6 Changes between 0.9.2b and 0.9.3 [XX May 1999]
7 [I suggest using the same format for the
8 date as in opensslv.h. 0.9.1c used
9 hyphens in the date, so I wrote
10 [23-Dec-1998] down below; but in later
11 versions, these hyphens are gone.]
13 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
14 problems: find RecipientInfo structure that matches recipient certificate
15 and initialise the ASN1 structures properly based on passed cipher.
18 *) Belatedly make the BN tests actually check the results.
21 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
22 to and from BNs: it was completely broken. New compilation option
23 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
24 key elements as negative integers.
27 *) Reorganize and speed up MD5.
28 [Andy Polyakov <appro@fy.chalmers.se>]
31 [Richard Levitte <richard@levitte.org>]
33 *) New option -out to asn1parse to allow the parsed structure to be
34 output to a file. This is most useful when combined with the -strparse
35 option to examine the output of things like OCTET STRINGS.
38 *) Make SSL library a little more fool-proof by not requiring any longer
39 that SSL_set_{accept,connect}_state be called before
40 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
41 in many applications because usually everything *appeared* to work as
42 intended anyway -- now it really works as intended).
45 *) Move openssl.cnf out of lib/.
48 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
49 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
50 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
53 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
54 handle PKCS#7 enveloped data properly.
55 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
57 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
58 copying pointers. The cert_st handling is changed by this in
59 various ways (and thus what used to be known as ctx->default_cert
60 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
61 any longer when s->cert does not give us what we need).
62 ssl_cert_instantiate becomes obsolete by this change.
63 As soon as we've got the new code right (possibly it already is?),
64 we have solved a couple of bugs of the earlier code where s->cert
65 was used as if it could not have been shared with other SSL structures.
67 Note that using the SSL API in certain dirty ways now will result
68 in different behaviour than observed with earlier library versions:
69 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
70 does not influence s as it used to.
72 In order to clean up things more thoroughly, inside SSL_SESSION
73 we don't use CERT any longer, but a new structure SESS_CERT
74 that holds per-session data (if available); currently, this is
75 the peer's certificate chain and, for clients, the server's certificate
76 and temporary key. CERT holds only those values that can have
77 meaningful defaults in an SSL_CTX.
80 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
81 from the internal representation. Various PKCS#7 fixes: remove some
82 evil casts and set the enc_dig_alg field properly based on the signing
86 *) Allow PKCS#12 password to be set from the command line or the
87 environment. Let 'ca' get its config file name from the environment
88 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
92 *) Allow certificate policies extension to use an IA5STRING for the
93 organization field. This is contrary to the PKIX definition but
94 VeriSign uses it and IE5 only recognises this form. Document 'x509'
98 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
99 without disallowing inline assembler and the like for non-pedantic builds.
102 *) Support Borland C++ builder.
103 [Janez Jere <jj@void.si>, modified by Ulf Möller]
108 *) SHA-1 cleanups and performance enhancements.
109 [Andy Polyakov <appro@fy.chalmers.se>]
111 *) Sparc v8plus assembler for the bignum library.
112 [Andy Polyakov <appro@fy.chalmers.se>]
114 *) Accept any -xxx and +xxx compiler options in Configure.
117 *) Update HPUX configuration.
120 *) Add missing sk_<type>_unshift() function to safestack.h
121 [Ralf S. Engelschall]
123 *) New function SSL_CTX_use_certificate_chain_file that sets the
124 "extra_cert"s in addition to the certificate. (This makes sense
125 only for "PEM" format files, as chains as a whole are not
129 *) Support verify_depth from the SSL API.
130 x509_vfy.c had what can be considered an off-by-one-error:
131 Its depth (which was not part of the external interface)
132 was actually counting the number of certificates in a chain;
133 now it really counts the depth.
136 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
137 instead of X509err, which often resulted in confusing error
138 messages since the error codes are not globally unique
139 (e.g. an alleged error in ssl3_accept when a certificate
140 didn't match the private key).
