5 Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
7 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
8 NID_pkcs7_encrypted by default: this was wrong since this should almost
9 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
10 the encrypted data type: this is a more sensible place to put it and it
11 allows the PKCS#12 code to be tidied up that duplicated this
15 *) Changed obj_dat.pl script so it takes its input and output files on
16 the command line. This should avoid shell escape redirection problems
20 *) Initial support for certificate extension requests, these are included
21 in things like Xenroll certificate requests. Included functions to allow
22 extensions to be obtained and added.
25 *) -crlf option to s_client and s_server for sending newlines as
26 CRLF (as required by many protocols).
29 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
31 *) Install libRSAglue.a when OpenSSL is built with RSAref.
34 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
35 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
37 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
41 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
42 DH parameters/keys (q is lost during that conversion, but the resulting
43 DH parameters contain its length).
45 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
46 much faster than DH_generate_parameters (which creates parameters
47 where p = 2*q + 1), and also the smaller q makes DH computations
48 much more efficient (160-bit exponentiation instead of 1024-bit
49 exponentiation); so this provides a convenient way to support DHE
50 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
51 utter importance to use
52 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
54 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
55 when such DH parameters are used, because otherwise small subgroup
56 attacks may become possible!
59 *) Avoid memory leak in i2d_DHparams.
62 *) Allow the -k option to be used more than once in the enc program:
63 this allows the same encrypted message to be read by multiple recipients.
66 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
67 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
68 it will always use the numerical form of the OID, even if it has a short
72 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
73 method only got called if p,q,dmp1,dmq1,iqmp components were present,
74 otherwise bn_mod_exp was called. In the case of hardware keys for example
75 no private key components need be present and it might store extra data
76 in the RSA structure, which cannot be accessed from bn_mod_exp. By setting
77 RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for private key
81 *) Added support for SPARC Linux.
84 *) pem_password_cb function type incompatibly changed from
85 typedef int pem_password_cb(char *buf, int size, int rwflag);
87 ....(char *buf, int size, int rwflag, void *userdata);
88 so that applications can pass data to their callbacks:
89 The PEM[_ASN1]_{read,write}... functions and macros now take an
90 additional void * argument, which is just handed through whenever
91 the password callback is called.
92 [Damien Miller <dmiller@ilogic.com.au>, with tiny changes by Bodo Moeller]
94 New function SSL_CTX_set_default_passwd_cb_userdata.
96 Compatibility note: As many C implementations push function arguments
97 onto the stack in reverse order, the new library version is likely to
98 interoperate with programs that have been compiled with the old
99 pem_password_cb definition (PEM_whatever takes some data that
100 happens to be on the stack as its last argument, and the callback
101 just ignores this garbage); but there is no guarantee whatsoever that
104 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
105 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
106 problems not only on Windows, but also on some Unix platforms.
107 To avoid problematic command lines, these definitions are now in an
108 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
109 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
112 *) MIPS III/IV assembler module is reimplemented.
115 *) More DES library cleanups: remove references to srand/rand and
116 delete an unused file.
119 *) Add support for the the free Netwide assembler (NASM) under Win32,
120 since not many people have MASM (ml) and it can be hard to obtain.
121 This is currently experimental but it seems to work OK and pass all
122 the tests. Check out INSTALL.W32 for info.
125 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
126 without temporary keys kept an extra copy of the server key,
127 and connections with temporary keys did not free everything in case
131 *) New function RSA_check_key and new openssl rsa option -check
132 for verifying the consistency of RSA keys.
133 [Ulf Moeller, Bodo Moeller]
135 *) Various changes to make Win32 compile work:
136 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
137 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
138 comparison" warnings.
139 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
142 *) Add a debugging option to PKCS#5 v2 key generation function: when
143 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
144 derived keys are printed to stderr.
147 *) Copy the flags in ASN1_STRING_dup().
148 [Roman E. Pavlov <pre@mo.msk.ru>]
150 *) The x509 application mishandled signing requests containing DSA
151 keys when the signing key was also DSA and the parameters didn't match.
153 It was supposed to omit the parameters when they matched the signing key:
154 the verifying software was then supposed to automatically use the CA's
155 parameters if they were absent from the end user certificate.
157 Omitting parameters is no longer recommended. The test was also
158 the wrong way round! This was probably due to unusual behaviour in
159 EVP_cmp_parameters() which returns 1 if the parameters match.
160 This meant that parameters were omitted when they *didn't* match and
161 the certificate was useless. Certificates signed with 'ca' didn't have
163 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
165 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
166 The interface is as follows:
168 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
169 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
170 "off" is now the default.
171 The library internally uses
172 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
173 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
174 to disable memory-checking temporarily.
176 Some inconsistent states that previously were possible (and were
177 even the default) are now avoided.
179 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
180 with each memory chunk allocated; this is occasionally more helpful
181 than just having a counter.
183 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
185 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
189 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
190 which largely parallels "options", but is for changing API behaviour,
191 whereas "options" are about protocol behaviour.
192 Initial "mode" flags are:
194 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
195 a single record has been written.
196 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
197 retries use the same buffer location.
198 (But all of the contents must be
202 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
205 *) Fix problems with no-hmac etc.
206 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
208 *) New functions RSA_get_default_method(), RSA_set_method() and
209 RSA_get_method(). These allows replacement of RSA_METHODs without having
210 to mess around with the internals of an RSA structure.
