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 +) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c.
16 [Ben Laurie and Theo de Raadt]
18 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
19 <Dominikus.Scherkl@biodata.com>. (The previous implementation
20 worked incorrectly for those cases where range = 10..._2 and
21 3*range is two bits longer than range.)
24 *) Only add signing time to PKCS7 structures if it is not already
28 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
29 OBJ_ld_ce should be OBJ_id_ce.
30 Also some ip-pda OIDs in crypto/objects/objects.txt were
31 incorrect (cf. RFC 3039).
32 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
34 +) Add option to output public keys in req command.
35 [Massimiliano Pala madwolf@openca.org]
37 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
38 returns early because it has nothing to do.
39 [Andy Schneider <andy.schneider@bjss.co.uk>]
41 *) [In 0.9.6c-engine and 0.9.7 release:]
42 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
43 [Andy Schneider <andy.schneider@bjss.co.uk>]
45 -) [In 0.9.6c-engine release:]
46 Add support for Cryptographic Appliance's keyserver technology.
47 (Use engine 'keyclient')
48 [Cryptographic Appliances and Geoff Thorpe]
50 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
51 is called via tools/c89.sh because arguments have to be
52 rearranged (all '-L' options must appear before the first object
54 [Richard Shapiro <rshapiro@abinitio.com>]
56 +) Use wNAFs in EC_POINTs_mul() for improved efficiency
57 (up to about 10% better than before for P-192 and P-224).
60 -) [In 0.9.6c-engine release:]
61 Add support for Broadcom crypto accelerator cards, backported
63 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
65 -) [In 0.9.6c-engine release:]
66 Add support for SureWare crypto accelerator cards from
67 Baltimore Technologies. (Use engine 'sureware')
68 [Baltimore Technologies and Mark Cox]
70 -) [In 0.9.6c-engine release:]
71 Add support for crypto accelerator cards from Accelerated
72 Encryption Processing, www.aep.ie. (Use engine 'aep')
73 [AEP Inc. and Mark Cox]
75 *) Add a configuration entry for gcc on UnixWare.
76 [Gary Benson <gbenson@redhat.com>]
78 +) New functions/macros
80 SSL_CTX_set_msg_callback(ctx, cb)
81 SSL_CTX_set_msg_callback_arg(ctx, arg)
82 SSL_set_msg_callback(ssl, cb)
83 SSL_set_msg_callback_arg(ssl, arg)
85 to request calling a callback function
87 void cb(int write_p, int version, int content_type,
88 const void *buf, size_t len, SSL *ssl, void *arg)
90 whenever a protocol message has been completely received
91 (write_p == 0) or sent (write_p == 1). Here 'version' is the
92 protocol version according to which the SSL library interprets
93 the current protocol message (SSL2_VERSION, SSL3_VERSION, or
94 TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or
95 the content type as defined in the SSL 3.0/TLS 1.0 protocol
96 specification (change_cipher_spec(20), alert(21), handshake(22)).
97 'buf' and 'len' point to the actual message, 'ssl' to the
98 SSL object, and 'arg' is the application-defined value set by
99 SSL[_CTX]_set_msg_callback_arg().
101 'openssl s_client' and 'openssl s_server' have new '-msg' options
102 to enable a callback that displays all protocol messages.
105 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
106 messages are stored in a single piece (fixed-length part and
107 variable-length part combined) and fix various bugs found on the way.
110 +) Change the shared library support so shared libraries are built as
111 soon as the corresponding static library is finished, and thereby get
112 openssl and the test programs linked against the shared library.
113 This still only happens when the keyword "shard" has been given to
114 the configuration scripts.
116 NOTE: shared library support is still an experimental thing, and
117 backward binary compatibility is still not guaranteed.
118 ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte]
120 +) Add support for Subject Information Access extension.
121 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
123 +) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero
124 additional bytes when new memory had to be allocated, not just
125 when reusing an existing buffer.
128 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
129 instead. BIO_gethostbyname() does not know what timeouts are
130 appropriate, so entries would stay in cache even when they have
132 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
134 +) New command line and configuration option 'utf8' for the req command.
135 This allows field values to be specified as UTF8 strings.
138 +) Add -multi and -mr options to "openssl speed" - giving multiple parallel
139 runs for the former and machine-readable output for the latter.
142 +) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion
143 of the e-mail address in the DN (i.e., it will go into a certificate
144 extension only). The new configuration file option 'email_in_dn = no'
146 [Massimiliano Pala madwolf@openca.org]
148 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
149 faced with a pathologically small ClientHello fragment that does
150 not contain client_version: Instead of aborting with an error,
151 simply choose the highest available protocol version (i.e.,
152 TLS 1.0 unless it is disabled). In practice, ClientHello
153 messages are never sent like this, but this change gives us
154 strictly correct behaviour at least for TLS.
157 +) Change all functions with names starting with des_ to be starting
158 with DES_ instead. This because there are increasing clashes with
159 libdes and other des libraries that are currently used by other
160 projects. The old libdes interface is provided, as well as crypt(),
161 if openssl/des_old.h is included. Note that crypt() is no longer
162 declared in openssl/des.h.
164 NOTE: This is a major break of an old API into a new one. Software
165 authors are encouraged to switch to the DES_ style functions. Some
166 time in the future, des_old.h and the libdes compatibility functions
167 will be completely removed.
170 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
171 never resets s->method to s->ctx->method when called from within
172 one of the SSL handshake functions.
173 [Bodo Moeller; problem pointed out by Niko Baric]
175 +) Test for certificates which contain unsupported critical extensions.
176 If such a certificate is found during a verify operation it is
177 rejected by default: this behaviour can be overridden by either
178 handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
179 by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
180 X509_supported_extension() has also been added which returns 1 if a
181 particular extension is supported.
184 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
185 (sent using the client's version number) if client_version is
186 smaller than the protocol version in use. Also change
187 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
188 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
189 the client will at least see that alert.
192 +) Modify the behaviour of EVP cipher functions in similar way to digests
193 to retain compatibility with existing code.
196 +) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain
197 compatibility with existing code. In particular the 'ctx' parameter does
198 not have to be to be initialized before the call to EVP_DigestInit() and
199 it is tidied up after a call to EVP_DigestFinal(). New function
200 EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
201 EVP_MD_CTX_copy() changed to not require the destination to be
202 initialized valid and new function EVP_MD_CTX_copy_ex() added which
203 requires the destination to be valid.
205 Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
206 EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
209 +) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
210 so that complete 'Handshake' protocol structures are kept in memory
211 instead of overwriting 'msg_type' and 'length' with 'body' data.
214 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
218 +) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
219 [Massimo Santin via Richard Levitte]
221 +) Major restructuring to the underlying ENGINE code. This includes
222 reduction of linker bloat, separation of pure "ENGINE" manipulation
223 (initialisation, etc) from functionality dealing with implementations
224 of specific crypto iterfaces. This change also introduces integrated
225 support for symmetric ciphers and digest implementations - so ENGINEs
226 can now accelerate these by providing EVP_CIPHER and EVP_MD
227 implementations of their own. This is detailed in crypto/engine/README
228 as it couldn't be adequately described here. However, there are a few
229 API changes worth noting - some RSA, DSA, DH, and RAND functions that
230 were changed in the original introduction of ENGINE code have now
231 reverted back - the hooking from this code to ENGINE is now a good
232 deal more passive and at run-time, operations deal directly with
233 RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
234 dereferencing through an ENGINE pointer any more. Also, the ENGINE
235 functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
236 they were not being used by the framework as there is no concept of a
237 BIGNUM_METHOD and they could not be generalised to the new
238 'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
239 ENGINE_cpy() has been removed as it cannot be consistently defined in
243 +) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
246 +) Change mkdef.pl to sort symbols that get the same entry number,
247 and make sure the automatically generated functions ERR_load_*
248 become part of libeay.num as well.
251 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
252 client receives HelloRequest while in a handshake.
253 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
255 +) New function SSL_renegotiate_pending(). This returns true once
256 renegotiation has been requested (either SSL_renegotiate() call
257 or HelloRequest/ClientHello receveived from the peer) and becomes
258 false once a handshake has been completed.
259 (For servers, SSL_renegotiate() followed by SSL_do_handshake()
260 sends a HelloRequest, but does not ensure that a handshake takes
261 place. SSL_renegotiate_pending() is useful for checking if the
262 client has followed the request.)
265 +) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
266 By default, clients may request session resumption even during
267 renegotiation (if session ID contexts permit); with this option,
268 session resumption is possible only in the first handshake.
271 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
272 should end in 'break', not 'goto end' which circuments various
273 cleanups done in state SSL_ST_OK. But session related stuff
274 must be disabled for SSL_ST_OK in the case that we just sent a
277 Also avoid some overhead by not calling ssl_init_wbio_buffer()
278 before just sending a HelloRequest.
279 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
281 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
282 reveal whether illegal block cipher padding was found or a MAC
283 verification error occured. (Neither SSLerr() codes nor alerts
284 are directly visible to potential attackers, but the information
285 may leak via logfiles.)
287 Similar changes are not required for the SSL 2.0 implementation
288 because the number of padding bytes is sent in clear for SSL 2.0,
289 and the extra bytes are just ignored. However ssl/s2_pkt.c
290 failed to verify that the purported number of padding bytes is in
294 +) Add some demos for certificate and certificate request creation.
297 +) Make maximum certificate chain size accepted from the peer application
298 settable (SSL*_get/set_max_cert_list()), as proposed by
299 "Douglas E. Engert" <deengert@anl.gov>.
302 +) Add support for shared libraries for Unixware-7
303 (Boyd Lynn Gerber <gerberb@zenez.com>).
306 *) Add OpenUNIX-8 support including shared libraries
307 (Boyd Lynn Gerber <gerberb@zenez.com>).
310 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
311 'wristwatch attack' using huge encoding parameters (cf.
312 James H. Manger's CRYPTO 2001 paper). Note that the
313 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
314 encoding parameters and hence was not vulnerable.
317 +) Add a "destroy" handler to ENGINEs that allows structural cleanup to
318 be done prior to destruction. Use this to unload error strings from
319 ENGINEs that load their own error strings. NB: This adds two new API
320 functions to "get" and "set" this destroy handler in an ENGINE.
323 +) Alter all existing ENGINE implementations (except "openssl" and
324 "openbsd") to dynamically instantiate their own error strings. This
325 makes them more flexible to be built both as statically-linked ENGINEs
326 and self-contained shared-libraries loadable via the "dynamic" ENGINE.
327 Also, add stub code to each that makes building them as self-contained
328 shared-libraries easier (see README.ENGINE).
331 +) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
332 implementations into applications that are completely implemented in
333 self-contained shared-libraries. The "dynamic" ENGINE exposes control
334 commands that can be used to configure what shared-library to load and
335 to control aspects of the way it is handled. Also, made an update to
336 the README.ENGINE file that brings its information up-to-date and
337 provides some information and instructions on the "dynamic" ENGINE
338 (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
342 [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
344 +) Make it possible to unload ranges of ERR strings with a new
345 "ERR_unload_strings" function.
348 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
349 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
350 followed by modular reduction.
351 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
353 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
354 equivalent based on BN_pseudo_rand() instead of BN_rand().
357 +) Add a copy() function to EVP_MD.
360 +) Make EVP_MD routines take a context pointer instead of just the
361 md_data void pointer.
364 +) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
365 that the digest can only process a single chunk of data
366 (typically because it is provided by a piece of
367 hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
368 is only going to provide a single chunk of data, and hence the
369 framework needn't accumulate the data for oneshot drivers.
372 +) As with "ERR", make it possible to replace the underlying "ex_data"
373 functions. This change also alters the storage and management of global
374 ex_data state - it's now all inside ex_data.c and all "class" code (eg.
375 RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
376 index counters. The API functions that use this state have been changed
377 to take a "class_index" rather than pointers to the class's local STACK
378 and counter, and there is now an API function to dynamically create new
379 classes. This centralisation allows us to (a) plug a lot of the
380 thread-safety problems that existed, and (b) makes it possible to clean
381 up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
382 such data would previously have always leaked in application code and
383 workarounds were in place to make the memory debugging turn a blind eye
384 to it. Application code that doesn't use this new function will still
385 leak as before, but their memory debugging output will announce it now
386 rather than letting it slide.
388 Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
389 induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
390 has a return value to indicate success or failure.
393 +) Make it possible to replace the underlying "ERR" functions such that the
394 global state (2 LHASH tables and 2 locks) is only used by the "default"
395 implementation. This change also adds two functions to "get" and "set"
396 the implementation prior to it being automatically set the first time
397 any other ERR function takes place. Ie. an application can call "get",
398 pass the return value to a module it has just loaded, and that module
399 can call its own "set" function using that value. This means the
400 module's "ERR" operations will use (and modify) the error state in the
401 application and not in its own statically linked copy of OpenSSL code.
404 +) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
405 reference counts. This performs normal REF_PRINT/REF_CHECK macros on
406 the operation, and provides a more encapsulated way for external code
407 (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
408 to use these functions rather than manually incrementing the counts.
410 Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
413 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
414 This function was broken, as the check for a new client hello message
415 to handle SGC did not allow these large messages.
416 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
419 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
422 +) Add EVP test program.
425 +) Add symmetric cipher support to ENGINE. Expect the API to change!
428 +) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
429 X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
430 X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
431 These allow a CRL to be built without having to access X509_CRL fields
432 directly. Modify 'ca' application to use new functions.
435 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
436 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
439 *) Rework the configuration and shared library support for Tru64 Unix.
440 The configuration part makes use of modern compiler features and
441 still retains old compiler behavior for those that run older versions
442 of the OS. The shared library support part includes a variant that
443 uses the RPATH feature, and is available through the special
444 configuration target "alpha-cc-rpath", which will never be selected
446 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
448 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
449 with the same message size as in ssl3_get_certificate_request().
450 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
451 messages might inadvertently be reject as too long.
452 [Petr Lampa <lampa@fee.vutbr.cz>]
454 +) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
455 bug workarounds. Rollback attack detection is a security feature.
456 The problem will only arise on OpenSSL servers when TLSv1 is not
457 available (sslv3_server_method() or SSL_OP_NO_TLSv1).
458 Software authors not wanting to support TLSv1 will have special reasons
459 for their choice and can explicitly enable this option.
460 [Bodo Moeller, Lutz Jaenicke]
462 +) Rationalise EVP so it can be extended: don't include a union of
463 cipher/digest structures, add init/cleanup functions. This also reduces
464 the number of header dependencies.
467 +) Make DES key schedule conform to the usual scheme, as well as
468 correcting its structure. This means that calls to DES functions
469 now have to pass a pointer to a des_key_schedule instead of a
470 plain des_key_schedule (which was actually always a pointer
474 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
477 *) Modified SSL library such that the verify_callback that has been set
478 specificly for an SSL object with SSL_set_verify() is actually being
479 used. Before the change, a verify_callback set with this function was
480 ignored and the verify_callback() set in the SSL_CTX at the time of
481 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
482 to allow the necessary settings.
485 +) Initial reduction of linker bloat: the use of some functions, such as
486 PEM causes large amounts of unused functions to be linked in due to
487 poor organisation. For example pem_all.c contains every PEM function
488 which has a knock on effect of linking in large amounts of (unused)
489 ASN1 code. Grouping together similar functions and splitting unrelated
490 functions prevents this.
493 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
494 explicitly to NULL, as at least on Solaris 8 this seems not always to be
495 done automatically (in contradiction to the requirements of the C
496 standard). This made problems when used from OpenSSH.
499 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
500 dh->length and always used
502 BN_rand_range(priv_key, dh->p).
504 BN_rand_range() is not necessary for Diffie-Hellman, and this
505 specific range makes Diffie-Hellman unnecessarily inefficient if
506 dh->length (recommended exponent length) is much smaller than the
507 length of dh->p. We could use BN_rand_range() if the order of
508 the subgroup was stored in the DH structure, but we only have
513 BN_rand(priv_key, l, ...)
515 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
521 RSA_eay_public_encrypt
522 RSA_eay_private_decrypt
523 RSA_eay_private_encrypt (signing)
524 RSA_eay_public_decrypt (signature verification)
526 (default implementations for RSA_public_encrypt,
527 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
528 always reject numbers >= n.
531 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
532 to synchronize access to 'locking_thread'. This is necessary on
533 systems where access to 'locking_thread' (an 'unsigned long'
534 variable) is not atomic.
537 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
538 *before* setting the 'crypto_lock_rand' flag. The previous code had
539 a race condition if 0 is a valid thread ID.
540 [Travis Vitek <vitek@roguewave.com>]
542 +) Cleanup of EVP macros.
545 +) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
549 +) Add initial OCSP responder support to ocsp application. The
550 revocation information is handled using the text based index
551 use by the ca application. The responder can either handle
552 requests generated internally, supplied in files (for example
553 via a CGI script) or using an internal minimal server.
556 +) Add configuration choices to get zlib compression for TLS.
559 +) Changes to Kerberos SSL for RFC 2712 compliance:
560 1. Implemented real KerberosWrapper, instead of just using
561 KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
562 2. Implemented optional authenticator field of KerberosWrapper.
564 Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
565 and authenticator structs; see crypto/krb5/.
567 Generalized Kerberos calls to support multiple Kerberos libraries.
568 [Vern Staats <staatsvr@asc.hpc.mil>,
569 Jeffrey Altman <jaltman@columbia.edu>
572 +) Cause 'openssl speed' to use fully hard-coded DSA keys as it
573 already does with RSA. testdsa.h now has 'priv_key/pub_key'
574 values for each of the key sizes rather than having just
575 parameters (and 'speed' generating keys each time).
578 *) Add support for shared libraries under Irix.
579 [Albert Chin-A-Young <china@thewrittenword.com>]
581 *) Add configuration option to build on Linux on both big-endian and

585 *) Add the possibility to create shared libraries on HP-UX.
588 -) OpenSSL 0.9.6b released [9 July 2001]
590 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
591 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
592 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
593 PRNG state recovery was possible based on the output of
594 one PRNG request appropriately sized to gain knowledge on
595 'md' followed by enough consecutive 1-byte PRNG requests
596 to traverse all of 'state'.
598 1. When updating 'md_local' (the current thread's copy of 'md')
599 during PRNG output generation, hash all of the previous
600 'md_local' value, not just the half used for PRNG output.
602 2. Make the number of bytes from 'state' included into the hash
603 independent from the number of PRNG bytes requested.
605 The first measure alone would be sufficient to avoid
606 Markku-Juhani's attack. (Actually it had never occurred
607 to me that the half of 'md_local' used for chaining was the
608 half from which PRNG output bytes were taken -- I had always
609 assumed that the secret half would be used.) The second
610 measure makes sure that additional data from 'state' is never
611 mixed into 'md_local' in small portions; this heuristically
612 further strengthens the PRNG.
615 +) Speed up EVP routines.

633 *) Fix crypto/bn/asm/mips3.s.
636 *) When only the key is given to "enc", the IV is undefined. Print out
637 an error message in this case.
640 +) Added the OS2-EMX target.
641 ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
643 +) Rewrite apps to use NCONF routines instead of the old CONF. New functions
644 to support NCONF routines in extension code. New function CONF_set_nconf()
645 to allow functions which take an NCONF to also handle the old LHASH
646 structure: this means that the old CONF compatible routines can be
647 retained (in particular wrt extensions) without having to duplicate the
648 code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
651 *) Handle special case when X509_NAME is empty in X509 printing routines.
654 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
655 positive and less than q.
658 +) Enhance the general user interface with mechanisms for inner control
659 and with possibilities to have yes/no kind of prompts.
662 +) Change all calls to low level digest routines in the library and
663 applications to use EVP. Add missing calls to HMAC_cleanup() and
664 don't assume HMAC_CTX can be copied using memcpy().
665 [Verdon Walker <VWalker@novell.com>, Steve Henson]
667 +) Add the possibility to control engines through control names but with
668 arbitrary arguments instead of just a string.
669 Change the key loaders to take a UI_METHOD instead of a callback
670 function pointer. NOTE: this breaks binary compatibility with earlier
671 versions of OpenSSL [engine].
672 Adapt the nCipher code for these new conditions and add a card insertion
676 +) Enhance the general user interface with mechanisms to better support
677 dialog box interfaces, application-defined prompts, the possibility
678 to use defaults (for example default passwords from somewhere else)
679 and interrupts/cancellations.
682 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
683 used: it isn't thread safe and the add_lock_callback should handle
685 [Paul Rose <Paul.Rose@bridge.com>]
687 *) Verify that incoming data obeys the block size in
688 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
691 +) Tidy up PKCS#12 attribute handling. Add support for the CSP name
692 attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
696 [Ulf Möller, Bodo Möller]
698 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
699 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
700 when fixing the server behaviour for backwards-compatible 'client
701 hello' messages. (Note that the attack is impractical against
702 SSL 3.0 and TLS 1.0 anyway because length and version checking
703 means that the probability of guessing a valid ciphertext is
704 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
707 Before 0.9.5, the countermeasure (hide the error by generating a
708 random 'decryption result') did not work properly because
709 ERR_clear_error() was missing, meaning that SSL_get_error() would
710 detect the supposedly ignored error.
712 Both problems are now fixed.
715 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
716 (previously it was 1024).
719 +) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
720 tidy up some unnecessarily weird code in 'sk_new()').
721 [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
723 +) Change the key loading routines for ENGINEs to use the same kind
724 callback (pem_password_cb) as all other routines that need this
728 *) Fix for compatibility mode trust settings: ignore trust settings
729 unless some valid trust or reject settings are present.
732 *) Fix for blowfish EVP: its a variable length cipher.
735 +) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
736 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
737 than this minimum value is recommended.
740 +) New random seeder for OpenVMS, using the system process statistics
741 that are easily reachable.
744 +) Windows apparently can't transparently handle global
745 variables defined in DLLs. Initialisations such as:
747 const ASN1_ITEM *it = &ASN1_INTEGER_it;
749 wont compile. This is used by the any applications that need to
750 declare their own ASN1 modules. This was fixed by adding the option
751 EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
752 needed for static libraries under Win32.
755 +) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
756 setting of purpose and trust fields. New X509_STORE trust and
757 purpose functions and tidy up setting in other SSL functions.
760 +) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
761 structure. These are inherited by X509_STORE_CTX when it is
762 initialised. This allows various defaults to be set in the
763 X509_STORE structure (such as flags for CRL checking and custom
764 purpose or trust settings) for functions which only use X509_STORE_CTX
765 internally such as S/MIME.
767 Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
768 trust settings if they are not set in X509_STORE. This allows X509_STORE
769 purposes and trust (in S/MIME for example) to override any set by default.
771 Add command line options for CRL checking to smime, s_client and s_server
775 +) Initial CRL based revocation checking. If the CRL checking flag(s)
776 are set then the CRL is looked up in the X509_STORE structure and
777 its validity and signature checked, then if the certificate is found
778 in the CRL the verify fails with a revoked error.
780 Various new CRL related callbacks added to X509_STORE_CTX structure.
782 Command line options added to 'verify' application to support this.
784 This needs some additional work, such as being able to handle multiple
785 CRLs with different times, extension based lookup (rather than just
786 by subject name) and ultimately more complete V2 CRL extension
790 +) Add a general user interface API (crypto/ui/). This is designed
791 to replace things like des_read_password and friends (backward
792 compatibility functions using this new API are provided).
793 The purpose is to remove prompting functions from the DES code
794 section as well as provide for prompting through dialog boxes in
795 a window system and the like.
798 *) Fix various bugs related to DSA S/MIME verification. Handle missing
799 parameters in DSA public key structures and return an error in the
800 DSA routines if parameters are absent.
803 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
804 in the current directory if neither $RANDFILE nor $HOME was set.
805 RAND_file_name() in 0.9.6a returned NULL in this case. This has
806 caused some confusion to Windows users who haven't defined $HOME.
807 Thus RAND_file_name() is changed again: e_os.h can define a
808 DEFAULT_HOME, which will be used if $HOME is not set.
809 For Windows, we use "C:"; on other platforms, we still require
810 environment variables.
812 +) Add "ex_data" support to ENGINE so implementations can add state at a
813 per-structure level rather than having to store it globally.
816 +) Make it possible for ENGINE structures to be copied when retrieved by
817 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
818 This causes the "original" ENGINE structure to act like a template,
819 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
820 operational state can be localised to each ENGINE structure, despite the
821 fact they all share the same "methods". New ENGINE structures returned in
822 this case have no functional references and the return value is the single
823 structural reference. This matches the single structural reference returned
824 by ENGINE_by_id() normally, when it is incremented on the pre-existing
828 +) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
829 needs to match any other type at all we need to manually clear the
833 +) Changes to the "openssl engine" utility to include;
834 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
835 about an ENGINE's available control commands.
836 - executing control commands from command line arguments using the
837 '-pre' and '-post' switches. '-post' is only used if '-t' is
838 specified and the ENGINE is successfully initialised. The syntax for
839 the individual commands are colon-separated, for example;
840 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
843 +) New dynamic control command support for ENGINEs. ENGINEs can now
844 declare their own commands (numbers), names (strings), descriptions,
845 and input types for run-time discovery by calling applications. A
846 subset of these commands are implicitly classed as "executable"
847 depending on their input type, and only these can be invoked through
848 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
849 can be based on user input, config files, etc). The distinction is
850 that "executable" commands cannot return anything other than a boolean
851 result and can only support numeric or string input, whereas some
852 discoverable commands may only be for direct use through
853 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
854 pointers, or other custom uses. The "executable" commands are to
855 support parameterisations of ENGINE behaviour that can be
856 unambiguously defined by ENGINEs and used consistently across any
857 OpenSSL-based application. Commands have been added to all the
858 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
859 control over shared-library paths without source code alterations.
862 +) Changed all ENGINE implementations to dynamically allocate their
863 ENGINEs rather than declaring them statically. Apart from this being
864 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
865 this also allows the implementations to compile without using the
866 internal engine_int.h header.
869 +) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
870 'const' value. Any code that should be able to modify a RAND_METHOD
871 should already have non-const pointers to it (ie. they should only
872 modify their own ones).
875 +) Made a variety of little tweaks to the ENGINE code.
876 - "atalla" and "ubsec" string definitions were moved from header files
877 to C code. "nuron" string definitions were placed in variables
878 rather than hard-coded - allowing parameterisation of these values
879 later on via ctrl() commands.
880 - Removed unused "#if 0"'d code.
881 - Fixed engine list iteration code so it uses ENGINE_free() to release
882 structural references.
883 - Constified the RAND_METHOD element of ENGINE structures.
884 - Constified various get/set functions as appropriate and added
885 missing functions (including a catch-all ENGINE_cpy that duplicates
886 all ENGINE values onto a new ENGINE except reference counts/state).
887 - Removed NULL parameter checks in get/set functions. Setting a method
888 or function to NULL is a way of cancelling out a previously set
889 value. Passing a NULL ENGINE parameter is just plain stupid anyway
890 and doesn't justify the extra error symbols and code.
891 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
892 flags from engine_int.h to engine.h.
893 - Changed prototypes for ENGINE handler functions (init(), finish(),
894 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
897 *) Move 'if (!initialized) RAND_poll()' into regions protected by
898 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
899 having multiple threads call RAND_poll() concurrently.
902 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
903 combination of a flag and a thread ID variable.
904 Otherwise while one thread is in ssleay_rand_bytes (which sets the
905 flag), *other* threads can enter ssleay_add_bytes without obeying
906 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
907 that they do not hold after the first thread unsets add_do_not_lock).
910 +) Implement binary inversion algorithm for BN_mod_inverse in addition
911 to the algorithm using long division. The binary algorithm can be
912 used only if the modulus is odd. On 32-bit systems, it is faster
913 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
914 roughly 5-15% for 256-bit moduli), so we use it only for moduli
915 up to 450 bits. In 64-bit environments, the binary algorithm
916 appears to be advantageous for much longer moduli; here we use it
917 for moduli up to 2048 bits.
920 *) Change bctest again: '-x' expressions are not available in all
924 -) OpenSSL 0.9.6a released [5 Apr 2001]
926 *) Fix a couple of memory leaks in PKCS7_dataDecode()
927 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
929 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
930 the default extension for executables, if any. Also, make the perl
931 scripts that use symlink() to test if it really exists and use "cp"
932 if it doesn't. All this made OpenSSL compilable and installable in
936 +) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
937 could not support the combine flag in choice fields.
940 -) Fix for asn1_GetSequence() for indefinite length constructed data.
941 If SEQUENCE is length is indefinite just set c->slen to the total
942 amount of data available.
943 [Steve Henson, reported by shige@FreeBSD.org]
944 [This change does not apply to 0.9.7.]
946 *) Change bctest to avoid here-documents inside command substitution
947 (workaround for FreeBSD /bin/sh bug).
948 For compatibility with Ultrix, avoid shell functions (introduced
949 in the bctest version that searches along $PATH).
952 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
953 with des_encrypt() defined on some operating systems, like Solaris
957 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
958 On the Importance of Eliminating Errors in Cryptographic
959 Computations, J. Cryptology 14 (2001) 2, 101-119,
960 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
963 *) MIPS assembler BIGNUM division bug fix.
966 *) Disabled incorrect Alpha assembler code.
969 -) Fix PKCS#7 decode routines so they correctly update the length
970 after reading an EOC for the EXPLICIT tag.
972 [This change does not apply to 0.9.7.]
974 *) Fix bug in PKCS#12 key generation routines. This was triggered
975 if a 3DES key was generated with a 0 initial byte. Include
976 PKCS12_BROKEN_KEYGEN compilation option to retain the old
977 (but broken) behaviour.
980 *) Enhance bctest to search for a working bc along $PATH and print
982 [Tim Rice <tim@multitalents.net> via Richard Levitte]
984 +) Add a 'copy_extensions' option to the 'ca' utility. This copies
985 extensions from a certificate request to the certificate.
988 +) Allow multiple 'certopt' and 'nameopt' options to be separated
989 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
990 file: this allows the display of the certificate about to be
991 signed to be customised, to allow certain fields to be included
992 or excluded and extension details. The old system didn't display
993 multicharacter strings properly, omitted fields not in the policy
994 and couldn't display additional details such as extensions.
997 *) Fix memory leaks in err.c: free err_data string if necessary;
998 don't write to the wrong index in ERR_set_error_data.
1001 +) Function EC_POINTs_mul for multiple scalar multiplication
1002 of an arbitrary number of elliptic curve points
1003 \sum scalars[i]*points[i],
1004 optionally including the generator defined for the EC_GROUP:
1005 scalar*generator + \sum scalars[i]*points[i].
1007 EC_POINT_mul is a simple wrapper function for the typical case
1008 that the point list has just one item (besides the optional
1012 +) First EC_METHODs for curves over GF(p):
1014 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
1015 operations and provides various method functions that can also
1016 operate with faster implementations of modular arithmetic.
1018 EC_GFp_mont_method() reuses most functions that are part of
1019 EC_GFp_simple_method, but uses Montgomery arithmetic.
1021 [Bodo Moeller; point addition and point doubling
1022 implementation directly derived from source code provided by
1023 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
1025 +) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
1026 crypto/ec/ec_lib.c):
1028 Curves are EC_GROUP objects (with an optional group generator)
1029 based on EC_METHODs that are built into the library.
1031 Points are EC_POINT objects based on EC_GROUP objects.
1033 Most of the framework would be able to handle curves over arbitrary
1034 finite fields, but as there are no obvious types for fields other
1035 than GF(p), some functions are limited to that for now.
1038 +) Add the -HTTP option to s_server. It is similar to -WWW, but requires
1039 that the file contains a complete HTTP response.
1042 +) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
1043 change the def and num file printf format specifier from "%-40sXXX"
1044 to "%-39s XXX". The latter will always guarantee a space after the
1045 field while the former will cause them to run together if the field
1046 is 40 of more characters long.
1049 +) Constify the cipher and digest 'method' functions and structures
1050 and modify related functions to take constant EVP_MD and EVP_CIPHER
1054 *) Implement ssl23_peek (analogous to ssl23_read), which previously
1058 *) Replace rdtsc with _emit statements for VC++ version 5.
1059 [Jeremy Cooper <jeremy@baymoo.org>]
1061 +) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
1062 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
1065 +) Modify EVP_Digest*() routines so they now return values. Although the
1066 internal software routines can never fail additional hardware versions
1070 +) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
1072 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
1073 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
1076 ERR_R_NESTED_ASN1_ERROR
1078 ERR_R_MISSING_ASN1_EOS
1079 were 4 .. 9, conflicting with
1080 ERR_LIB_RSA (= ERR_R_RSA_LIB)
1082 ERR_LIB_PEM (= ERR_R_PEM_LIB).
1083 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
1085 Add new error code 'ERR_R_INTERNAL_ERROR'.
1088 +) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
1092 +) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
1093 sets the subject name for a new request or supersedes the
1094 subject name in a given request. Formats that can be parsed are
1095 'CN=Some Name, OU=myOU, C=IT'
1097 'CN=Some Name/OU=myOU/C=IT'.
1099 Add options '-batch' and '-verbose' to 'openssl req'.
1100 [Massimiliano Pala <madwolf@hackmasters.net>]
1102 *) Make it possible to reuse SSLv2 sessions.
1105 +) Introduce the possibility to access global variables through
1106 functions on platform were that's the best way to handle exporting
1107 global variables in shared libraries. To enable this functionality,
1108 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
1109 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
1110 is normally done by Configure or something similar).
1112 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
1113 in the source file (foo.c) like this:
1115 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
1116 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
1118 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
1119 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
1121 OPENSSL_DECLARE_GLOBAL(int,foo);
1122 #define foo OPENSSL_GLOBAL_REF(foo)
1123 OPENSSL_DECLARE_GLOBAL(double,bar);
1124 #define bar OPENSSL_GLOBAL_REF(bar)
1126 The #defines are very important, and therefore so is including the
1127 header file everywhere where the defined globals are used.
1129 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
1130 of ASN.1 items, but that structure is a bit different.
1132 The largest change is in util/mkdef.pl which has been enhanced with
1133 better and easier to understand logic to choose which symbols should
1134 go into the Windows .def files as well as a number of fixes and code
1135 cleanup (among others, algorithm keywords are now sorted
1136 lexicographically to avoid constant rewrites).
1139 *) In copy_email() check for >= 0 as a return value for
1140 X509_NAME_get_index_by_NID() since 0 is a valid index.
1141 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
1143 +) In BN_div() keep a copy of the sign of 'num' before writing the
1144 result to 'rm' because if rm==num the value will be overwritten
1145 and produce the wrong result if 'num' is negative: this caused
1146 problems with BN_mod() and BN_nnmod().
1149 +) Function OCSP_request_verify(). This checks the signature on an
1150 OCSP request and verifies the signer certificate. The signer
1151 certificate is just checked for a generic purpose and OCSP request
1155 +) Add OCSP_check_validity() function to check the validity of OCSP
1156 responses. OCSP responses are prepared in real time and may only
1157 be a few seconds old. Simply checking that the current time lies
1158 between thisUpdate and nextUpdate max reject otherwise valid responses
1159 caused by either OCSP responder or client clock inaccuracy. Instead
1160 we allow thisUpdate and nextUpdate to fall within a certain period of
1161 the current time. The age of the response can also optionally be
1162 checked. Two new options -validity_period and -status_age added to
1166 +) If signature or public key algorithm is unrecognized print out its
1167 OID rather that just UNKNOWN.
1170 *) Avoid coredump with unsupported or invalid public keys by checking if
1171 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
1172 PKCS7_verify() fails with non detached data.
1175 +) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
1176 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
1177 ID to be generated from the issuer certificate alone which can then be
1178 passed to OCSP_id_issuer_cmp().
1181 +) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
1182 ASN1 modules to export functions returning ASN1_ITEM pointers
1183 instead of the ASN1_ITEM structures themselves. This adds several
1184 new macros which allow the underlying ASN1 function/structure to
1185 be accessed transparently. As a result code should not use ASN1_ITEM
1186 references directly (such as &X509_it) but instead use the relevant
1187 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
1188 use of the new ASN1 code on platforms where exporting structures
1189 is problematical (for example in shared libraries) but exporting
1190 functions returning pointers to structures is not.
1193 +) Add support for overriding the generation of SSL/TLS session IDs.
1194 These callbacks can be registered either in an SSL_CTX or per SSL.
1195 The purpose of this is to allow applications to control, if they wish,
1196 the arbitrary values chosen for use as session IDs, particularly as it
1197 can be useful for session caching in multiple-server environments. A
1198 command-line switch for testing this (and any client code that wishes
1199 to use such a feature) has been added to "s_server".
1200 [Geoff Thorpe, Lutz Jaenicke]
1202 +) Modify mkdef.pl to recognise and parse preprocessor conditionals
1203 of the form '#if defined(...) || defined(...) || ...' and
1204 '#if !defined(...) && !defined(...) && ...'. This also avoids
1205 the growing number of special cases it was previously handling.
1208 *) Don't use getenv in library functions when run as setuid/setgid.
1209 New function OPENSSL_issetugid().
1212 +) Make all configuration macros available for application by making
1213 sure they are available in opensslconf.h, by giving them names starting
1214 with "OPENSSL_" to avoid conflicts with other packages and by making
1215 sure e_os2.h will cover all platform-specific cases together with
1217 Additionally, it is now possible to define configuration/platform-
1218 specific names (called "system identities"). In the C code, these
1219 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
1220 macro with the name beginning with "OPENSSL_SYS_", which is determined
1221 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
1225 +) New option -set_serial to 'req' and 'x509' this allows the serial
1226 number to use to be specified on the command line. Previously self
1227 signed certificates were hard coded with serial number 0 and the
1228 CA options of 'x509' had to use a serial number in a file which was
1232 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
1233 due to incorrect handling of multi-threading:
1235 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
1237 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
1239 3. Count how many times MemCheck_off() has been called so that
1240 nested use can be treated correctly. This also avoids
1241 inband-signalling in the previous code (which relied on the
1242 assumption that thread ID 0 is impossible).
1245 +) New options to 'ca' utility to support V2 CRL entry extensions.
1246 Currently CRL reason, invalidity date and hold instruction are
1247 supported. Add new CRL extensions to V3 code and some new objects.
1250 *) Add "-rand" option also to s_client and s_server.
1253 +) New function EVP_CIPHER_CTX_set_padding() this is used to
1254 disable standard block padding (aka PKCS#5 padding) in the EVP
1255 API, which was previously mandatory. This means that the data is
1256 not padded in any way and so the total length much be a multiple
1257 of the block size, otherwise an error occurs.
1260 +) Initial (incomplete) OCSP SSL support.
1263 *) Fix CPU detection on Irix 6.x.
1264 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
1265 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
1267 +) New function OCSP_parse_url(). This splits up a URL into its host,
1268 port and path components: primarily to parse OCSP URLs. New -url
1269 option to ocsp utility.
1272 +) New nonce behavior. The return value of OCSP_check_nonce() now
1273 reflects the various checks performed. Applications can decide
1274 whether to tolerate certain situations such as an absent nonce
1275 in a response when one was present in a request: the ocsp application
1276 just prints out a warning. New function OCSP_add1_basic_nonce()
1277 this is to allow responders to include a nonce in a response even if
1278 the request is nonce-less.
1281 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
1284 [This change does not apply to 0.9.7.]
1286 *) Use the cached encoding of an X509_NAME structure rather than
1287 copying it. This is apparently the reason for the libsafe "errors"
1288 but the code is actually correct.
1291 +) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
1292 skipped when using openssl x509 multiple times on a single input file,
1293 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
1296 +) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
1297 set string type: to handle setting ASN1_TIME structures. Fix ca
1298 utility to correctly initialize revocation date of CRLs.
1301 +) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
1302 the clients preferred ciphersuites and rather use its own preferences.
1303 Should help to work around M$ SGC (Server Gated Cryptography) bug in
1304 Internet Explorer by ensuring unchanged hash method during stepup.
1305 (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
1308 +) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
1309 to aes and add a new 'exist' option to print out symbols that don't
1313 +) Additional options to ocsp utility to allow flags to be set and
1314 additional certificates supplied.
1317 +) Add the option -VAfile to 'openssl ocsp', so the user can give the
1318 OCSP client a number of certificate to only verify the response
1322 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
1323 Bleichenbacher's DSA attack.
1324 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
1325 to be set and top=0 forces the highest bit to be set; top=-1 is new
1326 and leaves the highest bit random.
1327 [Ulf Moeller, Bodo Moeller]
1329 +) Update Rijndael code to version 3.0 and change EVP AES ciphers to
1330 handle the new API. Currently only ECB, CBC modes supported. Add new
1331 AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
1332 for TLS" draft-ietf-tls-ciphersuite-03.txt.
1333 [Ben Laurie, Steve Henson]
1335 *) In the NCONF_...-based implementations for CONF_... queries
1336 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
1337 a temporary CONF structure with the data component set to NULL
1338 (which gives segmentation faults in lh_retrieve).
1339 Instead, use NULL for the CONF pointer in CONF_get_string and
1340 CONF_get_number (which may use environment variables) and directly
1341 return NULL from CONF_get_section.
1344 *) Fix potential buffer overrun for EBCDIC.
1347 +) New function OCSP_copy_nonce() to copy nonce value (if present) from
1348 request to response.
1351 +) Functions for OCSP responders. OCSP_request_onereq_count(),
1352 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
1353 extract information from a certificate request. OCSP_response_create()
1354 creates a response and optionally adds a basic response structure.
1355 OCSP_basic_add1_status() adds a complete single response to a basic
1356 response and returns the OCSP_SINGLERESP structure just added (to allow
1357 extensions to be included for example). OCSP_basic_add1_cert() adds a
1358 certificate to a basic response and OCSP_basic_sign() signs a basic
1359 response with various flags. New helper functions ASN1_TIME_check()
1360 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
1361 (converts ASN1_TIME to GeneralizedTime).
1364 +) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
1365 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
1366 structure from a certificate. X509_pubkey_digest() digests the public_key
1367 contents: this is used in various key identifiers.
1370 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
1371 keyUsage if basicConstraints absent for a CA.
1374 *) Make SMIME_write_PKCS7() write mail header values with a format that
1375 is more generally accepted (no spaces before the semicolon), since
1376 some programs can't parse those values properly otherwise. Also make
1377 sure BIO's that break lines after each write do not create invalid
1381 +) Make sk_sort() tolerate a NULL argument.
1382 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
1384 +) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
1385 passed by the function are trusted implicitly. If any of them signed the
1386 response then it is assumed to be valid and is not verified.
1389 -) Make the CRL encoding routines work with empty SEQUENCE OF. The
1390 macros previously used would not encode an empty SEQUENCE OF
1391 and break the signature.
1393 [This change does not apply to 0.9.7.]
1395 *) Zero the premaster secret after deriving the master secret in
1399 +) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
1400 to data. This was previously part of the PKCS7 ASN1 code. This
1401 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
1402 [Steve Henson, reported by Kenneth R. Robinette
1403 <support@securenetterm.com>]
1405 +) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
1406 routines: without these tracing memory leaks is very painful.
1407 Fix leaks in PKCS12 and PKCS7 routines.
1410 *) Add some EVP_add_digest_alias registrations (as found in
1411 OpenSSL_add_all_digests()) to SSL_library_init()
1412 aka OpenSSL_add_ssl_algorithms(). This provides improved
1413 compatibility with peers using X.509 certificates
1414 with unconventional AlgorithmIdentifier OIDs.
1417 *) Fix for Irix with NO_ASM.
1418 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
1420 *) ./config script fixes.
1421 [Ulf Moeller, Richard Levitte]
1423 +) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
1424 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
1425 effectively meant GeneralizedTime would never be used. Now it
1426 is initialised to -1 but X509_time_adj() now has to check the value
1427 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
1428 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
1429 [Steve Henson, reported by Kenneth R. Robinette
1430 <support@securenetterm.com>]
1432 +) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
1433 result in a zero length in the ASN1_INTEGER structure which was
1434 not consistent with the structure when d2i_ASN1_INTEGER() was used
1435 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
1436 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
1437 where it did not print out a minus for negative ASN1_INTEGER.
1440 *) Fix 'openssl passwd -1'.
1443 +) Add summary printout to ocsp utility. The various functions which
1444 convert status values to strings have been renamed to:
1445 OCSP_response_status_str(), OCSP_cert_status_str() and
1446 OCSP_crl_reason_str() and are no longer static. New options
1447 to verify nonce values and to disable verification. OCSP response
1448 printout format cleaned up.
1451 +) Add additional OCSP certificate checks. These are those specified
1452 in RFC2560. This consists of two separate checks: the CA of the
1453 certificate being checked must either be the OCSP signer certificate
1454 or the issuer of the OCSP signer certificate. In the latter case the
1455 OCSP signer certificate must contain the OCSP signing extended key
1456 usage. This check is performed by attempting to match the OCSP
1457 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
1458 in the OCSP_CERTID structures of the response.
1461 +) Initial OCSP certificate verification added to OCSP_basic_verify()
1462 and related routines. This uses the standard OpenSSL certificate
1463 verify routines to perform initial checks (just CA validity) and
1464 to obtain the certificate chain. Then additional checks will be
1465 performed on the chain. Currently the root CA is checked to see
1466 if it is explicitly trusted for OCSP signing. This is used to set
1467 a root CA as a global signing root: that is any certificate that
1468 chains to that CA is an acceptable OCSP signing certificate.
1471 +) New '-extfile ...' option to 'openssl ca' for reading X.509v3
1472 extensions from a separate configuration file.
1473 As when reading extensions from the main configuration file,
1474 the '-extensions ...' option may be used for specifying the
1476 [Massimiliano Pala <madwolf@comune.modena.it>]
1478 *) Change PKCS12_key_gen_asc() so it can cope with non null
1479 terminated strings whose length is passed in the passlen
1480 parameter, for example from PEM callbacks. This was done
1481 by adding an extra length parameter to asc2uni().
1482 [Steve Henson, reported by <oddissey@samsung.co.kr>]
1484 +) New OCSP utility. Allows OCSP requests to be generated or
1485 read. The request can be sent to a responder and the output
1486 parsed, outputed or printed in text form. Not complete yet:
1487 still needs to check the OCSP response validity.
1490 +) New subcommands for 'openssl ca':
1491 'openssl ca -status <serial>' prints the status of the cert with
1492 the given serial number (according to the index file).
1493 'openssl ca -updatedb' updates the expiry status of certificates
1495 [Massimiliano Pala <madwolf@comune.modena.it>]
1497 +) New '-newreq-nodes' command option to CA.pl. This is like
1498 '-newreq', but calls 'openssl req' with the '-nodes' option
1499 so that the resulting key is not encrypted.
1500 [Damien Miller <djm@mindrot.org>]
1502 +) New configuration for the GNU Hurd.
1503 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
1505 +) Initial code to implement OCSP basic response verify. This
1506 is currently incomplete. Currently just finds the signer's
1507 certificate and verifies the signature on the response.
1510 +) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
1511 value of OPENSSLDIR. This is available via the new '-d' option
1512 to 'openssl version', and is also included in 'openssl version -a'.
1515 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
1516 call failed, free the DSA structure.
1519 +) Allowing defining memory allocation callbacks that will be given
1520 file name and line number information in additional arguments
1521 (a const char* and an int). The basic functionality remains, as
1522 well as the original possibility to just replace malloc(),
1523 realloc() and free() by functions that do not know about these
1524 additional arguments. To register and find out the current
1525 settings for extended allocation functions, the following
1526 functions are provided:
1528 CRYPTO_set_mem_ex_functions
1529 CRYPTO_set_locked_mem_ex_functions
1530 CRYPTO_get_mem_ex_functions
1531 CRYPTO_get_locked_mem_ex_functions
1533 These work the same way as CRYPTO_set_mem_functions and friends.
1534 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
1535 extended allocation function is enabled.
1536 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
1537 a conventional allocation function is enabled.
1538 [Richard Levitte, Bodo Moeller]
1540 *) Fix to uni2asc() to cope with zero length Unicode strings.
1541 These are present in some PKCS#12 files.
1544 +) Finish off removing the remaining LHASH function pointer casts.
1545 There should no longer be any prototype-casting required when using
1546 the LHASH abstraction, and any casts that remain are "bugs". See
1547 the callback types and macros at the head of lhash.h for details
1548 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
1551 +) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
1552 If /dev/[u]random devices are not available or do not return enough
1553 entropy, EGD style sockets (served by EGD or PRNGD) will automatically
1555 The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
1556 /etc/entropy will be queried once each in this sequence, quering stops
1557 when enough entropy was collected without querying more sockets.
1560 +) Change the Unix RAND_poll() variant to be able to poll several
1561 random devices, as specified by DEVRANDOM, until a sufficient amount
1562 of data has been collected. We spend at most 10 ms on each file
1563 (select timeout) and read in non-blocking mode. DEVRANDOM now
1564 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
1565 (previously it was just the string "/dev/urandom"), so on typical
1566 platforms the 10 ms delay will never occur.
1567 Also separate out the Unix variant to its own file, rand_unix.c.
1568 For VMS, there's a currently-empty rand_vms.c.
1571 +) Move OCSP client related routines to ocsp_cl.c. These
1572 provide utility functions which an application needing
1573 to issue a request to an OCSP responder and analyse the
1574 response will typically need: as opposed to those which an
1575 OCSP responder itself would need which will be added later.
1577 OCSP_request_sign() signs an OCSP request with an API similar
1578 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
1579 response. OCSP_response_get1_basic() extracts basic response
1580 from response. OCSP_resp_find_status(): finds and extracts status
1581 information from an OCSP_CERTID structure (which will be created
1582 when the request structure is built). These are built from lower
1583 level functions which work on OCSP_SINGLERESP structures but
1584 wont normally be used unless the application wishes to examine
1585 extensions in the OCSP response for example.
1587 Replace nonce routines with a pair of functions.
1588 OCSP_request_add1_nonce() adds a nonce value and optionally
1589 generates a random value. OCSP_check_nonce() checks the
1590 validity of the nonce in an OCSP response.
1593 +) Change function OCSP_request_add() to OCSP_request_add0_id().
1594 This doesn't copy the supplied OCSP_CERTID and avoids the
1595 need to free up the newly created id. Change return type
1596 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
1597 This can then be used to add extensions to the request.
1598 Deleted OCSP_request_new(), since most of its functionality
1599 is now in OCSP_REQUEST_new() (and the case insensitive name
1600 clash) apart from the ability to set the request name which
1601 will be added elsewhere.
1604 +) Update OCSP API. Remove obsolete extensions argument from
1605 various functions. Extensions are now handled using the new
1606 OCSP extension code. New simple OCSP HTTP function which
1607 can be used to send requests and parse the response.
1610 +) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
1611 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
1612 uses the special reorder version of SET OF to sort the attributes
1613 and reorder them to match the encoded order. This resolves a long
1614 standing problem: a verify on a PKCS7 structure just after signing
1615 it used to fail because the attribute order did not match the
1616 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
1617 it uses the received order. This is necessary to tolerate some broken
1618 software that does not order SET OF. This is handled by encoding
1619 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
1620 to produce the required SET OF.
1623 +) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
1624 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
1625 files to get correct declarations of the ASN.1 item variables.
1628 +) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
1629 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
1630 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
1631 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
1632 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
1633 ASN1_ITEM and no wrapper functions.
1636 +) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
1637 replace the old function pointer based I/O routines. Change most of
1638 the *_d2i_bio() and *_d2i_fp() functions to use these.
1641 +) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
1642 lines, recognice more "algorithms" that can be deselected, and make
1643 it complain about algorithm deselection that isn't recognised.
1646 +) New ASN1 functions to handle dup, sign, verify, digest, pack and
1647 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
1648 to use new functions. Add NO_ASN1_OLD which can be set to remove
1649 some old style ASN1 functions: this can be used to determine if old
1650 code will still work when these eventually go away.
1653 +) New extension functions for OCSP structures, these follow the
1654 same conventions as certificates and CRLs.
1657 +) New function X509V3_add1_i2d(). This automatically encodes and
1658 adds an extension. Its behaviour can be customised with various
1659 flags to append, replace or delete. Various wrappers added for
1660 certifcates and CRLs.
1663 +) Fix to avoid calling the underlying ASN1 print routine when
1664 an extension cannot be parsed. Correct a typo in the
1665 OCSP_SERVICELOC extension. Tidy up print OCSP format.
1668 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
1669 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
1670 when writing a 32767 byte record.
1671 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
1673 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
1674 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
1676 (RSA objects have a reference count access to which is protected
1677 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
1678 so they are meant to be shared between threads.)
1679 [Bodo Moeller, Geoff Thorpe; original patch submitted by
1680 "Reddie, Steven" <Steven.Reddie@ca.com>]
1682 +) Make mkdef.pl parse some of the ASN1 macros and add apropriate
1683 entries for variables.
1686 *) Fix a deadlock in CRYPTO_mem_leaks().
1689 +) Add functionality to apps/openssl.c for detecting locking
1690 problems: As the program is single-threaded, all we have
1691 to do is register a locking callback using an array for
1692 storing which locks are currently held by the program.
1695 +) Use a lock around the call to CRYPTO_get_ex_new_index() in
1696 SSL_get_ex_data_X509_STORE_idx(), which is used in
1697 ssl_verify_cert_chain() and thus can be called at any time
1698 during TLS/SSL handshakes so that thread-safety is essential.
1699 Unfortunately, the ex_data design is not at all suited
1700 for multi-threaded use, so it probably should be abolished.
1703 +) Added Broadcom "ubsec" ENGINE to OpenSSL.
1704 [Broadcom, tweaked and integrated by Geoff Thorpe]
1706 +) Move common extension printing code to new function
1707 X509V3_print_extensions(). Reorganise OCSP print routines and
1708 implement some needed OCSP ASN1 functions. Add OCSP extensions.
1711 +) New function X509_signature_print() to remove duplication in some
1715 +) Add a special meaning when SET OF and SEQUENCE OF flags are both
1716 set (this was treated exactly the same as SET OF previously). This
1717 is used to reorder the STACK representing the structure to match the
1718 encoding. This will be used to get round a problem where a PKCS7
1719 structure which was signed could not be verified because the STACK
1720 order did not reflect the encoded order.
1723 +) Reimplement the OCSP ASN1 module using the new code.
1726 +) Update the X509V3 code to permit the use of an ASN1_ITEM structure
1727 for its ASN1 operations. The old style function pointers still exist
1728 for now but they will eventually go away.
1731 +) Merge in replacement ASN1 code from the ASN1 branch. This almost
1732 completely replaces the old ASN1 functionality with a table driven
1733 encoder and decoder which interprets an ASN1_ITEM structure describing
1734 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
1735 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
1736 has also been converted to the new form.
1739 +) Change BN_mod_exp_recp so that negative moduli are tolerated
1740 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
1741 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
1742 for negative moduli.
1745 +) Fix BN_uadd and BN_usub: Always return non-negative results instead
1746 of not touching the result's sign bit.
1749 +) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
1753 +) Changed the LHASH code to use prototypes for callbacks, and created
1754 macros to declare and implement thin (optionally static) functions
1755 that provide type-safety and avoid function pointer casting for the
1756 type-specific callbacks.
1759 *) Use better test patterns in bntest.
1762 +) Added Kerberos Cipher Suites to be used with TLS, as written in
1764 [Veers Staats <staatsvr@asc.hpc.mil>,
1765 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
1767 *) rand_win.c fix for Borland C.
1770 *) BN_rshift bugfix for n == 0.
1773 +) Reformat the FAQ so the different questions and answers can be divided
1774 in sections depending on the subject.
1777 +) Have the zlib compression code load ZLIB.DLL dynamically under
1781 +) New function BN_mod_sqrt for computing square roots modulo a prime
1782 (using the probabilistic Tonelli-Shanks algorithm unless
1783 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
1784 be handled deterministically).
1785 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
1787 *) Add a 'bctest' script that checks for some known 'bc' bugs
1788 so that 'make test' does not abort just because 'bc' is broken.
1791 *) Store verify_result within SSL_SESSION also for client side to
1792 avoid potential security hole. (Re-used sessions on the client side
1793 always resulted in verify_result==X509_V_OK, not using the original
1794 result of the server certificate verification.)
1797 +) Make BN_mod_inverse faster by explicitly handling small quotients
1798 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
1799 512 bits], about 30% for larger ones [1024 or 2048 bits].)
1802 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
1803 SSL3_RT_APPLICATION_DATA, return 0.
1804 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
1808 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
1809 releases, have been re-implemented by renaming the previous
1810 implementations of ssl2_read and ssl3_read to ssl2_read_internal
1811 and ssl3_read_internal, respectively, and adding 'peek' parameters
1812 to them. The new ssl[23]_{read,peek} functions are calls to
1813 ssl[23]_read_internal with the 'peek' flag set appropriately.
1814 A 'peek' parameter has also been added to ssl3_read_bytes, which
1815 does the actual work for ssl3_read_internal.
1818 +) New function BN_kronecker.
1821 +) Fix BN_gcd so that it works on negative inputs; the result is
1822 positive unless both parameters are zero.
1823 Previously something reasonably close to an infinite loop was
1824 possible because numbers could be growing instead of shrinking
1825 in the implementation of Euclid's algorithm.
1828 +) Fix BN_is_word() and BN_is_one() macros to take into account the
1829 sign of the number in question.
1831 Fix BN_is_word(a,w) to work correctly for w == 0.
1833 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
1834 because its test if the absolute value of 'a' equals 'w'.
1835 Note that BN_abs_is_word does *not* handle w == 0 reliably;
1836 it exists mostly for use in the implementations of BN_is_zero(),
1837 BN_is_one(), and BN_is_word().
1840 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
1841 the method-specific "init()" handler. Also clean up ex_data after
1842 calling the method-specific "finish()" handler. Previously, this was
1843 happening the other way round.
1846 +) New function BN_swap.
1849 +) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
1850 the exponentiation functions are more likely to produce reasonable
1851 results on negative inputs.
1854 +) Change BN_mod_mul so that the result is always non-negative.
1855 Previously, it could be negative if one of the factors was negative;
1856 I don't think anyone really wanted that behaviour.
1859 +) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
1860 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
1861 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
1862 and add new functions:
1871 BN_mod_lshift1_quick
1875 These functions always generate non-negative results.
1877 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
1878 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
1880 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
1881 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
1882 be reduced modulo m.
1883 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
1885 +) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
1886 was actually never needed) and in BN_mul(). The removal in BN_mul()
1887 required a small change in bn_mul_part_recursive() and the addition
1888 of the functions bn_cmp_part_words(), bn_sub_part_words() and
1889 bn_add_part_words(), which do the same thing as bn_cmp_words(),
1890 bn_sub_words() and bn_add_words() except they take arrays with
1894 +) In 'openssl passwd', verify passwords read from the terminal
1895 unless the '-salt' option is used (which usually means that
1896 verification would just waste user's time since the resulting
1897 hash is going to be compared with some given password hash)
1898 or the new '-noverify' option is used.
1900 This is an incompatible change, but it does not affect
1901 non-interactive use of 'openssl passwd' (passwords on the command
1902 line, '-stdin' option, '-in ...' option) and thus should not
1906 +) Remove all references to RSAref, since there's no more need for it.
1909 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
1910 The previous value, 12, was not always sufficient for BN_mod_exp().
1913 +) Make DSO load along a path given through an environment variable
1914 (SHLIB_PATH) with shl_load().
1917 +) Constify the ENGINE code as a result of BIGNUM constification.
1918 Also constify the RSA code and most things related to it. In a
1919 few places, most notable in the depth of the ASN.1 code, ugly
1920 casts back to non-const were required (to be solved at a later
1924 +) Make it so the openssl application has all engines loaded by default.
1927 +) Constify the BIGNUM routines a little more.
1930 *) Make sure that shared libraries get the internal name engine with
1931 the full version number and not just 0. This should mark the
1932 shared libraries as not backward compatible. Of course, this should
1933 be changed again when we can guarantee backward binary compatibility.
1936 +) Add the following functions:
1938 ENGINE_load_cswift()
1940 ENGINE_load_atalla()
1942 ENGINE_load_builtin_engines()
1944 That way, an application can itself choose if external engines that
1945 are built-in in OpenSSL shall ever be used or not. The benefit is
1946 that applications won't have to be linked with libdl or other dso
1947 libraries unless it's really needed.
1949 Changed 'openssl engine' to load all engines on demand.
1950 Changed the engine header files to avoid the duplication of some
1951 declarations (they differed!).
1954 +) 'openssl engine' can now list capabilities.
1957 +) Better error reporting in 'openssl engine'.
1960 +) Never call load_dh_param(NULL) in s_server.
1963 +) Add engine application. It can currently list engines by name and
1964 identity, and test if they are actually available.
1967 +) Improve RPM specification file by forcing symbolic linking and making
1968 sure the installed documentation is also owned by root.root.
1969 [Damien Miller <djm@mindrot.org>]
1971 +) Give the OpenSSL applications more possibilities to make use of
1972 keys (public as well as private) handled by engines.
1975 +) Add OCSP code that comes from CertCo.
1978 +) Add VMS support for the Rijndael code.
1981 +) Added untested support for Nuron crypto accelerator.
1984 +) Add support for external cryptographic devices. This code was
1985 previously distributed separately as the "engine" branch.
1986 [Geoff Thorpe, Richard Levitte]
1988 +) Rework the filename-translation in the DSO code. It is now possible to
1989 have far greater control over how a "name" is turned into a filename
1990 depending on the operating environment and any oddities about the
1991 different shared library filenames on each system.
1994 +) Support threads on FreeBSD-elf in Configure.
1997 +) Fix for SHA1 assembly problem with MASM: it produces
1998 warnings about corrupt line number information when assembling
1999 with debugging information. This is caused by the overlapping
2001 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
2004 NCONF_get_number() has no error checking at all. As a replacement,
2005 NCONF_get_number_e() is defined (_e for "error checking") and is
2006 promoted strongly. The old NCONF_get_number is kept around for
2007 binary backward compatibility.
2008 Make it possible for methods to load from something other than a BIO,
2009 by providing a function pointer that is given a name instead of a BIO.
2010 For example, this could be used to load configuration data from an
2014 *) Fix typo in get_cert_by_subject() in by_dir.c
2015 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
2017 *) Rework the system to generate shared libraries:
2019 - Make note of the expected extension for the shared libraries and
2020 if there is a need for symbolic links from for example libcrypto.so.0
2021 to libcrypto.so.0.9.7. There is extended info in Configure for
2024 - Make as few rebuilds of the shared libraries as possible.
2026 - Still avoid linking the OpenSSL programs with the shared libraries.
2028 - When installing, install the shared libraries separately from the
2032 +) Fix for non blocking accept BIOs. Added new I/O special reason
2033 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
2034 with non blocking I/O was not possible because no retry code was
2035 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
2039 +) Added the beginnings of Rijndael support.
2042 +) Fix for bug in DirectoryString mask setting. Add support for
2043 X509_NAME_print_ex() in 'req' and X509_print_ex() function
2044 to allow certificate printing to more controllable, additional
2045 'certopt' option to 'x509' to allow new printing options to be
2049 +) Clean old EAY MD5 hack from e_os.h.
2052 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
2054 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
2055 and not in SSL_clear because the latter is also used by the
2056 accept/connect functions; previously, the settings made by
2057 SSL_set_read_ahead would be lost during the handshake.
2058 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
2060 *) Correct util/mkdef.pl to be selective about disabled algorithms.
2061 Previously, it would create entries for disableed algorithms no
2065 *) Added several new manual pages for SSL_* function.
2068 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
2070 *) In ssl23_get_client_hello, generate an error message when faced
2071 with an initial SSL 3.0/TLS record that is too small to contain the
2072 first two bytes of the ClientHello message, i.e. client_version.
2073 (Note that this is a pathologic case that probably has never happened
2074 in real life.) The previous approach was to use the version number
2075 from the record header as a substitute; but our protocol choice
2076 should not depend on that one because it is not authenticated
2077 by the Finished messages.
2080 *) More robust randomness gathering functions for Windows.
2081 [Jeffrey Altman <jaltman@columbia.edu>]
2083 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
2084 not set then we don't setup the error code for issuer check errors
2085 to avoid possibly overwriting other errors which the callback does
2086 handle. If an application does set the flag then we assume it knows
2087 what it is doing and can handle the new informational codes
2091 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
2092 a general "ANY" type, as such it should be able to decode anything
2093 including tagged types. However it didn't check the class so it would
2094 wrongly interpret tagged types in the same way as their universal
2095 counterpart and unknown types were just rejected. Changed so that the
2096 tagged and unknown types are handled in the same way as a SEQUENCE:
2097 that is the encoding is stored intact. There is also a new type
2098 "V_ASN1_OTHER" which is used when the class is not universal, in this
2099 case we have no idea what the actual type is so we just lump them all
2103 *) On VMS, stdout may very well lead to a file that is written to
2104 in a record-oriented fashion. That means that every write() will
2105 write a separate record, which will be read separately by the
2106 programs trying to read from it. This can be very confusing.
2108 The solution is to put a BIO filter in the way that will buffer
2109 text until a linefeed is reached, and then write everything a
2110 line at a time, so every record written will be an actual line,
2111 not chunks of lines and not (usually doesn't happen, but I've
2112 seen it once) several lines in one record. BIO_f_linebuffer() is
2115 Currently, it's a VMS-only method, because that's where it has
2116 been tested well enough.
2119 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
2120 it can return incorrect results.
2121 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
2122 but it was in 0.9.6-beta[12].)
2125 *) Disable the check for content being present when verifying detached
2126 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
2127 include zero length content when signing messages.
2130 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
2131 BIO_ctrl (for BIO pairs).
2134 *) Add DSO method for VMS.
2137 *) Bug fix: Montgomery multiplication could produce results with the
2141 *) Add RPM specification openssl.spec and modify it to build three
2142 packages. The default package contains applications, application
2143 documentation and run-time libraries. The devel package contains
2144 include files, static libraries and function documentation. The
2145 doc package contains the contents of the doc directory. The original
2146 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
2149 *) Add a large number of documentation files for many SSL routines.
2150 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
2152 *) Add a configuration entry for Sony News 4.
2153 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
2155 *) Don't set the two most significant bits to one when generating a
2156 random number < q in the DSA library.
2159 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
2160 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
2161 the underlying transport is blocking) if a handshake took place.
2162 (The default behaviour is needed by applications such as s_client
2163 and s_server that use select() to determine when to use SSL_read;
2164 but for applications that know in advance when to expect data, it
2165 just makes things more complicated.)
2168 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
2172 *) Add a few more EBCDIC conditionals that make `req' and `x509'
2173 work better on such systems.
2174 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2176 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
2177 Update PKCS12_parse() so it copies the friendlyName and the
2178 keyid to the certificates aux info.
2181 *) Fix bug in PKCS7_verify() which caused an infinite loop
2182 if there was more than one signature.
2183 [Sven Uszpelkat <su@celocom.de>]
2185 *) Major change in util/mkdef.pl to include extra information
2186 about each symbol, as well as presentig variables as well
2187 as functions. This change means that there's n more need
2188 to rebuild the .num files when some algorithms are excluded.
2191 *) Allow the verify time to be set by an application,
2192 rather than always using the current time.
2195 *) Phase 2 verify code reorganisation. The certificate
2196 verify code now looks up an issuer certificate by a
2197 number of criteria: subject name, authority key id
2198 and key usage. It also verifies self signed certificates
2199 by the same criteria. The main comparison function is
2200 X509_check_issued() which performs these checks.
2202 Lot of changes were necessary in order to support this
2203 without completely rewriting the lookup code.
2205 Authority and subject key identifier are now cached.
2207 The LHASH 'certs' is X509_STORE has now been replaced
2208 by a STACK_OF(X509_OBJECT). This is mainly because an
2209 LHASH can't store or retrieve multiple objects with
2210 the same hash value.
2212 As a result various functions (which were all internal
2213 use only) have changed to handle the new X509_STORE
2214 structure. This will break anything that messed round
2215 with X509_STORE internally.
2217 The functions X509_STORE_add_cert() now checks for an
2218 exact match, rather than just subject name.
2220 The X509_STORE API doesn't directly support the retrieval
2221 of multiple certificates matching a given criteria, however
2222 this can be worked round by performing a lookup first
2223 (which will fill the cache with candidate certificates)
2224 and then examining the cache for matches. This is probably
2225 the best we can do without throwing out X509_LOOKUP
2226 entirely (maybe later...).
2228 The X509_VERIFY_CTX structure has been enhanced considerably.
2230 All certificate lookup operations now go via a get_issuer()
2231 callback. Although this currently uses an X509_STORE it
2232 can be replaced by custom lookups. This is a simple way
2233 to bypass the X509_STORE hackery necessary to make this
2234 work and makes it possible to use more efficient techniques
2235 in future. A very simple version which uses a simple
2236 STACK for its trusted certificate store is also provided
2237 using X509_STORE_CTX_trusted_stack().
2239 The verify_cb() and verify() callbacks now have equivalents
2240 in the X509_STORE_CTX structure.
2242 X509_STORE_CTX also has a 'flags' field which can be used
2243 to customise the verify behaviour.
2246 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
2247 excludes S/MIME capabilities.
2250 *) When a certificate request is read in keep a copy of the
2251 original encoding of the signed data and use it when outputing
2252 again. Signatures then use the original encoding rather than
2253 a decoded, encoded version which may cause problems if the
2254 request is improperly encoded.
2257 *) For consistency with other BIO_puts implementations, call
2258 buffer_write(b, ...) directly in buffer_puts instead of calling
2261 In BIO_puts, increment b->num_write as in BIO_write.
2262 [Peter.Sylvester@EdelWeb.fr]
2264 *) Fix BN_mul_word for the case where the word is 0. (We have to use
2265 BN_zero, we may not return a BIGNUM with an array consisting of
2269 *) Avoid calling abort() from within the library when problems are
2270 detected, except if preprocessor symbols have been defined
2271 (such as REF_CHECK, BN_DEBUG etc.).
2274 *) New openssl application 'rsautl'. This utility can be
2275 used for low level RSA operations. DER public key
2276 BIO/fp routines also added.
2279 *) New Configure entry and patches for compiling on QNX 4.
2280 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
2282 *) A demo state-machine implementation was sponsored by
2283 Nuron (http://www.nuron.com/) and is now available in
2284 demos/state_machine.
2287 *) New options added to the 'dgst' utility for signature
2288 generation and verification.
2291 *) Unrecognized PKCS#7 content types are now handled via a
2292 catch all ASN1_TYPE structure. This allows unsupported
2293 types to be stored as a "blob" and an application can
2294 encode and decode it manually.
2297 *) Fix various signed/unsigned issues to make a_strex.c
2299 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
2301 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
2302 length if passed a buffer. ASN1_INTEGER_to_BN failed
2303 if passed a NULL BN and its argument was negative.
2304 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
2306 *) Modification to PKCS#7 encoding routines to output definite
2307 length encoding. Since currently the whole structures are in
2308 memory there's not real point in using indefinite length
2309 constructed encoding. However if OpenSSL is compiled with
2310 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
2313 *) Added BIO_vprintf() and BIO_vsnprintf().
2316 *) Added more prefixes to parse for in the the strings written
2317 through a logging bio, to cover all the levels that are available
2318 through syslog. The prefixes are now:
2320 PANIC, EMERG, EMR => LOG_EMERG
2321 ALERT, ALR => LOG_ALERT
2322 CRIT, CRI => LOG_CRIT
2323 ERROR, ERR => LOG_ERR
2324 WARNING, WARN, WAR => LOG_WARNING
2325 NOTICE, NOTE, NOT => LOG_NOTICE
2326 INFO, INF => LOG_INFO
2327 DEBUG, DBG => LOG_DEBUG
2329 and as before, if none of those prefixes are present at the
2330 beginning of the string, LOG_ERR is chosen.
2332 On Win32, the LOG_* levels are mapped according to this:
2334 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
2335 LOG_WARNING => EVENTLOG_WARNING_TYPE
2336 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
2340 *) Made it possible to reconfigure with just the configuration
2341 argument "reconf" or "reconfigure". The command line arguments
2342 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
2343 and are retrieved from there when reconfiguring.
2347 [Assar Westerlund <assar@sics.se>, Richard Levitte]
2349 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
2352 *) The obj_dat.pl script was messing up the sorting of object
2353 names. The reason was that it compared the quoted version
2354 of strings as a result "OCSP" > "OCSP Signing" because
2355 " > SPACE. Changed script to store unquoted versions of
2356 names and add quotes on output. It was also omitting some
2357 names from the lookup table if they were given a default
2358 value (that is if SN is missing it is given the same
2359 value as LN and vice versa), these are now added on the
2360 grounds that if an object has a name we should be able to
2361 look it up. Finally added warning output when duplicate
2362 short or long names are found.
2365 *) Changes needed for Tandem NSK.
2366 [Scott Uroff <scott@xypro.com>]
2368 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
2369 RSA_padding_check_SSLv23(), special padding was never detected
2370 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
2371 version rollback attacks was not effective.
2373 In s23_clnt.c, don't use special rollback-attack detection padding
2374 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
2375 client; similarly, in s23_srvr.c, don't do the rollback check if
2376 SSL 2.0 is the only protocol enabled in the server.
2379 *) Make it possible to get hexdumps of unprintable data with 'openssl
2380 asn1parse'. By implication, the functions ASN1_parse_dump() and
2381 BIO_dump_indent() are added.
2384 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
2385 these print out strings and name structures based on various
2386 flags including RFC2253 support and proper handling of
2387 multibyte characters. Added options to the 'x509' utility
2388 to allow the various flags to be set.
2391 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
2392 Also change the functions X509_cmp_current_time() and
2393 X509_gmtime_adj() work with an ASN1_TIME structure,
2394 this will enable certificates using GeneralizedTime in validity
2395 dates to be checked.
2398 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
2399 negative public key encodings) on by default,
2400 NO_NEG_PUBKEY_BUG can be set to disable it.
2403 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
2404 content octets. An i2c_ASN1_OBJECT is unnecessary because
2405 the encoding can be trivially obtained from the structure.
2408 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
2409 not read locks (CRYPTO_r_[un]lock).
2412 *) A first attempt at creating official support for shared
2413 libraries through configuration. I've kept it so the
2414 default is static libraries only, and the OpenSSL programs
2415 are always statically linked for now, but there are
2416 preparations for dynamic linking in place.
2417 This has been tested on Linux and Tru64.
2420 *) Randomness polling function for Win9x, as described in:
2421 Peter Gutmann, Software Generation of Practically Strong
2425 *) Fix so PRNG is seeded in req if using an already existing
2429 *) New options to smime application. -inform and -outform
2430 allow alternative formats for the S/MIME message including
2431 PEM and DER. The -content option allows the content to be
2432 specified separately. This should allow things like Netscape
2433 form signing output easier to verify.
2436 *) Fix the ASN1 encoding of tags using the 'long form'.
2439 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
2440 STRING types. These convert content octets to and from the
2441 underlying type. The actual tag and length octets are
2442 already assumed to have been read in and checked. These
2443 are needed because all other string types have virtually
2444 identical handling apart from the tag. By having versions
2445 of the ASN1 functions that just operate on content octets
2446 IMPLICIT tagging can be handled properly. It also allows
2447 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
2448 and ASN1_INTEGER are identical apart from the tag.
2451 *) Change the handling of OID objects as follows:
2453 - New object identifiers are inserted in objects.txt, following
2454 the syntax given in objects.README.
2455 - objects.pl is used to process obj_mac.num and create a new
2457 - obj_dat.pl is used to create a new obj_dat.h, using the data in
2460 This is currently kind of a hack, and the perl code in objects.pl
2461 isn't very elegant, but it works as I intended. The simplest way
2462 to check that it worked correctly is to look in obj_dat.h and
2463 check the array nid_objs and make sure the objects haven't moved
2464 around (this is important!). Additions are OK, as well as
2465 consistent name changes.
2468 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
2471 *) Addition of the command line parameter '-rand file' to 'openssl req'.
2472 The given file adds to whatever has already been seeded into the
2473 random pool through the RANDFILE configuration file option or
2474 environment variable, or the default random state file.
2477 *) mkstack.pl now sorts each macro group into lexical order.
2478 Previously the output order depended on the order the files
2479 appeared in the directory, resulting in needless rewriting
2483 *) Patches to make OpenSSL compile under Win32 again. Mostly
2484 work arounds for the VC++ problem that it treats func() as
2485 func(void). Also stripped out the parts of mkdef.pl that
2486 added extra typesafe functions: these no longer exist.
2489 *) Reorganisation of the stack code. The macros are now all
2490 collected in safestack.h . Each macro is defined in terms of
2491 a "stack macro" of the form SKM_<name>(type, a, b). The
2492 DEBUG_SAFESTACK is now handled in terms of function casts,
2493 this has the advantage of retaining type safety without the
2494 use of additional functions. If DEBUG_SAFESTACK is not defined
2495 then the non typesafe macros are used instead. Also modified the
2496 mkstack.pl script to handle the new form. Needs testing to see
2497 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
2498 the default if no major problems. Similar behaviour for ASN1_SET_OF
2499 and PKCS12_STACK_OF.
2502 *) When some versions of IIS use the 'NET' form of private key the
2503 key derivation algorithm is different. Normally MD5(password) is
2504 used as a 128 bit RC4 key. In the modified case
2505 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
2506 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
2507 as the old Netscape_RSA functions except they have an additional
2508 'sgckey' parameter which uses the modified algorithm. Also added
2509 an -sgckey command line option to the rsa utility. Thanks to
2510 Adrian Peck <bertie@ncipher.com> for posting details of the modified
2511 algorithm to openssl-dev.
2514 *) The evp_local.h macros were using 'c.##kname' which resulted in
2515 invalid expansion on some systems (SCO 5.0.5 for example).
2516 Corrected to 'c.kname'.
2517 [Phillip Porch <root@theporch.com>]
2519 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
2520 a STACK of email addresses from a certificate or request, these look
2521 in the subject name and the subject alternative name extensions and
2522 omit any duplicate addresses.
2525 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
2526 This makes DSA verification about 2 % faster.
2529 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
2530 (meaning that now 2^5 values will be precomputed, which is only 4 KB
2531 plus overhead for 1024 bit moduli).
2532 This makes exponentiations about 0.5 % faster for 1024 bit
2533 exponents (as measured by "openssl speed rsa2048").
2536 *) Rename memory handling macros to avoid conflicts with other
2538 Malloc => OPENSSL_malloc
2539 Malloc_locked => OPENSSL_malloc_locked
2540 Realloc => OPENSSL_realloc
2541 Free => OPENSSL_free
2544 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
2545 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
2548 *) CygWin32 support.
2549 [John Jarvie <jjarvie@newsguy.com>]
2551 *) The type-safe stack code has been rejigged. It is now only compiled
2552 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
2553 by default all type-specific stack functions are "#define"d back to
2554 standard stack functions. This results in more streamlined output
2555 but retains the type-safety checking possibilities of the original
2559 *) The STACK code has been cleaned up, and certain type declarations
2560 that didn't make a lot of sense have been brought in line. This has
2561 also involved a cleanup of sorts in safestack.h to more correctly
2562 map type-safe stack functions onto their plain stack counterparts.
2563 This work has also resulted in a variety of "const"ifications of
2564 lots of the code, especially "_cmp" operations which should normally
2565 be prototyped with "const" parameters anyway.
2568 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
2569 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
2570 (The PRNG state consists of two parts, the large pool 'state' and 'md',
2571 where all of 'md' is used each time the PRNG is used, but 'state'
2572 is used only indexed by a cyclic counter. As entropy may not be
2573 well distributed from the beginning, 'md' is important as a
2574 chaining variable. However, the output function chains only half
2575 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
2576 all of 'md', and seeding with STATE_SIZE dummy bytes will result
2577 in all of 'state' being rewritten, with the new values depending
2578 on virtually all of 'md'. This overcomes the 80 bit limitation.)
2581 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
2582 the handshake is continued after ssl_verify_cert_chain();
2583 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
2584 can lead to 'unexplainable' connection aborts later.
2585 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
2587 *) Major EVP API cipher revision.
2588 Add hooks for extra EVP features. This allows various cipher
2589 parameters to be set in the EVP interface. Support added for variable
2590 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
2591 setting of RC2 and RC5 parameters.
2593 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
2596 Remove lots of duplicated code from the EVP library. For example *every*
2597 cipher init() function handles the 'iv' in the same way according to the
2598 cipher mode. They also all do nothing if the 'key' parameter is NULL and
2599 for CFB and OFB modes they zero ctx->num.
2601 New functionality allows removal of S/MIME code RC2 hack.
2603 Most of the routines have the same form and so can be declared in terms
2606 By shifting this to the top level EVP_CipherInit() it can be removed from
2607 all individual ciphers. If the cipher wants to handle IVs or keys
2608 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
2611 Change lots of functions like EVP_EncryptUpdate() to now return a
2612 value: although software versions of the algorithms cannot fail
2613 any installed hardware versions can.
2616 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
2617 this option is set, tolerate broken clients that send the negotiated
2618 protocol version number instead of the requested protocol version
2622 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
2623 i.e. non-zero for export ciphersuites, zero otherwise.
2624 Previous versions had this flag inverted, inconsistent with
2625 rsa_tmp_cb (..._TMP_RSA_CB).
2626 [Bodo Moeller; problem reported by Amit Chopra]
2628 *) Add missing DSA library text string. Work around for some IIS
2629 key files with invalid SEQUENCE encoding.
2632 *) Add a document (doc/standards.txt) that list all kinds of standards
2633 and so on that are implemented in OpenSSL.
2636 *) Enhance c_rehash script. Old version would mishandle certificates
2637 with the same subject name hash and wouldn't handle CRLs at all.
2638 Added -fingerprint option to crl utility, to support new c_rehash
2642 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
2645 *) Fix for SSL server purpose checking. Server checking was
2646 rejecting certificates which had extended key usage present
2647 but no ssl client purpose.
2648 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
2650 *) Make PKCS#12 code work with no password. The PKCS#12 spec
2651 is a little unclear about how a blank password is handled.
2652 Since the password in encoded as a BMPString with terminating
2653 double NULL a zero length password would end up as just the
2654 double NULL. However no password at all is different and is
2655 handled differently in the PKCS#12 key generation code. NS
2656 treats a blank password as zero length. MSIE treats it as no
2657 password on export: but it will try both on import. We now do
2658 the same: PKCS12_parse() tries zero length and no password if
2659 the password is set to "" or NULL (NULL is now a valid password:
2660 it wasn't before) as does the pkcs12 application.
2663 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
2664 perror when PEM_read_bio_X509_REQ fails, the error message must
2665 be obtained from the error queue.
2668 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
2669 it in ERR_remove_state if appropriate, and change ERR_get_state
2670 accordingly to avoid race conditions (this is necessary because
2671 thread_hash is no longer constant once set).
2674 *) Bugfix for linux-elf makefile.one.
2677 *) RSA_get_default_method() will now cause a default
2678 RSA_METHOD to be chosen if one doesn't exist already.
2679 Previously this was only set during a call to RSA_new()
2680 or RSA_new_method(NULL) meaning it was possible for
2681 RSA_get_default_method() to return NULL.
2684 *) Added native name translation to the existing DSO code
2685 that will convert (if the flag to do so is set) filenames
2686 that are sufficiently small and have no path information
2687 into a canonical native form. Eg. "blah" converted to
2688 "libblah.so" or "blah.dll" etc.
2691 *) New function ERR_error_string_n(e, buf, len) which is like
2692 ERR_error_string(e, buf), but writes at most 'len' bytes
2693 including the 0 terminator. For ERR_error_string_n, 'buf'
2695 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
2697 *) CONF library reworked to become more general. A new CONF
2698 configuration file reader "class" is implemented as well as a
2699 new functions (NCONF_*, for "New CONF") to handle it. The now
2700 old CONF_* functions are still there, but are reimplemented to
2701 work in terms of the new functions. Also, a set of functions
2702 to handle the internal storage of the configuration data is
2703 provided to make it easier to write new configuration file
2704 reader "classes" (I can definitely see something reading a
2705 configuration file in XML format, for example), called _CONF_*,
2706 or "the configuration storage API"...
2708 The new configuration file reading functions are:
2710 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
2711 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
2713 NCONF_default, NCONF_WIN32
2715 NCONF_dump_fp, NCONF_dump_bio
2717 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
2718 NCONF_new creates a new CONF object. This works in the same way
2719 as other interfaces in OpenSSL, like the BIO interface.
2720 NCONF_dump_* dump the internal storage of the configuration file,
2721 which is useful for debugging. All other functions take the same
2722 arguments as the old CONF_* functions wth the exception of the
2723 first that must be a `CONF *' instead of a `LHASH *'.
2725 To make it easer to use the new classes with the old CONF_* functions,
2726 the function CONF_set_default_method is provided.
2729 *) Add '-tls1' option to 'openssl ciphers', which was already
2730 mentioned in the documentation but had not been implemented.
2731 (This option is not yet really useful because even the additional
2732 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
2735 *) Initial DSO code added into libcrypto for letting OpenSSL (and
2736 OpenSSL-based applications) load shared libraries and bind to
2737 them in a portable way.
2738 [Geoff Thorpe, with contributions from Richard Levitte]
2740 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
2742 *) Make sure _lrotl and _lrotr are only used with MSVC.
2744 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
2745 (the default implementation of RAND_status).
2747 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
2748 to '-clrext' (= clear extensions), as intended and documented.
2749 [Bodo Moeller; inconsistency pointed out by Michael Attili
2752 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
2753 was larger than the MD block size.
2754 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
2756 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
2757 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
2758 using the passed key: if the passed key was a private key the result
2759 of X509_print(), for example, would be to print out all the private key
2763 *) des_quad_cksum() byte order bug fix.
2764 [Ulf Möller, using the problem description in krb4-0.9.7, where
2765 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
2767 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
2769 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
2771 *) For easily testing in shell scripts whether some command
2772 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
2773 returns with exit code 0 iff no command of the given name is available.
2774 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
2775 the output goes to stdout and nothing is printed to stderr.
2776 Additional arguments are always ignored.
2778 Since for each cipher there is a command of the same name,
2779 the 'no-cipher' compilation switches can be tested this way.
2781 ('openssl no-XXX' is not able to detect pseudo-commands such
2782 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
2785 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
2788 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
2789 is set; it will be thrown away anyway because each handshake creates
2791 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
2792 to parameters -- in previous versions (since OpenSSL 0.9.3) the
2793 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
2794 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
2797 *) New s_client option -ign_eof: EOF at stdin is ignored, and
2798 'Q' and 'R' lose their special meanings (quit/renegotiate).
2799 This is part of what -quiet does; unlike -quiet, -ign_eof
2800 does not suppress any output.
2803 *) Add compatibility options to the purpose and trust code. The
2804 purpose X509_PURPOSE_ANY is "any purpose" which automatically
2805 accepts a certificate or CA, this was the previous behaviour,
2806 with all the associated security issues.
2808 X509_TRUST_COMPAT is the old trust behaviour: only and
2809 automatically trust self signed roots in certificate store. A
2810 new trust setting X509_TRUST_DEFAULT is used to specify that
2811 a purpose has no associated trust setting and it should instead
2812 use the value in the default purpose.
2815 *) Fix the PKCS#8 DSA private key code so it decodes keys again
2816 and fix a memory leak.
2819 *) In util/mkerr.pl (which implements 'make errors'), preserve
2820 reason strings from the previous version of the .c file, as
2821 the default to have only downcase letters (and digits) in
2822 automatically generated reasons codes is not always appropriate.
2825 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
2826 using strerror. Previously, ERR_reason_error_string() returned
2827 library names as reason strings for SYSerr; but SYSerr is a special
2828 case where small numbers are errno values, not library numbers.
2831 *) Add '-dsaparam' option to 'openssl dhparam' application. This
2832 converts DSA parameters into DH parameters. (When creating parameters,
2833 DSA_generate_parameters is used.)
2836 *) Include 'length' (recommended exponent length) in C code generated
2837 by 'openssl dhparam -C'.
2840 *) The second argument to set_label in perlasm was already being used
2841 so couldn't be used as a "file scope" flag. Moved to third argument
2845 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
2846 instead of RAND_bytes for encryption IVs and salts.
2849 *) Include RAND_status() into RAND_METHOD instead of implementing
2850 it only for md_rand.c Otherwise replacing the PRNG by calling
2851 RAND_set_rand_method would be impossible.
2854 *) Don't let DSA_generate_key() enter an infinite loop if the random
2855 number generation fails.
2858 *) New 'rand' application for creating pseudo-random output.
2861 *) Added configuration support for Linux/IA64
2862 [Rolf Haberrecker <rolf@suse.de>]
2864 *) Assembler module support for Mingw32.
2867 *) Shared library support for HPUX (in shlib/).
2868 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
2870 *) Shared library support for Solaris gcc.
2871 [Lutz Behnke <behnke@trustcenter.de>]
2873 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
2875 *) PKCS7_encrypt() was adding text MIME headers twice because they
2876 were added manually and by SMIME_crlf_copy().
2879 *) In bntest.c don't call BN_rand with zero bits argument.
2880 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
2882 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
2883 case was implemented. This caused BN_div_recp() to fail occasionally.
2886 *) Add an optional second argument to the set_label() in the perl
2887 assembly language builder. If this argument exists and is set
2888 to 1 it signals that the assembler should use a symbol whose
2889 scope is the entire file, not just the current function. This
2890 is needed with MASM which uses the format label:: for this scope.
2891 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
2893 *) Change the ASN1 types so they are typedefs by default. Before
2894 almost all types were #define'd to ASN1_STRING which was causing
2895 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
2899 *) Change names of new functions to the new get1/get0 naming
2900 convention: After 'get1', the caller owns a reference count
2901 and has to call ..._free; 'get0' returns a pointer to some
2902 data structure without incrementing reference counters.
2903 (Some of the existing 'get' functions increment a reference
2904 counter, some don't.)
2905 Similarly, 'set1' and 'add1' functions increase reference
2906 counters or duplicate objects.
2909 *) Allow for the possibility of temp RSA key generation failure:
2910 the code used to assume it always worked and crashed on failure.
2913 *) Fix potential buffer overrun problem in BIO_printf().
2914 [Ulf Möller, using public domain code by Patrick Powell; problem
2915 pointed out by David Sacerdote <das33@cornell.edu>]
2917 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
2918 RAND_egd() and RAND_status(). In the command line application,
2919 the EGD socket can be specified like a seed file using RANDFILE
2923 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
2924 Some CAs (e.g. Verisign) distribute certificates in this form.
2927 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
2928 list to exclude them. This means that no special compilation option
2929 is needed to use anonymous DH: it just needs to be included in the
2933 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
2934 EVP_MD_type. The old functionality is available in a new macro called
2935 EVP_MD_md(). Change code that uses it and update docs.
2938 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
2939 where the 'void *' argument is replaced by a function pointer argument.
2940 Previously 'void *' was abused to point to functions, which works on
2941 many platforms, but is not correct. As these functions are usually
2942 called by macros defined in OpenSSL header files, most source code
2943 should work without changes.
2946 *) <openssl/opensslconf.h> (which is created by Configure) now contains
2947 sections with information on -D... compiler switches used for
2948 compiling the library so that applications can see them. To enable
2949 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
2950 must be defined. E.g.,
2951 #define OPENSSL_ALGORITHM_DEFINES
2952 #include <openssl/opensslconf.h>
2953 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
2954 [Richard Levitte, Ulf and Bodo Möller]
2956 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
2960 *) Change the 'other' type in certificate aux info to a STACK_OF
2961 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
2962 the required ASN1 format: arbitrary types determined by an OID.
2965 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
2966 argument to 'req'. This is not because the function is newer or
2967 better than others it just uses the work 'NEW' in the certificate
2968 request header lines. Some software needs this.
2971 *) Reorganise password command line arguments: now passwords can be
2972 obtained from various sources. Delete the PEM_cb function and make
2973 it the default behaviour: i.e. if the callback is NULL and the
2974 usrdata argument is not NULL interpret it as a null terminated pass
2975 phrase. If usrdata and the callback are NULL then the pass phrase
2976 is prompted for as usual.
2979 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
2980 the support is automatically enabled. The resulting binaries will
2981 autodetect the card and use it if present.
2982 [Ben Laurie and Compaq Inc.]
2984 *) Work around for Netscape hang bug. This sends certificate request
2985 and server done in one record. Since this is perfectly legal in the
2986 SSL/TLS protocol it isn't a "bug" option and is on by default. See
2987 the bugs/SSLv3 entry for more info.
2990 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
2993 *) Add -rand argument to smime and pkcs12 applications and read/write
2997 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
3000 *) Add command line password options to the remaining applications.
3003 *) Bug fix for BN_div_recp() for numerators with an even number of
3007 *) More tests in bntest.c, and changed test_bn output.
3010 *) ./config recognizes MacOS X now.
3013 *) Bug fix for BN_div() when the first words of num and divsor are
3014 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
3017 *) Add support for various broken PKCS#8 formats, and command line
3018 options to produce them.
3021 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
3022 get temporary BIGNUMs from a BN_CTX.
3025 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
3029 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
3030 include a #define from the old name to the new. The original intent
3031 was that statically linked binaries could for example just call
3032 SSLeay_add_all_ciphers() to just add ciphers to the table and not
3033 link with digests. This never worked becayse SSLeay_add_all_digests()
3034 and SSLeay_add_all_ciphers() were in the same source file so calling
3035 one would link with the other. They are now in separate source files.
3038 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
3041 *) Use a less unusual form of the Miller-Rabin primality test (it used
3042 a binary algorithm for exponentiation integrated into the Miller-Rabin
3043 loop, our standard modexp algorithms are faster).
3046 *) Support for the EBCDIC character set completed.
3047 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
3049 *) Source code cleanups: use const where appropriate, eliminate casts,
3050 use void * instead of char * in lhash.
3053 *) Bugfix: ssl3_send_server_key_exchange was not restartable
3054 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
3055 this the server could overwrite ephemeral keys that the client
3059 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
3060 using 50 iterations of the Rabin-Miller test.
3062 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
3063 iterations of the Rabin-Miller test as required by the appendix
3064 to FIPS PUB 186[-1]) instead of DSA_is_prime.
3065 As BN_is_prime_fasttest includes trial division, DSA parameter
3066 generation becomes much faster.
3068 This implies a change for the callback functions in DSA_is_prime
3069 and DSA_generate_parameters: The callback function is called once
3070 for each positive witness in the Rabin-Miller test, not just
3071 occasionally in the inner loop; and the parameters to the
3072 callback function now provide an iteration count for the outer
3073 loop rather than for the current invocation of the inner loop.
3074 DSA_generate_parameters additionally can call the callback
3075 function with an 'iteration count' of -1, meaning that a
3076 candidate has passed the trial division test (when q is generated
3077 from an application-provided seed, trial division is skipped).
3080 *) New function BN_is_prime_fasttest that optionally does trial
3081 division before starting the Rabin-Miller test and has
3082 an additional BN_CTX * argument (whereas BN_is_prime always
3083 has to allocate at least one BN_CTX).
3084 'callback(1, -1, cb_arg)' is called when a number has passed the
3085 trial division stage.
3088 *) Fix for bug in CRL encoding. The validity dates weren't being handled
3092 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
3095 *) New function BN_pseudo_rand().
3098 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
3099 bignum version of BN_from_montgomery() with the working code from
3100 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
3104 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
3105 made it impossible to use the same SSL_SESSION data structure in
3106 SSL2 clients in multiple threads.
3109 *) The return value of RAND_load_file() no longer counts bytes obtained
3110 by stat(). RAND_load_file(..., -1) is new and uses the complete file
3111 to seed the PRNG (previously an explicit byte count was required).
3112 [Ulf Möller, Bodo Möller]
3114 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
3115 used (char *) instead of (void *) and had casts all over the place.
3118 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
3121 *) Retain source code compatibility for BN_prime_checks macro:
3122 BN_is_prime(..., BN_prime_checks, ...) now uses
3123 BN_prime_checks_for_size to determine the appropriate number of
3124 Rabin-Miller iterations.
3127 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
3128 DH_CHECK_P_NOT_SAFE_PRIME.
3129 (Check if this is true? OpenPGP calls them "strong".)
3132 *) Merge the functionality of "dh" and "gendh" programs into a new program
3133 "dhparam". The old programs are retained for now but will handle DH keys
3134 (instead of parameters) in future.
3137 *) Make the ciphers, s_server and s_client programs check the return values
3138 when a new cipher list is set.
3141 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
3142 ciphers. Before when the 56bit ciphers were enabled the sorting was
3145 The syntax for the cipher sorting has been extended to support sorting by
3146 cipher-strength (using the strength_bits hard coded in the tables).
3147 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
3149 Fix a bug in the cipher-command parser: when supplying a cipher command
3150 string with an "undefined" symbol (neither command nor alphanumeric
3151 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
3152 an error is flagged.
3154 Due to the strength-sorting extension, the code of the
3155 ssl_create_cipher_list() function was completely rearranged. I hope that
3156 the readability was also increased :-)
3157 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
3159 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
3160 for the first serial number and places 2 in the serial number file. This
3161 avoids problems when the root CA is created with serial number zero and
3162 the first user certificate has the same issuer name and serial number
3166 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
3167 the new code. Add documentation for this stuff.
3170 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
3171 X509_*() to X509at_*() on the grounds that they don't handle X509
3172 structures and behave in an analagous way to the X509v3 functions:
3173 they shouldn't be called directly but wrapper functions should be used
3176 So we also now have some wrapper functions that call the X509at functions
3177 when passed certificate requests. (TO DO: similar things can be done with
3178 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
3179 things. Some of these need some d2i or i2d and print functionality
3180 because they handle more complex structures.)
3183 *) Add missing #ifndefs that caused missing symbols when building libssl
3184 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
3185 NO_RSA in ssl/s2*.c.
3186 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
3188 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
3189 has a return value which indicates the quality of the random data
3190 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
3191 error queue. New function RAND_pseudo_bytes() generates output that is
3192 guaranteed to be unique but not unpredictable. RAND_add is like
3193 RAND_seed, but takes an extra argument for an entropy estimate
3194 (RAND_seed always assumes full entropy).
3197 *) Do more iterations of Rabin-Miller probable prime test (specifically,
3198 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
3199 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
3200 in crypto/bn/bn_prime.c for the complete table). This guarantees a
3201 false-positive rate of at most 2^-80 for random input.
3204 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
3207 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
3208 in the 0.9.5 release), this returns the chain
3209 from an X509_CTX structure with a dup of the stack and all
3210 the X509 reference counts upped: so the stack will exist
3211 after X509_CTX_cleanup() has been called. Modify pkcs12.c
3214 Also make SSL_SESSION_print() print out the verify return
3218 *) Add manpage for the pkcs12 command. Also change the default
3219 behaviour so MAC iteration counts are used unless the new
3220 -nomaciter option is used. This improves file security and
3221 only older versions of MSIE (4.0 for example) need it.
3224 *) Honor the no-xxx Configure options when creating .DEF files.
3227 *) Add PKCS#10 attributes to field table: challengePassword,
3228 unstructuredName and unstructuredAddress. These are taken from
3229 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
3230 international characters are used.
3232 More changes to X509_ATTRIBUTE code: allow the setting of types
3233 based on strings. Remove the 'loc' parameter when adding
3234 attributes because these will be a SET OF encoding which is sorted
3238 *) Initial changes to the 'req' utility to allow request generation
3239 automation. This will allow an application to just generate a template
3240 file containing all the field values and have req construct the
3243 Initial support for X509_ATTRIBUTE handling. Stacks of these are
3244 used all over the place including certificate requests and PKCS#7
3245 structures. They are currently handled manually where necessary with
3246 some primitive wrappers for PKCS#7. The new functions behave in a
3247 manner analogous to the X509 extension functions: they allow
3248 attributes to be looked up by NID and added.
3250 Later something similar to the X509V3 code would be desirable to
3251 automatically handle the encoding, decoding and printing of the
3252 more complex types. The string types like challengePassword can
3253 be handled by the string table functions.
3255 Also modified the multi byte string table handling. Now there is
3256 a 'global mask' which masks out certain types. The table itself
3257 can use the flag STABLE_NO_MASK to ignore the mask setting: this
3258 is useful when for example there is only one permissible type
3259 (as in countryName) and using the mask might result in no valid
3263 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
3264 SSL_get_peer_finished to allow applications to obtain the latest
3265 Finished messages sent to the peer or expected from the peer,
3266 respectively. (SSL_get_peer_finished is usually the Finished message
3267 actually received from the peer, otherwise the protocol will be aborted.)
3269 As the Finished message are message digests of the complete handshake
3270 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
3271 be used for external authentication procedures when the authentication
3272 provided by SSL/TLS is not desired or is not enough.
3275 *) Enhanced support for Alpha Linux is added. Now ./config checks if
3276 the host supports BWX extension and if Compaq C is present on the
3277 $PATH. Just exploiting of the BWX extension results in 20-30%
3278 performance kick for some algorithms, e.g. DES and RC4 to mention
3279 a couple. Compaq C in turn generates ~20% faster code for MD5 and
3283 *) Add support for MS "fast SGC". This is arguably a violation of the
3284 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
3285 weak crypto and after checking the certificate is SGC a second one
3286 with strong crypto. MS SGC stops the first handshake after receiving
3287 the server certificate message and sends a second client hello. Since
3288 a server will typically do all the time consuming operations before
3289 expecting any further messages from the client (server key exchange
3290 is the most expensive) there is little difference between the two.
3292 To get OpenSSL to support MS SGC we have to permit a second client
3293 hello message after we have sent server done. In addition we have to
3294 reset the MAC if we do get this second client hello.
3297 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
3298 if a DER encoded private key is RSA or DSA traditional format. Changed
3299 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
3300 format DER encoded private key. Newer code should use PKCS#8 format which
3301 has the key type encoded in the ASN1 structure. Added DER private key
3302 support to pkcs8 application.
3305 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
3306 ciphersuites has been selected (as required by the SSL 3/TLS 1
3307 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
3308 is set, we interpret this as a request to violate the specification
3309 (the worst that can happen is a handshake failure, and 'correct'
3310 behaviour would result in a handshake failure anyway).
3313 *) In SSL_CTX_add_session, take into account that there might be multiple
3314 SSL_SESSION structures with the same session ID (e.g. when two threads
3315 concurrently obtain them from an external cache).
3316 The internal cache can handle only one SSL_SESSION with a given ID,
3317 so if there's a conflict, we now throw out the old one to achieve
3321 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
3322 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
3323 some routines that use cipher OIDs: some ciphers do not have OIDs
3324 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
3328 *) Simplify the trust setting structure and code. Now we just have
3329 two sequences of OIDs for trusted and rejected settings. These will
3330 typically have values the same as the extended key usage extension
3331 and any application specific purposes.
3333 The trust checking code now has a default behaviour: it will just
3334 check for an object with the same NID as the passed id. Functions can
3335 be provided to override either the default behaviour or the behaviour
3336 for a given id. SSL client, server and email already have functions
3337 in place for compatibility: they check the NID and also return "trusted"
3338 if the certificate is self signed.
3341 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
3342 traditional format into an EVP_PKEY structure.
3345 *) Add a password callback function PEM_cb() which either prompts for
3346 a password if usr_data is NULL or otherwise assumes it is a null
3347 terminated password. Allow passwords to be passed on command line
3348 environment or config files in a few more utilities.
3351 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
3352 keys. Add some short names for PKCS#8 PBE algorithms and allow them
3353 to be specified on the command line for the pkcs8 and pkcs12 utilities.
3354 Update documentation.
3357 *) Support for ASN1 "NULL" type. This could be handled before by using
3358 ASN1_TYPE but there wasn't any function that would try to read a NULL
3359 and produce an error if it couldn't. For compatibility we also have
3360 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
3361 don't allocate anything because they don't need to.
3364 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
3366 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
3368 *) Rebuild of the memory allocation routines used by OpenSSL code and
3369 possibly others as well. The purpose is to make an interface that
3370 provide hooks so anyone can build a separate set of allocation and
3371 deallocation routines to be used by OpenSSL, for example memory
3372 pool implementations, or something else, which was previously hard
3373 since Malloc(), Realloc() and Free() were defined as macros having
3374 the values malloc, realloc and free, respectively (except for Win32
3375 compilations). The same is provided for memory debugging code.
3376 OpenSSL already comes with functionality to find memory leaks, but
3377 this gives people a chance to debug other memory problems.
3379 With these changes, a new set of functions and macros have appeared:
3381 CRYPTO_set_mem_debug_functions() [F]
3382 CRYPTO_get_mem_debug_functions() [F]
3383 CRYPTO_dbg_set_options() [F]
3384 CRYPTO_dbg_get_options() [F]
3385 CRYPTO_malloc_debug_init() [M]
3387 The memory debug functions are NULL by default, unless the library
3388 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
3389 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
3390 gives the standard debugging functions that come with OpenSSL) or
3391 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
3392 provided by the library user) must be used. When the standard
3393 debugging functions are used, CRYPTO_dbg_set_options can be used to
3394 request additional information:
3395 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
3396 the CRYPTO_MDEBUG_xxx macro when compiling the library.
3398 Also, things like CRYPTO_set_mem_functions will always give the
3399 expected result (the new set of functions is used for allocation
3400 and deallocation) at all times, regardless of platform and compiler
3403 To finish it up, some functions that were never use in any other
3404 way than through macros have a new API and new semantic:
3407 CRYPTO_dbg_realloc()
3410 All macros of value have retained their old syntax.
3411 [Richard Levitte and Bodo Moeller]
3413 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
3414 ordering of SMIMECapabilities wasn't in "strength order" and there
3415 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
3419 *) Some ASN1 types with illegal zero length encoding (INTEGER,
3420 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
3421 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
3423 *) Merge in my S/MIME library for OpenSSL. This provides a simple
3424 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
3425 functionality to handle multipart/signed properly) and a utility
3426 called 'smime' to call all this stuff. This is based on code I
3427 originally wrote for Celo who have kindly allowed it to be
3428 included in OpenSSL.
3431 *) Add variants des_set_key_checked and des_set_key_unchecked of
3432 des_set_key (aka des_key_sched). Global variable des_check_key
3433 decides which of these is called by des_set_key; this way
3434 des_check_key behaves as it always did, but applications and
3435 the library itself, which was buggy for des_check_key == 1,
3436 have a cleaner way to pick the version they need.
3439 *) New function PKCS12_newpass() which changes the password of a
3443 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
3444 dynamic mix. In both cases the ids can be used as an index into the
3445 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
3446 functions so they accept a list of the field values and the
3447 application doesn't need to directly manipulate the X509_TRUST
3451 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
3455 *) Modify the way the V3 extension code looks up extensions. This now
3456 works in a similar way to the object code: we have some "standard"
3457 extensions in a static table which is searched with OBJ_bsearch()
3458 and the application can add dynamic ones if needed. The file
3459 crypto/x509v3/ext_dat.h now has the info: this file needs to be
3460 updated whenever a new extension is added to the core code and kept
3461 in ext_nid order. There is a simple program 'tabtest.c' which checks
3462 this. New extensions are not added too often so this file can readily
3463 be maintained manually.
3465 There are two big advantages in doing things this way. The extensions
3466 can be looked up immediately and no longer need to be "added" using
3467 X509V3_add_standard_extensions(): this function now does nothing.
3468 [Side note: I get *lots* of email saying the extension code doesn't
3469 work because people forget to call this function]
3470 Also no dynamic allocation is done unless new extensions are added:
3471 so if we don't add custom extensions there is no need to call
3472 X509V3_EXT_cleanup().
3475 *) Modify enc utility's salting as follows: make salting the default. Add a
3476 magic header, so unsalted files fail gracefully instead of just decrypting
3477 to garbage. This is because not salting is a big security hole, so people
3478 should be discouraged from doing it.
3481 *) Fixes and enhancements to the 'x509' utility. It allowed a message
3482 digest to be passed on the command line but it only used this
3483 parameter when signing a certificate. Modified so all relevant
3484 operations are affected by the digest parameter including the
3485 -fingerprint and -x509toreq options. Also -x509toreq choked if a
3486 DSA key was used because it didn't fix the digest.
3489 *) Initial certificate chain verify code. Currently tests the untrusted
3490 certificates for consistency with the verify purpose (which is set
3491 when the X509_STORE_CTX structure is set up) and checks the pathlength.
3493 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
3494 this is because it will reject chains with invalid extensions whereas
3495 every previous version of OpenSSL and SSLeay made no checks at all.
3497 Trust code: checks the root CA for the relevant trust settings. Trust
3498 settings have an initial value consistent with the verify purpose: e.g.
3499 if the verify purpose is for SSL client use it expects the CA to be
3500 trusted for SSL client use. However the default value can be changed to
3501 permit custom trust settings: one example of this would be to only trust
3502 certificates from a specific "secure" set of CAs.
3504 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
3505 which should be used for version portability: especially since the
3506 verify structure is likely to change more often now.
3508 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
3509 to set them. If not set then assume SSL clients will verify SSL servers
3512 Two new options to the verify program: -untrusted allows a set of
3513 untrusted certificates to be passed in and -purpose which sets the
3514 intended purpose of the certificate. If a purpose is set then the
3515 new chain verify code is used to check extension consistency.
3518 *) Support for the authority information access extension.
3521 *) Modify RSA and DSA PEM read routines to transparently handle
3522 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
3523 public keys in a format compatible with certificate
3524 SubjectPublicKeyInfo structures. Unfortunately there were already
3525 functions called *_PublicKey_* which used various odd formats so
3526 these are retained for compatibility: however the DSA variants were
3527 never in a public release so they have been deleted. Changed dsa/rsa
3528 utilities to handle the new format: note no releases ever handled public
3529 keys so we should be OK.
3531 The primary motivation for this change is to avoid the same fiasco
3532 that dogs private keys: there are several incompatible private key
3533 formats some of which are standard and some OpenSSL specific and
3534 require various evil hacks to allow partial transparent handling and
3535 even then it doesn't work with DER formats. Given the option anything
3536 other than PKCS#8 should be dumped: but the other formats have to
3537 stay in the name of compatibility.
3539 With public keys and the benefit of hindsight one standard format
3540 is used which works with EVP_PKEY, RSA or DSA structures: though
3541 it clearly returns an error if you try to read the wrong kind of key.
3543 Added a -pubkey option to the 'x509' utility to output the public key.
3544 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
3545 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
3546 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
3547 that do the same as the EVP_PKEY_assign_*() except they up the
3548 reference count of the added key (they don't "swallow" the
3552 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
3553 CRLs would fail if the file contained no certificates or no CRLs:
3554 added a new function to read in both types and return the number
3555 read: this means that if none are read it will be an error. The
3556 DER versions of the certificate and CRL reader would always fail
3557 because it isn't possible to mix certificates and CRLs in DER format
3558 without choking one or the other routine. Changed this to just read
3559 a certificate: this is the best we can do. Also modified the code
3560 in apps/verify.c to take notice of return codes: it was previously
3561 attempting to read in certificates from NULL pointers and ignoring
3562 any errors: this is one reason why the cert and CRL reader seemed
3563 to work. It doesn't check return codes from the default certificate
3564 routines: these may well fail if the certificates aren't installed.
3567 *) Code to support otherName option in GeneralName.
3570 *) First update to verify code. Change the verify utility
3571 so it warns if it is passed a self signed certificate:
3572 for consistency with the normal behaviour. X509_verify
3573 has been modified to it will now verify a self signed
3574 certificate if *exactly* the same certificate appears
3575 in the store: it was previously impossible to trust a
3576 single self signed certificate. This means that:
3577 openssl verify ss.pem
3578 now gives a warning about a self signed certificate but
3579 openssl verify -CAfile ss.pem ss.pem
3583 *) For servers, store verify_result in SSL_SESSION data structure
3584 (and add it to external session representation).
3585 This is needed when client certificate verifications fails,
3586 but an application-provided verification callback (set by
3587 SSL_CTX_set_cert_verify_callback) allows accepting the session
3588 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
3589 but returns 1): When the session is reused, we have to set
3590 ssl->verify_result to the appropriate error code to avoid
3592 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
3594 *) Fix a bug in the new PKCS#7 code: it didn't consider the
3595 case in PKCS7_dataInit() where the signed PKCS7 structure
3596 didn't contain any existing data because it was being created.
3597 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
3599 *) Add a salt to the key derivation routines in enc.c. This
3600 forms the first 8 bytes of the encrypted file. Also add a
3601 -S option to allow a salt to be input on the command line.
3604 *) New function X509_cmp(). Oddly enough there wasn't a function
3605 to compare two certificates. We do this by working out the SHA1
3606 hash and comparing that. X509_cmp() will be needed by the trust
3610 *) SSL_get1_session() is like SSL_get_session(), but increments
3611 the reference count in the SSL_SESSION returned.
3612 [Geoff Thorpe <geoff@eu.c2.net>]
3614 *) Fix for 'req': it was adding a null to request attributes.
3615 Also change the X509_LOOKUP and X509_INFO code to handle
3616 certificate auxiliary information.
3619 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
3623 *) Add the possibility to add extra information to the memory leak
3624 detecting output, to form tracebacks, showing from where each
3625 allocation was originated: CRYPTO_push_info("constant string") adds
3626 the string plus current file name and line number to a per-thread
3627 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
3628 is like calling CYRPTO_pop_info() until the stack is empty.
3629 Also updated memory leak detection code to be multi-thread-safe.
3632 *) Add options -text and -noout to pkcs7 utility and delete the
3633 encryption options which never did anything. Update docs.
3636 *) Add options to some of the utilities to allow the pass phrase
3637 to be included on either the command line (not recommended on
3638 OSes like Unix) or read from the environment. Update the
3639 manpages and fix a few bugs.
3642 *) Add a few manpages for some of the openssl commands.
3645 *) Fix the -revoke option in ca. It was freeing up memory twice,
3646 leaking and not finding already revoked certificates.
3649 *) Extensive changes to support certificate auxiliary information.
3650 This involves the use of X509_CERT_AUX structure and X509_AUX
3651 functions. An X509_AUX function such as PEM_read_X509_AUX()
3652 can still read in a certificate file in the usual way but it
3653 will also read in any additional "auxiliary information". By
3654 doing things this way a fair degree of compatibility can be
3655 retained: existing certificates can have this information added
3656 using the new 'x509' options.
3658 Current auxiliary information includes an "alias" and some trust
3659 settings. The trust settings will ultimately be used in enhanced
3660 certificate chain verification routines: currently a certificate
3661 can only be trusted if it is self signed and then it is trusted
3665 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
3666 The problem was that one of the replacement routines had not been working
3667 since SSLeay releases. For now the offending routine has been replaced
3668 with non-optimised assembler. Even so, this now gives around 95%
3669 performance improvement for 1024 bit RSA signs.
3672 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
3673 handling. Most clients have the effective key size in bits equal to
3674 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
3675 A few however don't do this and instead use the size of the decrypted key
3676 to determine the RC2 key length and the AlgorithmIdentifier to determine
3677 the effective key length. In this case the effective key length can still
3678 be 40 bits but the key length can be 168 bits for example. This is fixed
3679 by manually forcing an RC2 key into the EVP_PKEY structure because the
3680 EVP code can't currently handle unusual RC2 key sizes: it always assumes
3681 the key length and effective key length are equal.
3684 *) Add a bunch of functions that should simplify the creation of
3685 X509_NAME structures. Now you should be able to do:
3686 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
3687 and have it automatically work out the correct field type and fill in
3688 the structures. The more adventurous can try:
3689 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
3690 and it will (hopefully) work out the correct multibyte encoding.
3693 *) Change the 'req' utility to use the new field handling and multibyte
3694 copy routines. Before the DN field creation was handled in an ad hoc
3695 way in req, ca, and x509 which was rather broken and didn't support
3696 BMPStrings or UTF8Strings. Since some software doesn't implement
3697 BMPStrings or UTF8Strings yet, they can be enabled using the config file
3698 using the dirstring_type option. See the new comment in the default
3699 openssl.cnf for more info.
3702 *) Make crypto/rand/md_rand.c more robust:
3703 - Assure unique random numbers after fork().
3704 - Make sure that concurrent threads access the global counter and
3705 md serializably so that we never lose entropy in them
3706 or use exactly the same state in multiple threads.
3707 Access to the large state is not always serializable because
3708 the additional locking could be a performance killer, and
3709 md should be large enough anyway.
3712 *) New file apps/app_rand.c with commonly needed functionality
3713 for handling the random seed file.
3715 Use the random seed file in some applications that previously did not:
3717 dsaparam -genkey (which also ignored its '-rand' option),
3720 x509 (when signing).
3721 Except on systems with /dev/urandom, it is crucial to have a random
3722 seed file at least for key creation, DSA signing, and for DH exchanges;
3723 for RSA signatures we could do without one.
3725 gendh and gendsa (unlike genrsa) used to read only the first byte
3726 of each file listed in the '-rand' option. The function as previously
3727 found in genrsa is now in app_rand.c and is used by all programs
3728 that support '-rand'.
3731 *) In RAND_write_file, use mode 0600 for creating files;
3732 don't just chmod when it may be too late.
3735 *) Report an error from X509_STORE_load_locations
3736 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
3739 *) New function ASN1_mbstring_copy() this copies a string in either
3740 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
3741 into an ASN1_STRING type. A mask of permissible types is passed
3742 and it chooses the "minimal" type to use or an error if not type
3746 *) Add function equivalents to the various macros in asn1.h. The old
3747 macros are retained with an M_ prefix. Code inside the library can
3748 use the M_ macros. External code (including the openssl utility)
3749 should *NOT* in order to be "shared library friendly".
3752 *) Add various functions that can check a certificate's extensions
3753 to see if it usable for various purposes such as SSL client,
3754 server or S/MIME and CAs of these types. This is currently
3755 VERY EXPERIMENTAL but will ultimately be used for certificate chain
3756 verification. Also added a -purpose flag to x509 utility to
3757 print out all the purposes.
3760 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
3764 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
3765 for, obtain and decode and extension and obtain its critical flag.
3766 This allows all the necessary extension code to be handled in a
3767 single function call.
3770 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
3771 platforms. See crypto/rc4/rc4_enc.c for further details.
3774 *) New -noout option to asn1parse. This causes no output to be produced
3775 its main use is when combined with -strparse and -out to extract data
3776 from a file (which may not be in ASN.1 format).
3779 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
3780 when producing the local key id.
3781 [Richard Levitte <levitte@stacken.kth.se>]
3783 *) New option -dhparam in s_server. This allows a DH parameter file to be
3784 stated explicitly. If it is not stated then it tries the first server
3785 certificate file. The previous behaviour hard coded the filename
3789 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
3790 a public key to be input or output. For example:
3791 openssl rsa -in key.pem -pubout -out pubkey.pem
3792 Also added necessary DSA public key functions to handle this.
3795 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
3796 in the message. This was handled by allowing
3797 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
3798 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
3800 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
3801 to the end of the strings whereas this didn't. This would cause problems
3802 if strings read with d2i_ASN1_bytes() were later modified.
3803 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
3805 *) Fix for base64 decode bug. When a base64 bio reads only one line of
3806 data and it contains EOF it will end up returning an error. This is
3807 caused by input 46 bytes long. The cause is due to the way base64
3808 BIOs find the start of base64 encoded data. They do this by trying a
3809 trial decode on each line until they find one that works. When they
3810 do a flag is set and it starts again knowing it can pass all the
3811 data directly through the decoder. Unfortunately it doesn't reset
3812 the context it uses. This means that if EOF is reached an attempt
3813 is made to pass two EOFs through the context and this causes the
3814 resulting error. This can also cause other problems as well. As is
3815 usual with these problems it takes *ages* to find and the fix is
3816 trivial: move one line.
3817 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
3819 *) Ugly workaround to get s_client and s_server working under Windows. The
3820 old code wouldn't work because it needed to select() on sockets and the
3821 tty (for keypresses and to see if data could be written). Win32 only
3822 supports select() on sockets so we select() with a 1s timeout on the
3823 sockets and then see if any characters are waiting to be read, if none
3824 are present then we retry, we also assume we can always write data to
3825 the tty. This isn't nice because the code then blocks until we've
3826 received a complete line of data and it is effectively polling the
3827 keyboard at 1s intervals: however it's quite a bit better than not
3828 working at all :-) A dedicated Windows application might handle this
3829 with an event loop for example.
3832 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
3833 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
3834 will be called when RSA_sign() and RSA_verify() are used. This is useful
3835 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
3836 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
3837 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
3838 This necessitated the support of an extra signature type NID_md5_sha1
3839 for SSL signatures and modifications to the SSL library to use it instead
3840 of calling RSA_public_decrypt() and RSA_private_encrypt().
3843 *) Add new -verify -CAfile and -CApath options to the crl program, these
3844 will lookup a CRL issuers certificate and verify the signature in a
3845 similar way to the verify program. Tidy up the crl program so it
3846 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
3847 less strict. It will now permit CRL extensions even if it is not
3848 a V2 CRL: this will allow it to tolerate some broken CRLs.
3851 *) Initialize all non-automatic variables each time one of the openssl
3852 sub-programs is started (this is necessary as they may be started
3853 multiple times from the "OpenSSL>" prompt).
3854 [Lennart Bang, Bodo Moeller]
3856 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
3857 removing all other RSA functionality (this is what NO_RSA does). This
3858 is so (for example) those in the US can disable those operations covered
3859 by the RSA patent while allowing storage and parsing of RSA keys and RSA
3863 *) Non-copying interface to BIO pairs.
3864 (still largely untested)
3867 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
3868 ASCII string. This was handled independently in various places before.
3871 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
3872 UTF8 strings a character at a time.
3875 *) Use client_version from client hello to select the protocol
3876 (s23_srvr.c) and for RSA client key exchange verification
3877 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
3880 *) Add various utility functions to handle SPKACs, these were previously
3881 handled by poking round in the structure internals. Added new function
3882 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
3883 print, verify and generate SPKACs. Based on an original idea from
3884 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
3887 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
3890 *) Allow the config file extension section to be overwritten on the
3891 command line. Based on an original idea from Massimiliano Pala
3892 <madwolf@comune.modena.it>. The new option is called -extensions
3893 and can be applied to ca, req and x509. Also -reqexts to override
3894 the request extensions in req and -crlexts to override the crl extensions
3898 *) Add new feature to the SPKAC handling in ca. Now you can include
3899 the same field multiple times by preceding it by "XXXX." for example:
3902 this is the same syntax as used in the req config file.
3905 *) Allow certificate extensions to be added to certificate requests. These
3906 are specified in a 'req_extensions' option of the req section of the
3907 config file. They can be printed out with the -text option to req but
3908 are otherwise ignored at present.
3911 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
3912 data read consists of only the final block it would not decrypted because
3913 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
3914 A misplaced 'break' also meant the decrypted final block might not be
3915 copied until the next read.
3918 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
3919 a few extra parameters to the DH structure: these will be useful if
3920 for example we want the value of 'q' or implement X9.42 DH.
3923 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
3924 provides hooks that allow the default DSA functions or functions on a
3925 "per key" basis to be replaced. This allows hardware acceleration and
3926 hardware key storage to be handled without major modification to the
3927 library. Also added low level modexp hooks and CRYPTO_EX structure and
3928 associated functions.
3931 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
3932 as "read only": it can't be written to and the buffer it points to will
3933 not be freed. Reading from a read only BIO is much more efficient than
3934 a normal memory BIO. This was added because there are several times when
3935 an area of memory needs to be read from a BIO. The previous method was
3936 to create a memory BIO and write the data to it, this results in two
3937 copies of the data and an O(n^2) reading algorithm. There is a new
3938 function BIO_new_mem_buf() which creates a read only memory BIO from
3939 an area of memory. Also modified the PKCS#7 routines to use read only
3943 *) Bugfix: ssl23_get_client_hello did not work properly when called in
3944 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
3945 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
3946 but a retry condition occured while trying to read the rest.
3949 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
3950 NID_pkcs7_encrypted by default: this was wrong since this should almost
3951 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
3952 the encrypted data type: this is a more sensible place to put it and it
3953 allows the PKCS#12 code to be tidied up that duplicated this
3957 *) Changed obj_dat.pl script so it takes its input and output files on
3958 the command line. This should avoid shell escape redirection problems
3962 *) Initial support for certificate extension requests, these are included
3963 in things like Xenroll certificate requests. Included functions to allow
3964 extensions to be obtained and added.
3967 *) -crlf option to s_client and s_server for sending newlines as
3968 CRLF (as required by many protocols).
3971 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
3973 *) Install libRSAglue.a when OpenSSL is built with RSAref.
3974 [Ralf S. Engelschall]
3976 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
3977 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
3979 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
3983 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
3984 DH parameters/keys (q is lost during that conversion, but the resulting
3985 DH parameters contain its length).
3987 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
3988 much faster than DH_generate_parameters (which creates parameters
3989 where p = 2*q + 1), and also the smaller q makes DH computations
3990 much more efficient (160-bit exponentiation instead of 1024-bit
3991 exponentiation); so this provides a convenient way to support DHE
3992 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
3993 utter importance to use
3994 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3996 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3997 when such DH parameters are used, because otherwise small subgroup
3998 attacks may become possible!
4001 *) Avoid memory leak in i2d_DHparams.
4004 *) Allow the -k option to be used more than once in the enc program:
4005 this allows the same encrypted message to be read by multiple recipients.
4008 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
4009 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
4010 it will always use the numerical form of the OID, even if it has a short
4014 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
4015 method only got called if p,q,dmp1,dmq1,iqmp components were present,
4016 otherwise bn_mod_exp was called. In the case of hardware keys for example
4017 no private key components need be present and it might store extra data
4018 in the RSA structure, which cannot be accessed from bn_mod_exp.
4019 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
4020 private key operations.
4023 *) Added support for SPARC Linux.
4026 *) pem_password_cb function type incompatibly changed from
4027 typedef int pem_password_cb(char *buf, int size, int rwflag);
4029 ....(char *buf, int size, int rwflag, void *userdata);
4030 so that applications can pass data to their callbacks:
4031 The PEM[_ASN1]_{read,write}... functions and macros now take an
4032 additional void * argument, which is just handed through whenever
4033 the password callback is called.