142 *) New function SSL_CTX_set_session_id_context that allows to set a default
143 value (so that you don't need SSL_set_session_id_context for each
144 connection using the SSL_CTX).
147 *) OAEP decoding bug fix.
150 *) Support INSTALL_PREFIX for package builders, as proposed by
154 *) New Configure options "threads" and "no-threads". For systems
155 where the proper compiler options are known (currently Solaris
156 and Linux), "threads" is the default.
159 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
162 *) Install various scripts to $(OPENSSLDIR)/misc, not to
163 $(INSTALLTOP)/bin -- they shouldn't clutter directories
164 such as /usr/local/bin.
167 *) "make linux-shared" to build shared libraries.
168 [Niels Poppe <niels@netbox.org>]
170 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
173 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
174 extension adding in x509 utility.
177 *) Remove NOPROTO sections and error code comments.
180 *) Partial rewrite of the DEF file generator to now parse the ANSI
184 *) New Configure options --prefix=DIR and --openssldir=DIR.
187 *) Complete rewrite of the error code script(s). It is all now handled
188 by one script at the top level which handles error code gathering,
189 header rewriting and C source file generation. It should be much better
190 than the old method: it now uses a modified version of Ulf's parser to
191 read the ANSI prototypes in all header files (thus the old K&R definitions
192 aren't needed for error creation any more) and do a better job of
193 translating function codes into names. The old 'ASN1 error code imbedded
194 in a comment' is no longer necessary and it doesn't use .err files which
195 have now been deleted. Also the error code call doesn't have to appear all
196 on one line (which resulted in some large lines...).
199 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
202 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
203 0 (which usually indicates a closed connection), but continue reading.
206 *) Fix some race conditions.
209 *) Add support for CRL distribution points extension. Add Certificate
210 Policies and CRL distribution points documentation.
213 *) Move the autogenerated header file parts to crypto/opensslconf.h.
216 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
217 8 of keying material. Merlin has also confirmed interop with this fix
218 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
219 [Merlin Hughes <merlin@baltimore.ie>]
221 *) Fix lots of warnings.
222 [Richard Levitte <levitte@stacken.kth.se>]
224 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
225 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
226 [Richard Levitte <levitte@stacken.kth.se>]
228 *) Fix problems with sizeof(long) == 8.
229 [Andy Polyakov <appro@fy.chalmers.se>]
231 *) Change functions to ANSI C.
234 *) Fix typos in error codes.
235 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
237 *) Remove defunct assembler files from Configure.
240 *) SPARC v8 assembler BIGNUM implementation.
241 [Andy Polyakov <appro@fy.chalmers.se>]
243 *) Support for Certificate Policies extension: both print and set.
244 Various additions to support the r2i method this uses.
247 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
248 return a const string when you are expecting an allocated buffer.
251 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
252 types DirectoryString and DisplayText.
255 *) Add code to allow r2i extensions to access the configuration database,
256 add an LHASH database driver and add several ctx helper functions.
259 *) Fix an evil bug in bn_expand2() which caused various BN functions to
260 fail when they extended the size of a BIGNUM.
263 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
264 support typesafe stack.
267 *) Fix typo in SSL_[gs]et_options().
268 [Nils Frostberg <nils@medcom.se>]
270 *) Delete various functions and files that belonged to the (now obsolete)
271 old X509V3 handling code.
274 *) New Configure option "rsaref".
277 *) Don't auto-generate pem.h.
280 *) Introduce type-safe ASN.1 SETs.
283 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
284 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
286 *) Introduce type-safe STACKs. This will almost certainly break lots of code
287 that links with OpenSSL (well at least cause lots of warnings), but fear
288 not: the conversion is trivial, and it eliminates loads of evil casts. A
289 few STACKed things have been converted already. Feel free to convert more.
290 In the fullness of time, I'll do away with the STACK type altogether.
293 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
294 specified in <certfile> by updating the entry in the index.txt file.
295 This way one no longer has to edit the index.txt file manually for
296 revoking a certificate. The -revoke option does the gory details now.
297 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
299 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
300 `-text' option at all and this way the `-noout -text' combination was
301 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
302 [Ralf S. Engelschall]
304 *) Make sure a corresponding plain text error message exists for the
305 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
306 verify callback function determined that a certificate was revoked.
307 [Ralf S. Engelschall]
309 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
310 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
311 all available cipers including rc5, which was forgotten until now.
312 In order to let the testing shell script know which algorithms
313 are available, a new (up to now undocumented) command
314 "openssl list-cipher-commands" is used.
317 *) Bugfix: s_client occasionally would sleep in select() when
318 it should have checked SSL_pending() first.
321 *) New functions DSA_do_sign and DSA_do_verify to provide access to
322 the raw DSA values prior to ASN.1 encoding.
325 *) Tweaks to Configure
326 Niels Poppe <niels@netbox.org>
328 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
332 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
335 *) New config option to avoid instructions that are illegal on the 80386.
336 The default code is faster, but requires at least a 486.
339 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
340 SSL2_SERVER_VERSION (not used at all) macros, which are now the
341 same as SSL2_VERSION anyway.
344 *) New "-showcerts" option for s_client.
347 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
348 application. Various cleanups and fixes.
351 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
352 modify error routines to work internally. Add error codes and PBE init
353 to library startup routines.
356 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
357 packing functions to asn1 and evp. Changed function names and error
361 *) PKCS12 integration: and so it begins... First of several patches to
362 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
366 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
367 and display support for Thawte strong extranet extension.
370 *) Add LinuxPPC support.
371 [Jeff Dubrule <igor@pobox.org>]
373 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
374 bn_div_words in alpha.s.
375 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
377 *) Make sure the RSA OAEP test is skipped under -DRSAref because
378 OAEP isn't supported when OpenSSL is built with RSAref.
379 [Ulf Moeller <ulf@fitug.de>]
381 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
382 so they no longer are missing under -DNOPROTO.
383 [Soren S. Jorvang <soren@t.dk>]
386 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
388 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
389 doesn't work when the session is reused. Coming soon!
392 *) Fix a security hole, that allows sessions to be reused in the wrong
393 context thus bypassing client cert protection! All software that uses
394 client certs and session caches in multiple contexts NEEDS PATCHING to
395 allow session reuse! A fuller solution is in the works.
396 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
398 *) Some more source tree cleanups (removed obsolete files
399 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
400 permission on "config" script to be executable) and a fix for the INSTALL
402 [Ulf Moeller <ulf@fitug.de>]
404 *) Remove some legacy and erroneous uses of malloc, free instead of
406 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
408 *) Make rsa_oaep_test return non-zero on error.
409 [Ulf Moeller <ulf@fitug.de>]
411 *) Add support for native Solaris shared libraries. Configure
412 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
413 if someone would make that last step automatic.
414 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
416 *) ctx_size was not built with the right compiler during "make links". Fixed.
419 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
420 except NULL ciphers". This means the default cipher list will no longer
421 enable NULL ciphers. They need to be specifically enabled e.g. with
422 the string "DEFAULT:eNULL".
425 *) Fix to RSA private encryption routines: if p < q then it would
426 occasionally produce an invalid result. This will only happen with
427 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
430 *) Be less restrictive and allow also `perl util/perlpath.pl
431 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
432 because this way one can also use an interpreter named `perl5' (which is
433 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
434 installed as `perl').
435 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
437 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
438 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
440 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
441 advapi32.lib to Win32 build and change the pem test comparision
442 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
443 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
444 and crypto/des/ede_cbcm_enc.c.
447 *) DES quad checksum was broken on big-endian architectures. Fixed.
450 *) Comment out two functions in bio.h that aren't implemented. Fix up the
451 Win32 test batch file so it (might) work again. The Win32 test batch file
452 is horrible: I feel ill....
455 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
456 in e_os.h. Audit of header files to check ANSI and non ANSI
457 sections: 10 functions were absent from non ANSI section and not exported
458 from Windows DLLs. Fixed up libeay.num for new functions.
461 *) Make `openssl version' output lines consistent.
462 [Ralf S. Engelschall]
464 *) Fix Win32 symbol export lists for BIO functions: Added
465 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
466 to ms/libeay{16,32}.def.
467 [Ralf S. Engelschall]
469 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
470 fine under Unix and passes some trivial tests I've now added. But the
471 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
472 added to make sure no one expects that this stuff really works in the
473 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
474 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
476 [Ralf S. Engelschall]
478 *) Fix the generation of two part addresses in perl.
479 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
481 *) Add config entry for Linux on MIPS.
482 [John Tobey <jtobey@channel1.com>]
484 *) Make links whenever Configure is run, unless we are on Windoze.
487 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
488 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
492 *) Add a useful kludge to allow package maintainers to specify compiler and
493 other platforms details on the command line without having to patch the
494 Configure script everytime: One now can use ``perl Configure
495 <id>:<details>'', i.e. platform ids are allowed to have details appended
496 to them (seperated by colons). This is treated as there would be a static
497 pre-configured entry in Configure's %table under key <id> with value
498 <details> and ``perl Configure <id>'' is called. So, when you want to
499 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
500 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
501 now, which overrides the FreeBSD-elf entry on-the-fly.
502 [Ralf S. Engelschall]
504 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
507 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
508 on the `perl Configure ...' command line. This way one can compile
509 OpenSSL libraries with Position Independent Code (PIC) which is needed
510 for linking it into DSOs.
511 [Ralf S. Engelschall]
513 *) Remarkably, export ciphers were totally broken and no-one had noticed!
517 *) Cleaned up the LICENSE document: The official contact for any license
518 questions now is the OpenSSL core team under openssl-core@openssl.org.
519 And add a paragraph about the dual-license situation to make sure people
520 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
521 to the OpenSSL toolkit.
522 [Ralf S. Engelschall]
524 *) General source tree makefile cleanups: Made `making xxx in yyy...'
525 display consistent in the source tree and replaced `/bin/rm' by `rm'.
526 Additonally cleaned up the `make links' target: Remove unnecessary
527 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
528 to speed processing and no longer clutter the display with confusing
529 stuff. Instead only the actually done links are displayed.
530 [Ralf S. Engelschall]
532 *) Permit null encryption ciphersuites, used for authentication only. It used
533 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
534 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
538 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
539 signed attributes when verifying signatures (this would break them),
540 the detached data encoding was wrong and public keys obtained using
541 X509_get_pubkey() weren't freed.
544 *) Add text documentation for the BUFFER functions. Also added a work around
545 to a Win95 console bug. This was triggered by the password read stuff: the
546 last character typed gets carried over to the next fread(). If you were
547 generating a new cert request using 'req' for example then the last
548 character of the passphrase would be CR which would then enter the first
552 *) Added the new `Includes OpenSSL Cryptography Software' button as
553 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
554 button and can be used by applications based on OpenSSL to show the
555 relationship to the OpenSSL project.
556 [Ralf S. Engelschall]
558 *) Remove confusing variables in function signatures in files
559 ssl/ssl_lib.c and ssl/ssl.h.
560 [Lennart Bong <lob@kulthea.stacken.kth.se>]
562 *) Don't install bss_file.c under PREFIX/include/
563 [Lennart Bong <lob@kulthea.stacken.kth.se>]
565 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
566 functions that return function pointers and has support for NT specific
567 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
568 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
569 unsigned to signed types: this was killing the Win32 compile.
572 *) Add new certificate file to stack functions,
573 SSL_add_dir_cert_subjects_to_stack() and
574 SSL_add_file_cert_subjects_to_stack(). These largely supplant
575 SSL_load_client_CA_file(), and can be used to add multiple certs easily
576 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
577 This means that Apache-SSL and similar packages don't have to mess around
578 to add as many CAs as they want to the preferred list.
581 *) Experiment with doxygen documentation. Currently only partially applied to
583 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
584 openssl.doxy as the configuration file.
587 *) Get rid of remaining C++-style comments which strict C compilers hate.
588 [Ralf S. Engelschall, pointed out by Carlos Amengual]
590 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
591 compiled in by default: it has problems with large keys.
594 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
595 DH private keys and/or callback functions which directly correspond to
596 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
597 is needed for applications which have to configure certificates on a
598 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
600 For the RSA certificate situation is makes no difference, but
601 for the DSA certificate situation this fixes the "no shared cipher"
602 problem where the OpenSSL cipher selection procedure failed because the
603 temporary keys were not overtaken from the context and the API provided
604 no way to reconfigure them.
605 The new functions now let applications reconfigure the stuff and they
606 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
607 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
608 non-public-API function ssl_cert_instantiate() is used as a helper
609 function and also to reduce code redundancy inside ssl_rsa.c.
610 [Ralf S. Engelschall]
612 *) Move s_server -dcert and -dkey options out of the undocumented feature
613 area because they are useful for the DSA situation and should be
614 recognized by the users.
615 [Ralf S. Engelschall]
617 *) Fix the cipher decision scheme for export ciphers: the export bits are
618 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
619 SSL_EXP_MASK. So, the original variable has to be used instead of the
620 already masked variable.
621 [Richard Levitte <levitte@stacken.kth.se>]
623 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
624 [Richard Levitte <levitte@stacken.kth.se>]
626 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
627 from `int' to `unsigned int' because it's a length and initialized by
628 EVP_DigestFinal() which expects an `unsigned int *'.
629 [Richard Levitte <levitte@stacken.kth.se>]
631 *) Don't hard-code path to Perl interpreter on shebang line of Configure
632 script. Instead use the usual Shell->Perl transition trick.
633 [Ralf S. Engelschall]
635 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
636 (in addition to RSA certificates) to match the behaviour of `openssl dsa
637 -noout -modulus' as it's already the case for `openssl rsa -noout
638 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
639 currently the public key is printed (a decision which was already done by
640 `openssl dsa -modulus' in the past) which serves a similar purpose.
641 Additionally the NO_RSA no longer completely removes the whole -modulus
642 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
644 [Ralf S. Engelschall]
646 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
647 BIO. See the source (crypto/evp/bio_ok.c) for more info.
648 [Arne Ansper <arne@ats.cyber.ee>]
650 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
651 to be added. Now both 'req' and 'ca' can use new objects defined in the
655 *) Add cool BIO that does syslog (or event log on NT).
656 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
658 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
659 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
660 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
661 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
664 *) Add preliminary config info for new extension code.
667 *) Make RSA_NO_PADDING really use no padding.
668 [Ulf Moeller <ulf@fitug.de>]
670 *) Generate errors when private/public key check is done.
673 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
674 for some CRL extensions and new objects added.
677 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
678 key usage extension and fuller support for authority key id.
681 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
682 padding method for RSA, which is recommended for new applications in PKCS
683 #1 v2.0 (RFC 2437, October 1998).
684 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
685 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
686 against Bleichbacher's attack on RSA.
687 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
690 *) Updates to the new SSL compression code
691 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
693 *) Fix so that the version number in the master secret, when passed
694 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
695 (because the server will not accept higher), that the version number
696 is 0x03,0x01, not 0x03,0x00
697 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
699 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
700 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
701 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
704 *) Support for RAW extensions where an arbitrary extension can be
705 created by including its DER encoding. See apps/openssl.cnf for
709 *) Make sure latest Perl versions don't interpret some generated C array
710 code as Perl array code in the crypto/err/err_genc.pl script.
711 [Lars Weber <3weber@informatik.uni-hamburg.de>]
713 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
714 not many people have the assembler. Various Win32 compilation fixes and
715 update to the INSTALL.W32 file with (hopefully) more accurate Win32
719 *) Modify configure script 'Configure' to automatically create crypto/date.h
720 file under Win32 and also build pem.h from pem.org. New script
721 util/mkfiles.pl to create the MINFO file on environments that can't do a
722 'make files': perl util/mkfiles.pl >MINFO should work.
725 *) Major rework of DES function declarations, in the pursuit of correctness
726 and purity. As a result, many evil casts evaporated, and some weirdness,
727 too. You may find this causes warnings in your code. Zapping your evil
728 casts will probably fix them. Mostly.
731 *) Fix for a typo in asn1.h. Bug fix to object creation script
732 obj_dat.pl. It considered a zero in an object definition to mean
733 "end of object": none of the objects in objects.h have any zeros
734 so it wasn't spotted.
735 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
737 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
738 Masking (CBCM). In the absence of test vectors, the best I have been able
739 to do is check that the decrypt undoes the encrypt, so far. Send me test
740 vectors if you have them.
743 *) Correct calculation of key length for export ciphers (too much space was
744 allocated for null ciphers). This has not been tested!
747 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
748 message is now correct (it understands "crypto" and "ssl" on its
749 command line). There is also now an "update" option. This will update
750 the util/ssleay.num and util/libeay.num files with any new functions.
752 perl util/mkdef.pl crypto ssl update
756 *) Overhauled the Perl interface (perl/*):
757 - ported BN stuff to OpenSSL's different BN library
758 - made the perl/ source tree CVS-aware
759 - renamed the package from SSLeay to OpenSSL (the files still contain
760 their history because I've copied them in the repository)
761 - removed obsolete files (the test scripts will be replaced
762 by better Test::Harness variants in the future)
763 [Ralf S. Engelschall]
765 *) First cut for a very conservative source tree cleanup:
766 1. merge various obsolete readme texts into doc/ssleay.txt
767 where we collect the old documents and readme texts.
768 2. remove the first part of files where I'm already sure that we no
769 longer need them because of three reasons: either they are just temporary
770 files which were left by Eric or they are preserved original files where
771 I've verified that the diff is also available in the CVS via "cvs diff
772 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
773 the crypto/md/ stuff).
774 [Ralf S. Engelschall]
776 *) More extension code. Incomplete support for subject and issuer alt
777 name, issuer and authority key id. Change the i2v function parameters
778 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
779 what that's for :-) Fix to ASN1 macro which messed up
780 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
783 *) Preliminary support for ENUMERATED type. This is largely copied from the
787 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
788 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
790 *) Make sure `make rehash' target really finds the `openssl' program.
791 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
793 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
794 like to hear about it if this slows down other processors.
797 *) Add CygWin32 platform information to Configure script.
798 [Alan Batie <batie@aahz.jf.intel.com>]
800 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
801 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
803 *) New program nseq to manipulate netscape certificate sequences
806 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
810 *) Fixes to BN code. Previously the default was to define BN_RECURSION
811 but the BN code had some problems that would cause failures when
812 doing certificate verification and some other functions.
813 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
815 *) Add ASN1 and PEM code to support netscape certificate sequences.
818 *) Add ASN1 and PEM code to support netscape certificate sequences.
821 *) Add several PKIX and private extended key usage OIDs.
824 *) Modify the 'ca' program to handle the new extension code. Modify
825 openssl.cnf for new extension format, add comments.
828 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
829 and add a sample to openssl.cnf so req -x509 now adds appropriate
833 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
834 error code, add initial support to X509_print() and x509 application.
837 *) Takes a deep breath and start addding X509 V3 extension support code. Add
838 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
839 stuff is currently isolated and isn't even compiled yet.
842 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
843 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
844 Removed the versions check from X509 routines when loading extensions:
845 this allows certain broken certificates that don't set the version
846 properly to be processed.
849 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
850 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
851 can still be regenerated with "make depend".
854 *) Spelling mistake in C version of CAST-128.
855 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
857 *) Changes to the error generation code. The perl script err-code.pl
858 now reads in the old error codes and retains the old numbers, only
859 adding new ones if necessary. It also only changes the .err files if new
860 codes are added. The makefiles have been modified to only insert errors
861 when needed (to avoid needlessly modifying header files). This is done
862 by only inserting errors if the .err file is newer than the auto generated
863 C file. To rebuild all the error codes from scratch (the old behaviour)
864 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
865 or delete all the .err files.
868 *) CAST-128 was incorrectly implemented for short keys. The C version has
869 been fixed, but is untested. The assembler versions are also fixed, but
870 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
871 to regenerate it if needed.
872 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
873 Hagino <itojun@kame.net>]
875 *) File was opened incorrectly in randfile.c.
876 [Ulf Möller <ulf@fitug.de>]
878 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
879 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
880 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
881 al: it's just almost always a UTCTime. Note this patch adds new error
882 codes so do a "make errors" if there are problems.
885 *) Correct Linux 1 recognition in config.
886 [Ulf Möller <ulf@fitug.de>]
888 *) Remove pointless MD5 hash when using DSA keys in ca.
889 [Anonymous <nobody@replay.com>]
891 *) Generate an error if given an empty string as a cert directory. Also
892 generate an error if handed NULL (previously returned 0 to indicate an
893 error, but didn't set one).
894 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
896 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
899 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
900 parameters. This was causing a warning which killed off the Win32 compile.
903 *) Remove C++ style comments from crypto/bn/bn_local.h.
904 [Neil Costigan <neil.costigan@celocom.com>]
906 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
907 based on a text string, looking up short and long names and finally
908 "dot" format. The "dot" format stuff didn't work. Added new function
909 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
910 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
911 OID is not part of the table.
914 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
915 X509_LOOKUP_by_alias().
918 *) Sort openssl functions by name.
921 *) Get the gendsa program working (hopefully) and add it to app list. Remove
922 encryption from sample DSA keys (in case anyone is interested the password
926 *) Make _all_ *_free functions accept a NULL pointer.
927 [Frans Heymans <fheymans@isaserver.be>]
929 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
931 [Anonymous <nobody@replay.com>]
933 *) s_server should send the CAfile as acceptable CAs, not its own cert.
934 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
936 *) Don't blow it for numeric -newkey arguments to apps/req.
937 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
939 *) Temp key "for export" tests were wrong in s3_srvr.c.
940 [Anonymous <nobody@replay.com>]
942 *) Add prototype for temp key callback functions
943 SSL_CTX_set_tmp_{rsa,dh}_callback().
946 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
947 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
950 *) X509_name_add_entry() freed the wrong thing after an error.
951 [Arne Ansper <arne@ats.cyber.ee>]
953 *) rsa_eay.c would attempt to free a NULL context.
954 [Arne Ansper <arne@ats.cyber.ee>]
956 *) BIO_s_socket() had a broken should_retry() on Windoze.
957 [Arne Ansper <arne@ats.cyber.ee>]
959 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
960 [Arne Ansper <arne@ats.cyber.ee>]
962 *) Make sure the already existing X509_STORE->depth variable is initialized
963 in X509_STORE_new(), but document the fact that this variable is still
964 unused in the certificate verification process.
965 [Ralf S. Engelschall]
967 *) Fix the various library and apps files to free up pkeys obtained from
968 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
971 *) Fix reference counting in X509_PUBKEY_get(). This makes
972 demos/maurice/example2.c work, amongst others, probably.
973 [Steve Henson and Ben Laurie]
975 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
976 `openssl' and second, the shortcut symlinks for the `openssl <command>'
977 are no longer created. This way we have a single and consistent command
978 line interface `openssl <command>', similar to `cvs <command>'.
979 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
981 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
982 BIT STRING wrapper always have zero unused bits.
985 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
988 *) Make the top-level INSTALL documentation easier to understand.
991 *) Makefiles updated to exit if an error occurs in a sub-directory
992 make (including if user presses ^C) [Paul Sutton]
994 *) Make Montgomery context stuff explicit in RSA data structure.
997 *) Fix build order of pem and err to allow for generated pem.h.
1000 *) Fix renumbering bug in X509_NAME_delete_entry().
1003 *) Enhanced the err-ins.pl script so it makes the error library number
1004 global and can add a library name. This is needed for external ASN1 and
1005 other error libraries.
1008 *) Fixed sk_insert which never worked properly.
1011 *) Fix ASN1 macros so they can handle indefinite length construted
1012 EXPLICIT tags. Some non standard certificates use these: they can now
1016 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1017 into a single doc/ssleay.txt bundle. This way the information is still
1018 preserved but no longer messes up this directory. Now it's new room for
1019 the new set of documenation files.
1020 [Ralf S. Engelschall]
1022 *) SETs were incorrectly DER encoded. This was a major pain, because they
1023 shared code with SEQUENCEs, which aren't coded the same. This means that
1024 almost everything to do with SETs or SEQUENCEs has either changed name or
1025 number of arguments.
1026 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1028 *) Fix test data to work with the above.
1031 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1032 was already fixed by Eric for 0.9.1 it seems.
1033 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1035 *) Autodetect FreeBSD3.
1038 *) Fix various bugs in Configure. This affects the following platforms:
1042 unixware-2.0-pentium
1046 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1047 before they are needed.
1050 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1054 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1056 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1057 changed SSLeay to OpenSSL in version strings.
1058 [Ralf S. Engelschall]
1060 *) Some fixups to the top-level documents.
1063 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1064 because the symlink to include/ was missing.
1065 [Ralf S. Engelschall]
1067 *) Incorporated the popular no-RSA/DSA-only patches
1068 which allow to compile a RSA-free SSLeay.
1069 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1071 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1072 when "ssleay" is still not found.
1073 [Ralf S. Engelschall]
1075 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1076 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1078 *) Updated the README file.
1079 [Ralf S. Engelschall]
1081 *) Added various .cvsignore files in the CVS repository subdirs
1082 to make a "cvs update" really silent.
1083 [Ralf S. Engelschall]
1085 *) Recompiled the error-definition header files and added
1086 missing symbols to the Win32 linker tables.
1087 [Ralf S. Engelschall]
1089 *) Cleaned up the top-level documents;
1090 o new files: CHANGES and LICENSE
1091 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1092 o merged COPYRIGHT into LICENSE
1093 o removed obsolete TODO file
1094 o renamed MICROSOFT to INSTALL.W32
1095 [Ralf S. Engelschall]
1097 *) Removed dummy files from the 0.9.1b source tree:
1098 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1099 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

1102 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1103 [Ralf S. Engelschall]
1105 *) Added various platform portability fixes.
1108 *) The Genesis of the OpenSSL rpject:
1109 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1110 Young and Tim J. Hudson created while they were working for C2Net until
1112 [The OpenSSL Project]
1115 Changes between 0.9.0b and 0.9.1b [not released]
1117 *) Updated a few CA certificates under certs/
1120 *) Changed some BIGNUM api stuff.
1123 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1124 DGUX x86, Linux Alpha, etc.
1127 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1128 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1132 *) Add -strparse option to asn1pars program which parses nested
1134 [Dr Stephen Henson <shenson@bigfoot.com>]
1136 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1139 *) DSA fix for "ca" program.
1142 *) Added "-genkey" option to "dsaparam" program.
1145 *) Added RIPE MD160 (rmd160) message digest.
1148 *) Added -a (all) option to "ssleay version" command.
1151 *) Added PLATFORM define which is the id given to Configure.
1154 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1157 *) Extended the ASN.1 parser routines.
1160 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1163 *) Added a BN_CTX to the BN library.
1166 *) Fixed the weak key values in DES library
1169 *) Changed API in EVP library for cipher aliases.
1172 *) Added support for RC2/64bit cipher.
1175 *) Converted the lhash library to the crypto/mem.c functions.
1178 *) Added more recognized ASN.1 object ids.
1181 *) Added more RSA padding checks for SSL/TLS.
1184 *) Added BIO proxy/filter functionality.
1187 *) Added extra_certs to SSL_CTX which can be used
1188 send extra CA certificates to the client in the CA cert chain sending
1189 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1192 *) Now Fortezza is denied in the authentication phase because
1193 this is key exchange mechanism is not supported by SSLeay at all.
1196 *) Additional PKCS1 checks.
1199 *) Support the string "TLSv1" for all TLS v1 ciphers.
1202 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1203 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1206 *) Fixed a few memory leaks.
1209 *) Fixed various code and comment typos.
1212 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1213 bytes sent in the client random.
1214 [Edward Bishop <ebishop@spyglass.com>]
