6 Changes between 0.9.1c and 0.9.2
8 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
9 message is now correct (it understands "crypto" and "ssl" on its
10 command line). There is also now an "update" option. This will update
11 the util/ssleay.num and util/libeay.num files with any new functions.
13 perl util/mkdef.pl crypto ssl update
16 *) Overhauled the Perl interface (perl/*):
17 - ported BN stuff to OpenSSL's different BN library
18 - made the perl/ source tree CVS-aware
19 - renamed the package from SSLeay to OpenSSL (the files still contain
20 their history because I've copied them in the repository)
21 - removed obsolete files (the test scripts will be replaced
22 by better Test::Harness variants in the future)
25 *) First cut for a very conservative source tree cleanup:
26 1. merge various obsolete readme texts into doc/ssleay.txt
27 where we collect the old documents and readme texts.
28 2. remove the first part of files where I'm already sure that we no
29 longer need them because of three reasons: either they are just temporary
30 files which were left by Eric or they are preserved original files where
31 I've verified that the diff is also available in the CVS via "cvs diff
32 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
33 the crypto/md/ stuff).
36 *) More extension code. Incomplete support for subject and issuer alt
37 name, issuer and authority key id. Change the i2v function parameters
38 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
39 what that's for :-) Fix to ASN1 macro which messed up
40 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
43 *) Preliminary support for ENUMERATED type. This is largely copied from the
47 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
48 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
50 *) Make sure `make rehash' target really finds the `openssl' program.
51 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
53 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
54 like to hear about it if this slows down other processors.
57 *) Add CygWin32 platform information to Configure script.
58 [Alan Batie <batie@aahz.jf.intel.com>]
60 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
61 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
63 *) New program nseq to manipulate netscape certificate sequences
66 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
70 *) Fixes to BN code. Previously the default was to define BN_RECURSION
71 but the BN code had some problems that would cause failures when
72 doing certificate verification and some other functions.
73 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
75 *) Add ASN1 and PEM code to support netscape certificate sequences.
78 *) Add ASN1 and PEM code to support netscape certificate sequences.
81 *) Add several PKIX and private extended key usage OIDs.
84 *) Modify the 'ca' program to handle the new extension code. Modify
85 openssl.cnf for new extension format, add comments.
88 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
89 and add a sample to openssl.cnf so req -x509 now adds appropriate
93 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
94 error code, add initial support to X509_print() and x509 application.
97 *) Takes a deep breath and start addding X509 V3 extension support code. Add
98 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
99 stuff is currently isolated and isn't even compiled yet.
102 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
103 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
104 Removed the versions check from X509 routines when loading extensions:
105 this allows certain broken certificates that don't set the version
106 properly to be processed.
109 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
110 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
111 can still be regenerated with "make depend".
114 *) Spelling mistake in C version of CAST-128.
115 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
117 *) Changes to the error generation code. The perl script err-code.pl
118 now reads in the old error codes and retains the old numbers, only
119 adding new ones if necessary. It also only changes the .err files if new
120 codes are added. The makefiles have been modified to only insert errors
121 when needed (to avoid needlessly modifying header files). This is done
122 by only inserting errors if the .err file is newer than the auto generated
123 C file. To rebuild all the error codes from scratch (the old behaviour)
124 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
125 or delete all the .err files.
128 *) CAST-128 was incorrectly implemented for short keys. The C version has
129 been fixed, but is untested. The assembler versions are also fixed, but
130 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
131 to regenerate it if needed.
132 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
133 Hagino <itojun@kame.net>]
135 *) File was opened incorrectly in randfile.c.
136 [Ulf Möller <ulf@fitug.de>]
138 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
139 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
140 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
141 al: it's just almost always a UTCTime. Note this patch adds new error
142 codes so do a "make errors" if there are problems.
145 *) Correct Linux 1 recognition in config.
146 [Ulf Möller <ulf@fitug.de>]
148 *) Remove pointless MD5 hash when using DSA keys in ca.
149 [Anonymous <nobody@replay.com>]
151 *) Generate an error if given an empty string as a cert directory. Also
152 generate an error if handed NULL (previously returned 0 to indicate an
153 error, but didn't set one).
154 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
156 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
159 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
160 parameters. This was causing a warning which killed off the Win32 compile.
163 *) Remove C++ style comments from crypto/bn/bn_local.h.
164 [Neil Costigan <neil.costigan@celocom.com>]
166 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
167 based on a text string, looking up short and long names and finally
168 "dot" format. The "dot" format stuff didn't work. Added new function
169 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
170 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
171 OID is not part of the table.
174 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
175 X509_LOOKUP_by_alias().
178 *) Sort openssl functions by name.
181 *) Get the gendsa program working (hopefully) and add it to app list. Remove
182 encryption from sample DSA keys (in case anyone is interested the password
186 *) Make _all_ *_free functions accept a NULL pointer.
187 [Frans Heymans <fheymans@isaserver.be>]
189 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
191 [Anonymous <nobody@replay.com>]
193 *) s_server should send the CAfile as acceptable CAs, not its own cert.
194 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
196 *) Don't blow it for numeric -newkey arguments to apps/req.
197 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
199 *) Temp key "for export" tests were wrong in s3_srvr.c.
200 [Anonymous <nobody@replay.com>]
202 *) Add prototype for temp key callback functions
203 SSL_CTX_set_tmp_{rsa,dh}_callback().
206 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
207 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
210 *) X509_name_add_entry() freed the wrong thing after an error.
211 [Arne Ansper <arne@ats.cyber.ee>]
213 *) rsa_eay.c would attempt to free a NULL context.
214 [Arne Ansper <arne@ats.cyber.ee>]
216 *) BIO_s_socket() had a broken should_retry() on Windoze.
