5 Changes between 0.9.6 and 0.9.7 [xx XXX 2001]
7 OpenSSL 0.9.6a/0.9.6b (bugfix releases, 5 Apr 2001 and 9 July 2001)
8 and OpenSSL 0.9.7 were developed in parallel, based on OpenSSL 0.9.6.
10 Change log entries are tagged as follows:
11 -) applies to 0.9.6a/0.9.6b/0.9.6c only
12 *) applies to 0.9.6a/0.9.6b/0.9.6c and 0.9.7
13 +) applies to 0.9.7 only
15 +) Add some demos for certificate and certificate request creation.
18 +) Make maximum certificate chain size accepted from the peer application
19 settable (SSL*_get/set_max_cert_list()), as proposed by
20 "Douglas E. Engert" <deengert@anl.gov>.
23 +) Add support for shared libraries for Unixware-7 and support including
24 shared libraries for OpenUNIX-8 (Boyd Lynn Gerber <gerberb@zenez.com>).
27 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
28 'wristwatch attack' using huge encoding parameters (cf.
29 James H. Manger's CRYPTO 2001 paper). Note that the
30 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
31 encoding parameters and hence was not vulnerable.
34 +) Add a "destroy" handler to ENGINEs that allows structural cleanup to
35 be done prior to destruction. Use this to unload error strings from
36 ENGINEs that load their own error strings. NB: This adds two new API
37 functions to "get" and "set" this destroy handler in an ENGINE.
40 +) Alter all existing ENGINE implementations (except "openssl" and
41 "openbsd") to dynamically instantiate their own error strings. This
42 makes them more flexible to be built both as statically-linked ENGINEs
43 and self-contained shared-libraries loadable via the "dynamic" ENGINE.
44 Also, add stub code to each that makes building them as self-contained
45 shared-libraries easier (see README.ENGINE).
48 +) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
49 implementations into applications that are completely implemented in
50 self-contained shared-libraries. The "dynamic" ENGINE exposes control
51 commands that can be used to configure what shared-library to load and
52 to control aspects of the way it is handled. Also, made an update to
53 the README.ENGINE file that brings its information up-to-date and
54 provides some information and instructions on the "dynamic" ENGINE
55 (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
59 [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
61 *) Make it possible to unload ranges of ERR strings with a new
62 "ERR_unload_strings" function.
65 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
66 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
67 followed by modular reduction.
68 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
70 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
71 equivalent based on BN_pseudo_rand() instead of BN_rand().
74 +) Add a copy() function to EVP_MD.
77 +) Make EVP_MD routines take a context pointer instead of just the
81 +) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
82 that the digest can only process a single chunk of data
83 (typically because it is provided by a piece of
84 hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
85 is only going to provide a single chunk of data, and hence the
86 framework needn't accumulate the data for oneshot drivers.
89 +) As with "ERR", make it possible to replace the underlying "ex_data"
90 functions. This change also alters the storage and management of global
91 ex_data state - it's now all inside ex_data.c and all "class" code (eg.
92 RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
93 index counters. The API functions that use this state have been changed
94 to take a "class_index" rather than pointers to the class's local STACK
95 and counter, and there is now an API function to dynamically create new
96 classes. This centralisation allows us to (a) plug a lot of the
97 thread-safety problems that existed, and (b) makes it possible to clean
98 up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
99 such data would previously have always leaked in application code and
100 workarounds were in place to make the memory debugging turn a blind eye
101 to it. Application code that doesn't use this new function will still
102 leak as before, but their memory debugging output will announce it now
103 rather than letting it slide.
105 Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
106 induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
107 has a return value to indicate success or failure.
110 +) Make it possible to replace the underlying "ERR" functions such that the
111 global state (2 LHASH tables and 2 locks) is only used by the "default"
112 implementation. This change also adds two functions to "get" and "set"
113 the implementation prior to it being automatically set the first time
114 any other ERR function takes place. Ie. an application can call "get",
115 pass the return value to a module it has just loaded, and that module
116 can call its own "set" function using that value. This means the
117 module's "ERR" operations will use (and modify) the error state in the
118 application and not in its own statically linked copy of OpenSSL code.
121 +) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
122 reference counts. This performs normal REF_PRINT/REF_CHECK macros on
123 the operation, and provides a more encapsulated way for external code
124 (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
125 to use these functions rather than manually incrementing the counts.
127 Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
130 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
131 This function was broken, as the check for a new client hello message
132 to handle SGC did not allow these large messages.
133 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
136 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
139 +) Add EVP test program.
142 +) Add symmetric cipher support to ENGINE. Expect the API to change!
145 +) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
146 X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
147 X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
148 These allow a CRL to be built without having to access X509_CRL fields
149 directly. Modify 'ca' application to use new functions.
152 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
153 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
156 *) Rework the configuration and shared library support for Tru64 Unix.
157 The configuration part makes use of modern compiler features and
158 still retains old compiler behavior for those that run older versions
159 of the OS. The shared library support part includes a variant that
160 uses the RPATH feature, and is available through the special
161 configuration target "alpha-cc-rpath", which will never be selected
163 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
165 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
166 with the same message size as in ssl3_get_certificate_request().
167 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
168 messages might inadvertently be reject as too long.
169 [Petr Lampa <lampa@fee.vutbr.cz>]
171 +) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
172 bug workarounds. Rollback attack detection is a security feature.
173 The problem will only arise on OpenSSL servers when TLSv1 is not
174 available (sslv3_server_method() or SSL_OP_NO_TLSv1).
175 Software authors not wanting to support TLSv1 will have special reasons
176 for their choice and can explicitly enable this option.
177 [Bodo Moeller, Lutz Jaenicke]
179 +) Rationalise EVP so it can be extended: don't include a union of
180 cipher/digest structures, add init/cleanup functions. This also reduces
181 the number of header dependencies.
184 +) Make DES key schedule conform to the usual scheme, as well as
185 correcting its structure. This means that calls to DES functions
186 now have to pass a pointer to a des_key_schedule instead of a
187 plain des_key_schedule (which was actually always a pointer
191 +) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
194 *) Modified SSL library such that the verify_callback that has been set
195 specificly for an SSL object with SSL_set_verify() is actually being
196 used. Before the change, a verify_callback set with this function was
197 ignored and the verify_callback() set in the SSL_CTX at the time of
198 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
199 to allow the necessary settings.
202 +) Initial reduction of linker bloat: the use of some functions, such as
203 PEM causes large amounts of unused functions to be linked in due to
204 poor organisation. For example pem_all.c contains every PEM function
205 which has a knock on effect of linking in large amounts of (unused)
206 ASN1 code. Grouping together similar functions and splitting unrelated
207 functions prevents this.
210 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
211 explicitly to NULL, as at least on Solaris 8 this seems not always to be
212 done automatically (in contradiction to the requirements of the C
213 standard). This made problems when used from OpenSSH.
216 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
217 dh->length and always used
219 BN_rand_range(priv_key, dh->p).
221 BN_rand_range() is not necessary for Diffie-Hellman, and this
222 specific range makes Diffie-Hellman unnecessarily inefficient if
223 dh->length (recommended exponent length) is much smaller than the
224 length of dh->p. We could use BN_rand_range() if the order of
225 the subgroup was stored in the DH structure, but we only have
230 BN_rand(priv_key, l, ...)
232 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
238 RSA_eay_public_encrypt
239 RSA_eay_private_decrypt
240 RSA_eay_private_encrypt (signing)
241 RSA_eay_public_decrypt (signature verification)
243 (default implementations for RSA_public_encrypt,
244 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
245 always reject numbers >= n.
248 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
249 to synchronize access to 'locking_thread'. This is necessary on
250 systems where access to 'locking_thread' (an 'unsigned long'
251 variable) is not atomic.
254 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
255 *before* setting the 'crypto_lock_rand' flag. The previous code had
256 a race condition if 0 is a valid thread ID.
257 [Travis Vitek <vitek@roguewave.com>]
259 +) Cleanup of EVP macros.
262 +) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
266 +) Add initial OCSP responder support to ocsp application. The
267 revocation information is handled using the text based index
268 use by the ca application. The responder can either handle
269 requests generated internally, supplied in files (for example
270 via a CGI script) or using an internal minimal server.
273 +) Add configuration choices to get zlib compression for TLS.
276 +) Changes to Kerberos SSL for RFC 2712 compliance:
277 1. Implemented real KerberosWrapper, instead of just using
278 KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
279 2. Implemented optional authenticator field of KerberosWrapper.
281 Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
282 and authenticator structs; see crypto/krb5/.
284 Generalized Kerberos calls to support multiple Kerberos libraries.
285 [Vern Staats <staatsvr@asc.hpc.mil>,
286 Jeffrey Altman <jaltman@columbia.edu>
289 +) Cause 'openssl speed' to use fully hard-coded DSA keys as it
290 already does with RSA. testdsa.h now has 'priv_key/pub_key'
291 values for each of the key sizes rather than having just
292 parameters (and 'speed' generating keys each time).
295 -) OpenSSL 0.9.6b released [9 July 2001]
297 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
298 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
299 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
300 PRNG state recovery was possible based on the output of
301 one PRNG request appropriately sized to gain knowledge on
302 'md' followed by enough consecutive 1-byte PRNG requests
303 to traverse all of 'state'.
305 1. When updating 'md_local' (the current thread's copy of 'md')
306 during PRNG output generation, hash all of the previous
307 'md_local' value, not just the half used for PRNG output.
309 2. Make the number of bytes from 'state' included into the hash
310 independent from the number of PRNG bytes requested.
312 The first measure alone would be sufficient to avoid
313 Markku-Juhani's attack. (Actually it had never occurred
314 to me that the half of 'md_local' used for chaining was the
315 half from which PRNG output bytes were taken -- I had always
316 assumed that the secret half would be used.) The second
317 measure makes sure that additional data from 'state' is never
318 mixed into 'md_local' in small portions; this heuristically
319 further strengthens the PRNG.
322 +) Speed up EVP routines.

340 *) Fix crypto/bn/asm/mips3.s.
343 *) When only the key is given to "enc", the IV is undefined. Print out
344 an error message in this case.
347 +) Added the OS2-EMX target.
348 ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
350 +) Rewrite apps to use NCONF routines instead of the old CONF. New functions
351 to support NCONF routines in extension code. New function CONF_set_nconf()
352 to allow functions which take an NCONF to also handle the old LHASH
353 structure: this means that the old CONF compatible routines can be
354 retained (in particular wrt extensions) without having to duplicate the
355 code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
358 *) Handle special case when X509_NAME is empty in X509 printing routines.
361 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
362 positive and less than q.
365 +) Enhance the general user interface with mechanisms for inner control
366 and with possibilities to have yes/no kind of prompts.
369 +) Change all calls to low level digest routines in the library and
370 applications to use EVP. Add missing calls to HMAC_cleanup() and
371 don't assume HMAC_CTX can be copied using memcpy().
372 [Verdon Walker <VWalker@novell.com>, Steve Henson]
374 +) Add the possibility to control engines through control names but with
375 arbitrary arguments instead of just a string.
376 Change the key loaders to take a UI_METHOD instead of a callback
377 function pointer. NOTE: this breaks binary compatibility with earlier
378 versions of OpenSSL [engine].
379 Adapt the nCipher code for these new conditions and add a card insertion
383 +) Enhance the general user interface with mechanisms to better support
384 dialog box interfaces, application-defined prompts, the possibility
385 to use defaults (for example default passwords from somewhere else)
386 and interrupts/cancellations.
389 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
390 used: it isn't thread safe and the add_lock_callback should handle
392 [Paul Rose <Paul.Rose@bridge.com>]
394 *) Verify that incoming data obeys the block size in
395 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
398 +) Tidy up PKCS#12 attribute handling. Add support for the CSP name
399 attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
403 [Ulf Möller, Bodo Möller]
405 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
406 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
407 when fixing the server behaviour for backwards-compatible 'client
408 hello' messages. (Note that the attack is impractical against
409 SSL 3.0 and TLS 1.0 anyway because length and version checking
410 means that the probability of guessing a valid ciphertext is
411 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
414 Before 0.9.5, the countermeasure (hide the error by generating a
415 random 'decryption result') did not work properly because
416 ERR_clear_error() was missing, meaning that SSL_get_error() would
417 detect the supposedly ignored error.
419 Both problems are now fixed.
422 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
423 (previously it was 1024).
426 +) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
427 tidy up some unnecessarily weird code in 'sk_new()').
428 [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
430 +) Change the key loading routines for ENGINEs to use the same kind
431 callback (pem_password_cb) as all other routines that need this
435 *) Fix for compatibility mode trust settings: ignore trust settings
436 unless some valid trust or reject settings are present.
439 *) Fix for blowfish EVP: its a variable length cipher.
442 +) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
443 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
444 than this minimum value is recommended.
447 +) New random seeder for OpenVMS, using the system process statistics
448 that are easily reachable.
451 +) Windows apparently can't transparently handle global
452 variables defined in DLLs. Initialisations such as:
454 const ASN1_ITEM *it = &ASN1_INTEGER_it;
456 wont compile. This is used by the any applications that need to
457 declare their own ASN1 modules. This was fixed by adding the option
458 EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
459 needed for static libraries under Win32.
462 +) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
463 setting of purpose and trust fields. New X509_STORE trust and
464 purpose functions and tidy up setting in other SSL functions.
467 +) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
468 structure. These are inherited by X509_STORE_CTX when it is
469 initialised. This allows various defaults to be set in the
470 X509_STORE structure (such as flags for CRL checking and custom
471 purpose or trust settings) for functions which only use X509_STORE_CTX
472 internally such as S/MIME.
474 Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
475 trust settings if they are not set in X509_STORE. This allows X509_STORE
476 purposes and trust (in S/MIME for example) to override any set by default.
478 Add command line options for CRL checking to smime, s_client and s_server
482 +) Initial CRL based revocation checking. If the CRL checking flag(s)
483 are set then the CRL is looked up in the X509_STORE structure and
484 its validity and signature checked, then if the certificate is found
485 in the CRL the verify fails with a revoked error.
487 Various new CRL related callbacks added to X509_STORE_CTX structure.
489 Command line options added to 'verify' application to support this.
491 This needs some additional work, such as being able to handle multiple
492 CRLs with different times, extension based lookup (rather than just
493 by subject name) and ultimately more complete V2 CRL extension
497 +) Add a general user interface API (crypto/ui/). This is designed
498 to replace things like des_read_password and friends (backward
499 compatibility functions using this new API are provided).
500 The purpose is to remove prompting functions from the DES code
501 section as well as provide for prompting through dialog boxes in
502 a window system and the like.
505 *) Fix various bugs related to DSA S/MIME verification. Handle missing
506 parameters in DSA public key structures and return an error in the
507 DSA routines if parameters are absent.
510 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
511 in the current directory if neither $RANDFILE nor $HOME was set.
512 RAND_file_name() in 0.9.6a returned NULL in this case. This has
513 caused some confusion to Windows users who haven't defined $HOME.
514 Thus RAND_file_name() is changed again: e_os.h can define a
515 DEFAULT_HOME, which will be used if $HOME is not set.
516 For Windows, we use "C:"; on other platforms, we still require
517 environment variables.
519 +) Add "ex_data" support to ENGINE so implementations can add state at a
520 per-structure level rather than having to store it globally.
523 +) Make it possible for ENGINE structures to be copied when retrieved by
524 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
525 This causes the "original" ENGINE structure to act like a template,
526 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
527 operational state can be localised to each ENGINE structure, despite the
528 fact they all share the same "methods". New ENGINE structures returned in
529 this case have no functional references and the return value is the single
530 structural reference. This matches the single structural reference returned
531 by ENGINE_by_id() normally, when it is incremented on the pre-existing
535 +) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
536 needs to match any other type at all we need to manually clear the
540 +) Changes to the "openssl engine" utility to include;
541 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
542 about an ENGINE's available control commands.
543 - executing control commands from command line arguments using the
544 '-pre' and '-post' switches. '-post' is only used if '-t' is
545 specified and the ENGINE is successfully initialised. The syntax for
546 the individual commands are colon-separated, for example;
547 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
550 +) New dynamic control command support for ENGINEs. ENGINEs can now
551 declare their own commands (numbers), names (strings), descriptions,
552 and input types for run-time discovery by calling applications. A
553 subset of these commands are implicitly classed as "executable"
554 depending on their input type, and only these can be invoked through
555 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
556 can be based on user input, config files, etc). The distinction is
557 that "executable" commands cannot return anything other than a boolean
558 result and can only support numeric or string input, whereas some
559 discoverable commands may only be for direct use through
560 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
561 pointers, or other custom uses. The "executable" commands are to
562 support parameterisations of ENGINE behaviour that can be
563 unambiguously defined by ENGINEs and used consistently across any
564 OpenSSL-based application. Commands have been added to all the
565 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
566 control over shared-library paths without source code alterations.
569 +) Changed all ENGINE implementations to dynamically allocate their
570 ENGINEs rather than declaring them statically. Apart from this being
571 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
572 this also allows the implementations to compile without using the
573 internal engine_int.h header.
576 +) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
577 'const' value. Any code that should be able to modify a RAND_METHOD
578 should already have non-const pointers to it (ie. they should only
579 modify their own ones).
582 +) Made a variety of little tweaks to the ENGINE code.
583 - "atalla" and "ubsec" string definitions were moved from header files
584 to C code. "nuron" string definitions were placed in variables
585 rather than hard-coded - allowing parameterisation of these values
586 later on via ctrl() commands.
587 - Removed unused "#if 0"'d code.
588 - Fixed engine list iteration code so it uses ENGINE_free() to release
589 structural references.
590 - Constified the RAND_METHOD element of ENGINE structures.
591 - Constified various get/set functions as appropriate and added
592 missing functions (including a catch-all ENGINE_cpy that duplicates
593 all ENGINE values onto a new ENGINE except reference counts/state).
594 - Removed NULL parameter checks in get/set functions. Setting a method
595 or function to NULL is a way of cancelling out a previously set
596 value. Passing a NULL ENGINE parameter is just plain stupid anyway
597 and doesn't justify the extra error symbols and code.
598 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
599 flags from engine_int.h to engine.h.
600 - Changed prototypes for ENGINE handler functions (init(), finish(),
601 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
604 *) Move 'if (!initialized) RAND_poll()' into regions protected by
605 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
606 having multiple threads call RAND_poll() concurrently.
609 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
610 combination of a flag and a thread ID variable.
611 Otherwise while one thread is in ssleay_rand_bytes (which sets the
612 flag), *other* threads can enter ssleay_add_bytes without obeying
613 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
614 that they do not hold after the first thread unsets add_do_not_lock).
617 +) Implement binary inversion algorithm for BN_mod_inverse in addition
618 to the algorithm using long division. The binary algorithm can be
619 used only if the modulus is odd. On 32-bit systems, it is faster
620 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
621 roughly 5-15% for 256-bit moduli), so we use it only for moduli
622 up to 450 bits. In 64-bit environments, the binary algorithm
623 appears to be advantageous for much longer moduli; here we use it
624 for moduli up to 2048 bits.
627 *) Change bctest again: '-x' expressions are not available in all
631 -) OpenSSL 0.9.6a released [5 Apr 2001]
633 *) Fix a couple of memory leaks in PKCS7_dataDecode()
634 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
636 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
637 the default extension for executables, if any. Also, make the perl
638 scripts that use symlink() to test if it really exists and use "cp"
639 if it doesn't. All this made OpenSSL compilable and installable in
643 +) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
644 could not support the combine flag in choice fields.
647 -) Fix for asn1_GetSequence() for indefinite length constructed data.
648 If SEQUENCE is length is indefinite just set c->slen to the total
649 amount of data available.
650 [Steve Henson, reported by shige@FreeBSD.org]
651 [This change does not apply to 0.9.7.]
653 *) Change bctest to avoid here-documents inside command substitution
654 (workaround for FreeBSD /bin/sh bug).
655 For compatibility with Ultrix, avoid shell functions (introduced
656 in the bctest version that searches along $PATH).
