5 Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
7 *) Add a function EC_GROUP_check_discriminant() (defined via
8 EC_METHOD) that verifies that the curve discriminant is non-zero.
10 Add a function EC_GROUP_check() that makes some sanity tests
11 on a EC_GROUP, its generator and order. This includes
12 EC_GROUP_check_discriminant().
13 [Nils Larsch <nla@trustcenter.de>]
15 *) Add ECDSA in new directory crypto/ecdsa/.
17 Add applications 'openssl ecdsaparam' and 'openssl ecdsa'
18 (these are variants of 'openssl dsaparam' and 'openssl dsa').
20 ECDSA support is also included in various other files across the
21 library. Most notably,
22 - 'openssl req' now has a '-newkey ecdsa:file' option;
23 - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
24 - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
25 d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
26 them suitable for ECDSA where domain parameters must be
27 extracted before the specific public key.
28 [Nils Larsch <nla@trustcenter.de>]
30 *) Include some named elliptic curves, and add OIDs from X9.62,
31 SECG, and WAP/WTLS. The curves can be obtained from the new
34 EC_GROUP_new_by_name()
35 Also add a 'nid' field to EC_GROUP objects, which can be accessed
39 [Nils Larsch <nla@trustcenter.de, Bodo Moeller]
41 Changes between 0.9.6 and 0.9.7 [xx XXX 2002]
43 OpenSSL 0.9.6a/0.9.6b/0.9.6c/0.9.6d (bugfix releases, 5 Apr 2001,
44 9 July 2001, 21 Dec 2001 and xx XXX 2002) and OpenSSL 0.9.7 were
45 developed in parallel, based on OpenSSL 0.9.6.
47 Change log entries are tagged as follows:
48 -) applies to 0.9.6a ... 0.9.6d only
49 *) applies to 0.9.6a ... 0.9.6d and 0.9.7
50 +) applies to 0.9.7 only
52 *) Fix DH_generate_parameters() so that it works for 'non-standard'
53 generators, i.e. generators other than 2 and 5. (Previously, the
54 code did not properly initialise the 'add' and 'rem' values to
57 In the new general case, we do not insist that 'generator' is
58 actually a primitive root: This requirement is rather pointless;
59 a generator of the order-q subgroup is just as good, if not
63 *) Map new X509 verification errors to alerts. Discovered and submitted by
64 Tom Wu <tom@arcot.com>.
67 *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
68 returning non-zero before the data has been completely received
69 when using non-blocking I/O.
70 [Bodo Moeller; problem pointed out by John Hughes]
72 *) Some of the ciphers missed the strength entry (SSL_LOW etc).
73 [Ben Laurie, Lutz Jaenicke]
75 +) Add an "init" command to the ENGINE config module and auto initialize
76 ENGINEs. Without any "init" command the ENGINE will be initialized
77 after all ctrl commands have been executed on it. If init=1 the
78 ENGINE is initailized at that point (ctrls before that point are run
79 on the uninitialized ENGINE and after on the initialized one). If
80 init=0 then the ENGINE will not be iniatialized at all.
83 +) Fix the 'app_verify_callback' interface so that the user-defined
84 argument is actually passed to the callback: In the
85 SSL_CTX_set_cert_verify_callback() prototype, the callback
86 declaration has been changed from
89 int (*cb)(X509_STORE_CTX *,void *);
90 in ssl_verify_cert_chain (ssl/ssl_cert.c), the call
91 i=s->ctx->app_verify_callback(&ctx)
93 i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg).
95 To update applications using SSL_CTX_set_cert_verify_callback(),
96 a dummy argument can be added to their callback functions.
97 [D. K. Smetters <smetters@parc.xerox.com>]
99 +) Added the '4758cca' ENGINE to support IBM 4758 cards.
100 [Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe]
102 *) Fix bug in SSL_clear(): bad sessions were not removed (found by
103 Yoram Zahavi <YoramZ@gilian.com>).
106 +) Add and OPENSSL_LOAD_CONF define which will cause
107 OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
108 This allows older applications to transparently support certain
109 OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.
110 Two new functions OPENSSL_add_all_algorithms_noconf() which will never
111 load the config file and OPENSSL_add_all_algorithms_conf() which will
112 always load it have also been added.
115 +) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
116 Adjust NIDs and EVP layer.
117 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
119 +) Config modules support in openssl utility.
121 Most commands now load modules from the config file,
122 though in a few (such as version) this isn't done
123 because it couldn't be used for anything.
125 In the case of ca and req the config file used is
126 the same as the utility itself: that is the -config
127 command line option can be used to specify an
131 +) Move default behaviour from OPENSSL_config(). If appname is NULL
132 use "openssl_conf" if filename is NULL use default openssl config file.
135 +) Add an argument to OPENSSL_config() to allow the use of an alternative
136 config section name. Add a new flag to tolerate a missing config file
137 and move code to CONF_modules_load_file().
140 *) Add information about CygWin 1.3 and on, and preserve proper
141 configuration for the versions before that.
142 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
144 *) Make removal from session cache (SSL_CTX_remove_session()) more robust:
145 check whether we deal with a copy of a session and do not delete from
146 the cache in this case. Problem reported by "Izhar Shoshani Levi"
147 <izhar@checkpoint.com>.
150 *) Do not store session data into the internal session cache, if it
151 is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
152 flag is set). Proposed by Aslam <aslam@funk.com>.
155 +) Support for crypto accelerator cards from Accelerated Encryption
156 Processing, www.aep.ie. (Use engine 'aep')
157 The support was copied from 0.9.6c [engine] and adapted/corrected
158 to work with the new engine framework.
159 [AEP Inc. and Richard Levitte]
161 +) Support for SureWare crypto accelerator cards from Baltimore
162 Technologies. (Use engine 'sureware')
163 The support was copied from 0.9.6c [engine] and adapted
164 to work with the new engine framework.
167 *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
171 +) Have the CHIL engine fork-safe (as defined by nCipher) and actually
172 make the newer ENGINE framework commands for the CHIL engine work.
173 [Toomas Kiisk <vix@cyber.ee> and Richard Levitte]
175 +) Make it possible to produce shared libraries on ReliantUNIX.
176 [Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte]
178 *) Add the configuration target linux-s390x.
179 [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
181 +) Add the configuration target debug-linux-ppro.
182 Make 'openssl rsa' use the general key loading routines
183 implemented in apps.c, and make those routines able to
184 handle the key format FORMAT_NETSCAPE and the variant
186 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
188 *) Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
189 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
191 +) Add -keyform to rsautl, and document -engine.
192 [Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>]
194 +) Change BIO_new_file (crypto/bio/bss_file.c) to use new
195 BIO_R_NO_SUCH_FILE error code rather than the generic
196 ERR_R_SYS_LIB error code if fopen() fails with ENOENT.
201 ERR_peek_last_error_line
202 ERR_peek_last_error_line_data.
206 ERR_peek_error_line_data,
207 but report on the latest error recorded rather than the first one
208 still in the error queue.
209 [Ben Laurie, Bodo Moeller]
211 +) default_algorithms option in ENGINE config module. This allows things
213 default_algorithms = ALL
214 default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS
217 +) Prelminary ENGINE config module.
220 *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
221 ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
222 variable as an indication that a ClientHello message has been
223 received. As the flag value will be lost between multiple
224 invocations of ssl3_accept when using non-blocking I/O, the
225 function may not be aware that a handshake has actually taken
226 place, thus preventing a new session from being added to the
229 To avoid this problem, we now set s->new_session to 2 instead of
230 using a local variable.
231 [Lutz Jaenicke, Bodo Moeller]
233 *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
234 if the SSL_R_LENGTH_MISMATCH error is detected.
235 [Geoff Thorpe, Bodo Moeller]
237 +) New experimental application configuration code.
240 *) New 'shared_ldflag' column in Configure platform table.
243 *) Fix EVP_CIPHER_mode macro.
244 ["Dan S. Camper" <dan@bti.net>]
246 +) Change the AES code to follow the same name structure as all other
247 symmetric ciphers, and behave the same way. Move everything to
248 the directory crypto/aes, thereby obsoleting crypto/rijndael.
249 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
251 *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
252 type, we must throw them away by setting rr->length to 0.
253 [D P Chang <dpc@qualys.com>]
255 -) OpenSSL 0.9.6c released [21 dec 2001]
257 +) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c.
258 [Ben Laurie and Theo de Raadt]
260 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
261 <Dominikus.Scherkl@biodata.com>. (The previous implementation
262 worked incorrectly for those cases where range = 10..._2 and
263 3*range is two bits longer than range.)
266 *) Only add signing time to PKCS7 structures if it is not already
270 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
271 OBJ_ld_ce should be OBJ_id_ce.
272 Also some ip-pda OIDs in crypto/objects/objects.txt were
273 incorrect (cf. RFC 3039).
274 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
276 +) Add option to output public keys in req command.
277 [Massimiliano Pala madwolf@openca.org]
279 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
280 returns early because it has nothing to do.
281 [Andy Schneider <andy.schneider@bjss.co.uk>]
283 *) [In 0.9.6c-engine and 0.9.7 release:]
284 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
285 [Andy Schneider <andy.schneider@bjss.co.uk>]
287 -) [In 0.9.6c-engine release:]
288 Add support for Cryptographic Appliance's keyserver technology.
289 (Use engine 'keyclient')
290 [Cryptographic Appliances and Geoff Thorpe]
292 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
293 is called via tools/c89.sh because arguments have to be
294 rearranged (all '-L' options must appear before the first object
296 [Richard Shapiro <rshapiro@abinitio.com>]
298 +) Use wNAFs in EC_POINTs_mul() for improved efficiency
299 (up to about 10% better than before for P-192 and P-224).
302 -) [In 0.9.6c-engine release:]
303 Add support for Broadcom crypto accelerator cards, backported
305 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
307 -) [In 0.9.6c-engine release:]
308 Add support for SureWare crypto accelerator cards from
309 Baltimore Technologies. (Use engine 'sureware')
310 [Baltimore Technologies and Mark Cox]
312 -) [In 0.9.6c-engine release:]
313 Add support for crypto accelerator cards from Accelerated
314 Encryption Processing, www.aep.ie. (Use engine 'aep')
315 [AEP Inc. and Mark Cox]
317 *) Add a configuration entry for gcc on UnixWare.
318 [Gary Benson <gbenson@redhat.com>]
320 +) New functions/macros
322 SSL_CTX_set_msg_callback(ctx, cb)
323 SSL_CTX_set_msg_callback_arg(ctx, arg)
324 SSL_set_msg_callback(ssl, cb)
325 SSL_set_msg_callback_arg(ssl, arg)
327 to request calling a callback function
329 void cb(int write_p, int version, int content_type,
330 const void *buf, size_t len, SSL *ssl, void *arg)
332 whenever a protocol message has been completely received
333 (write_p == 0) or sent (write_p == 1). Here 'version' is the
334 protocol version according to which the SSL library interprets
335 the current protocol message (SSL2_VERSION, SSL3_VERSION, or
336 TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or
337 the content type as defined in the SSL 3.0/TLS 1.0 protocol
338 specification (change_cipher_spec(20), alert(21), handshake(22)).
339 'buf' and 'len' point to the actual message, 'ssl' to the
340 SSL object, and 'arg' is the application-defined value set by
341 SSL[_CTX]_set_msg_callback_arg().
343 'openssl s_client' and 'openssl s_server' have new '-msg' options
344 to enable a callback that displays all protocol messages.
347 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
348 messages are stored in a single piece (fixed-length part and
349 variable-length part combined) and fix various bugs found on the way.
352 +) Change the shared library support so shared libraries are built as
353 soon as the corresponding static library is finished, and thereby get
354 openssl and the test programs linked against the shared library.
355 This still only happens when the keyword "shard" has been given to
356 the configuration scripts.
358 NOTE: shared library support is still an experimental thing, and
359 backward binary compatibility is still not guaranteed.
360 ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte]
362 +) Add support for Subject Information Access extension.
363 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
365 +) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero
366 additional bytes when new memory had to be allocated, not just
367 when reusing an existing buffer.
370 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
371 instead. BIO_gethostbyname() does not know what timeouts are
372 appropriate, so entries would stay in cache even when they have
374 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
376 +) New command line and configuration option 'utf8' for the req command.
377 This allows field values to be specified as UTF8 strings.
380 +) Add -multi and -mr options to "openssl speed" - giving multiple parallel
381 runs for the former and machine-readable output for the latter.
384 +) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion
385 of the e-mail address in the DN (i.e., it will go into a certificate
386 extension only). The new configuration file option 'email_in_dn = no'
388 [Massimiliano Pala madwolf@openca.org]
390 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
391 faced with a pathologically small ClientHello fragment that does
392 not contain client_version: Instead of aborting with an error,
393 simply choose the highest available protocol version (i.e.,
394 TLS 1.0 unless it is disabled). In practice, ClientHello
395 messages are never sent like this, but this change gives us
396 strictly correct behaviour at least for TLS.
399 +) Change all functions with names starting with des_ to be starting
400 with DES_ instead. Add wrappers that are compatible with libdes,
401 but are named _ossl_old_des_*. Finally, add macros that map the
402 des_* symbols to the corresponding _ossl_old_des_*.
404 All this is done because there are increasing clashes with libdes
405 and other DES libraries that are currently used by other projects.
406 The old libdes interface (including crypt()) is provided if
407 <openssl/des_old.h> is included. For now, this automatically
408 happens in <openssl/des.h> unless OPENSSL_DISABLE_OLD_DES_SUPPORT is
409 defined. Note that crypt() is no longer declared in <openssl/des.h>.
411 NOTE: This is a major break of an old API into a new one. Software
412 authors are encouraged to switch to the DES_ style functions. Some
413 time in the future, des_old.h and the libdes compatibility functions
414 will be completely removed.
417 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
418 never resets s->method to s->ctx->method when called from within
419 one of the SSL handshake functions.
420 [Bodo Moeller; problem pointed out by Niko Baric]
422 +) Test for certificates which contain unsupported critical extensions.
423 If such a certificate is found during a verify operation it is
424 rejected by default: this behaviour can be overridden by either
425 handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
426 by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
427 X509_supported_extension() has also been added which returns 1 if a
428 particular extension is supported.
431 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
432 (sent using the client's version number) if client_version is
433 smaller than the protocol version in use. Also change
434 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
435 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
436 the client will at least see that alert.
439 +) Modify the behaviour of EVP cipher functions in similar way to digests
440 to retain compatibility with existing code.
443 +) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain
444 compatibility with existing code. In particular the 'ctx' parameter does
445 not have to be to be initialized before the call to EVP_DigestInit() and
446 it is tidied up after a call to EVP_DigestFinal(). New function
447 EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
448 EVP_MD_CTX_copy() changed to not require the destination to be
449 initialized valid and new function EVP_MD_CTX_copy_ex() added which
450 requires the destination to be valid.
452 Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
453 EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
456 +) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
457 so that complete 'Handshake' protocol structures are kept in memory
458 instead of overwriting 'msg_type' and 'length' with 'body' data.
461 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
465 +) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
466 [Massimo Santin via Richard Levitte]
468 +) Major restructuring to the underlying ENGINE code. This includes
469 reduction of linker bloat, separation of pure "ENGINE" manipulation
470 (initialisation, etc) from functionality dealing with implementations
471 of specific crypto iterfaces. This change also introduces integrated
472 support for symmetric ciphers and digest implementations - so ENGINEs
473 can now accelerate these by providing EVP_CIPHER and EVP_MD
474 implementations of their own. This is detailed in crypto/engine/README
475 as it couldn't be adequately described here. However, there are a few
476 API changes worth noting - some RSA, DSA, DH, and RAND functions that
477 were changed in the original introduction of ENGINE code have now
478 reverted back - the hooking from this code to ENGINE is now a good
479 deal more passive and at run-time, operations deal directly with
480 RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
481 dereferencing through an ENGINE pointer any more. Also, the ENGINE
482 functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
483 they were not being used by the framework as there is no concept of a
484 BIGNUM_METHOD and they could not be generalised to the new
485 'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
486 ENGINE_cpy() has been removed as it cannot be consistently defined in
490 +) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
493 +) Change mkdef.pl to sort symbols that get the same entry number,
494 and make sure the automatically generated functions ERR_load_*
495 become part of libeay.num as well.
498 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
499 client receives HelloRequest while in a handshake.
500 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
502 +) New function SSL_renegotiate_pending(). This returns true once
503 renegotiation has been requested (either SSL_renegotiate() call
504 or HelloRequest/ClientHello receveived from the peer) and becomes
505 false once a handshake has been completed.
506 (For servers, SSL_renegotiate() followed by SSL_do_handshake()
507 sends a HelloRequest, but does not ensure that a handshake takes
508 place. SSL_renegotiate_pending() is useful for checking if the
509 client has followed the request.)
512 +) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
513 By default, clients may request session resumption even during
514 renegotiation (if session ID contexts permit); with this option,
515 session resumption is possible only in the first handshake.
518 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
519 should end in 'break', not 'goto end' which circuments various
520 cleanups done in state SSL_ST_OK. But session related stuff
521 must be disabled for SSL_ST_OK in the case that we just sent a
524 Also avoid some overhead by not calling ssl_init_wbio_buffer()
525 before just sending a HelloRequest.
526 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
528 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
529 reveal whether illegal block cipher padding was found or a MAC
530 verification error occured. (Neither SSLerr() codes nor alerts
531 are directly visible to potential attackers, but the information
532 may leak via logfiles.)
534 Similar changes are not required for the SSL 2.0 implementation
535 because the number of padding bytes is sent in clear for SSL 2.0,
536 and the extra bytes are just ignored. However ssl/s2_pkt.c
537 failed to verify that the purported number of padding bytes is in
541 +) Add some demos for certificate and certificate request creation.
544 +) Make maximum certificate chain size accepted from the peer application
545 settable (SSL*_get/set_max_cert_list()), as proposed by
546 "Douglas E. Engert" <deengert@anl.gov>.
549 +) Add support for shared libraries for Unixware-7
550 (Boyd Lynn Gerber <gerberb@zenez.com>).
553 *) Add OpenUNIX-8 support including shared libraries
554 (Boyd Lynn Gerber <gerberb@zenez.com>).
557 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
558 'wristwatch attack' using huge encoding parameters (cf.
559 James H. Manger's CRYPTO 2001 paper). Note that the
560 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
561 encoding parameters and hence was not vulnerable.
564 +) Add a "destroy" handler to ENGINEs that allows structural cleanup to
565 be done prior to destruction. Use this to unload error strings from
566 ENGINEs that load their own error strings. NB: This adds two new API
567 functions to "get" and "set" this destroy handler in an ENGINE.
570 +) Alter all existing ENGINE implementations (except "openssl" and
571 "openbsd") to dynamically instantiate their own error strings. This
572 makes them more flexible to be built both as statically-linked ENGINEs
573 and self-contained shared-libraries loadable via the "dynamic" ENGINE.
574 Also, add stub code to each that makes building them as self-contained
575 shared-libraries easier (see README.ENGINE).
578 +) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
579 implementations into applications that are completely implemented in
580 self-contained shared-libraries. The "dynamic" ENGINE exposes control
581 commands that can be used to configure what shared-library to load and
582 to control aspects of the way it is handled. Also, made an update to
583 the README.ENGINE file that brings its information up-to-date and
584 provides some information and instructions on the "dynamic" ENGINE
585 (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
589 [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
591 +) Make it possible to unload ranges of ERR strings with a new
592 "ERR_unload_strings" function.
595 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
596 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
597 followed by modular reduction.
598 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
600 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
601 equivalent based on BN_pseudo_rand() instead of BN_rand().
604 +) Add a copy() function to EVP_MD.
607 +) Make EVP_MD routines take a context pointer instead of just the
608 md_data void pointer.
611 +) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
612 that the digest can only process a single chunk of data
613 (typically because it is provided by a piece of
614 hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
615 is only going to provide a single chunk of data, and hence the
616 framework needn't accumulate the data for oneshot drivers.
619 +) As with "ERR", make it possible to replace the underlying "ex_data"
620 functions. This change also alters the storage and management of global
621 ex_data state - it's now all inside ex_data.c and all "class" code (eg.
622 RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
623 index counters. The API functions that use this state have been changed
624 to take a "class_index" rather than pointers to the class's local STACK
625 and counter, and there is now an API function to dynamically create new
626 classes. This centralisation allows us to (a) plug a lot of the
627 thread-safety problems that existed, and (b) makes it possible to clean
628 up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
629 such data would previously have always leaked in application code and
630 workarounds were in place to make the memory debugging turn a blind eye
631 to it. Application code that doesn't use this new function will still
632 leak as before, but their memory debugging output will announce it now
633 rather than letting it slide.
635 Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
636 induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
637 has a return value to indicate success or failure.
640 +) Make it possible to replace the underlying "ERR" functions such that the
641 global state (2 LHASH tables and 2 locks) is only used by the "default"
642 implementation. This change also adds two functions to "get" and "set"
643 the implementation prior to it being automatically set the first time
644 any other ERR function takes place. Ie. an application can call "get",
645 pass the return value to a module it has just loaded, and that module
646 can call its own "set" function using that value. This means the
647 module's "ERR" operations will use (and modify) the error state in the
648 application and not in its own statically linked copy of OpenSSL code.
651 +) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
652 reference counts. This performs normal REF_PRINT/REF_CHECK macros on
653 the operation, and provides a more encapsulated way for external code
654 (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
655 to use these functions rather than manually incrementing the counts.
657 Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
660 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
661 This function was broken, as the check for a new client hello message
662 to handle SGC did not allow these large messages.
663 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
666 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
669 +) Add EVP test program.
672 +) Add symmetric cipher support to ENGINE. Expect the API to change!
675 +) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
676 X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
677 X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
678 These allow a CRL to be built without having to access X509_CRL fields
679 directly. Modify 'ca' application to use new functions.
682 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
683 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
686 *) Rework the configuration and shared library support for Tru64 Unix.
687 The configuration part makes use of modern compiler features and
688 still retains old compiler behavior for those that run older versions
689 of the OS. The shared library support part includes a variant that
690 uses the RPATH feature, and is available through the special
691 configuration target "alpha-cc-rpath", which will never be selected
693 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
695 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
696 with the same message size as in ssl3_get_certificate_request().
697 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
698 messages might inadvertently be reject as too long.