217 [Arne Ansper <arne@ats.cyber.ee>]
219 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
220 [Arne Ansper <arne@ats.cyber.ee>]
222 *) Make sure the already existing X509_STORE->depth variable is initialized
223 in X509_STORE_new(), but document the fact that this variable is still
224 unused in the certificate verification process.
225 [Ralf S. Engelschall]
227 *) Fix the various library and apps files to free up pkeys obtained from
228 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
231 *) Fix reference counting in X509_PUBKEY_get(). This makes
232 demos/maurice/example2.c work, amongst others, probably.
233 [Steve Henson and Ben Laurie]
235 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
236 `openssl' and second, the shortcut symlinks for the `openssl <command>'
237 are no longer created. This way we have a single and consistent command
238 line interface `openssl <command>', similar to `cvs <command>'.
239 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
241 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
242 BIT STRING wrapper always have zero unused bits.
245 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
248 *) Make the top-level INSTALL documentation easier to understand.
251 *) Makefiles updated to exit if an error occurs in a sub-directory
252 make (including if user presses ^C) [Paul Sutton]
254 *) Make Montgomery context stuff explicit in RSA data structure.
257 *) Fix build order of pem and err to allow for generated pem.h.
260 *) Fix renumbering bug in X509_NAME_delete_entry().
263 *) Enhanced the err-ins.pl script so it makes the error library number
264 global and can add a library name. This is needed for external ASN1 and
265 other error libraries.
268 *) Fixed sk_insert which never worked properly.
271 *) Fix ASN1 macros so they can handle indefinite length construted
272 EXPLICIT tags. Some non standard certificates use these: they can now
276 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
277 into a single doc/ssleay.txt bundle. This way the information is still
278 preserved but no longer messes up this directory. Now it's new room for
279 the new set of documenation files.
280 [Ralf S. Engelschall]
282 *) SETs were incorrectly DER encoded. This was a major pain, because they
283 shared code with SEQUENCEs, which aren't coded the same. This means that
284 almost everything to do with SETs or SEQUENCEs has either changed name or
286 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
288 *) Fix test data to work with the above.
291 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
292 was already fixed by Eric for 0.9.1 it seems.
293 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
295 *) Autodetect FreeBSD3.
298 *) Fix various bugs in Configure. This affects the following platforms:
306 *) Eliminate generated files from CVS. Reorder tests to regenerate files
307 before they are needed.
310 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
313 Changes between 0.9.1b and 0.9.1c
315 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
316 changed SSLeay to OpenSSL in version strings.
317 [Ralf S. Engelschall]
319 *) Some fixups to the top-level documents.
322 *) Fixed the nasty bug where rsaref.h was not found under compile-time
323 because the symlink to include/ was missing.
324 [Ralf S. Engelschall]
326 *) Incorporated the popular no-RSA/DSA-only patches
327 which allow to compile a RSA-free SSLeay.
328 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
330 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
331 when "ssleay" is still not found.
332 [Ralf S. Engelschall]
334 *) Added more platforms to Configure: Cray T3E, HPUX 11,
335 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
337 *) Updated the README file.
338 [Ralf S. Engelschall]
340 *) Added various .cvsignore files in the CVS repository subdirs
341 to make a "cvs update" really silent.
342 [Ralf S. Engelschall]
344 *) Recompiled the error-definition header files and added
345 missing symbols to the Win32 linker tables.
346 [Ralf S. Engelschall]
348 *) Cleaned up the top-level documents;
349 o new files: CHANGES and LICENSE
350 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
351 o merged COPYRIGHT into LICENSE
352 o removed obsolete TODO file
353 o renamed MICROSOFT to INSTALL.W32
354 [Ralf S. Engelschall]
356 *) Removed dummy files from the 0.9.1b source tree:
357 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
358 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
359 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
360 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
361 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
362 [Ralf S. Engelschall]
364 *) Added various platform portability fixes.
367 *) The Genesis of the OpenSSL rpject:
368 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
369 Young and Tim J. Hudson created while they were working for C2Net until
371 [The OpenSSL Project]
373 Changes between 0.9.0b and 0.9.1b
375 *) Updated a few CA certificates under certs/
378 *) Changed some BIGNUM api stuff.
381 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
382 DGUX x86, Linux Alpha, etc.
385 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
386 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
390 *) Add -strparse option to asn1pars program which parses nested
392 [Dr Stephen Henson <shenson@bigfoot.com>]
394 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
397 *) DSA fix for "ca" program.
400 *) Added "-genkey" option to "dsaparam" program.
403 *) Added RIPE MD160 (rmd160) message digest.
406 *) Added -a (all) option to "ssleay version" command.
409 *) Added PLATFORM define which is the id given to Configure.
412 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
415 *) Extended the ASN.1 parser routines.
418 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
421 *) Added a BN_CTX to the BN library.
424 *) Fixed the weak key values in DES library
427 *) Changed API in EVP library for cipher aliases.
430 *) Added support for RC2/64bit cipher.
433 *) Converted the lhash library to the crypto/mem.c functions.
436 *) Added more recognized ASN.1 object ids.
439 *) Added more RSA padding checks for SSL/TLS.
442 *) Added BIO proxy/filter functionality.
445 *) Added extra_certs to SSL_CTX which can be used
446 send extra CA certificates to the client in the CA cert chain sending
447 process. It can be configured with SSL_CTX_add_extra_chain_cert().
450 *) Now Fortezza is denied in the authentication phase because
451 this is key exchange mechanism is not supported by SSLeay at all.
454 *) Additional PKCS1 checks.
457 *) Support the string "TLSv1" for all TLS v1 ciphers.
460 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
461 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
464 *) Fixed a few memory leaks.
467 *) Fixed various code and comment typos.
470 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
471 bytes sent in the client random.
