OpenSSL CHANGES
_______________
Changes between 0.9.1c and 0.9.2
*) Modify ms/do_ms.bat to not generate assembly language makefiles since
not many people have the assembler. Various Win32 compilation fixes and
update to the INSTALL.W32 file with (hopefully) more accurate Win32
build instructions.
[Steve Henson]
*) Modify configure script 'Configure' to automatically create crypto/date.h
file under Win32 and also build pem.h from pem.org. New script
util/mkfiles.pl to create the MINFO file on environments that can't do a
'make files': perl util/mkfiles.pl >MINFO should work.
[Steve Henson]
*) Major rework of DES function declarations, in the pursuit of correctness
and purity. As a result, many evil casts evaporated, and some weirdness,
too. You may find this causes warnings in your code. Zapping your evil
casts will probably fix them. Mostly.
[Ben Laurie]
*) Fix for a typo in asn1.h. Bug fix to object creation script
obj_dat.pl. It considered a zero in an object definition to mean
"end of object": none of the objects in objects.h have any zeros
so it wasn't spotted.
[Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
*) Add support for Triple DES Cipher Block Chaining with Output Feedback
Masking (CBCM). In the absence of test vectors, the best I have been able
to do is check that the decrypt undoes the encrypt, so far. Send me test
vectors if you have them.
[Ben Laurie]
*) Correct caclulation of key length for export ciphers (too much space was
allocated for null ciphers). This has not been tested!
[Ben Laurie]
*) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
message is now correct (it understands "crypto" and "ssl" on its
command line). There is also now an "update" option. This will update
the util/ssleay.num and util/libeay.num files with any new functions.
If you do a:
perl util/mkdef.pl crypto ssl update
it will update them.
[Steve Henson]
*) Overhauled the Perl interface (perl/*):
- ported BN stuff to OpenSSL's different BN library
- made the perl/ source tree CVS-aware
- renamed the package from SSLeay to OpenSSL (the files still contain
their history because I've copied them in the repository)
- removed obsolete files (the test scripts will be replaced
by better Test::Harness variants in the future)
[Ralf S. Engelschall]
*) First cut for a very conservative source tree cleanup:
1. merge various obsolete readme texts into doc/ssleay.txt
where we collect the old documents and readme texts.
2. remove the first part of files where I'm already sure that we no
longer need them because of three reasons: either they are just temporary
files which were left by Eric or they are preserved original files where
I've verified that the diff is also available in the CVS via "cvs diff
-rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
the crypto/md/ stuff).
[Ralf S. Engelschall]
*) More extension code. Incomplete support for subject and issuer alt
name, issuer and authority key id. Change the i2v function parameters
and add an extra 'crl' parameter in the X509V3_CTX structure: guess
what that's for :-) Fix to ASN1 macro which messed up
IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
[Steve Henson]
*) Preliminary support for ENUMERATED type. This is largely copied from the
INTEGER code.
[Steve Henson]
*) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
[Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
*) Make sure `make rehash' target really finds the `openssl' program.
[Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
*) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
like to hear about it if this slows down other processors.
[Ben Laurie]
*) Add CygWin32 platform information to Configure script.
[Alan Batie <batie@aahz.jf.intel.com>]
*) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
[Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
*) New program nseq to manipulate netscape certificate sequences
[Steve Henson]
*) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
few typos.
[Steve Henson]
*) Fixes to BN code. Previously the default was to define BN_RECURSION
but the BN code had some problems that would cause failures when
doing certificate verification and some other functions.
[Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
*) Add ASN1 and PEM code to support netscape certificate sequences.
[Steve Henson]
*) Add ASN1 and PEM code to support netscape certificate sequences.
[Steve Henson]
*) Add several PKIX and private extended key usage OIDs.
[Steve Henson]
*) Modify the 'ca' program to handle the new extension code. Modify
openssl.cnf for new extension format, add comments.
[Steve Henson]
*) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
and add a sample to openssl.cnf so req -x509 now adds appropriate
CA extensions.
[Steve Henson]
*) Continued X509 V3 changes. Add to other makefiles, integrate with the
error code, add initial support to X509_print() and x509 application.
[Steve Henson]
*) Takes a deep breath and start addding X509 V3 extension support code. Add
files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
stuff is currently isolated and isn't even compiled yet.