699 [Petr Lampa <lampa@fee.vutbr.cz>]
701 +) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
702 bug workarounds. Rollback attack detection is a security feature.
703 The problem will only arise on OpenSSL servers when TLSv1 is not
704 available (sslv3_server_method() or SSL_OP_NO_TLSv1).
705 Software authors not wanting to support TLSv1 will have special reasons
706 for their choice and can explicitly enable this option.
707 [Bodo Moeller, Lutz Jaenicke]
709 +) Rationalise EVP so it can be extended: don't include a union of
710 cipher/digest structures, add init/cleanup functions. This also reduces
711 the number of header dependencies.
714 +) Make DES key schedule conform to the usual scheme, as well as
715 correcting its structure. This means that calls to DES functions
716 now have to pass a pointer to a des_key_schedule instead of a
717 plain des_key_schedule (which was actually always a pointer
721 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
724 *) Modified SSL library such that the verify_callback that has been set
725 specificly for an SSL object with SSL_set_verify() is actually being
726 used. Before the change, a verify_callback set with this function was
727 ignored and the verify_callback() set in the SSL_CTX at the time of
728 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
729 to allow the necessary settings.
732 +) Initial reduction of linker bloat: the use of some functions, such as
733 PEM causes large amounts of unused functions to be linked in due to
734 poor organisation. For example pem_all.c contains every PEM function
735 which has a knock on effect of linking in large amounts of (unused)
736 ASN1 code. Grouping together similar functions and splitting unrelated
737 functions prevents this.
740 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
741 explicitly to NULL, as at least on Solaris 8 this seems not always to be
742 done automatically (in contradiction to the requirements of the C
743 standard). This made problems when used from OpenSSH.
746 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
747 dh->length and always used
749 BN_rand_range(priv_key, dh->p).
751 BN_rand_range() is not necessary for Diffie-Hellman, and this
752 specific range makes Diffie-Hellman unnecessarily inefficient if
753 dh->length (recommended exponent length) is much smaller than the
754 length of dh->p. We could use BN_rand_range() if the order of
755 the subgroup was stored in the DH structure, but we only have
760 BN_rand(priv_key, l, ...)
762 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
768 RSA_eay_public_encrypt
769 RSA_eay_private_decrypt
770 RSA_eay_private_encrypt (signing)
771 RSA_eay_public_decrypt (signature verification)
773 (default implementations for RSA_public_encrypt,
774 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
775 always reject numbers >= n.
778 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
779 to synchronize access to 'locking_thread'. This is necessary on
780 systems where access to 'locking_thread' (an 'unsigned long'
781 variable) is not atomic.
784 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
785 *before* setting the 'crypto_lock_rand' flag. The previous code had
786 a race condition if 0 is a valid thread ID.
787 [Travis Vitek <vitek@roguewave.com>]
789 +) Cleanup of EVP macros.
792 +) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
796 +) Add initial OCSP responder support to ocsp application. The
797 revocation information is handled using the text based index
798 use by the ca application. The responder can either handle
799 requests generated internally, supplied in files (for example
800 via a CGI script) or using an internal minimal server.
803 +) Add configuration choices to get zlib compression for TLS.
806 +) Changes to Kerberos SSL for RFC 2712 compliance:
807 1. Implemented real KerberosWrapper, instead of just using
808 KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
809 2. Implemented optional authenticator field of KerberosWrapper.
811 Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
812 and authenticator structs; see crypto/krb5/.
814 Generalized Kerberos calls to support multiple Kerberos libraries.
815 [Vern Staats <staatsvr@asc.hpc.mil>,
816 Jeffrey Altman <jaltman@columbia.edu>
819 +) Cause 'openssl speed' to use fully hard-coded DSA keys as it
820 already does with RSA. testdsa.h now has 'priv_key/pub_key'
821 values for each of the key sizes rather than having just
822 parameters (and 'speed' generating keys each time).
825 *) Add support for shared libraries under Irix.
826 [Albert Chin-A-Young <china@thewrittenword.com>]
828 *) Add configuration option to build on Linux on both big-endian and
830 [Ralf Baechle <ralf@uni-koblenz.de>]
832 *) Add the possibility to create shared libraries on HP-UX.
835 -) OpenSSL 0.9.6b released [9 July 2001]
837 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
838 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
839 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
840 PRNG state recovery was possible based on the output of
841 one PRNG request appropriately sized to gain knowledge on
842 'md' followed by enough consecutive 1-byte PRNG requests
843 to traverse all of 'state'.
845 1. When updating 'md_local' (the current thread's copy of 'md')
846 during PRNG output generation, hash all of the previous
847 'md_local' value, not just the half used for PRNG output.
849 2. Make the number of bytes from 'state' included into the hash
850 independent from the number of PRNG bytes requested.
852 The first measure alone would be sufficient to avoid
853 Markku-Juhani's attack. (Actually it had never occurred
854 to me that the half of 'md_local' used for chaining was the
855 half from which PRNG output bytes were taken -- I had always
856 assumed that the secret half would be used.) The second
857 measure makes sure that additional data from 'state' is never
858 mixed into 'md_local' in small portions; this heuristically
859 further strengthens the PRNG.
862 +) Speed up EVP routines.

880 *) Fix crypto/bn/asm/mips3.s.
883 *) When only the key is given to "enc", the IV is undefined. Print out
884 an error message in this case.
887 +) Added the OS2-EMX target.
888 ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
890 +) Rewrite apps to use NCONF routines instead of the old CONF. New functions
891 to support NCONF routines in extension code. New function CONF_set_nconf()
892 to allow functions which take an NCONF to also handle the old LHASH
893 structure: this means that the old CONF compatible routines can be
894 retained (in particular wrt extensions) without having to duplicate the
895 code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
898 *) Handle special case when X509_NAME is empty in X509 printing routines.
901 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
902 positive and less than q.
905 +) Enhance the general user interface with mechanisms for inner control
906 and with possibilities to have yes/no kind of prompts.
909 +) Change all calls to low level digest routines in the library and
910 applications to use EVP. Add missing calls to HMAC_cleanup() and
911 don't assume HMAC_CTX can be copied using memcpy().
912 [Verdon Walker <VWalker@novell.com>, Steve Henson]
914 +) Add the possibility to control engines through control names but with
915 arbitrary arguments instead of just a string.
916 Change the key loaders to take a UI_METHOD instead of a callback
917 function pointer. NOTE: this breaks binary compatibility with earlier
918 versions of OpenSSL [engine].
919 Adapt the nCipher code for these new conditions and add a card insertion
923 +) Enhance the general user interface with mechanisms to better support
924 dialog box interfaces, application-defined prompts, the possibility
925 to use defaults (for example default passwords from somewhere else)
926 and interrupts/cancellations.
929 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
930 used: it isn't thread safe and the add_lock_callback should handle
932 [Paul Rose <Paul.Rose@bridge.com>]
934 *) Verify that incoming data obeys the block size in
935 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
938 +) Tidy up PKCS#12 attribute handling. Add support for the CSP name
939 attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
943 [Ulf Möller, Bodo Möller]
945 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
946 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
947 when fixing the server behaviour for backwards-compatible 'client
948 hello' messages. (Note that the attack is impractical against
949 SSL 3.0 and TLS 1.0 anyway because length and version checking
950 means that the probability of guessing a valid ciphertext is
951 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
954 Before 0.9.5, the countermeasure (hide the error by generating a
955 random 'decryption result') did not work properly because
956 ERR_clear_error() was missing, meaning that SSL_get_error() would
957 detect the supposedly ignored error.
959 Both problems are now fixed.
962 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
963 (previously it was 1024).
966 +) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
967 tidy up some unnecessarily weird code in 'sk_new()').
968 [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
970 +) Change the key loading routines for ENGINEs to use the same kind
971 callback (pem_password_cb) as all other routines that need this
975 *) Fix for compatibility mode trust settings: ignore trust settings
976 unless some valid trust or reject settings are present.
979 *) Fix for blowfish EVP: its a variable length cipher.
982 +) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
983 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
984 than this minimum value is recommended.
987 +) New random seeder for OpenVMS, using the system process statistics
988 that are easily reachable.
991 +) Windows apparently can't transparently handle global
992 variables defined in DLLs. Initialisations such as:
994 const ASN1_ITEM *it = &ASN1_INTEGER_it;
996 wont compile. This is used by the any applications that need to
997 declare their own ASN1 modules. This was fixed by adding the option
998 EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
999 needed for static libraries under Win32.
1002 +) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
1003 setting of purpose and trust fields. New X509_STORE trust and
1004 purpose functions and tidy up setting in other SSL functions.
1007 +) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
1008 structure. These are inherited by X509_STORE_CTX when it is
1009 initialised. This allows various defaults to be set in the
1010 X509_STORE structure (such as flags for CRL checking and custom
1011 purpose or trust settings) for functions which only use X509_STORE_CTX
1012 internally such as S/MIME.
1014 Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
1015 trust settings if they are not set in X509_STORE. This allows X509_STORE
1016 purposes and trust (in S/MIME for example) to override any set by default.
1018 Add command line options for CRL checking to smime, s_client and s_server
1022 +) Initial CRL based revocation checking. If the CRL checking flag(s)
1023 are set then the CRL is looked up in the X509_STORE structure and
1024 its validity and signature checked, then if the certificate is found
1025 in the CRL the verify fails with a revoked error.
1027 Various new CRL related callbacks added to X509_STORE_CTX structure.
1029 Command line options added to 'verify' application to support this.
1031 This needs some additional work, such as being able to handle multiple
1032 CRLs with different times, extension based lookup (rather than just
1033 by subject name) and ultimately more complete V2 CRL extension
1037 +) Add a general user interface API (crypto/ui/). This is designed
1038 to replace things like des_read_password and friends (backward
1039 compatibility functions using this new API are provided).
1040 The purpose is to remove prompting functions from the DES code
1041 section as well as provide for prompting through dialog boxes in
1042 a window system and the like.
1045 *) Fix various bugs related to DSA S/MIME verification. Handle missing
1046 parameters in DSA public key structures and return an error in the
1047 DSA routines if parameters are absent.
1050 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
1051 in the current directory if neither $RANDFILE nor $HOME was set.
1052 RAND_file_name() in 0.9.6a returned NULL in this case. This has
1053 caused some confusion to Windows users who haven't defined $HOME.
1054 Thus RAND_file_name() is changed again: e_os.h can define a
1055 DEFAULT_HOME, which will be used if $HOME is not set.
1056 For Windows, we use "C:"; on other platforms, we still require
1057 environment variables.
1059 +) Add "ex_data" support to ENGINE so implementations can add state at a
1060 per-structure level rather than having to store it globally.
1063 +) Make it possible for ENGINE structures to be copied when retrieved by
1064 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
1065 This causes the "original" ENGINE structure to act like a template,
1066 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
1067 operational state can be localised to each ENGINE structure, despite the
1068 fact they all share the same "methods". New ENGINE structures returned in
1069 this case have no functional references and the return value is the single
1070 structural reference. This matches the single structural reference returned
1071 by ENGINE_by_id() normally, when it is incremented on the pre-existing
1075 +) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
1076 needs to match any other type at all we need to manually clear the
1080 +) Changes to the "openssl engine" utility to include;
1081 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
1082 about an ENGINE's available control commands.
1083 - executing control commands from command line arguments using the
1084 '-pre' and '-post' switches. '-post' is only used if '-t' is
1085 specified and the ENGINE is successfully initialised. The syntax for
1086 the individual commands are colon-separated, for example;
1087 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
1090 +) New dynamic control command support for ENGINEs. ENGINEs can now
1091 declare their own commands (numbers), names (strings), descriptions,
1092 and input types for run-time discovery by calling applications. A
1093 subset of these commands are implicitly classed as "executable"
1094 depending on their input type, and only these can be invoked through
1095 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
1096 can be based on user input, config files, etc). The distinction is
1097 that "executable" commands cannot return anything other than a boolean
1098 result and can only support numeric or string input, whereas some
1099 discoverable commands may only be for direct use through
1100 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
1101 pointers, or other custom uses. The "executable" commands are to
1102 support parameterisations of ENGINE behaviour that can be
1103 unambiguously defined by ENGINEs and used consistently across any
1104 OpenSSL-based application. Commands have been added to all the
1105 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
1106 control over shared-library paths without source code alterations.
1109 +) Changed all ENGINE implementations to dynamically allocate their
1110 ENGINEs rather than declaring them statically. Apart from this being
1111 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
1112 this also allows the implementations to compile without using the
1113 internal engine_int.h header.
1116 +) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
1117 'const' value. Any code that should be able to modify a RAND_METHOD
1118 should already have non-const pointers to it (ie. they should only
1119 modify their own ones).
1122 +) Made a variety of little tweaks to the ENGINE code.
1123 - "atalla" and "ubsec" string definitions were moved from header files
1124 to C code. "nuron" string definitions were placed in variables
1125 rather than hard-coded - allowing parameterisation of these values
1126 later on via ctrl() commands.
1127 - Removed unused "#if 0"'d code.
1128 - Fixed engine list iteration code so it uses ENGINE_free() to release
1129 structural references.
1130 - Constified the RAND_METHOD element of ENGINE structures.
1131 - Constified various get/set functions as appropriate and added
1132 missing functions (including a catch-all ENGINE_cpy that duplicates
1133 all ENGINE values onto a new ENGINE except reference counts/state).
1134 - Removed NULL parameter checks in get/set functions. Setting a method
1135 or function to NULL is a way of cancelling out a previously set
1136 value. Passing a NULL ENGINE parameter is just plain stupid anyway
1137 and doesn't justify the extra error symbols and code.
1138 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
1139 flags from engine_int.h to engine.h.
1140 - Changed prototypes for ENGINE handler functions (init(), finish(),
1141 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
1144 *) Move 'if (!initialized) RAND_poll()' into regions protected by
1145 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
1146 having multiple threads call RAND_poll() concurrently.
1149 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
1150 combination of a flag and a thread ID variable.
1151 Otherwise while one thread is in ssleay_rand_bytes (which sets the
1152 flag), *other* threads can enter ssleay_add_bytes without obeying
1153 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
1154 that they do not hold after the first thread unsets add_do_not_lock).
1157 +) Implement binary inversion algorithm for BN_mod_inverse in addition
1158 to the algorithm using long division. The binary algorithm can be
1159 used only if the modulus is odd. On 32-bit systems, it is faster
1160 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
1161 roughly 5-15% for 256-bit moduli), so we use it only for moduli
1162 up to 450 bits. In 64-bit environments, the binary algorithm
1163 appears to be advantageous for much longer moduli; here we use it
1164 for moduli up to 2048 bits.
1167 *) Change bctest again: '-x' expressions are not available in all
1171 -) OpenSSL 0.9.6a released [5 Apr 2001]
1173 *) Fix a couple of memory leaks in PKCS7_dataDecode()
1174 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
1176 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
1177 the default extension for executables, if any. Also, make the perl
1178 scripts that use symlink() to test if it really exists and use "cp"
1179 if it doesn't. All this made OpenSSL compilable and installable in
1183 +) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
1184 could not support the combine flag in choice fields.
1187 -) Fix for asn1_GetSequence() for indefinite length constructed data.
1188 If SEQUENCE is length is indefinite just set c->slen to the total
1189 amount of data available.
1190 [Steve Henson, reported by shige@FreeBSD.org]
1191 [This change does not apply to 0.9.7.]
1193 *) Change bctest to avoid here-documents inside command substitution
1194 (workaround for FreeBSD /bin/sh bug).
1195 For compatibility with Ultrix, avoid shell functions (introduced
1196 in the bctest version that searches along $PATH).
1199 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
1200 with des_encrypt() defined on some operating systems, like Solaris
1204 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
1205 On the Importance of Eliminating Errors in Cryptographic
1206 Computations, J. Cryptology 14 (2001) 2, 101-119,
1207 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
1210 *) MIPS assembler BIGNUM division bug fix.
1213 *) Disabled incorrect Alpha assembler code.
1216 -) Fix PKCS#7 decode routines so they correctly update the length
1217 after reading an EOC for the EXPLICIT tag.
1219 [This change does not apply to 0.9.7.]
1221 *) Fix bug in PKCS#12 key generation routines. This was triggered
1222 if a 3DES key was generated with a 0 initial byte. Include
1223 PKCS12_BROKEN_KEYGEN compilation option to retain the old
1224 (but broken) behaviour.
1227 *) Enhance bctest to search for a working bc along $PATH and print
1229 [Tim Rice <tim@multitalents.net> via Richard Levitte]
1231 +) Add a 'copy_extensions' option to the 'ca' utility. This copies
1232 extensions from a certificate request to the certificate.
1235 +) Allow multiple 'certopt' and 'nameopt' options to be separated
1236 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
1237 file: this allows the display of the certificate about to be
1238 signed to be customised, to allow certain fields to be included
1239 or excluded and extension details. The old system didn't display
1240 multicharacter strings properly, omitted fields not in the policy
1241 and couldn't display additional details such as extensions.
1244 *) Fix memory leaks in err.c: free err_data string if necessary;
1245 don't write to the wrong index in ERR_set_error_data.
1248 +) Function EC_POINTs_mul for multiple scalar multiplication
1249 of an arbitrary number of elliptic curve points
1250 \sum scalars[i]*points[i],
1251 optionally including the generator defined for the EC_GROUP:
1252 scalar*generator + \sum scalars[i]*points[i].
1254 EC_POINT_mul is a simple wrapper function for the typical case
1255 that the point list has just one item (besides the optional
1259 +) First EC_METHODs for curves over GF(p):
1261 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
1262 operations and provides various method functions that can also
1263 operate with faster implementations of modular arithmetic.
1265 EC_GFp_mont_method() reuses most functions that are part of
1266 EC_GFp_simple_method, but uses Montgomery arithmetic.
1268 [Bodo Moeller; point addition and point doubling
1269 implementation directly derived from source code provided by
1270 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
1272 +) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
1273 crypto/ec/ec_lib.c):
1275 Curves are EC_GROUP objects (with an optional group generator)
1276 based on EC_METHODs that are built into the library.
1278 Points are EC_POINT objects based on EC_GROUP objects.
1280 Most of the framework would be able to handle curves over arbitrary
1281 finite fields, but as there are no obvious types for fields other
1282 than GF(p), some functions are limited to that for now.
1285 +) Add the -HTTP option to s_server. It is similar to -WWW, but requires
1286 that the file contains a complete HTTP response.
1289 +) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
1290 change the def and num file printf format specifier from "%-40sXXX"
1291 to "%-39s XXX". The latter will always guarantee a space after the
1292 field while the former will cause them to run together if the field
1293 is 40 of more characters long.
1296 +) Constify the cipher and digest 'method' functions and structures
1297 and modify related functions to take constant EVP_MD and EVP_CIPHER
1301 *) Implement ssl23_peek (analogous to ssl23_read), which previously
1305 *) Replace rdtsc with _emit statements for VC++ version 5.
1306 [Jeremy Cooper <jeremy@baymoo.org>]
1308 +) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
1309 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
1312 +) Modify EVP_Digest*() routines so they now return values. Although the
1313 internal software routines can never fail additional hardware versions
1317 +) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
1319 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
1320 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
1323 ERR_R_NESTED_ASN1_ERROR
1325 ERR_R_MISSING_ASN1_EOS
1326 were 4 .. 9, conflicting with
1327 ERR_LIB_RSA (= ERR_R_RSA_LIB)
1329 ERR_LIB_PEM (= ERR_R_PEM_LIB).
1330 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
1332 Add new error code 'ERR_R_INTERNAL_ERROR'.
1335 +) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
1339 +) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
1340 sets the subject name for a new request or supersedes the
1341 subject name in a given request. Formats that can be parsed are
1342 'CN=Some Name, OU=myOU, C=IT'
1344 'CN=Some Name/OU=myOU/C=IT'.
1346 Add options '-batch' and '-verbose' to 'openssl req'.
1347 [Massimiliano Pala <madwolf@hackmasters.net>]
1349 *) Make it possible to reuse SSLv2 sessions.
1352 +) Introduce the possibility to access global variables through
1353 functions on platform were that's the best way to handle exporting
1354 global variables in shared libraries. To enable this functionality,
1355 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
1356 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
1357 is normally done by Configure or something similar).
1359 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
1360 in the source file (foo.c) like this:
1362 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
1363 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
1365 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
1366 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
1368 OPENSSL_DECLARE_GLOBAL(int,foo);
1369 #define foo OPENSSL_GLOBAL_REF(foo)
1370 OPENSSL_DECLARE_GLOBAL(double,bar);
1371 #define bar OPENSSL_GLOBAL_REF(bar)
1373 The #defines are very important, and therefore so is including the
1374 header file everywhere where the defined globals are used.
1376 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
1377 of ASN.1 items, but that structure is a bit different.
1379 The largest change is in util/mkdef.pl which has been enhanced with
1380 better and easier to understand logic to choose which symbols should
1381 go into the Windows .def files as well as a number of fixes and code
1382 cleanup (among others, algorithm keywords are now sorted
1383 lexicographically to avoid constant rewrites).
1386 *) In copy_email() check for >= 0 as a return value for
1387 X509_NAME_get_index_by_NID() since 0 is a valid index.
1388 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
1390 +) In BN_div() keep a copy of the sign of 'num' before writing the
1391 result to 'rm' because if rm==num the value will be overwritten
1392 and produce the wrong result if 'num' is negative: this caused
1393 problems with BN_mod() and BN_nnmod().
1396 +) Function OCSP_request_verify(). This checks the signature on an
1397 OCSP request and verifies the signer certificate. The signer
1398 certificate is just checked for a generic purpose and OCSP request
1402 +) Add OCSP_check_validity() function to check the validity of OCSP
1403 responses. OCSP responses are prepared in real time and may only
1404 be a few seconds old. Simply checking that the current time lies
1405 between thisUpdate and nextUpdate max reject otherwise valid responses
1406 caused by either OCSP responder or client clock inaccuracy. Instead
1407 we allow thisUpdate and nextUpdate to fall within a certain period of
1408 the current time. The age of the response can also optionally be
1409 checked. Two new options -validity_period and -status_age added to
1413 +) If signature or public key algorithm is unrecognized print out its
1414 OID rather that just UNKNOWN.
1417 *) Avoid coredump with unsupported or invalid public keys by checking if
1418 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
1419 PKCS7_verify() fails with non detached data.
1422 +) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
1423 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
1424 ID to be generated from the issuer certificate alone which can then be
1425 passed to OCSP_id_issuer_cmp().