213 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
214 Also really enable memory leak checks in openssl.c and in some
216 [Chad C. Mulligan, Bodo Moeller]
218 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
219 up the length of negative integers. This has now been simplified to just
220 store the length when it is first determined and use it later, rather
221 than trying to keep track of where data is copied and updating it to
223 [Steve Henson, reported by Brien Wheeler
224 <bwheeler@authentica-security.com>]
226 *) Add a new function PKCS7_signatureVerify. This allows the verification
227 of a PKCS#7 signature but with the signing certificate passed to the
228 function itself. This contrasts with PKCS7_dataVerify which assumes the
229 certificate is present in the PKCS#7 structure. This isn't always the
230 case: certificates can be omitted from a PKCS#7 structure and be
231 distributed by "out of band" means (such as a certificate database).
234 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
235 function prototypes in pem.h, also change util/mkdef.pl to add the
236 necessary function names.
239 *) mk1mf.pl (used by Windows builds) did not properly read the
240 options set by Configure in the top level Makefile, and Configure
241 was not even able to write more than one option correctly.
242 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
245 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
246 file to be loaded from a BIO or FILE pointer. The BIO version will
247 for example allow memory BIOs to contain config info.
250 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
251 Whoever hopes to achieve shared-library compatibility across versions
252 must use this, not the compile-time macro.
253 (Exercise 0.9.4: Which is the minimum library version required by
255 Note: All this applies only to multi-threaded programs, others don't
259 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
260 through a BIO pair triggered the default case, i.e.
261 SSLerr(...,SSL_R_UNKNOWN_STATE).
264 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
265 can use the SSL library even if none of the specific BIOs is
269 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
270 for the encoded length.
271 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
273 *) Add initial documentation of the X509V3 functions.
276 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
277 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
278 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
279 secure PKCS#8 private key format with a high iteration count.
282 *) Fix determination of Perl interpreter: A perl or perl5
283 _directory_ in $PATH was also accepted as the interpreter.
284 [Ralf S. Engelschall]
286 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
287 wrong with it but it was very old and did things like calling
288 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
292 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
293 to use the new extension code.
296 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
297 with macros. This should make it easier to change their form, add extra
298 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
302 *) Add to configuration table a new entry that can specify an alternative
303 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
304 according to Mark Crispin <MRC@Panda.COM>.
308 *) DES CBC did not update the IV. Weird.
311 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
312 Changing the behaviour of the former might break existing programs --
313 where IV updating is needed, des_ncbc_encrypt can be used.
316 *) When bntest is run from "make test" it drives bc to check its
317 calculations, as well as internally checking them. If an internal check
318 fails, it needs to cause bc to give a non-zero result or make test carries
319 on without noticing the failure. Fixed.
322 *) DES library cleanups.
325 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
326 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
327 ciphers. NOTE: although the key derivation function has been verified
328 against some published test vectors it has not been extensively tested
329 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
333 *) Instead of "mkdir -p", which is not fully portable, use new
334 Perl script "util/mkdir-p.pl".
337 *) Rewrite the way password based encryption (PBE) is handled. It used to
338 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
339 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
340 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
341 the 'parameter' field of the AlgorithmIdentifier is passed to the
342 underlying key generation function so it must do its own ASN1 parsing.
343 This has also changed the EVP_PBE_CipherInit() function which now has a
344 'parameter' argument instead of literal salt and iteration count values
345 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
348 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
349 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
350 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
351 KEY" because this clashed with PKCS#8 unencrypted string. Since this
352 value was just used as a "magic string" and not used directly its
353 value doesn't matter.
356 *) Introduce some semblance of const correctness to BN. Shame C doesn't
360 *) "linux-sparc64" configuration (ultrapenguin).
361 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
362 "linux-sparc" configuration.
363 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
365 *) config now generates no-xxx options for missing ciphers.
368 *) Support the EBCDIC character set (work in progress).
369 File ebcdic.c not yet included because it has a different license.
370 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
372 *) Support BS2000/OSD-POSIX.
373 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
375 *) Make callbacks for key generation use void * instead of char *.
378 *) Make S/MIME samples compile (not yet tested).
381 *) Additional typesafe stacks.
384 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
388 Changes between 0.9.3 and 0.9.3a [29 May 1999]
390 *) New configuration variant "sco5-gcc".
392 *) Updated some demos.
393 [Sean O Riordain, Wade Scholine]
395 *) Add missing BIO_free at exit of pkcs12 application.
398 *) Fix memory leak in conf.c.
401 *) Updates for Win32 to assembler version of MD5.
404 *) Set #! path to perl in apps/der_chop to where we found it
405 instead of using a fixed path.
408 *) SHA library changes for irix64-mips4-cc.
411 *) Improvements for VMS support.
415 Changes between 0.9.2b and 0.9.3 [24 May 1999]
417 *) Bignum library bug fix. IRIX 6 passes "make test" now!
418 This also avoids the problems with SC4.2 and unpatched SC5.
419 [Andy Polyakov <appro@fy.chalmers.se>]
421 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
422 These are required because of the typesafe stack would otherwise break
423 existing code. If old code used a structure member which used to be STACK
424 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
425 sk_num or sk_value it would produce an error because the num, data members
426 are not present in STACK_OF. Now it just produces a warning. sk_set
427 replaces the old method of assigning a value to sk_value
428 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
429 that does this will no longer work (and should use sk_set instead) but
430 this could be regarded as a "questionable" behaviour anyway.
433 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
434 correctly handle encrypted S/MIME data.