659 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
660 with des_encrypt() defined on some operating systems, like Solaris
664 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
665 On the Importance of Eliminating Errors in Cryptographic
666 Computations, J. Cryptology 14 (2001) 2, 101-119,
667 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
670 *) MIPS assembler BIGNUM division bug fix.
673 *) Disabled incorrect Alpha assembler code.
676 -) Fix PKCS#7 decode routines so they correctly update the length
677 after reading an EOC for the EXPLICIT tag.
679 [This change does not apply to 0.9.7.]
681 *) Fix bug in PKCS#12 key generation routines. This was triggered
682 if a 3DES key was generated with a 0 initial byte. Include
683 PKCS12_BROKEN_KEYGEN compilation option to retain the old
684 (but broken) behaviour.
687 *) Enhance bctest to search for a working bc along $PATH and print
689 [Tim Rice <tim@multitalents.net> via Richard Levitte]
691 +) Add a 'copy_extensions' option to the 'ca' utility. This copies
692 extensions from a certificate request to the certificate.
695 +) Allow multiple 'certopt' and 'nameopt' options to be separated
696 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
697 file: this allows the display of the certificate about to be
698 signed to be customised, to allow certain fields to be included
699 or excluded and extension details. The old system didn't display
700 multicharacter strings properly, omitted fields not in the policy
701 and couldn't display additional details such as extensions.
704 *) Fix memory leaks in err.c: free err_data string if necessary;
705 don't write to the wrong index in ERR_set_error_data.
708 +) Function EC_POINTs_mul for simultaneous scalar multiplication
709 of an arbitrary number of elliptic curve points, optionally
710 including the generator defined for the EC_GROUP.
711 EC_POINT_mul is a simple wrapper function for the typical case
712 that the point list has just one item (besides the optional
716 +) First EC_METHODs for curves over GF(p):
718 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
719 operations and provides various method functions that can also
720 operate with faster implementations of modular arithmetic.
722 EC_GFp_mont_method() reuses most functions that are part of
723 EC_GFp_simple_method, but uses Montgomery arithmetic.
725 [Bodo Moeller; point addition and point doubling
726 implementation directly derived from source code provided by
727 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
729 +) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
732 Curves are EC_GROUP objects (with an optional group generator)
733 based on EC_METHODs that are built into the library.
735 Points are EC_POINT objects based on EC_GROUP objects.
737 Most of the framework would be able to handle curves over arbitrary
738 finite fields, but as there are no obvious types for fields other
739 than GF(p), some functions are limited to that for now.
742 +) Add the -HTTP option to s_server. It is similar to -WWW, but requires
743 that the file contains a complete HTTP response.
746 +) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
747 change the def and num file printf format specifier from "%-40sXXX"
748 to "%-39s XXX". The latter will always guarantee a space after the
749 field while the former will cause them to run together if the field
750 is 40 of more characters long.
753 +) Constify the cipher and digest 'method' functions and structures
754 and modify related functions to take constant EVP_MD and EVP_CIPHER
758 *) Implement ssl23_peek (analogous to ssl23_read), which previously
762 *) Replace rdtsc with _emit statements for VC++ version 5.
763 [Jeremy Cooper <jeremy@baymoo.org>]
765 +) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
766 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
769 +) Modify EVP_Digest*() routines so they now return values. Although the
770 internal software routines can never fail additional hardware versions
774 +) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
776 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
777 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
780 ERR_R_NESTED_ASN1_ERROR
782 ERR_R_MISSING_ASN1_EOS
783 were 4 .. 9, conflicting with
784 ERR_LIB_RSA (= ERR_R_RSA_LIB)
786 ERR_LIB_PEM (= ERR_R_PEM_LIB).
787 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
789 Add new error code 'ERR_R_INTERNAL_ERROR'.
792 +) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
796 +) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
797 sets the subject name for a new request or supersedes the
798 subject name in a given request. Formats that can be parsed are
799 'CN=Some Name, OU=myOU, C=IT'
801 'CN=Some Name/OU=myOU/C=IT'.
803 Add options '-batch' and '-verbose' to 'openssl req'.
804 [Massimiliano Pala <madwolf@hackmasters.net>]
806 *) Make it possible to reuse SSLv2 sessions.
809 +) Introduce the possibility to access global variables through
810 functions on platform were that's the best way to handle exporting
811 global variables in shared libraries. To enable this functionality,
812 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
813 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
814 is normally done by Configure or something similar).
816 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
817 in the source file (foo.c) like this:
819 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
820 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
822 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
823 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
825 OPENSSL_DECLARE_GLOBAL(int,foo);
826 #define foo OPENSSL_GLOBAL_REF(foo)
827 OPENSSL_DECLARE_GLOBAL(double,bar);
828 #define bar OPENSSL_GLOBAL_REF(bar)
830 The #defines are very important, and therefore so is including the
831 header file everywhere where the defined globals are used.
833 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
834 of ASN.1 items, but that structure is a bit different.
836 The largest change is in util/mkdef.pl which has been enhanced with
837 better and easier to understand logic to choose which symbols should
838 go into the Windows .def files as well as a number of fixes and code
839 cleanup (among others, algorithm keywords are now sorted
840 lexicographically to avoid constant rewrites).
843 *) In copy_email() check for >= 0 as a return value for
844 X509_NAME_get_index_by_NID() since 0 is a valid index.
845 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
847 +) In BN_div() keep a copy of the sign of 'num' before writing the
848 result to 'rm' because if rm==num the value will be overwritten
849 and produce the wrong result if 'num' is negative: this caused
850 problems with BN_mod() and BN_nnmod().
853 +) Function OCSP_request_verify(). This checks the signature on an
854 OCSP request and verifies the signer certificate. The signer
855 certificate is just checked for a generic purpose and OCSP request
859 +) Add OCSP_check_validity() function to check the validity of OCSP
860 responses. OCSP responses are prepared in real time and may only
861 be a few seconds old. Simply checking that the current time lies
862 between thisUpdate and nextUpdate max reject otherwise valid responses
863 caused by either OCSP responder or client clock inaccuracy. Instead
864 we allow thisUpdate and nextUpdate to fall within a certain period of
865 the current time. The age of the response can also optionally be
866 checked. Two new options -validity_period and -status_age added to
870 +) If signature or public key algorithm is unrecognized print out its
871 OID rather that just UNKNOWN.
874 *) Avoid coredump with unsupported or invalid public keys by checking if
875 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
876 PKCS7_verify() fails with non detached data.
879 +) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
880 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
881 ID to be generated from the issuer certificate alone which can then be
882 passed to OCSP_id_issuer_cmp().
885 +) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
886 ASN1 modules to export functions returning ASN1_ITEM pointers
887 instead of the ASN1_ITEM structures themselves. This adds several
888 new macros which allow the underlying ASN1 function/structure to
889 be accessed transparently. As a result code should not use ASN1_ITEM
890 references directly (such as &X509_it) but instead use the relevant
891 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
892 use of the new ASN1 code on platforms where exporting structures
893 is problematical (for example in shared libraries) but exporting
894 functions returning pointers to structures is not.
897 +) Add support for overriding the generation of SSL/TLS session IDs.
898 These callbacks can be registered either in an SSL_CTX or per SSL.
899 The purpose of this is to allow applications to control, if they wish,
900 the arbitrary values chosen for use as session IDs, particularly as it
901 can be useful for session caching in multiple-server environments. A
902 command-line switch for testing this (and any client code that wishes
903 to use such a feature) has been added to "s_server".
904 [Geoff Thorpe, Lutz Jaenicke]
906 +) Modify mkdef.pl to recognise and parse preprocessor conditionals
907 of the form '#if defined(...) || defined(...) || ...' and
908 '#if !defined(...) && !defined(...) && ...'. This also avoids
909 the growing number of special cases it was previously handling.
912 *) Don't use getenv in library functions when run as setuid/setgid.
913 New function OPENSSL_issetugid().
916 +) Make all configuration macros available for application by making
917 sure they are available in opensslconf.h, by giving them names starting
918 with "OPENSSL_" to avoid conflicts with other packages and by making
919 sure e_os2.h will cover all platform-specific cases together with
921 Additionally, it is now possible to define configuration/platform-
922 specific names (called "system identities"). In the C code, these
923 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
924 macro with the name beginning with "OPENSSL_SYS_", which is determined
925 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
929 +) New option -set_serial to 'req' and 'x509' this allows the serial
930 number to use to be specified on the command line. Previously self
931 signed certificates were hard coded with serial number 0 and the
932 CA options of 'x509' had to use a serial number in a file which was
936 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
937 due to incorrect handling of multi-threading:
939 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
941 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
943 3. Count how many times MemCheck_off() has been called so that
944 nested use can be treated correctly. This also avoids
945 inband-signalling in the previous code (which relied on the
946 assumption that thread ID 0 is impossible).
949 +) New options to 'ca' utility to support V2 CRL entry extensions.
950 Currently CRL reason, invalidity date and hold instruction are
951 supported. Add new CRL extensions to V3 code and some new objects.
954 *) Add "-rand" option also to s_client and s_server.
957 +) New function EVP_CIPHER_CTX_set_padding() this is used to
958 disable standard block padding (aka PKCS#5 padding) in the EVP
959 API, which was previously mandatory. This means that the data is
960 not padded in any way and so the total length much be a multiple
961 of the block size, otherwise an error occurs.
964 +) Initial (incomplete) OCSP SSL support.
967 *) Fix CPU detection on Irix 6.x.
968 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
969 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
971 +) New function OCSP_parse_url(). This splits up a URL into its host,
972 port and path components: primarily to parse OCSP URLs. New -url
973 option to ocsp utility.
976 +) New nonce behavior. The return value of OCSP_check_nonce() now
977 reflects the various checks performed. Applications can decide
978 whether to tolerate certain situations such as an absent nonce
979 in a response when one was present in a request: the ocsp application
980 just prints out a warning. New function OCSP_add1_basic_nonce()
981 this is to allow responders to include a nonce in a response even if
982 the request is nonce-less.
985 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
988 [This change does not apply to 0.9.7.]
990 *) Use the cached encoding of an X509_NAME structure rather than
991 copying it. This is apparently the reason for the libsafe "errors"
992 but the code is actually correct.
995 +) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
996 skipped when using openssl x509 multiple times on a single input file,
997 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
1000 +) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
1001 set string type: to handle setting ASN1_TIME structures. Fix ca
1002 utility to correctly initialize revocation date of CRLs.
1005 +) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
1006 the clients preferred ciphersuites and rather use its own preferences.
1007 Should help to work around M$ SGC (Server Gated Cryptography) bug in
1008 Internet Explorer by ensuring unchanged hash method during stepup.
1009 (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
1012 +) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
1013 to aes and add a new 'exist' option to print out symbols that don't
1017 +) Additional options to ocsp utility to allow flags to be set and
1018 additional certificates supplied.
1021 +) Add the option -VAfile to 'openssl ocsp', so the user can give the
1022 OCSP client a number of certificate to only verify the response
1026 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
1027 Bleichenbacher's DSA attack.
1028 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
1029 to be set and top=0 forces the highest bit to be set; top=-1 is new
1030 and leaves the highest bit random.
1031 [Ulf Moeller, Bodo Moeller]
1033 +) Update Rijndael code to version 3.0 and change EVP AES ciphers to
1034 handle the new API. Currently only ECB, CBC modes supported. Add new
1035 AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
1036 for TLS" draft-ietf-tls-ciphersuite-03.txt.
1037 [Ben Laurie, Steve Henson]
1039 *) In the NCONF_...-based implementations for CONF_... queries
1040 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
1041 a temporary CONF structure with the data component set to NULL
1042 (which gives segmentation faults in lh_retrieve).
1043 Instead, use NULL for the CONF pointer in CONF_get_string and
1044 CONF_get_number (which may use environment variables) and directly
1045 return NULL from CONF_get_section.
1048 *) Fix potential buffer overrun for EBCDIC.
1051 +) New function OCSP_copy_nonce() to copy nonce value (if present) from
1052 request to response.
1055 +) Functions for OCSP responders. OCSP_request_onereq_count(),
1056 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
1057 extract information from a certificate request. OCSP_response_create()
1058 creates a response and optionally adds a basic response structure.
1059 OCSP_basic_add1_status() adds a complete single response to a basic
1060 response and returns the OCSP_SINGLERESP structure just added (to allow
1061 extensions to be included for example). OCSP_basic_add1_cert() adds a
1062 certificate to a basic response and OCSP_basic_sign() signs a basic
1063 response with various flags. New helper functions ASN1_TIME_check()
1064 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
1065 (converts ASN1_TIME to GeneralizedTime).
1068 +) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
1069 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
1070 structure from a certificate. X509_pubkey_digest() digests the public_key
1071 contents: this is used in various key identifiers.
1074 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
1075 keyUsage if basicConstraints absent for a CA.
1078 *) Make SMIME_write_PKCS7() write mail header values with a format that
1079 is more generally accepted (no spaces before the semicolon), since
1080 some programs can't parse those values properly otherwise. Also make
1081 sure BIO's that break lines after each write do not create invalid
1085 +) Make sk_sort() tolerate a NULL argument.
1086 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
1088 +) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
1089 passed by the function are trusted implicitly. If any of them signed the
1090 response then it is assumed to be valid and is not verified.
1093 -) Make the CRL encoding routines work with empty SEQUENCE OF. The
1094 macros previously used would not encode an empty SEQUENCE OF
1095 and break the signature.
1097 [This change does not apply to 0.9.7.]
1099 *) Zero the premaster secret after deriving the master secret in
1103 +) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
1104 to data. This was previously part of the PKCS7 ASN1 code. This
1105 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
1106 [Steve Henson, reported by Kenneth R. Robinette
1107 <support@securenetterm.com>]
1109 +) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
1110 routines: without these tracing memory leaks is very painful.
1111 Fix leaks in PKCS12 and PKCS7 routines.
1114 *) Add some EVP_add_digest_alias registrations (as found in
1115 OpenSSL_add_all_digests()) to SSL_library_init()
1116 aka OpenSSL_add_ssl_algorithms(). This provides improved
1117 compatibility with peers using X.509 certificates
1118 with unconventional AlgorithmIdentifier OIDs.
1121 *) Fix for Irix with NO_ASM.
1122 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
1124 *) ./config script fixes.
1125 [Ulf Moeller, Richard Levitte]
1127 +) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
1128 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
1129 effectively meant GeneralizedTime would never be used. Now it
1130 is initialised to -1 but X509_time_adj() now has to check the value
1131 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
1132 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
1133 [Steve Henson, reported by Kenneth R. Robinette
1134 <support@securenetterm.com>]
1136 +) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
1137 result in a zero length in the ASN1_INTEGER structure which was
1138 not consistent with the structure when d2i_ASN1_INTEGER() was used
1139 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
1140 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
1141 where it did not print out a minus for negative ASN1_INTEGER.
1144 *) Fix 'openssl passwd -1'.
1147 +) Add summary printout to ocsp utility. The various functions which
1148 convert status values to strings have been renamed to:
1149 OCSP_response_status_str(), OCSP_cert_status_str() and
1150 OCSP_crl_reason_str() and are no longer static. New options
1151 to verify nonce values and to disable verification. OCSP response
1152 printout format cleaned up.
1155 +) Add additional OCSP certificate checks. These are those specified
1156 in RFC2560. This consists of two separate checks: the CA of the
1157 certificate being checked must either be the OCSP signer certificate
1158 or the issuer of the OCSP signer certificate. In the latter case the
1159 OCSP signer certificate must contain the OCSP signing extended key
1160 usage. This check is performed by attempting to match the OCSP
1161 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
1162 in the OCSP_CERTID structures of the response.
1165 +) Initial OCSP certificate verification added to OCSP_basic_verify()
1166 and related routines. This uses the standard OpenSSL certificate
1167 verify routines to perform initial checks (just CA validity) and
1168 to obtain the certificate chain. Then additional checks will be
1169 performed on the chain. Currently the root CA is checked to see
1170 if it is explicitly trusted for OCSP signing. This is used to set
1171 a root CA as a global signing root: that is any certificate that
1172 chains to that CA is an acceptable OCSP signing certificate.
1175 +) New '-extfile ...' option to 'openssl ca' for reading X.509v3
1176 extensions from a separate configuration file.
1177 As when reading extensions from the main configuration file,
1178 the '-extensions ...' option may be used for specifying the

1182 *) Change PKCS12_key_gen_asc() so it can cope with non null
1183 terminated strings whose length is passed in the passlen
1184 parameter, for example from PEM callbacks. This was done
1185 by adding an extra length parameter to asc2uni().
1186 [Steve Henson, reported by <oddissey@samsung.co.kr>]
1188 +) New OCSP utility. Allows OCSP requests to be generated or
1189 read. The request can be sent to a responder and the output
1190 parsed, outputed or printed in text form. Not complete yet:
1191 still needs to check the OCSP response validity.
1194 +) New subcommands for 'openssl ca':
1195 'openssl ca -status <serial>' prints the status of the cert with
1196 the given serial number (according to the index file).
1197 'openssl ca -updatedb' updates the expiry status of certificates
1199 [Massimiliano Pala <madwolf@comune.modena.it>]
1201 +) New '-newreq-nodes' command option to CA.pl. This is like
1202 '-newreq', but calls 'openssl req' with the '-nodes' option
1203 so that the resulting key is not encrypted.
1204 [Damien Miller <djm@mindrot.org>]
1206 +) New configuration for the GNU Hurd.
1207 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
1209 +) Initial code to implement OCSP basic response verify. This
1210 is currently incomplete. Currently just finds the signer's
1211 certificate and verifies the signature on the response.
1214 +) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
1215 value of OPENSSLDIR. This is available via the new '-d' option
1216 to 'openssl version', and is also included in 'openssl version -a'.
1219 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
1220 call failed, free the DSA structure.
1223 +) Allowing defining memory allocation callbacks that will be given
1224 file name and line number information in additional arguments
1225 (a const char* and an int). The basic functionality remains, as
1226 well as the original possibility to just replace malloc(),
1227 realloc() and free() by functions that do not know about these
1228 additional arguments. To register and find out the current
1229 settings for extended allocation functions, the following
1230 functions are provided:
1232 CRYPTO_set_mem_ex_functions
1233 CRYPTO_set_locked_mem_ex_functions
1234 CRYPTO_get_mem_ex_functions
1235 CRYPTO_get_locked_mem_ex_functions
1237 These work the same way as CRYPTO_set_mem_functions and friends.
1238 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
1239 extended allocation function is enabled.
1240 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
1241 a conventional allocation function is enabled.
1242 [Richard Levitte, Bodo Moeller]
1244 *) Fix to uni2asc() to cope with zero length Unicode strings.
1245 These are present in some PKCS#12 files.
1248 +) Finish off removing the remaining LHASH function pointer casts.
1249 There should no longer be any prototype-casting required when using
1250 the LHASH abstraction, and any casts that remain are "bugs". See
1251 the callback types and macros at the head of lhash.h for details
1252 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
1255 +) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
1256 If /dev/[u]random devices are not available or do not return enough
1257 entropy, EGD style sockets (served by EGD or PRNGD) will automatically
1259 The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
1260 /etc/entropy will be queried once each in this sequence, quering stops
1261 when enough entropy was collected without querying more sockets.
1264 +) Change the Unix RAND_poll() variant to be able to poll several
1265 random devices, as specified by DEVRANDOM, until a sufficient amount
1266 of data has been collected. We spend at most 10 ms on each file
1267 (select timeout) and read in non-blocking mode. DEVRANDOM now
1268 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
1269 (previously it was just the string "/dev/urandom"), so on typical
1270 platforms the 10 ms delay will never occur.
1271 Also separate out the Unix variant to its own file, rand_unix.c.
1272 For VMS, there's a currently-empty rand_vms.c.
1275 +) Move OCSP client related routines to ocsp_cl.c. These
1276 provide utility functions which an application needing
1277 to issue a request to an OCSP responder and analyse the
1278 response will typically need: as opposed to those which an
1279 OCSP responder itself would need which will be added later.
1281 OCSP_request_sign() signs an OCSP request with an API similar
1282 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
1283 response. OCSP_response_get1_basic() extracts basic response
1284 from response. OCSP_resp_find_status(): finds and extracts status
1285 information from an OCSP_CERTID structure (which will be created
1286 when the request structure is built). These are built from lower
1287 level functions which work on OCSP_SINGLERESP structures but
1288 wont normally be used unless the application wishes to examine
1289 extensions in the OCSP response for example.