[Steve Henson]
*) Continuing patches for GeneralizedTime. Fix up certificate and CRL
ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
Removed the versions check from X509 routines when loading extensions:
this allows certain broken certificates that don't set the version
properly to be processed.
[Steve Henson]
*) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
can still be regenerated with "make depend".
[Ben Laurie]
*) Spelling mistake in C version of CAST-128.
[Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
*) Changes to the error generation code. The perl script err-code.pl
now reads in the old error codes and retains the old numbers, only
adding new ones if necessary. It also only changes the .err files if new
codes are added. The makefiles have been modified to only insert errors
when needed (to avoid needlessly modifying header files). This is done
by only inserting errors if the .err file is newer than the auto generated
C file. To rebuild all the error codes from scratch (the old behaviour)
either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
or delete all the .err files.
[Steve Henson]
*) CAST-128 was incorrectly implemented for short keys. The C version has
been fixed, but is untested. The assembler versions are also fixed, but
new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
to regenerate it if needed.
[Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
Hagino <itojun@kame.net>]
*) File was opened incorrectly in randfile.c.
[Ulf M<>ller <ulf@fitug.de>]
*) Beginning of support for GeneralizedTime. d2i, i2d, check and print
functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
GeneralizedTime. ASN1_TIME is the proper type used in certificates et
al: it's just almost always a UTCTime. Note this patch adds new error
codes so do a "make errors" if there are problems.
[Steve Henson]
*) Correct Linux 1 recognition in config.
[Ulf M<>ller <ulf@fitug.de>]
*) Remove pointless MD5 hash when using DSA keys in ca.
[Anonymous <nobody@replay.com>]
*) Generate an error if given an empty string as a cert directory. Also
generate an error if handed NULL (previously returned 0 to indicate an
error, but didn't set one).
[Ben Laurie, reported by Anonymous <nobody@replay.com>]
*) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
[Ben Laurie]
*) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
parameters. This was causing a warning which killed off the Win32 compile.
[Steve Henson]
*) Remove C++ style comments from crypto/bn/bn_local.h.
[Neil Costigan <neil.costigan@celocom.com>]
*) The function OBJ_txt2nid was broken. It was supposed to return a nid
based on a text string, looking up short and long names and finally
"dot" format. The "dot" format stuff didn't work. Added new function
OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
OID is not part of the table.
[Steve Henson]
*) Add prototypes to X509 lookup/verify methods, fixing a bug in
X509_LOOKUP_by_alias().
[Ben Laurie]
*) Sort openssl functions by name.
[Ben Laurie]
*) Get the gendsa program working (hopefully) and add it to app list. Remove
encryption from sample DSA keys (in case anyone is interested the password
was "1234").
[Steve Henson]
*) Make _all_ *_free functions accept a NULL pointer.
[Frans Heymans <fheymans@isaserver.be>]
*) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
NULL pointers.
[Anonymous <nobody@replay.com>]
*) s_server should send the CAfile as acceptable CAs, not its own cert.
[Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
*) Don't blow it for numeric -newkey arguments to apps/req.
[Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
*) Temp key "for export" tests were wrong in s3_srvr.c.
[Anonymous <nobody@replay.com>]
*) Add prototype for temp key callback functions
SSL_CTX_set_tmp_{rsa,dh}_callback().
[Ben Laurie]
*) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
[Steve Henson]
*) X509_name_add_entry() freed the wrong thing after an error.
[Arne Ansper <arne@ats.cyber.ee>]
*) rsa_eay.c would attempt to free a NULL context.
[Arne Ansper <arne@ats.cyber.ee>]
*) BIO_s_socket() had a broken should_retry() on Windoze.
[Arne Ansper <arne@ats.cyber.ee>]
*) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
[Arne Ansper <arne@ats.cyber.ee>]
*) Make sure the already existing X509_STORE->depth variable is initialized
in X509_STORE_new(), but document the fact that this variable is still
unused in the certificate verification process.
[Ralf S. Engelschall]
*) Fix the various library and apps files to free up pkeys obtained from
X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
[Steve Henson]
*) Fix reference counting in X509_PUBKEY_get(). This makes
demos/maurice/example2.c work, amongst others, probably.