437 *) Change type of various DES function arguments from des_cblock
438 (which means, in function argument declarations, pointer to char)
439 to des_cblock * (meaning pointer to array with 8 char elements),
440 which allows the compiler to do more typechecking; it was like
441 that back in SSLeay, but with lots of ugly casts.
443 Introduce new type const_des_cblock.
446 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
447 problems: find RecipientInfo structure that matches recipient certificate
448 and initialise the ASN1 structures properly based on passed cipher.
451 *) Belatedly make the BN tests actually check the results.
454 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
455 to and from BNs: it was completely broken. New compilation option
456 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
457 key elements as negative integers.
460 *) Reorganize and speed up MD5.
461 [Andy Polyakov <appro@fy.chalmers.se>]
464 [Richard Levitte <richard@levitte.org>]
466 *) New option -out to asn1parse to allow the parsed structure to be
467 output to a file. This is most useful when combined with the -strparse
468 option to examine the output of things like OCTET STRINGS.
471 *) Make SSL library a little more fool-proof by not requiring any longer
472 that SSL_set_{accept,connect}_state be called before
473 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
474 in many applications because usually everything *appeared* to work as
475 intended anyway -- now it really works as intended).
478 *) Move openssl.cnf out of lib/.
481 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
482 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
483 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
484 [Ralf S. Engelschall]
486 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
487 handle PKCS#7 enveloped data properly.
488 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
490 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
491 copying pointers. The cert_st handling is changed by this in
492 various ways (and thus what used to be known as ctx->default_cert
493 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
494 any longer when s->cert does not give us what we need).
495 ssl_cert_instantiate becomes obsolete by this change.
496 As soon as we've got the new code right (possibly it already is?),
497 we have solved a couple of bugs of the earlier code where s->cert
498 was used as if it could not have been shared with other SSL structures.
500 Note that using the SSL API in certain dirty ways now will result
501 in different behaviour than observed with earlier library versions:
502 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
503 does not influence s as it used to.
505 In order to clean up things more thoroughly, inside SSL_SESSION
506 we don't use CERT any longer, but a new structure SESS_CERT
507 that holds per-session data (if available); currently, this is
508 the peer's certificate chain and, for clients, the server's certificate
509 and temporary key. CERT holds only those values that can have
510 meaningful defaults in an SSL_CTX.
513 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
514 from the internal representation. Various PKCS#7 fixes: remove some
515 evil casts and set the enc_dig_alg field properly based on the signing
519 *) Allow PKCS#12 password to be set from the command line or the
520 environment. Let 'ca' get its config file name from the environment
521 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
525 *) Allow certificate policies extension to use an IA5STRING for the
526 organization field. This is contrary to the PKIX definition but
527 VeriSign uses it and IE5 only recognises this form. Document 'x509'
531 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
532 without disallowing inline assembler and the like for non-pedantic builds.
535 *) Support Borland C++ builder.
536 [Janez Jere <jj@void.si>, modified by Ulf Möller]
541 *) SHA-1 cleanups and performance enhancements.
542 [Andy Polyakov <appro@fy.chalmers.se>]
544 *) Sparc v8plus assembler for the bignum library.
545 [Andy Polyakov <appro@fy.chalmers.se>]
547 *) Accept any -xxx and +xxx compiler options in Configure.
550 *) Update HPUX configuration.
553 *) Add missing sk_<type>_unshift() function to safestack.h
554 [Ralf S. Engelschall]
556 *) New function SSL_CTX_use_certificate_chain_file that sets the
557 "extra_cert"s in addition to the certificate. (This makes sense
558 only for "PEM" format files, as chains as a whole are not
562 *) Support verify_depth from the SSL API.
563 x509_vfy.c had what can be considered an off-by-one-error:
564 Its depth (which was not part of the external interface)
565 was actually counting the number of certificates in a chain;
566 now it really counts the depth.
569 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
570 instead of X509err, which often resulted in confusing error
571 messages since the error codes are not globally unique
572 (e.g. an alleged error in ssl3_accept when a certificate
573 didn't match the private key).
575 *) New function SSL_CTX_set_session_id_context that allows to set a default
576 value (so that you don't need SSL_set_session_id_context for each
577 connection using the SSL_CTX).
580 *) OAEP decoding bug fix.
583 *) Support INSTALL_PREFIX for package builders, as proposed by
587 *) New Configure options "threads" and "no-threads". For systems
588 where the proper compiler options are known (currently Solaris
589 and Linux), "threads" is the default.
592 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
595 *) Install various scripts to $(OPENSSLDIR)/misc, not to
596 $(INSTALLTOP)/bin -- they shouldn't clutter directories
597 such as /usr/local/bin.
600 *) "make linux-shared" to build shared libraries.
601 [Niels Poppe <niels@netbox.org>]
603 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
606 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
607 extension adding in x509 utility.
610 *) Remove NOPROTO sections and error code comments.
613 *) Partial rewrite of the DEF file generator to now parse the ANSI
617 *) New Configure options --prefix=DIR and --openssldir=DIR.
620 *) Complete rewrite of the error code script(s). It is all now handled
621 by one script at the top level which handles error code gathering,
622 header rewriting and C source file generation. It should be much better
623 than the old method: it now uses a modified version of Ulf's parser to
624 read the ANSI prototypes in all header files (thus the old K&R definitions
625 aren't needed for error creation any more) and do a better job of
626 translating function codes into names. The old 'ASN1 error code imbedded
627 in a comment' is no longer necessary and it doesn't use .err files which
628 have now been deleted. Also the error code call doesn't have to appear all
629 on one line (which resulted in some large lines...).