4034 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
4036 New function SSL_CTX_set_default_passwd_cb_userdata.
4038 Compatibility note: As many C implementations push function arguments
4039 onto the stack in reverse order, the new library version is likely to
4040 interoperate with programs that have been compiled with the old
4041 pem_password_cb definition (PEM_whatever takes some data that
4042 happens to be on the stack as its last argument, and the callback
4043 just ignores this garbage); but there is no guarantee whatsoever that
4046 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
4047 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
4048 problems not only on Windows, but also on some Unix platforms.
4049 To avoid problematic command lines, these definitions are now in an
4050 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
4051 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
4054 *) MIPS III/IV assembler module is reimplemented.
4057 *) More DES library cleanups: remove references to srand/rand and
4058 delete an unused file.
4061 *) Add support for the the free Netwide assembler (NASM) under Win32,
4062 since not many people have MASM (ml) and it can be hard to obtain.
4063 This is currently experimental but it seems to work OK and pass all
4064 the tests. Check out INSTALL.W32 for info.
4067 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
4068 without temporary keys kept an extra copy of the server key,
4069 and connections with temporary keys did not free everything in case
4073 *) New function RSA_check_key and new openssl rsa option -check
4074 for verifying the consistency of RSA keys.
4075 [Ulf Moeller, Bodo Moeller]
4077 *) Various changes to make Win32 compile work:
4078 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
4079 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
4080 comparison" warnings.
4081 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
4084 *) Add a debugging option to PKCS#5 v2 key generation function: when
4085 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
4086 derived keys are printed to stderr.
4089 *) Copy the flags in ASN1_STRING_dup().
4090 [Roman E. Pavlov <pre@mo.msk.ru>]
4092 *) The x509 application mishandled signing requests containing DSA
4093 keys when the signing key was also DSA and the parameters didn't match.
4095 It was supposed to omit the parameters when they matched the signing key:
4096 the verifying software was then supposed to automatically use the CA's
4097 parameters if they were absent from the end user certificate.
4099 Omitting parameters is no longer recommended. The test was also
4100 the wrong way round! This was probably due to unusual behaviour in
4101 EVP_cmp_parameters() which returns 1 if the parameters match.
4102 This meant that parameters were omitted when they *didn't* match and
4103 the certificate was useless. Certificates signed with 'ca' didn't have
4105 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
4107 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
4108 The interface is as follows:
4109 Applications can use
4110 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
4111 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
4112 "off" is now the default.
4113 The library internally uses
4114 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
4115 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
4116 to disable memory-checking temporarily.
4118 Some inconsistent states that previously were possible (and were
4119 even the default) are now avoided.
4121 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
4122 with each memory chunk allocated; this is occasionally more helpful
4123 than just having a counter.
4125 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
4127 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
4131 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
4132 which largely parallels "options", but is for changing API behaviour,
4133 whereas "options" are about protocol behaviour.
4134 Initial "mode" flags are:
4136 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
4137 a single record has been written.
4138 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
4139 retries use the same buffer location.
4140 (But all of the contents must be
4144 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
4147 *) Fix problems with no-hmac etc.
4148 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
4150 *) New functions RSA_get_default_method(), RSA_set_method() and
4151 RSA_get_method(). These allows replacement of RSA_METHODs without having
4152 to mess around with the internals of an RSA structure.
4155 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
4156 Also really enable memory leak checks in openssl.c and in some
4158 [Chad C. Mulligan, Bodo Moeller]
4160 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
4161 up the length of negative integers. This has now been simplified to just
4162 store the length when it is first determined and use it later, rather
4163 than trying to keep track of where data is copied and updating it to
4165 [Steve Henson, reported by Brien Wheeler
4166 <bwheeler@authentica-security.com>]
4168 *) Add a new function PKCS7_signatureVerify. This allows the verification
4169 of a PKCS#7 signature but with the signing certificate passed to the
4170 function itself. This contrasts with PKCS7_dataVerify which assumes the
4171 certificate is present in the PKCS#7 structure. This isn't always the
4172 case: certificates can be omitted from a PKCS#7 structure and be
4173 distributed by "out of band" means (such as a certificate database).
4176 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
4177 function prototypes in pem.h, also change util/mkdef.pl to add the
4178 necessary function names.
4181 *) mk1mf.pl (used by Windows builds) did not properly read the
4182 options set by Configure in the top level Makefile, and Configure
4183 was not even able to write more than one option correctly.
4184 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
4187 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
4188 file to be loaded from a BIO or FILE pointer. The BIO version will
4189 for example allow memory BIOs to contain config info.
4192 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
4193 Whoever hopes to achieve shared-library compatibility across versions
4194 must use this, not the compile-time macro.
4195 (Exercise 0.9.4: Which is the minimum library version required by
4197 Note: All this applies only to multi-threaded programs, others don't
4201 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
4202 through a BIO pair triggered the default case, i.e.
4203 SSLerr(...,SSL_R_UNKNOWN_STATE).
4206 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
4207 can use the SSL library even if none of the specific BIOs is
4211 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
4212 for the encoded length.
4213 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
4215 *) Add initial documentation of the X509V3 functions.
4218 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
4219 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
4220 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
4221 secure PKCS#8 private key format with a high iteration count.
4224 *) Fix determination of Perl interpreter: A perl or perl5
4225 _directory_ in $PATH was also accepted as the interpreter.
4226 [Ralf S. Engelschall]
4228 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
4229 wrong with it but it was very old and did things like calling
4230 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
4234 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
4235 to use the new extension code.
4238 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
4239 with macros. This should make it easier to change their form, add extra
4240 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
4244 *) Add to configuration table a new entry that can specify an alternative
4245 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
4246 according to Mark Crispin <MRC@Panda.COM>.
4250 *) DES CBC did not update the IV. Weird.
4253 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
4254 Changing the behaviour of the former might break existing programs --
4255 where IV updating is needed, des_ncbc_encrypt can be used.
4258 *) When bntest is run from "make test" it drives bc to check its
4259 calculations, as well as internally checking them. If an internal check
4260 fails, it needs to cause bc to give a non-zero result or make test carries
4261 on without noticing the failure. Fixed.
4264 *) DES library cleanups.
4267 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
4268 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
4269 ciphers. NOTE: although the key derivation function has been verified
4270 against some published test vectors it has not been extensively tested
4271 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
4275 *) Instead of "mkdir -p", which is not fully portable, use new
4276 Perl script "util/mkdir-p.pl".
4279 *) Rewrite the way password based encryption (PBE) is handled. It used to
4280 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
4281 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
4282 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
4283 the 'parameter' field of the AlgorithmIdentifier is passed to the
4284 underlying key generation function so it must do its own ASN1 parsing.
4285 This has also changed the EVP_PBE_CipherInit() function which now has a
4286 'parameter' argument instead of literal salt and iteration count values
4287 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
4290 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
4291 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
4292 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
4293 KEY" because this clashed with PKCS#8 unencrypted string. Since this
4294 value was just used as a "magic string" and not used directly its
4295 value doesn't matter.
4298 *) Introduce some semblance of const correctness to BN. Shame C doesn't
4302 *) "linux-sparc64" configuration (ultrapenguin).
4303 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
4304 "linux-sparc" configuration.
4305 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
4307 *) config now generates no-xxx options for missing ciphers.
4310 *) Support the EBCDIC character set (work in progress).
4311 File ebcdic.c not yet included because it has a different license.
4312 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4314 *) Support BS2000/OSD-POSIX.
4315 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4317 *) Make callbacks for key generation use void * instead of char *.
4320 *) Make S/MIME samples compile (not yet tested).
4323 *) Additional typesafe stacks.
4326 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
4330 Changes between 0.9.3 and 0.9.3a [29 May 1999]
4332 *) New configuration variant "sco5-gcc".
4334 *) Updated some demos.
4335 [Sean O Riordain, Wade Scholine]
4337 *) Add missing BIO_free at exit of pkcs12 application.
4340 *) Fix memory leak in conf.c.
4343 *) Updates for Win32 to assembler version of MD5.
4346 *) Set #! path to perl in apps/der_chop to where we found it
4347 instead of using a fixed path.
4350 *) SHA library changes for irix64-mips4-cc.
4353 *) Improvements for VMS support.
4357 Changes between 0.9.2b and 0.9.3 [24 May 1999]
4359 *) Bignum library bug fix. IRIX 6 passes "make test" now!
4360 This also avoids the problems with SC4.2 and unpatched SC5.
4361 [Andy Polyakov <appro@fy.chalmers.se>]
4363 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
4364 These are required because of the typesafe stack would otherwise break
4365 existing code. If old code used a structure member which used to be STACK
4366 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
4367 sk_num or sk_value it would produce an error because the num, data members
4368 are not present in STACK_OF. Now it just produces a warning. sk_set
4369 replaces the old method of assigning a value to sk_value
4370 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
4371 that does this will no longer work (and should use sk_set instead) but
4372 this could be regarded as a "questionable" behaviour anyway.
4375 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
4376 correctly handle encrypted S/MIME data.
4379 *) Change type of various DES function arguments from des_cblock
4380 (which means, in function argument declarations, pointer to char)
4381 to des_cblock * (meaning pointer to array with 8 char elements),
4382 which allows the compiler to do more typechecking; it was like
4383 that back in SSLeay, but with lots of ugly casts.
4385 Introduce new type const_des_cblock.
4388 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
4389 problems: find RecipientInfo structure that matches recipient certificate
4390 and initialise the ASN1 structures properly based on passed cipher.
4393 *) Belatedly make the BN tests actually check the results.
4396 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
4397 to and from BNs: it was completely broken. New compilation option
4398 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
4399 key elements as negative integers.
4402 *) Reorganize and speed up MD5.
4403 [Andy Polyakov <appro@fy.chalmers.se>]
4406 [Richard Levitte <richard@levitte.org>]
4408 *) New option -out to asn1parse to allow the parsed structure to be
4409 output to a file. This is most useful when combined with the -strparse
4410 option to examine the output of things like OCTET STRINGS.
4413 *) Make SSL library a little more fool-proof by not requiring any longer
4414 that SSL_set_{accept,connect}_state be called before
4415 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
4416 in many applications because usually everything *appeared* to work as
4417 intended anyway -- now it really works as intended).
4420 *) Move openssl.cnf out of lib/.
4423 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
4424 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
4425 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
4426 [Ralf S. Engelschall]
4428 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
4429 handle PKCS#7 enveloped data properly.
4430 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
4432 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
4433 copying pointers. The cert_st handling is changed by this in
4434 various ways (and thus what used to be known as ctx->default_cert
4435 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
4436 any longer when s->cert does not give us what we need).
4437 ssl_cert_instantiate becomes obsolete by this change.
4438 As soon as we've got the new code right (possibly it already is?),
4439 we have solved a couple of bugs of the earlier code where s->cert
4440 was used as if it could not have been shared with other SSL structures.
4442 Note that using the SSL API in certain dirty ways now will result
4443 in different behaviour than observed with earlier library versions:
4444 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
4445 does not influence s as it used to.
4447 In order to clean up things more thoroughly, inside SSL_SESSION
4448 we don't use CERT any longer, but a new structure SESS_CERT
4449 that holds per-session data (if available); currently, this is
4450 the peer's certificate chain and, for clients, the server's certificate
4451 and temporary key. CERT holds only those values that can have
4452 meaningful defaults in an SSL_CTX.
4455 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
4456 from the internal representation. Various PKCS#7 fixes: remove some
4457 evil casts and set the enc_dig_alg field properly based on the signing
4461 *) Allow PKCS#12 password to be set from the command line or the
4462 environment. Let 'ca' get its config file name from the environment
4463 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
4467 *) Allow certificate policies extension to use an IA5STRING for the
4468 organization field. This is contrary to the PKIX definition but
4469 VeriSign uses it and IE5 only recognises this form. Document 'x509'
4473 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
4474 without disallowing inline assembler and the like for non-pedantic builds.
4477 *) Support Borland C++ builder.
4478 [Janez Jere <jj@void.si>, modified by Ulf Möller]
4483 *) SHA-1 cleanups and performance enhancements.
4484 [Andy Polyakov <appro@fy.chalmers.se>]
4486 *) Sparc v8plus assembler for the bignum library.
4487 [Andy Polyakov <appro@fy.chalmers.se>]
4489 *) Accept any -xxx and +xxx compiler options in Configure.
4492 *) Update HPUX configuration.
4495 *) Add missing sk_<type>_unshift() function to safestack.h
4496 [Ralf S. Engelschall]
4498 *) New function SSL_CTX_use_certificate_chain_file that sets the
4499 "extra_cert"s in addition to the certificate. (This makes sense
4500 only for "PEM" format files, as chains as a whole are not
4504 *) Support verify_depth from the SSL API.
4505 x509_vfy.c had what can be considered an off-by-one-error:
4506 Its depth (which was not part of the external interface)
4507 was actually counting the number of certificates in a chain;
4508 now it really counts the depth.
4511 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
4512 instead of X509err, which often resulted in confusing error
4513 messages since the error codes are not globally unique
4514 (e.g. an alleged error in ssl3_accept when a certificate
4515 didn't match the private key).
4517 *) New function SSL_CTX_set_session_id_context that allows to set a default
4518 value (so that you don't need SSL_set_session_id_context for each
4519 connection using the SSL_CTX).
4522 *) OAEP decoding bug fix.
4525 *) Support INSTALL_PREFIX for package builders, as proposed by
4529 *) New Configure options "threads" and "no-threads". For systems
4530 where the proper compiler options are known (currently Solaris
4531 and Linux), "threads" is the default.
4534 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
4537 *) Install various scripts to $(OPENSSLDIR)/misc, not to
4538 $(INSTALLTOP)/bin -- they shouldn't clutter directories
4539 such as /usr/local/bin.
4542 *) "make linux-shared" to build shared libraries.
4543 [Niels Poppe <niels@netbox.org>]
4545 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
4548 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
4549 extension adding in x509 utility.
4552 *) Remove NOPROTO sections and error code comments.
4555 *) Partial rewrite of the DEF file generator to now parse the ANSI
4559 *) New Configure options --prefix=DIR and --openssldir=DIR.
4562 *) Complete rewrite of the error code script(s). It is all now handled
4563 by one script at the top level which handles error code gathering,
4564 header rewriting and C source file generation. It should be much better
4565 than the old method: it now uses a modified version of Ulf's parser to
4566 read the ANSI prototypes in all header files (thus the old K&R definitions
4567 aren't needed for error creation any more) and do a better job of
4568 translating function codes into names. The old 'ASN1 error code imbedded
4569 in a comment' is no longer necessary and it doesn't use .err files which
4570 have now been deleted. Also the error code call doesn't have to appear all
4571 on one line (which resulted in some large lines...).
4574 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
4577 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
4578 0 (which usually indicates a closed connection), but continue reading.
4581 *) Fix some race conditions.
4584 *) Add support for CRL distribution points extension. Add Certificate
4585 Policies and CRL distribution points documentation.
4588 *) Move the autogenerated header file parts to crypto/opensslconf.h.
4591 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
4592 8 of keying material. Merlin has also confirmed interop with this fix
4593 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
4594 [Merlin Hughes <merlin@baltimore.ie>]
4596 *) Fix lots of warnings.
4597 [Richard Levitte <levitte@stacken.kth.se>]
4599 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
4600 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
4601 [Richard Levitte <levitte@stacken.kth.se>]
4603 *) Fix problems with sizeof(long) == 8.
4604 [Andy Polyakov <appro@fy.chalmers.se>]
4606 *) Change functions to ANSI C.
4609 *) Fix typos in error codes.
4610 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
4612 *) Remove defunct assembler files from Configure.
4615 *) SPARC v8 assembler BIGNUM implementation.
4616 [Andy Polyakov <appro@fy.chalmers.se>]
4618 *) Support for Certificate Policies extension: both print and set.
4619 Various additions to support the r2i method this uses.
4622 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
4623 return a const string when you are expecting an allocated buffer.
4626 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
4627 types DirectoryString and DisplayText.
4630 *) Add code to allow r2i extensions to access the configuration database,
4631 add an LHASH database driver and add several ctx helper functions.
4634 *) Fix an evil bug in bn_expand2() which caused various BN functions to
4635 fail when they extended the size of a BIGNUM.
4638 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
4639 support typesafe stack.
4642 *) Fix typo in SSL_[gs]et_options().
4643 [Nils Frostberg <nils@medcom.se>]
4645 *) Delete various functions and files that belonged to the (now obsolete)
4646 old X509V3 handling code.
4649 *) New Configure option "rsaref".
4652 *) Don't auto-generate pem.h.
4655 *) Introduce type-safe ASN.1 SETs.
4658 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
4659 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
4661 *) Introduce type-safe STACKs. This will almost certainly break lots of code
4662 that links with OpenSSL (well at least cause lots of warnings), but fear
4663 not: the conversion is trivial, and it eliminates loads of evil casts. A
4664 few STACKed things have been converted already. Feel free to convert more.
4665 In the fullness of time, I'll do away with the STACK type altogether.
4668 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
4669 specified in <certfile> by updating the entry in the index.txt file.
4670 This way one no longer has to edit the index.txt file manually for
4671 revoking a certificate. The -revoke option does the gory details now.
4672 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
4674 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
4675 `-text' option at all and this way the `-noout -text' combination was
4676 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
4677 [Ralf S. Engelschall]
4679 *) Make sure a corresponding plain text error message exists for the
4680 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
4681 verify callback function determined that a certificate was revoked.
4682 [Ralf S. Engelschall]
4684 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
4685 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
4686 all available cipers including rc5, which was forgotten until now.
4687 In order to let the testing shell script know which algorithms
4688 are available, a new (up to now undocumented) command
4689 "openssl list-cipher-commands" is used.
4692 *) Bugfix: s_client occasionally would sleep in select() when
4693 it should have checked SSL_pending() first.
4696 *) New functions DSA_do_sign and DSA_do_verify to provide access to
4697 the raw DSA values prior to ASN.1 encoding.
4700 *) Tweaks to Configure
4701 [Niels Poppe <niels@netbox.org>]
4703 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
4707 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
4710 *) New config option to avoid instructions that are illegal on the 80386.
4711 The default code is faster, but requires at least a 486.
4714 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
4715 SSL2_SERVER_VERSION (not used at all) macros, which are now the
4716 same as SSL2_VERSION anyway.
4719 *) New "-showcerts" option for s_client.
4722 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
4723 application. Various cleanups and fixes.
4726 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
4727 modify error routines to work internally. Add error codes and PBE init
4728 to library startup routines.
4731 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
4732 packing functions to asn1 and evp. Changed function names and error
4733 codes along the way.
4736 *) PKCS12 integration: and so it begins... First of several patches to
4737 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
4738 objects to objects.h
4741 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
4742 and display support for Thawte strong extranet extension.
4745 *) Add LinuxPPC support.
4746 [Jeff Dubrule <igor@pobox.org>]
4748 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
4749 bn_div_words in alpha.s.
4750 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
4752 *) Make sure the RSA OAEP test is skipped under -DRSAref because
4753 OAEP isn't supported when OpenSSL is built with RSAref.
4754 [Ulf Moeller <ulf@fitug.de>]
4756 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
4757 so they no longer are missing under -DNOPROTO.
4758 [Soren S. Jorvang <soren@t.dk>]
4761 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
4763 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
4764 doesn't work when the session is reused. Coming soon!
4767 *) Fix a security hole, that allows sessions to be reused in the wrong
4768 context thus bypassing client cert protection! All software that uses
4769 client certs and session caches in multiple contexts NEEDS PATCHING to
4770 allow session reuse! A fuller solution is in the works.
4771 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
4773 *) Some more source tree cleanups (removed obsolete files
4774 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
4775 permission on "config" script to be executable) and a fix for the INSTALL
4777 [Ulf Moeller <ulf@fitug.de>]
4779 *) Remove some legacy and erroneous uses of malloc, free instead of
4781 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
4783 *) Make rsa_oaep_test return non-zero on error.
4784 [Ulf Moeller <ulf@fitug.de>]
4786 *) Add support for native Solaris shared libraries. Configure
4787 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
4788 if someone would make that last step automatic.
4789 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
4791 *) ctx_size was not built with the right compiler during "make links". Fixed.
4794 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
4795 except NULL ciphers". This means the default cipher list will no longer
4796 enable NULL ciphers. They need to be specifically enabled e.g. with
4797 the string "DEFAULT:eNULL".
4800 *) Fix to RSA private encryption routines: if p < q then it would
4801 occasionally produce an invalid result. This will only happen with
4802 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
4805 *) Be less restrictive and allow also `perl util/perlpath.pl
4806 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
4807 because this way one can also use an interpreter named `perl5' (which is
4808 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
4809 installed as `perl').
4810 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4812 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
4813 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4815 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
4816 advapi32.lib to Win32 build and change the pem test comparision
4817 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
4818 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
4819 and crypto/des/ede_cbcm_enc.c.
4822 *) DES quad checksum was broken on big-endian architectures. Fixed.
4825 *) Comment out two functions in bio.h that aren't implemented. Fix up the
4826 Win32 test batch file so it (might) work again. The Win32 test batch file
4827 is horrible: I feel ill....