1291 Replace nonce routines with a pair of functions.
1292 OCSP_request_add1_nonce() adds a nonce value and optionally
1293 generates a random value. OCSP_check_nonce() checks the
1294 validity of the nonce in an OCSP response.
1297 +) Change function OCSP_request_add() to OCSP_request_add0_id().
1298 This doesn't copy the supplied OCSP_CERTID and avoids the
1299 need to free up the newly created id. Change return type
1300 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
1301 This can then be used to add extensions to the request.
1302 Deleted OCSP_request_new(), since most of its functionality
1303 is now in OCSP_REQUEST_new() (and the case insensitive name
1304 clash) apart from the ability to set the request name which
1305 will be added elsewhere.
1308 +) Update OCSP API. Remove obsolete extensions argument from
1309 various functions. Extensions are now handled using the new
1310 OCSP extension code. New simple OCSP HTTP function which
1311 can be used to send requests and parse the response.
1314 +) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
1315 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
1316 uses the special reorder version of SET OF to sort the attributes
1317 and reorder them to match the encoded order. This resolves a long
1318 standing problem: a verify on a PKCS7 structure just after signing
1319 it used to fail because the attribute order did not match the
1320 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
1321 it uses the received order. This is necessary to tolerate some broken
1322 software that does not order SET OF. This is handled by encoding
1323 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
1324 to produce the required SET OF.
1327 +) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
1328 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
1329 files to get correct declarations of the ASN.1 item variables.
1332 +) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
1333 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
1334 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
1335 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
1336 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
1337 ASN1_ITEM and no wrapper functions.
1340 +) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
1341 replace the old function pointer based I/O routines. Change most of
1342 the *_d2i_bio() and *_d2i_fp() functions to use these.
1345 +) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
1346 lines, recognice more "algorithms" that can be deselected, and make
1347 it complain about algorithm deselection that isn't recognised.
1350 +) New ASN1 functions to handle dup, sign, verify, digest, pack and
1351 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
1352 to use new functions. Add NO_ASN1_OLD which can be set to remove
1353 some old style ASN1 functions: this can be used to determine if old
1354 code will still work when these eventually go away.
1357 +) New extension functions for OCSP structures, these follow the
1358 same conventions as certificates and CRLs.
1361 +) New function X509V3_add1_i2d(). This automatically encodes and
1362 adds an extension. Its behaviour can be customised with various
1363 flags to append, replace or delete. Various wrappers added for
1364 certifcates and CRLs.
1367 +) Fix to avoid calling the underlying ASN1 print routine when
1368 an extension cannot be parsed. Correct a typo in the
1369 OCSP_SERVICELOC extension. Tidy up print OCSP format.
1372 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
1373 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
1374 when writing a 32767 byte record.
1375 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
1377 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
1378 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
1380 (RSA objects have a reference count access to which is protected
1381 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
1382 so they are meant to be shared between threads.)
1383 [Bodo Moeller, Geoff Thorpe; original patch submitted by
1384 "Reddie, Steven" <Steven.Reddie@ca.com>]
1386 +) Make mkdef.pl parse some of the ASN1 macros and add apropriate
1387 entries for variables.
1390 *) Fix a deadlock in CRYPTO_mem_leaks().
1393 +) Add functionality to apps/openssl.c for detecting locking
1394 problems: As the program is single-threaded, all we have
1395 to do is register a locking callback using an array for
1396 storing which locks are currently held by the program.
1399 +) Use a lock around the call to CRYPTO_get_ex_new_index() in
1400 SSL_get_ex_data_X509_STORE_idx(), which is used in
1401 ssl_verify_cert_chain() and thus can be called at any time
1402 during TLS/SSL handshakes so that thread-safety is essential.
1403 Unfortunately, the ex_data design is not at all suited
1404 for multi-threaded use, so it probably should be abolished.
1407 +) Added Broadcom "ubsec" ENGINE to OpenSSL.
1408 [Broadcom, tweaked and integrated by Geoff Thorpe]
1410 +) Move common extension printing code to new function
1411 X509V3_print_extensions(). Reorganise OCSP print routines and
1412 implement some needed OCSP ASN1 functions. Add OCSP extensions.
1415 +) New function X509_signature_print() to remove duplication in some
1419 +) Add a special meaning when SET OF and SEQUENCE OF flags are both
1420 set (this was treated exactly the same as SET OF previously). This
1421 is used to reorder the STACK representing the structure to match the
1422 encoding. This will be used to get round a problem where a PKCS7
1423 structure which was signed could not be verified because the STACK
1424 order did not reflect the encoded order.
1427 +) Reimplement the OCSP ASN1 module using the new code.
1430 +) Update the X509V3 code to permit the use of an ASN1_ITEM structure
1431 for its ASN1 operations. The old style function pointers still exist
1432 for now but they will eventually go away.
1435 +) Merge in replacement ASN1 code from the ASN1 branch. This almost
1436 completely replaces the old ASN1 functionality with a table driven
1437 encoder and decoder which interprets an ASN1_ITEM structure describing
1438 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
1439 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
1440 has also been converted to the new form.
1443 +) Change BN_mod_exp_recp so that negative moduli are tolerated
1444 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
1445 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
1446 for negative moduli.
1449 +) Fix BN_uadd and BN_usub: Always return non-negative results instead
1450 of not touching the result's sign bit.
1453 +) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
1457 +) Changed the LHASH code to use prototypes for callbacks, and created
1458 macros to declare and implement thin (optionally static) functions
1459 that provide type-safety and avoid function pointer casting for the
1460 type-specific callbacks.
1463 *) Use better test patterns in bntest.
1466 +) Added Kerberos Cipher Suites to be used with TLS, as written in
1468 [Veers Staats <staatsvr@asc.hpc.mil>,
1469 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
1471 *) rand_win.c fix for Borland C.
1474 *) BN_rshift bugfix for n == 0.
1477 +) Reformat the FAQ so the different questions and answers can be divided
1478 in sections depending on the subject.
1481 +) Have the zlib compression code load ZLIB.DLL dynamically under
1485 +) New function BN_mod_sqrt for computing square roots modulo a prime
1486 (using the probabilistic Tonelli-Shanks algorithm unless
1487 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
1488 be handled deterministically).
1489 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
1491 *) Add a 'bctest' script that checks for some known 'bc' bugs
1492 so that 'make test' does not abort just because 'bc' is broken.
1495 *) Store verify_result within SSL_SESSION also for client side to
1496 avoid potential security hole. (Re-used sessions on the client side
1497 always resulted in verify_result==X509_V_OK, not using the original
1498 result of the server certificate verification.)
1501 +) Make BN_mod_inverse faster by explicitly handling small quotients
1502 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
1503 512 bits], about 30% for larger ones [1024 or 2048 bits].)
1506 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
1507 SSL3_RT_APPLICATION_DATA, return 0.
1508 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
1512 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
1513 releases, have been re-implemented by renaming the previous
1514 implementations of ssl2_read and ssl3_read to ssl2_read_internal
1515 and ssl3_read_internal, respectively, and adding 'peek' parameters
1516 to them. The new ssl[23]_{read,peek} functions are calls to
1517 ssl[23]_read_internal with the 'peek' flag set appropriately.
1518 A 'peek' parameter has also been added to ssl3_read_bytes, which
1519 does the actual work for ssl3_read_internal.
1522 +) New function BN_kronecker.
1525 +) Fix BN_gcd so that it works on negative inputs; the result is
1526 positive unless both parameters are zero.
1527 Previously something reasonably close to an infinite loop was
1528 possible because numbers could be growing instead of shrinking
1529 in the implementation of Euclid's algorithm.
1532 +) Fix BN_is_word() and BN_is_one() macros to take into account the
1533 sign of the number in question.
1535 Fix BN_is_word(a,w) to work correctly for w == 0.
1537 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
1538 because its test if the absolute value of 'a' equals 'w'.
1539 Note that BN_abs_is_word does *not* handle w == 0 reliably;
1540 it exists mostly for use in the implementations of BN_is_zero(),
1541 BN_is_one(), and BN_is_word().
1544 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
1545 the method-specific "init()" handler. Also clean up ex_data after
1546 calling the method-specific "finish()" handler. Previously, this was
1547 happening the other way round.
1550 +) New function BN_swap.
1553 +) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
1554 the exponentiation functions are more likely to produce reasonable
1555 results on negative inputs.
1558 +) Change BN_mod_mul so that the result is always non-negative.
1559 Previously, it could be negative if one of the factors was negative;
1560 I don't think anyone really wanted that behaviour.
1563 +) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
1564 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
1565 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
1566 and add new functions:
1575 BN_mod_lshift1_quick
1579 These functions always generate non-negative results.
1581 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
1582 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
1584 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
1585 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
1586 be reduced modulo m.
1587 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
1589 +) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
1590 was actually never needed) and in BN_mul(). The removal in BN_mul()
1591 required a small change in bn_mul_part_recursive() and the addition
1592 of the functions bn_cmp_part_words(), bn_sub_part_words() and
1593 bn_add_part_words(), which do the same thing as bn_cmp_words(),
1594 bn_sub_words() and bn_add_words() except they take arrays with
1598 +) In 'openssl passwd', verify passwords read from the terminal
1599 unless the '-salt' option is used (which usually means that
1600 verification would just waste user's time since the resulting
1601 hash is going to be compared with some given password hash)
1602 or the new '-noverify' option is used.
1604 This is an incompatible change, but it does not affect
1605 non-interactive use of 'openssl passwd' (passwords on the command
1606 line, '-stdin' option, '-in ...' option) and thus should not
1610 +) Remove all references to RSAref, since there's no more need for it.
1613 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
1614 The previous value, 12, was not always sufficient for BN_mod_exp().
1617 +) Make DSO load along a path given through an environment variable
1618 (SHLIB_PATH) with shl_load().
1621 +) Constify the ENGINE code as a result of BIGNUM constification.
1622 Also constify the RSA code and most things related to it. In a
1623 few places, most notable in the depth of the ASN.1 code, ugly
1624 casts back to non-const were required (to be solved at a later
1628 +) Make it so the openssl application has all engines loaded by default.
1631 +) Constify the BIGNUM routines a little more.
1634 *) Make sure that shared libraries get the internal name engine with
1635 the full version number and not just 0. This should mark the
1636 shared libraries as not backward compatible. Of course, this should
1637 be changed again when we can guarantee backward binary compatibility.
1640 +) Add the following functions:
1642 ENGINE_load_cswift()
1644 ENGINE_load_atalla()
1646 ENGINE_load_builtin_engines()
1648 That way, an application can itself choose if external engines that
1649 are built-in in OpenSSL shall ever be used or not. The benefit is
1650 that applications won't have to be linked with libdl or other dso
1651 libraries unless it's really needed.
1653 Changed 'openssl engine' to load all engines on demand.
1654 Changed the engine header files to avoid the duplication of some
1655 declarations (they differed!).
1658 +) 'openssl engine' can now list capabilities.
1661 +) Better error reporting in 'openssl engine'.
1664 +) Never call load_dh_param(NULL) in s_server.
1667 +) Add engine application. It can currently list engines by name and
1668 identity, and test if they are actually available.
1671 +) Add support for shared libraries under Irix.
1672 [Albert Chin-A-Young <china@thewrittenword.com>]
1674 +) Improve RPM specification file by forcing symbolic linking and making
1675 sure the installed documentation is also owned by root.root.
1676 [Damien Miller <djm@mindrot.org>]
1678 +) Add configuration option to build on Linux on both big-endian and
1680 [Ralf Baechle <ralf@uni-koblenz.de>]
1682 +) Give the OpenSSL applications more possibilities to make use of
1683 keys (public as well as private) handled by engines.
1686 +) Add OCSP code that comes from CertCo.
1689 +) Add VMS support for the Rijndael code.
1692 +) Added untested support for Nuron crypto accelerator.
1695 +) Add support for external cryptographic devices. This code was
1696 previously distributed separately as the "engine" branch.
1697 [Geoff Thorpe, Richard Levitte]
1699 +) Rework the filename-translation in the DSO code. It is now possible to
1700 have far greater control over how a "name" is turned into a filename
1701 depending on the operating environment and any oddities about the
1702 different shared library filenames on each system.
1705 +) Support threads on FreeBSD-elf in Configure.
1708 +) Add the possibility to create shared libraries on HP-UX
1711 +) Fix for SHA1 assembly problem with MASM: it produces
1712 warnings about corrupt line number information when assembling
1713 with debugging information. This is caused by the overlapping
1715 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
1718 NCONF_get_number() has no error checking at all. As a replacement,
1719 NCONF_get_number_e() is defined (_e for "error checking") and is
1720 promoted strongly. The old NCONF_get_number is kept around for
1721 binary backward compatibility.
1722 Make it possible for methods to load from something other than a BIO,
1723 by providing a function pointer that is given a name instead of a BIO.
1724 For example, this could be used to load configuration data from an
1728 *) Fix typo in get_cert_by_subject() in by_dir.c
1729 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
1731 *) Rework the system to generate shared libraries:
1733 - Make note of the expected extension for the shared libraries and
1734 if there is a need for symbolic links from for example libcrypto.so.0
1735 to libcrypto.so.0.9.7. There is extended info in Configure for
1738 - Make as few rebuilds of the shared libraries as possible.
1740 - Still avoid linking the OpenSSL programs with the shared libraries.
1742 - When installing, install the shared libraries separately from the
1746 +) Fix for non blocking accept BIOs. Added new I/O special reason
1747 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
1748 with non blocking I/O was not possible because no retry code was
1749 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
1753 +) Added the beginnings of Rijndael support.
1756 +) Fix for bug in DirectoryString mask setting. Add support for
1757 X509_NAME_print_ex() in 'req' and X509_print_ex() function
1758 to allow certificate printing to more controllable, additional
1759 'certopt' option to 'x509' to allow new printing options to be
1763 +) Clean old EAY MD5 hack from e_os.h.
1766 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
1768 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
1769 and not in SSL_clear because the latter is also used by the
1770 accept/connect functions; previously, the settings made by
1771 SSL_set_read_ahead would be lost during the handshake.
1772 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
1774 *) Correct util/mkdef.pl to be selective about disabled algorithms.
1775 Previously, it would create entries for disableed algorithms no
1779 *) Added several new manual pages for SSL_* function.
1782 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
1784 *) In ssl23_get_client_hello, generate an error message when faced
1785 with an initial SSL 3.0/TLS record that is too small to contain the
1786 first two bytes of the ClientHello message, i.e. client_version.
1787 (Note that this is a pathologic case that probably has never happened
1788 in real life.) The previous approach was to use the version number
1789 from the record header as a substitute; but our protocol choice
1790 should not depend on that one because it is not authenticated
1791 by the Finished messages.
1794 *) More robust randomness gathering functions for Windows.
1795 [Jeffrey Altman <jaltman@columbia.edu>]
1797 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
1798 not set then we don't setup the error code for issuer check errors
1799 to avoid possibly overwriting other errors which the callback does
1800 handle. If an application does set the flag then we assume it knows
1801 what it is doing and can handle the new informational codes
1805 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
1806 a general "ANY" type, as such it should be able to decode anything
1807 including tagged types. However it didn't check the class so it would
1808 wrongly interpret tagged types in the same way as their universal
1809 counterpart and unknown types were just rejected. Changed so that the
1810 tagged and unknown types are handled in the same way as a SEQUENCE:
1811 that is the encoding is stored intact. There is also a new type
1812 "V_ASN1_OTHER" which is used when the class is not universal, in this
1813 case we have no idea what the actual type is so we just lump them all
1817 *) On VMS, stdout may very well lead to a file that is written to
1818 in a record-oriented fashion. That means that every write() will
1819 write a separate record, which will be read separately by the
1820 programs trying to read from it. This can be very confusing.
1822 The solution is to put a BIO filter in the way that will buffer
1823 text until a linefeed is reached, and then write everything a
1824 line at a time, so every record written will be an actual line,
1825 not chunks of lines and not (usually doesn't happen, but I've
1826 seen it once) several lines in one record. BIO_f_linebuffer() is
1829 Currently, it's a VMS-only method, because that's where it has
1830 been tested well enough.
1833 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
1834 it can return incorrect results.
1835 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
1836 but it was in 0.9.6-beta[12].)
1839 *) Disable the check for content being present when verifying detached
1840 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
1841 include zero length content when signing messages.
1844 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
1845 BIO_ctrl (for BIO pairs).
1848 *) Add DSO method for VMS.
1851 *) Bug fix: Montgomery multiplication could produce results with the
1855 *) Add RPM specification openssl.spec and modify it to build three
1856 packages. The default package contains applications, application
1857 documentation and run-time libraries. The devel package contains
1858 include files, static libraries and function documentation. The
1859 doc package contains the contents of the doc directory. The original
1860 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
1863 *) Add a large number of documentation files for many SSL routines.
1864 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1866 *) Add a configuration entry for Sony News 4.
1867 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
1869 *) Don't set the two most significant bits to one when generating a
1870 random number < q in the DSA library.
1873 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
1874 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
1875 the underlying transport is blocking) if a handshake took place.
1876 (The default behaviour is needed by applications such as s_client
1877 and s_server that use select() to determine when to use SSL_read;
1878 but for applications that know in advance when to expect data, it
1879 just makes things more complicated.)
1882 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
1886 *) Add a few more EBCDIC conditionals that make `req' and `x509'
1887 work better on such systems.
1888 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1890 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
1891 Update PKCS12_parse() so it copies the friendlyName and the
1892 keyid to the certificates aux info.
1895 *) Fix bug in PKCS7_verify() which caused an infinite loop
1896 if there was more than one signature.
1897 [Sven Uszpelkat <su@celocom.de>]
1899 *) Major change in util/mkdef.pl to include extra information
1900 about each symbol, as well as presentig variables as well
1901 as functions. This change means that there's n more need
1902 to rebuild the .num files when some algorithms are excluded.
1905 *) Allow the verify time to be set by an application,
1906 rather than always using the current time.
1909 *) Phase 2 verify code reorganisation. The certificate
1910 verify code now looks up an issuer certificate by a
1911 number of criteria: subject name, authority key id
1912 and key usage. It also verifies self signed certificates
1913 by the same criteria. The main comparison function is
1914 X509_check_issued() which performs these checks.
1916 Lot of changes were necessary in order to support this
1917 without completely rewriting the lookup code.
1919 Authority and subject key identifier are now cached.
1921 The LHASH 'certs' is X509_STORE has now been replaced
1922 by a STACK_OF(X509_OBJECT). This is mainly because an
1923 LHASH can't store or retrieve multiple objects with
1924 the same hash value.
1926 As a result various functions (which were all internal
1927 use only) have changed to handle the new X509_STORE
1928 structure. This will break anything that messed round
1929 with X509_STORE internally.
1931 The functions X509_STORE_add_cert() now checks for an
1932 exact match, rather than just subject name.
1934 The X509_STORE API doesn't directly support the retrieval
1935 of multiple certificates matching a given criteria, however
1936 this can be worked round by performing a lookup first
1937 (which will fill the cache with candidate certificates)
1938 and then examining the cache for matches. This is probably
1939 the best we can do without throwing out X509_LOOKUP
1940 entirely (maybe later...).
1942 The X509_VERIFY_CTX structure has been enhanced considerably.
1944 All certificate lookup operations now go via a get_issuer()
1945 callback. Although this currently uses an X509_STORE it
1946 can be replaced by custom lookups. This is a simple way
1947 to bypass the X509_STORE hackery necessary to make this
1948 work and makes it possible to use more efficient techniques
1949 in future. A very simple version which uses a simple
1950 STACK for its trusted certificate store is also provided
1951 using X509_STORE_CTX_trusted_stack().