1428 +) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
1429 ASN1 modules to export functions returning ASN1_ITEM pointers
1430 instead of the ASN1_ITEM structures themselves. This adds several
1431 new macros which allow the underlying ASN1 function/structure to
1432 be accessed transparently. As a result code should not use ASN1_ITEM
1433 references directly (such as &X509_it) but instead use the relevant
1434 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
1435 use of the new ASN1 code on platforms where exporting structures
1436 is problematical (for example in shared libraries) but exporting
1437 functions returning pointers to structures is not.
1440 +) Add support for overriding the generation of SSL/TLS session IDs.
1441 These callbacks can be registered either in an SSL_CTX or per SSL.
1442 The purpose of this is to allow applications to control, if they wish,
1443 the arbitrary values chosen for use as session IDs, particularly as it
1444 can be useful for session caching in multiple-server environments. A
1445 command-line switch for testing this (and any client code that wishes
1446 to use such a feature) has been added to "s_server".
1447 [Geoff Thorpe, Lutz Jaenicke]
1449 +) Modify mkdef.pl to recognise and parse preprocessor conditionals
1450 of the form '#if defined(...) || defined(...) || ...' and
1451 '#if !defined(...) && !defined(...) && ...'. This also avoids
1452 the growing number of special cases it was previously handling.
1455 *) Don't use getenv in library functions when run as setuid/setgid.
1456 New function OPENSSL_issetugid().
1459 +) Make all configuration macros available for application by making
1460 sure they are available in opensslconf.h, by giving them names starting
1461 with "OPENSSL_" to avoid conflicts with other packages and by making
1462 sure e_os2.h will cover all platform-specific cases together with
1464 Additionally, it is now possible to define configuration/platform-
1465 specific names (called "system identities"). In the C code, these
1466 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
1467 macro with the name beginning with "OPENSSL_SYS_", which is determined
1468 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
1472 +) New option -set_serial to 'req' and 'x509' this allows the serial
1473 number to use to be specified on the command line. Previously self
1474 signed certificates were hard coded with serial number 0 and the
1475 CA options of 'x509' had to use a serial number in a file which was
1479 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
1480 due to incorrect handling of multi-threading:
1482 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
1484 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
1486 3. Count how many times MemCheck_off() has been called so that
1487 nested use can be treated correctly. This also avoids
1488 inband-signalling in the previous code (which relied on the
1489 assumption that thread ID 0 is impossible).
1492 +) New options to 'ca' utility to support V2 CRL entry extensions.
1493 Currently CRL reason, invalidity date and hold instruction are
1494 supported. Add new CRL extensions to V3 code and some new objects.
1497 *) Add "-rand" option also to s_client and s_server.
1500 +) New function EVP_CIPHER_CTX_set_padding() this is used to
1501 disable standard block padding (aka PKCS#5 padding) in the EVP
1502 API, which was previously mandatory. This means that the data is
1503 not padded in any way and so the total length much be a multiple
1504 of the block size, otherwise an error occurs.
1507 +) Initial (incomplete) OCSP SSL support.
1510 *) Fix CPU detection on Irix 6.x.
1511 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
1512 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
1514 +) New function OCSP_parse_url(). This splits up a URL into its host,
1515 port and path components: primarily to parse OCSP URLs. New -url
1516 option to ocsp utility.
1519 +) New nonce behavior. The return value of OCSP_check_nonce() now
1520 reflects the various checks performed. Applications can decide
1521 whether to tolerate certain situations such as an absent nonce
1522 in a response when one was present in a request: the ocsp application
1523 just prints out a warning. New function OCSP_add1_basic_nonce()
1524 this is to allow responders to include a nonce in a response even if
1525 the request is nonce-less.
1528 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
1531 [This change does not apply to 0.9.7.]
1533 *) Use the cached encoding of an X509_NAME structure rather than
1534 copying it. This is apparently the reason for the libsafe "errors"
1535 but the code is actually correct.
1538 +) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
1539 skipped when using openssl x509 multiple times on a single input file,
1540 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
1543 +) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
1544 set string type: to handle setting ASN1_TIME structures. Fix ca
1545 utility to correctly initialize revocation date of CRLs.
1548 +) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
1549 the clients preferred ciphersuites and rather use its own preferences.
1550 Should help to work around M$ SGC (Server Gated Cryptography) bug in
1551 Internet Explorer by ensuring unchanged hash method during stepup.
1552 (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
1555 +) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
1556 to aes and add a new 'exist' option to print out symbols that don't
1560 +) Additional options to ocsp utility to allow flags to be set and
1561 additional certificates supplied.
1564 +) Add the option -VAfile to 'openssl ocsp', so the user can give the
1565 OCSP client a number of certificate to only verify the response
1569 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
1570 Bleichenbacher's DSA attack.
1571 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
1572 to be set and top=0 forces the highest bit to be set; top=-1 is new
1573 and leaves the highest bit random.
1574 [Ulf Moeller, Bodo Moeller]
1576 +) Update Rijndael code to version 3.0 and change EVP AES ciphers to
1577 handle the new API. Currently only ECB, CBC modes supported. Add new
1578 AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
1579 for TLS" draft-ietf-tls-ciphersuite-03.txt.
1580 [Ben Laurie, Steve Henson]
1582 *) In the NCONF_...-based implementations for CONF_... queries
1583 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
1584 a temporary CONF structure with the data component set to NULL
1585 (which gives segmentation faults in lh_retrieve).
1586 Instead, use NULL for the CONF pointer in CONF_get_string and
1587 CONF_get_number (which may use environment variables) and directly
1588 return NULL from CONF_get_section.
1591 *) Fix potential buffer overrun for EBCDIC.
1594 +) New function OCSP_copy_nonce() to copy nonce value (if present) from
1595 request to response.
1598 +) Functions for OCSP responders. OCSP_request_onereq_count(),
1599 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
1600 extract information from a certificate request. OCSP_response_create()
1601 creates a response and optionally adds a basic response structure.
1602 OCSP_basic_add1_status() adds a complete single response to a basic
1603 response and returns the OCSP_SINGLERESP structure just added (to allow
1604 extensions to be included for example). OCSP_basic_add1_cert() adds a
1605 certificate to a basic response and OCSP_basic_sign() signs a basic
1606 response with various flags. New helper functions ASN1_TIME_check()
1607 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
1608 (converts ASN1_TIME to GeneralizedTime).
1611 +) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
1612 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
1613 structure from a certificate. X509_pubkey_digest() digests the public_key
1614 contents: this is used in various key identifiers.
1617 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
1618 keyUsage if basicConstraints absent for a CA.
1621 *) Make SMIME_write_PKCS7() write mail header values with a format that
1622 is more generally accepted (no spaces before the semicolon), since
1623 some programs can't parse those values properly otherwise. Also make
1624 sure BIO's that break lines after each write do not create invalid
1628 +) Make sk_sort() tolerate a NULL argument.
1629 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
1631 +) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
1632 passed by the function are trusted implicitly. If any of them signed the
1633 response then it is assumed to be valid and is not verified.
1636 -) Make the CRL encoding routines work with empty SEQUENCE OF. The
1637 macros previously used would not encode an empty SEQUENCE OF
1638 and break the signature.
1640 [This change does not apply to 0.9.7.]
1642 *) Zero the premaster secret after deriving the master secret in
1646 +) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
1647 to data. This was previously part of the PKCS7 ASN1 code. This
1648 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
1649 [Steve Henson, reported by Kenneth R. Robinette
1650 <support@securenetterm.com>]
1652 +) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
1653 routines: without these tracing memory leaks is very painful.
1654 Fix leaks in PKCS12 and PKCS7 routines.
1657 *) Add some EVP_add_digest_alias registrations (as found in
1658 OpenSSL_add_all_digests()) to SSL_library_init()
1659 aka OpenSSL_add_ssl_algorithms(). This provides improved
1660 compatibility with peers using X.509 certificates
1661 with unconventional AlgorithmIdentifier OIDs.
1664 *) Fix for Irix with NO_ASM.
1665 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
1667 *) ./config script fixes.
1668 [Ulf Moeller, Richard Levitte]
1670 +) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
1671 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
1672 effectively meant GeneralizedTime would never be used. Now it
1673 is initialised to -1 but X509_time_adj() now has to check the value
1674 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
1675 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
1676 [Steve Henson, reported by Kenneth R. Robinette
1677 <support@securenetterm.com>]
1679 +) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
1680 result in a zero length in the ASN1_INTEGER structure which was
1681 not consistent with the structure when d2i_ASN1_INTEGER() was used
1682 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
1683 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
1684 where it did not print out a minus for negative ASN1_INTEGER.
1687 *) Fix 'openssl passwd -1'.
1690 +) Add summary printout to ocsp utility. The various functions which
1691 convert status values to strings have been renamed to:
1692 OCSP_response_status_str(), OCSP_cert_status_str() and
1693 OCSP_crl_reason_str() and are no longer static. New options
1694 to verify nonce values and to disable verification. OCSP response
1695 printout format cleaned up.
1698 +) Add additional OCSP certificate checks. These are those specified
1699 in RFC2560. This consists of two separate checks: the CA of the
1700 certificate being checked must either be the OCSP signer certificate
1701 or the issuer of the OCSP signer certificate. In the latter case the
1702 OCSP signer certificate must contain the OCSP signing extended key
1703 usage. This check is performed by attempting to match the OCSP
1704 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
1705 in the OCSP_CERTID structures of the response.
1708 +) Initial OCSP certificate verification added to OCSP_basic_verify()
1709 and related routines. This uses the standard OpenSSL certificate
1710 verify routines to perform initial checks (just CA validity) and
1711 to obtain the certificate chain. Then additional checks will be
1712 performed on the chain. Currently the root CA is checked to see
1713 if it is explicitly trusted for OCSP signing. This is used to set
1714 a root CA as a global signing root: that is any certificate that
1715 chains to that CA is an acceptable OCSP signing certificate.
1718 +) New '-extfile ...' option to 'openssl ca' for reading X.509v3
1719 extensions from a separate configuration file.
1720 As when reading extensions from the main configuration file,
1721 the '-extensions ...' option may be used for specifying the
1723 [Massimiliano Pala <madwolf@comune.modena.it>]
1725 *) Change PKCS12_key_gen_asc() so it can cope with non null
1726 terminated strings whose length is passed in the passlen
1727 parameter, for example from PEM callbacks. This was done
1728 by adding an extra length parameter to asc2uni().
1729 [Steve Henson, reported by <oddissey@samsung.co.kr>]
1731 +) New OCSP utility. Allows OCSP requests to be generated or
1732 read. The request can be sent to a responder and the output
1733 parsed, outputed or printed in text form. Not complete yet:
1734 still needs to check the OCSP response validity.
1737 +) New subcommands for 'openssl ca':
1738 'openssl ca -status <serial>' prints the status of the cert with
1739 the given serial number (according to the index file).
1740 'openssl ca -updatedb' updates the expiry status of certificates
1742 [Massimiliano Pala <madwolf@comune.modena.it>]
1744 +) New '-newreq-nodes' command option to CA.pl. This is like
1745 '-newreq', but calls 'openssl req' with the '-nodes' option
1746 so that the resulting key is not encrypted.
1747 [Damien Miller <djm@mindrot.org>]
1749 +) New configuration for the GNU Hurd.
1750 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
1752 +) Initial code to implement OCSP basic response verify. This
1753 is currently incomplete. Currently just finds the signer's
1754 certificate and verifies the signature on the response.
1757 +) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
1758 value of OPENSSLDIR. This is available via the new '-d' option
1759 to 'openssl version', and is also included in 'openssl version -a'.
1762 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
1763 call failed, free the DSA structure.
1766 +) Allowing defining memory allocation callbacks that will be given
1767 file name and line number information in additional arguments
1768 (a const char* and an int). The basic functionality remains, as
1769 well as the original possibility to just replace malloc(),
1770 realloc() and free() by functions that do not know about these
1771 additional arguments. To register and find out the current
1772 settings for extended allocation functions, the following
1773 functions are provided:
1775 CRYPTO_set_mem_ex_functions
1776 CRYPTO_set_locked_mem_ex_functions
1777 CRYPTO_get_mem_ex_functions
1778 CRYPTO_get_locked_mem_ex_functions
1780 These work the same way as CRYPTO_set_mem_functions and friends.
1781 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
1782 extended allocation function is enabled.
1783 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
1784 a conventional allocation function is enabled.
1785 [Richard Levitte, Bodo Moeller]
1787 *) Fix to uni2asc() to cope with zero length Unicode strings.
1788 These are present in some PKCS#12 files.
1791 +) Finish off removing the remaining LHASH function pointer casts.
1792 There should no longer be any prototype-casting required when using
1793 the LHASH abstraction, and any casts that remain are "bugs". See
1794 the callback types and macros at the head of lhash.h for details
1795 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
1798 +) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
1799 If /dev/[u]random devices are not available or do not return enough
1800 entropy, EGD style sockets (served by EGD or PRNGD) will automatically
1802 The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
1803 /etc/entropy will be queried once each in this sequence, quering stops
1804 when enough entropy was collected without querying more sockets.
1807 +) Change the Unix RAND_poll() variant to be able to poll several
1808 random devices, as specified by DEVRANDOM, until a sufficient amount
1809 of data has been collected. We spend at most 10 ms on each file
1810 (select timeout) and read in non-blocking mode. DEVRANDOM now
1811 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
1812 (previously it was just the string "/dev/urandom"), so on typical
1813 platforms the 10 ms delay will never occur.
1814 Also separate out the Unix variant to its own file, rand_unix.c.
1815 For VMS, there's a currently-empty rand_vms.c.
1818 +) Move OCSP client related routines to ocsp_cl.c. These
1819 provide utility functions which an application needing
1820 to issue a request to an OCSP responder and analyse the
1821 response will typically need: as opposed to those which an
1822 OCSP responder itself would need which will be added later.
1824 OCSP_request_sign() signs an OCSP request with an API similar
1825 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
1826 response. OCSP_response_get1_basic() extracts basic response
1827 from response. OCSP_resp_find_status(): finds and extracts status
1828 information from an OCSP_CERTID structure (which will be created
1829 when the request structure is built). These are built from lower
1830 level functions which work on OCSP_SINGLERESP structures but
1831 wont normally be used unless the application wishes to examine
1832 extensions in the OCSP response for example.
1834 Replace nonce routines with a pair of functions.
1835 OCSP_request_add1_nonce() adds a nonce value and optionally
1836 generates a random value. OCSP_check_nonce() checks the
1837 validity of the nonce in an OCSP response.
1840 +) Change function OCSP_request_add() to OCSP_request_add0_id().
1841 This doesn't copy the supplied OCSP_CERTID and avoids the
1842 need to free up the newly created id. Change return type
1843 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
1844 This can then be used to add extensions to the request.
1845 Deleted OCSP_request_new(), since most of its functionality
1846 is now in OCSP_REQUEST_new() (and the case insensitive name
1847 clash) apart from the ability to set the request name which
1848 will be added elsewhere.
1851 +) Update OCSP API. Remove obsolete extensions argument from
1852 various functions. Extensions are now handled using the new
1853 OCSP extension code. New simple OCSP HTTP function which
1854 can be used to send requests and parse the response.
1857 +) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
1858 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
1859 uses the special reorder version of SET OF to sort the attributes
1860 and reorder them to match the encoded order. This resolves a long
1861 standing problem: a verify on a PKCS7 structure just after signing
1862 it used to fail because the attribute order did not match the
1863 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
1864 it uses the received order. This is necessary to tolerate some broken
1865 software that does not order SET OF. This is handled by encoding
1866 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
1867 to produce the required SET OF.
1870 +) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
1871 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
1872 files to get correct declarations of the ASN.1 item variables.
1875 +) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
1876 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
1877 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
1878 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
1879 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
1880 ASN1_ITEM and no wrapper functions.
1883 +) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
1884 replace the old function pointer based I/O routines. Change most of
1885 the *_d2i_bio() and *_d2i_fp() functions to use these.
1888 +) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
1889 lines, recognice more "algorithms" that can be deselected, and make
1890 it complain about algorithm deselection that isn't recognised.
1893 +) New ASN1 functions to handle dup, sign, verify, digest, pack and
1894 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
1895 to use new functions. Add NO_ASN1_OLD which can be set to remove
1896 some old style ASN1 functions: this can be used to determine if old
1897 code will still work when these eventually go away.
1900 +) New extension functions for OCSP structures, these follow the
1901 same conventions as certificates and CRLs.
1904 +) New function X509V3_add1_i2d(). This automatically encodes and
1905 adds an extension. Its behaviour can be customised with various
1906 flags to append, replace or delete. Various wrappers added for
1907 certifcates and CRLs.
1910 +) Fix to avoid calling the underlying ASN1 print routine when
1911 an extension cannot be parsed. Correct a typo in the
1912 OCSP_SERVICELOC extension. Tidy up print OCSP format.
1915 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
1916 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
1917 when writing a 32767 byte record.
1918 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
1920 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
1921 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
1923 (RSA objects have a reference count access to which is protected
1924 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
1925 so they are meant to be shared between threads.)
1926 [Bodo Moeller, Geoff Thorpe; original patch submitted by
1927 "Reddie, Steven" <Steven.Reddie@ca.com>]
1929 +) Make mkdef.pl parse some of the ASN1 macros and add apropriate
1930 entries for variables.
1933 *) Fix a deadlock in CRYPTO_mem_leaks().
1936 +) Add functionality to apps/openssl.c for detecting locking
1937 problems: As the program is single-threaded, all we have
1938 to do is register a locking callback using an array for
1939 storing which locks are currently held by the program.
1942 +) Use a lock around the call to CRYPTO_get_ex_new_index() in
1943 SSL_get_ex_data_X509_STORE_idx(), which is used in
1944 ssl_verify_cert_chain() and thus can be called at any time
1945 during TLS/SSL handshakes so that thread-safety is essential.
1946 Unfortunately, the ex_data design is not at all suited
1947 for multi-threaded use, so it probably should be abolished.
1950 +) Added Broadcom "ubsec" ENGINE to OpenSSL.
1951 [Broadcom, tweaked and integrated by Geoff Thorpe]
1953 +) Move common extension printing code to new function
1954 X509V3_print_extensions(). Reorganise OCSP print routines and
1955 implement some needed OCSP ASN1 functions. Add OCSP extensions.
1958 +) New function X509_signature_print() to remove duplication in some
1962 +) Add a special meaning when SET OF and SEQUENCE OF flags are both
1963 set (this was treated exactly the same as SET OF previously). This
1964 is used to reorder the STACK representing the structure to match the
1965 encoding. This will be used to get round a problem where a PKCS7
1966 structure which was signed could not be verified because the STACK
1967 order did not reflect the encoded order.
1970 +) Reimplement the OCSP ASN1 module using the new code.
1973 +) Update the X509V3 code to permit the use of an ASN1_ITEM structure
1974 for its ASN1 operations. The old style function pointers still exist
1975 for now but they will eventually go away.
1978 +) Merge in replacement ASN1 code from the ASN1 branch. This almost
1979 completely replaces the old ASN1 functionality with a table driven
1980 encoder and decoder which interprets an ASN1_ITEM structure describing
1981 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
1982 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
1983 has also been converted to the new form.
1986 +) Change BN_mod_exp_recp so that negative moduli are tolerated
1987 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
1988 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
1989 for negative moduli.
1992 +) Fix BN_uadd and BN_usub: Always return non-negative results instead
1993 of not touching the result's sign bit.
1996 +) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
2000 +) Changed the LHASH code to use prototypes for callbacks, and created
2001 macros to declare and implement thin (optionally static) functions
2002 that provide type-safety and avoid function pointer casting for the
2003 type-specific callbacks.
2006 *) Use better test patterns in bntest.
2009 +) Added Kerberos Cipher Suites to be used with TLS, as written in
2011 [Veers Staats <staatsvr@asc.hpc.mil>,
2012 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
2014 *) rand_win.c fix for Borland C.
2017 *) BN_rshift bugfix for n == 0.
2020 +) Reformat the FAQ so the different questions and answers can be divided
2021 in sections depending on the subject.
2024 +) Have the zlib compression code load ZLIB.DLL dynamically under
2028 +) New function BN_mod_sqrt for computing square roots modulo a prime
2029 (using the probabilistic Tonelli-Shanks algorithm unless
2030 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
2031 be handled deterministically).
2032 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
2034 *) Add a 'bctest' script that checks for some known 'bc' bugs
2035 so that 'make test' does not abort just because 'bc' is broken.
2038 *) Store verify_result within SSL_SESSION also for client side to
2039 avoid potential security hole. (Re-used sessions on the client side
2040 always resulted in verify_result==X509_V_OK, not using the original
2041 result of the server certificate verification.)
2044 +) Make BN_mod_inverse faster by explicitly handling small quotients
2045 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
2046 512 bits], about 30% for larger ones [1024 or 2048 bits].)
2049 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
2050 SSL3_RT_APPLICATION_DATA, return 0.
2051 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
2055 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
2056 releases, have been re-implemented by renaming the previous
2057 implementations of ssl2_read and ssl3_read to ssl2_read_internal
2058 and ssl3_read_internal, respectively, and adding 'peek' parameters
2059 to them. The new ssl[23]_{read,peek} functions are calls to
2060 ssl[23]_read_internal with the 'peek' flag set appropriately.
2061 A 'peek' parameter has also been added to ssl3_read_bytes, which
2062 does the actual work for ssl3_read_internal.
2065 +) New function BN_kronecker.
2068 +) Fix BN_gcd so that it works on negative inputs; the result is
2069 positive unless both parameters are zero.
2070 Previously something reasonably close to an infinite loop was
2071 possible because numbers could be growing instead of shrinking
2072 in the implementation of Euclid's algorithm.
2075 +) Fix BN_is_word() and BN_is_one() macros to take into account the
2076 sign of the number in question.
2078 Fix BN_is_word(a,w) to work correctly for w == 0.
2080 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
2081 because its test if the absolute value of 'a' equals 'w'.
2082 Note that BN_abs_is_word does *not* handle w == 0 reliably;
2083 it exists mostly for use in the implementations of BN_is_zero(),
2084 BN_is_one(), and BN_is_word().
2087 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
2088 the method-specific "init()" handler. Also clean up ex_data after
2089 calling the method-specific "finish()" handler. Previously, this was
2090 happening the other way round.
2093 +) New function BN_swap.
2096 +) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
2097 the exponentiation functions are more likely to produce reasonable
2098 results on negative inputs.
2101 +) Change BN_mod_mul so that the result is always non-negative.
2102 Previously, it could be negative if one of the factors was negative;
2103 I don't think anyone really wanted that behaviour.
2106 +) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
2107 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
2108 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
2109 and add new functions:
2118 BN_mod_lshift1_quick
2122 These functions always generate non-negative results.
2124 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
2125 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
2127 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
2128 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
2129 be reduced modulo m.
2130 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
2132 +) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
2133 was actually never needed) and in BN_mul(). The removal in BN_mul()
2134 required a small change in bn_mul_part_recursive() and the addition
2135 of the functions bn_cmp_part_words(), bn_sub_part_words() and
2136 bn_add_part_words(), which do the same thing as bn_cmp_words(),
2137 bn_sub_words() and bn_add_words() except they take arrays with
2141 +) In 'openssl passwd', verify passwords read from the terminal
2142 unless the '-salt' option is used (which usually means that
2143 verification would just waste user's time since the resulting
2144 hash is going to be compared with some given password hash)
2145 or the new '-noverify' option is used.
2147 This is an incompatible change, but it does not affect
2148 non-interactive use of 'openssl passwd' (passwords on the command
2149 line, '-stdin' option, '-in ...' option) and thus should not
2153 +) Remove all references to RSAref, since there's no more need for it.
2156 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
2157 The previous value, 12, was not always sufficient for BN_mod_exp().
2160 +) Make DSO load along a path given through an environment variable
2161 (SHLIB_PATH) with shl_load().
2164 +) Constify the ENGINE code as a result of BIGNUM constification.
2165 Also constify the RSA code and most things related to it. In a
2166 few places, most notable in the depth of the ASN.1 code, ugly
2167 casts back to non-const were required (to be solved at a later
2171 +) Make it so the openssl application has all engines loaded by default.
2174 +) Constify the BIGNUM routines a little more.
2177 *) Make sure that shared libraries get the internal name engine with
2178 the full version number and not just 0. This should mark the
2179 shared libraries as not backward compatible. Of course, this should
2180 be changed again when we can guarantee backward binary compatibility.
2183 +) Add the following functions:
2185 ENGINE_load_cswift()
2187 ENGINE_load_atalla()
2189 ENGINE_load_builtin_engines()
2191 That way, an application can itself choose if external engines that
2192 are built-in in OpenSSL shall ever be used or not. The benefit is
2193 that applications won't have to be linked with libdl or other dso
2194 libraries unless it's really needed.
2196 Changed 'openssl engine' to load all engines on demand.
2197 Changed the engine header files to avoid the duplication of some
2198 declarations (they differed!).
2201 +) 'openssl engine' can now list capabilities.
2204 +) Better error reporting in 'openssl engine'.
2207 +) Never call load_dh_param(NULL) in s_server.
2210 +) Add engine application. It can currently list engines by name and
2211 identity, and test if they are actually available.
2214 +) Improve RPM specification file by forcing symbolic linking and making
2215 sure the installed documentation is also owned by root.root.
2216 [Damien Miller <djm@mindrot.org>]
2218 +) Give the OpenSSL applications more possibilities to make use of
2219 keys (public as well as private) handled by engines.
2222 +) Add OCSP code that comes from CertCo.
2225 +) Add VMS support for the Rijndael code.
2228 +) Added untested support for Nuron crypto accelerator.
2231 +) Add support for external cryptographic devices. This code was
2232 previously distributed separately as the "engine" branch.
2233 [Geoff Thorpe, Richard Levitte]
2235 +) Rework the filename-translation in the DSO code. It is now possible to
2236 have far greater control over how a "name" is turned into a filename
2237 depending on the operating environment and any oddities about the
2238 different shared library filenames on each system.
2241 +) Support threads on FreeBSD-elf in Configure.
2244 +) Fix for SHA1 assembly problem with MASM: it produces
2245 warnings about corrupt line number information when assembling
2246 with debugging information. This is caused by the overlapping
2248 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
2251 NCONF_get_number() has no error checking at all. As a replacement,
2252 NCONF_get_number_e() is defined (_e for "error checking") and is
2253 promoted strongly. The old NCONF_get_number is kept around for
2254 binary backward compatibility.
2255 Make it possible for methods to load from something other than a BIO,
2256 by providing a function pointer that is given a name instead of a BIO.
2257 For example, this could be used to load configuration data from an
2261 *) Fix typo in get_cert_by_subject() in by_dir.c
2262 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
2264 *) Rework the system to generate shared libraries:
2266 - Make note of the expected extension for the shared libraries and
2267 if there is a need for symbolic links from for example libcrypto.so.0
2268 to libcrypto.so.0.9.7. There is extended info in Configure for
2271 - Make as few rebuilds of the shared libraries as possible.
2273 - Still avoid linking the OpenSSL programs with the shared libraries.
2275 - When installing, install the shared libraries separately from the
2279 +) Fix for non blocking accept BIOs. Added new I/O special reason
2280 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
2281 with non blocking I/O was not possible because no retry code was
2282 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
2286 +) Added the beginnings of Rijndael support.
2289 +) Fix for bug in DirectoryString mask setting. Add support for
2290 X509_NAME_print_ex() in 'req' and X509_print_ex() function
2291 to allow certificate printing to more controllable, additional
2292 'certopt' option to 'x509' to allow new printing options to be
2296 +) Clean old EAY MD5 hack from e_os.h.
2299 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
2301 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
2302 and not in SSL_clear because the latter is also used by the
2303 accept/connect functions; previously, the settings made by
2304 SSL_set_read_ahead would be lost during the handshake.
2305 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
2307 *) Correct util/mkdef.pl to be selective about disabled algorithms.
2308 Previously, it would create entries for disableed algorithms no
2312 *) Added several new manual pages for SSL_* function.
2315 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
2317 *) In ssl23_get_client_hello, generate an error message when faced
2318 with an initial SSL 3.0/TLS record that is too small to contain the
2319 first two bytes of the ClientHello message, i.e. client_version.
2320 (Note that this is a pathologic case that probably has never happened
2321 in real life.) The previous approach was to use the version number
2322 from the record header as a substitute; but our protocol choice
2323 should not depend on that one because it is not authenticated
2324 by the Finished messages.
2327 *) More robust randomness gathering functions for Windows.
2328 [Jeffrey Altman <jaltman@columbia.edu>]
2330 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
2331 not set then we don't setup the error code for issuer check errors
2332 to avoid possibly overwriting other errors which the callback does
2333 handle. If an application does set the flag then we assume it knows
2334 what it is doing and can handle the new informational codes
2338 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
2339 a general "ANY" type, as such it should be able to decode anything
2340 including tagged types. However it didn't check the class so it would
2341 wrongly interpret tagged types in the same way as their universal
2342 counterpart and unknown types were just rejected. Changed so that the
2343 tagged and unknown types are handled in the same way as a SEQUENCE:
2344 that is the encoding is stored intact. There is also a new type
2345 "V_ASN1_OTHER" which is used when the class is not universal, in this
2346 case we have no idea what the actual type is so we just lump them all
2350 *) On VMS, stdout may very well lead to a file that is written to
2351 in a record-oriented fashion. That means that every write() will
2352 write a separate record, which will be read separately by the
2353 programs trying to read from it. This can be very confusing.
2355 The solution is to put a BIO filter in the way that will buffer
2356 text until a linefeed is reached, and then write everything a
2357 line at a time, so every record written will be an actual line,
2358 not chunks of lines and not (usually doesn't happen, but I've
2359 seen it once) several lines in one record. BIO_f_linebuffer() is
2362 Currently, it's a VMS-only method, because that's where it has
2363 been tested well enough.
2366 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
2367 it can return incorrect results.
2368 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
2369 but it was in 0.9.6-beta[12].)
2372 *) Disable the check for content being present when verifying detached
2373 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
2374 include zero length content when signing messages.
2377 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
2378 BIO_ctrl (for BIO pairs).
2381 *) Add DSO method for VMS.
2384 *) Bug fix: Montgomery multiplication could produce results with the
2388 *) Add RPM specification openssl.spec and modify it to build three
2389 packages. The default package contains applications, application
2390 documentation and run-time libraries. The devel package contains
2391 include files, static libraries and function documentation. The
2392 doc package contains the contents of the doc directory. The original
2393 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
2396 *) Add a large number of documentation files for many SSL routines.
2397 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
2399 *) Add a configuration entry for Sony News 4.
2400 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
2402 *) Don't set the two most significant bits to one when generating a
2403 random number < q in the DSA library.
2406 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
2407 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
2408 the underlying transport is blocking) if a handshake took place.
2409 (The default behaviour is needed by applications such as s_client
2410 and s_server that use select() to determine when to use SSL_read;
2411 but for applications that know in advance when to expect data, it
2412 just makes things more complicated.)
2415 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
2419 *) Add a few more EBCDIC conditionals that make `req' and `x509'
2420 work better on such systems.
2421 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2423 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
2424 Update PKCS12_parse() so it copies the friendlyName and the
2425 keyid to the certificates aux info.
2428 *) Fix bug in PKCS7_verify() which caused an infinite loop
2429 if there was more than one signature.
2430 [Sven Uszpelkat <su@celocom.de>]
2432 *) Major change in util/mkdef.pl to include extra information
2433 about each symbol, as well as presentig variables as well
2434 as functions. This change means that there's n more need
2435 to rebuild the .num files when some algorithms are excluded.
2438 *) Allow the verify time to be set by an application,
2439 rather than always using the current time.
2442 *) Phase 2 verify code reorganisation. The certificate
2443 verify code now looks up an issuer certificate by a
2444 number of criteria: subject name, authority key id
2445 and key usage. It also verifies self signed certificates
2446 by the same criteria. The main comparison function is
2447 X509_check_issued() which performs these checks.
2449 Lot of changes were necessary in order to support this
2450 without completely rewriting the lookup code.
2452 Authority and subject key identifier are now cached.
2454 The LHASH 'certs' is X509_STORE has now been replaced
2455 by a STACK_OF(X509_OBJECT). This is mainly because an
2456 LHASH can't store or retrieve multiple objects with
2457 the same hash value.
2459 As a result various functions (which were all internal
2460 use only) have changed to handle the new X509_STORE
2461 structure. This will break anything that messed round
2462 with X509_STORE internally.
2464 The functions X509_STORE_add_cert() now checks for an
2465 exact match, rather than just subject name.
2467 The X509_STORE API doesn't directly support the retrieval
2468 of multiple certificates matching a given criteria, however
2469 this can be worked round by performing a lookup first
2470 (which will fill the cache with candidate certificates)
2471 and then examining the cache for matches. This is probably
2472 the best we can do without throwing out X509_LOOKUP
2473 entirely (maybe later...).
2475 The X509_VERIFY_CTX structure has been enhanced considerably.
2477 All certificate lookup operations now go via a get_issuer()
2478 callback. Although this currently uses an X509_STORE it
2479 can be replaced by custom lookups. This is a simple way
2480 to bypass the X509_STORE hackery necessary to make this
2481 work and makes it possible to use more efficient techniques
2482 in future. A very simple version which uses a simple
2483 STACK for its trusted certificate store is also provided
2484 using X509_STORE_CTX_trusted_stack().
2486 The verify_cb() and verify() callbacks now have equivalents
2487 in the X509_STORE_CTX structure.
2489 X509_STORE_CTX also has a 'flags' field which can be used
2490 to customise the verify behaviour.
2493 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
2494 excludes S/MIME capabilities.
2497 *) When a certificate request is read in keep a copy of the
2498 original encoding of the signed data and use it when outputing
2499 again. Signatures then use the original encoding rather than
2500 a decoded, encoded version which may cause problems if the
2501 request is improperly encoded.
2504 *) For consistency with other BIO_puts implementations, call
2505 buffer_write(b, ...) directly in buffer_puts instead of calling
2508 In BIO_puts, increment b->num_write as in BIO_write.
2509 [Peter.Sylvester@EdelWeb.fr]
2511 *) Fix BN_mul_word for the case where the word is 0. (We have to use
2512 BN_zero, we may not return a BIGNUM with an array consisting of
2516 *) Avoid calling abort() from within the library when problems are
2517 detected, except if preprocessor symbols have been defined
2518 (such as REF_CHECK, BN_DEBUG etc.).
2521 *) New openssl application 'rsautl'. This utility can be
2522 used for low level RSA operations. DER public key
2523 BIO/fp routines also added.
2526 *) New Configure entry and patches for compiling on QNX 4.
2527 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
2529 *) A demo state-machine implementation was sponsored by
2530 Nuron (http://www.nuron.com/) and is now available in
2531 demos/state_machine.
2534 *) New options added to the 'dgst' utility for signature
2535 generation and verification.
2538 *) Unrecognized PKCS#7 content types are now handled via a
2539 catch all ASN1_TYPE structure. This allows unsupported
2540 types to be stored as a "blob" and an application can
2541 encode and decode it manually.
2544 *) Fix various signed/unsigned issues to make a_strex.c
2546 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
2548 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
2549 length if passed a buffer. ASN1_INTEGER_to_BN failed
2550 if passed a NULL BN and its argument was negative.
2551 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
2553 *) Modification to PKCS#7 encoding routines to output definite
2554 length encoding. Since currently the whole structures are in
2555 memory there's not real point in using indefinite length
2556 constructed encoding. However if OpenSSL is compiled with
2557 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
2560 *) Added BIO_vprintf() and BIO_vsnprintf().
2563 *) Added more prefixes to parse for in the the strings written
2564 through a logging bio, to cover all the levels that are available
2565 through syslog. The prefixes are now:
2567 PANIC, EMERG, EMR => LOG_EMERG
2568 ALERT, ALR => LOG_ALERT
2569 CRIT, CRI => LOG_CRIT
2570 ERROR, ERR => LOG_ERR
2571 WARNING, WARN, WAR => LOG_WARNING
2572 NOTICE, NOTE, NOT => LOG_NOTICE
2573 INFO, INF => LOG_INFO
2574 DEBUG, DBG => LOG_DEBUG
2576 and as before, if none of those prefixes are present at the
2577 beginning of the string, LOG_ERR is chosen.
2579 On Win32, the LOG_* levels are mapped according to this:
2581 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
2582 LOG_WARNING => EVENTLOG_WARNING_TYPE
2583 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
2587 *) Made it possible to reconfigure with just the configuration
2588 argument "reconf" or "reconfigure". The command line arguments
2589 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
2590 and are retrieved from there when reconfiguring.
2594 [Assar Westerlund <assar@sics.se>, Richard Levitte]
2596 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
2599 *) The obj_dat.pl script was messing up the sorting of object
2600 names. The reason was that it compared the quoted version
2601 of strings as a result "OCSP" > "OCSP Signing" because
2602 " > SPACE. Changed script to store unquoted versions of
2603 names and add quotes on output. It was also omitting some
2604 names from the lookup table if they were given a default
2605 value (that is if SN is missing it is given the same
2606 value as LN and vice versa), these are now added on the
2607 grounds that if an object has a name we should be able to
2608 look it up. Finally added warning output when duplicate
2609 short or long names are found.
2612 *) Changes needed for Tandem NSK.
2613 [Scott Uroff <scott@xypro.com>]
2615 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
2616 RSA_padding_check_SSLv23(), special padding was never detected
2617 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
2618 version rollback attacks was not effective.
2620 In s23_clnt.c, don't use special rollback-attack detection padding
2621 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
2622 client; similarly, in s23_srvr.c, don't do the rollback check if
2623 SSL 2.0 is the only protocol enabled in the server.
2626 *) Make it possible to get hexdumps of unprintable data with 'openssl
2627 asn1parse'. By implication, the functions ASN1_parse_dump() and
2628 BIO_dump_indent() are added.
2631 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
2632 these print out strings and name structures based on various
2633 flags including RFC2253 support and proper handling of
2634 multibyte characters. Added options to the 'x509' utility
2635 to allow the various flags to be set.
2638 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
2639 Also change the functions X509_cmp_current_time() and
2640 X509_gmtime_adj() work with an ASN1_TIME structure,
2641 this will enable certificates using GeneralizedTime in validity
2642 dates to be checked.
2645 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
2646 negative public key encodings) on by default,
2647 NO_NEG_PUBKEY_BUG can be set to disable it.
2650 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
2651 content octets. An i2c_ASN1_OBJECT is unnecessary because
2652 the encoding can be trivially obtained from the structure.
2655 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
2656 not read locks (CRYPTO_r_[un]lock).
2659 *) A first attempt at creating official support for shared
2660 libraries through configuration. I've kept it so the
2661 default is static libraries only, and the OpenSSL programs
2662 are always statically linked for now, but there are
2663 preparations for dynamic linking in place.
2664 This has been tested on Linux and Tru64.
2667 *) Randomness polling function for Win9x, as described in:
2668 Peter Gutmann, Software Generation of Practically Strong
2672 *) Fix so PRNG is seeded in req if using an already existing
2676 *) New options to smime application. -inform and -outform
2677 allow alternative formats for the S/MIME message including
2678 PEM and DER. The -content option allows the content to be
2679 specified separately. This should allow things like Netscape
2680 form signing output easier to verify.
2683 *) Fix the ASN1 encoding of tags using the 'long form'.
2686 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
2687 STRING types. These convert content octets to and from the
2688 underlying type. The actual tag and length octets are
2689 already assumed to have been read in and checked. These
2690 are needed because all other string types have virtually
2691 identical handling apart from the tag. By having versions
2692 of the ASN1 functions that just operate on content octets
2693 IMPLICIT tagging can be handled properly. It also allows
2694 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
2695 and ASN1_INTEGER are identical apart from the tag.
2698 *) Change the handling of OID objects as follows:
2700 - New object identifiers are inserted in objects.txt, following
2701 the syntax given in objects.README.
2702 - objects.pl is used to process obj_mac.num and create a new
2704 - obj_dat.pl is used to create a new obj_dat.h, using the data in
2707 This is currently kind of a hack, and the perl code in objects.pl
2708 isn't very elegant, but it works as I intended. The simplest way
2709 to check that it worked correctly is to look in obj_dat.h and
2710 check the array nid_objs and make sure the objects haven't moved
2711 around (this is important!). Additions are OK, as well as
2712 consistent name changes.
2715 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
2718 *) Addition of the command line parameter '-rand file' to 'openssl req'.
2719 The given file adds to whatever has already been seeded into the
2720 random pool through the RANDFILE configuration file option or
2721 environment variable, or the default random state file.
2724 *) mkstack.pl now sorts each macro group into lexical order.
2725 Previously the output order depended on the order the files
2726 appeared in the directory, resulting in needless rewriting
2730 *) Patches to make OpenSSL compile under Win32 again. Mostly
2731 work arounds for the VC++ problem that it treats func() as
2732 func(void). Also stripped out the parts of mkdef.pl that
2733 added extra typesafe functions: these no longer exist.
2736 *) Reorganisation of the stack code. The macros are now all
2737 collected in safestack.h . Each macro is defined in terms of
2738 a "stack macro" of the form SKM_<name>(type, a, b). The
2739 DEBUG_SAFESTACK is now handled in terms of function casts,
2740 this has the advantage of retaining type safety without the
2741 use of additional functions. If DEBUG_SAFESTACK is not defined
2742 then the non typesafe macros are used instead. Also modified the
2743 mkstack.pl script to handle the new form. Needs testing to see
2744 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
2745 the default if no major problems. Similar behaviour for ASN1_SET_OF
2746 and PKCS12_STACK_OF.
2749 *) When some versions of IIS use the 'NET' form of private key the
2750 key derivation algorithm is different. Normally MD5(password) is
2751 used as a 128 bit RC4 key. In the modified case
2752 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
2753 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
2754 as the old Netscape_RSA functions except they have an additional
2755 'sgckey' parameter which uses the modified algorithm. Also added
2756 an -sgckey command line option to the rsa utility. Thanks to
2757 Adrian Peck <bertie@ncipher.com> for posting details of the modified
2758 algorithm to openssl-dev.
2761 *) The evp_local.h macros were using 'c.##kname' which resulted in
2762 invalid expansion on some systems (SCO 5.0.5 for example).
2763 Corrected to 'c.kname'.
2764 [Phillip Porch <root@theporch.com>]
2766 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
2767 a STACK of email addresses from a certificate or request, these look
2768 in the subject name and the subject alternative name extensions and
2769 omit any duplicate addresses.
2772 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
2773 This makes DSA verification about 2 % faster.
2776 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
2777 (meaning that now 2^5 values will be precomputed, which is only 4 KB
2778 plus overhead for 1024 bit moduli).
2779 This makes exponentiations about 0.5 % faster for 1024 bit
2780 exponents (as measured by "openssl speed rsa2048").
2783 *) Rename memory handling macros to avoid conflicts with other
2785 Malloc => OPENSSL_malloc
2786 Malloc_locked => OPENSSL_malloc_locked
2787 Realloc => OPENSSL_realloc
2788 Free => OPENSSL_free
2791 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
2792 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
2795 *) CygWin32 support.
2796 [John Jarvie <jjarvie@newsguy.com>]
2798 *) The type-safe stack code has been rejigged. It is now only compiled
2799 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
2800 by default all type-specific stack functions are "#define"d back to
2801 standard stack functions. This results in more streamlined output
2802 but retains the type-safety checking possibilities of the original
2806 *) The STACK code has been cleaned up, and certain type declarations
2807 that didn't make a lot of sense have been brought in line. This has
2808 also involved a cleanup of sorts in safestack.h to more correctly
2809 map type-safe stack functions onto their plain stack counterparts.
2810 This work has also resulted in a variety of "const"ifications of
2811 lots of the code, especially "_cmp" operations which should normally
2812 be prototyped with "const" parameters anyway.
2815 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
2816 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
2817 (The PRNG state consists of two parts, the large pool 'state' and 'md',
2818 where all of 'md' is used each time the PRNG is used, but 'state'
2819 is used only indexed by a cyclic counter. As entropy may not be
2820 well distributed from the beginning, 'md' is important as a
2821 chaining variable. However, the output function chains only half
2822 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
2823 all of 'md', and seeding with STATE_SIZE dummy bytes will result
2824 in all of 'state' being rewritten, with the new values depending
2825 on virtually all of 'md'. This overcomes the 80 bit limitation.)