[Steve Henson and Ben Laurie]
*) First cut of a cleanup for apps/. First the `ssleay' program is now named
`openssl' and second, the shortcut symlinks for the `openssl <command>'
are no longer created. This way we have a single and consistent command
line interface `openssl <command>', similar to `cvs <command>'.
[Ralf S. Engelschall, Paul Sutton and Ben Laurie]
*) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
BIT STRING wrapper always have zero unused bits.
[Steve Henson]
*) Add CA.pl, perl version of CA.sh, add extended key usage OID.
[Steve Henson]
*) Make the top-level INSTALL documentation easier to understand.
[Paul Sutton]
*) Makefiles updated to exit if an error occurs in a sub-directory
make (including if user presses ^C) [Paul Sutton]
*) Make Montgomery context stuff explicit in RSA data structure.
[Ben Laurie]
*) Fix build order of pem and err to allow for generated pem.h.
[Ben Laurie]
*) Fix renumbering bug in X509_NAME_delete_entry().
[Ben Laurie]
*) Enhanced the err-ins.pl script so it makes the error library number
global and can add a library name. This is needed for external ASN1 and
other error libraries.
[Steve Henson]
*) Fixed sk_insert which never worked properly.
[Steve Henson]
*) Fix ASN1 macros so they can handle indefinite length construted
EXPLICIT tags. Some non standard certificates use these: they can now
be read in.
[Steve Henson]
*) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
into a single doc/ssleay.txt bundle. This way the information is still
preserved but no longer messes up this directory. Now it's new room for
the new set of documenation files.
[Ralf S. Engelschall]
*) SETs were incorrectly DER encoded. This was a major pain, because they
shared code with SEQUENCEs, which aren't coded the same. This means that
almost everything to do with SETs or SEQUENCEs has either changed name or
number of arguments.
[Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
*) Fix test data to work with the above.
[Ben Laurie]
*) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
was already fixed by Eric for 0.9.1 it seems.
[Ben Laurie - pointed out by Ulf M<>ller <ulf@fitug.de>]
*) Autodetect FreeBSD3.
[Ben Laurie]
*) Fix various bugs in Configure. This affects the following platforms:
nextstep
ncr-scde
unixware-2.0
unixware-2.0-pentium
sco5-cc.
[Ben Laurie]
*) Eliminate generated files from CVS. Reorder tests to regenerate files
before they are needed.
[Ben Laurie]
*) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
[Ben Laurie]
Changes between 0.9.1b and 0.9.1c
*) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
changed SSLeay to OpenSSL in version strings.
[Ralf S. Engelschall]
*) Some fixups to the top-level documents.
[Paul Sutton]
*) Fixed the nasty bug where rsaref.h was not found under compile-time
because the symlink to include/ was missing.
[Ralf S. Engelschall]
*) Incorporated the popular no-RSA/DSA-only patches
which allow to compile a RSA-free SSLeay.
[Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
*) Fixed nasty rehash problem under `make -f Makefile.ssl links'
when "ssleay" is still not found.
[Ralf S. Engelschall]
*) Added more platforms to Configure: Cray T3E, HPUX 11,
[Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
*) Updated the README file.
[Ralf S. Engelschall]
*) Added various .cvsignore files in the CVS repository subdirs
to make a "cvs update" really silent.
[Ralf S. Engelschall]
*) Recompiled the error-definition header files and added
missing symbols to the Win32 linker tables.
[Ralf S. Engelschall]
*) Cleaned up the top-level documents;
o new files: CHANGES and LICENSE
o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
o merged COPYRIGHT into LICENSE
o removed obsolete TODO file
o renamed MICROSOFT to INSTALL.W32
[Ralf S. Engelschall]
*) Removed dummy files from the 0.9.1b source tree:
crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
[Ralf S. Engelschall]
*) Added various platform portability fixes.
[Mark J. Cox]
*) The Genesis of the OpenSSL rpject:
We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
Young and Tim J. Hudson created while they were working for C2Net until
summer 1998.
[The OpenSSL Project]
Changes between 0.9.0b and 0.9.1b
*) Updated a few CA certificates under certs/

[Eric A. Young]
*) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
DGUX x86, Linux Alpha, etc.
[Eric A. Young]
*) New COMP library [crypto/comp/] for SSL Record Layer Compression:
