
5043 map type-safe stack functions onto their plain stack counterparts.
5044 This work has also resulted in a variety of "const"ifications of
5045 lots of the code, especially "_cmp" operations which should normally
5046 be prototyped with "const" parameters anyway.
5049 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
5050 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
5051 (The PRNG state consists of two parts, the large pool 'state' and 'md',
5052 where all of 'md' is used each time the PRNG is used, but 'state'
5053 is used only indexed by a cyclic counter. As entropy may not be
5054 well distributed from the beginning, 'md' is important as a
5055 chaining variable. However, the output function chains only half
5056 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
5057 all of 'md', and seeding with STATE_SIZE dummy bytes will result
5058 in all of 'state' being rewritten, with the new values depending
5059 on virtually all of 'md'. This overcomes the 80 bit limitation.)
5062 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
5063 the handshake is continued after ssl_verify_cert_chain();
5064 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
5065 can lead to 'unexplainable' connection aborts later.
5066 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
5068 *) Major EVP API cipher revision.
5069 Add hooks for extra EVP features. This allows various cipher
5070 parameters to be set in the EVP interface. Support added for variable
5071 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
5072 setting of RC2 and RC5 parameters.
5074 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
5077 Remove lots of duplicated code from the EVP library. For example *every*
5078 cipher init() function handles the 'iv' in the same way according to the
5079 cipher mode. They also all do nothing if the 'key' parameter is NULL and
5080 for CFB and OFB modes they zero ctx->num.
5082 New functionality allows removal of S/MIME code RC2 hack.
5084 Most of the routines have the same form and so can be declared in terms
5087 By shifting this to the top level EVP_CipherInit() it can be removed from
5088 all individual ciphers. If the cipher wants to handle IVs or keys
5089 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
5092 Change lots of functions like EVP_EncryptUpdate() to now return a
5093 value: although software versions of the algorithms cannot fail
5094 any installed hardware versions can.
5097 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
5098 this option is set, tolerate broken clients that send the negotiated
5099 protocol version number instead of the requested protocol version
5103 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
5104 i.e. non-zero for export ciphersuites, zero otherwise.
5105 Previous versions had this flag inverted, inconsistent with
5106 rsa_tmp_cb (..._TMP_RSA_CB).
5107 [Bodo Moeller; problem reported by Amit Chopra]
5109 *) Add missing DSA library text string. Work around for some IIS
5110 key files with invalid SEQUENCE encoding.
5113 *) Add a document (doc/standards.txt) that list all kinds of standards
5114 and so on that are implemented in OpenSSL.
5117 *) Enhance c_rehash script. Old version would mishandle certificates
5118 with the same subject name hash and wouldn't handle CRLs at all.
5119 Added -fingerprint option to crl utility, to support new c_rehash
5123 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
5126 *) Fix for SSL server purpose checking. Server checking was
5127 rejecting certificates which had extended key usage present
5128 but no ssl client purpose.
5129 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
5131 *) Make PKCS#12 code work with no password. The PKCS#12 spec
5132 is a little unclear about how a blank password is handled.
5133 Since the password in encoded as a BMPString with terminating
5134 double NULL a zero length password would end up as just the
5135 double NULL. However no password at all is different and is
5136 handled differently in the PKCS#12 key generation code. NS
5137 treats a blank password as zero length. MSIE treats it as no
5138 password on export: but it will try both on import. We now do
5139 the same: PKCS12_parse() tries zero length and no password if
5140 the password is set to "" or NULL (NULL is now a valid password:
5141 it wasn't before) as does the pkcs12 application.
5144 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
5145 perror when PEM_read_bio_X509_REQ fails, the error message must
5146 be obtained from the error queue.
5149 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
5150 it in ERR_remove_state if appropriate, and change ERR_get_state
5151 accordingly to avoid race conditions (this is necessary because
5152 thread_hash is no longer constant once set).
5155 *) Bugfix for linux-elf makefile.one.
5158 *) RSA_get_default_method() will now cause a default
5159 RSA_METHOD to be chosen if one doesn't exist already.
5160 Previously this was only set during a call to RSA_new()
5161 or RSA_new_method(NULL) meaning it was possible for
5162 RSA_get_default_method() to return NULL.
5165 *) Added native name translation to the existing DSO code
5166 that will convert (if the flag to do so is set) filenames
5167 that are sufficiently small and have no path information
5168 into a canonical native form. Eg. "blah" converted to
5169 "libblah.so" or "blah.dll" etc.
5172 *) New function ERR_error_string_n(e, buf, len) which is like
5173 ERR_error_string(e, buf), but writes at most 'len' bytes
5174 including the 0 terminator. For ERR_error_string_n, 'buf'
5176 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
5178 *) CONF library reworked to become more general. A new CONF
5179 configuration file reader "class" is implemented as well as a
5180 new functions (NCONF_*, for "New CONF") to handle it. The now
5181 old CONF_* functions are still there, but are reimplemented to
5182 work in terms of the new functions. Also, a set of functions
5183 to handle the internal storage of the configuration data is
5184 provided to make it easier to write new configuration file
5185 reader "classes" (I can definitely see something reading a
5186 configuration file in XML format, for example), called _CONF_*,
5187 or "the configuration storage API"...
5189 The new configuration file reading functions are:
5191 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
5192 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
5194 NCONF_default, NCONF_WIN32
5196 NCONF_dump_fp, NCONF_dump_bio
5198 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
5199 NCONF_new creates a new CONF object. This works in the same way
5200 as other interfaces in OpenSSL, like the BIO interface.
5201 NCONF_dump_* dump the internal storage of the configuration file,
5202 which is useful for debugging. All other functions take the same
5203 arguments as the old CONF_* functions wth the exception of the
5204 first that must be a `CONF *' instead of a `LHASH *'.
5206 To make it easer to use the new classes with the old CONF_* functions,
5207 the function CONF_set_default_method is provided.
5210 *) Add '-tls1' option to 'openssl ciphers', which was already
5211 mentioned in the documentation but had not been implemented.
5212 (This option is not yet really useful because even the additional
5213 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
5216 *) Initial DSO code added into libcrypto for letting OpenSSL (and
5217 OpenSSL-based applications) load shared libraries and bind to
5218 them in a portable way.
5219 [Geoff Thorpe, with contributions from Richard Levitte]
5221 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
5223 *) Make sure _lrotl and _lrotr are only used with MSVC.
5225 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
5226 (the default implementation of RAND_status).
5228 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
5229 to '-clrext' (= clear extensions), as intended and documented.
5230 [Bodo Moeller; inconsistency pointed out by Michael Attili
5233 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
5234 was larger than the MD block size.
5235 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
5237 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
5238 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
5239 using the passed key: if the passed key was a private key the result
5240 of X509_print(), for example, would be to print out all the private key
5244 *) des_quad_cksum() byte order bug fix.
5245 [Ulf Möller, using the problem description in krb4-0.9.7, where
5246 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
5248 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
5250 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
5252 *) For easily testing in shell scripts whether some command
5253 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
5254 returns with exit code 0 iff no command of the given name is available.
5255 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
5256 the output goes to stdout and nothing is printed to stderr.
5257 Additional arguments are always ignored.
5259 Since for each cipher there is a command of the same name,
5260 the 'no-cipher' compilation switches can be tested this way.
5262 ('openssl no-XXX' is not able to detect pseudo-commands such
5263 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
5266 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
5269 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
5270 is set; it will be thrown away anyway because each handshake creates
5272 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
5273 to parameters -- in previous versions (since OpenSSL 0.9.3) the
5274 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
5275 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
5278 *) New s_client option -ign_eof: EOF at stdin is ignored, and
5279 'Q' and 'R' lose their special meanings (quit/renegotiate).
5280 This is part of what -quiet does; unlike -quiet, -ign_eof
5281 does not suppress any output.
5284 *) Add compatibility options to the purpose and trust code. The
5285 purpose X509_PURPOSE_ANY is "any purpose" which automatically
5286 accepts a certificate or CA, this was the previous behaviour,
5287 with all the associated security issues.
5289 X509_TRUST_COMPAT is the old trust behaviour: only and
5290 automatically trust self signed roots in certificate store. A
5291 new trust setting X509_TRUST_DEFAULT is used to specify that
5292 a purpose has no associated trust setting and it should instead
5293 use the value in the default purpose.
5296 *) Fix the PKCS#8 DSA private key code so it decodes keys again
5297 and fix a memory leak.
5300 *) In util/mkerr.pl (which implements 'make errors'), preserve
5301 reason strings from the previous version of the .c file, as
5302 the default to have only downcase letters (and digits) in
5303 automatically generated reasons codes is not always appropriate.
5306 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
5307 using strerror. Previously, ERR_reason_error_string() returned
5308 library names as reason strings for SYSerr; but SYSerr is a special
5309 case where small numbers are errno values, not library numbers.
5312 *) Add '-dsaparam' option to 'openssl dhparam' application. This
5313 converts DSA parameters into DH parameters. (When creating parameters,
5314 DSA_generate_parameters is used.)
5317 *) Include 'length' (recommended exponent length) in C code generated
5318 by 'openssl dhparam -C'.
5321 *) The second argument to set_label in perlasm was already being used
5322 so couldn't be used as a "file scope" flag. Moved to third argument
5326 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
5327 instead of RAND_bytes for encryption IVs and salts.
5330 *) Include RAND_status() into RAND_METHOD instead of implementing
5331 it only for md_rand.c Otherwise replacing the PRNG by calling
5332 RAND_set_rand_method would be impossible.
5335 *) Don't let DSA_generate_key() enter an infinite loop if the random
5336 number generation fails.
5339 *) New 'rand' application for creating pseudo-random output.
5342 *) Added configuration support for Linux/IA64
5343 [Rolf Haberrecker <rolf@suse.de>]
5345 *) Assembler module support for Mingw32.
5348 *) Shared library support for HPUX (in shlib/).
5349 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
5351 *) Shared library support for Solaris gcc.
5352 [Lutz Behnke <behnke@trustcenter.de>]
5354 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
5356 *) PKCS7_encrypt() was adding text MIME headers twice because they
5357 were added manually and by SMIME_crlf_copy().
5360 *) In bntest.c don't call BN_rand with zero bits argument.
5361 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
5363 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
5364 case was implemented. This caused BN_div_recp() to fail occasionally.
5367 *) Add an optional second argument to the set_label() in the perl
5368 assembly language builder. If this argument exists and is set
5369 to 1 it signals that the assembler should use a symbol whose
5370 scope is the entire file, not just the current function. This
5371 is needed with MASM which uses the format label:: for this scope.
5372 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
5374 *) Change the ASN1 types so they are typedefs by default. Before
5375 almost all types were #define'd to ASN1_STRING which was causing
5376 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
5380 *) Change names of new functions to the new get1/get0 naming
5381 convention: After 'get1', the caller owns a reference count
5382 and has to call ..._free; 'get0' returns a pointer to some
5383 data structure without incrementing reference counters.
5384 (Some of the existing 'get' functions increment a reference
5385 counter, some don't.)
5386 Similarly, 'set1' and 'add1' functions increase reference
5387 counters or duplicate objects.
5390 *) Allow for the possibility of temp RSA key generation failure:
5391 the code used to assume it always worked and crashed on failure.
5394 *) Fix potential buffer overrun problem in BIO_printf().
5395 [Ulf Möller, using public domain code by Patrick Powell; problem
5396 pointed out by David Sacerdote <das33@cornell.edu>]
5398 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
5399 RAND_egd() and RAND_status(). In the command line application,
5400 the EGD socket can be specified like a seed file using RANDFILE
5404 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
5405 Some CAs (e.g. Verisign) distribute certificates in this form.
5408 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
5409 list to exclude them. This means that no special compilation option
5410 is needed to use anonymous DH: it just needs to be included in the
5414 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
5415 EVP_MD_type. The old functionality is available in a new macro called
5416 EVP_MD_md(). Change code that uses it and update docs.
5419 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
5420 where the 'void *' argument is replaced by a function pointer argument.
5421 Previously 'void *' was abused to point to functions, which works on
5422 many platforms, but is not correct. As these functions are usually
5423 called by macros defined in OpenSSL header files, most source code
5424 should work without changes.
5427 *) <openssl/opensslconf.h> (which is created by Configure) now contains
5428 sections with information on -D... compiler switches used for
5429 compiling the library so that applications can see them. To enable
5430 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
5431 must be defined. E.g.,
5432 #define OPENSSL_ALGORITHM_DEFINES
5433 #include <openssl/opensslconf.h>
5434 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
5435 [Richard Levitte, Ulf and Bodo Möller]
5437 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
5441 *) Change the 'other' type in certificate aux info to a STACK_OF
5442 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
5443 the required ASN1 format: arbitrary types determined by an OID.
5446 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
5447 argument to 'req'. This is not because the function is newer or
5448 better than others it just uses the work 'NEW' in the certificate
5449 request header lines. Some software needs this.
5452 *) Reorganise password command line arguments: now passwords can be
5453 obtained from various sources. Delete the PEM_cb function and make
5454 it the default behaviour: i.e. if the callback is NULL and the
5455 usrdata argument is not NULL interpret it as a null terminated pass
5456 phrase. If usrdata and the callback are NULL then the pass phrase
5457 is prompted for as usual.
5460 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
5461 the support is automatically enabled. The resulting binaries will
5462 autodetect the card and use it if present.
5463 [Ben Laurie and Compaq Inc.]
5465 *) Work around for Netscape hang bug. This sends certificate request
5466 and server done in one record. Since this is perfectly legal in the
5467 SSL/TLS protocol it isn't a "bug" option and is on by default. See
5468 the bugs/SSLv3 entry for more info.
5471 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
5474 *) Add -rand argument to smime and pkcs12 applications and read/write
5478 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
5481 *) Add command line password options to the remaining applications.
5484 *) Bug fix for BN_div_recp() for numerators with an even number of
5488 *) More tests in bntest.c, and changed test_bn output.
5491 *) ./config recognizes MacOS X now.
5494 *) Bug fix for BN_div() when the first words of num and divsor are
5495 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
5498 *) Add support for various broken PKCS#8 formats, and command line
5499 options to produce them.
5502 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
5503 get temporary BIGNUMs from a BN_CTX.
5506 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
5510 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
5511 include a #define from the old name to the new. The original intent
5512 was that statically linked binaries could for example just call
5513 SSLeay_add_all_ciphers() to just add ciphers to the table and not
5514 link with digests. This never worked becayse SSLeay_add_all_digests()
5515 and SSLeay_add_all_ciphers() were in the same source file so calling
5516 one would link with the other. They are now in separate source files.
5519 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
5522 *) Use a less unusual form of the Miller-Rabin primality test (it used
5523 a binary algorithm for exponentiation integrated into the Miller-Rabin
5524 loop, our standard modexp algorithms are faster).
5527 *) Support for the EBCDIC character set completed.
5528 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
5530 *) Source code cleanups: use const where appropriate, eliminate casts,
5531 use void * instead of char * in lhash.
5534 *) Bugfix: ssl3_send_server_key_exchange was not restartable
5535 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
5536 this the server could overwrite ephemeral keys that the client
5540 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
5541 using 50 iterations of the Rabin-Miller test.
5543 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
5544 iterations of the Rabin-Miller test as required by the appendix
5545 to FIPS PUB 186[-1]) instead of DSA_is_prime.
5546 As BN_is_prime_fasttest includes trial division, DSA parameter
5547 generation becomes much faster.
5549 This implies a change for the callback functions in DSA_is_prime
5550 and DSA_generate_parameters: The callback function is called once
5551 for each positive witness in the Rabin-Miller test, not just
5552 occasionally in the inner loop; and the parameters to the
5553 callback function now provide an iteration count for the outer
5554 loop rather than for the current invocation of the inner loop.
5555 DSA_generate_parameters additionally can call the callback
5556 function with an 'iteration count' of -1, meaning that a
5557 candidate has passed the trial division test (when q is generated
5558 from an application-provided seed, trial division is skipped).
5561 *) New function BN_is_prime_fasttest that optionally does trial
5562 division before starting the Rabin-Miller test and has
5563 an additional BN_CTX * argument (whereas BN_is_prime always
5564 has to allocate at least one BN_CTX).
5565 'callback(1, -1, cb_arg)' is called when a number has passed the
5566 trial division stage.
5569 *) Fix for bug in CRL encoding. The validity dates weren't being handled
5573 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
5576 *) New function BN_pseudo_rand().
5579 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
5580 bignum version of BN_from_montgomery() with the working code from
5581 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
5585 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
5586 made it impossible to use the same SSL_SESSION data structure in
5587 SSL2 clients in multiple threads.
5590 *) The return value of RAND_load_file() no longer counts bytes obtained
5591 by stat(). RAND_load_file(..., -1) is new and uses the complete file
5592 to seed the PRNG (previously an explicit byte count was required).
5593 [Ulf Möller, Bodo Möller]
5595 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
5596 used (char *) instead of (void *) and had casts all over the place.
5599 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
5602 *) Retain source code compatibility for BN_prime_checks macro:
5603 BN_is_prime(..., BN_prime_checks, ...) now uses
5604 BN_prime_checks_for_size to determine the appropriate number of
5605 Rabin-Miller iterations.
5608 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
5609 DH_CHECK_P_NOT_SAFE_PRIME.
5610 (Check if this is true? OpenPGP calls them "strong".)
5613 *) Merge the functionality of "dh" and "gendh" programs into a new program
5614 "dhparam". The old programs are retained for now but will handle DH keys
5615 (instead of parameters) in future.
5618 *) Make the ciphers, s_server and s_client programs check the return values
5619 when a new cipher list is set.
5622 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
5623 ciphers. Before when the 56bit ciphers were enabled the sorting was
5626 The syntax for the cipher sorting has been extended to support sorting by
5627 cipher-strength (using the strength_bits hard coded in the tables).
5628 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
5630 Fix a bug in the cipher-command parser: when supplying a cipher command
5631 string with an "undefined" symbol (neither command nor alphanumeric
5632 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
5633 an error is flagged.
5635 Due to the strength-sorting extension, the code of the
5636 ssl_create_cipher_list() function was completely rearranged. I hope that
5637 the readability was also increased :-)
5638 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
5640 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
5641 for the first serial number and places 2 in the serial number file. This
5642 avoids problems when the root CA is created with serial number zero and
5643 the first user certificate has the same issuer name and serial number
5647 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
5648 the new code. Add documentation for this stuff.
5651 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
5652 X509_*() to X509at_*() on the grounds that they don't handle X509
5653 structures and behave in an analagous way to the X509v3 functions:
5654 they shouldn't be called directly but wrapper functions should be used
5657 So we also now have some wrapper functions that call the X509at functions
5658 when passed certificate requests. (TO DO: similar things can be done with
5659 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
5660 things. Some of these need some d2i or i2d and print functionality
5661 because they handle more complex structures.)
5664 *) Add missing #ifndefs that caused missing symbols when building libssl
5665 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
5666 NO_RSA in ssl/s2*.c.
5667 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
5669 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
5670 has a return value which indicates the quality of the random data
5671 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
5672 error queue. New function RAND_pseudo_bytes() generates output that is
5673 guaranteed to be unique but not unpredictable. RAND_add is like
5674 RAND_seed, but takes an extra argument for an entropy estimate
5675 (RAND_seed always assumes full entropy).
5678 *) Do more iterations of Rabin-Miller probable prime test (specifically,
5679 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
5680 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
5681 in crypto/bn/bn_prime.c for the complete table). This guarantees a
5682 false-positive rate of at most 2^-80 for random input.
5685 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
5688 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
5689 in the 0.9.5 release), this returns the chain
5690 from an X509_CTX structure with a dup of the stack and all
5691 the X509 reference counts upped: so the stack will exist
5692 after X509_CTX_cleanup() has been called. Modify pkcs12.c
5695 Also make SSL_SESSION_print() print out the verify return
5699 *) Add manpage for the pkcs12 command. Also change the default
5700 behaviour so MAC iteration counts are used unless the new
5701 -nomaciter option is used. This improves file security and
5702 only older versions of MSIE (4.0 for example) need it.
5705 *) Honor the no-xxx Configure options when creating .DEF files.
5708 *) Add PKCS#10 attributes to field table: challengePassword,
5709 unstructuredName and unstructuredAddress. These are taken from
5710 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
5711 international characters are used.
5713 More changes to X509_ATTRIBUTE code: allow the setting of types
5714 based on strings. Remove the 'loc' parameter when adding
5715 attributes because these will be a SET OF encoding which is sorted
5719 *) Initial changes to the 'req' utility to allow request generation
5720 automation. This will allow an application to just generate a template
5721 file containing all the field values and have req construct the
5724 Initial support for X509_ATTRIBUTE handling. Stacks of these are
5725 used all over the place including certificate requests and PKCS#7
5726 structures. They are currently handled manually where necessary with
5727 some primitive wrappers for PKCS#7. The new functions behave in a
5728 manner analogous to the X509 extension functions: they allow
5729 attributes to be looked up by NID and added.
5731 Later something similar to the X509V3 code would be desirable to
5732 automatically handle the encoding, decoding and printing of the
5733 more complex types. The string types like challengePassword can
5734 be handled by the string table functions.
5736 Also modified the multi byte string table handling. Now there is
5737 a 'global mask' which masks out certain types. The table itself
5738 can use the flag STABLE_NO_MASK to ignore the mask setting: this
5739 is useful when for example there is only one permissible type
5740 (as in countryName) and using the mask might result in no valid
5744 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
5745 SSL_get_peer_finished to allow applications to obtain the latest
5746 Finished messages sent to the peer or expected from the peer,
5747 respectively. (SSL_get_peer_finished is usually the Finished message
5748 actually received from the peer, otherwise the protocol will be aborted.)
5750 As the Finished message are message digests of the complete handshake
5751 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
5752 be used for external authentication procedures when the authentication
5753 provided by SSL/TLS is not desired or is not enough.
5756 *) Enhanced support for Alpha Linux is added. Now ./config checks if
5757 the host supports BWX extension and if Compaq C is present on the
5758 $PATH. Just exploiting of the BWX extension results in 20-30%
5759 performance kick for some algorithms, e.g. DES and RC4 to mention
5760 a couple. Compaq C in turn generates ~20% faster code for MD5 and
5764 *) Add support for MS "fast SGC". This is arguably a violation of the
5765 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
5766 weak crypto and after checking the certificate is SGC a second one
5767 with strong crypto. MS SGC stops the first handshake after receiving
5768 the server certificate message and sends a second client hello. Since
5769 a server will typically do all the time consuming operations before
5770 expecting any further messages from the client (server key exchange
5771 is the most expensive) there is little difference between the two.
5773 To get OpenSSL to support MS SGC we have to permit a second client
5774 hello message after we have sent server done. In addition we have to
5775 reset the MAC if we do get this second client hello.
5778 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
5779 if a DER encoded private key is RSA or DSA traditional format. Changed
5780 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
5781 format DER encoded private key. Newer code should use PKCS#8 format which
5782 has the key type encoded in the ASN1 structure. Added DER private key
5783 support to pkcs8 application.
5786 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
5787 ciphersuites has been selected (as required by the SSL 3/TLS 1
5788 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
5789 is set, we interpret this as a request to violate the specification
5790 (the worst that can happen is a handshake failure, and 'correct'
5791 behaviour would result in a handshake failure anyway).
5794 *) In SSL_CTX_add_session, take into account that there might be multiple
5795 SSL_SESSION structures with the same session ID (e.g. when two threads
5796 concurrently obtain them from an external cache).
5797 The internal cache can handle only one SSL_SESSION with a given ID,
5798 so if there's a conflict, we now throw out the old one to achieve
5802 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
5803 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
5804 some routines that use cipher OIDs: some ciphers do not have OIDs
5805 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
5809 *) Simplify the trust setting structure and code. Now we just have
5810 two sequences of OIDs for trusted and rejected settings. These will
5811 typically have values the same as the extended key usage extension
5812 and any application specific purposes.
5814 The trust checking code now has a default behaviour: it will just
5815 check for an object with the same NID as the passed id. Functions can
5816 be provided to override either the default behaviour or the behaviour
5817 for a given id. SSL client, server and email already have functions
5818 in place for compatibility: they check the NID and also return "trusted"
5819 if the certificate is self signed.
5822 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
5823 traditional format into an EVP_PKEY structure.
5826 *) Add a password callback function PEM_cb() which either prompts for
5827 a password if usr_data is NULL or otherwise assumes it is a null
5828 terminated password. Allow passwords to be passed on command line
5829 environment or config files in a few more utilities.
5832 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
5833 keys. Add some short names for PKCS#8 PBE algorithms and allow them
5834 to be specified on the command line for the pkcs8 and pkcs12 utilities.
5835 Update documentation.
5838 *) Support for ASN1 "NULL" type. This could be handled before by using
5839 ASN1_TYPE but there wasn't any function that would try to read a NULL
5840 and produce an error if it couldn't. For compatibility we also have
5841 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
5842 don't allocate anything because they don't need to.
5845 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
5847 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
5849 *) Rebuild of the memory allocation routines used by OpenSSL code and
5850 possibly others as well. The purpose is to make an interface that
5851 provide hooks so anyone can build a separate set of allocation and
5852 deallocation routines to be used by OpenSSL, for example memory
5853 pool implementations, or something else, which was previously hard
5854 since Malloc(), Realloc() and Free() were defined as macros having
5855 the values malloc, realloc and free, respectively (except for Win32
5856 compilations). The same is provided for memory debugging code.
5857 OpenSSL already comes with functionality to find memory leaks, but
5858 this gives people a chance to debug other memory problems.
5860 With these changes, a new set of functions and macros have appeared:
5862 CRYPTO_set_mem_debug_functions() [F]
5863 CRYPTO_get_mem_debug_functions() [F]
5864 CRYPTO_dbg_set_options() [F]
5865 CRYPTO_dbg_get_options() [F]
5866 CRYPTO_malloc_debug_init() [M]
5868 The memory debug functions are NULL by default, unless the library
5869 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
5870 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
5871 gives the standard debugging functions that come with OpenSSL) or
5872 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
5873 provided by the library user) must be used. When the standard
5874 debugging functions are used, CRYPTO_dbg_set_options can be used to
5875 request additional information:
5876 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
5877 the CRYPTO_MDEBUG_xxx macro when compiling the library.
5879 Also, things like CRYPTO_set_mem_functions will always give the
5880 expected result (the new set of functions is used for allocation
5881 and deallocation) at all times, regardless of platform and compiler
5884 To finish it up, some functions that were never use in any other
5885 way than through macros have a new API and new semantic:
5888 CRYPTO_dbg_realloc()
5891 All macros of value have retained their old syntax.
5892 [Richard Levitte and Bodo Moeller]
5894 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
5895 ordering of SMIMECapabilities wasn't in "strength order" and there
5896 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
5900 *) Some ASN1 types with illegal zero length encoding (INTEGER,
5901 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
5902 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
5904 *) Merge in my S/MIME library for OpenSSL. This provides a simple
5905 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
5906 functionality to handle multipart/signed properly) and a utility
5907 called 'smime' to call all this stuff. This is based on code I
5908 originally wrote for Celo who have kindly allowed it to be
5909 included in OpenSSL.
5912 *) Add variants des_set_key_checked and des_set_key_unchecked of
5913 des_set_key (aka des_key_sched). Global variable des_check_key
5914 decides which of these is called by des_set_key; this way
5915 des_check_key behaves as it always did, but applications and
5916 the library itself, which was buggy for des_check_key == 1,
5917 have a cleaner way to pick the version they need.
5920 *) New function PKCS12_newpass() which changes the password of a
5924 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
5925 dynamic mix. In both cases the ids can be used as an index into the
5926 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
5927 functions so they accept a list of the field values and the
5928 application doesn't need to directly manipulate the X509_TRUST
5932 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
5936 *) Modify the way the V3 extension code looks up extensions. This now
5937 works in a similar way to the object code: we have some "standard"
5938 extensions in a static table which is searched with OBJ_bsearch()
5939 and the application can add dynamic ones if needed. The file
5940 crypto/x509v3/ext_dat.h now has the info: this file needs to be
5941 updated whenever a new extension is added to the core code and kept
5942 in ext_nid order. There is a simple program 'tabtest.c' which checks
5943 this. New extensions are not added too often so this file can readily
5944 be maintained manually.
5946 There are two big advantages in doing things this way. The extensions
5947 can be looked up immediately and no longer need to be "added" using
5948 X509V3_add_standard_extensions(): this function now does nothing.
5949 [Side note: I get *lots* of email saying the extension code doesn't
5950 work because people forget to call this function]
5951 Also no dynamic allocation is done unless new extensions are added:
5952 so if we don't add custom extensions there is no need to call
5953 X509V3_EXT_cleanup().
5956 *) Modify enc utility's salting as follows: make salting the default. Add a
5957 magic header, so unsalted files fail gracefully instead of just decrypting
5958 to garbage. This is because not salting is a big security hole, so people
5959 should be discouraged from doing it.
5962 *) Fixes and enhancements to the 'x509' utility. It allowed a message
5963 digest to be passed on the command line but it only used this
5964 parameter when signing a certificate. Modified so all relevant
5965 operations are affected by the digest parameter including the
5966 -fingerprint and -x509toreq options. Also -x509toreq choked if a
5967 DSA key was used because it didn't fix the digest.
5970 *) Initial certificate chain verify code. Currently tests the untrusted
5971 certificates for consistency with the verify purpose (which is set
5972 when the X509_STORE_CTX structure is set up) and checks the pathlength.
5974 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
5975 this is because it will reject chains with invalid extensions whereas
5976 every previous version of OpenSSL and SSLeay made no checks at all.
5978 Trust code: checks the root CA for the relevant trust settings. Trust
5979 settings have an initial value consistent with the verify purpose: e.g.
5980 if the verify purpose is for SSL client use it expects the CA to be
5981 trusted for SSL client use. However the default value can be changed to
5982 permit custom trust settings: one example of this would be to only trust
5983 certificates from a specific "secure" set of CAs.
5985 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
5986 which should be used for version portability: especially since the
5987 verify structure is likely to change more often now.
5989 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
5990 to set them. If not set then assume SSL clients will verify SSL servers
5993 Two new options to the verify program: -untrusted allows a set of
5994 untrusted certificates to be passed in and -purpose which sets the
5995 intended purpose of the certificate. If a purpose is set then the
5996 new chain verify code is used to check extension consistency.
5999 *) Support for the authority information access extension.
6002 *) Modify RSA and DSA PEM read routines to transparently handle
6003 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
6004 public keys in a format compatible with certificate
6005 SubjectPublicKeyInfo structures. Unfortunately there were already
6006 functions called *_PublicKey_* which used various odd formats so
6007 these are retained for compatibility: however the DSA variants were
6008 never in a public release so they have been deleted. Changed dsa/rsa
6009 utilities to handle the new format: note no releases ever handled public
6010 keys so we should be OK.
6012 The primary motivation for this change is to avoid the same fiasco
6013 that dogs private keys: there are several incompatible private key
6014 formats some of which are standard and some OpenSSL specific and
6015 require various evil hacks to allow partial transparent handling and
6016 even then it doesn't work with DER formats. Given the option anything
6017 other than PKCS#8 should be dumped: but the other formats have to
6018 stay in the name of compatibility.
6020 With public keys and the benefit of hindsight one standard format
6021 is used which works with EVP_PKEY, RSA or DSA structures: though
6022 it clearly returns an error if you try to read the wrong kind of key.
6024 Added a -pubkey option to the 'x509' utility to output the public key.
6025 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
6026 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
6027 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
6028 that do the same as the EVP_PKEY_assign_*() except they up the
6029 reference count of the added key (they don't "swallow" the
6033 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
6034 CRLs would fail if the file contained no certificates or no CRLs:
6035 added a new function to read in both types and return the number
6036 read: this means that if none are read it will be an error. The
6037 DER versions of the certificate and CRL reader would always fail
6038 because it isn't possible to mix certificates and CRLs in DER format
6039 without choking one or the other routine. Changed this to just read
6040 a certificate: this is the best we can do. Also modified the code
6041 in apps/verify.c to take notice of return codes: it was previously
6042 attempting to read in certificates from NULL pointers and ignoring
6043 any errors: this is one reason why the cert and CRL reader seemed
6044 to work. It doesn't check return codes from the default certificate
6045 routines: these may well fail if the certificates aren't installed.
6048 *) Code to support otherName option in GeneralName.
6051 *) First update to verify code. Change the verify utility
6052 so it warns if it is passed a self signed certificate:
6053 for consistency with the normal behaviour. X509_verify
6054 has been modified to it will now verify a self signed
6055 certificate if *exactly* the same certificate appears
6056 in the store: it was previously impossible to trust a
6057 single self signed certificate. This means that:
6058 openssl verify ss.pem
6059 now gives a warning about a self signed certificate but
6060 openssl verify -CAfile ss.pem ss.pem
6064 *) For servers, store verify_result in SSL_SESSION data structure
6065 (and add it to external session representation).
6066 This is needed when client certificate verifications fails,
6067 but an application-provided verification callback (set by
6068 SSL_CTX_set_cert_verify_callback) allows accepting the session
6069 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
6070 but returns 1): When the session is reused, we have to set
6071 ssl->verify_result to the appropriate error code to avoid
6073 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
6075 *) Fix a bug in the new PKCS#7 code: it didn't consider the
6076 case in PKCS7_dataInit() where the signed PKCS7 structure
6077 didn't contain any existing data because it was being created.
6078 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
6080 *) Add a salt to the key derivation routines in enc.c. This
6081 forms the first 8 bytes of the encrypted file. Also add a
6082 -S option to allow a salt to be input on the command line.
6085 *) New function X509_cmp(). Oddly enough there wasn't a function
6086 to compare two certificates. We do this by working out the SHA1
6087 hash and comparing that. X509_cmp() will be needed by the trust
6091 *) SSL_get1_session() is like SSL_get_session(), but increments
6092 the reference count in the SSL_SESSION returned.
6093 [Geoff Thorpe <geoff@eu.c2.net>]
6095 *) Fix for 'req': it was adding a null to request attributes.
6096 Also change the X509_LOOKUP and X509_INFO code to handle
6097 certificate auxiliary information.
6100 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
6104 *) Add the possibility to add extra information to the memory leak
6105 detecting output, to form tracebacks, showing from where each
6106 allocation was originated: CRYPTO_push_info("constant string") adds
6107 the string plus current file name and line number to a per-thread
6108 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
6109 is like calling CYRPTO_pop_info() until the stack is empty.
6110 Also updated memory leak detection code to be multi-thread-safe.
6113 *) Add options -text and -noout to pkcs7 utility and delete the
6114 encryption options which never did anything. Update docs.
6117 *) Add options to some of the utilities to allow the pass phrase
6118 to be included on either the command line (not recommended on
6119 OSes like Unix) or read from the environment. Update the
6120 manpages and fix a few bugs.
6123 *) Add a few manpages for some of the openssl commands.
6126 *) Fix the -revoke option in ca. It was freeing up memory twice,
6127 leaking and not finding already revoked certificates.
6130 *) Extensive changes to support certificate auxiliary information.
6131 This involves the use of X509_CERT_AUX structure and X509_AUX
6132 functions. An X509_AUX function such as PEM_read_X509_AUX()
6133 can still read in a certificate file in the usual way but it
6134 will also read in any additional "auxiliary information". By
6135 doing things this way a fair degree of compatibility can be
6136 retained: existing certificates can have this information added
6137 using the new 'x509' options.
6139 Current auxiliary information includes an "alias" and some trust
6140 settings. The trust settings will ultimately be used in enhanced
6141 certificate chain verification routines: currently a certificate
6142 can only be trusted if it is self signed and then it is trusted
6146 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
6147 The problem was that one of the replacement routines had not been working
6148 since SSLeay releases. For now the offending routine has been replaced
6149 with non-optimised assembler. Even so, this now gives around 95%
6150 performance improvement for 1024 bit RSA signs.
6153 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
6154 handling. Most clients have the effective key size in bits equal to
6155 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
6156 A few however don't do this and instead use the size of the decrypted key
6157 to determine the RC2 key length and the AlgorithmIdentifier to determine
6158 the effective key length. In this case the effective key length can still
6159 be 40 bits but the key length can be 168 bits for example. This is fixed
6160 by manually forcing an RC2 key into the EVP_PKEY structure because the
6161 EVP code can't currently handle unusual RC2 key sizes: it always assumes
6162 the key length and effective key length are equal.
6165 *) Add a bunch of functions that should simplify the creation of
6166 X509_NAME structures. Now you should be able to do:
6167 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
6168 and have it automatically work out the correct field type and fill in
6169 the structures. The more adventurous can try:
6170 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
6171 and it will (hopefully) work out the correct multibyte encoding.
6174 *) Change the 'req' utility to use the new field handling and multibyte
6175 copy routines. Before the DN field creation was handled in an ad hoc
6176 way in req, ca, and x509 which was rather broken and didn't support
6177 BMPStrings or UTF8Strings. Since some software doesn't implement
6178 BMPStrings or UTF8Strings yet, they can be enabled using the config file
6179 using the dirstring_type option. See the new comment in the default
6180 openssl.cnf for more info.
6183 *) Make crypto/rand/md_rand.c more robust:
6184 - Assure unique random numbers after fork().
6185 - Make sure that concurrent threads access the global counter and
6186 md serializably so that we never lose entropy in them
6187 or use exactly the same state in multiple threads.
6188 Access to the large state is not always serializable because
6189 the additional locking could be a performance killer, and
6190 md should be large enough anyway.
6193 *) New file apps/app_rand.c with commonly needed functionality
6194 for handling the random seed file.
6196 Use the random seed file in some applications that previously did not:
6198 dsaparam -genkey (which also ignored its '-rand' option),
6201 x509 (when signing).
6202 Except on systems with /dev/urandom, it is crucial to have a random
6203 seed file at least for key creation, DSA signing, and for DH exchanges;
6204 for RSA signatures we could do without one.
6206 gendh and gendsa (unlike genrsa) used to read only the first byte
6207 of each file listed in the '-rand' option. The function as previously
6208 found in genrsa is now in app_rand.c and is used by all programs
6209 that support '-rand'.
6212 *) In RAND_write_file, use mode 0600 for creating files;
6213 don't just chmod when it may be too late.
6216 *) Report an error from X509_STORE_load_locations
6217 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
6220 *) New function ASN1_mbstring_copy() this copies a string in either
6221 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
6222 into an ASN1_STRING type. A mask of permissible types is passed
6223 and it chooses the "minimal" type to use or an error if not type
6227 *) Add function equivalents to the various macros in asn1.h. The old
6228 macros are retained with an M_ prefix. Code inside the library can
6229 use the M_ macros. External code (including the openssl utility)
6230 should *NOT* in order to be "shared library friendly".
6233 *) Add various functions that can check a certificate's extensions
6234 to see if it usable for various purposes such as SSL client,
6235 server or S/MIME and CAs of these types. This is currently
6236 VERY EXPERIMENTAL but will ultimately be used for certificate chain
6237 verification. Also added a -purpose flag to x509 utility to
6238 print out all the purposes.
6241 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
6245 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
6246 for, obtain and decode and extension and obtain its critical flag.
6247 This allows all the necessary extension code to be handled in a
6248 single function call.
6251 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
6252 platforms. See crypto/rc4/rc4_enc.c for further details.
6255 *) New -noout option to asn1parse. This causes no output to be produced
6256 its main use is when combined with -strparse and -out to extract data
6257 from a file (which may not be in ASN.1 format).
6260 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
6261 when producing the local key id.
6262 [Richard Levitte <levitte@stacken.kth.se>]
6264 *) New option -dhparam in s_server. This allows a DH parameter file to be
6265 stated explicitly. If it is not stated then it tries the first server
6266 certificate file. The previous behaviour hard coded the filename
6270 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
6271 a public key to be input or output. For example:
6272 openssl rsa -in key.pem -pubout -out pubkey.pem
6273 Also added necessary DSA public key functions to handle this.
6276 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
6277 in the message. This was handled by allowing
6278 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
6279 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
6281 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
6282 to the end of the strings whereas this didn't. This would cause problems
6283 if strings read with d2i_ASN1_bytes() were later modified.
6284 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
6286 *) Fix for base64 decode bug. When a base64 bio reads only one line of
6287 data and it contains EOF it will end up returning an error. This is
6288 caused by input 46 bytes long. The cause is due to the way base64
6289 BIOs find the start of base64 encoded data. They do this by trying a
6290 trial decode on each line until they find one that works. When they
6291 do a flag is set and it starts again knowing it can pass all the
6292 data directly through the decoder. Unfortunately it doesn't reset
6293 the context it uses. This means that if EOF is reached an attempt
6294 is made to pass two EOFs through the context and this causes the
6295 resulting error. This can also cause other problems as well. As is
6296 usual with these problems it takes *ages* to find and the fix is
6297 trivial: move one line.
6298 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
6300 *) Ugly workaround to get s_client and s_server working under Windows. The
6301 old code wouldn't work because it needed to select() on sockets and the
6302 tty (for keypresses and to see if data could be written). Win32 only
6303 supports select() on sockets so we select() with a 1s timeout on the
6304 sockets and then see if any characters are waiting to be read, if none
6305 are present then we retry, we also assume we can always write data to
6306 the tty. This isn't nice because the code then blocks until we've
6307 received a complete line of data and it is effectively polling the
6308 keyboard at 1s intervals: however it's quite a bit better than not
6309 working at all :-) A dedicated Windows application might handle this
6310 with an event loop for example.
6313 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
6314 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
6315 will be called when RSA_sign() and RSA_verify() are used. This is useful
6316 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
6317 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
6318 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
6319 This necessitated the support of an extra signature type NID_md5_sha1
6320 for SSL signatures and modifications to the SSL library to use it instead
6321 of calling RSA_public_decrypt() and RSA_private_encrypt().
6324 *) Add new -verify -CAfile and -CApath options to the crl program, these
6325 will lookup a CRL issuers certificate and verify the signature in a
6326 similar way to the verify program. Tidy up the crl program so it
6327 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
6328 less strict. It will now permit CRL extensions even if it is not
6329 a V2 CRL: this will allow it to tolerate some broken CRLs.
6332 *) Initialize all non-automatic variables each time one of the openssl
6333 sub-programs is started (this is necessary as they may be started
6334 multiple times from the "OpenSSL>" prompt).
6335 [Lennart Bang, Bodo Moeller]
6337 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
6338 removing all other RSA functionality (this is what NO_RSA does). This
6339 is so (for example) those in the US can disable those operations covered
6340 by the RSA patent while allowing storage and parsing of RSA keys and RSA
6344 *) Non-copying interface to BIO pairs.
6345 (still largely untested)
6348 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
6349 ASCII string. This was handled independently in various places before.
6352 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
6353 UTF8 strings a character at a time.
6356 *) Use client_version from client hello to select the protocol
6357 (s23_srvr.c) and for RSA client key exchange verification
6358 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
6361 *) Add various utility functions to handle SPKACs, these were previously
6362 handled by poking round in the structure internals. Added new function
6363 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
6364 print, verify and generate SPKACs. Based on an original idea from
6365 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
6368 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
6371 *) Allow the config file extension section to be overwritten on the
6372 command line. Based on an original idea from Massimiliano Pala
6373 <madwolf@comune.modena.it>. The new option is called -extensions
6374 and can be applied to ca, req and x509. Also -reqexts to override
6375 the request extensions in req and -crlexts to override the crl extensions
6379 *) Add new feature to the SPKAC handling in ca. Now you can include
6380 the same field multiple times by preceding it by "XXXX." for example:
6383 this is the same syntax as used in the req config file.
6386 *) Allow certificate extensions to be added to certificate requests. These
6387 are specified in a 'req_extensions' option of the req section of the
6388 config file. They can be printed out with the -text option to req but
6389 are otherwise ignored at present.
6392 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
6393 data read consists of only the final block it would not decrypted because
6394 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
6395 A misplaced 'break' also meant the decrypted final block might not be
6396 copied until the next read.
6399 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
6400 a few extra parameters to the DH structure: these will be useful if
6401 for example we want the value of 'q' or implement X9.42 DH.
6404 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
6405 provides hooks that allow the default DSA functions or functions on a
6406 "per key" basis to be replaced. This allows hardware acceleration and
6407 hardware key storage to be handled without major modification to the
6408 library. Also added low level modexp hooks and CRYPTO_EX structure and
6409 associated functions.
6412 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
6413 as "read only": it can't be written to and the buffer it points to will
6414 not be freed. Reading from a read only BIO is much more efficient than
6415 a normal memory BIO. This was added because there are several times when
6416 an area of memory needs to be read from a BIO. The previous method was
6417 to create a memory BIO and write the data to it, this results in two
6418 copies of the data and an O(n^2) reading algorithm. There is a new
6419 function BIO_new_mem_buf() which creates a read only memory BIO from
6420 an area of memory. Also modified the PKCS#7 routines to use read only
6424 *) Bugfix: ssl23_get_client_hello did not work properly when called in
6425 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
6426 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
6427 but a retry condition occured while trying to read the rest.
6430 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
6431 NID_pkcs7_encrypted by default: this was wrong since this should almost
6432 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
6433 the encrypted data type: this is a more sensible place to put it and it
6434 allows the PKCS#12 code to be tidied up that duplicated this
6438 *) Changed obj_dat.pl script so it takes its input and output files on
6439 the command line. This should avoid shell escape redirection problems
6443 *) Initial support for certificate extension requests, these are included
6444 in things like Xenroll certificate requests. Included functions to allow
6445 extensions to be obtained and added.
6448 *) -crlf option to s_client and s_server for sending newlines as
6449 CRLF (as required by many protocols).
6452 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
6454 *) Install libRSAglue.a when OpenSSL is built with RSAref.
6455 [Ralf S. Engelschall]
6457 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
6458 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
6460 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
6464 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
6465 DH parameters/keys (q is lost during that conversion, but the resulting
6466 DH parameters contain its length).
6468 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
6469 much faster than DH_generate_parameters (which creates parameters
6470 where p = 2*q + 1), and also the smaller q makes DH computations
6471 much more efficient (160-bit exponentiation instead of 1024-bit
6472 exponentiation); so this provides a convenient way to support DHE
6473 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
6474 utter importance to use
6475 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
6477 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
6478 when such DH parameters are used, because otherwise small subgroup
6479 attacks may become possible!
6482 *) Avoid memory leak in i2d_DHparams.
6485 *) Allow the -k option to be used more than once in the enc program:
6486 this allows the same encrypted message to be read by multiple recipients.
6489 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
6490 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
6491 it will always use the numerical form of the OID, even if it has a short
6495 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
6496 method only got called if p,q,dmp1,dmq1,iqmp components were present,
6497 otherwise bn_mod_exp was called. In the case of hardware keys for example
6498 no private key components need be present and it might store extra data
6499 in the RSA structure, which cannot be accessed from bn_mod_exp.
6500 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
6501 private key operations.
6504 *) Added support for SPARC Linux.
6507 *) pem_password_cb function type incompatibly changed from
6508 typedef int pem_password_cb(char *buf, int size, int rwflag);
6510 ....(char *buf, int size, int rwflag, void *userdata);
6511 so that applications can pass data to their callbacks:
6512 The PEM[_ASN1]_{read,write}... functions and macros now take an
6513 additional void * argument, which is just handed through whenever
6514 the password callback is called.
6515 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
6517 New function SSL_CTX_set_default_passwd_cb_userdata.
6519 Compatibility note: As many C implementations push function arguments
6520 onto the stack in reverse order, the new library version is likely to
6521 interoperate with programs that have been compiled with the old
6522 pem_password_cb definition (PEM_whatever takes some data that
6523 happens to be on the stack as its last argument, and the callback
6524 just ignores this garbage); but there is no guarantee whatsoever that
6527 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
6528 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
6529 problems not only on Windows, but also on some Unix platforms.
6530 To avoid problematic command lines, these definitions are now in an
6531 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
6532 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
6535 *) MIPS III/IV assembler module is reimplemented.
6538 *) More DES library cleanups: remove references to srand/rand and
6539 delete an unused file.
6542 *) Add support for the the free Netwide assembler (NASM) under Win32,
6543 since not many people have MASM (ml) and it can be hard to obtain.
6544 This is currently experimental but it seems to work OK and pass all
6545 the tests. Check out INSTALL.W32 for info.
6548 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
6549 without temporary keys kept an extra copy of the server key,
6550 and connections with temporary keys did not free everything in case
6554 *) New function RSA_check_key and new openssl rsa option -check
6555 for verifying the consistency of RSA keys.
6556 [Ulf Moeller, Bodo Moeller]
6558 *) Various changes to make Win32 compile work:
6559 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
6560 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
6561 comparison" warnings.
6562 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
6565 *) Add a debugging option to PKCS#5 v2 key generation function: when
6566 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
6567 derived keys are printed to stderr.
6570 *) Copy the flags in ASN1_STRING_dup().
6571 [Roman E. Pavlov <pre@mo.msk.ru>]
6573 *) The x509 application mishandled signing requests containing DSA
6574 keys when the signing key was also DSA and the parameters didn't match.
6576 It was supposed to omit the parameters when they matched the signing key:
6577 the verifying software was then supposed to automatically use the CA's
6578 parameters if they were absent from the end user certificate.
6580 Omitting parameters is no longer recommended. The test was also
6581 the wrong way round! This was probably due to unusual behaviour in
6582 EVP_cmp_parameters() which returns 1 if the parameters match.
6583 This meant that parameters were omitted when they *didn't* match and
6584 the certificate was useless. Certificates signed with 'ca' didn't have
6586 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
6588 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
6589 The interface is as follows:
6590 Applications can use
6591 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
6592 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
6593 "off" is now the default.
6594 The library internally uses
6595 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
6596 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
6597 to disable memory-checking temporarily.
6599 Some inconsistent states that previously were possible (and were
6600 even the default) are now avoided.
6602 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
6603 with each memory chunk allocated; this is occasionally more helpful
6604 than just having a counter.
6606 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
6608 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
6612 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
6613 which largely parallels "options", but is for changing API behaviour,
6614 whereas "options" are about protocol behaviour.
6615 Initial "mode" flags are:
6617 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
6618 a single record has been written.
6619 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
6620 retries use the same buffer location.
6621 (But all of the contents must be
6625 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
6628 *) Fix problems with no-hmac etc.
6629 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
6631 *) New functions RSA_get_default_method(), RSA_set_method() and
6632 RSA_get_method(). These allows replacement of RSA_METHODs without having
6633 to mess around with the internals of an RSA structure.
6636 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
6637 Also really enable memory leak checks in openssl.c and in some
6639 [Chad C. Mulligan, Bodo Moeller]
6641 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
6642 up the length of negative integers. This has now been simplified to just
6643 store the length when it is first determined and use it later, rather
6644 than trying to keep track of where data is copied and updating it to
6646 [Steve Henson, reported by Brien Wheeler
6647 <bwheeler@authentica-security.com>]
6649 *) Add a new function PKCS7_signatureVerify. This allows the verification
6650 of a PKCS#7 signature but with the signing certificate passed to the
6651 function itself. This contrasts with PKCS7_dataVerify which assumes the
6652 certificate is present in the PKCS#7 structure. This isn't always the
6653 case: certificates can be omitted from a PKCS#7 structure and be
6654 distributed by "out of band" means (such as a certificate database).
6657 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
6658 function prototypes in pem.h, also change util/mkdef.pl to add the
6659 necessary function names.
6662 *) mk1mf.pl (used by Windows builds) did not properly read the
6663 options set by Configure in the top level Makefile, and Configure
6664 was not even able to write more than one option correctly.
6665 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
6668 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
6669 file to be loaded from a BIO or FILE pointer. The BIO version will
6670 for example allow memory BIOs to contain config info.
6673 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
6674 Whoever hopes to achieve shared-library compatibility across versions
6675 must use this, not the compile-time macro.
6676 (Exercise 0.9.4: Which is the minimum library version required by
6678 Note: All this applies only to multi-threaded programs, others don't
6682 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
6683 through a BIO pair triggered the default case, i.e.
6684 SSLerr(...,SSL_R_UNKNOWN_STATE).
6687 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
6688 can use the SSL library even if none of the specific BIOs is
6692 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
6693 for the encoded length.
6694 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
6696 *) Add initial documentation of the X509V3 functions.
6699 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
6700 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
6701 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
6702 secure PKCS#8 private key format with a high iteration count.
6705 *) Fix determination of Perl interpreter: A perl or perl5
6706 _directory_ in $PATH was also accepted as the interpreter.
6707 [Ralf S. Engelschall]
6709 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
6710 wrong with it but it was very old and did things like calling
6711 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
6715 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
6716 to use the new extension code.
6719 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
6720 with macros. This should make it easier to change their form, add extra
6721 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
6725 *) Add to configuration table a new entry that can specify an alternative
6726 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
6727 according to Mark Crispin <MRC@Panda.COM>.
6731 *) DES CBC did not update the IV. Weird.
6734 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
6735 Changing the behaviour of the former might break existing programs --
6736 where IV updating is needed, des_ncbc_encrypt can be used.
6739 *) When bntest is run from "make test" it drives bc to check its
6740 calculations, as well as internally checking them. If an internal check
6741 fails, it needs to cause bc to give a non-zero result or make test carries
6742 on without noticing the failure. Fixed.
6745 *) DES library cleanups.
6748 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
6749 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
6750 ciphers. NOTE: although the key derivation function has been verified
6751 against some published test vectors it has not been extensively tested
6752 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
6756 *) Instead of "mkdir -p", which is not fully portable, use new
6757 Perl script "util/mkdir-p.pl".
6760 *) Rewrite the way password based encryption (PBE) is handled. It used to
6761 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
6762 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
6763 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
6764 the 'parameter' field of the AlgorithmIdentifier is passed to the
6765 underlying key generation function so it must do its own ASN1 parsing.
6766 This has also changed the EVP_PBE_CipherInit() function which now has a
6767 'parameter' argument instead of literal salt and iteration count values
6768 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
6771 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
6772 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
6773 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
6774 KEY" because this clashed with PKCS#8 unencrypted string. Since this
6775 value was just used as a "magic string" and not used directly its
6776 value doesn't matter.
6779 *) Introduce some semblance of const correctness to BN. Shame C doesn't
6783 *) "linux-sparc64" configuration (ultrapenguin).
6784 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
6785 "linux-sparc" configuration.
6786 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
6788 *) config now generates no-xxx options for missing ciphers.
6791 *) Support the EBCDIC character set (work in progress).
6792 File ebcdic.c not yet included because it has a different license.
6793 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
6795 *) Support BS2000/OSD-POSIX.
6796 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
6798 *) Make callbacks for key generation use void * instead of char *.
6801 *) Make S/MIME samples compile (not yet tested).
6804 *) Additional typesafe stacks.
6807 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
6811 Changes between 0.9.3 and 0.9.3a [29 May 1999]
6813 *) New configuration variant "sco5-gcc".
6815 *) Updated some demos.
6816 [Sean O Riordain, Wade Scholine]
6818 *) Add missing BIO_free at exit of pkcs12 application.
6821 *) Fix memory leak in conf.c.
6824 *) Updates for Win32 to assembler version of MD5.
6827 *) Set #! path to perl in apps/der_chop to where we found it
6828 instead of using a fixed path.
6831 *) SHA library changes for irix64-mips4-cc.
6834 *) Improvements for VMS support.
6838 Changes between 0.9.2b and 0.9.3 [24 May 1999]
6840 *) Bignum library bug fix. IRIX 6 passes "make test" now!
6841 This also avoids the problems with SC4.2 and unpatched SC5.
6842 [Andy Polyakov <appro@fy.chalmers.se>]
6844 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
6845 These are required because of the typesafe stack would otherwise break
6846 existing code. If old code used a structure member which used to be STACK
6847 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
6848 sk_num or sk_value it would produce an error because the num, data members
6849 are not present in STACK_OF. Now it just produces a warning. sk_set
6850 replaces the old method of assigning a value to sk_value
6851 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
6852 that does this will no longer work (and should use sk_set instead) but
6853 this could be regarded as a "questionable" behaviour anyway.
6856 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
6857 correctly handle encrypted S/MIME data.
6860 *) Change type of various DES function arguments from des_cblock
6861 (which means, in function argument declarations, pointer to char)
6862 to des_cblock * (meaning pointer to array with 8 char elements),
6863 which allows the compiler to do more typechecking; it was like
6864 that back in SSLeay, but with lots of ugly casts.
6866 Introduce new type const_des_cblock.
6869 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
6870 problems: find RecipientInfo structure that matches recipient certificate
6871 and initialise the ASN1 structures properly based on passed cipher.
6874 *) Belatedly make the BN tests actually check the results.
6877 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
6878 to and from BNs: it was completely broken. New compilation option
6879 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
6880 key elements as negative integers.
6883 *) Reorganize and speed up MD5.
6884 [Andy Polyakov <appro@fy.chalmers.se>]
6887 [Richard Levitte <richard@levitte.org>]
6889 *) New option -out to asn1parse to allow the parsed structure to be
6890 output to a file. This is most useful when combined with the -strparse
6891 option to examine the output of things like OCTET STRINGS.
6894 *) Make SSL library a little more fool-proof by not requiring any longer
6895 that SSL_set_{accept,connect}_state be called before
6896 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
6897 in many applications because usually everything *appeared* to work as
6898 intended anyway -- now it really works as intended).
6901 *) Move openssl.cnf out of lib/.
6904 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
6905 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
6906 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
6907 [Ralf S. Engelschall]
6909 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
6910 handle PKCS#7 enveloped data properly.
6911 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
6913 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
6914 copying pointers. The cert_st handling is changed by this in
6915 various ways (and thus what used to be known as ctx->default_cert
6916 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
6917 any longer when s->cert does not give us what we need).
6918 ssl_cert_instantiate becomes obsolete by this change.
6919 As soon as we've got the new code right (possibly it already is?),
6920 we have solved a couple of bugs of the earlier code where s->cert
6921 was used as if it could not have been shared with other SSL structures.
6923 Note that using the SSL API in certain dirty ways now will result
6924 in different behaviour than observed with earlier library versions:
6925 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
6926 does not influence s as it used to.
6928 In order to clean up things more thoroughly, inside SSL_SESSION
6929 we don't use CERT any longer, but a new structure SESS_CERT
6930 that holds per-session data (if available); currently, this is
6931 the peer's certificate chain and, for clients, the server's certificate
6932 and temporary key. CERT holds only those values that can have
6933 meaningful defaults in an SSL_CTX.
6936 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
6937 from the internal representation. Various PKCS#7 fixes: remove some
6938 evil casts and set the enc_dig_alg field properly based on the signing
6942 *) Allow PKCS#12 password to be set from the command line or the
6943 environment. Let 'ca' get its config file name from the environment
6944 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
6948 *) Allow certificate policies extension to use an IA5STRING for the
6949 organization field. This is contrary to the PKIX definition but
6950 VeriSign uses it and IE5 only recognises this form. Document 'x509'
6954 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
6955 without disallowing inline assembler and the like for non-pedantic builds.
6958 *) Support Borland C++ builder.
6959 [Janez Jere <jj@void.si>, modified by Ulf Möller]
6964 *) SHA-1 cleanups and performance enhancements.
6965 [Andy Polyakov <appro@fy.chalmers.se>]
6967 *) Sparc v8plus assembler for the bignum library.
6968 [Andy Polyakov <appro@fy.chalmers.se>]
6970 *) Accept any -xxx and +xxx compiler options in Configure.
6973 *) Update HPUX configuration.
6976 *) Add missing sk_<type>_unshift() function to safestack.h
6977 [Ralf S. Engelschall]
6979 *) New function SSL_CTX_use_certificate_chain_file that sets the
6980 "extra_cert"s in addition to the certificate. (This makes sense
6981 only for "PEM" format files, as chains as a whole are not
6985 *) Support verify_depth from the SSL API.
6986 x509_vfy.c had what can be considered an off-by-one-error:
6987 Its depth (which was not part of the external interface)
6988 was actually counting the number of certificates in a chain;
6989 now it really counts the depth.
6992 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
6993 instead of X509err, which often resulted in confusing error
6994 messages since the error codes are not globally unique
6995 (e.g. an alleged error in ssl3_accept when a certificate
6996 didn't match the private key).
6998 *) New function SSL_CTX_set_session_id_context that allows to set a default
6999 value (so that you don't need SSL_set_session_id_context for each
7000 connection using the SSL_CTX).
7003 *) OAEP decoding bug fix.
7006 *) Support INSTALL_PREFIX for package builders, as proposed by
7010 *) New Configure options "threads" and "no-threads". For systems
7011 where the proper compiler options are known (currently Solaris
7012 and Linux), "threads" is the default.
7015 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
7018 *) Install various scripts to $(OPENSSLDIR)/misc, not to
7019 $(INSTALLTOP)/bin -- they shouldn't clutter directories
7020 such as /usr/local/bin.
7023 *) "make linux-shared" to build shared libraries.
7024 [Niels Poppe <niels@netbox.org>]
7026 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
7029 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
7030 extension adding in x509 utility.
7033 *) Remove NOPROTO sections and error code comments.
7036 *) Partial rewrite of the DEF file generator to now parse the ANSI
7040 *) New Configure options --prefix=DIR and --openssldir=DIR.
7043 *) Complete rewrite of the error code script(s). It is all now handled
7044 by one script at the top level which handles error code gathering,
7045 header rewriting and C source file generation. It should be much better
7046 than the old method: it now uses a modified version of Ulf's parser to
7047 read the ANSI prototypes in all header files (thus the old K&R definitions
7048 aren't needed for error creation any more) and do a better job of
7049 translating function codes into names. The old 'ASN1 error code imbedded
7050 in a comment' is no longer necessary and it doesn't use .err files which
7051 have now been deleted. Also the error code call doesn't have to appear all
7052 on one line (which resulted in some large lines...).
7055 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
7058 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
7059 0 (which usually indicates a closed connection), but continue reading.
7062 *) Fix some race conditions.
7065 *) Add support for CRL distribution points extension. Add Certificate
7066 Policies and CRL distribution points documentation.
7069 *) Move the autogenerated header file parts to crypto/opensslconf.h.
7072 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
7073 8 of keying material. Merlin has also confirmed interop with this fix
7074 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
7075 [Merlin Hughes <merlin@baltimore.ie>]
7077 *) Fix lots of warnings.
7078 [Richard Levitte <levitte@stacken.kth.se>]
7080 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
7081 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
7082 [Richard Levitte <levitte@stacken.kth.se>]
7084 *) Fix problems with sizeof(long) == 8.
7085 [Andy Polyakov <appro@fy.chalmers.se>]
7087 *) Change functions to ANSI C.
7090 *) Fix typos in error codes.
7091 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
7093 *) Remove defunct assembler files from Configure.
7096 *) SPARC v8 assembler BIGNUM implementation.
7097 [Andy Polyakov <appro@fy.chalmers.se>]
7099 *) Support for Certificate Policies extension: both print and set.
7100 Various additions to support the r2i method this uses.
7103 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
7104 return a const string when you are expecting an allocated buffer.
7107 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
7108 types DirectoryString and DisplayText.
7111 *) Add code to allow r2i extensions to access the configuration database,
7112 add an LHASH database driver and add several ctx helper functions.
7115 *) Fix an evil bug in bn_expand2() which caused various BN functions to
7116 fail when they extended the size of a BIGNUM.
7119 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
7120 support typesafe stack.
7123 *) Fix typo in SSL_[gs]et_options().
7124 [Nils Frostberg <nils@medcom.se>]
7126 *) Delete various functions and files that belonged to the (now obsolete)
7127 old X509V3 handling code.
7130 *) New Configure option "rsaref".
7133 *) Don't auto-generate pem.h.
7136 *) Introduce type-safe ASN.1 SETs.
7139 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
7140 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
7142 *) Introduce type-safe STACKs. This will almost certainly break lots of code
7143 that links with OpenSSL (well at least cause lots of warnings), but fear
7144 not: the conversion is trivial, and it eliminates loads of evil casts. A
7145 few STACKed things have been converted already. Feel free to convert more.
7146 In the fullness of time, I'll do away with the STACK type altogether.
7149 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
7150 specified in <certfile> by updating the entry in the index.txt file.
7151 This way one no longer has to edit the index.txt file manually for
7152 revoking a certificate. The -revoke option does the gory details now.
7153 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
7155 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
7156 `-text' option at all and this way the `-noout -text' combination was
7157 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
7158 [Ralf S. Engelschall]
7160 *) Make sure a corresponding plain text error message exists for the
7161 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
7162 verify callback function determined that a certificate was revoked.
7163 [Ralf S. Engelschall]
7165 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
7166 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
7167 all available cipers including rc5, which was forgotten until now.
7168 In order to let the testing shell script know which algorithms
7169 are available, a new (up to now undocumented) command
7170 "openssl list-cipher-commands" is used.
7173 *) Bugfix: s_client occasionally would sleep in select() when
7174 it should have checked SSL_pending() first.
7177 *) New functions DSA_do_sign and DSA_do_verify to provide access to
7178 the raw DSA values prior to ASN.1 encoding.
7181 *) Tweaks to Configure
7182 [Niels Poppe <niels@netbox.org>]
7184 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
7188 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
7191 *) New config option to avoid instructions that are illegal on the 80386.
7192 The default code is faster, but requires at least a 486.
7195 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
7196 SSL2_SERVER_VERSION (not used at all) macros, which are now the
7197 same as SSL2_VERSION anyway.
7200 *) New "-showcerts" option for s_client.
7203 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
7204 application. Various cleanups and fixes.
7207 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
7208 modify error routines to work internally. Add error codes and PBE init
7209 to library startup routines.
7212 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
7213 packing functions to asn1 and evp. Changed function names and error
7214 codes along the way.
7217 *) PKCS12 integration: and so it begins... First of several patches to
7218 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
7219 objects to objects.h
7222 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
7223 and display support for Thawte strong extranet extension.
7226 *) Add LinuxPPC support.
7227 [Jeff Dubrule <igor@pobox.org>]
7229 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
7230 bn_div_words in alpha.s.
7231 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
7233 *) Make sure the RSA OAEP test is skipped under -DRSAref because
7234 OAEP isn't supported when OpenSSL is built with RSAref.
7235 [Ulf Moeller <ulf@fitug.de>]
7237 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
7238 so they no longer are missing under -DNOPROTO.
7239 [Soren S. Jorvang <soren@t.dk>]
7242 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
7244 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
7245 doesn't work when the session is reused. Coming soon!
7248 *) Fix a security hole, that allows sessions to be reused in the wrong
7249 context thus bypassing client cert protection! All software that uses
7250 client certs and session caches in multiple contexts NEEDS PATCHING to
7251 allow session reuse! A fuller solution is in the works.
7252 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
7254 *) Some more source tree cleanups (removed obsolete files
7255 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
7256 permission on "config" script to be executable) and a fix for the INSTALL
7258 [Ulf Moeller <ulf@fitug.de>]
7260 *) Remove some legacy and erroneous uses of malloc, free instead of
7262 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
7264 *) Make rsa_oaep_test return non-zero on error.