2828 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
2829 the handshake is continued after ssl_verify_cert_chain();
2830 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
2831 can lead to 'unexplainable' connection aborts later.
2832 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
2834 *) Major EVP API cipher revision.
2835 Add hooks for extra EVP features. This allows various cipher
2836 parameters to be set in the EVP interface. Support added for variable
2837 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
2838 setting of RC2 and RC5 parameters.
2840 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
2843 Remove lots of duplicated code from the EVP library. For example *every*
2844 cipher init() function handles the 'iv' in the same way according to the
2845 cipher mode. They also all do nothing if the 'key' parameter is NULL and
2846 for CFB and OFB modes they zero ctx->num.
2848 New functionality allows removal of S/MIME code RC2 hack.
2850 Most of the routines have the same form and so can be declared in terms
2853 By shifting this to the top level EVP_CipherInit() it can be removed from
2854 all individual ciphers. If the cipher wants to handle IVs or keys
2855 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
2858 Change lots of functions like EVP_EncryptUpdate() to now return a
2859 value: although software versions of the algorithms cannot fail
2860 any installed hardware versions can.
2863 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
2864 this option is set, tolerate broken clients that send the negotiated
2865 protocol version number instead of the requested protocol version
2869 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
2870 i.e. non-zero for export ciphersuites, zero otherwise.
2871 Previous versions had this flag inverted, inconsistent with
2872 rsa_tmp_cb (..._TMP_RSA_CB).
2873 [Bodo Moeller; problem reported by Amit Chopra]
2875 *) Add missing DSA library text string. Work around for some IIS
2876 key files with invalid SEQUENCE encoding.
2879 *) Add a document (doc/standards.txt) that list all kinds of standards
2880 and so on that are implemented in OpenSSL.
2883 *) Enhance c_rehash script. Old version would mishandle certificates
2884 with the same subject name hash and wouldn't handle CRLs at all.
2885 Added -fingerprint option to crl utility, to support new c_rehash
2889 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
2892 *) Fix for SSL server purpose checking. Server checking was
2893 rejecting certificates which had extended key usage present
2894 but no ssl client purpose.
2895 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
2897 *) Make PKCS#12 code work with no password. The PKCS#12 spec
2898 is a little unclear about how a blank password is handled.
2899 Since the password in encoded as a BMPString with terminating
2900 double NULL a zero length password would end up as just the
2901 double NULL. However no password at all is different and is
2902 handled differently in the PKCS#12 key generation code. NS
2903 treats a blank password as zero length. MSIE treats it as no
2904 password on export: but it will try both on import. We now do
2905 the same: PKCS12_parse() tries zero length and no password if
2906 the password is set to "" or NULL (NULL is now a valid password:
2907 it wasn't before) as does the pkcs12 application.
2910 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
2911 perror when PEM_read_bio_X509_REQ fails, the error message must
2912 be obtained from the error queue.
2915 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
2916 it in ERR_remove_state if appropriate, and change ERR_get_state
2917 accordingly to avoid race conditions (this is necessary because
2918 thread_hash is no longer constant once set).
2921 *) Bugfix for linux-elf makefile.one.
2924 *) RSA_get_default_method() will now cause a default
2925 RSA_METHOD to be chosen if one doesn't exist already.
2926 Previously this was only set during a call to RSA_new()
2927 or RSA_new_method(NULL) meaning it was possible for
2928 RSA_get_default_method() to return NULL.
2931 *) Added native name translation to the existing DSO code
2932 that will convert (if the flag to do so is set) filenames
2933 that are sufficiently small and have no path information
2934 into a canonical native form. Eg. "blah" converted to
2935 "libblah.so" or "blah.dll" etc.
2938 *) New function ERR_error_string_n(e, buf, len) which is like
2939 ERR_error_string(e, buf), but writes at most 'len' bytes
2940 including the 0 terminator. For ERR_error_string_n, 'buf'
2942 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
2944 *) CONF library reworked to become more general. A new CONF
2945 configuration file reader "class" is implemented as well as a
2946 new functions (NCONF_*, for "New CONF") to handle it. The now
2947 old CONF_* functions are still there, but are reimplemented to
2948 work in terms of the new functions. Also, a set of functions
2949 to handle the internal storage of the configuration data is
2950 provided to make it easier to write new configuration file
2951 reader "classes" (I can definitely see something reading a
2952 configuration file in XML format, for example), called _CONF_*,
2953 or "the configuration storage API"...
2955 The new configuration file reading functions are:
2957 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
2958 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
2960 NCONF_default, NCONF_WIN32
2962 NCONF_dump_fp, NCONF_dump_bio
2964 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
2965 NCONF_new creates a new CONF object. This works in the same way
2966 as other interfaces in OpenSSL, like the BIO interface.
2967 NCONF_dump_* dump the internal storage of the configuration file,
2968 which is useful for debugging. All other functions take the same
2969 arguments as the old CONF_* functions wth the exception of the
2970 first that must be a `CONF *' instead of a `LHASH *'.
2972 To make it easer to use the new classes with the old CONF_* functions,
2973 the function CONF_set_default_method is provided.
2976 *) Add '-tls1' option to 'openssl ciphers', which was already
2977 mentioned in the documentation but had not been implemented.
2978 (This option is not yet really useful because even the additional
2979 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
2982 *) Initial DSO code added into libcrypto for letting OpenSSL (and
2983 OpenSSL-based applications) load shared libraries and bind to
2984 them in a portable way.
2985 [Geoff Thorpe, with contributions from Richard Levitte]
2987 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
2989 *) Make sure _lrotl and _lrotr are only used with MSVC.
2991 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
2992 (the default implementation of RAND_status).
2994 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
2995 to '-clrext' (= clear extensions), as intended and documented.
2996 [Bodo Moeller; inconsistency pointed out by Michael Attili
2999 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
3000 was larger than the MD block size.
3001 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
3003 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
3004 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
3005 using the passed key: if the passed key was a private key the result
3006 of X509_print(), for example, would be to print out all the private key
3010 *) des_quad_cksum() byte order bug fix.
3011 [Ulf Möller, using the problem description in krb4-0.9.7, where
3012 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
3014 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
3016 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
3018 *) For easily testing in shell scripts whether some command
3019 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
3020 returns with exit code 0 iff no command of the given name is available.
3021 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
3022 the output goes to stdout and nothing is printed to stderr.
3023 Additional arguments are always ignored.
3025 Since for each cipher there is a command of the same name,
3026 the 'no-cipher' compilation switches can be tested this way.
3028 ('openssl no-XXX' is not able to detect pseudo-commands such
3029 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
3032 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
3035 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
3036 is set; it will be thrown away anyway because each handshake creates
3038 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
3039 to parameters -- in previous versions (since OpenSSL 0.9.3) the
3040 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
3041 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
3044 *) New s_client option -ign_eof: EOF at stdin is ignored, and
3045 'Q' and 'R' lose their special meanings (quit/renegotiate).
3046 This is part of what -quiet does; unlike -quiet, -ign_eof
3047 does not suppress any output.
3050 *) Add compatibility options to the purpose and trust code. The
3051 purpose X509_PURPOSE_ANY is "any purpose" which automatically
3052 accepts a certificate or CA, this was the previous behaviour,
3053 with all the associated security issues.
3055 X509_TRUST_COMPAT is the old trust behaviour: only and
3056 automatically trust self signed roots in certificate store. A
3057 new trust setting X509_TRUST_DEFAULT is used to specify that
3058 a purpose has no associated trust setting and it should instead
3059 use the value in the default purpose.
3062 *) Fix the PKCS#8 DSA private key code so it decodes keys again
3063 and fix a memory leak.
3066 *) In util/mkerr.pl (which implements 'make errors'), preserve
3067 reason strings from the previous version of the .c file, as
3068 the default to have only downcase letters (and digits) in
3069 automatically generated reasons codes is not always appropriate.
3072 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
3073 using strerror. Previously, ERR_reason_error_string() returned
3074 library names as reason strings for SYSerr; but SYSerr is a special
3075 case where small numbers are errno values, not library numbers.
3078 *) Add '-dsaparam' option to 'openssl dhparam' application. This
3079 converts DSA parameters into DH parameters. (When creating parameters,
3080 DSA_generate_parameters is used.)
3083 *) Include 'length' (recommended exponent length) in C code generated
3084 by 'openssl dhparam -C'.
3087 *) The second argument to set_label in perlasm was already being used
3088 so couldn't be used as a "file scope" flag. Moved to third argument
3092 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
3093 instead of RAND_bytes for encryption IVs and salts.
3096 *) Include RAND_status() into RAND_METHOD instead of implementing
3097 it only for md_rand.c Otherwise replacing the PRNG by calling
3098 RAND_set_rand_method would be impossible.
3101 *) Don't let DSA_generate_key() enter an infinite loop if the random
3102 number generation fails.
3105 *) New 'rand' application for creating pseudo-random output.
3108 *) Added configuration support for Linux/IA64
3109 [Rolf Haberrecker <rolf@suse.de>]
3111 *) Assembler module support for Mingw32.
3114 *) Shared library support for HPUX (in shlib/).
3115 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
3117 *) Shared library support for Solaris gcc.
3118 [Lutz Behnke <behnke@trustcenter.de>]
3120 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
3122 *) PKCS7_encrypt() was adding text MIME headers twice because they
3123 were added manually and by SMIME_crlf_copy().
3126 *) In bntest.c don't call BN_rand with zero bits argument.
3127 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
3129 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
3130 case was implemented. This caused BN_div_recp() to fail occasionally.
3133 *) Add an optional second argument to the set_label() in the perl
3134 assembly language builder. If this argument exists and is set
3135 to 1 it signals that the assembler should use a symbol whose
3136 scope is the entire file, not just the current function. This
3137 is needed with MASM which uses the format label:: for this scope.
3138 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
3140 *) Change the ASN1 types so they are typedefs by default. Before
3141 almost all types were #define'd to ASN1_STRING which was causing
3142 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
3146 *) Change names of new functions to the new get1/get0 naming
3147 convention: After 'get1', the caller owns a reference count
3148 and has to call ..._free; 'get0' returns a pointer to some
3149 data structure without incrementing reference counters.
3150 (Some of the existing 'get' functions increment a reference
3151 counter, some don't.)
3152 Similarly, 'set1' and 'add1' functions increase reference
3153 counters or duplicate objects.
3156 *) Allow for the possibility of temp RSA key generation failure:
3157 the code used to assume it always worked and crashed on failure.
3160 *) Fix potential buffer overrun problem in BIO_printf().
3161 [Ulf Möller, using public domain code by Patrick Powell; problem
3162 pointed out by David Sacerdote <das33@cornell.edu>]
3164 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
3165 RAND_egd() and RAND_status(). In the command line application,
3166 the EGD socket can be specified like a seed file using RANDFILE
3170 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
3171 Some CAs (e.g. Verisign) distribute certificates in this form.
3174 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
3175 list to exclude them. This means that no special compilation option
3176 is needed to use anonymous DH: it just needs to be included in the
3180 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
3181 EVP_MD_type. The old functionality is available in a new macro called
3182 EVP_MD_md(). Change code that uses it and update docs.
3185 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
3186 where the 'void *' argument is replaced by a function pointer argument.
3187 Previously 'void *' was abused to point to functions, which works on
3188 many platforms, but is not correct. As these functions are usually
3189 called by macros defined in OpenSSL header files, most source code
3190 should work without changes.
3193 *) <openssl/opensslconf.h> (which is created by Configure) now contains
3194 sections with information on -D... compiler switches used for
3195 compiling the library so that applications can see them. To enable
3196 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
3197 must be defined. E.g.,
3198 #define OPENSSL_ALGORITHM_DEFINES
3199 #include <openssl/opensslconf.h>
3200 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
3201 [Richard Levitte, Ulf and Bodo Möller]
3203 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
3207 *) Change the 'other' type in certificate aux info to a STACK_OF
3208 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
3209 the required ASN1 format: arbitrary types determined by an OID.
3212 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
3213 argument to 'req'. This is not because the function is newer or
3214 better than others it just uses the work 'NEW' in the certificate
3215 request header lines. Some software needs this.
3218 *) Reorganise password command line arguments: now passwords can be
3219 obtained from various sources. Delete the PEM_cb function and make
3220 it the default behaviour: i.e. if the callback is NULL and the
3221 usrdata argument is not NULL interpret it as a null terminated pass
3222 phrase. If usrdata and the callback are NULL then the pass phrase
3223 is prompted for as usual.
3226 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
3227 the support is automatically enabled. The resulting binaries will
3228 autodetect the card and use it if present.
3229 [Ben Laurie and Compaq Inc.]
3231 *) Work around for Netscape hang bug. This sends certificate request
3232 and server done in one record. Since this is perfectly legal in the
3233 SSL/TLS protocol it isn't a "bug" option and is on by default. See
3234 the bugs/SSLv3 entry for more info.
3237 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
3240 *) Add -rand argument to smime and pkcs12 applications and read/write
3244 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
3247 *) Add command line password options to the remaining applications.
3250 *) Bug fix for BN_div_recp() for numerators with an even number of
3254 *) More tests in bntest.c, and changed test_bn output.
3257 *) ./config recognizes MacOS X now.
3260 *) Bug fix for BN_div() when the first words of num and divsor are
3261 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
3264 *) Add support for various broken PKCS#8 formats, and command line
3265 options to produce them.
3268 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
3269 get temporary BIGNUMs from a BN_CTX.
3272 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
3276 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
3277 include a #define from the old name to the new. The original intent
3278 was that statically linked binaries could for example just call
3279 SSLeay_add_all_ciphers() to just add ciphers to the table and not
3280 link with digests. This never worked becayse SSLeay_add_all_digests()
3281 and SSLeay_add_all_ciphers() were in the same source file so calling
3282 one would link with the other. They are now in separate source files.
3285 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
3288 *) Use a less unusual form of the Miller-Rabin primality test (it used
3289 a binary algorithm for exponentiation integrated into the Miller-Rabin
3290 loop, our standard modexp algorithms are faster).
3293 *) Support for the EBCDIC character set completed.
3294 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
3296 *) Source code cleanups: use const where appropriate, eliminate casts,
3297 use void * instead of char * in lhash.
3300 *) Bugfix: ssl3_send_server_key_exchange was not restartable
3301 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
3302 this the server could overwrite ephemeral keys that the client
3306 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
3307 using 50 iterations of the Rabin-Miller test.
3309 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
3310 iterations of the Rabin-Miller test as required by the appendix
3311 to FIPS PUB 186[-1]) instead of DSA_is_prime.
3312 As BN_is_prime_fasttest includes trial division, DSA parameter
3313 generation becomes much faster.
3315 This implies a change for the callback functions in DSA_is_prime
3316 and DSA_generate_parameters: The callback function is called once
3317 for each positive witness in the Rabin-Miller test, not just
3318 occasionally in the inner loop; and the parameters to the
3319 callback function now provide an iteration count for the outer
3320 loop rather than for the current invocation of the inner loop.
3321 DSA_generate_parameters additionally can call the callback
3322 function with an 'iteration count' of -1, meaning that a
3323 candidate has passed the trial division test (when q is generated
3324 from an application-provided seed, trial division is skipped).
3327 *) New function BN_is_prime_fasttest that optionally does trial
3328 division before starting the Rabin-Miller test and has
3329 an additional BN_CTX * argument (whereas BN_is_prime always
3330 has to allocate at least one BN_CTX).
3331 'callback(1, -1, cb_arg)' is called when a number has passed the
3332 trial division stage.
3335 *) Fix for bug in CRL encoding. The validity dates weren't being handled
3339 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
3342 *) New function BN_pseudo_rand().
3345 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
3346 bignum version of BN_from_montgomery() with the working code from
3347 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
3351 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
3352 made it impossible to use the same SSL_SESSION data structure in
3353 SSL2 clients in multiple threads.
3356 *) The return value of RAND_load_file() no longer counts bytes obtained
3357 by stat(). RAND_load_file(..., -1) is new and uses the complete file
3358 to seed the PRNG (previously an explicit byte count was required).
3359 [Ulf Möller, Bodo Möller]
3361 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
3362 used (char *) instead of (void *) and had casts all over the place.
3365 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
3368 *) Retain source code compatibility for BN_prime_checks macro:
3369 BN_is_prime(..., BN_prime_checks, ...) now uses
3370 BN_prime_checks_for_size to determine the appropriate number of
3371 Rabin-Miller iterations.
3374 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
3375 DH_CHECK_P_NOT_SAFE_PRIME.
3376 (Check if this is true? OpenPGP calls them "strong".)
3379 *) Merge the functionality of "dh" and "gendh" programs into a new program
3380 "dhparam". The old programs are retained for now but will handle DH keys
3381 (instead of parameters) in future.
3384 *) Make the ciphers, s_server and s_client programs check the return values
3385 when a new cipher list is set.
3388 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
3389 ciphers. Before when the 56bit ciphers were enabled the sorting was
3392 The syntax for the cipher sorting has been extended to support sorting by
3393 cipher-strength (using the strength_bits hard coded in the tables).
3394 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
3396 Fix a bug in the cipher-command parser: when supplying a cipher command
3397 string with an "undefined" symbol (neither command nor alphanumeric
3398 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
3399 an error is flagged.
3401 Due to the strength-sorting extension, the code of the
3402 ssl_create_cipher_list() function was completely rearranged. I hope that
3403 the readability was also increased :-)
3404 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
3406 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
3407 for the first serial number and places 2 in the serial number file. This
3408 avoids problems when the root CA is created with serial number zero and
3409 the first user certificate has the same issuer name and serial number
3413 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
3414 the new code. Add documentation for this stuff.
3417 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
3418 X509_*() to X509at_*() on the grounds that they don't handle X509
3419 structures and behave in an analagous way to the X509v3 functions:
3420 they shouldn't be called directly but wrapper functions should be used
3423 So we also now have some wrapper functions that call the X509at functions
3424 when passed certificate requests. (TO DO: similar things can be done with
3425 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
3426 things. Some of these need some d2i or i2d and print functionality
3427 because they handle more complex structures.)
3430 *) Add missing #ifndefs that caused missing symbols when building libssl
3431 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
3432 NO_RSA in ssl/s2*.c.
3433 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
3435 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
3436 has a return value which indicates the quality of the random data
3437 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
3438 error queue. New function RAND_pseudo_bytes() generates output that is
3439 guaranteed to be unique but not unpredictable. RAND_add is like
3440 RAND_seed, but takes an extra argument for an entropy estimate
3441 (RAND_seed always assumes full entropy).
3444 *) Do more iterations of Rabin-Miller probable prime test (specifically,
3445 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
3446 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
3447 in crypto/bn/bn_prime.c for the complete table). This guarantees a
3448 false-positive rate of at most 2^-80 for random input.
3451 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
3454 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
3455 in the 0.9.5 release), this returns the chain
3456 from an X509_CTX structure with a dup of the stack and all
3457 the X509 reference counts upped: so the stack will exist
3458 after X509_CTX_cleanup() has been called. Modify pkcs12.c
3461 Also make SSL_SESSION_print() print out the verify return
3465 *) Add manpage for the pkcs12 command. Also change the default
3466 behaviour so MAC iteration counts are used unless the new
3467 -nomaciter option is used. This improves file security and
3468 only older versions of MSIE (4.0 for example) need it.
3471 *) Honor the no-xxx Configure options when creating .DEF files.
3474 *) Add PKCS#10 attributes to field table: challengePassword,
3475 unstructuredName and unstructuredAddress. These are taken from
3476 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
3477 international characters are used.
3479 More changes to X509_ATTRIBUTE code: allow the setting of types
3480 based on strings. Remove the 'loc' parameter when adding
3481 attributes because these will be a SET OF encoding which is sorted
3485 *) Initial changes to the 'req' utility to allow request generation
3486 automation. This will allow an application to just generate a template
3487 file containing all the field values and have req construct the
3490 Initial support for X509_ATTRIBUTE handling. Stacks of these are
3491 used all over the place including certificate requests and PKCS#7
3492 structures. They are currently handled manually where necessary with
3493 some primitive wrappers for PKCS#7. The new functions behave in a
3494 manner analogous to the X509 extension functions: they allow
3495 attributes to be looked up by NID and added.
3497 Later something similar to the X509V3 code would be desirable to
3498 automatically handle the encoding, decoding and printing of the
3499 more complex types. The string types like challengePassword can
3500 be handled by the string table functions.
3502 Also modified the multi byte string table handling. Now there is
3503 a 'global mask' which masks out certain types. The table itself
3504 can use the flag STABLE_NO_MASK to ignore the mask setting: this
3505 is useful when for example there is only one permissible type
3506 (as in countryName) and using the mask might result in no valid
3510 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
3511 SSL_get_peer_finished to allow applications to obtain the latest
3512 Finished messages sent to the peer or expected from the peer,
3513 respectively. (SSL_get_peer_finished is usually the Finished message
3514 actually received from the peer, otherwise the protocol will be aborted.)
3516 As the Finished message are message digests of the complete handshake
3517 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
3518 be used for external authentication procedures when the authentication
3519 provided by SSL/TLS is not desired or is not enough.
3522 *) Enhanced support for Alpha Linux is added. Now ./config checks if
3523 the host supports BWX extension and if Compaq C is present on the
3524 $PATH. Just exploiting of the BWX extension results in 20-30%
3525 performance kick for some algorithms, e.g. DES and RC4 to mention
3526 a couple. Compaq C in turn generates ~20% faster code for MD5 and
3530 *) Add support for MS "fast SGC". This is arguably a violation of the
3531 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
3532 weak crypto and after checking the certificate is SGC a second one
3533 with strong crypto. MS SGC stops the first handshake after receiving
3534 the server certificate message and sends a second client hello. Since
3535 a server will typically do all the time consuming operations before
3536 expecting any further messages from the client (server key exchange
3537 is the most expensive) there is little difference between the two.
3539 To get OpenSSL to support MS SGC we have to permit a second client
3540 hello message after we have sent server done. In addition we have to
3541 reset the MAC if we do get this second client hello.