632 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
635 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
636 0 (which usually indicates a closed connection), but continue reading.
639 *) Fix some race conditions.
642 *) Add support for CRL distribution points extension. Add Certificate
643 Policies and CRL distribution points documentation.
646 *) Move the autogenerated header file parts to crypto/opensslconf.h.
649 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
650 8 of keying material. Merlin has also confirmed interop with this fix
651 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
652 [Merlin Hughes <merlin@baltimore.ie>]
654 *) Fix lots of warnings.
655 [Richard Levitte <levitte@stacken.kth.se>]
657 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
658 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
659 [Richard Levitte <levitte@stacken.kth.se>]
661 *) Fix problems with sizeof(long) == 8.
662 [Andy Polyakov <appro@fy.chalmers.se>]
664 *) Change functions to ANSI C.
667 *) Fix typos in error codes.
668 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
670 *) Remove defunct assembler files from Configure.
673 *) SPARC v8 assembler BIGNUM implementation.
674 [Andy Polyakov <appro@fy.chalmers.se>]
676 *) Support for Certificate Policies extension: both print and set.
677 Various additions to support the r2i method this uses.
680 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
681 return a const string when you are expecting an allocated buffer.
684 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
685 types DirectoryString and DisplayText.
688 *) Add code to allow r2i extensions to access the configuration database,
689 add an LHASH database driver and add several ctx helper functions.
692 *) Fix an evil bug in bn_expand2() which caused various BN functions to
693 fail when they extended the size of a BIGNUM.
696 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
697 support typesafe stack.
700 *) Fix typo in SSL_[gs]et_options().
701 [Nils Frostberg <nils@medcom.se>]
703 *) Delete various functions and files that belonged to the (now obsolete)
704 old X509V3 handling code.
707 *) New Configure option "rsaref".
710 *) Don't auto-generate pem.h.
713 *) Introduce type-safe ASN.1 SETs.
716 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
717 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
719 *) Introduce type-safe STACKs. This will almost certainly break lots of code
720 that links with OpenSSL (well at least cause lots of warnings), but fear
721 not: the conversion is trivial, and it eliminates loads of evil casts. A
722 few STACKed things have been converted already. Feel free to convert more.
723 In the fullness of time, I'll do away with the STACK type altogether.
726 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
727 specified in <certfile> by updating the entry in the index.txt file.
728 This way one no longer has to edit the index.txt file manually for
729 revoking a certificate. The -revoke option does the gory details now.
730 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
732 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
733 `-text' option at all and this way the `-noout -text' combination was
734 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
735 [Ralf S. Engelschall]
737 *) Make sure a corresponding plain text error message exists for the
738 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
739 verify callback function determined that a certificate was revoked.
740 [Ralf S. Engelschall]
742 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
743 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
744 all available cipers including rc5, which was forgotten until now.
745 In order to let the testing shell script know which algorithms
746 are available, a new (up to now undocumented) command
747 "openssl list-cipher-commands" is used.
750 *) Bugfix: s_client occasionally would sleep in select() when
751 it should have checked SSL_pending() first.
754 *) New functions DSA_do_sign and DSA_do_verify to provide access to
755 the raw DSA values prior to ASN.1 encoding.
758 *) Tweaks to Configure
759 [Niels Poppe <niels@netbox.org>]
761 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
765 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
768 *) New config option to avoid instructions that are illegal on the 80386.
769 The default code is faster, but requires at least a 486.
772 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
773 SSL2_SERVER_VERSION (not used at all) macros, which are now the
774 same as SSL2_VERSION anyway.
777 *) New "-showcerts" option for s_client.
780 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
781 application. Various cleanups and fixes.
784 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
785 modify error routines to work internally. Add error codes and PBE init
786 to library startup routines.
789 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
790 packing functions to asn1 and evp. Changed function names and error
794 *) PKCS12 integration: and so it begins... First of several patches to
795 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
799 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
800 and display support for Thawte strong extranet extension.
803 *) Add LinuxPPC support.
804 [Jeff Dubrule <igor@pobox.org>]
806 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
807 bn_div_words in alpha.s.
808 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
810 *) Make sure the RSA OAEP test is skipped under -DRSAref because
811 OAEP isn't supported when OpenSSL is built with RSAref.
812 [Ulf Moeller <ulf@fitug.de>]
814 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
815 so they no longer are missing under -DNOPROTO.
816 [Soren S. Jorvang <soren@t.dk>]
819 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
821 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
822 doesn't work when the session is reused. Coming soon!
825 *) Fix a security hole, that allows sessions to be reused in the wrong
826 context thus bypassing client cert protection! All software that uses
827 client certs and session caches in multiple contexts NEEDS PATCHING to
828 allow session reuse! A fuller solution is in the works.
829 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
831 *) Some more source tree cleanups (removed obsolete files
832 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
833 permission on "config" script to be executable) and a fix for the INSTALL
835 [Ulf Moeller <ulf@fitug.de>]
837 *) Remove some legacy and erroneous uses of malloc, free instead of
839 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
841 *) Make rsa_oaep_test return non-zero on error.
842 [Ulf Moeller <ulf@fitug.de>]
844 *) Add support for native Solaris shared libraries. Configure
845 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
846 if someone would make that last step automatic.
847 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
849 *) ctx_size was not built with the right compiler during "make links". Fixed.