7265 [Ulf Moeller <ulf@fitug.de>]
7267 *) Add support for native Solaris shared libraries. Configure
7268 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
7269 if someone would make that last step automatic.
7270 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
7272 *) ctx_size was not built with the right compiler during "make links". Fixed.
7275 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
7276 except NULL ciphers". This means the default cipher list will no longer
7277 enable NULL ciphers. They need to be specifically enabled e.g. with
7278 the string "DEFAULT:eNULL".
7281 *) Fix to RSA private encryption routines: if p < q then it would
7282 occasionally produce an invalid result. This will only happen with
7283 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
7286 *) Be less restrictive and allow also `perl util/perlpath.pl
7287 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
7288 because this way one can also use an interpreter named `perl5' (which is
7289 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
7290 installed as `perl').
7291 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
7293 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
7294 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
7296 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
7297 advapi32.lib to Win32 build and change the pem test comparision
7298 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
7299 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
7300 and crypto/des/ede_cbcm_enc.c.
7303 *) DES quad checksum was broken on big-endian architectures. Fixed.
7306 *) Comment out two functions in bio.h that aren't implemented. Fix up the
7307 Win32 test batch file so it (might) work again. The Win32 test batch file
7308 is horrible: I feel ill....
7311 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
7312 in e_os.h. Audit of header files to check ANSI and non ANSI
7313 sections: 10 functions were absent from non ANSI section and not exported
7314 from Windows DLLs. Fixed up libeay.num for new functions.
7317 *) Make `openssl version' output lines consistent.
7318 [Ralf S. Engelschall]
7320 *) Fix Win32 symbol export lists for BIO functions: Added
7321 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
7322 to ms/libeay{16,32}.def.
7323 [Ralf S. Engelschall]
7325 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
7326 fine under Unix and passes some trivial tests I've now added. But the
7327 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
7328 added to make sure no one expects that this stuff really works in the
7329 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
7330 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
7332 [Ralf S. Engelschall]
7334 *) Fix the generation of two part addresses in perl.
7335 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
7337 *) Add config entry for Linux on MIPS.
7338 [John Tobey <jtobey@channel1.com>]
7340 *) Make links whenever Configure is run, unless we are on Windoze.
7343 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
7344 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
7348 *) Add a useful kludge to allow package maintainers to specify compiler and
7349 other platforms details on the command line without having to patch the
7350 Configure script everytime: One now can use ``perl Configure
7351 <id>:<details>'', i.e. platform ids are allowed to have details appended
7352 to them (seperated by colons). This is treated as there would be a static
7353 pre-configured entry in Configure's %table under key <id> with value
7354 <details> and ``perl Configure <id>'' is called. So, when you want to
7355 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
7356 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
7357 now, which overrides the FreeBSD-elf entry on-the-fly.
7358 [Ralf S. Engelschall]
7360 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
7363 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
7364 on the `perl Configure ...' command line. This way one can compile
7365 OpenSSL libraries with Position Independent Code (PIC) which is needed
7366 for linking it into DSOs.
7367 [Ralf S. Engelschall]
7369 *) Remarkably, export ciphers were totally broken and no-one had noticed!
7373 *) Cleaned up the LICENSE document: The official contact for any license
7374 questions now is the OpenSSL core team under openssl-core@openssl.org.
7375 And add a paragraph about the dual-license situation to make sure people
7376 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
7377 to the OpenSSL toolkit.
7378 [Ralf S. Engelschall]
7380 *) General source tree makefile cleanups: Made `making xxx in yyy...'
7381 display consistent in the source tree and replaced `/bin/rm' by `rm'.
7382 Additonally cleaned up the `make links' target: Remove unnecessary
7383 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
7384 to speed processing and no longer clutter the display with confusing
7385 stuff. Instead only the actually done links are displayed.
7386 [Ralf S. Engelschall]
7388 *) Permit null encryption ciphersuites, used for authentication only. It used
7389 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
7390 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
7394 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
7395 signed attributes when verifying signatures (this would break them),
7396 the detached data encoding was wrong and public keys obtained using
7397 X509_get_pubkey() weren't freed.
7400 *) Add text documentation for the BUFFER functions. Also added a work around
7401 to a Win95 console bug. This was triggered by the password read stuff: the
7402 last character typed gets carried over to the next fread(). If you were
7403 generating a new cert request using 'req' for example then the last
7404 character of the passphrase would be CR which would then enter the first
7408 *) Added the new `Includes OpenSSL Cryptography Software' button as
7409 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
7410 button and can be used by applications based on OpenSSL to show the
7411 relationship to the OpenSSL project.
7412 [Ralf S. Engelschall]
7414 *) Remove confusing variables in function signatures in files
7415 ssl/ssl_lib.c and ssl/ssl.h.
7416 [Lennart Bong <lob@kulthea.stacken.kth.se>]
7418 *) Don't install bss_file.c under PREFIX/include/
7419 [Lennart Bong <lob@kulthea.stacken.kth.se>]
7421 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
7422 functions that return function pointers and has support for NT specific
7423 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
7424 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
7425 unsigned to signed types: this was killing the Win32 compile.
7428 *) Add new certificate file to stack functions,
7429 SSL_add_dir_cert_subjects_to_stack() and
7430 SSL_add_file_cert_subjects_to_stack(). These largely supplant
7431 SSL_load_client_CA_file(), and can be used to add multiple certs easily
7432 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
7433 This means that Apache-SSL and similar packages don't have to mess around
7434 to add as many CAs as they want to the preferred list.
7437 *) Experiment with doxygen documentation. Currently only partially applied to
7439 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
7440 openssl.doxy as the configuration file.
7443 *) Get rid of remaining C++-style comments which strict C compilers hate.
7444 [Ralf S. Engelschall, pointed out by Carlos Amengual]
7446 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
7447 compiled in by default: it has problems with large keys.
7450 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
7451 DH private keys and/or callback functions which directly correspond to
7452 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
7453 is needed for applications which have to configure certificates on a
7454 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
7456 For the RSA certificate situation is makes no difference, but
7457 for the DSA certificate situation this fixes the "no shared cipher"
7458 problem where the OpenSSL cipher selection procedure failed because the
7459 temporary keys were not overtaken from the context and the API provided
7460 no way to reconfigure them.
7461 The new functions now let applications reconfigure the stuff and they
7462 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
7463 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
7464 non-public-API function ssl_cert_instantiate() is used as a helper
7465 function and also to reduce code redundancy inside ssl_rsa.c.
7466 [Ralf S. Engelschall]
7468 *) Move s_server -dcert and -dkey options out of the undocumented feature
7469 area because they are useful for the DSA situation and should be
7470 recognized by the users.
7471 [Ralf S. Engelschall]
7473 *) Fix the cipher decision scheme for export ciphers: the export bits are
7474 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
7475 SSL_EXP_MASK. So, the original variable has to be used instead of the
7476 already masked variable.
7477 [Richard Levitte <levitte@stacken.kth.se>]
7479 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
7480 [Richard Levitte <levitte@stacken.kth.se>]
7482 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
7483 from `int' to `unsigned int' because it's a length and initialized by
7484 EVP_DigestFinal() which expects an `unsigned int *'.
7485 [Richard Levitte <levitte@stacken.kth.se>]
7487 *) Don't hard-code path to Perl interpreter on shebang line of Configure
7488 script. Instead use the usual Shell->Perl transition trick.
7489 [Ralf S. Engelschall]
7491 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
7492 (in addition to RSA certificates) to match the behaviour of `openssl dsa
7493 -noout -modulus' as it's already the case for `openssl rsa -noout
7494 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
7495 currently the public key is printed (a decision which was already done by
7496 `openssl dsa -modulus' in the past) which serves a similar purpose.
7497 Additionally the NO_RSA no longer completely removes the whole -modulus
7498 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
7500 [Ralf S. Engelschall]
7502 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
7503 BIO. See the source (crypto/evp/bio_ok.c) for more info.
7504 [Arne Ansper <arne@ats.cyber.ee>]
7506 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
7507 to be added. Now both 'req' and 'ca' can use new objects defined in the
7511 *) Add cool BIO that does syslog (or event log on NT).
7512 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
7514 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
7515 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
7516 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
7517 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
7520 *) Add preliminary config info for new extension code.
7523 *) Make RSA_NO_PADDING really use no padding.
7524 [Ulf Moeller <ulf@fitug.de>]
7526 *) Generate errors when private/public key check is done.
7529 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
7530 for some CRL extensions and new objects added.
7533 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
7534 key usage extension and fuller support for authority key id.
7537 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
7538 padding method for RSA, which is recommended for new applications in PKCS
7539 #1 v2.0 (RFC 2437, October 1998).
7540 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
7541 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
7542 against Bleichbacher's attack on RSA.
7543 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
7546 *) Updates to the new SSL compression code
7547 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
7549 *) Fix so that the version number in the master secret, when passed
7550 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
7551 (because the server will not accept higher), that the version number
7552 is 0x03,0x01, not 0x03,0x00
7553 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
7555 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
7556 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
7557 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
7560 *) Support for RAW extensions where an arbitrary extension can be
7561 created by including its DER encoding. See apps/openssl.cnf for
7565 *) Make sure latest Perl versions don't interpret some generated C array
7566 code as Perl array code in the crypto/err/err_genc.pl script.
7567 [Lars Weber <3weber@informatik.uni-hamburg.de>]
7569 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
7570 not many people have the assembler. Various Win32 compilation fixes and
7571 update to the INSTALL.W32 file with (hopefully) more accurate Win32
7575 *) Modify configure script 'Configure' to automatically create crypto/date.h
7576 file under Win32 and also build pem.h from pem.org. New script
7577 util/mkfiles.pl to create the MINFO file on environments that can't do a
7578 'make files': perl util/mkfiles.pl >MINFO should work.
7581 *) Major rework of DES function declarations, in the pursuit of correctness
7582 and purity. As a result, many evil casts evaporated, and some weirdness,
7583 too. You may find this causes warnings in your code. Zapping your evil
7584 casts will probably fix them. Mostly.
7587 *) Fix for a typo in asn1.h. Bug fix to object creation script
7588 obj_dat.pl. It considered a zero in an object definition to mean
7589 "end of object": none of the objects in objects.h have any zeros
7590 so it wasn't spotted.
7591 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
7593 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
7594 Masking (CBCM). In the absence of test vectors, the best I have been able
7595 to do is check that the decrypt undoes the encrypt, so far. Send me test
7596 vectors if you have them.
7599 *) Correct calculation of key length for export ciphers (too much space was
7600 allocated for null ciphers). This has not been tested!
7603 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
7604 message is now correct (it understands "crypto" and "ssl" on its
7605 command line). There is also now an "update" option. This will update
7606 the util/ssleay.num and util/libeay.num files with any new functions.
7608 perl util/mkdef.pl crypto ssl update
7609 it will update them.
7612 *) Overhauled the Perl interface (perl/*):
7613 - ported BN stuff to OpenSSL's different BN library
7614 - made the perl/ source tree CVS-aware
7615 - renamed the package from SSLeay to OpenSSL (the files still contain
7616 their history because I've copied them in the repository)
7617 - removed obsolete files (the test scripts will be replaced
7618 by better Test::Harness variants in the future)
7619 [Ralf S. Engelschall]
7621 *) First cut for a very conservative source tree cleanup:
7622 1. merge various obsolete readme texts into doc/ssleay.txt
7623 where we collect the old documents and readme texts.