3544 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
3545 if a DER encoded private key is RSA or DSA traditional format. Changed
3546 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
3547 format DER encoded private key. Newer code should use PKCS#8 format which
3548 has the key type encoded in the ASN1 structure. Added DER private key
3549 support to pkcs8 application.
3552 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
3553 ciphersuites has been selected (as required by the SSL 3/TLS 1
3554 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
3555 is set, we interpret this as a request to violate the specification
3556 (the worst that can happen is a handshake failure, and 'correct'
3557 behaviour would result in a handshake failure anyway).
3560 *) In SSL_CTX_add_session, take into account that there might be multiple
3561 SSL_SESSION structures with the same session ID (e.g. when two threads
3562 concurrently obtain them from an external cache).
3563 The internal cache can handle only one SSL_SESSION with a given ID,
3564 so if there's a conflict, we now throw out the old one to achieve
3568 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
3569 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
3570 some routines that use cipher OIDs: some ciphers do not have OIDs
3571 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
3575 *) Simplify the trust setting structure and code. Now we just have
3576 two sequences of OIDs for trusted and rejected settings. These will
3577 typically have values the same as the extended key usage extension
3578 and any application specific purposes.
3580 The trust checking code now has a default behaviour: it will just
3581 check for an object with the same NID as the passed id. Functions can
3582 be provided to override either the default behaviour or the behaviour
3583 for a given id. SSL client, server and email already have functions
3584 in place for compatibility: they check the NID and also return "trusted"
3585 if the certificate is self signed.
3588 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
3589 traditional format into an EVP_PKEY structure.
3592 *) Add a password callback function PEM_cb() which either prompts for
3593 a password if usr_data is NULL or otherwise assumes it is a null
3594 terminated password. Allow passwords to be passed on command line
3595 environment or config files in a few more utilities.
3598 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
3599 keys. Add some short names for PKCS#8 PBE algorithms and allow them
3600 to be specified on the command line for the pkcs8 and pkcs12 utilities.
3601 Update documentation.
3604 *) Support for ASN1 "NULL" type. This could be handled before by using
3605 ASN1_TYPE but there wasn't any function that would try to read a NULL
3606 and produce an error if it couldn't. For compatibility we also have
3607 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
3608 don't allocate anything because they don't need to.
3611 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
3613 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
3615 *) Rebuild of the memory allocation routines used by OpenSSL code and
3616 possibly others as well. The purpose is to make an interface that
3617 provide hooks so anyone can build a separate set of allocation and
3618 deallocation routines to be used by OpenSSL, for example memory
3619 pool implementations, or something else, which was previously hard
3620 since Malloc(), Realloc() and Free() were defined as macros having
3621 the values malloc, realloc and free, respectively (except for Win32
3622 compilations). The same is provided for memory debugging code.
3623 OpenSSL already comes with functionality to find memory leaks, but
3624 this gives people a chance to debug other memory problems.
3626 With these changes, a new set of functions and macros have appeared:
3628 CRYPTO_set_mem_debug_functions() [F]
3629 CRYPTO_get_mem_debug_functions() [F]
3630 CRYPTO_dbg_set_options() [F]
3631 CRYPTO_dbg_get_options() [F]
3632 CRYPTO_malloc_debug_init() [M]
3634 The memory debug functions are NULL by default, unless the library
3635 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
3636 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
3637 gives the standard debugging functions that come with OpenSSL) or
3638 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
3639 provided by the library user) must be used. When the standard
3640 debugging functions are used, CRYPTO_dbg_set_options can be used to
3641 request additional information:
3642 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
3643 the CRYPTO_MDEBUG_xxx macro when compiling the library.
3645 Also, things like CRYPTO_set_mem_functions will always give the
3646 expected result (the new set of functions is used for allocation
3647 and deallocation) at all times, regardless of platform and compiler
3650 To finish it up, some functions that were never use in any other
3651 way than through macros have a new API and new semantic:
3654 CRYPTO_dbg_realloc()
3657 All macros of value have retained their old syntax.
3658 [Richard Levitte and Bodo Moeller]
3660 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
3661 ordering of SMIMECapabilities wasn't in "strength order" and there
3662 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
3666 *) Some ASN1 types with illegal zero length encoding (INTEGER,
3667 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
3668 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
3670 *) Merge in my S/MIME library for OpenSSL. This provides a simple
3671 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
3672 functionality to handle multipart/signed properly) and a utility
3673 called 'smime' to call all this stuff. This is based on code I
3674 originally wrote for Celo who have kindly allowed it to be
3675 included in OpenSSL.
3678 *) Add variants des_set_key_checked and des_set_key_unchecked of
3679 des_set_key (aka des_key_sched). Global variable des_check_key
3680 decides which of these is called by des_set_key; this way
3681 des_check_key behaves as it always did, but applications and
3682 the library itself, which was buggy for des_check_key == 1,
3683 have a cleaner way to pick the version they need.
3686 *) New function PKCS12_newpass() which changes the password of a
3690 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
3691 dynamic mix. In both cases the ids can be used as an index into the
3692 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
3693 functions so they accept a list of the field values and the
3694 application doesn't need to directly manipulate the X509_TRUST
3698 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
3702 *) Modify the way the V3 extension code looks up extensions. This now
3703 works in a similar way to the object code: we have some "standard"
3704 extensions in a static table which is searched with OBJ_bsearch()
3705 and the application can add dynamic ones if needed. The file
3706 crypto/x509v3/ext_dat.h now has the info: this file needs to be
3707 updated whenever a new extension is added to the core code and kept
3708 in ext_nid order. There is a simple program 'tabtest.c' which checks
3709 this. New extensions are not added too often so this file can readily
3710 be maintained manually.
3712 There are two big advantages in doing things this way. The extensions
3713 can be looked up immediately and no longer need to be "added" using
3714 X509V3_add_standard_extensions(): this function now does nothing.
3715 [Side note: I get *lots* of email saying the extension code doesn't
3716 work because people forget to call this function]
3717 Also no dynamic allocation is done unless new extensions are added:
3718 so if we don't add custom extensions there is no need to call
3719 X509V3_EXT_cleanup().
3722 *) Modify enc utility's salting as follows: make salting the default. Add a
3723 magic header, so unsalted files fail gracefully instead of just decrypting
3724 to garbage. This is because not salting is a big security hole, so people
3725 should be discouraged from doing it.
3728 *) Fixes and enhancements to the 'x509' utility. It allowed a message
3729 digest to be passed on the command line but it only used this
3730 parameter when signing a certificate. Modified so all relevant
3731 operations are affected by the digest parameter including the
3732 -fingerprint and -x509toreq options. Also -x509toreq choked if a
3733 DSA key was used because it didn't fix the digest.
3736 *) Initial certificate chain verify code. Currently tests the untrusted
3737 certificates for consistency with the verify purpose (which is set
3738 when the X509_STORE_CTX structure is set up) and checks the pathlength.
3740 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
3741 this is because it will reject chains with invalid extensions whereas
3742 every previous version of OpenSSL and SSLeay made no checks at all.
3744 Trust code: checks the root CA for the relevant trust settings. Trust
3745 settings have an initial value consistent with the verify purpose: e.g.
3746 if the verify purpose is for SSL client use it expects the CA to be
3747 trusted for SSL client use. However the default value can be changed to
3748 permit custom trust settings: one example of this would be to only trust
3749 certificates from a specific "secure" set of CAs.
3751 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
3752 which should be used for version portability: especially since the
3753 verify structure is likely to change more often now.
3755 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
3756 to set them. If not set then assume SSL clients will verify SSL servers
3759 Two new options to the verify program: -untrusted allows a set of
3760 untrusted certificates to be passed in and -purpose which sets the
3761 intended purpose of the certificate. If a purpose is set then the
3762 new chain verify code is used to check extension consistency.
3765 *) Support for the authority information access extension.
3768 *) Modify RSA and DSA PEM read routines to transparently handle
3769 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
3770 public keys in a format compatible with certificate
3771 SubjectPublicKeyInfo structures. Unfortunately there were already
3772 functions called *_PublicKey_* which used various odd formats so
3773 these are retained for compatibility: however the DSA variants were
3774 never in a public release so they have been deleted. Changed dsa/rsa
3775 utilities to handle the new format: note no releases ever handled public
3776 keys so we should be OK.
3778 The primary motivation for this change is to avoid the same fiasco
3779 that dogs private keys: there are several incompatible private key
3780 formats some of which are standard and some OpenSSL specific and
3781 require various evil hacks to allow partial transparent handling and
3782 even then it doesn't work with DER formats. Given the option anything
3783 other than PKCS#8 should be dumped: but the other formats have to
3784 stay in the name of compatibility.
3786 With public keys and the benefit of hindsight one standard format
3787 is used which works with EVP_PKEY, RSA or DSA structures: though
3788 it clearly returns an error if you try to read the wrong kind of key.
3790 Added a -pubkey option to the 'x509' utility to output the public key.
3791 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
3792 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
3793 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
3794 that do the same as the EVP_PKEY_assign_*() except they up the
3795 reference count of the added key (they don't "swallow" the
3799 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
3800 CRLs would fail if the file contained no certificates or no CRLs:
3801 added a new function to read in both types and return the number
3802 read: this means that if none are read it will be an error. The
3803 DER versions of the certificate and CRL reader would always fail
3804 because it isn't possible to mix certificates and CRLs in DER format
3805 without choking one or the other routine. Changed this to just read
3806 a certificate: this is the best we can do. Also modified the code
3807 in apps/verify.c to take notice of return codes: it was previously
3808 attempting to read in certificates from NULL pointers and ignoring
3809 any errors: this is one reason why the cert and CRL reader seemed
3810 to work. It doesn't check return codes from the default certificate
3811 routines: these may well fail if the certificates aren't installed.
3814 *) Code to support otherName option in GeneralName.
3817 *) First update to verify code. Change the verify utility
3818 so it warns if it is passed a self signed certificate:
3819 for consistency with the normal behaviour. X509_verify
3820 has been modified to it will now verify a self signed
3821 certificate if *exactly* the same certificate appears
3822 in the store: it was previously impossible to trust a
3823 single self signed certificate. This means that:
3824 openssl verify ss.pem
3825 now gives a warning about a self signed certificate but
3826 openssl verify -CAfile ss.pem ss.pem
3830 *) For servers, store verify_result in SSL_SESSION data structure
3831 (and add it to external session representation).
3832 This is needed when client certificate verifications fails,
3833 but an application-provided verification callback (set by
3834 SSL_CTX_set_cert_verify_callback) allows accepting the session
3835 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
3836 but returns 1): When the session is reused, we have to set
3837 ssl->verify_result to the appropriate error code to avoid
3839 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
3841 *) Fix a bug in the new PKCS#7 code: it didn't consider the
3842 case in PKCS7_dataInit() where the signed PKCS7 structure
3843 didn't contain any existing data because it was being created.
3844 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
3846 *) Add a salt to the key derivation routines in enc.c. This
3847 forms the first 8 bytes of the encrypted file. Also add a
3848 -S option to allow a salt to be input on the command line.
3851 *) New function X509_cmp(). Oddly enough there wasn't a function
3852 to compare two certificates. We do this by working out the SHA1
3853 hash and comparing that. X509_cmp() will be needed by the trust
3857 *) SSL_get1_session() is like SSL_get_session(), but increments
3858 the reference count in the SSL_SESSION returned.
3859 [Geoff Thorpe <geoff@eu.c2.net>]
3861 *) Fix for 'req': it was adding a null to request attributes.
3862 Also change the X509_LOOKUP and X509_INFO code to handle
3863 certificate auxiliary information.
3866 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
3870 *) Add the possibility to add extra information to the memory leak
3871 detecting output, to form tracebacks, showing from where each
3872 allocation was originated: CRYPTO_push_info("constant string") adds
3873 the string plus current file name and line number to a per-thread
3874 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
3875 is like calling CYRPTO_pop_info() until the stack is empty.
3876 Also updated memory leak detection code to be multi-thread-safe.
3879 *) Add options -text and -noout to pkcs7 utility and delete the
3880 encryption options which never did anything. Update docs.
3883 *) Add options to some of the utilities to allow the pass phrase
3884 to be included on either the command line (not recommended on
3885 OSes like Unix) or read from the environment. Update the
3886 manpages and fix a few bugs.
3889 *) Add a few manpages for some of the openssl commands.
3892 *) Fix the -revoke option in ca. It was freeing up memory twice,
3893 leaking and not finding already revoked certificates.
3896 *) Extensive changes to support certificate auxiliary information.
3897 This involves the use of X509_CERT_AUX structure and X509_AUX
3898 functions. An X509_AUX function such as PEM_read_X509_AUX()
3899 can still read in a certificate file in the usual way but it
3900 will also read in any additional "auxiliary information". By
3901 doing things this way a fair degree of compatibility can be
3902 retained: existing certificates can have this information added
3903 using the new 'x509' options.
3905 Current auxiliary information includes an "alias" and some trust
3906 settings. The trust settings will ultimately be used in enhanced
3907 certificate chain verification routines: currently a certificate
3908 can only be trusted if it is self signed and then it is trusted
3912 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
3913 The problem was that one of the replacement routines had not been working
3914 since SSLeay releases. For now the offending routine has been replaced
3915 with non-optimised assembler. Even so, this now gives around 95%
3916 performance improvement for 1024 bit RSA signs.
3919 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
3920 handling. Most clients have the effective key size in bits equal to
3921 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
3922 A few however don't do this and instead use the size of the decrypted key
3923 to determine the RC2 key length and the AlgorithmIdentifier to determine
3924 the effective key length. In this case the effective key length can still
3925 be 40 bits but the key length can be 168 bits for example. This is fixed
3926 by manually forcing an RC2 key into the EVP_PKEY structure because the
3927 EVP code can't currently handle unusual RC2 key sizes: it always assumes
3928 the key length and effective key length are equal.
3931 *) Add a bunch of functions that should simplify the creation of
3932 X509_NAME structures. Now you should be able to do:
3933 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
3934 and have it automatically work out the correct field type and fill in
3935 the structures. The more adventurous can try:
3936 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
3937 and it will (hopefully) work out the correct multibyte encoding.
3940 *) Change the 'req' utility to use the new field handling and multibyte
3941 copy routines. Before the DN field creation was handled in an ad hoc
3942 way in req, ca, and x509 which was rather broken and didn't support
3943 BMPStrings or UTF8Strings. Since some software doesn't implement
3944 BMPStrings or UTF8Strings yet, they can be enabled using the config file
3945 using the dirstring_type option. See the new comment in the default
3946 openssl.cnf for more info.
3949 *) Make crypto/rand/md_rand.c more robust:
3950 - Assure unique random numbers after fork().
3951 - Make sure that concurrent threads access the global counter and
3952 md serializably so that we never lose entropy in them
3953 or use exactly the same state in multiple threads.
3954 Access to the large state is not always serializable because
3955 the additional locking could be a performance killer, and
3956 md should be large enough anyway.
3959 *) New file apps/app_rand.c with commonly needed functionality
3960 for handling the random seed file.
3962 Use the random seed file in some applications that previously did not:
3964 dsaparam -genkey (which also ignored its '-rand' option),
3967 x509 (when signing).
3968 Except on systems with /dev/urandom, it is crucial to have a random
3969 seed file at least for key creation, DSA signing, and for DH exchanges;
3970 for RSA signatures we could do without one.
3972 gendh and gendsa (unlike genrsa) used to read only the first byte
3973 of each file listed in the '-rand' option. The function as previously
3974 found in genrsa is now in app_rand.c and is used by all programs
3975 that support '-rand'.
3978 *) In RAND_write_file, use mode 0600 for creating files;
3979 don't just chmod when it may be too late.
3982 *) Report an error from X509_STORE_load_locations
3983 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
3986 *) New function ASN1_mbstring_copy() this copies a string in either
3987 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
3988 into an ASN1_STRING type. A mask of permissible types is passed
3989 and it chooses the "minimal" type to use or an error if not type
3993 *) Add function equivalents to the various macros in asn1.h. The old
3994 macros are retained with an M_ prefix. Code inside the library can
3995 use the M_ macros. External code (including the openssl utility)
3996 should *NOT* in order to be "shared library friendly".
3999 *) Add various functions that can check a certificate's extensions
4000 to see if it usable for various purposes such as SSL client,
4001 server or S/MIME and CAs of these types. This is currently
4002 VERY EXPERIMENTAL but will ultimately be used for certificate chain
4003 verification. Also added a -purpose flag to x509 utility to
4004 print out all the purposes.
4007 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
4011 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
4012 for, obtain and decode and extension and obtain its critical flag.
4013 This allows all the necessary extension code to be handled in a
4014 single function call.
4017 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
4018 platforms. See crypto/rc4/rc4_enc.c for further details.
4021 *) New -noout option to asn1parse. This causes no output to be produced
4022 its main use is when combined with -strparse and -out to extract data
4023 from a file (which may not be in ASN.1 format).
4026 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
4027 when producing the local key id.
4028 [Richard Levitte <levitte@stacken.kth.se>]
4030 *) New option -dhparam in s_server. This allows a DH parameter file to be
4031 stated explicitly. If it is not stated then it tries the first server
4032 certificate file. The previous behaviour hard coded the filename
4036 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
4037 a public key to be input or output. For example:
4038 openssl rsa -in key.pem -pubout -out pubkey.pem
4039 Also added necessary DSA public key functions to handle this.
4042 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
4043 in the message. This was handled by allowing
4044 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
4045 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
4047 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
4048 to the end of the strings whereas this didn't. This would cause problems
4049 if strings read with d2i_ASN1_bytes() were later modified.
4050 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
4052 *) Fix for base64 decode bug. When a base64 bio reads only one line of
4053 data and it contains EOF it will end up returning an error. This is
4054 caused by input 46 bytes long. The cause is due to the way base64
4055 BIOs find the start of base64 encoded data. They do this by trying a
4056 trial decode on each line until they find one that works. When they
4057 do a flag is set and it starts again knowing it can pass all the
4058 data directly through the decoder. Unfortunately it doesn't reset
4059 the context it uses. This means that if EOF is reached an attempt
4060 is made to pass two EOFs through the context and this causes the
4061 resulting error. This can also cause other problems as well. As is
4062 usual with these problems it takes *ages* to find and the fix is
4063 trivial: move one line.
4064 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
4066 *) Ugly workaround to get s_client and s_server working under Windows. The
4067 old code wouldn't work because it needed to select() on sockets and the
4068 tty (for keypresses and to see if data could be written). Win32 only
4069 supports select() on sockets so we select() with a 1s timeout on the
4070 sockets and then see if any characters are waiting to be read, if none
4071 are present then we retry, we also assume we can always write data to
4072 the tty. This isn't nice because the code then blocks until we've
4073 received a complete line of data and it is effectively polling the
4074 keyboard at 1s intervals: however it's quite a bit better than not
4075 working at all :-) A dedicated Windows application might handle this
4076 with an event loop for example.
4079 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
4080 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
4081 will be called when RSA_sign() and RSA_verify() are used. This is useful
4082 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
4083 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
4084 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
4085 This necessitated the support of an extra signature type NID_md5_sha1
4086 for SSL signatures and modifications to the SSL library to use it instead
4087 of calling RSA_public_decrypt() and RSA_private_encrypt().
4090 *) Add new -verify -CAfile and -CApath options to the crl program, these
4091 will lookup a CRL issuers certificate and verify the signature in a
4092 similar way to the verify program. Tidy up the crl program so it
4093 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
4094 less strict. It will now permit CRL extensions even if it is not
4095 a V2 CRL: this will allow it to tolerate some broken CRLs.
4098 *) Initialize all non-automatic variables each time one of the openssl
4099 sub-programs is started (this is necessary as they may be started
4100 multiple times from the "OpenSSL>" prompt).
4101 [Lennart Bang, Bodo Moeller]
4103 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
4104 removing all other RSA functionality (this is what NO_RSA does). This
4105 is so (for example) those in the US can disable those operations covered
4106 by the RSA patent while allowing storage and parsing of RSA keys and RSA
4110 *) Non-copying interface to BIO pairs.
4111 (still largely untested)
4114 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
4115 ASCII string. This was handled independently in various places before.
4118 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
4119 UTF8 strings a character at a time.
4122 *) Use client_version from client hello to select the protocol
4123 (s23_srvr.c) and for RSA client key exchange verification
4124 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
4127 *) Add various utility functions to handle SPKACs, these were previously
4128 handled by poking round in the structure internals. Added new function
4129 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
4130 print, verify and generate SPKACs. Based on an original idea from
4131 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
4134 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
4137 *) Allow the config file extension section to be overwritten on the
4138 command line. Based on an original idea from Massimiliano Pala
4139 <madwolf@comune.modena.it>. The new option is called -extensions
4140 and can be applied to ca, req and x509. Also -reqexts to override
4141 the request extensions in req and -crlexts to override the crl extensions
4145 *) Add new feature to the SPKAC handling in ca. Now you can include
4146 the same field multiple times by preceding it by "XXXX." for example:
4149 this is the same syntax as used in the req config file.
4152 *) Allow certificate extensions to be added to certificate requests. These
4153 are specified in a 'req_extensions' option of the req section of the
4154 config file. They can be printed out with the -text option to req but
4155 are otherwise ignored at present.
4158 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
4159 data read consists of only the final block it would not decrypted because
4160 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
4161 A misplaced 'break' also meant the decrypted final block might not be
4162 copied until the next read.
4165 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
4166 a few extra parameters to the DH structure: these will be useful if
4167 for example we want the value of 'q' or implement X9.42 DH.
4170 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
4171 provides hooks that allow the default DSA functions or functions on a
4172 "per key" basis to be replaced. This allows hardware acceleration and
4173 hardware key storage to be handled without major modification to the
4174 library. Also added low level modexp hooks and CRYPTO_EX structure and
4175 associated functions.
4178 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
4179 as "read only": it can't be written to and the buffer it points to will
4180 not be freed. Reading from a read only BIO is much more efficient than
4181 a normal memory BIO. This was added because there are several times when
4182 an area of memory needs to be read from a BIO. The previous method was
4183 to create a memory BIO and write the data to it, this results in two
4184 copies of the data and an O(n^2) reading algorithm. There is a new
4185 function BIO_new_mem_buf() which creates a read only memory BIO from
4186 an area of memory. Also modified the PKCS#7 routines to use read only
4190 *) Bugfix: ssl23_get_client_hello did not work properly when called in
4191 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
4192 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
4193 but a retry condition occured while trying to read the rest.