852 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
853 except NULL ciphers". This means the default cipher list will no longer
854 enable NULL ciphers. They need to be specifically enabled e.g. with
855 the string "DEFAULT:eNULL".
858 *) Fix to RSA private encryption routines: if p < q then it would
859 occasionally produce an invalid result. This will only happen with
860 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
863 *) Be less restrictive and allow also `perl util/perlpath.pl
864 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
865 because this way one can also use an interpreter named `perl5' (which is
866 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
867 installed as `perl').
868 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
870 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
871 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
873 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
874 advapi32.lib to Win32 build and change the pem test comparision
875 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
876 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
877 and crypto/des/ede_cbcm_enc.c.
880 *) DES quad checksum was broken on big-endian architectures. Fixed.
883 *) Comment out two functions in bio.h that aren't implemented. Fix up the
884 Win32 test batch file so it (might) work again. The Win32 test batch file
885 is horrible: I feel ill....
888 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
889 in e_os.h. Audit of header files to check ANSI and non ANSI
890 sections: 10 functions were absent from non ANSI section and not exported
891 from Windows DLLs. Fixed up libeay.num for new functions.
894 *) Make `openssl version' output lines consistent.
895 [Ralf S. Engelschall]
897 *) Fix Win32 symbol export lists for BIO functions: Added
898 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
899 to ms/libeay{16,32}.def.
900 [Ralf S. Engelschall]
902 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
903 fine under Unix and passes some trivial tests I've now added. But the
904 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
905 added to make sure no one expects that this stuff really works in the
906 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
907 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
909 [Ralf S. Engelschall]
911 *) Fix the generation of two part addresses in perl.
912 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
914 *) Add config entry for Linux on MIPS.
915 [John Tobey <jtobey@channel1.com>]
917 *) Make links whenever Configure is run, unless we are on Windoze.
920 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
921 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
925 *) Add a useful kludge to allow package maintainers to specify compiler and
926 other platforms details on the command line without having to patch the
927 Configure script everytime: One now can use ``perl Configure
928 <id>:<details>'', i.e. platform ids are allowed to have details appended
929 to them (seperated by colons). This is treated as there would be a static
930 pre-configured entry in Configure's %table under key <id> with value
931 <details> and ``perl Configure <id>'' is called. So, when you want to
932 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
933 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
934 now, which overrides the FreeBSD-elf entry on-the-fly.
935 [Ralf S. Engelschall]
937 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
940 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
941 on the `perl Configure ...' command line. This way one can compile
942 OpenSSL libraries with Position Independent Code (PIC) which is needed
943 for linking it into DSOs.
944 [Ralf S. Engelschall]
946 *) Remarkably, export ciphers were totally broken and no-one had noticed!
950 *) Cleaned up the LICENSE document: The official contact for any license
951 questions now is the OpenSSL core team under openssl-core@openssl.org.
952 And add a paragraph about the dual-license situation to make sure people
953 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
954 to the OpenSSL toolkit.
955 [Ralf S. Engelschall]
957 *) General source tree makefile cleanups: Made `making xxx in yyy...'
958 display consistent in the source tree and replaced `/bin/rm' by `rm'.
959 Additonally cleaned up the `make links' target: Remove unnecessary
960 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
961 to speed processing and no longer clutter the display with confusing
962 stuff. Instead only the actually done links are displayed.
963 [Ralf S. Engelschall]
965 *) Permit null encryption ciphersuites, used for authentication only. It used
966 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
967 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
971 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
972 signed attributes when verifying signatures (this would break them),
973 the detached data encoding was wrong and public keys obtained using
974 X509_get_pubkey() weren't freed.
977 *) Add text documentation for the BUFFER functions. Also added a work around
978 to a Win95 console bug. This was triggered by the password read stuff: the
979 last character typed gets carried over to the next fread(). If you were
980 generating a new cert request using 'req' for example then the last
981 character of the passphrase would be CR which would then enter the first
985 *) Added the new `Includes OpenSSL Cryptography Software' button as
986 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
987 button and can be used by applications based on OpenSSL to show the
988 relationship to the OpenSSL project.
989 [Ralf S. Engelschall]
991 *) Remove confusing variables in function signatures in files
992 ssl/ssl_lib.c and ssl/ssl.h.
993 [Lennart Bong <lob@kulthea.stacken.kth.se>]
995 *) Don't install bss_file.c under PREFIX/include/
996 [Lennart Bong <lob@kulthea.stacken.kth.se>]
998 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
999 functions that return function pointers and has support for NT specific
1000 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
1001 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
1002 unsigned to signed types: this was killing the Win32 compile.
1005 *) Add new certificate file to stack functions,
1006 SSL_add_dir_cert_subjects_to_stack() and
1007 SSL_add_file_cert_subjects_to_stack(). These largely supplant
1008 SSL_load_client_CA_file(), and can be used to add multiple certs easily
1009 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
1010 This means that Apache-SSL and similar packages don't have to mess around
1011 to add as many CAs as they want to the preferred list.
1014 *) Experiment with doxygen documentation. Currently only partially applied to
1016 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
1017 openssl.doxy as the configuration file.
1020 *) Get rid of remaining C++-style comments which strict C compilers hate.
1021 [Ralf S. Engelschall, pointed out by Carlos Amengual]
1023 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
1024 compiled in by default: it has problems with large keys.