7624 2. remove the first part of files where I'm already sure that we no
7625 longer need them because of three reasons: either they are just temporary
7626 files which were left by Eric or they are preserved original files where
7627 I've verified that the diff is also available in the CVS via "cvs diff
7628 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
7629 the crypto/md/ stuff).
7630 [Ralf S. Engelschall]
7632 *) More extension code. Incomplete support for subject and issuer alt
7633 name, issuer and authority key id. Change the i2v function parameters
7634 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
7635 what that's for :-) Fix to ASN1 macro which messed up
7636 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
7639 *) Preliminary support for ENUMERATED type. This is largely copied from the
7643 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
7644 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
7646 *) Make sure `make rehash' target really finds the `openssl' program.
7647 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
7649 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
7650 like to hear about it if this slows down other processors.
7653 *) Add CygWin32 platform information to Configure script.
7654 [Alan Batie <batie@aahz.jf.intel.com>]
7656 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
7657 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
7659 *) New program nseq to manipulate netscape certificate sequences
7662 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
7666 *) Fixes to BN code. Previously the default was to define BN_RECURSION
7667 but the BN code had some problems that would cause failures when
7668 doing certificate verification and some other functions.
7669 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
7671 *) Add ASN1 and PEM code to support netscape certificate sequences.
7674 *) Add ASN1 and PEM code to support netscape certificate sequences.
7677 *) Add several PKIX and private extended key usage OIDs.
7680 *) Modify the 'ca' program to handle the new extension code. Modify
7681 openssl.cnf for new extension format, add comments.
7684 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
7685 and add a sample to openssl.cnf so req -x509 now adds appropriate
7689 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
7690 error code, add initial support to X509_print() and x509 application.
7693 *) Takes a deep breath and start addding X509 V3 extension support code. Add
7694 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
7695 stuff is currently isolated and isn't even compiled yet.
7698 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
7699 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
7700 Removed the versions check from X509 routines when loading extensions:
7701 this allows certain broken certificates that don't set the version
7702 properly to be processed.
7705 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
7706 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
7707 can still be regenerated with "make depend".
7710 *) Spelling mistake in C version of CAST-128.
7711 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
7713 *) Changes to the error generation code. The perl script err-code.pl
7714 now reads in the old error codes and retains the old numbers, only
7715 adding new ones if necessary. It also only changes the .err files if new
7716 codes are added. The makefiles have been modified to only insert errors
7717 when needed (to avoid needlessly modifying header files). This is done
7718 by only inserting errors if the .err file is newer than the auto generated
7719 C file. To rebuild all the error codes from scratch (the old behaviour)
7720 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
7721 or delete all the .err files.
7724 *) CAST-128 was incorrectly implemented for short keys. The C version has
7725 been fixed, but is untested. The assembler versions are also fixed, but
7726 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
7727 to regenerate it if needed.
7728 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
7729 Hagino <itojun@kame.net>]
7731 *) File was opened incorrectly in randfile.c.
7732 [Ulf Möller <ulf@fitug.de>]
7734 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
7735 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
7736 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
7737 al: it's just almost always a UTCTime. Note this patch adds new error
7738 codes so do a "make errors" if there are problems.
7741 *) Correct Linux 1 recognition in config.
7742 [Ulf Möller <ulf@fitug.de>]
7744 *) Remove pointless MD5 hash when using DSA keys in ca.
7745 [Anonymous <nobody@replay.com>]
7747 *) Generate an error if given an empty string as a cert directory. Also
7748 generate an error if handed NULL (previously returned 0 to indicate an
7749 error, but didn't set one).
7750 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
7752 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
7755 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
7756 parameters. This was causing a warning which killed off the Win32 compile.
7759 *) Remove C++ style comments from crypto/bn/bn_local.h.
7760 [Neil Costigan <neil.costigan@celocom.com>]
7762 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
7763 based on a text string, looking up short and long names and finally
7764 "dot" format. The "dot" format stuff didn't work. Added new function
7765 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
7766 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
7767 OID is not part of the table.
7770 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
7771 X509_LOOKUP_by_alias().
7774 *) Sort openssl functions by name.
7777 *) Get the gendsa program working (hopefully) and add it to app list. Remove
7778 encryption from sample DSA keys (in case anyone is interested the password
7782 *) Make _all_ *_free functions accept a NULL pointer.
7783 [Frans Heymans <fheymans@isaserver.be>]
7785 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
7787 [Anonymous <nobody@replay.com>]
7789 *) s_server should send the CAfile as acceptable CAs, not its own cert.
7790 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
7792 *) Don't blow it for numeric -newkey arguments to apps/req.
7793 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
7795 *) Temp key "for export" tests were wrong in s3_srvr.c.
7796 [Anonymous <nobody@replay.com>]
7798 *) Add prototype for temp key callback functions
7799 SSL_CTX_set_tmp_{rsa,dh}_callback().
7802 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
7803 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
7806 *) X509_name_add_entry() freed the wrong thing after an error.
7807 [Arne Ansper <arne@ats.cyber.ee>]
7809 *) rsa_eay.c would attempt to free a NULL context.
7810 [Arne Ansper <arne@ats.cyber.ee>]
7812 *) BIO_s_socket() had a broken should_retry() on Windoze.
7813 [Arne Ansper <arne@ats.cyber.ee>]
7815 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
7816 [Arne Ansper <arne@ats.cyber.ee>]
7818 *) Make sure the already existing X509_STORE->depth variable is initialized
7819 in X509_STORE_new(), but document the fact that this variable is still
7820 unused in the certificate verification process.
7821 [Ralf S. Engelschall]
7823 *) Fix the various library and apps files to free up pkeys obtained from
7824 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
7827 *) Fix reference counting in X509_PUBKEY_get(). This makes
7828 demos/maurice/example2.c work, amongst others, probably.
7829 [Steve Henson and Ben Laurie]
7831 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
7832 `openssl' and second, the shortcut symlinks for the `openssl <command>'
7833 are no longer created. This way we have a single and consistent command
7834 line interface `openssl <command>', similar to `cvs <command>'.
7835 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
7837 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
7838 BIT STRING wrapper always have zero unused bits.
7841 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
7844 *) Make the top-level INSTALL documentation easier to understand.
7847 *) Makefiles updated to exit if an error occurs in a sub-directory
7848 make (including if user presses ^C) [Paul Sutton]
7850 *) Make Montgomery context stuff explicit in RSA data structure.
7853 *) Fix build order of pem and err to allow for generated pem.h.
7856 *) Fix renumbering bug in X509_NAME_delete_entry().
7859 *) Enhanced the err-ins.pl script so it makes the error library number
7860 global and can add a library name. This is needed for external ASN1 and
7861 other error libraries.
7864 *) Fixed sk_insert which never worked properly.
7867 *) Fix ASN1 macros so they can handle indefinite length construted
7868 EXPLICIT tags. Some non standard certificates use these: they can now
7872 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
7873 into a single doc/ssleay.txt bundle. This way the information is still
7874 preserved but no longer messes up this directory. Now it's new room for
7875 the new set of documenation files.
7876 [Ralf S. Engelschall]
7878 *) SETs were incorrectly DER encoded. This was a major pain, because they
7879 shared code with SEQUENCEs, which aren't coded the same. This means that
7880 almost everything to do with SETs or SEQUENCEs has either changed name or
7881 number of arguments.
7882 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
7884 *) Fix test data to work with the above.
7887 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
7888 was already fixed by Eric for 0.9.1 it seems.
7889 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
7891 *) Autodetect FreeBSD3.
7894 *) Fix various bugs in Configure. This affects the following platforms:
7898 unixware-2.0-pentium
7902 *) Eliminate generated files from CVS. Reorder tests to regenerate files
7903 before they are needed.
7906 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
7910 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
7912 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
7913 changed SSLeay to OpenSSL in version strings.
7914 [Ralf S. Engelschall]
7916 *) Some fixups to the top-level documents.
7919 *) Fixed the nasty bug where rsaref.h was not found under compile-time
7920 because the symlink to include/ was missing.
7921 [Ralf S. Engelschall]
7923 *) Incorporated the popular no-RSA/DSA-only patches
7924 which allow to compile a RSA-free SSLeay.
7925 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
7927 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
7928 when "ssleay" is still not found.
7929 [Ralf S. Engelschall]
7931 *) Added more platforms to Configure: Cray T3E, HPUX 11,
7932 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
7934 *) Updated the README file.
7935 [Ralf S. Engelschall]
7937 *) Added various .cvsignore files in the CVS repository subdirs
7938 to make a "cvs update" really silent.
7939 [Ralf S. Engelschall]
7941 *) Recompiled the error-definition header files and added
7942 missing symbols to the Win32 linker tables.
7943 [Ralf S. Engelschall]
7945 *) Cleaned up the top-level documents;
7946 o new files: CHANGES and LICENSE
7947 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
7948 o merged COPYRIGHT into LICENSE
7949 o removed obsolete TODO file
7950 o renamed MICROSOFT to INSTALL.W32
7951 [Ralf S. Engelschall]
7953 *) Removed dummy files from the 0.9.1b source tree:
7954 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
7955 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

7958 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
7959 [Ralf S. Engelschall]
7961 *) Added various platform portability fixes.
7964 *) The Genesis of the OpenSSL rpject:
7965 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
7966 Young and Tim J. Hudson created while they were working for C2Net until
7968 [The OpenSSL Project]
7971 Changes between 0.9.0b and 0.9.1b [not released]
7973 *) Updated a few CA certificates under certs/
7976 *) Changed some BIGNUM api stuff.
7979 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
7980 DGUX x86, Linux Alpha, etc.
7983 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
7984 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
7988 *) Add -strparse option to asn1pars program which parses nested
7990 [Dr Stephen Henson <shenson@bigfoot.com>]
7992 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
7995 *) DSA fix for "ca" program.
7998 *) Added "-genkey" option to "dsaparam" program.
8001 *) Added RIPE MD160 (rmd160) message digest.
8004 *) Added -a (all) option to "ssleay version" command.
8007 *) Added PLATFORM define which is the id given to Configure.
8010 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
8013 *) Extended the ASN.1 parser routines.
8016 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
8019 *) Added a BN_CTX to the BN library.
8022 *) Fixed the weak key values in DES library
8025 *) Changed API in EVP library for cipher aliases.
8028 *) Added support for RC2/64bit cipher.
8031 *) Converted the lhash library to the crypto/mem.c functions.
8034 *) Added more recognized ASN.1 object ids.
8037 *) Added more RSA padding checks for SSL/TLS.
8040 *) Added BIO proxy/filter functionality.
8043 *) Added extra_certs to SSL_CTX which can be used
8044 send extra CA certificates to the client in the CA cert chain sending
8045 process. It can be configured with SSL_CTX_add_extra_chain_cert().
8048 *) Now Fortezza is denied in the authentication phase because
8049 this is key exchange mechanism is not supported by SSLeay at all.
8052 *) Additional PKCS1 checks.
8055 *) Support the string "TLSv1" for all TLS v1 ciphers.
8058 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
8059 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
8062 *) Fixed a few memory leaks.
8065 *) Fixed various code and comment typos.
8068 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
8069 bytes sent in the client random.