1953 The verify_cb() and verify() callbacks now have equivalents
1954 in the X509_STORE_CTX structure.
1956 X509_STORE_CTX also has a 'flags' field which can be used
1957 to customise the verify behaviour.
1960 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
1961 excludes S/MIME capabilities.
1964 *) When a certificate request is read in keep a copy of the
1965 original encoding of the signed data and use it when outputing
1966 again. Signatures then use the original encoding rather than
1967 a decoded, encoded version which may cause problems if the
1968 request is improperly encoded.
1971 *) For consistency with other BIO_puts implementations, call
1972 buffer_write(b, ...) directly in buffer_puts instead of calling
1975 In BIO_puts, increment b->num_write as in BIO_write.
1976 [Peter.Sylvester@EdelWeb.fr]
1978 *) Fix BN_mul_word for the case where the word is 0. (We have to use
1979 BN_zero, we may not return a BIGNUM with an array consisting of
1983 *) Avoid calling abort() from within the library when problems are
1984 detected, except if preprocessor symbols have been defined
1985 (such as REF_CHECK, BN_DEBUG etc.).
1988 *) New openssl application 'rsautl'. This utility can be
1989 used for low level RSA operations. DER public key
1990 BIO/fp routines also added.
1993 *) New Configure entry and patches for compiling on QNX 4.
1994 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
1996 *) A demo state-machine implementation was sponsored by
1997 Nuron (http://www.nuron.com/) and is now available in
1998 demos/state_machine.
2001 *) New options added to the 'dgst' utility for signature
2002 generation and verification.
2005 *) Unrecognized PKCS#7 content types are now handled via a
2006 catch all ASN1_TYPE structure. This allows unsupported
2007 types to be stored as a "blob" and an application can
2008 encode and decode it manually.
2011 *) Fix various signed/unsigned issues to make a_strex.c
2013 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
2015 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
2016 length if passed a buffer. ASN1_INTEGER_to_BN failed
2017 if passed a NULL BN and its argument was negative.
2018 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
2020 *) Modification to PKCS#7 encoding routines to output definite
2021 length encoding. Since currently the whole structures are in
2022 memory there's not real point in using indefinite length
2023 constructed encoding. However if OpenSSL is compiled with
2024 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
2027 *) Added BIO_vprintf() and BIO_vsnprintf().
2030 *) Added more prefixes to parse for in the the strings written
2031 through a logging bio, to cover all the levels that are available
2032 through syslog. The prefixes are now:
2034 PANIC, EMERG, EMR => LOG_EMERG
2035 ALERT, ALR => LOG_ALERT
2036 CRIT, CRI => LOG_CRIT
2037 ERROR, ERR => LOG_ERR
2038 WARNING, WARN, WAR => LOG_WARNING
2039 NOTICE, NOTE, NOT => LOG_NOTICE
2040 INFO, INF => LOG_INFO
2041 DEBUG, DBG => LOG_DEBUG
2043 and as before, if none of those prefixes are present at the
2044 beginning of the string, LOG_ERR is chosen.
2046 On Win32, the LOG_* levels are mapped according to this:
2048 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
2049 LOG_WARNING => EVENTLOG_WARNING_TYPE
2050 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
2054 *) Made it possible to reconfigure with just the configuration
2055 argument "reconf" or "reconfigure". The command line arguments
2056 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
2057 and are retrieved from there when reconfiguring.
2061 [Assar Westerlund <assar@sics.se>, Richard Levitte]
2063 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
2066 *) The obj_dat.pl script was messing up the sorting of object
2067 names. The reason was that it compared the quoted version
2068 of strings as a result "OCSP" > "OCSP Signing" because
2069 " > SPACE. Changed script to store unquoted versions of
2070 names and add quotes on output. It was also omitting some
2071 names from the lookup table if they were given a default
2072 value (that is if SN is missing it is given the same
2073 value as LN and vice versa), these are now added on the
2074 grounds that if an object has a name we should be able to
2075 look it up. Finally added warning output when duplicate
2076 short or long names are found.
2079 *) Changes needed for Tandem NSK.
2080 [Scott Uroff <scott@xypro.com>]
2082 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
2083 RSA_padding_check_SSLv23(), special padding was never detected
2084 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
2085 version rollback attacks was not effective.
2087 In s23_clnt.c, don't use special rollback-attack detection padding
2088 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
2089 client; similarly, in s23_srvr.c, don't do the rollback check if
2090 SSL 2.0 is the only protocol enabled in the server.
2093 *) Make it possible to get hexdumps of unprintable data with 'openssl
2094 asn1parse'. By implication, the functions ASN1_parse_dump() and
2095 BIO_dump_indent() are added.
2098 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
2099 these print out strings and name structures based on various
2100 flags including RFC2253 support and proper handling of
2101 multibyte characters. Added options to the 'x509' utility
2102 to allow the various flags to be set.
2105 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
2106 Also change the functions X509_cmp_current_time() and
2107 X509_gmtime_adj() work with an ASN1_TIME structure,
2108 this will enable certificates using GeneralizedTime in validity
2109 dates to be checked.
2112 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
2113 negative public key encodings) on by default,
2114 NO_NEG_PUBKEY_BUG can be set to disable it.
2117 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
2118 content octets. An i2c_ASN1_OBJECT is unnecessary because
2119 the encoding can be trivially obtained from the structure.
2122 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
2123 not read locks (CRYPTO_r_[un]lock).
2126 *) A first attempt at creating official support for shared
2127 libraries through configuration. I've kept it so the
2128 default is static libraries only, and the OpenSSL programs
2129 are always statically linked for now, but there are
2130 preparations for dynamic linking in place.
2131 This has been tested on Linux and Tru64.
2134 *) Randomness polling function for Win9x, as described in:
2135 Peter Gutmann, Software Generation of Practically Strong
2139 *) Fix so PRNG is seeded in req if using an already existing
2143 *) New options to smime application. -inform and -outform
2144 allow alternative formats for the S/MIME message including
2145 PEM and DER. The -content option allows the content to be
2146 specified separately. This should allow things like Netscape
2147 form signing output easier to verify.
2150 *) Fix the ASN1 encoding of tags using the 'long form'.
2153 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
2154 STRING types. These convert content octets to and from the
2155 underlying type. The actual tag and length octets are
2156 already assumed to have been read in and checked. These
2157 are needed because all other string types have virtually
2158 identical handling apart from the tag. By having versions
2159 of the ASN1 functions that just operate on content octets
2160 IMPLICIT tagging can be handled properly. It also allows
2161 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
2162 and ASN1_INTEGER are identical apart from the tag.
2165 *) Change the handling of OID objects as follows:
2167 - New object identifiers are inserted in objects.txt, following
2168 the syntax given in objects.README.
2169 - objects.pl is used to process obj_mac.num and create a new
2171 - obj_dat.pl is used to create a new obj_dat.h, using the data in
2174 This is currently kind of a hack, and the perl code in objects.pl
2175 isn't very elegant, but it works as I intended. The simplest way
2176 to check that it worked correctly is to look in obj_dat.h and
2177 check the array nid_objs and make sure the objects haven't moved
2178 around (this is important!). Additions are OK, as well as
2179 consistent name changes.
2182 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
2185 *) Addition of the command line parameter '-rand file' to 'openssl req'.
2186 The given file adds to whatever has already been seeded into the
2187 random pool through the RANDFILE configuration file option or
2188 environment variable, or the default random state file.
2191 *) mkstack.pl now sorts each macro group into lexical order.
2192 Previously the output order depended on the order the files
2193 appeared in the directory, resulting in needless rewriting
2197 *) Patches to make OpenSSL compile under Win32 again. Mostly
2198 work arounds for the VC++ problem that it treats func() as
2199 func(void). Also stripped out the parts of mkdef.pl that
2200 added extra typesafe functions: these no longer exist.
2203 *) Reorganisation of the stack code. The macros are now all
2204 collected in safestack.h . Each macro is defined in terms of
2205 a "stack macro" of the form SKM_<name>(type, a, b). The
2206 DEBUG_SAFESTACK is now handled in terms of function casts,
2207 this has the advantage of retaining type safety without the
2208 use of additional functions. If DEBUG_SAFESTACK is not defined
2209 then the non typesafe macros are used instead. Also modified the
2210 mkstack.pl script to handle the new form. Needs testing to see
2211 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
2212 the default if no major problems. Similar behaviour for ASN1_SET_OF
2213 and PKCS12_STACK_OF.
2216 *) When some versions of IIS use the 'NET' form of private key the
2217 key derivation algorithm is different. Normally MD5(password) is
2218 used as a 128 bit RC4 key. In the modified case
2219 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
2220 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
2221 as the old Netscape_RSA functions except they have an additional
2222 'sgckey' parameter which uses the modified algorithm. Also added
2223 an -sgckey command line option to the rsa utility. Thanks to
2224 Adrian Peck <bertie@ncipher.com> for posting details of the modified
2225 algorithm to openssl-dev.
2228 *) The evp_local.h macros were using 'c.##kname' which resulted in
2229 invalid expansion on some systems (SCO 5.0.5 for example).
2230 Corrected to 'c.kname'.
2231 [Phillip Porch <root@theporch.com>]
2233 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
2234 a STACK of email addresses from a certificate or request, these look
2235 in the subject name and the subject alternative name extensions and
2236 omit any duplicate addresses.
2239 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
2240 This makes DSA verification about 2 % faster.
2243 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
2244 (meaning that now 2^5 values will be precomputed, which is only 4 KB
2245 plus overhead for 1024 bit moduli).
2246 This makes exponentiations about 0.5 % faster for 1024 bit
2247 exponents (as measured by "openssl speed rsa2048").
2250 *) Rename memory handling macros to avoid conflicts with other
2252 Malloc => OPENSSL_malloc
2253 Malloc_locked => OPENSSL_malloc_locked
2254 Realloc => OPENSSL_realloc
2255 Free => OPENSSL_free
2258 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
2259 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
2262 *) CygWin32 support.
2263 [John Jarvie <jjarvie@newsguy.com>]
2265 *) The type-safe stack code has been rejigged. It is now only compiled
2266 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
2267 by default all type-specific stack functions are "#define"d back to
2268 standard stack functions. This results in more streamlined output
2269 but retains the type-safety checking possibilities of the original
2273 *) The STACK code has been cleaned up, and certain type declarations
2274 that didn't make a lot of sense have been brought in line. This has
2275 also involved a cleanup of sorts in safestack.h to more correctly
2276 map type-safe stack functions onto their plain stack counterparts.
2277 This work has also resulted in a variety of "const"ifications of
2278 lots of the code, especially "_cmp" operations which should normally
2279 be prototyped with "const" parameters anyway.
2282 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
2283 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
2284 (The PRNG state consists of two parts, the large pool 'state' and 'md',
2285 where all of 'md' is used each time the PRNG is used, but 'state'
2286 is used only indexed by a cyclic counter. As entropy may not be
2287 well distributed from the beginning, 'md' is important as a
2288 chaining variable. However, the output function chains only half
2289 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
2290 all of 'md', and seeding with STATE_SIZE dummy bytes will result
2291 in all of 'state' being rewritten, with the new values depending
2292 on virtually all of 'md'. This overcomes the 80 bit limitation.)
2295 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
2296 the handshake is continued after ssl_verify_cert_chain();
2297 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
2298 can lead to 'unexplainable' connection aborts later.
2299 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
2301 *) Major EVP API cipher revision.
2302 Add hooks for extra EVP features. This allows various cipher
2303 parameters to be set in the EVP interface. Support added for variable
2304 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
2305 setting of RC2 and RC5 parameters.
2307 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
2310 Remove lots of duplicated code from the EVP library. For example *every*
2311 cipher init() function handles the 'iv' in the same way according to the
2312 cipher mode. They also all do nothing if the 'key' parameter is NULL and
2313 for CFB and OFB modes they zero ctx->num.
2315 New functionality allows removal of S/MIME code RC2 hack.
2317 Most of the routines have the same form and so can be declared in terms
2320 By shifting this to the top level EVP_CipherInit() it can be removed from
2321 all individual ciphers. If the cipher wants to handle IVs or keys
2322 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
2325 Change lots of functions like EVP_EncryptUpdate() to now return a
2326 value: although software versions of the algorithms cannot fail
2327 any installed hardware versions can.
2330 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
2331 this option is set, tolerate broken clients that send the negotiated
2332 protocol version number instead of the requested protocol version
2336 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
2337 i.e. non-zero for export ciphersuites, zero otherwise.
2338 Previous versions had this flag inverted, inconsistent with
2339 rsa_tmp_cb (..._TMP_RSA_CB).
2340 [Bodo Moeller; problem reported by Amit Chopra]
2342 *) Add missing DSA library text string. Work around for some IIS
2343 key files with invalid SEQUENCE encoding.
2346 *) Add a document (doc/standards.txt) that list all kinds of standards
2347 and so on that are implemented in OpenSSL.
2350 *) Enhance c_rehash script. Old version would mishandle certificates
2351 with the same subject name hash and wouldn't handle CRLs at all.
2352 Added -fingerprint option to crl utility, to support new c_rehash
2356 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
2359 *) Fix for SSL server purpose checking. Server checking was
2360 rejecting certificates which had extended key usage present
2361 but no ssl client purpose.
2362 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
2364 *) Make PKCS#12 code work with no password. The PKCS#12 spec
2365 is a little unclear about how a blank password is handled.
2366 Since the password in encoded as a BMPString with terminating
2367 double NULL a zero length password would end up as just the
2368 double NULL. However no password at all is different and is
2369 handled differently in the PKCS#12 key generation code. NS
2370 treats a blank password as zero length. MSIE treats it as no
2371 password on export: but it will try both on import. We now do
2372 the same: PKCS12_parse() tries zero length and no password if
2373 the password is set to "" or NULL (NULL is now a valid password:
2374 it wasn't before) as does the pkcs12 application.
2377 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
2378 perror when PEM_read_bio_X509_REQ fails, the error message must
2379 be obtained from the error queue.
2382 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
2383 it in ERR_remove_state if appropriate, and change ERR_get_state
2384 accordingly to avoid race conditions (this is necessary because
2385 thread_hash is no longer constant once set).
2388 *) Bugfix for linux-elf makefile.one.
2391 *) RSA_get_default_method() will now cause a default
2392 RSA_METHOD to be chosen if one doesn't exist already.
2393 Previously this was only set during a call to RSA_new()
2394 or RSA_new_method(NULL) meaning it was possible for
2395 RSA_get_default_method() to return NULL.
2398 *) Added native name translation to the existing DSO code
2399 that will convert (if the flag to do so is set) filenames
2400 that are sufficiently small and have no path information
2401 into a canonical native form. Eg. "blah" converted to
2402 "libblah.so" or "blah.dll" etc.
2405 *) New function ERR_error_string_n(e, buf, len) which is like
2406 ERR_error_string(e, buf), but writes at most 'len' bytes
2407 including the 0 terminator. For ERR_error_string_n, 'buf'
2409 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
2411 *) CONF library reworked to become more general. A new CONF
2412 configuration file reader "class" is implemented as well as a
2413 new functions (NCONF_*, for "New CONF") to handle it. The now
2414 old CONF_* functions are still there, but are reimplemented to
2415 work in terms of the new functions. Also, a set of functions
2416 to handle the internal storage of the configuration data is
2417 provided to make it easier to write new configuration file
2418 reader "classes" (I can definitely see something reading a
2419 configuration file in XML format, for example), called _CONF_*,
2420 or "the configuration storage API"...
2422 The new configuration file reading functions are:
2424 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
2425 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
2427 NCONF_default, NCONF_WIN32
2429 NCONF_dump_fp, NCONF_dump_bio
2431 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
2432 NCONF_new creates a new CONF object. This works in the same way
2433 as other interfaces in OpenSSL, like the BIO interface.
2434 NCONF_dump_* dump the internal storage of the configuration file,
2435 which is useful for debugging. All other functions take the same
2436 arguments as the old CONF_* functions wth the exception of the
2437 first that must be a `CONF *' instead of a `LHASH *'.
2439 To make it easer to use the new classes with the old CONF_* functions,
2440 the function CONF_set_default_method is provided.
2443 *) Add '-tls1' option to 'openssl ciphers', which was already
2444 mentioned in the documentation but had not been implemented.
2445 (This option is not yet really useful because even the additional
2446 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
2449 *) Initial DSO code added into libcrypto for letting OpenSSL (and
2450 OpenSSL-based applications) load shared libraries and bind to
2451 them in a portable way.
2452 [Geoff Thorpe, with contributions from Richard Levitte]
2454 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
2456 *) Make sure _lrotl and _lrotr are only used with MSVC.
2458 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
2459 (the default implementation of RAND_status).
2461 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
2462 to '-clrext' (= clear extensions), as intended and documented.
2463 [Bodo Moeller; inconsistency pointed out by Michael Attili
2466 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
2467 was larger than the MD block size.
2468 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
2470 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
2471 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
2472 using the passed key: if the passed key was a private key the result
2473 of X509_print(), for example, would be to print out all the private key
2477 *) des_quad_cksum() byte order bug fix.
2478 [Ulf Möller, using the problem description in krb4-0.9.7, where
2479 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
2481 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
2483 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
2485 *) For easily testing in shell scripts whether some command
2486 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
2487 returns with exit code 0 iff no command of the given name is available.
2488 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
2489 the output goes to stdout and nothing is printed to stderr.
2490 Additional arguments are always ignored.
2492 Since for each cipher there is a command of the same name,
2493 the 'no-cipher' compilation switches can be tested this way.
2495 ('openssl no-XXX' is not able to detect pseudo-commands such
2496 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
2499 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
2502 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
2503 is set; it will be thrown away anyway because each handshake creates
2505 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
2506 to parameters -- in previous versions (since OpenSSL 0.9.3) the
2507 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
2508 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
2511 *) New s_client option -ign_eof: EOF at stdin is ignored, and
2512 'Q' and 'R' lose their special meanings (quit/renegotiate).
2513 This is part of what -quiet does; unlike -quiet, -ign_eof
2514 does not suppress any output.
2517 *) Add compatibility options to the purpose and trust code. The
2518 purpose X509_PURPOSE_ANY is "any purpose" which automatically
2519 accepts a certificate or CA, this was the previous behaviour,
2520 with all the associated security issues.
2522 X509_TRUST_COMPAT is the old trust behaviour: only and
2523 automatically trust self signed roots in certificate store. A
2524 new trust setting X509_TRUST_DEFAULT is used to specify that
2525 a purpose has no associated trust setting and it should instead
2526 use the value in the default purpose.
2529 *) Fix the PKCS#8 DSA private key code so it decodes keys again
2530 and fix a memory leak.
2533 *) In util/mkerr.pl (which implements 'make errors'), preserve
2534 reason strings from the previous version of the .c file, as
2535 the default to have only downcase letters (and digits) in
2536 automatically generated reasons codes is not always appropriate.
2539 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
2540 using strerror. Previously, ERR_reason_error_string() returned
2541 library names as reason strings for SYSerr; but SYSerr is a special
2542 case where small numbers are errno values, not library numbers.
2545 *) Add '-dsaparam' option to 'openssl dhparam' application. This
2546 converts DSA parameters into DH parameters. (When creating parameters,
2547 DSA_generate_parameters is used.)
2550 *) Include 'length' (recommended exponent length) in C code generated
2551 by 'openssl dhparam -C'.
2554 *) The second argument to set_label in perlasm was already being used
2555 so couldn't be used as a "file scope" flag. Moved to third argument
2559 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
2560 instead of RAND_bytes for encryption IVs and salts.
2563 *) Include RAND_status() into RAND_METHOD instead of implementing
2564 it only for md_rand.c Otherwise replacing the PRNG by calling
2565 RAND_set_rand_method would be impossible.
2568 *) Don't let DSA_generate_key() enter an infinite loop if the random
2569 number generation fails.
2572 *) New 'rand' application for creating pseudo-random output.
2575 *) Added configuration support for Linux/IA64
2576 [Rolf Haberrecker <rolf@suse.de>]
2578 *) Assembler module support for Mingw32.
2581 *) Shared library support for HPUX (in shlib/).
2582 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
2584 *) Shared library support for Solaris gcc.
2585 [Lutz Behnke <behnke@trustcenter.de>]
2587 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
2589 *) PKCS7_encrypt() was adding text MIME headers twice because they
2590 were added manually and by SMIME_crlf_copy().
2593 *) In bntest.c don't call BN_rand with zero bits argument.
2594 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
2596 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
2597 case was implemented. This caused BN_div_recp() to fail occasionally.
2600 *) Add an optional second argument to the set_label() in the perl
2601 assembly language builder. If this argument exists and is set
2602 to 1 it signals that the assembler should use a symbol whose
2603 scope is the entire file, not just the current function. This
2604 is needed with MASM which uses the format label:: for this scope.
2605 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
2607 *) Change the ASN1 types so they are typedefs by default. Before
2608 almost all types were #define'd to ASN1_STRING which was causing
2609 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
2613 *) Change names of new functions to the new get1/get0 naming
2614 convention: After 'get1', the caller owns a reference count
2615 and has to call ..._free; 'get0' returns a pointer to some
2616 data structure without incrementing reference counters.
2617 (Some of the existing 'get' functions increment a reference
2618 counter, some don't.)
2619 Similarly, 'set1' and 'add1' functions increase reference
2620 counters or duplicate objects.
2623 *) Allow for the possibility of temp RSA key generation failure:
2624 the code used to assume it always worked and crashed on failure.
2627 *) Fix potential buffer overrun problem in BIO_printf().
2628 [Ulf Möller, using public domain code by Patrick Powell; problem
2629 pointed out by David Sacerdote <das33@cornell.edu>]
2631 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
2632 RAND_egd() and RAND_status(). In the command line application,
2633 the EGD socket can be specified like a seed file using RANDFILE
2637 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
2638 Some CAs (e.g. Verisign) distribute certificates in this form.
2641 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
2642 list to exclude them. This means that no special compilation option
2643 is needed to use anonymous DH: it just needs to be included in the
2647 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
2648 EVP_MD_type. The old functionality is available in a new macro called
2649 EVP_MD_md(). Change code that uses it and update docs.
2652 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
2653 where the 'void *' argument is replaced by a function pointer argument.
2654 Previously 'void *' was abused to point to functions, which works on
2655 many platforms, but is not correct. As these functions are usually
2656 called by macros defined in OpenSSL header files, most source code
2657 should work without changes.
2660 *) <openssl/opensslconf.h> (which is created by Configure) now contains
2661 sections with information on -D... compiler switches used for
2662 compiling the library so that applications can see them. To enable
2663 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
2664 must be defined. E.g.,
2665 #define OPENSSL_ALGORITHM_DEFINES
2666 #include <openssl/opensslconf.h>
2667 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
2668 [Richard Levitte, Ulf and Bodo Möller]
2670 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
2674 *) Change the 'other' type in certificate aux info to a STACK_OF
2675 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
2676 the required ASN1 format: arbitrary types determined by an OID.
2679 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
2680 argument to 'req'. This is not because the function is newer or
2681 better than others it just uses the work 'NEW' in the certificate
2682 request header lines. Some software needs this.
2685 *) Reorganise password command line arguments: now passwords can be
2686 obtained from various sources. Delete the PEM_cb function and make
2687 it the default behaviour: i.e. if the callback is NULL and the
2688 usrdata argument is not NULL interpret it as a null terminated pass
2689 phrase. If usrdata and the callback are NULL then the pass phrase
2690 is prompted for as usual.
2693 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
2694 the support is automatically enabled. The resulting binaries will
2695 autodetect the card and use it if present.
2696 [Ben Laurie and Compaq Inc.]
2698 *) Work around for Netscape hang bug. This sends certificate request
2699 and server done in one record. Since this is perfectly legal in the
2700 SSL/TLS protocol it isn't a "bug" option and is on by default. See
2701 the bugs/SSLv3 entry for more info.
2704 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
2707 *) Add -rand argument to smime and pkcs12 applications and read/write
2711 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
2714 *) Add command line password options to the remaining applications.
2717 *) Bug fix for BN_div_recp() for numerators with an even number of
2721 *) More tests in bntest.c, and changed test_bn output.
2724 *) ./config recognizes MacOS X now.
2727 *) Bug fix for BN_div() when the first words of num and divsor are
2728 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
2731 *) Add support for various broken PKCS#8 formats, and command line
2732 options to produce them.
2735 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
2736 get temporary BIGNUMs from a BN_CTX.
2739 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
2743 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
2744 include a #define from the old name to the new. The original intent
2745 was that statically linked binaries could for example just call
2746 SSLeay_add_all_ciphers() to just add ciphers to the table and not
2747 link with digests. This never worked becayse SSLeay_add_all_digests()
2748 and SSLeay_add_all_ciphers() were in the same source file so calling
2749 one would link with the other. They are now in separate source files.
2752 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
2755 *) Use a less unusual form of the Miller-Rabin primality test (it used
2756 a binary algorithm for exponentiation integrated into the Miller-Rabin
2757 loop, our standard modexp algorithms are faster).
2760 *) Support for the EBCDIC character set completed.
2761 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
2763 *) Source code cleanups: use const where appropriate, eliminate casts,
2764 use void * instead of char * in lhash.
2767 *) Bugfix: ssl3_send_server_key_exchange was not restartable
2768 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
2769 this the server could overwrite ephemeral keys that the client
2773 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
2774 using 50 iterations of the Rabin-Miller test.
2776 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
2777 iterations of the Rabin-Miller test as required by the appendix
2778 to FIPS PUB 186[-1]) instead of DSA_is_prime.
2779 As BN_is_prime_fasttest includes trial division, DSA parameter
2780 generation becomes much faster.
2782 This implies a change for the callback functions in DSA_is_prime
2783 and DSA_generate_parameters: The callback function is called once
2784 for each positive witness in the Rabin-Miller test, not just
2785 occasionally in the inner loop; and the parameters to the
2786 callback function now provide an iteration count for the outer
2787 loop rather than for the current invocation of the inner loop.
2788 DSA_generate_parameters additionally can call the callback
2789 function with an 'iteration count' of -1, meaning that a
2790 candidate has passed the trial division test (when q is generated
2791 from an application-provided seed, trial division is skipped).
2794 *) New function BN_is_prime_fasttest that optionally does trial
2795 division before starting the Rabin-Miller test and has
2796 an additional BN_CTX * argument (whereas BN_is_prime always
2797 has to allocate at least one BN_CTX).
2798 'callback(1, -1, cb_arg)' is called when a number has passed the
2799 trial division stage.
2802 *) Fix for bug in CRL encoding. The validity dates weren't being handled
2806 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
2809 *) New function BN_pseudo_rand().
2812 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
2813 bignum version of BN_from_montgomery() with the working code from
2814 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
2818 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
2819 made it impossible to use the same SSL_SESSION data structure in
2820 SSL2 clients in multiple threads.
2823 *) The return value of RAND_load_file() no longer counts bytes obtained
2824 by stat(). RAND_load_file(..., -1) is new and uses the complete file
2825 to seed the PRNG (previously an explicit byte count was required).
2826 [Ulf Möller, Bodo Möller]
2828 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
2829 used (char *) instead of (void *) and had casts all over the place.
2832 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
2835 *) Retain source code compatibility for BN_prime_checks macro:
2836 BN_is_prime(..., BN_prime_checks, ...) now uses
2837 BN_prime_checks_for_size to determine the appropriate number of
2838 Rabin-Miller iterations.
2841 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
2842 DH_CHECK_P_NOT_SAFE_PRIME.
2843 (Check if this is true? OpenPGP calls them "strong".)
2846 *) Merge the functionality of "dh" and "gendh" programs into a new program
2847 "dhparam". The old programs are retained for now but will handle DH keys
2848 (instead of parameters) in future.
2851 *) Make the ciphers, s_server and s_client programs check the return values
2852 when a new cipher list is set.
2855 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
2856 ciphers. Before when the 56bit ciphers were enabled the sorting was
2859 The syntax for the cipher sorting has been extended to support sorting by
2860 cipher-strength (using the strength_bits hard coded in the tables).
2861 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
2863 Fix a bug in the cipher-command parser: when supplying a cipher command
2864 string with an "undefined" symbol (neither command nor alphanumeric
2865 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
2866 an error is flagged.
2868 Due to the strength-sorting extension, the code of the
2869 ssl_create_cipher_list() function was completely rearranged. I hope that
2870 the readability was also increased :-)
2871 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
2873 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
2874 for the first serial number and places 2 in the serial number file. This
2875 avoids problems when the root CA is created with serial number zero and
2876 the first user certificate has the same issuer name and serial number
2880 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
2881 the new code. Add documentation for this stuff.
2884 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
2885 X509_*() to X509at_*() on the grounds that they don't handle X509
2886 structures and behave in an analagous way to the X509v3 functions:
2887 they shouldn't be called directly but wrapper functions should be used
2890 So we also now have some wrapper functions that call the X509at functions
2891 when passed certificate requests. (TO DO: similar things can be done with
2892 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
2893 things. Some of these need some d2i or i2d and print functionality
2894 because they handle more complex structures.)
2897 *) Add missing #ifndefs that caused missing symbols when building libssl
2898 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
2899 NO_RSA in ssl/s2*.c.
2900 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
2902 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
2903 has a return value which indicates the quality of the random data
2904 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
2905 error queue. New function RAND_pseudo_bytes() generates output that is
2906 guaranteed to be unique but not unpredictable. RAND_add is like
2907 RAND_seed, but takes an extra argument for an entropy estimate
2908 (RAND_seed always assumes full entropy).
2911 *) Do more iterations of Rabin-Miller probable prime test (specifically,
2912 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
2913 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
2914 in crypto/bn/bn_prime.c for the complete table). This guarantees a
2915 false-positive rate of at most 2^-80 for random input.
2918 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
2921 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
2922 in the 0.9.5 release), this returns the chain
2923 from an X509_CTX structure with a dup of the stack and all
2924 the X509 reference counts upped: so the stack will exist
2925 after X509_CTX_cleanup() has been called. Modify pkcs12.c
2928 Also make SSL_SESSION_print() print out the verify return
2932 *) Add manpage for the pkcs12 command. Also change the default
2933 behaviour so MAC iteration counts are used unless the new
2934 -nomaciter option is used. This improves file security and
2935 only older versions of MSIE (4.0 for example) need it.
2938 *) Honor the no-xxx Configure options when creating .DEF files.
2941 *) Add PKCS#10 attributes to field table: challengePassword,
2942 unstructuredName and unstructuredAddress. These are taken from
2943 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
2944 international characters are used.
2946 More changes to X509_ATTRIBUTE code: allow the setting of types
2947 based on strings. Remove the 'loc' parameter when adding
2948 attributes because these will be a SET OF encoding which is sorted
2952 *) Initial changes to the 'req' utility to allow request generation
2953 automation. This will allow an application to just generate a template
2954 file containing all the field values and have req construct the
2957 Initial support for X509_ATTRIBUTE handling. Stacks of these are
2958 used all over the place including certificate requests and PKCS#7
2959 structures. They are currently handled manually where necessary with
2960 some primitive wrappers for PKCS#7. The new functions behave in a
2961 manner analogous to the X509 extension functions: they allow
2962 attributes to be looked up by NID and added.
2964 Later something similar to the X509V3 code would be desirable to
2965 automatically handle the encoding, decoding and printing of the
2966 more complex types. The string types like challengePassword can
2967 be handled by the string table functions.
2969 Also modified the multi byte string table handling. Now there is
2970 a 'global mask' which masks out certain types. The table itself
2971 can use the flag STABLE_NO_MASK to ignore the mask setting: this
2972 is useful when for example there is only one permissible type
2973 (as in countryName) and using the mask might result in no valid
2977 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
2978 SSL_get_peer_finished to allow applications to obtain the latest
2979 Finished messages sent to the peer or expected from the peer,
2980 respectively. (SSL_get_peer_finished is usually the Finished message
2981 actually received from the peer, otherwise the protocol will be aborted.)
2983 As the Finished message are message digests of the complete handshake
2984 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
2985 be used for external authentication procedures when the authentication
2986 provided by SSL/TLS is not desired or is not enough.
2989 *) Enhanced support for Alpha Linux is added. Now ./config checks if
2990 the host supports BWX extension and if Compaq C is present on the
2991 $PATH. Just exploiting of the BWX extension results in 20-30%
2992 performance kick for some algorithms, e.g. DES and RC4 to mention
2993 a couple. Compaq C in turn generates ~20% faster code for MD5 and
2997 *) Add support for MS "fast SGC". This is arguably a violation of the
2998 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
2999 weak crypto and after checking the certificate is SGC a second one
3000 with strong crypto. MS SGC stops the first handshake after receiving
3001 the server certificate message and sends a second client hello. Since
3002 a server will typically do all the time consuming operations before
3003 expecting any further messages from the client (server key exchange
3004 is the most expensive) there is little difference between the two.
3006 To get OpenSSL to support MS SGC we have to permit a second client
3007 hello message after we have sent server done. In addition we have to
3008 reset the MAC if we do get this second client hello.
3011 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
3012 if a DER encoded private key is RSA or DSA traditional format. Changed
3013 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
3014 format DER encoded private key. Newer code should use PKCS#8 format which
3015 has the key type encoded in the ASN1 structure. Added DER private key
3016 support to pkcs8 application.
3019 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
3020 ciphersuites has been selected (as required by the SSL 3/TLS 1
3021 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
3022 is set, we interpret this as a request to violate the specification
3023 (the worst that can happen is a handshake failure, and 'correct'
3024 behaviour would result in a handshake failure anyway).
3027 *) In SSL_CTX_add_session, take into account that there might be multiple
3028 SSL_SESSION structures with the same session ID (e.g. when two threads
3029 concurrently obtain them from an external cache).
3030 The internal cache can handle only one SSL_SESSION with a given ID,
3031 so if there's a conflict, we now throw out the old one to achieve
3035 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
3036 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
3037 some routines that use cipher OIDs: some ciphers do not have OIDs
3038 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
3042 *) Simplify the trust setting structure and code. Now we just have
3043 two sequences of OIDs for trusted and rejected settings. These will
3044 typically have values the same as the extended key usage extension
3045 and any application specific purposes.
3047 The trust checking code now has a default behaviour: it will just
3048 check for an object with the same NID as the passed id. Functions can
3049 be provided to override either the default behaviour or the behaviour
3050 for a given id. SSL client, server and email already have functions
3051 in place for compatibility: they check the NID and also return "trusted"
3052 if the certificate is self signed.
3055 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
3056 traditional format into an EVP_PKEY structure.
3059 *) Add a password callback function PEM_cb() which either prompts for
3060 a password if usr_data is NULL or otherwise assumes it is a null
3061 terminated password. Allow passwords to be passed on command line
3062 environment or config files in a few more utilities.
3065 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
3066 keys. Add some short names for PKCS#8 PBE algorithms and allow them
3067 to be specified on the command line for the pkcs8 and pkcs12 utilities.
3068 Update documentation.
3071 *) Support for ASN1 "NULL" type. This could be handled before by using
3072 ASN1_TYPE but there wasn't any function that would try to read a NULL
3073 and produce an error if it couldn't. For compatibility we also have
3074 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
3075 don't allocate anything because they don't need to.
3078 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
3080 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
3082 *) Rebuild of the memory allocation routines used by OpenSSL code and
3083 possibly others as well. The purpose is to make an interface that
3084 provide hooks so anyone can build a separate set of allocation and
3085 deallocation routines to be used by OpenSSL, for example memory
3086 pool implementations, or something else, which was previously hard
3087 since Malloc(), Realloc() and Free() were defined as macros having
3088 the values malloc, realloc and free, respectively (except for Win32
3089 compilations). The same is provided for memory debugging code.
3090 OpenSSL already comes with functionality to find memory leaks, but
3091 this gives people a chance to debug other memory problems.
3093 With these changes, a new set of functions and macros have appeared:
3095 CRYPTO_set_mem_debug_functions() [F]
3096 CRYPTO_get_mem_debug_functions() [F]
3097 CRYPTO_dbg_set_options() [F]
3098 CRYPTO_dbg_get_options() [F]
3099 CRYPTO_malloc_debug_init() [M]
3101 The memory debug functions are NULL by default, unless the library
3102 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
3103 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
3104 gives the standard debugging functions that come with OpenSSL) or
3105 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
3106 provided by the library user) must be used. When the standard
3107 debugging functions are used, CRYPTO_dbg_set_options can be used to
3108 request additional information:
3109 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
3110 the CRYPTO_MDEBUG_xxx macro when compiling the library.
3112 Also, things like CRYPTO_set_mem_functions will always give the
3113 expected result (the new set of functions is used for allocation
3114 and deallocation) at all times, regardless of platform and compiler
3117 To finish it up, some functions that were never use in any other
3118 way than through macros have a new API and new semantic:
3121 CRYPTO_dbg_realloc()
3124 All macros of value have retained their old syntax.
3125 [Richard Levitte and Bodo Moeller]
3127 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
3128 ordering of SMIMECapabilities wasn't in "strength order" and there
3129 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
3133 *) Some ASN1 types with illegal zero length encoding (INTEGER,
3134 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
3135 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
3137 *) Merge in my S/MIME library for OpenSSL. This provides a simple
3138 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
3139 functionality to handle multipart/signed properly) and a utility
3140 called 'smime' to call all this stuff. This is based on code I
3141 originally wrote for Celo who have kindly allowed it to be
3142 included in OpenSSL.
3145 *) Add variants des_set_key_checked and des_set_key_unchecked of
3146 des_set_key (aka des_key_sched). Global variable des_check_key
3147 decides which of these is called by des_set_key; this way
3148 des_check_key behaves as it always did, but applications and
3149 the library itself, which was buggy for des_check_key == 1,
3150 have a cleaner way to pick the version they need.
3153 *) New function PKCS12_newpass() which changes the password of a
3157 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
3158 dynamic mix. In both cases the ids can be used as an index into the
3159 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
3160 functions so they accept a list of the field values and the
3161 application doesn't need to directly manipulate the X509_TRUST
3165 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
3169 *) Modify the way the V3 extension code looks up extensions. This now
3170 works in a similar way to the object code: we have some "standard"
3171 extensions in a static table which is searched with OBJ_bsearch()
3172 and the application can add dynamic ones if needed. The file
3173 crypto/x509v3/ext_dat.h now has the info: this file needs to be
3174 updated whenever a new extension is added to the core code and kept
3175 in ext_nid order. There is a simple program 'tabtest.c' which checks
3176 this. New extensions are not added too often so this file can readily
3177 be maintained manually.
3179 There are two big advantages in doing things this way. The extensions
3180 can be looked up immediately and no longer need to be "added" using
3181 X509V3_add_standard_extensions(): this function now does nothing.
3182 [Side note: I get *lots* of email saying the extension code doesn't
3183 work because people forget to call this function]
3184 Also no dynamic allocation is done unless new extensions are added:
3185 so if we don't add custom extensions there is no need to call
3186 X509V3_EXT_cleanup().
3189 *) Modify enc utility's salting as follows: make salting the default. Add a
3190 magic header, so unsalted files fail gracefully instead of just decrypting
3191 to garbage. This is because not salting is a big security hole, so people
3192 should be discouraged from doing it.
3195 *) Fixes and enhancements to the 'x509' utility. It allowed a message
3196 digest to be passed on the command line but it only used this
3197 parameter when signing a certificate. Modified so all relevant
3198 operations are affected by the digest parameter including the
3199 -fingerprint and -x509toreq options. Also -x509toreq choked if a
3200 DSA key was used because it didn't fix the digest.
3203 *) Initial certificate chain verify code. Currently tests the untrusted
3204 certificates for consistency with the verify purpose (which is set
3205 when the X509_STORE_CTX structure is set up) and checks the pathlength.
3207 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
3208 this is because it will reject chains with invalid extensions whereas
3209 every previous version of OpenSSL and SSLeay made no checks at all.
3211 Trust code: checks the root CA for the relevant trust settings. Trust
3212 settings have an initial value consistent with the verify purpose: e.g.
3213 if the verify purpose is for SSL client use it expects the CA to be
3214 trusted for SSL client use. However the default value can be changed to
3215 permit custom trust settings: one example of this would be to only trust
3216 certificates from a specific "secure" set of CAs.
3218 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
3219 which should be used for version portability: especially since the
3220 verify structure is likely to change more often now.
3222 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
3223 to set them. If not set then assume SSL clients will verify SSL servers
3226 Two new options to the verify program: -untrusted allows a set of
3227 untrusted certificates to be passed in and -purpose which sets the
3228 intended purpose of the certificate. If a purpose is set then the
3229 new chain verify code is used to check extension consistency.
3232 *) Support for the authority information access extension.
3235 *) Modify RSA and DSA PEM read routines to transparently handle
3236 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
3237 public keys in a format compatible with certificate
3238 SubjectPublicKeyInfo structures. Unfortunately there were already
3239 functions called *_PublicKey_* which used various odd formats so
3240 these are retained for compatibility: however the DSA variants were
3241 never in a public release so they have been deleted. Changed dsa/rsa
3242 utilities to handle the new format: note no releases ever handled public
3243 keys so we should be OK.
3245 The primary motivation for this change is to avoid the same fiasco
3246 that dogs private keys: there are several incompatible private key
3247 formats some of which are standard and some OpenSSL specific and
3248 require various evil hacks to allow partial transparent handling and
3249 even then it doesn't work with DER formats. Given the option anything
3250 other than PKCS#8 should be dumped: but the other formats have to
3251 stay in the name of compatibility.
3253 With public keys and the benefit of hindsight one standard format
3254 is used which works with EVP_PKEY, RSA or DSA structures: though
3255 it clearly returns an error if you try to read the wrong kind of key.
3257 Added a -pubkey option to the 'x509' utility to output the public key.
3258 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
3259 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
3260 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
3261 that do the same as the EVP_PKEY_assign_*() except they up the
3262 reference count of the added key (they don't "swallow" the
3266 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
3267 CRLs would fail if the file contained no certificates or no CRLs:
3268 added a new function to read in both types and return the number
3269 read: this means that if none are read it will be an error. The
3270 DER versions of the certificate and CRL reader would always fail
3271 because it isn't possible to mix certificates and CRLs in DER format
3272 without choking one or the other routine. Changed this to just read
3273 a certificate: this is the best we can do. Also modified the code
3274 in apps/verify.c to take notice of return codes: it was previously
3275 attempting to read in certificates from NULL pointers and ignoring
3276 any errors: this is one reason why the cert and CRL reader seemed
3277 to work. It doesn't check return codes from the default certificate
3278 routines: these may well fail if the certificates aren't installed.
3281 *) Code to support otherName option in GeneralName.
3284 *) First update to verify code. Change the verify utility
3285 so it warns if it is passed a self signed certificate:
3286 for consistency with the normal behaviour. X509_verify
3287 has been modified to it will now verify a self signed
3288 certificate if *exactly* the same certificate appears
3289 in the store: it was previously impossible to trust a
3290 single self signed certificate. This means that:
3291 openssl verify ss.pem
3292 now gives a warning about a self signed certificate but
3293 openssl verify -CAfile ss.pem ss.pem
3297 *) For servers, store verify_result in SSL_SESSION data structure
3298 (and add it to external session representation).
3299 This is needed when client certificate verifications fails,
3300 but an application-provided verification callback (set by
3301 SSL_CTX_set_cert_verify_callback) allows accepting the session
3302 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
3303 but returns 1): When the session is reused, we have to set
3304 ssl->verify_result to the appropriate error code to avoid
3306 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
3308 *) Fix a bug in the new PKCS#7 code: it didn't consider the
3309 case in PKCS7_dataInit() where the signed PKCS7 structure
3310 didn't contain any existing data because it was being created.
3311 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
3313 *) Add a salt to the key derivation routines in enc.c. This
3314 forms the first 8 bytes of the encrypted file. Also add a
3315 -S option to allow a salt to be input on the command line.
3318 *) New function X509_cmp(). Oddly enough there wasn't a function
3319 to compare two certificates. We do this by working out the SHA1
3320 hash and comparing that. X509_cmp() will be needed by the trust
3324 *) SSL_get1_session() is like SSL_get_session(), but increments
3325 the reference count in the SSL_SESSION returned.
3326 [Geoff Thorpe <geoff@eu.c2.net>]
3328 *) Fix for 'req': it was adding a null to request attributes.
3329 Also change the X509_LOOKUP and X509_INFO code to handle
3330 certificate auxiliary information.
3333 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
3337 *) Add the possibility to add extra information to the memory leak
3338 detecting output, to form tracebacks, showing from where each
3339 allocation was originated: CRYPTO_push_info("constant string") adds
3340 the string plus current file name and line number to a per-thread
3341 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
3342 is like calling CYRPTO_pop_info() until the stack is empty.
3343 Also updated memory leak detection code to be multi-thread-safe.
3346 *) Add options -text and -noout to pkcs7 utility and delete the
3347 encryption options which never did anything. Update docs.
3350 *) Add options to some of the utilities to allow the pass phrase
3351 to be included on either the command line (not recommended on
3352 OSes like Unix) or read from the environment. Update the
3353 manpages and fix a few bugs.
3356 *) Add a few manpages for some of the openssl commands.
3359 *) Fix the -revoke option in ca. It was freeing up memory twice,
3360 leaking and not finding already revoked certificates.
3363 *) Extensive changes to support certificate auxiliary information.
3364 This involves the use of X509_CERT_AUX structure and X509_AUX
3365 functions. An X509_AUX function such as PEM_read_X509_AUX()
3366 can still read in a certificate file in the usual way but it
3367 will also read in any additional "auxiliary information". By
3368 doing things this way a fair degree of compatibility can be
3369 retained: existing certificates can have this information added
3370 using the new 'x509' options.
3372 Current auxiliary information includes an "alias" and some trust
3373 settings. The trust settings will ultimately be used in enhanced
3374 certificate chain verification routines: currently a certificate
3375 can only be trusted if it is self signed and then it is trusted
3379 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
3380 The problem was that one of the replacement routines had not been working
3381 since SSLeay releases. For now the offending routine has been replaced
3382 with non-optimised assembler. Even so, this now gives around 95%
3383 performance improvement for 1024 bit RSA signs.
3386 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
3387 handling. Most clients have the effective key size in bits equal to
3388 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
3389 A few however don't do this and instead use the size of the decrypted key
3390 to determine the RC2 key length and the AlgorithmIdentifier to determine
3391 the effective key length. In this case the effective key length can still
3392 be 40 bits but the key length can be 168 bits for example. This is fixed
3393 by manually forcing an RC2 key into the EVP_PKEY structure because the
3394 EVP code can't currently handle unusual RC2 key sizes: it always assumes
3395 the key length and effective key length are equal.
3398 *) Add a bunch of functions that should simplify the creation of
3399 X509_NAME structures. Now you should be able to do:
3400 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
3401 and have it automatically work out the correct field type and fill in
3402 the structures. The more adventurous can try:
3403 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
3404 and it will (hopefully) work out the correct multibyte encoding.
3407 *) Change the 'req' utility to use the new field handling and multibyte
3408 copy routines. Before the DN field creation was handled in an ad hoc
3409 way in req, ca, and x509 which was rather broken and didn't support
3410 BMPStrings or UTF8Strings. Since some software doesn't implement
3411 BMPStrings or UTF8Strings yet, they can be enabled using the config file
3412 using the dirstring_type option. See the new comment in the default
3413 openssl.cnf for more info.
3416 *) Make crypto/rand/md_rand.c more robust:
3417 - Assure unique random numbers after fork().
3418 - Make sure that concurrent threads access the global counter and
3419 md serializably so that we never lose entropy in them
3420 or use exactly the same state in multiple threads.
3421 Access to the large state is not always serializable because
3422 the additional locking could be a performance killer, and
3423 md should be large enough anyway.
3426 *) New file apps/app_rand.c with commonly needed functionality
3427 for handling the random seed file.
3429 Use the random seed file in some applications that previously did not:
3431 dsaparam -genkey (which also ignored its '-rand' option),
3434 x509 (when signing).
3435 Except on systems with /dev/urandom, it is crucial to have a random
3436 seed file at least for key creation, DSA signing, and for DH exchanges;
3437 for RSA signatures we could do without one.
3439 gendh and gendsa (unlike genrsa) used to read only the first byte
3440 of each file listed in the '-rand' option. The function as previously
3441 found in genrsa is now in app_rand.c and is used by all programs
3442 that support '-rand'.
3445 *) In RAND_write_file, use mode 0600 for creating files;
3446 don't just chmod when it may be too late.
3449 *) Report an error from X509_STORE_load_locations
3450 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
3453 *) New function ASN1_mbstring_copy() this copies a string in either
3454 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
3455 into an ASN1_STRING type. A mask of permissible types is passed
3456 and it chooses the "minimal" type to use or an error if not type
3460 *) Add function equivalents to the various macros in asn1.h. The old
3461 macros are retained with an M_ prefix. Code inside the library can
3462 use the M_ macros. External code (including the openssl utility)
3463 should *NOT* in order to be "shared library friendly".
3466 *) Add various functions that can check a certificate's extensions
3467 to see if it usable for various purposes such as SSL client,
3468 server or S/MIME and CAs of these types. This is currently
3469 VERY EXPERIMENTAL but will ultimately be used for certificate chain
3470 verification. Also added a -purpose flag to x509 utility to
3471 print out all the purposes.
3474 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
3478 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
3479 for, obtain and decode and extension and obtain its critical flag.
3480 This allows all the necessary extension code to be handled in a
3481 single function call.
3484 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
3485 platforms. See crypto/rc4/rc4_enc.c for further details.
3488 *) New -noout option to asn1parse. This causes no output to be produced
3489 its main use is when combined with -strparse and -out to extract data
3490 from a file (which may not be in ASN.1 format).
3493 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
3494 when producing the local key id.
3495 [Richard Levitte <levitte@stacken.kth.se>]
3497 *) New option -dhparam in s_server. This allows a DH parameter file to be
3498 stated explicitly. If it is not stated then it tries the first server
3499 certificate file. The previous behaviour hard coded the filename
3503 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
3504 a public key to be input or output. For example:
3505 openssl rsa -in key.pem -pubout -out pubkey.pem
3506 Also added necessary DSA public key functions to handle this.
3509 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
3510 in the message. This was handled by allowing
3511 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
3512 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
3514 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
3515 to the end of the strings whereas this didn't. This would cause problems
3516 if strings read with d2i_ASN1_bytes() were later modified.
3517 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
3519 *) Fix for base64 decode bug. When a base64 bio reads only one line of
3520 data and it contains EOF it will end up returning an error. This is
3521 caused by input 46 bytes long. The cause is due to the way base64
3522 BIOs find the start of base64 encoded data. They do this by trying a
3523 trial decode on each line until they find one that works. When they
3524 do a flag is set and it starts again knowing it can pass all the
3525 data directly through the decoder. Unfortunately it doesn't reset
3526 the context it uses. This means that if EOF is reached an attempt
3527 is made to pass two EOFs through the context and this causes the
3528 resulting error. This can also cause other problems as well. As is
3529 usual with these problems it takes *ages* to find and the fix is
3530 trivial: move one line.
3531 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
3533 *) Ugly workaround to get s_client and s_server working under Windows. The
3534 old code wouldn't work because it needed to select() on sockets and the
3535 tty (for keypresses and to see if data could be written). Win32 only
3536 supports select() on sockets so we select() with a 1s timeout on the
3537 sockets and then see if any characters are waiting to be read, if none
3538 are present then we retry, we also assume we can always write data to
3539 the tty. This isn't nice because the code then blocks until we've
3540 received a complete line of data and it is effectively polling the
3541 keyboard at 1s intervals: however it's quite a bit better than not
3542 working at all :-) A dedicated Windows application might handle this
3543 with an event loop for example.
3546 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
3547 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
3548 will be called when RSA_sign() and RSA_verify() are used. This is useful
3549 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
3550 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
3551 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
3552 This necessitated the support of an extra signature type NID_md5_sha1
3553 for SSL signatures and modifications to the SSL library to use it instead
3554 of calling RSA_public_decrypt() and RSA_private_encrypt().
3557 *) Add new -verify -CAfile and -CApath options to the crl program, these
3558 will lookup a CRL issuers certificate and verify the signature in a
3559 similar way to the verify program. Tidy up the crl program so it
3560 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
3561 less strict. It will now permit CRL extensions even if it is not
3562 a V2 CRL: this will allow it to tolerate some broken CRLs.
3565 *) Initialize all non-automatic variables each time one of the openssl
3566 sub-programs is started (this is necessary as they may be started
3567 multiple times from the "OpenSSL>" prompt).
3568 [Lennart Bang, Bodo Moeller]
3570 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
3571 removing all other RSA functionality (this is what NO_RSA does). This
3572 is so (for example) those in the US can disable those operations covered
3573 by the RSA patent while allowing storage and parsing of RSA keys and RSA
3577 *) Non-copying interface to BIO pairs.
3578 (still largely untested)
3581 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
3582 ASCII string. This was handled independently in various places before.
3585 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
3586 UTF8 strings a character at a time.
3589 *) Use client_version from client hello to select the protocol
3590 (s23_srvr.c) and for RSA client key exchange verification
3591 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
3594 *) Add various utility functions to handle SPKACs, these were previously
3595 handled by poking round in the structure internals. Added new function
3596 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
3597 print, verify and generate SPKACs. Based on an original idea from
3598 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
3601 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
3604 *) Allow the config file extension section to be overwritten on the
3605 command line. Based on an original idea from Massimiliano Pala
3606 <madwolf@comune.modena.it>. The new option is called -extensions
3607 and can be applied to ca, req and x509. Also -reqexts to override
3608 the request extensions in req and -crlexts to override the crl extensions
3612 *) Add new feature to the SPKAC handling in ca. Now you can include
3613 the same field multiple times by preceding it by "XXXX." for example:
3616 this is the same syntax as used in the req config file.
3619 *) Allow certificate extensions to be added to certificate requests. These
3620 are specified in a 'req_extensions' option of the req section of the
3621 config file. They can be printed out with the -text option to req but
3622 are otherwise ignored at present.
3625 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
3626 data read consists of only the final block it would not decrypted because
3627 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
3628 A misplaced 'break' also meant the decrypted final block might not be
3629 copied until the next read.
3632 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
3633 a few extra parameters to the DH structure: these will be useful if
3634 for example we want the value of 'q' or implement X9.42 DH.
3637 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
3638 provides hooks that allow the default DSA functions or functions on a
3639 "per key" basis to be replaced. This allows hardware acceleration and
3640 hardware key storage to be handled without major modification to the
3641 library. Also added low level modexp hooks and CRYPTO_EX structure and
3642 associated functions.
3645 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
3646 as "read only": it can't be written to and the buffer it points to will
3647 not be freed. Reading from a read only BIO is much more efficient than
3648 a normal memory BIO. This was added because there are several times when
3649 an area of memory needs to be read from a BIO. The previous method was
3650 to create a memory BIO and write the data to it, this results in two
3651 copies of the data and an O(n^2) reading algorithm. There is a new
3652 function BIO_new_mem_buf() which creates a read only memory BIO from
3653 an area of memory. Also modified the PKCS#7 routines to use read only
3657 *) Bugfix: ssl23_get_client_hello did not work properly when called in
3658 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
3659 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
3660 but a retry condition occured while trying to read the rest.
3663 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
3664 NID_pkcs7_encrypted by default: this was wrong since this should almost
3665 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
3666 the encrypted data type: this is a more sensible place to put it and it
3667 allows the PKCS#12 code to be tidied up that duplicated this
3671 *) Changed obj_dat.pl script so it takes its input and output files on
3672 the command line. This should avoid shell escape redirection problems
3676 *) Initial support for certificate extension requests, these are included
3677 in things like Xenroll certificate requests. Included functions to allow
3678 extensions to be obtained and added.
3681 *) -crlf option to s_client and s_server for sending newlines as
3682 CRLF (as required by many protocols).
3685 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
3687 *) Install libRSAglue.a when OpenSSL is built with RSAref.
3688 [Ralf S. Engelschall]
3690 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
3691 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
3693 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
3697 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
3698 DH parameters/keys (q is lost during that conversion, but the resulting
3699 DH parameters contain its length).
3701 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
3702 much faster than DH_generate_parameters (which creates parameters
3703 where p = 2*q + 1), and also the smaller q makes DH computations
3704 much more efficient (160-bit exponentiation instead of 1024-bit
3705 exponentiation); so this provides a convenient way to support DHE
3706 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
3707 utter importance to use
3708 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3710 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3711 when such DH parameters are used, because otherwise small subgroup
3712 attacks may become possible!
3715 *) Avoid memory leak in i2d_DHparams.
3718 *) Allow the -k option to be used more than once in the enc program:
3719 this allows the same encrypted message to be read by multiple recipients.
3722 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
3723 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
3724 it will always use the numerical form of the OID, even if it has a short
3728 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
3729 method only got called if p,q,dmp1,dmq1,iqmp components were present,
3730 otherwise bn_mod_exp was called. In the case of hardware keys for example
3731 no private key components need be present and it might store extra data
3732 in the RSA structure, which cannot be accessed from bn_mod_exp.
3733 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
3734 private key operations.
3737 *) Added support for SPARC Linux.
3740 *) pem_password_cb function type incompatibly changed from
3741 typedef int pem_password_cb(char *buf, int size, int rwflag);
3743 ....(char *buf, int size, int rwflag, void *userdata);
3744 so that applications can pass data to their callbacks:
3745 The PEM[_ASN1]_{read,write}... functions and macros now take an
3746 additional void * argument, which is just handed through whenever
3747 the password callback is called.
3748 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
3750 New function SSL_CTX_set_default_passwd_cb_userdata.
3752 Compatibility note: As many C implementations push function arguments
3753 onto the stack in reverse order, the new library version is likely to
3754 interoperate with programs that have been compiled with the old
3755 pem_password_cb definition (PEM_whatever takes some data that
3756 happens to be on the stack as its last argument, and the callback
3757 just ignores this garbage); but there is no guarantee whatsoever that
3760 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
3761 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
3762 problems not only on Windows, but also on some Unix platforms.
3763 To avoid problematic command lines, these definitions are now in an
3764 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
3765 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
3768 *) MIPS III/IV assembler module is reimplemented.
3771 *) More DES library cleanups: remove references to srand/rand and
3772 delete an unused file.
3775 *) Add support for the the free Netwide assembler (NASM) under Win32,
3776 since not many people have MASM (ml) and it can be hard to obtain.
3777 This is currently experimental but it seems to work OK and pass all
3778 the tests. Check out INSTALL.W32 for info.
3781 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
3782 without temporary keys kept an extra copy of the server key,
3783 and connections with temporary keys did not free everything in case
3787 *) New function RSA_check_key and new openssl rsa option -check
3788 for verifying the consistency of RSA keys.
3789 [Ulf Moeller, Bodo Moeller]
3791 *) Various changes to make Win32 compile work:
3792 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
3793 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
3794 comparison" warnings.
3795 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
3798 *) Add a debugging option to PKCS#5 v2 key generation function: when
3799 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
3800 derived keys are printed to stderr.
3803 *) Copy the flags in ASN1_STRING_dup().
3804 [Roman E. Pavlov <pre@mo.msk.ru>]
3806 *) The x509 application mishandled signing requests containing DSA
3807 keys when the signing key was also DSA and the parameters didn't match.
3809 It was supposed to omit the parameters when they matched the signing key:
3810 the verifying software was then supposed to automatically use the CA's
3811 parameters if they were absent from the end user certificate.
3813 Omitting parameters is no longer recommended. The test was also
3814 the wrong way round! This was probably due to unusual behaviour in
3815 EVP_cmp_parameters() which returns 1 if the parameters match.
3816 This meant that parameters were omitted when they *didn't* match and
3817 the certificate was useless. Certificates signed with 'ca' didn't have
3819 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
3821 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
3822 The interface is as follows:
3823 Applications can use
3824 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
3825 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
3826 "off" is now the default.
3827 The library internally uses
3828 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
3829 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
3830 to disable memory-checking temporarily.
3832 Some inconsistent states that previously were possible (and were
3833 even the default) are now avoided.
3835 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
3836 with each memory chunk allocated; this is occasionally more helpful
3837 than just having a counter.
3839 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
3841 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
3845 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
3846 which largely parallels "options", but is for changing API behaviour,
3847 whereas "options" are about protocol behaviour.
3848 Initial "mode" flags are:
3850 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
3851 a single record has been written.
3852 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
3853 retries use the same buffer location.
3854 (But all of the contents must be
3858 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
3861 *) Fix problems with no-hmac etc.
3862 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
3864 *) New functions RSA_get_default_method(), RSA_set_method() and
3865 RSA_get_method(). These allows replacement of RSA_METHODs without having
3866 to mess around with the internals of an RSA structure.
3869 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
3870 Also really enable memory leak checks in openssl.c and in some
3872 [Chad C. Mulligan, Bodo Moeller]
3874 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
3875 up the length of negative integers. This has now been simplified to just
3876 store the length when it is first determined and use it later, rather
3877 than trying to keep track of where data is copied and updating it to
3879 [Steve Henson, reported by Brien Wheeler
3880 <bwheeler@authentica-security.com>]
3882 *) Add a new function PKCS7_signatureVerify. This allows the verification
3883 of a PKCS#7 signature but with the signing certificate passed to the
3884 function itself. This contrasts with PKCS7_dataVerify which assumes the
3885 certificate is present in the PKCS#7 structure. This isn't always the
3886 case: certificates can be omitted from a PKCS#7 structure and be
3887 distributed by "out of band" means (such as a certificate database).
3890 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
3891 function prototypes in pem.h, also change util/mkdef.pl to add the
3892 necessary function names.
3895 *) mk1mf.pl (used by Windows builds) did not properly read the
3896 options set by Configure in the top level Makefile, and Configure
3897 was not even able to write more than one option correctly.
3898 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
3901 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
3902 file to be loaded from a BIO or FILE pointer. The BIO version will
3903 for example allow memory BIOs to contain config info.
3906 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
3907 Whoever hopes to achieve shared-library compatibility across versions
3908 must use this, not the compile-time macro.
3909 (Exercise 0.9.4: Which is the minimum library version required by
3911 Note: All this applies only to multi-threaded programs, others don't
3915 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
3916 through a BIO pair triggered the default case, i.e.
3917 SSLerr(...,SSL_R_UNKNOWN_STATE).
3920 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
3921 can use the SSL library even if none of the specific BIOs is
3925 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
3926 for the encoded length.
3927 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
3929 *) Add initial documentation of the X509V3 functions.
3932 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
3933 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
3934 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
3935 secure PKCS#8 private key format with a high iteration count.
3938 *) Fix determination of Perl interpreter: A perl or perl5
3939 _directory_ in $PATH was also accepted as the interpreter.
3940 [Ralf S. Engelschall]
3942 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
3943 wrong with it but it was very old and did things like calling
3944 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
3948 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
3949 to use the new extension code.
3952 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
3953 with macros. This should make it easier to change their form, add extra
3954 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
3958 *) Add to configuration table a new entry that can specify an alternative
3959 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
3960 according to Mark Crispin <MRC@Panda.COM>.
3964 *) DES CBC did not update the IV. Weird.
3967 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
3968 Changing the behaviour of the former might break existing programs --
3969 where IV updating is needed, des_ncbc_encrypt can be used.
3972 *) When bntest is run from "make test" it drives bc to check its
3973 calculations, as well as internally checking them. If an internal check
3974 fails, it needs to cause bc to give a non-zero result or make test carries
3975 on without noticing the failure. Fixed.
3978 *) DES library cleanups.
3981 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
3982 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
3983 ciphers. NOTE: although the key derivation function has been verified
3984 against some published test vectors it has not been extensively tested
3985 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
3989 *) Instead of "mkdir -p", which is not fully portable, use new
3990 Perl script "util/mkdir-p.pl".
3993 *) Rewrite the way password based encryption (PBE) is handled. It used to
3994 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
3995 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
3996 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
3997 the 'parameter' field of the AlgorithmIdentifier is passed to the
3998 underlying key generation function so it must do its own ASN1 parsing.
3999 This has also changed the EVP_PBE_CipherInit() function which now has a
4000 'parameter' argument instead of literal salt and iteration count values
4001 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
4004 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
4005 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
4006 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
4007 KEY" because this clashed with PKCS#8 unencrypted string. Since this
4008 value was just used as a "magic string" and not used directly its
4009 value doesn't matter.
4012 *) Introduce some semblance of const correctness to BN. Shame C doesn't
4016 *) "linux-sparc64" configuration (ultrapenguin).
4017 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
4018 "linux-sparc" configuration.
4019 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
4021 *) config now generates no-xxx options for missing ciphers.
4024 *) Support the EBCDIC character set (work in progress).
4025 File ebcdic.c not yet included because it has a different license.
4026 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4028 *) Support BS2000/OSD-POSIX.
4029 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4031 *) Make callbacks for key generation use void * instead of char *.
4034 *) Make S/MIME samples compile (not yet tested).
4037 *) Additional typesafe stacks.
4040 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
4044 Changes between 0.9.3 and 0.9.3a [29 May 1999]
4046 *) New configuration variant "sco5-gcc".
4048 *) Updated some demos.
4049 [Sean O Riordain, Wade Scholine]
4051 *) Add missing BIO_free at exit of pkcs12 application.
4054 *) Fix memory leak in conf.c.
4057 *) Updates for Win32 to assembler version of MD5.
4060 *) Set #! path to perl in apps/der_chop to where we found it
4061 instead of using a fixed path.
4064 *) SHA library changes for irix64-mips4-cc.
4067 *) Improvements for VMS support.
4071 Changes between 0.9.2b and 0.9.3 [24 May 1999]
4073 *) Bignum library bug fix. IRIX 6 passes "make test" now!
4074 This also avoids the problems with SC4.2 and unpatched SC5.
4075 [Andy Polyakov <appro@fy.chalmers.se>]
4077 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
4078 These are required because of the typesafe stack would otherwise break
4079 existing code. If old code used a structure member which used to be STACK
4080 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
4081 sk_num or sk_value it would produce an error because the num, data members
4082 are not present in STACK_OF. Now it just produces a warning. sk_set
4083 replaces the old method of assigning a value to sk_value
4084 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
4085 that does this will no longer work (and should use sk_set instead) but
4086 this could be regarded as a "questionable" behaviour anyway.
4089 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
4090 correctly handle encrypted S/MIME data.
4093 *) Change type of various DES function arguments from des_cblock
4094 (which means, in function argument declarations, pointer to char)
4095 to des_cblock * (meaning pointer to array with 8 char elements),
4096 which allows the compiler to do more typechecking; it was like
4097 that back in SSLeay, but with lots of ugly casts.
4099 Introduce new type const_des_cblock.
4102 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
4103 problems: find RecipientInfo structure that matches recipient certificate
4104 and initialise the ASN1 structures properly based on passed cipher.
4107 *) Belatedly make the BN tests actually check the results.
4110 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
4111 to and from BNs: it was completely broken. New compilation option
4112 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
4113 key elements as negative integers.
4116 *) Reorganize and speed up MD5.
4117 [Andy Polyakov <appro@fy.chalmers.se>]
4120 [Richard Levitte <richard@levitte.org>]
4122 *) New option -out to asn1parse to allow the parsed structure to be
4123 output to a file. This is most useful when combined with the -strparse
4124 option to examine the output of things like OCTET STRINGS.
4127 *) Make SSL library a little more fool-proof by not requiring any longer
4128 that SSL_set_{accept,connect}_state be called before
4129 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
4130 in many applications because usually everything *appeared* to work as
4131 intended anyway -- now it really works as intended).
4134 *) Move openssl.cnf out of lib/.
4137 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
4138 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
4139 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
4140 [Ralf S. Engelschall]
4142 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
4143 handle PKCS#7 enveloped data properly.
4144 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
4146 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
4147 copying pointers. The cert_st handling is changed by this in
4148 various ways (and thus what used to be known as ctx->default_cert
4149 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
4150 any longer when s->cert does not give us what we need).
4151 ssl_cert_instantiate becomes obsolete by this change.
4152 As soon as we've got the new code right (possibly it already is?),
4153 we have solved a couple of bugs of the earlier code where s->cert
4154 was used as if it could not have been shared with other SSL structures.
4156 Note that using the SSL API in certain dirty ways now will result
4157 in different behaviour than observed with earlier library versions:
4158 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
4159 does not influence s as it used to.
4161 In order to clean up things more thoroughly, inside SSL_SESSION
4162 we don't use CERT any longer, but a new structure SESS_CERT
4163 that holds per-session data (if available); currently, this is
4164 the peer's certificate chain and, for clients, the server's certificate
4165 and temporary key. CERT holds only those values that can have
4166 meaningful defaults in an SSL_CTX.
4169 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
4170 from the internal representation. Various PKCS#7 fixes: remove some
4171 evil casts and set the enc_dig_alg field properly based on the signing
4175 *) Allow PKCS#12 password to be set from the command line or the
4176 environment. Let 'ca' get its config file name from the environment
4177 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
4181 *) Allow certificate policies extension to use an IA5STRING for the
4182 organization field. This is contrary to the PKIX definition but
4183 VeriSign uses it and IE5 only recognises this form. Document 'x509'
4187 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
4188 without disallowing inline assembler and the like for non-pedantic builds.
4191 *) Support Borland C++ builder.
4192 [Janez Jere <jj@void.si>, modified by Ulf Möller]
4197 *) SHA-1 cleanups and performance enhancements.
4198 [Andy Polyakov <appro@fy.chalmers.se>]
4200 *) Sparc v8plus assembler for the bignum library.
4201 [Andy Polyakov <appro@fy.chalmers.se>]
4203 *) Accept any -xxx and +xxx compiler options in Configure.
4206 *) Update HPUX configuration.
4209 *) Add missing sk_<type>_unshift() function to safestack.h
4210 [Ralf S. Engelschall]
4212 *) New function SSL_CTX_use_certificate_chain_file that sets the
4213 "extra_cert"s in addition to the certificate. (This makes sense
4214 only for "PEM" format files, as chains as a whole are not
4218 *) Support verify_depth from the SSL API.
4219 x509_vfy.c had what can be considered an off-by-one-error:
4220 Its depth (which was not part of the external interface)
4221 was actually counting the number of certificates in a chain;
4222 now it really counts the depth.
4225 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
4226 instead of X509err, which often resulted in confusing error
4227 messages since the error codes are not globally unique
4228 (e.g. an alleged error in ssl3_accept when a certificate
4229 didn't match the private key).
4231 *) New function SSL_CTX_set_session_id_context that allows to set a default
4232 value (so that you don't need SSL_set_session_id_context for each
4233 connection using the SSL_CTX).
4236 *) OAEP decoding bug fix.
4239 *) Support INSTALL_PREFIX for package builders, as proposed by
4243 *) New Configure options "threads" and "no-threads". For systems
4244 where the proper compiler options are known (currently Solaris
4245 and Linux), "threads" is the default.
4248 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
4251 *) Install various scripts to $(OPENSSLDIR)/misc, not to
4252 $(INSTALLTOP)/bin -- they shouldn't clutter directories
4253 such as /usr/local/bin.
4256 *) "make linux-shared" to build shared libraries.
4257 [Niels Poppe <niels@netbox.org>]
4259 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
4262 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
4263 extension adding in x509 utility.
4266 *) Remove NOPROTO sections and error code comments.
4269 *) Partial rewrite of the DEF file generator to now parse the ANSI
4273 *) New Configure options --prefix=DIR and --openssldir=DIR.
4276 *) Complete rewrite of the error code script(s). It is all now handled
4277 by one script at the top level which handles error code gathering,
4278 header rewriting and C source file generation. It should be much better
4279 than the old method: it now uses a modified version of Ulf's parser to
4280 read the ANSI prototypes in all header files (thus the old K&R definitions
4281 aren't needed for error creation any more) and do a better job of
4282 translating function codes into names. The old 'ASN1 error code imbedded
4283 in a comment' is no longer necessary and it doesn't use .err files which
4284 have now been deleted. Also the error code call doesn't have to appear all
4285 on one line (which resulted in some large lines...).
4288 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
4291 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
4292 0 (which usually indicates a closed connection), but continue reading.
4295 *) Fix some race conditions.
4298 *) Add support for CRL distribution points extension. Add Certificate
4299 Policies and CRL distribution points documentation.
4302 *) Move the autogenerated header file parts to crypto/opensslconf.h.
4305 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
4306 8 of keying material. Merlin has also confirmed interop with this fix
4307 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
4308 [Merlin Hughes <merlin@baltimore.ie>]
4310 *) Fix lots of warnings.
4311 [Richard Levitte <levitte@stacken.kth.se>]
4313 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
4314 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
4315 [Richard Levitte <levitte@stacken.kth.se>]
4317 *) Fix problems with sizeof(long) == 8.
4318 [Andy Polyakov <appro@fy.chalmers.se>]
4320 *) Change functions to ANSI C.
4323 *) Fix typos in error codes.
4324 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
4326 *) Remove defunct assembler files from Configure.
4329 *) SPARC v8 assembler BIGNUM implementation.
4330 [Andy Polyakov <appro@fy.chalmers.se>]
4332 *) Support for Certificate Policies extension: both print and set.
4333 Various additions to support the r2i method this uses.
4336 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
4337 return a const string when you are expecting an allocated buffer.
4340 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
4341 types DirectoryString and DisplayText.
4344 *) Add code to allow r2i extensions to access the configuration database,
4345 add an LHASH database driver and add several ctx helper functions.
4348 *) Fix an evil bug in bn_expand2() which caused various BN functions to
4349 fail when they extended the size of a BIGNUM.
4352 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
4353 support typesafe stack.
4356 *) Fix typo in SSL_[gs]et_options().
4357 [Nils Frostberg <nils@medcom.se>]
4359 *) Delete various functions and files that belonged to the (now obsolete)
4360 old X509V3 handling code.
4363 *) New Configure option "rsaref".
4366 *) Don't auto-generate pem.h.
4369 *) Introduce type-safe ASN.1 SETs.
4372 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
4373 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
4375 *) Introduce type-safe STACKs. This will almost certainly break lots of code
4376 that links with OpenSSL (well at least cause lots of warnings), but fear
4377 not: the conversion is trivial, and it eliminates loads of evil casts. A
4378 few STACKed things have been converted already. Feel free to convert more.
4379 In the fullness of time, I'll do away with the STACK type altogether.
4382 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
4383 specified in <certfile> by updating the entry in the index.txt file.
4384 This way one no longer has to edit the index.txt file manually for
4385 revoking a certificate. The -revoke option does the gory details now.
4386 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
4388 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
4389 `-text' option at all and this way the `-noout -text' combination was
4390 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
4391 [Ralf S. Engelschall]
4393 *) Make sure a corresponding plain text error message exists for the
4394 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
4395 verify callback function determined that a certificate was revoked.
4396 [Ralf S. Engelschall]
4398 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
4399 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
4400 all available cipers including rc5, which was forgotten until now.
4401 In order to let the testing shell script know which algorithms
4402 are available, a new (up to now undocumented) command
4403 "openssl list-cipher-commands" is used.
4406 *) Bugfix: s_client occasionally would sleep in select() when
4407 it should have checked SSL_pending() first.
4410 *) New functions DSA_do_sign and DSA_do_verify to provide access to
4411 the raw DSA values prior to ASN.1 encoding.
4414 *) Tweaks to Configure
4415 [Niels Poppe <niels@netbox.org>]
4417 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
4421 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
4424 *) New config option to avoid instructions that are illegal on the 80386.
4425 The default code is faster, but requires at least a 486.
4428 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
4429 SSL2_SERVER_VERSION (not used at all) macros, which are now the
4430 same as SSL2_VERSION anyway.
4433 *) New "-showcerts" option for s_client.
4436 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
4437 application. Various cleanups and fixes.
4440 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
4441 modify error routines to work internally. Add error codes and PBE init
4442 to library startup routines.
4445 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
4446 packing functions to asn1 and evp. Changed function names and error
4447 codes along the way.
4450 *) PKCS12 integration: and so it begins... First of several patches to
4451 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
4452 objects to objects.h
4455 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
4456 and display support for Thawte strong extranet extension.
4459 *) Add LinuxPPC support.
4460 [Jeff Dubrule <igor@pobox.org>]
4462 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
4463 bn_div_words in alpha.s.
4464 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
4466 *) Make sure the RSA OAEP test is skipped under -DRSAref because
4467 OAEP isn't supported when OpenSSL is built with RSAref.
4468 [Ulf Moeller <ulf@fitug.de>]
4470 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
4471 so they no longer are missing under -DNOPROTO.
4472 [Soren S. Jorvang <soren@t.dk>]
4475 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
4477 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
4478 doesn't work when the session is reused. Coming soon!
4481 *) Fix a security hole, that allows sessions to be reused in the wrong
4482 context thus bypassing client cert protection! All software that uses
4483 client certs and session caches in multiple contexts NEEDS PATCHING to
4484 allow session reuse! A fuller solution is in the works.
4485 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
4487 *) Some more source tree cleanups (removed obsolete files
4488 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
4489 permission on "config" script to be executable) and a fix for the INSTALL
4491 [Ulf Moeller <ulf@fitug.de>]
4493 *) Remove some legacy and erroneous uses of malloc, free instead of
4495 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
4497 *) Make rsa_oaep_test return non-zero on error.
4498 [Ulf Moeller <ulf@fitug.de>]
4500 *) Add support for native Solaris shared libraries. Configure
4501 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
4502 if someone would make that last step automatic.
4503 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
4505 *) ctx_size was not built with the right compiler during "make links". Fixed.
4508 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
4509 except NULL ciphers". This means the default cipher list will no longer
4510 enable NULL ciphers. They need to be specifically enabled e.g. with
4511 the string "DEFAULT:eNULL".
4514 *) Fix to RSA private encryption routines: if p < q then it would
4515 occasionally produce an invalid result. This will only happen with
4516 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
4519 *) Be less restrictive and allow also `perl util/perlpath.pl
4520 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
4521 because this way one can also use an interpreter named `perl5' (which is
4522 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
4523 installed as `perl').
4524 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4526 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
4527 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4529 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
4530 advapi32.lib to Win32 build and change the pem test comparision
4531 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
4532 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
4533 and crypto/des/ede_cbcm_enc.c.
4536 *) DES quad checksum was broken on big-endian architectures. Fixed.
4539 *) Comment out two functions in bio.h that aren't implemented. Fix up the
4540 Win32 test batch file so it (might) work again. The Win32 test batch file
4541 is horrible: I feel ill....
4544 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
4545 in e_os.h. Audit of header files to check ANSI and non ANSI
4546 sections: 10 functions were absent from non ANSI section and not exported
4547 from Windows DLLs. Fixed up libeay.num for new functions.
4550 *) Make `openssl version' output lines consistent.
4551 [Ralf S. Engelschall]
4553 *) Fix Win32 symbol export lists for BIO functions: Added
4554 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
4555 to ms/libeay{16,32}.def.
4556 [Ralf S. Engelschall]
4558 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
4559 fine under Unix and passes some trivial tests I've now added. But the
4560 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
4561 added to make sure no one expects that this stuff really works in the
4562 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
4563 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
4565 [Ralf S. Engelschall]
4567 *) Fix the generation of two part addresses in perl.
4568 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
4570 *) Add config entry for Linux on MIPS.
4571 [John Tobey <jtobey@channel1.com>]
4573 *) Make links whenever Configure is run, unless we are on Windoze.