1027 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
1028 DH private keys and/or callback functions which directly correspond to
1029 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
1030 is needed for applications which have to configure certificates on a
1031 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
1033 For the RSA certificate situation is makes no difference, but
1034 for the DSA certificate situation this fixes the "no shared cipher"
1035 problem where the OpenSSL cipher selection procedure failed because the
1036 temporary keys were not overtaken from the context and the API provided
1037 no way to reconfigure them.
1038 The new functions now let applications reconfigure the stuff and they
1039 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
1040 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
1041 non-public-API function ssl_cert_instantiate() is used as a helper
1042 function and also to reduce code redundancy inside ssl_rsa.c.
1043 [Ralf S. Engelschall]
1045 *) Move s_server -dcert and -dkey options out of the undocumented feature
1046 area because they are useful for the DSA situation and should be
1047 recognized by the users.
1048 [Ralf S. Engelschall]
1050 *) Fix the cipher decision scheme for export ciphers: the export bits are
1051 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
1052 SSL_EXP_MASK. So, the original variable has to be used instead of the
1053 already masked variable.
1054 [Richard Levitte <levitte@stacken.kth.se>]
1056 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
1057 [Richard Levitte <levitte@stacken.kth.se>]
1059 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
1060 from `int' to `unsigned int' because it's a length and initialized by
1061 EVP_DigestFinal() which expects an `unsigned int *'.
1062 [Richard Levitte <levitte@stacken.kth.se>]
1064 *) Don't hard-code path to Perl interpreter on shebang line of Configure
1065 script. Instead use the usual Shell->Perl transition trick.
1066 [Ralf S. Engelschall]
1068 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
1069 (in addition to RSA certificates) to match the behaviour of `openssl dsa
1070 -noout -modulus' as it's already the case for `openssl rsa -noout
1071 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
1072 currently the public key is printed (a decision which was already done by
1073 `openssl dsa -modulus' in the past) which serves a similar purpose.
1074 Additionally the NO_RSA no longer completely removes the whole -modulus
1075 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
1077 [Ralf S. Engelschall]
1079 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
1080 BIO. See the source (crypto/evp/bio_ok.c) for more info.
1081 [Arne Ansper <arne@ats.cyber.ee>]
1083 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
1084 to be added. Now both 'req' and 'ca' can use new objects defined in the
1088 *) Add cool BIO that does syslog (or event log on NT).
1089 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
1091 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
1092 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
1093 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
1094 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
1097 *) Add preliminary config info for new extension code.
1100 *) Make RSA_NO_PADDING really use no padding.
1101 [Ulf Moeller <ulf@fitug.de>]
1103 *) Generate errors when private/public key check is done.
1106 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
1107 for some CRL extensions and new objects added.
1110 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
1111 key usage extension and fuller support for authority key id.
1114 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
1115 padding method for RSA, which is recommended for new applications in PKCS
1116 #1 v2.0 (RFC 2437, October 1998).
1117 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
1118 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
1119 against Bleichbacher's attack on RSA.
1120 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
1123 *) Updates to the new SSL compression code
1124 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1126 *) Fix so that the version number in the master secret, when passed
1127 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
1128 (because the server will not accept higher), that the version number
1129 is 0x03,0x01, not 0x03,0x00
1130 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1132 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
1133 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
1134 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
1137 *) Support for RAW extensions where an arbitrary extension can be
1138 created by including its DER encoding. See apps/openssl.cnf for
1142 *) Make sure latest Perl versions don't interpret some generated C array
1143 code as Perl array code in the crypto/err/err_genc.pl script.
1144 [Lars Weber <3weber@informatik.uni-hamburg.de>]
1146 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
1147 not many people have the assembler. Various Win32 compilation fixes and
1148 update to the INSTALL.W32 file with (hopefully) more accurate Win32
1152 *) Modify configure script 'Configure' to automatically create crypto/date.h
1153 file under Win32 and also build pem.h from pem.org. New script
1154 util/mkfiles.pl to create the MINFO file on environments that can't do a
1155 'make files': perl util/mkfiles.pl >MINFO should work.
1158 *) Major rework of DES function declarations, in the pursuit of correctness
1159 and purity. As a result, many evil casts evaporated, and some weirdness,
1160 too. You may find this causes warnings in your code. Zapping your evil
1161 casts will probably fix them. Mostly.
1164 *) Fix for a typo in asn1.h. Bug fix to object creation script
1165 obj_dat.pl. It considered a zero in an object definition to mean
1166 "end of object": none of the objects in objects.h have any zeros
1167 so it wasn't spotted.
1168 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
1170 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
1171 Masking (CBCM). In the absence of test vectors, the best I have been able
1172 to do is check that the decrypt undoes the encrypt, so far. Send me test
1173 vectors if you have them.
1176 *) Correct calculation of key length for export ciphers (too much space was
1177 allocated for null ciphers). This has not been tested!
1180 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
1181 message is now correct (it understands "crypto" and "ssl" on its
1182 command line). There is also now an "update" option. This will update
1183 the util/ssleay.num and util/libeay.num files with any new functions.
1185 perl util/mkdef.pl crypto ssl update
1186 it will update them.
1189 *) Overhauled the Perl interface (perl/*):
1190 - ported BN stuff to OpenSSL's different BN library
1191 - made the perl/ source tree CVS-aware
1192 - renamed the package from SSLeay to OpenSSL (the files still contain
1193 their history because I've copied them in the repository)
1194 - removed obsolete files (the test scripts will be replaced
1195 by better Test::Harness variants in the future)
1196 [Ralf S. Engelschall]
1198 *) First cut for a very conservative source tree cleanup:
1199 1. merge various obsolete readme texts into doc/ssleay.txt
1200 where we collect the old documents and readme texts.
