CHANGES

  *) 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 Möller <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 Möller <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 Möller <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  [23-Dec-1998]

  *) 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.

     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

     [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.

     [Eric A. Young]

  *) Now Fortezza is denied in the authentication phase because
     this is key exchange mechanism is not supported by SSLeay at all.
     [Eric A. Young]