4830 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
4831 in e_os.h. Audit of header files to check ANSI and non ANSI
4832 sections: 10 functions were absent from non ANSI section and not exported
4833 from Windows DLLs. Fixed up libeay.num for new functions.
4836 *) Make `openssl version' output lines consistent.
4837 [Ralf S. Engelschall]
4839 *) Fix Win32 symbol export lists for BIO functions: Added
4840 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
4841 to ms/libeay{16,32}.def.
4842 [Ralf S. Engelschall]
4844 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
4845 fine under Unix and passes some trivial tests I've now added. But the
4846 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
4847 added to make sure no one expects that this stuff really works in the
4848 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
4849 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
4851 [Ralf S. Engelschall]
4853 *) Fix the generation of two part addresses in perl.
4854 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
4856 *) Add config entry for Linux on MIPS.
4857 [John Tobey <jtobey@channel1.com>]
4859 *) Make links whenever Configure is run, unless we are on Windoze.
4862 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
4863 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
4867 *) Add a useful kludge to allow package maintainers to specify compiler and
4868 other platforms details on the command line without having to patch the
4869 Configure script everytime: One now can use ``perl Configure
4870 <id>:<details>'', i.e. platform ids are allowed to have details appended
4871 to them (seperated by colons). This is treated as there would be a static
4872 pre-configured entry in Configure's %table under key <id> with value
4873 <details> and ``perl Configure <id>'' is called. So, when you want to
4874 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
4875 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
4876 now, which overrides the FreeBSD-elf entry on-the-fly.
4877 [Ralf S. Engelschall]
4879 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
4882 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
4883 on the `perl Configure ...' command line. This way one can compile
4884 OpenSSL libraries with Position Independent Code (PIC) which is needed
4885 for linking it into DSOs.
4886 [Ralf S. Engelschall]
4888 *) Remarkably, export ciphers were totally broken and no-one had noticed!
4892 *) Cleaned up the LICENSE document: The official contact for any license
4893 questions now is the OpenSSL core team under openssl-core@openssl.org.
4894 And add a paragraph about the dual-license situation to make sure people
4895 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
4896 to the OpenSSL toolkit.
4897 [Ralf S. Engelschall]
4899 *) General source tree makefile cleanups: Made `making xxx in yyy...'
4900 display consistent in the source tree and replaced `/bin/rm' by `rm'.
4901 Additonally cleaned up the `make links' target: Remove unnecessary
4902 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
4903 to speed processing and no longer clutter the display with confusing
4904 stuff. Instead only the actually done links are displayed.
4905 [Ralf S. Engelschall]
4907 *) Permit null encryption ciphersuites, used for authentication only. It used
4908 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
4909 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
4913 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
4914 signed attributes when verifying signatures (this would break them),
4915 the detached data encoding was wrong and public keys obtained using
4916 X509_get_pubkey() weren't freed.
4919 *) Add text documentation for the BUFFER functions. Also added a work around
4920 to a Win95 console bug. This was triggered by the password read stuff: the
4921 last character typed gets carried over to the next fread(). If you were
4922 generating a new cert request using 'req' for example then the last
4923 character of the passphrase would be CR which would then enter the first
4927 *) Added the new `Includes OpenSSL Cryptography Software' button as
4928 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
4929 button and can be used by applications based on OpenSSL to show the
4930 relationship to the OpenSSL project.
4931 [Ralf S. Engelschall]
4933 *) Remove confusing variables in function signatures in files
4934 ssl/ssl_lib.c and ssl/ssl.h.
4935 [Lennart Bong <lob@kulthea.stacken.kth.se>]
4937 *) Don't install bss_file.c under PREFIX/include/
4938 [Lennart Bong <lob@kulthea.stacken.kth.se>]
4940 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
4941 functions that return function pointers and has support for NT specific
4942 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
4943 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
4944 unsigned to signed types: this was killing the Win32 compile.
4947 *) Add new certificate file to stack functions,
4948 SSL_add_dir_cert_subjects_to_stack() and
4949 SSL_add_file_cert_subjects_to_stack(). These largely supplant
4950 SSL_load_client_CA_file(), and can be used to add multiple certs easily
4951 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
4952 This means that Apache-SSL and similar packages don't have to mess around
4953 to add as many CAs as they want to the preferred list.
4956 *) Experiment with doxygen documentation. Currently only partially applied to
4958 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
4959 openssl.doxy as the configuration file.
4962 *) Get rid of remaining C++-style comments which strict C compilers hate.
4963 [Ralf S. Engelschall, pointed out by Carlos Amengual]
4965 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
4966 compiled in by default: it has problems with large keys.
4969 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
4970 DH private keys and/or callback functions which directly correspond to
4971 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
4972 is needed for applications which have to configure certificates on a
4973 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
4975 For the RSA certificate situation is makes no difference, but
4976 for the DSA certificate situation this fixes the "no shared cipher"
4977 problem where the OpenSSL cipher selection procedure failed because the
4978 temporary keys were not overtaken from the context and the API provided
4979 no way to reconfigure them.
4980 The new functions now let applications reconfigure the stuff and they
4981 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
4982 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
4983 non-public-API function ssl_cert_instantiate() is used as a helper
4984 function and also to reduce code redundancy inside ssl_rsa.c.
4985 [Ralf S. Engelschall]
4987 *) Move s_server -dcert and -dkey options out of the undocumented feature
4988 area because they are useful for the DSA situation and should be
4989 recognized by the users.
4990 [Ralf S. Engelschall]
4992 *) Fix the cipher decision scheme for export ciphers: the export bits are
4993 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
4994 SSL_EXP_MASK. So, the original variable has to be used instead of the
4995 already masked variable.
4996 [Richard Levitte <levitte@stacken.kth.se>]
4998 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
4999 [Richard Levitte <levitte@stacken.kth.se>]
5001 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
5002 from `int' to `unsigned int' because it's a length and initialized by
5003 EVP_DigestFinal() which expects an `unsigned int *'.
5004 [Richard Levitte <levitte@stacken.kth.se>]
5006 *) Don't hard-code path to Perl interpreter on shebang line of Configure
5007 script. Instead use the usual Shell->Perl transition trick.
5008 [Ralf S. Engelschall]
5010 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
5011 (in addition to RSA certificates) to match the behaviour of `openssl dsa
5012 -noout -modulus' as it's already the case for `openssl rsa -noout
5013 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
5014 currently the public key is printed (a decision which was already done by
5015 `openssl dsa -modulus' in the past) which serves a similar purpose.
5016 Additionally the NO_RSA no longer completely removes the whole -modulus
5017 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
5019 [Ralf S. Engelschall]
5021 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
5022 BIO. See the source (crypto/evp/bio_ok.c) for more info.
5023 [Arne Ansper <arne@ats.cyber.ee>]
5025 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
5026 to be added. Now both 'req' and 'ca' can use new objects defined in the
5030 *) Add cool BIO that does syslog (or event log on NT).
5031 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
5033 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
5034 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
5035 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
5036 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
5039 *) Add preliminary config info for new extension code.
5042 *) Make RSA_NO_PADDING really use no padding.
5043 [Ulf Moeller <ulf@fitug.de>]
5045 *) Generate errors when private/public key check is done.
5048 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
5049 for some CRL extensions and new objects added.
5052 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
5053 key usage extension and fuller support for authority key id.
5056 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
5057 padding method for RSA, which is recommended for new applications in PKCS
5058 #1 v2.0 (RFC 2437, October 1998).
5059 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
5060 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
5061 against Bleichbacher's attack on RSA.
5062 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
5065 *) Updates to the new SSL compression code
5066 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5068 *) Fix so that the version number in the master secret, when passed
5069 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
5070 (because the server will not accept higher), that the version number
5071 is 0x03,0x01, not 0x03,0x00
5072 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5074 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
5075 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
5076 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
5079 *) Support for RAW extensions where an arbitrary extension can be
5080 created by including its DER encoding. See apps/openssl.cnf for
5084 *) Make sure latest Perl versions don't interpret some generated C array
5085 code as Perl array code in the crypto/err/err_genc.pl script.
5086 [Lars Weber <3weber@informatik.uni-hamburg.de>]
5088 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
5089 not many people have the assembler. Various Win32 compilation fixes and
5090 update to the INSTALL.W32 file with (hopefully) more accurate Win32
5094 *) Modify configure script 'Configure' to automatically create crypto/date.h
5095 file under Win32 and also build pem.h from pem.org. New script
5096 util/mkfiles.pl to create the MINFO file on environments that can't do a
5097 'make files': perl util/mkfiles.pl >MINFO should work.
5100 *) Major rework of DES function declarations, in the pursuit of correctness
5101 and purity. As a result, many evil casts evaporated, and some weirdness,
5102 too. You may find this causes warnings in your code. Zapping your evil
5103 casts will probably fix them. Mostly.
5106 *) Fix for a typo in asn1.h. Bug fix to object creation script
5107 obj_dat.pl. It considered a zero in an object definition to mean
5108 "end of object": none of the objects in objects.h have any zeros
5109 so it wasn't spotted.
5110 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
5112 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
5113 Masking (CBCM). In the absence of test vectors, the best I have been able
5114 to do is check that the decrypt undoes the encrypt, so far. Send me test
5115 vectors if you have them.
5118 *) Correct calculation of key length for export ciphers (too much space was
5119 allocated for null ciphers). This has not been tested!
5122 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
5123 message is now correct (it understands "crypto" and "ssl" on its
5124 command line). There is also now an "update" option. This will update
5125 the util/ssleay.num and util/libeay.num files with any new functions.
5127 perl util/mkdef.pl crypto ssl update
5128 it will update them.
5131 *) Overhauled the Perl interface (perl/*):
5132 - ported BN stuff to OpenSSL's different BN library
5133 - made the perl/ source tree CVS-aware
5134 - renamed the package from SSLeay to OpenSSL (the files still contain
5135 their history because I've copied them in the repository)
5136 - removed obsolete files (the test scripts will be replaced
5137 by better Test::Harness variants in the future)
5138 [Ralf S. Engelschall]
5140 *) First cut for a very conservative source tree cleanup:
5141 1. merge various obsolete readme texts into doc/ssleay.txt
5142 where we collect the old documents and readme texts.
5143 2. remove the first part of files where I'm already sure that we no
5144 longer need them because of three reasons: either they are just temporary
5145 files which were left by Eric or they are preserved original files where
5146 I've verified that the diff is also available in the CVS via "cvs diff
5147 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
5148 the crypto/md/ stuff).
5149 [Ralf S. Engelschall]
5151 *) More extension code. Incomplete support for subject and issuer alt
5152 name, issuer and authority key id. Change the i2v function parameters
5153 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
5154 what that's for :-) Fix to ASN1 macro which messed up
5155 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
5158 *) Preliminary support for ENUMERATED type. This is largely copied from the
5162 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
5163 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5165 *) Make sure `make rehash' target really finds the `openssl' program.
5166 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5168 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
5169 like to hear about it if this slows down other processors.
5172 *) Add CygWin32 platform information to Configure script.
5173 [Alan Batie <batie@aahz.jf.intel.com>]
5175 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
5176 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
5178 *) New program nseq to manipulate netscape certificate sequences
5181 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
5185 *) Fixes to BN code. Previously the default was to define BN_RECURSION
5186 but the BN code had some problems that would cause failures when
5187 doing certificate verification and some other functions.
5188 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5190 *) Add ASN1 and PEM code to support netscape certificate sequences.
5193 *) Add ASN1 and PEM code to support netscape certificate sequences.
5196 *) Add several PKIX and private extended key usage OIDs.
5199 *) Modify the 'ca' program to handle the new extension code. Modify
5200 openssl.cnf for new extension format, add comments.
5203 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
5204 and add a sample to openssl.cnf so req -x509 now adds appropriate
5208 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
5209 error code, add initial support to X509_print() and x509 application.
5212 *) Takes a deep breath and start addding X509 V3 extension support code. Add
5213 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
5214 stuff is currently isolated and isn't even compiled yet.
5217 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
5218 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
5219 Removed the versions check from X509 routines when loading extensions:
5220 this allows certain broken certificates that don't set the version
5221 properly to be processed.
5224 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
5225 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
5226 can still be regenerated with "make depend".
5229 *) Spelling mistake in C version of CAST-128.
5230 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
5232 *) Changes to the error generation code. The perl script err-code.pl
5233 now reads in the old error codes and retains the old numbers, only
5234 adding new ones if necessary. It also only changes the .err files if new
5235 codes are added. The makefiles have been modified to only insert errors
5236 when needed (to avoid needlessly modifying header files). This is done
5237 by only inserting errors if the .err file is newer than the auto generated
5238 C file. To rebuild all the error codes from scratch (the old behaviour)
5239 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
5240 or delete all the .err files.
5243 *) CAST-128 was incorrectly implemented for short keys. The C version has
5244 been fixed, but is untested. The assembler versions are also fixed, but
5245 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
5246 to regenerate it if needed.
5247 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
5248 Hagino <itojun@kame.net>]
5250 *) File was opened incorrectly in randfile.c.
5251 [Ulf Möller <ulf@fitug.de>]
5253 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
5254 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
5255 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
5256 al: it's just almost always a UTCTime. Note this patch adds new error
5257 codes so do a "make errors" if there are problems.
5260 *) Correct Linux 1 recognition in config.
5261 [Ulf Möller <ulf@fitug.de>]
5263 *) Remove pointless MD5 hash when using DSA keys in ca.
5264 [Anonymous <nobody@replay.com>]
5266 *) Generate an error if given an empty string as a cert directory. Also
5267 generate an error if handed NULL (previously returned 0 to indicate an
5268 error, but didn't set one).
5269 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
5271 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
5274 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
5275 parameters. This was causing a warning which killed off the Win32 compile.
5278 *) Remove C++ style comments from crypto/bn/bn_local.h.
5279 [Neil Costigan <neil.costigan@celocom.com>]
5281 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
5282 based on a text string, looking up short and long names and finally
5283 "dot" format. The "dot" format stuff didn't work. Added new function
5284 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
5285 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
5286 OID is not part of the table.
5289 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
5290 X509_LOOKUP_by_alias().
5293 *) Sort openssl functions by name.
5296 *) Get the gendsa program working (hopefully) and add it to app list. Remove
5297 encryption from sample DSA keys (in case anyone is interested the password
5301 *) Make _all_ *_free functions accept a NULL pointer.
5302 [Frans Heymans <fheymans@isaserver.be>]
5304 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
5306 [Anonymous <nobody@replay.com>]
5308 *) s_server should send the CAfile as acceptable CAs, not its own cert.
5309 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
5311 *) Don't blow it for numeric -newkey arguments to apps/req.
5312 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
5314 *) Temp key "for export" tests were wrong in s3_srvr.c.
5315 [Anonymous <nobody@replay.com>]
5317 *) Add prototype for temp key callback functions
5318 SSL_CTX_set_tmp_{rsa,dh}_callback().
5321 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
5322 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
5325 *) X509_name_add_entry() freed the wrong thing after an error.
5326 [Arne Ansper <arne@ats.cyber.ee>]
5328 *) rsa_eay.c would attempt to free a NULL context.
5329 [Arne Ansper <arne@ats.cyber.ee>]
5331 *) BIO_s_socket() had a broken should_retry() on Windoze.
5332 [Arne Ansper <arne@ats.cyber.ee>]
5334 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
5335 [Arne Ansper <arne@ats.cyber.ee>]
5337 *) Make sure the already existing X509_STORE->depth variable is initialized
5338 in X509_STORE_new(), but document the fact that this variable is still
5339 unused in the certificate verification process.
5340 [Ralf S. Engelschall]
5342 *) Fix the various library and apps files to free up pkeys obtained from
5343 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
5346 *) Fix reference counting in X509_PUBKEY_get(). This makes
5347 demos/maurice/example2.c work, amongst others, probably.
5348 [Steve Henson and Ben Laurie]
5350 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
5351 `openssl' and second, the shortcut symlinks for the `openssl <command>'
5352 are no longer created. This way we have a single and consistent command
5353 line interface `openssl <command>', similar to `cvs <command>'.
5354 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
5356 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
5357 BIT STRING wrapper always have zero unused bits.
5360 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
5363 *) Make the top-level INSTALL documentation easier to understand.
5366 *) Makefiles updated to exit if an error occurs in a sub-directory
5367 make (including if user presses ^C) [Paul Sutton]
5369 *) Make Montgomery context stuff explicit in RSA data structure.
5372 *) Fix build order of pem and err to allow for generated pem.h.
5375 *) Fix renumbering bug in X509_NAME_delete_entry().
5378 *) Enhanced the err-ins.pl script so it makes the error library number
5379 global and can add a library name. This is needed for external ASN1 and
5380 other error libraries.
5383 *) Fixed sk_insert which never worked properly.
5386 *) Fix ASN1 macros so they can handle indefinite length construted
5387 EXPLICIT tags. Some non standard certificates use these: they can now
5391 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
5392 into a single doc/ssleay.txt bundle. This way the information is still
5393 preserved but no longer messes up this directory. Now it's new room for
5394 the new set of documenation files.
5395 [Ralf S. Engelschall]
5397 *) SETs were incorrectly DER encoded. This was a major pain, because they
5398 shared code with SEQUENCEs, which aren't coded the same. This means that
5399 almost everything to do with SETs or SEQUENCEs has either changed name or
5400 number of arguments.
5401 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
5403 *) Fix test data to work with the above.
5406 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
5407 was already fixed by Eric for 0.9.1 it seems.
5408 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
5410 *) Autodetect FreeBSD3.
5413 *) Fix various bugs in Configure. This affects the following platforms:
5417 unixware-2.0-pentium
5421 *) Eliminate generated files from CVS. Reorder tests to regenerate files
5422 before they are needed.
5425 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
5429 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
5431 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
5432 changed SSLeay to OpenSSL in version strings.
5433 [Ralf S. Engelschall]
5435 *) Some fixups to the top-level documents.
5438 *) Fixed the nasty bug where rsaref.h was not found under compile-time
5439 because the symlink to include/ was missing.
5440 [Ralf S. Engelschall]
5442 *) Incorporated the popular no-RSA/DSA-only patches
5443 which allow to compile a RSA-free SSLeay.
5444 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
5446 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
5447 when "ssleay" is still not found.
5448 [Ralf S. Engelschall]
5450 *) Added more platforms to Configure: Cray T3E, HPUX 11,
5451 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
5453 *) Updated the README file.
5454 [Ralf S. Engelschall]
5456 *) Added various .cvsignore files in the CVS repository subdirs
5457 to make a "cvs update" really silent.
5458 [Ralf S. Engelschall]
5460 *) Recompiled the error-definition header files and added
5461 missing symbols to the Win32 linker tables.
5462 [Ralf S. Engelschall]
5464 *) Cleaned up the top-level documents;
5465 o new files: CHANGES and LICENSE
5466 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
5467 o merged COPYRIGHT into LICENSE
5468 o removed obsolete TODO file
5469 o renamed MICROSOFT to INSTALL.W32
5470 [Ralf S. Engelschall]
5472 *) Removed dummy files from the 0.9.1b source tree:
5473 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
5474 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
5475 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
5476 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
5477 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
5478 [Ralf S. Engelschall]
5480 *) Added various platform portability fixes.
5483 *) The Genesis of the OpenSSL rpject:
5484 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
5485 Young and Tim J. Hudson created while they were working for C2Net until
5487 [The OpenSSL Project]
5490 Changes between 0.9.0b and 0.9.1b [not released]
5492 *) Updated a few CA certificates under certs/
5495 *) Changed some BIGNUM api stuff.
5498 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
5499 DGUX x86, Linux Alpha, etc.
5502 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
5503 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
5507 *) Add -strparse option to asn1pars program which parses nested
5509 [Dr Stephen Henson <shenson@bigfoot.com>]
5511 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
5514 *) DSA fix for "ca" program.
5517 *) Added "-genkey" option to "dsaparam" program.
5520 *) Added RIPE MD160 (rmd160) message digest.
5523 *) Added -a (all) option to "ssleay version" command.
5526 *) Added PLATFORM define which is the id given to Configure.
5529 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
5532 *) Extended the ASN.1 parser routines.
5535 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
5538 *) Added a BN_CTX to the BN library.
5541 *) Fixed the weak key values in DES library
5544 *) Changed API in EVP library for cipher aliases.
5547 *) Added support for RC2/64bit cipher.
5550 *) Converted the lhash library to the crypto/mem.c functions.
5553 *) Added more recognized ASN.1 object ids.
5556 *) Added more RSA padding checks for SSL/TLS.
5559 *) Added BIO proxy/filter functionality.
5562 *) Added extra_certs to SSL_CTX which can be used
5563 send extra CA certificates to the client in the CA cert chain sending
5564 process. It can be configured with SSL_CTX_add_extra_chain_cert().
5567 *) Now Fortezza is denied in the authentication phase because
5568 this is key exchange mechanism is not supported by SSLeay at all.
5571 *) Additional PKCS1 checks.
5574 *) Support the string "TLSv1" for all TLS v1 ciphers.
5577 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
5578 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
5581 *) Fixed a few memory leaks.
5584 *) Fixed various code and comment typos.
5587 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
5588 bytes sent in the client random.