1201 2. remove the first part of files where I'm already sure that we no
1202 longer need them because of three reasons: either they are just temporary
1203 files which were left by Eric or they are preserved original files where
1204 I've verified that the diff is also available in the CVS via "cvs diff
1205 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
1206 the crypto/md/ stuff).
1207 [Ralf S. Engelschall]
1209 *) More extension code. Incomplete support for subject and issuer alt
1210 name, issuer and authority key id. Change the i2v function parameters
1211 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
1212 what that's for :-) Fix to ASN1 macro which messed up
1213 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
1216 *) Preliminary support for ENUMERATED type. This is largely copied from the
1220 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
1221 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1223 *) Make sure `make rehash' target really finds the `openssl' program.
1224 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1226 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
1227 like to hear about it if this slows down other processors.
1230 *) Add CygWin32 platform information to Configure script.
1231 [Alan Batie <batie@aahz.jf.intel.com>]
1233 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
1234 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
1236 *) New program nseq to manipulate netscape certificate sequences
1239 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
1243 *) Fixes to BN code. Previously the default was to define BN_RECURSION
1244 but the BN code had some problems that would cause failures when
1245 doing certificate verification and some other functions.
1246 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1248 *) Add ASN1 and PEM code to support netscape certificate sequences.
1251 *) Add ASN1 and PEM code to support netscape certificate sequences.
1254 *) Add several PKIX and private extended key usage OIDs.
1257 *) Modify the 'ca' program to handle the new extension code. Modify
1258 openssl.cnf for new extension format, add comments.
1261 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
1262 and add a sample to openssl.cnf so req -x509 now adds appropriate
1266 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
1267 error code, add initial support to X509_print() and x509 application.
1270 *) Takes a deep breath and start addding X509 V3 extension support code. Add
1271 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
1272 stuff is currently isolated and isn't even compiled yet.
1275 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
1276 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
1277 Removed the versions check from X509 routines when loading extensions:
1278 this allows certain broken certificates that don't set the version
1279 properly to be processed.
1282 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
1283 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
1284 can still be regenerated with "make depend".
1287 *) Spelling mistake in C version of CAST-128.
1288 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
1290 *) Changes to the error generation code. The perl script err-code.pl
1291 now reads in the old error codes and retains the old numbers, only
1292 adding new ones if necessary. It also only changes the .err files if new
1293 codes are added. The makefiles have been modified to only insert errors
1294 when needed (to avoid needlessly modifying header files). This is done
1295 by only inserting errors if the .err file is newer than the auto generated
1296 C file. To rebuild all the error codes from scratch (the old behaviour)
1297 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
1298 or delete all the .err files.
1301 *) CAST-128 was incorrectly implemented for short keys. The C version has
1302 been fixed, but is untested. The assembler versions are also fixed, but
1303 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
1304 to regenerate it if needed.
1305 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
1306 Hagino <itojun@kame.net>]
1308 *) File was opened incorrectly in randfile.c.
1309 [Ulf Möller <ulf@fitug.de>]
1311 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
1312 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
1313 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
1314 al: it's just almost always a UTCTime. Note this patch adds new error
1315 codes so do a "make errors" if there are problems.
1318 *) Correct Linux 1 recognition in config.
1319 [Ulf Möller <ulf@fitug.de>]
1321 *) Remove pointless MD5 hash when using DSA keys in ca.
1322 [Anonymous <nobody@replay.com>]
1324 *) Generate an error if given an empty string as a cert directory. Also
1325 generate an error if handed NULL (previously returned 0 to indicate an
1326 error, but didn't set one).
1327 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
1329 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
1332 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
1333 parameters. This was causing a warning which killed off the Win32 compile.
1336 *) Remove C++ style comments from crypto/bn/bn_local.h.
1337 [Neil Costigan <neil.costigan@celocom.com>]
1339 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
1340 based on a text string, looking up short and long names and finally
1341 "dot" format. The "dot" format stuff didn't work. Added new function
1342 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
1343 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
1344 OID is not part of the table.
1347 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1348 X509_LOOKUP_by_alias().
1351 *) Sort openssl functions by name.
1354 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1355 encryption from sample DSA keys (in case anyone is interested the password
1359 *) Make _all_ *_free functions accept a NULL pointer.
1360 [Frans Heymans <fheymans@isaserver.be>]
1362 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1364 [Anonymous <nobody@replay.com>]
1366 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1367 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1369 *) Don't blow it for numeric -newkey arguments to apps/req.
1370 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1372 *) Temp key "for export" tests were wrong in s3_srvr.c.
1373 [Anonymous <nobody@replay.com>]
1375 *) Add prototype for temp key callback functions
1376 SSL_CTX_set_tmp_{rsa,dh}_callback().
1379 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1380 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1383 *) X509_name_add_entry() freed the wrong thing after an error.
1384 [Arne Ansper <arne@ats.cyber.ee>]
1386 *) rsa_eay.c would attempt to free a NULL context.
1387 [Arne Ansper <arne@ats.cyber.ee>]
1389 *) BIO_s_socket() had a broken should_retry() on Windoze.
1390 [Arne Ansper <arne@ats.cyber.ee>]
1392 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1393 [Arne Ansper <arne@ats.cyber.ee>]
1395 *) Make sure the already existing X509_STORE->depth variable is initialized
1396 in X509_STORE_new(), but document the fact that this variable is still
1397 unused in the certificate verification process.