4196 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
4197 NID_pkcs7_encrypted by default: this was wrong since this should almost
4198 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
4199 the encrypted data type: this is a more sensible place to put it and it
4200 allows the PKCS#12 code to be tidied up that duplicated this
4204 *) Changed obj_dat.pl script so it takes its input and output files on
4205 the command line. This should avoid shell escape redirection problems
4209 *) Initial support for certificate extension requests, these are included
4210 in things like Xenroll certificate requests. Included functions to allow
4211 extensions to be obtained and added.
4214 *) -crlf option to s_client and s_server for sending newlines as
4215 CRLF (as required by many protocols).
4218 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
4220 *) Install libRSAglue.a when OpenSSL is built with RSAref.
4221 [Ralf S. Engelschall]
4223 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
4224 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
4226 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
4230 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
4231 DH parameters/keys (q is lost during that conversion, but the resulting
4232 DH parameters contain its length).
4234 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
4235 much faster than DH_generate_parameters (which creates parameters
4236 where p = 2*q + 1), and also the smaller q makes DH computations
4237 much more efficient (160-bit exponentiation instead of 1024-bit
4238 exponentiation); so this provides a convenient way to support DHE
4239 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
4240 utter importance to use
4241 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
4243 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
4244 when such DH parameters are used, because otherwise small subgroup
4245 attacks may become possible!
4248 *) Avoid memory leak in i2d_DHparams.
4251 *) Allow the -k option to be used more than once in the enc program:
4252 this allows the same encrypted message to be read by multiple recipients.
4255 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
4256 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
4257 it will always use the numerical form of the OID, even if it has a short
4261 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
4262 method only got called if p,q,dmp1,dmq1,iqmp components were present,
4263 otherwise bn_mod_exp was called. In the case of hardware keys for example
4264 no private key components need be present and it might store extra data
4265 in the RSA structure, which cannot be accessed from bn_mod_exp.
4266 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
4267 private key operations.
4270 *) Added support for SPARC Linux.
4273 *) pem_password_cb function type incompatibly changed from
4274 typedef int pem_password_cb(char *buf, int size, int rwflag);
4276 ....(char *buf, int size, int rwflag, void *userdata);
4277 so that applications can pass data to their callbacks:
4278 The PEM[_ASN1]_{read,write}... functions and macros now take an
4279 additional void * argument, which is just handed through whenever
4280 the password callback is called.
4281 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
4283 New function SSL_CTX_set_default_passwd_cb_userdata.
4285 Compatibility note: As many C implementations push function arguments
4286 onto the stack in reverse order, the new library version is likely to
4287 interoperate with programs that have been compiled with the old
4288 pem_password_cb definition (PEM_whatever takes some data that
4289 happens to be on the stack as its last argument, and the callback
4290 just ignores this garbage); but there is no guarantee whatsoever that
4293 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
4294 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
4295 problems not only on Windows, but also on some Unix platforms.
4296 To avoid problematic command lines, these definitions are now in an
4297 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
4298 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
4301 *) MIPS III/IV assembler module is reimplemented.
4304 *) More DES library cleanups: remove references to srand/rand and
4305 delete an unused file.
4308 *) Add support for the the free Netwide assembler (NASM) under Win32,
4309 since not many people have MASM (ml) and it can be hard to obtain.
4310 This is currently experimental but it seems to work OK and pass all
4311 the tests. Check out INSTALL.W32 for info.
4314 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
4315 without temporary keys kept an extra copy of the server key,
4316 and connections with temporary keys did not free everything in case
4320 *) New function RSA_check_key and new openssl rsa option -check
4321 for verifying the consistency of RSA keys.
4322 [Ulf Moeller, Bodo Moeller]
4324 *) Various changes to make Win32 compile work:
4325 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
4326 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
4327 comparison" warnings.
4328 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
4331 *) Add a debugging option to PKCS#5 v2 key generation function: when
4332 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
4333 derived keys are printed to stderr.
4336 *) Copy the flags in ASN1_STRING_dup().
4337 [Roman E. Pavlov <pre@mo.msk.ru>]
4339 *) The x509 application mishandled signing requests containing DSA
4340 keys when the signing key was also DSA and the parameters didn't match.
4342 It was supposed to omit the parameters when they matched the signing key:
4343 the verifying software was then supposed to automatically use the CA's
4344 parameters if they were absent from the end user certificate.
4346 Omitting parameters is no longer recommended. The test was also
4347 the wrong way round! This was probably due to unusual behaviour in
4348 EVP_cmp_parameters() which returns 1 if the parameters match.
4349 This meant that parameters were omitted when they *didn't* match and
4350 the certificate was useless. Certificates signed with 'ca' didn't have
4352 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
4354 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
4355 The interface is as follows:
4356 Applications can use
4357 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
4358 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
4359 "off" is now the default.
4360 The library internally uses
4361 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
4362 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
4363 to disable memory-checking temporarily.
4365 Some inconsistent states that previously were possible (and were
4366 even the default) are now avoided.
4368 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
4369 with each memory chunk allocated; this is occasionally more helpful
4370 than just having a counter.
4372 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
4374 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
4378 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
4379 which largely parallels "options", but is for changing API behaviour,
4380 whereas "options" are about protocol behaviour.
4381 Initial "mode" flags are:
4383 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
4384 a single record has been written.
4385 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
4386 retries use the same buffer location.
4387 (But all of the contents must be
4391 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
4394 *) Fix problems with no-hmac etc.
4395 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
4397 *) New functions RSA_get_default_method(), RSA_set_method() and
4398 RSA_get_method(). These allows replacement of RSA_METHODs without having
4399 to mess around with the internals of an RSA structure.
4402 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
4403 Also really enable memory leak checks in openssl.c and in some
4405 [Chad C. Mulligan, Bodo Moeller]
4407 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
4408 up the length of negative integers. This has now been simplified to just
4409 store the length when it is first determined and use it later, rather
4410 than trying to keep track of where data is copied and updating it to
4412 [Steve Henson, reported by Brien Wheeler
4413 <bwheeler@authentica-security.com>]
4415 *) Add a new function PKCS7_signatureVerify. This allows the verification
4416 of a PKCS#7 signature but with the signing certificate passed to the
4417 function itself. This contrasts with PKCS7_dataVerify which assumes the
4418 certificate is present in the PKCS#7 structure. This isn't always the
4419 case: certificates can be omitted from a PKCS#7 structure and be
4420 distributed by "out of band" means (such as a certificate database).
4423 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
4424 function prototypes in pem.h, also change util/mkdef.pl to add the
4425 necessary function names.
4428 *) mk1mf.pl (used by Windows builds) did not properly read the
4429 options set by Configure in the top level Makefile, and Configure
4430 was not even able to write more than one option correctly.
4431 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
4434 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
4435 file to be loaded from a BIO or FILE pointer. The BIO version will
4436 for example allow memory BIOs to contain config info.
4439 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
4440 Whoever hopes to achieve shared-library compatibility across versions
4441 must use this, not the compile-time macro.
4442 (Exercise 0.9.4: Which is the minimum library version required by
4444 Note: All this applies only to multi-threaded programs, others don't
4448 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
4449 through a BIO pair triggered the default case, i.e.
4450 SSLerr(...,SSL_R_UNKNOWN_STATE).
4453 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
4454 can use the SSL library even if none of the specific BIOs is
4458 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
4459 for the encoded length.
4460 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
4462 *) Add initial documentation of the X509V3 functions.
4465 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
4466 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
4467 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
4468 secure PKCS#8 private key format with a high iteration count.
4471 *) Fix determination of Perl interpreter: A perl or perl5
4472 _directory_ in $PATH was also accepted as the interpreter.
4473 [Ralf S. Engelschall]
4475 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
4476 wrong with it but it was very old and did things like calling
4477 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
4481 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
4482 to use the new extension code.
4485 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
4486 with macros. This should make it easier to change their form, add extra
4487 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
4491 *) Add to configuration table a new entry that can specify an alternative
4492 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
4493 according to Mark Crispin <MRC@Panda.COM>.
4497 *) DES CBC did not update the IV. Weird.
4500 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
4501 Changing the behaviour of the former might break existing programs --
4502 where IV updating is needed, des_ncbc_encrypt can be used.
4505 *) When bntest is run from "make test" it drives bc to check its
4506 calculations, as well as internally checking them. If an internal check
4507 fails, it needs to cause bc to give a non-zero result or make test carries
4508 on without noticing the failure. Fixed.
4511 *) DES library cleanups.
4514 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
4515 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
4516 ciphers. NOTE: although the key derivation function has been verified
4517 against some published test vectors it has not been extensively tested
4518 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
4522 *) Instead of "mkdir -p", which is not fully portable, use new
4523 Perl script "util/mkdir-p.pl".
4526 *) Rewrite the way password based encryption (PBE) is handled. It used to
4527 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
4528 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
4529 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
4530 the 'parameter' field of the AlgorithmIdentifier is passed to the
4531 underlying key generation function so it must do its own ASN1 parsing.
4532 This has also changed the EVP_PBE_CipherInit() function which now has a
4533 'parameter' argument instead of literal salt and iteration count values
4534 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
4537 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
4538 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
4539 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
4540 KEY" because this clashed with PKCS#8 unencrypted string. Since this
4541 value was just used as a "magic string" and not used directly its
4542 value doesn't matter.
4545 *) Introduce some semblance of const correctness to BN. Shame C doesn't
4549 *) "linux-sparc64" configuration (ultrapenguin).
4550 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
4551 "linux-sparc" configuration.
4552 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
4554 *) config now generates no-xxx options for missing ciphers.
4557 *) Support the EBCDIC character set (work in progress).
4558 File ebcdic.c not yet included because it has a different license.
4559 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4561 *) Support BS2000/OSD-POSIX.
4562 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4564 *) Make callbacks for key generation use void * instead of char *.
4567 *) Make S/MIME samples compile (not yet tested).
4570 *) Additional typesafe stacks.
4573 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
4577 Changes between 0.9.3 and 0.9.3a [29 May 1999]
4579 *) New configuration variant "sco5-gcc".
4581 *) Updated some demos.
4582 [Sean O Riordain, Wade Scholine]
4584 *) Add missing BIO_free at exit of pkcs12 application.
4587 *) Fix memory leak in conf.c.
4590 *) Updates for Win32 to assembler version of MD5.
4593 *) Set #! path to perl in apps/der_chop to where we found it
4594 instead of using a fixed path.
4597 *) SHA library changes for irix64-mips4-cc.
4600 *) Improvements for VMS support.
4604 Changes between 0.9.2b and 0.9.3 [24 May 1999]
4606 *) Bignum library bug fix. IRIX 6 passes "make test" now!
4607 This also avoids the problems with SC4.2 and unpatched SC5.
4608 [Andy Polyakov <appro@fy.chalmers.se>]
4610 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
4611 These are required because of the typesafe stack would otherwise break
4612 existing code. If old code used a structure member which used to be STACK
4613 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
4614 sk_num or sk_value it would produce an error because the num, data members
4615 are not present in STACK_OF. Now it just produces a warning. sk_set
4616 replaces the old method of assigning a value to sk_value
4617 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
4618 that does this will no longer work (and should use sk_set instead) but
4619 this could be regarded as a "questionable" behaviour anyway.
4622 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
4623 correctly handle encrypted S/MIME data.
4626 *) Change type of various DES function arguments from des_cblock
4627 (which means, in function argument declarations, pointer to char)
4628 to des_cblock * (meaning pointer to array with 8 char elements),
4629 which allows the compiler to do more typechecking; it was like
4630 that back in SSLeay, but with lots of ugly casts.
4632 Introduce new type const_des_cblock.
4635 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
4636 problems: find RecipientInfo structure that matches recipient certificate
4637 and initialise the ASN1 structures properly based on passed cipher.
4640 *) Belatedly make the BN tests actually check the results.
4643 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
4644 to and from BNs: it was completely broken. New compilation option
4645 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
4646 key elements as negative integers.
4649 *) Reorganize and speed up MD5.
4650 [Andy Polyakov <appro@fy.chalmers.se>]
4653 [Richard Levitte <richard@levitte.org>]
4655 *) New option -out to asn1parse to allow the parsed structure to be
4656 output to a file. This is most useful when combined with the -strparse
4657 option to examine the output of things like OCTET STRINGS.
4660 *) Make SSL library a little more fool-proof by not requiring any longer
4661 that SSL_set_{accept,connect}_state be called before
4662 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
4663 in many applications because usually everything *appeared* to work as
4664 intended anyway -- now it really works as intended).
4667 *) Move openssl.cnf out of lib/.
4670 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
4671 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
4672 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
4673 [Ralf S. Engelschall]
4675 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
4676 handle PKCS#7 enveloped data properly.
4677 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
4679 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
4680 copying pointers. The cert_st handling is changed by this in
4681 various ways (and thus what used to be known as ctx->default_cert
4682 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
4683 any longer when s->cert does not give us what we need).
4684 ssl_cert_instantiate becomes obsolete by this change.
4685 As soon as we've got the new code right (possibly it already is?),
4686 we have solved a couple of bugs of the earlier code where s->cert
4687 was used as if it could not have been shared with other SSL structures.
4689 Note that using the SSL API in certain dirty ways now will result
4690 in different behaviour than observed with earlier library versions:
4691 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
4692 does not influence s as it used to.
4694 In order to clean up things more thoroughly, inside SSL_SESSION
4695 we don't use CERT any longer, but a new structure SESS_CERT
4696 that holds per-session data (if available); currently, this is
4697 the peer's certificate chain and, for clients, the server's certificate
4698 and temporary key. CERT holds only those values that can have
4699 meaningful defaults in an SSL_CTX.
4702 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
4703 from the internal representation. Various PKCS#7 fixes: remove some
4704 evil casts and set the enc_dig_alg field properly based on the signing
4708 *) Allow PKCS#12 password to be set from the command line or the
4709 environment. Let 'ca' get its config file name from the environment
4710 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
4714 *) Allow certificate policies extension to use an IA5STRING for the
4715 organization field. This is contrary to the PKIX definition but
4716 VeriSign uses it and IE5 only recognises this form. Document 'x509'
4720 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
4721 without disallowing inline assembler and the like for non-pedantic builds.
4724 *) Support Borland C++ builder.
4725 [Janez Jere <jj@void.si>, modified by Ulf Möller]
4730 *) SHA-1 cleanups and performance enhancements.
4731 [Andy Polyakov <appro@fy.chalmers.se>]
4733 *) Sparc v8plus assembler for the bignum library.
4734 [Andy Polyakov <appro@fy.chalmers.se>]
4736 *) Accept any -xxx and +xxx compiler options in Configure.
4739 *) Update HPUX configuration.
4742 *) Add missing sk_<type>_unshift() function to safestack.h
4743 [Ralf S. Engelschall]
4745 *) New function SSL_CTX_use_certificate_chain_file that sets the
4746 "extra_cert"s in addition to the certificate. (This makes sense
4747 only for "PEM" format files, as chains as a whole are not
4751 *) Support verify_depth from the SSL API.
4752 x509_vfy.c had what can be considered an off-by-one-error:
4753 Its depth (which was not part of the external interface)
4754 was actually counting the number of certificates in a chain;
4755 now it really counts the depth.
4758 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
4759 instead of X509err, which often resulted in confusing error
4760 messages since the error codes are not globally unique
4761 (e.g. an alleged error in ssl3_accept when a certificate
4762 didn't match the private key).
4764 *) New function SSL_CTX_set_session_id_context that allows to set a default
4765 value (so that you don't need SSL_set_session_id_context for each
4766 connection using the SSL_CTX).
4769 *) OAEP decoding bug fix.
4772 *) Support INSTALL_PREFIX for package builders, as proposed by
4776 *) New Configure options "threads" and "no-threads". For systems
4777 where the proper compiler options are known (currently Solaris
4778 and Linux), "threads" is the default.
4781 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
4784 *) Install various scripts to $(OPENSSLDIR)/misc, not to
4785 $(INSTALLTOP)/bin -- they shouldn't clutter directories
4786 such as /usr/local/bin.
4789 *) "make linux-shared" to build shared libraries.
4790 [Niels Poppe <niels@netbox.org>]
4792 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
4795 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
4796 extension adding in x509 utility.
4799 *) Remove NOPROTO sections and error code comments.
4802 *) Partial rewrite of the DEF file generator to now parse the ANSI
4806 *) New Configure options --prefix=DIR and --openssldir=DIR.
4809 *) Complete rewrite of the error code script(s). It is all now handled
4810 by one script at the top level which handles error code gathering,
4811 header rewriting and C source file generation. It should be much better
4812 than the old method: it now uses a modified version of Ulf's parser to
4813 read the ANSI prototypes in all header files (thus the old K&R definitions
4814 aren't needed for error creation any more) and do a better job of
4815 translating function codes into names. The old 'ASN1 error code imbedded
4816 in a comment' is no longer necessary and it doesn't use .err files which
4817 have now been deleted. Also the error code call doesn't have to appear all
4818 on one line (which resulted in some large lines...).
4821 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
4824 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
4825 0 (which usually indicates a closed connection), but continue reading.
4828 *) Fix some race conditions.
4831 *) Add support for CRL distribution points extension. Add Certificate
4832 Policies and CRL distribution points documentation.
4835 *) Move the autogenerated header file parts to crypto/opensslconf.h.
4838 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
4839 8 of keying material. Merlin has also confirmed interop with this fix
4840 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
4841 [Merlin Hughes <merlin@baltimore.ie>]
4843 *) Fix lots of warnings.
4844 [Richard Levitte <levitte@stacken.kth.se>]
4846 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
4847 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
4848 [Richard Levitte <levitte@stacken.kth.se>]
4850 *) Fix problems with sizeof(long) == 8.
4851 [Andy Polyakov <appro@fy.chalmers.se>]
4853 *) Change functions to ANSI C.
4856 *) Fix typos in error codes.
4857 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
4859 *) Remove defunct assembler files from Configure.
4862 *) SPARC v8 assembler BIGNUM implementation.
4863 [Andy Polyakov <appro@fy.chalmers.se>]
4865 *) Support for Certificate Policies extension: both print and set.
4866 Various additions to support the r2i method this uses.
4869 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
4870 return a const string when you are expecting an allocated buffer.
4873 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
4874 types DirectoryString and DisplayText.
4877 *) Add code to allow r2i extensions to access the configuration database,
4878 add an LHASH database driver and add several ctx helper functions.
4881 *) Fix an evil bug in bn_expand2() which caused various BN functions to
4882 fail when they extended the size of a BIGNUM.
4885 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
4886 support typesafe stack.
4889 *) Fix typo in SSL_[gs]et_options().
4890 [Nils Frostberg <nils@medcom.se>]
4892 *) Delete various functions and files that belonged to the (now obsolete)
4893 old X509V3 handling code.
4896 *) New Configure option "rsaref".
4899 *) Don't auto-generate pem.h.
4902 *) Introduce type-safe ASN.1 SETs.
4905 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
4906 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
4908 *) Introduce type-safe STACKs. This will almost certainly break lots of code
4909 that links with OpenSSL (well at least cause lots of warnings), but fear
4910 not: the conversion is trivial, and it eliminates loads of evil casts. A
4911 few STACKed things have been converted already. Feel free to convert more.
4912 In the fullness of time, I'll do away with the STACK type altogether.
4915 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
4916 specified in <certfile> by updating the entry in the index.txt file.
4917 This way one no longer has to edit the index.txt file manually for
4918 revoking a certificate. The -revoke option does the gory details now.
4919 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
4921 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
4922 `-text' option at all and this way the `-noout -text' combination was
4923 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
4924 [Ralf S. Engelschall]
4926 *) Make sure a corresponding plain text error message exists for the
4927 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
4928 verify callback function determined that a certificate was revoked.
4929 [Ralf S. Engelschall]
4931 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
4932 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
4933 all available cipers including rc5, which was forgotten until now.
4934 In order to let the testing shell script know which algorithms
4935 are available, a new (up to now undocumented) command
4936 "openssl list-cipher-commands" is used.
4939 *) Bugfix: s_client occasionally would sleep in select() when
4940 it should have checked SSL_pending() first.
4943 *) New functions DSA_do_sign and DSA_do_verify to provide access to
4944 the raw DSA values prior to ASN.1 encoding.
4947 *) Tweaks to Configure
4948 [Niels Poppe <niels@netbox.org>]
4950 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
4954 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
4957 *) New config option to avoid instructions that are illegal on the 80386.
4958 The default code is faster, but requires at least a 486.
4961 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
4962 SSL2_SERVER_VERSION (not used at all) macros, which are now the
4963 same as SSL2_VERSION anyway.
4966 *) New "-showcerts" option for s_client.
4969 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
4970 application. Various cleanups and fixes.
4973 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
4974 modify error routines to work internally. Add error codes and PBE init
4975 to library startup routines.
4978 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
4979 packing functions to asn1 and evp. Changed function names and error
4980 codes along the way.
4983 *) PKCS12 integration: and so it begins... First of several patches to
4984 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
4985 objects to objects.h
4988 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
4989 and display support for Thawte strong extranet extension.
4992 *) Add LinuxPPC support.
4993 [Jeff Dubrule <igor@pobox.org>]
4995 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
4996 bn_div_words in alpha.s.
4997 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
4999 *) Make sure the RSA OAEP test is skipped under -DRSAref because
5000 OAEP isn't supported when OpenSSL is built with RSAref.
5001 [Ulf Moeller <ulf@fitug.de>]
5003 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
5004 so they no longer are missing under -DNOPROTO.
5005 [Soren S. Jorvang <soren@t.dk>]
5008 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
5010 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
5011 doesn't work when the session is reused. Coming soon!
5014 *) Fix a security hole, that allows sessions to be reused in the wrong
5015 context thus bypassing client cert protection! All software that uses
5016 client certs and session caches in multiple contexts NEEDS PATCHING to
5017 allow session reuse! A fuller solution is in the works.
5018 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
5020 *) Some more source tree cleanups (removed obsolete files
5021 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
5022 permission on "config" script to be executable) and a fix for the INSTALL
5024 [Ulf Moeller <ulf@fitug.de>]
5026 *) Remove some legacy and erroneous uses of malloc, free instead of
5028 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
5030 *) Make rsa_oaep_test return non-zero on error.
5031 [Ulf Moeller <ulf@fitug.de>]
5033 *) Add support for native Solaris shared libraries. Configure
5034 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
5035 if someone would make that last step automatic.
5036 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
5038 *) ctx_size was not built with the right compiler during "make links". Fixed.
5041 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
5042 except NULL ciphers". This means the default cipher list will no longer
5043 enable NULL ciphers. They need to be specifically enabled e.g. with
5044 the string "DEFAULT:eNULL".
5047 *) Fix to RSA private encryption routines: if p < q then it would
5048 occasionally produce an invalid result. This will only happen with
5049 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
5052 *) Be less restrictive and allow also `perl util/perlpath.pl
5053 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
5054 because this way one can also use an interpreter named `perl5' (which is
5055 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
5056 installed as `perl').
5057 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5059 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
5060 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5062 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
5063 advapi32.lib to Win32 build and change the pem test comparision
5064 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
5065 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
5066 and crypto/des/ede_cbcm_enc.c.
5069 *) DES quad checksum was broken on big-endian architectures. Fixed.
5072 *) Comment out two functions in bio.h that aren't implemented. Fix up the
5073 Win32 test batch file so it (might) work again. The Win32 test batch file
5074 is horrible: I feel ill....
5077 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
5078 in e_os.h. Audit of header files to check ANSI and non ANSI
5079 sections: 10 functions were absent from non ANSI section and not exported
5080 from Windows DLLs. Fixed up libeay.num for new functions.
5083 *) Make `openssl version' output lines consistent.
5084 [Ralf S. Engelschall]
5086 *) Fix Win32 symbol export lists for BIO functions: Added
5087 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
5088 to ms/libeay{16,32}.def.
5089 [Ralf S. Engelschall]
5091 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
5092 fine under Unix and passes some trivial tests I've now added. But the
5093 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
5094 added to make sure no one expects that this stuff really works in the
5095 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
5096 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
5098 [Ralf S. Engelschall]
5100 *) Fix the generation of two part addresses in perl.
5101 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
5103 *) Add config entry for Linux on MIPS.
5104 [John Tobey <jtobey@channel1.com>]
5106 *) Make links whenever Configure is run, unless we are on Windoze.
5109 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
5110 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
5114 *) Add a useful kludge to allow package maintainers to specify compiler and
5115 other platforms details on the command line without having to patch the
5116 Configure script everytime: One now can use ``perl Configure
5117 <id>:<details>'', i.e. platform ids are allowed to have details appended
5118 to them (seperated by colons). This is treated as there would be a static
5119 pre-configured entry in Configure's %table under key <id> with value
5120 <details> and ``perl Configure <id>'' is called. So, when you want to
5121 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
5122 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
5123 now, which overrides the FreeBSD-elf entry on-the-fly.
5124 [Ralf S. Engelschall]
5126 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
5129 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
5130 on the `perl Configure ...' command line. This way one can compile
5131 OpenSSL libraries with Position Independent Code (PIC) which is needed
5132 for linking it into DSOs.
5133 [Ralf S. Engelschall]
5135 *) Remarkably, export ciphers were totally broken and no-one had noticed!
5139 *) Cleaned up the LICENSE document: The official contact for any license
5140 questions now is the OpenSSL core team under openssl-core@openssl.org.
5141 And add a paragraph about the dual-license situation to make sure people
5142 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
5143 to the OpenSSL toolkit.
5144 [Ralf S. Engelschall]
5146 *) General source tree makefile cleanups: Made `making xxx in yyy...'
5147 display consistent in the source tree and replaced `/bin/rm' by `rm'.
5148 Additonally cleaned up the `make links' target: Remove unnecessary
5149 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
5150 to speed processing and no longer clutter the display with confusing
5151 stuff. Instead only the actually done links are displayed.
5152 [Ralf S. Engelschall]
5154 *) Permit null encryption ciphersuites, used for authentication only. It used
5155 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
5156 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
5160 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
5161 signed attributes when verifying signatures (this would break them),
5162 the detached data encoding was wrong and public keys obtained using
5163 X509_get_pubkey() weren't freed.
5166 *) Add text documentation for the BUFFER functions. Also added a work around
5167 to a Win95 console bug. This was triggered by the password read stuff: the
5168 last character typed gets carried over to the next fread(). If you were
5169 generating a new cert request using 'req' for example then the last
5170 character of the passphrase would be CR which would then enter the first
5174 *) Added the new `Includes OpenSSL Cryptography Software' button as
5175 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
5176 button and can be used by applications based on OpenSSL to show the
5177 relationship to the OpenSSL project.
5178 [Ralf S. Engelschall]
5180 *) Remove confusing variables in function signatures in files
5181 ssl/ssl_lib.c and ssl/ssl.h.
5182 [Lennart Bong <lob@kulthea.stacken.kth.se>]
5184 *) Don't install bss_file.c under PREFIX/include/
5185 [Lennart Bong <lob@kulthea.stacken.kth.se>]
5187 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
5188 functions that return function pointers and has support for NT specific
5189 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
5190 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
5191 unsigned to signed types: this was killing the Win32 compile.
5194 *) Add new certificate file to stack functions,
5195 SSL_add_dir_cert_subjects_to_stack() and
5196 SSL_add_file_cert_subjects_to_stack(). These largely supplant
5197 SSL_load_client_CA_file(), and can be used to add multiple certs easily
5198 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
5199 This means that Apache-SSL and similar packages don't have to mess around
5200 to add as many CAs as they want to the preferred list.
5203 *) Experiment with doxygen documentation. Currently only partially applied to
5205 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
5206 openssl.doxy as the configuration file.
5209 *) Get rid of remaining C++-style comments which strict C compilers hate.
5210 [Ralf S. Engelschall, pointed out by Carlos Amengual]
5212 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
5213 compiled in by default: it has problems with large keys.
5216 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
5217 DH private keys and/or callback functions which directly correspond to
5218 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
5219 is needed for applications which have to configure certificates on a
5220 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
5222 For the RSA certificate situation is makes no difference, but
5223 for the DSA certificate situation this fixes the "no shared cipher"
5224 problem where the OpenSSL cipher selection procedure failed because the
5225 temporary keys were not overtaken from the context and the API provided
5226 no way to reconfigure them.
5227 The new functions now let applications reconfigure the stuff and they
5228 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
5229 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
5230 non-public-API function ssl_cert_instantiate() is used as a helper
5231 function and also to reduce code redundancy inside ssl_rsa.c.
5232 [Ralf S. Engelschall]
5234 *) Move s_server -dcert and -dkey options out of the undocumented feature
5235 area because they are useful for the DSA situation and should be
5236 recognized by the users.
5237 [Ralf S. Engelschall]
5239 *) Fix the cipher decision scheme for export ciphers: the export bits are
5240 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
5241 SSL_EXP_MASK. So, the original variable has to be used instead of the
5242 already masked variable.
5243 [Richard Levitte <levitte@stacken.kth.se>]
5245 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
5246 [Richard Levitte <levitte@stacken.kth.se>]
5248 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
5249 from `int' to `unsigned int' because it's a length and initialized by
5250 EVP_DigestFinal() which expects an `unsigned int *'.
5251 [Richard Levitte <levitte@stacken.kth.se>]
5253 *) Don't hard-code path to Perl interpreter on shebang line of Configure
5254 script. Instead use the usual Shell->Perl transition trick.
5255 [Ralf S. Engelschall]
5257 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
5258 (in addition to RSA certificates) to match the behaviour of `openssl dsa
5259 -noout -modulus' as it's already the case for `openssl rsa -noout
5260 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
5261 currently the public key is printed (a decision which was already done by
5262 `openssl dsa -modulus' in the past) which serves a similar purpose.
5263 Additionally the NO_RSA no longer completely removes the whole -modulus
5264 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
5266 [Ralf S. Engelschall]
5268 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
5269 BIO. See the source (crypto/evp/bio_ok.c) for more info.
5270 [Arne Ansper <arne@ats.cyber.ee>]
5272 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
5273 to be added. Now both 'req' and 'ca' can use new objects defined in the
5277 *) Add cool BIO that does syslog (or event log on NT).
5278 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
5280 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
5281 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
5282 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
5283 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
5286 *) Add preliminary config info for new extension code.
5289 *) Make RSA_NO_PADDING really use no padding.
5290 [Ulf Moeller <ulf@fitug.de>]
5292 *) Generate errors when private/public key check is done.
5295 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
5296 for some CRL extensions and new objects added.
5299 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
5300 key usage extension and fuller support for authority key id.
5303 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
5304 padding method for RSA, which is recommended for new applications in PKCS
5305 #1 v2.0 (RFC 2437, October 1998).
5306 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
5307 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
5308 against Bleichbacher's attack on RSA.
5309 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
5312 *) Updates to the new SSL compression code
5313 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5315 *) Fix so that the version number in the master secret, when passed
5316 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
5317 (because the server will not accept higher), that the version number
5318 is 0x03,0x01, not 0x03,0x00
5319 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5321 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
5322 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
5323 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
5326 *) Support for RAW extensions where an arbitrary extension can be
5327 created by including its DER encoding. See apps/openssl.cnf for
5331 *) Make sure latest Perl versions don't interpret some generated C array
5332 code as Perl array code in the crypto/err/err_genc.pl script.
5333 [Lars Weber <3weber@informatik.uni-hamburg.de>]
5335 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
5336 not many people have the assembler. Various Win32 compilation fixes and
5337 update to the INSTALL.W32 file with (hopefully) more accurate Win32
5341 *) Modify configure script 'Configure' to automatically create crypto/date.h
5342 file under Win32 and also build pem.h from pem.org. New script
5343 util/mkfiles.pl to create the MINFO file on environments that can't do a
5344 'make files': perl util/mkfiles.pl >MINFO should work.
5347 *) Major rework of DES function declarations, in the pursuit of correctness
5348 and purity. As a result, many evil casts evaporated, and some weirdness,
5349 too. You may find this causes warnings in your code. Zapping your evil
5350 casts will probably fix them. Mostly.
5353 *) Fix for a typo in asn1.h. Bug fix to object creation script
5354 obj_dat.pl. It considered a zero in an object definition to mean
5355 "end of object": none of the objects in objects.h have any zeros
5356 so it wasn't spotted.
5357 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
5359 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
5360 Masking (CBCM). In the absence of test vectors, the best I have been able
5361 to do is check that the decrypt undoes the encrypt, so far. Send me test
5362 vectors if you have them.
5365 *) Correct calculation of key length for export ciphers (too much space was
5366 allocated for null ciphers). This has not been tested!
5369 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
5370 message is now correct (it understands "crypto" and "ssl" on its
5371 command line). There is also now an "update" option. This will update
5372 the util/ssleay.num and util/libeay.num files with any new functions.
5374 perl util/mkdef.pl crypto ssl update
5375 it will update them.
5378 *) Overhauled the Perl interface (perl/*):
5379 - ported BN stuff to OpenSSL's different BN library
5380 - made the perl/ source tree CVS-aware
5381 - renamed the package from SSLeay to OpenSSL (the files still contain
5382 their history because I've copied them in the repository)
5383 - removed obsolete files (the test scripts will be replaced
5384 by better Test::Harness variants in the future)
5385 [Ralf S. Engelschall]
5387 *) First cut for a very conservative source tree cleanup:
5388 1. merge various obsolete readme texts into doc/ssleay.txt
5389 where we collect the old documents and readme texts.
5390 2. remove the first part of files where I'm already sure that we no
5391 longer need them because of three reasons: either they are just temporary
5392 files which were left by Eric or they are preserved original files where
5393 I've verified that the diff is also available in the CVS via "cvs diff
5394 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
5395 the crypto/md/ stuff).
5396 [Ralf S. Engelschall]
5398 *) More extension code. Incomplete support for subject and issuer alt
5399 name, issuer and authority key id. Change the i2v function parameters
5400 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
5401 what that's for :-) Fix to ASN1 macro which messed up
5402 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
5405 *) Preliminary support for ENUMERATED type. This is largely copied from the
5409 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
5410 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5412 *) Make sure `make rehash' target really finds the `openssl' program.
5413 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5415 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
5416 like to hear about it if this slows down other processors.
5419 *) Add CygWin32 platform information to Configure script.
5420 [Alan Batie <batie@aahz.jf.intel.com>]
5422 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
5423 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
5425 *) New program nseq to manipulate netscape certificate sequences
5428 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
5432 *) Fixes to BN code. Previously the default was to define BN_RECURSION
5433 but the BN code had some problems that would cause failures when
5434 doing certificate verification and some other functions.
5435 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5437 *) Add ASN1 and PEM code to support netscape certificate sequences.
5440 *) Add ASN1 and PEM code to support netscape certificate sequences.
5443 *) Add several PKIX and private extended key usage OIDs.
5446 *) Modify the 'ca' program to handle the new extension code. Modify
5447 openssl.cnf for new extension format, add comments.
5450 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
5451 and add a sample to openssl.cnf so req -x509 now adds appropriate
5455 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
5456 error code, add initial support to X509_print() and x509 application.
5459 *) Takes a deep breath and start addding X509 V3 extension support code. Add
5460 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
5461 stuff is currently isolated and isn't even compiled yet.
5464 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
5465 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
5466 Removed the versions check from X509 routines when loading extensions:
5467 this allows certain broken certificates that don't set the version
5468 properly to be processed.
5471 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
5472 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
5473 can still be regenerated with "make depend".
5476 *) Spelling mistake in C version of CAST-128.
5477 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
5479 *) Changes to the error generation code. The perl script err-code.pl
5480 now reads in the old error codes and retains the old numbers, only
5481 adding new ones if necessary. It also only changes the .err files if new
5482 codes are added. The makefiles have been modified to only insert errors
5483 when needed (to avoid needlessly modifying header files). This is done
5484 by only inserting errors if the .err file is newer than the auto generated
5485 C file. To rebuild all the error codes from scratch (the old behaviour)
5486 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
5487 or delete all the .err files.
5490 *) CAST-128 was incorrectly implemented for short keys. The C version has
5491 been fixed, but is untested. The assembler versions are also fixed, but
5492 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
5493 to regenerate it if needed.
5494 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
5495 Hagino <itojun@kame.net>]
5497 *) File was opened incorrectly in randfile.c.
5498 [Ulf Möller <ulf@fitug.de>]
5500 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
5501 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
5502 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
5503 al: it's just almost always a UTCTime. Note this patch adds new error
5504 codes so do a "make errors" if there are problems.
5507 *) Correct Linux 1 recognition in config.
5508 [Ulf Möller <ulf@fitug.de>]
5510 *) Remove pointless MD5 hash when using DSA keys in ca.
5511 [Anonymous <nobody@replay.com>]
5513 *) Generate an error if given an empty string as a cert directory. Also
5514 generate an error if handed NULL (previously returned 0 to indicate an
5515 error, but didn't set one).
5516 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
5518 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
5521 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
5522 parameters. This was causing a warning which killed off the Win32 compile.
5525 *) Remove C++ style comments from crypto/bn/bn_local.h.
5526 [Neil Costigan <neil.costigan@celocom.com>]
5528 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
5529 based on a text string, looking up short and long names and finally
5530 "dot" format. The "dot" format stuff didn't work. Added new function
5531 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
5532 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
5533 OID is not part of the table.
5536 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
5537 X509_LOOKUP_by_alias().
5540 *) Sort openssl functions by name.
5543 *) Get the gendsa program working (hopefully) and add it to app list. Remove
5544 encryption from sample DSA keys (in case anyone is interested the password
5548 *) Make _all_ *_free functions accept a NULL pointer.
5549 [Frans Heymans <fheymans@isaserver.be>]
5551 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
5553 [Anonymous <nobody@replay.com>]
5555 *) s_server should send the CAfile as acceptable CAs, not its own cert.
5556 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
5558 *) Don't blow it for numeric -newkey arguments to apps/req.
5559 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
5561 *) Temp key "for export" tests were wrong in s3_srvr.c.
5562 [Anonymous <nobody@replay.com>]
5564 *) Add prototype for temp key callback functions
5565 SSL_CTX_set_tmp_{rsa,dh}_callback().
5568 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
5569 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
5572 *) X509_name_add_entry() freed the wrong thing after an error.
5573 [Arne Ansper <arne@ats.cyber.ee>]
5575 *) rsa_eay.c would attempt to free a NULL context.
5576 [Arne Ansper <arne@ats.cyber.ee>]
5578 *) BIO_s_socket() had a broken should_retry() on Windoze.
5579 [Arne Ansper <arne@ats.cyber.ee>]
5581 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
5582 [Arne Ansper <arne@ats.cyber.ee>]
5584 *) Make sure the already existing X509_STORE->depth variable is initialized
5585 in X509_STORE_new(), but document the fact that this variable is still
5586 unused in the certificate verification process.
5587 [Ralf S. Engelschall]
5589 *) Fix the various library and apps files to free up pkeys obtained from
5590 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
5593 *) Fix reference counting in X509_PUBKEY_get(). This makes
5594 demos/maurice/example2.c work, amongst others, probably.
5595 [Steve Henson and Ben Laurie]
5597 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
5598 `openssl' and second, the shortcut symlinks for the `openssl <command>'
5599 are no longer created. This way we have a single and consistent command
5600 line interface `openssl <command>', similar to `cvs <command>'.
5601 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
5603 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
5604 BIT STRING wrapper always have zero unused bits.
5607 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
5610 *) Make the top-level INSTALL documentation easier to understand.
5613 *) Makefiles updated to exit if an error occurs in a sub-directory
5614 make (including if user presses ^C) [Paul Sutton]
5616 *) Make Montgomery context stuff explicit in RSA data structure.
5619 *) Fix build order of pem and err to allow for generated pem.h.
5622 *) Fix renumbering bug in X509_NAME_delete_entry().
5625 *) Enhanced the err-ins.pl script so it makes the error library number
5626 global and can add a library name. This is needed for external ASN1 and
5627 other error libraries.
5630 *) Fixed sk_insert which never worked properly.
5633 *) Fix ASN1 macros so they can handle indefinite length construted
5634 EXPLICIT tags. Some non standard certificates use these: they can now
5638 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
5639 into a single doc/ssleay.txt bundle. This way the information is still
5640 preserved but no longer messes up this directory. Now it's new room for
5641 the new set of documenation files.
5642 [Ralf S. Engelschall]
5644 *) SETs were incorrectly DER encoded. This was a major pain, because they
5645 shared code with SEQUENCEs, which aren't coded the same. This means that
5646 almost everything to do with SETs or SEQUENCEs has either changed name or
5647 number of arguments.
5648 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
5650 *) Fix test data to work with the above.
5653 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
5654 was already fixed by Eric for 0.9.1 it seems.
5655 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
5657 *) Autodetect FreeBSD3.
5660 *) Fix various bugs in Configure. This affects the following platforms:
5664 unixware-2.0-pentium
5668 *) Eliminate generated files from CVS. Reorder tests to regenerate files
5669 before they are needed.
5672 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
5676 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
5678 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
5679 changed SSLeay to OpenSSL in version strings.
5680 [Ralf S. Engelschall]
5682 *) Some fixups to the top-level documents.
5685 *) Fixed the nasty bug where rsaref.h was not found under compile-time
5686 because the symlink to include/ was missing.
5687 [Ralf S. Engelschall]
5689 *) Incorporated the popular no-RSA/DSA-only patches
5690 which allow to compile a RSA-free SSLeay.
5691 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
5693 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
5694 when "ssleay" is still not found.
5695 [Ralf S. Engelschall]
5697 *) Added more platforms to Configure: Cray T3E, HPUX 11,
5698 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
5700 *) Updated the README file.
5701 [Ralf S. Engelschall]
5703 *) Added various .cvsignore files in the CVS repository subdirs
5704 to make a "cvs update" really silent.
5705 [Ralf S. Engelschall]
5707 *) Recompiled the error-definition header files and added
5708 missing symbols to the Win32 linker tables.
5709 [Ralf S. Engelschall]
5711 *) Cleaned up the top-level documents;
5712 o new files: CHANGES and LICENSE
5713 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
5714 o merged COPYRIGHT into LICENSE
5715 o removed obsolete TODO file
5716 o renamed MICROSOFT to INSTALL.W32
5717 [Ralf S. Engelschall]
5719 *) Removed dummy files from the 0.9.1b source tree:
5720 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
5721 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

5724 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
5725 [Ralf S. Engelschall]
5727 *) Added various platform portability fixes.
5730 *) The Genesis of the OpenSSL rpject:
5731 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
5732 Young and Tim J. Hudson created while they were working for C2Net until
5734 [The OpenSSL Project]
5737 Changes between 0.9.0b and 0.9.1b [not released]
5739 *) Updated a few CA certificates under certs/
5742 *) Changed some BIGNUM api stuff.
5745 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
5746 DGUX x86, Linux Alpha, etc.
5749 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
5750 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
5754 *) Add -strparse option to asn1pars program which parses nested
5756 [Dr Stephen Henson <shenson@bigfoot.com>]
5758 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
5761 *) DSA fix for "ca" program.
5764 *) Added "-genkey" option to "dsaparam" program.
5767 *) Added RIPE MD160 (rmd160) message digest.
5770 *) Added -a (all) option to "ssleay version" command.
5773 *) Added PLATFORM define which is the id given to Configure.
5776 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
5779 *) Extended the ASN.1 parser routines.
5782 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
5785 *) Added a BN_CTX to the BN library.
5788 *) Fixed the weak key values in DES library
5791 *) Changed API in EVP library for cipher aliases.
5794 *) Added support for RC2/64bit cipher.
5797 *) Converted the lhash library to the crypto/mem.c functions.
5800 *) Added more recognized ASN.1 object ids.
5803 *) Added more RSA padding checks for SSL/TLS.
5806 *) Added BIO proxy/filter functionality.
5809 *) Added extra_certs to SSL_CTX which can be used
5810 send extra CA certificates to the client in the CA cert chain sending
5811 process. It can be configured with SSL_CTX_add_extra_chain_cert().
5814 *) Now Fortezza is denied in the authentication phase because
5815 this is key exchange mechanism is not supported by SSLeay at all.
5818 *) Additional PKCS1 checks.
5821 *) Support the string "TLSv1" for all TLS v1 ciphers.
5824 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
5825 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
5828 *) Fixed a few memory leaks.
5831 *) Fixed various code and comment typos.
5834 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
5835 bytes sent in the client random.