4576 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
4577 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
4581 *) Add a useful kludge to allow package maintainers to specify compiler and
4582 other platforms details on the command line without having to patch the
4583 Configure script everytime: One now can use ``perl Configure
4584 <id>:<details>'', i.e. platform ids are allowed to have details appended
4585 to them (seperated by colons). This is treated as there would be a static
4586 pre-configured entry in Configure's %table under key <id> with value
4587 <details> and ``perl Configure <id>'' is called. So, when you want to
4588 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
4589 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
4590 now, which overrides the FreeBSD-elf entry on-the-fly.
4591 [Ralf S. Engelschall]
4593 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
4596 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
4597 on the `perl Configure ...' command line. This way one can compile
4598 OpenSSL libraries with Position Independent Code (PIC) which is needed
4599 for linking it into DSOs.
4600 [Ralf S. Engelschall]
4602 *) Remarkably, export ciphers were totally broken and no-one had noticed!
4606 *) Cleaned up the LICENSE document: The official contact for any license
4607 questions now is the OpenSSL core team under openssl-core@openssl.org.
4608 And add a paragraph about the dual-license situation to make sure people
4609 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
4610 to the OpenSSL toolkit.
4611 [Ralf S. Engelschall]
4613 *) General source tree makefile cleanups: Made `making xxx in yyy...'
4614 display consistent in the source tree and replaced `/bin/rm' by `rm'.
4615 Additonally cleaned up the `make links' target: Remove unnecessary
4616 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
4617 to speed processing and no longer clutter the display with confusing
4618 stuff. Instead only the actually done links are displayed.
4619 [Ralf S. Engelschall]
4621 *) Permit null encryption ciphersuites, used for authentication only. It used
4622 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
4623 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
4627 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
4628 signed attributes when verifying signatures (this would break them),
4629 the detached data encoding was wrong and public keys obtained using
4630 X509_get_pubkey() weren't freed.
4633 *) Add text documentation for the BUFFER functions. Also added a work around
4634 to a Win95 console bug. This was triggered by the password read stuff: the
4635 last character typed gets carried over to the next fread(). If you were
4636 generating a new cert request using 'req' for example then the last
4637 character of the passphrase would be CR which would then enter the first
4641 *) Added the new `Includes OpenSSL Cryptography Software' button as
4642 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
4643 button and can be used by applications based on OpenSSL to show the
4644 relationship to the OpenSSL project.
4645 [Ralf S. Engelschall]
4647 *) Remove confusing variables in function signatures in files
4648 ssl/ssl_lib.c and ssl/ssl.h.
4649 [Lennart Bong <lob@kulthea.stacken.kth.se>]
4651 *) Don't install bss_file.c under PREFIX/include/
4652 [Lennart Bong <lob@kulthea.stacken.kth.se>]
4654 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
4655 functions that return function pointers and has support for NT specific
4656 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
4657 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
4658 unsigned to signed types: this was killing the Win32 compile.
4661 *) Add new certificate file to stack functions,
4662 SSL_add_dir_cert_subjects_to_stack() and
4663 SSL_add_file_cert_subjects_to_stack(). These largely supplant
4664 SSL_load_client_CA_file(), and can be used to add multiple certs easily
4665 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
4666 This means that Apache-SSL and similar packages don't have to mess around
4667 to add as many CAs as they want to the preferred list.
4670 *) Experiment with doxygen documentation. Currently only partially applied to
4672 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
4673 openssl.doxy as the configuration file.
4676 *) Get rid of remaining C++-style comments which strict C compilers hate.
4677 [Ralf S. Engelschall, pointed out by Carlos Amengual]
4679 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
4680 compiled in by default: it has problems with large keys.
4683 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
4684 DH private keys and/or callback functions which directly correspond to
4685 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
4686 is needed for applications which have to configure certificates on a
4687 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
4689 For the RSA certificate situation is makes no difference, but
4690 for the DSA certificate situation this fixes the "no shared cipher"
4691 problem where the OpenSSL cipher selection procedure failed because the
4692 temporary keys were not overtaken from the context and the API provided
4693 no way to reconfigure them.
4694 The new functions now let applications reconfigure the stuff and they
4695 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
4696 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
4697 non-public-API function ssl_cert_instantiate() is used as a helper
4698 function and also to reduce code redundancy inside ssl_rsa.c.
4699 [Ralf S. Engelschall]
4701 *) Move s_server -dcert and -dkey options out of the undocumented feature
4702 area because they are useful for the DSA situation and should be
4703 recognized by the users.
4704 [Ralf S. Engelschall]
4706 *) Fix the cipher decision scheme for export ciphers: the export bits are
4707 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
4708 SSL_EXP_MASK. So, the original variable has to be used instead of the
4709 already masked variable.
4710 [Richard Levitte <levitte@stacken.kth.se>]
4712 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
4713 [Richard Levitte <levitte@stacken.kth.se>]
4715 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
4716 from `int' to `unsigned int' because it's a length and initialized by
4717 EVP_DigestFinal() which expects an `unsigned int *'.
4718 [Richard Levitte <levitte@stacken.kth.se>]
4720 *) Don't hard-code path to Perl interpreter on shebang line of Configure
4721 script. Instead use the usual Shell->Perl transition trick.
4722 [Ralf S. Engelschall]
4724 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
4725 (in addition to RSA certificates) to match the behaviour of `openssl dsa
4726 -noout -modulus' as it's already the case for `openssl rsa -noout
4727 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
4728 currently the public key is printed (a decision which was already done by
4729 `openssl dsa -modulus' in the past) which serves a similar purpose.
4730 Additionally the NO_RSA no longer completely removes the whole -modulus
4731 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
4733 [Ralf S. Engelschall]
4735 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
4736 BIO. See the source (crypto/evp/bio_ok.c) for more info.
4737 [Arne Ansper <arne@ats.cyber.ee>]
4739 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
4740 to be added. Now both 'req' and 'ca' can use new objects defined in the
4744 *) Add cool BIO that does syslog (or event log on NT).
4745 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
4747 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
4748 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
4749 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
4750 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
4753 *) Add preliminary config info for new extension code.
4756 *) Make RSA_NO_PADDING really use no padding.
4757 [Ulf Moeller <ulf@fitug.de>]
4759 *) Generate errors when private/public key check is done.
4762 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
4763 for some CRL extensions and new objects added.
4766 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
4767 key usage extension and fuller support for authority key id.
4770 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
4771 padding method for RSA, which is recommended for new applications in PKCS
4772 #1 v2.0 (RFC 2437, October 1998).
4773 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
4774 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
4775 against Bleichbacher's attack on RSA.
4776 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
4779 *) Updates to the new SSL compression code
4780 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4782 *) Fix so that the version number in the master secret, when passed
4783 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
4784 (because the server will not accept higher), that the version number
4785 is 0x03,0x01, not 0x03,0x00
4786 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4788 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
4789 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
4790 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
4793 *) Support for RAW extensions where an arbitrary extension can be
4794 created by including its DER encoding. See apps/openssl.cnf for
4798 *) Make sure latest Perl versions don't interpret some generated C array
4799 code as Perl array code in the crypto/err/err_genc.pl script.
4800 [Lars Weber <3weber@informatik.uni-hamburg.de>]
4802 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
4803 not many people have the assembler. Various Win32 compilation fixes and
4804 update to the INSTALL.W32 file with (hopefully) more accurate Win32
4808 *) Modify configure script 'Configure' to automatically create crypto/date.h
4809 file under Win32 and also build pem.h from pem.org. New script
4810 util/mkfiles.pl to create the MINFO file on environments that can't do a
4811 'make files': perl util/mkfiles.pl >MINFO should work.
4814 *) Major rework of DES function declarations, in the pursuit of correctness
4815 and purity. As a result, many evil casts evaporated, and some weirdness,
4816 too. You may find this causes warnings in your code. Zapping your evil
4817 casts will probably fix them. Mostly.
4820 *) Fix for a typo in asn1.h. Bug fix to object creation script
4821 obj_dat.pl. It considered a zero in an object definition to mean
4822 "end of object": none of the objects in objects.h have any zeros
4823 so it wasn't spotted.
4824 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
4826 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
4827 Masking (CBCM). In the absence of test vectors, the best I have been able
4828 to do is check that the decrypt undoes the encrypt, so far. Send me test
4829 vectors if you have them.
4832 *) Correct calculation of key length for export ciphers (too much space was
4833 allocated for null ciphers). This has not been tested!
4836 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
4837 message is now correct (it understands "crypto" and "ssl" on its
4838 command line). There is also now an "update" option. This will update
4839 the util/ssleay.num and util/libeay.num files with any new functions.
4841 perl util/mkdef.pl crypto ssl update
4842 it will update them.
4845 *) Overhauled the Perl interface (perl/*):
4846 - ported BN stuff to OpenSSL's different BN library
4847 - made the perl/ source tree CVS-aware
4848 - renamed the package from SSLeay to OpenSSL (the files still contain
4849 their history because I've copied them in the repository)
4850 - removed obsolete files (the test scripts will be replaced
4851 by better Test::Harness variants in the future)
4852 [Ralf S. Engelschall]
4854 *) First cut for a very conservative source tree cleanup:
4855 1. merge various obsolete readme texts into doc/ssleay.txt
4856 where we collect the old documents and readme texts.
4857 2. remove the first part of files where I'm already sure that we no
4858 longer need them because of three reasons: either they are just temporary
4859 files which were left by Eric or they are preserved original files where
4860 I've verified that the diff is also available in the CVS via "cvs diff
4861 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
4862 the crypto/md/ stuff).
4863 [Ralf S. Engelschall]
4865 *) More extension code. Incomplete support for subject and issuer alt
4866 name, issuer and authority key id. Change the i2v function parameters
4867 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
4868 what that's for :-) Fix to ASN1 macro which messed up
4869 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
4872 *) Preliminary support for ENUMERATED type. This is largely copied from the
4876 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
4877 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4879 *) Make sure `make rehash' target really finds the `openssl' program.
4880 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4882 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
4883 like to hear about it if this slows down other processors.
4886 *) Add CygWin32 platform information to Configure script.
4887 [Alan Batie <batie@aahz.jf.intel.com>]
4889 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
4890 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
4892 *) New program nseq to manipulate netscape certificate sequences
4895 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
4899 *) Fixes to BN code. Previously the default was to define BN_RECURSION
4900 but the BN code had some problems that would cause failures when
4901 doing certificate verification and some other functions.
4902 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4904 *) Add ASN1 and PEM code to support netscape certificate sequences.
4907 *) Add ASN1 and PEM code to support netscape certificate sequences.
4910 *) Add several PKIX and private extended key usage OIDs.
4913 *) Modify the 'ca' program to handle the new extension code. Modify
4914 openssl.cnf for new extension format, add comments.
4917 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
4918 and add a sample to openssl.cnf so req -x509 now adds appropriate
4922 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
4923 error code, add initial support to X509_print() and x509 application.
4926 *) Takes a deep breath and start addding X509 V3 extension support code. Add
4927 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
4928 stuff is currently isolated and isn't even compiled yet.
4931 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
4932 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
4933 Removed the versions check from X509 routines when loading extensions:
4934 this allows certain broken certificates that don't set the version
4935 properly to be processed.
4938 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
4939 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
4940 can still be regenerated with "make depend".
4943 *) Spelling mistake in C version of CAST-128.
4944 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
4946 *) Changes to the error generation code. The perl script err-code.pl
4947 now reads in the old error codes and retains the old numbers, only
4948 adding new ones if necessary. It also only changes the .err files if new
4949 codes are added. The makefiles have been modified to only insert errors
4950 when needed (to avoid needlessly modifying header files). This is done
4951 by only inserting errors if the .err file is newer than the auto generated
4952 C file. To rebuild all the error codes from scratch (the old behaviour)
4953 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
4954 or delete all the .err files.
4957 *) CAST-128 was incorrectly implemented for short keys. The C version has
4958 been fixed, but is untested. The assembler versions are also fixed, but
4959 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
4960 to regenerate it if needed.
4961 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
4962 Hagino <itojun@kame.net>]
4964 *) File was opened incorrectly in randfile.c.
4965 [Ulf Möller <ulf@fitug.de>]
4967 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
4968 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
4969 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
4970 al: it's just almost always a UTCTime. Note this patch adds new error
4971 codes so do a "make errors" if there are problems.
4974 *) Correct Linux 1 recognition in config.
4975 [Ulf Möller <ulf@fitug.de>]
4977 *) Remove pointless MD5 hash when using DSA keys in ca.
4978 [Anonymous <nobody@replay.com>]
4980 *) Generate an error if given an empty string as a cert directory. Also
4981 generate an error if handed NULL (previously returned 0 to indicate an
4982 error, but didn't set one).
4983 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
4985 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
4988 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
4989 parameters. This was causing a warning which killed off the Win32 compile.
4992 *) Remove C++ style comments from crypto/bn/bn_local.h.
4993 [Neil Costigan <neil.costigan@celocom.com>]
4995 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
4996 based on a text string, looking up short and long names and finally
4997 "dot" format. The "dot" format stuff didn't work. Added new function
4998 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
4999 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
5000 OID is not part of the table.
5003 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
5004 X509_LOOKUP_by_alias().
5007 *) Sort openssl functions by name.
5010 *) Get the gendsa program working (hopefully) and add it to app list. Remove
5011 encryption from sample DSA keys (in case anyone is interested the password
5015 *) Make _all_ *_free functions accept a NULL pointer.
5016 [Frans Heymans <fheymans@isaserver.be>]
5018 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
5020 [Anonymous <nobody@replay.com>]
5022 *) s_server should send the CAfile as acceptable CAs, not its own cert.
5023 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
5025 *) Don't blow it for numeric -newkey arguments to apps/req.
5026 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
5028 *) Temp key "for export" tests were wrong in s3_srvr.c.
5029 [Anonymous <nobody@replay.com>]
5031 *) Add prototype for temp key callback functions
5032 SSL_CTX_set_tmp_{rsa,dh}_callback().
5035 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
5036 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
5039 *) X509_name_add_entry() freed the wrong thing after an error.
5040 [Arne Ansper <arne@ats.cyber.ee>]
5042 *) rsa_eay.c would attempt to free a NULL context.
5043 [Arne Ansper <arne@ats.cyber.ee>]
5045 *) BIO_s_socket() had a broken should_retry() on Windoze.
5046 [Arne Ansper <arne@ats.cyber.ee>]
5048 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
5049 [Arne Ansper <arne@ats.cyber.ee>]
5051 *) Make sure the already existing X509_STORE->depth variable is initialized
5052 in X509_STORE_new(), but document the fact that this variable is still
5053 unused in the certificate verification process.
5054 [Ralf S. Engelschall]
5056 *) Fix the various library and apps files to free up pkeys obtained from
5057 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
5060 *) Fix reference counting in X509_PUBKEY_get(). This makes
5061 demos/maurice/example2.c work, amongst others, probably.
5062 [Steve Henson and Ben Laurie]
5064 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
5065 `openssl' and second, the shortcut symlinks for the `openssl <command>'
5066 are no longer created. This way we have a single and consistent command
5067 line interface `openssl <command>', similar to `cvs <command>'.
5068 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
5070 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
5071 BIT STRING wrapper always have zero unused bits.
5074 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
5077 *) Make the top-level INSTALL documentation easier to understand.
5080 *) Makefiles updated to exit if an error occurs in a sub-directory
5081 make (including if user presses ^C) [Paul Sutton]
5083 *) Make Montgomery context stuff explicit in RSA data structure.
5086 *) Fix build order of pem and err to allow for generated pem.h.
5089 *) Fix renumbering bug in X509_NAME_delete_entry().
5092 *) Enhanced the err-ins.pl script so it makes the error library number
5093 global and can add a library name. This is needed for external ASN1 and
5094 other error libraries.
5097 *) Fixed sk_insert which never worked properly.
5100 *) Fix ASN1 macros so they can handle indefinite length construted
5101 EXPLICIT tags. Some non standard certificates use these: they can now
5105 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
5106 into a single doc/ssleay.txt bundle. This way the information is still
5107 preserved but no longer messes up this directory. Now it's new room for
5108 the new set of documenation files.
5109 [Ralf S. Engelschall]
5111 *) SETs were incorrectly DER encoded. This was a major pain, because they
5112 shared code with SEQUENCEs, which aren't coded the same. This means that
5113 almost everything to do with SETs or SEQUENCEs has either changed name or
5114 number of arguments.
5115 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
5117 *) Fix test data to work with the above.
5120 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
5121 was already fixed by Eric for 0.9.1 it seems.
5122 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
5124 *) Autodetect FreeBSD3.
5127 *) Fix various bugs in Configure. This affects the following platforms:
5131 unixware-2.0-pentium
5135 *) Eliminate generated files from CVS. Reorder tests to regenerate files
5136 before they are needed.
5139 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
5143 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
5145 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
5146 changed SSLeay to OpenSSL in version strings.
5147 [Ralf S. Engelschall]
5149 *) Some fixups to the top-level documents.
5152 *) Fixed the nasty bug where rsaref.h was not found under compile-time
5153 because the symlink to include/ was missing.
5154 [Ralf S. Engelschall]
5156 *) Incorporated the popular no-RSA/DSA-only patches
5157 which allow to compile a RSA-free SSLeay.
5158 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
5160 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
5161 when "ssleay" is still not found.
5162 [Ralf S. Engelschall]
5164 *) Added more platforms to Configure: Cray T3E, HPUX 11,
5165 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
5167 *) Updated the README file.
5168 [Ralf S. Engelschall]
5170 *) Added various .cvsignore files in the CVS repository subdirs
5171 to make a "cvs update" really silent.
5172 [Ralf S. Engelschall]
5174 *) Recompiled the error-definition header files and added
5175 missing symbols to the Win32 linker tables.
5176 [Ralf S. Engelschall]
5178 *) Cleaned up the top-level documents;
5179 o new files: CHANGES and LICENSE
5180 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
5181 o merged COPYRIGHT into LICENSE
5182 o removed obsolete TODO file
5183 o renamed MICROSOFT to INSTALL.W32
5184 [Ralf S. Engelschall]
5186 *) Removed dummy files from the 0.9.1b source tree:
5187 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
5188 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

5191 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
5192 [Ralf S. Engelschall]
5194 *) Added various platform portability fixes.
5197 *) The Genesis of the OpenSSL rpject:
5198 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
5199 Young and Tim J. Hudson created while they were working for C2Net until
5201 [The OpenSSL Project]
5204 Changes between 0.9.0b and 0.9.1b [not released]
5206 *) Updated a few CA certificates under certs/
5209 *) Changed some BIGNUM api stuff.
5212 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
5213 DGUX x86, Linux Alpha, etc.
5216 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
5217 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
5221 *) Add -strparse option to asn1pars program which parses nested
5223 [Dr Stephen Henson <shenson@bigfoot.com>]
5225 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
5228 *) DSA fix for "ca" program.
5231 *) Added "-genkey" option to "dsaparam" program.
5234 *) Added RIPE MD160 (rmd160) message digest.
5237 *) Added -a (all) option to "ssleay version" command.
5240 *) Added PLATFORM define which is the id given to Configure.
5243 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
5246 *) Extended the ASN.1 parser routines.
5249 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
5252 *) Added a BN_CTX to the BN library.
5255 *) Fixed the weak key values in DES library
5258 *) Changed API in EVP library for cipher aliases.
5261 *) Added support for RC2/64bit cipher.
5264 *) Converted the lhash library to the crypto/mem.c functions.
5267 *) Added more recognized ASN.1 object ids.
5270 *) Added more RSA padding checks for SSL/TLS.
5273 *) Added BIO proxy/filter functionality.
5276 *) Added extra_certs to SSL_CTX which can be used
5277 send extra CA certificates to the client in the CA cert chain sending
5278 process. It can be configured with SSL_CTX_add_extra_chain_cert().
5281 *) Now Fortezza is denied in the authentication phase because
5282 this is key exchange mechanism is not supported by SSLeay at all.
5285 *) Additional PKCS1 checks.
5288 *) Support the string "TLSv1" for all TLS v1 ciphers.
5291 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
5292 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
5295 *) Fixed a few memory leaks.
5298 *) Fixed various code and comment typos.
5301 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
5302 bytes sent in the client random.