1398 [Ralf S. Engelschall]
1400 *) Fix the various library and apps files to free up pkeys obtained from
1401 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1404 *) Fix reference counting in X509_PUBKEY_get(). This makes
1405 demos/maurice/example2.c work, amongst others, probably.
1406 [Steve Henson and Ben Laurie]
1408 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1409 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1410 are no longer created. This way we have a single and consistent command
1411 line interface `openssl <command>', similar to `cvs <command>'.
1412 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1414 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1415 BIT STRING wrapper always have zero unused bits.
1418 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1421 *) Make the top-level INSTALL documentation easier to understand.
1424 *) Makefiles updated to exit if an error occurs in a sub-directory
1425 make (including if user presses ^C) [Paul Sutton]
1427 *) Make Montgomery context stuff explicit in RSA data structure.
1430 *) Fix build order of pem and err to allow for generated pem.h.
1433 *) Fix renumbering bug in X509_NAME_delete_entry().
1436 *) Enhanced the err-ins.pl script so it makes the error library number
1437 global and can add a library name. This is needed for external ASN1 and
1438 other error libraries.
1441 *) Fixed sk_insert which never worked properly.
1444 *) Fix ASN1 macros so they can handle indefinite length construted
1445 EXPLICIT tags. Some non standard certificates use these: they can now
1449 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1450 into a single doc/ssleay.txt bundle. This way the information is still
1451 preserved but no longer messes up this directory. Now it's new room for
1452 the new set of documenation files.
1453 [Ralf S. Engelschall]
1455 *) SETs were incorrectly DER encoded. This was a major pain, because they
1456 shared code with SEQUENCEs, which aren't coded the same. This means that
1457 almost everything to do with SETs or SEQUENCEs has either changed name or
1458 number of arguments.
1459 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1461 *) Fix test data to work with the above.
1464 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1465 was already fixed by Eric for 0.9.1 it seems.
1466 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1468 *) Autodetect FreeBSD3.
1471 *) Fix various bugs in Configure. This affects the following platforms:
1475 unixware-2.0-pentium
1479 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1480 before they are needed.
1483 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1487 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1489 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1490 changed SSLeay to OpenSSL in version strings.
1491 [Ralf S. Engelschall]
1493 *) Some fixups to the top-level documents.
1496 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1497 because the symlink to include/ was missing.
1498 [Ralf S. Engelschall]
1500 *) Incorporated the popular no-RSA/DSA-only patches
1501 which allow to compile a RSA-free SSLeay.
1502 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1504 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1505 when "ssleay" is still not found.
1506 [Ralf S. Engelschall]
1508 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1509 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1511 *) Updated the README file.
1512 [Ralf S. Engelschall]
1514 *) Added various .cvsignore files in the CVS repository subdirs
1515 to make a "cvs update" really silent.
1516 [Ralf S. Engelschall]
1518 *) Recompiled the error-definition header files and added
1519 missing symbols to the Win32 linker tables.
1520 [Ralf S. Engelschall]
1522 *) Cleaned up the top-level documents;
1523 o new files: CHANGES and LICENSE
1524 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1525 o merged COPYRIGHT into LICENSE
1526 o removed obsolete TODO file
1527 o renamed MICROSOFT to INSTALL.W32
1528 [Ralf S. Engelschall]
1530 *) Removed dummy files from the 0.9.1b source tree:
1531 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1532 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
1533 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
1534 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
1535 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1536 [Ralf S. Engelschall]
1538 *) Added various platform portability fixes.
1541 *) The Genesis of the OpenSSL rpject:
1542 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1543 Young and Tim J. Hudson created while they were working for C2Net until
1545 [The OpenSSL Project]
1548 Changes between 0.9.0b and 0.9.1b [not released]
1550 *) Updated a few CA certificates under certs/
1553 *) Changed some BIGNUM api stuff.
1556 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1557 DGUX x86, Linux Alpha, etc.
1560 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1561 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1565 *) Add -strparse option to asn1pars program which parses nested
1567 [Dr Stephen Henson <shenson@bigfoot.com>]
1569 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1572 *) DSA fix for "ca" program.
1575 *) Added "-genkey" option to "dsaparam" program.
1578 *) Added RIPE MD160 (rmd160) message digest.
1581 *) Added -a (all) option to "ssleay version" command.
1584 *) Added PLATFORM define which is the id given to Configure.
1587 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1590 *) Extended the ASN.1 parser routines.
1593 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1596 *) Added a BN_CTX to the BN library.
1599 *) Fixed the weak key values in DES library
1602 *) Changed API in EVP library for cipher aliases.
1605 *) Added support for RC2/64bit cipher.
1608 *) Converted the lhash library to the crypto/mem.c functions.
1611 *) Added more recognized ASN.1 object ids.
1614 *) Added more RSA padding checks for SSL/TLS.
1617 *) Added BIO proxy/filter functionality.
1620 *) Added extra_certs to SSL_CTX which can be used
1621 send extra CA certificates to the client in the CA cert chain sending
1622 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1625 *) Now Fortezza is denied in the authentication phase because
1626 this is key exchange mechanism is not supported by SSLeay at all.
1629 *) Additional PKCS1 checks.
1632 *) Support the string "TLSv1" for all TLS v1 ciphers.
1635 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1636 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1639 *) Fixed a few memory leaks.
1642 *) Fixed various code and comment typos.
1645 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1646 bytes sent in the client random.
