Import of old SSLeay release: SSLeay 0.9.0b

[openssl.git] / HISTORY

16-Mar-98
        - Patch for Cray T90 from Wayne Schroeder <schroede@SDSC.EDU>
        - Lots and lots of changes

29-Jan-98
        - ASN1_BIT_STRING_set_bit()/ASN1_BIT_STRING_get_bit() from
          Goetz Babin-Ebell <babinebell@trustcenter.de>.
        - SSL_version() now returns SSL2_VERSION, SSL3_VERSION or
          TLS1_VERSION.

7-Jan-98
        - Finally reworked the cipher string to ciphers again, so it
          works correctly
        - All the app_data stuff is now ex_data with funcion calls to access.
          The index is supplied by a function and 'methods' can be setup
          for the types that are called on XXX_new/XXX_free.  This lets
          applications get notified on creation and destruction.  Some of
          the RSA methods could be implemented this way and I may do so.
        - Oh yes, SSL under perl5 is working at the basic level.

15-Dec-97
        - Warning - the gethostbyname cache is not fully thread safe,
          but it should work well enough.
        - Major internal reworking of the app_data stuff.  More functions
          but if you were accessing ->app_data directly, things will
          stop working.
        - The perlv5 stuff is working.  Currently on message digests,
          ciphers and the bignum library.

9-Dec-97
        - Modified re-negotiation so that server initated re-neg
          will cause a SSL_read() to return -1 should retry.
          The danger otherwise was that the server and the
          client could end up both trying to read when using non-blocking
          sockets.

4-Dec-97
        - Lots of small changes
        - Fix for binaray mode in Windows for the FILE BIO, thanks to
          Bob Denny <rdenny@dc3.com>

17-Nov-97
        - Quite a few internal cleanups, (removal of errno, and using macros
          defined in e_os.h).
        - A bug in ca.c, pointed out by yasuyuki-ito@d-cruise.co.jp, where
          the automactic naming out output files was being stuffed up.

29-Oct-97
        - The Cast5 cipher has been added.  MD5 and SHA-1 are now in assember
          for x86.

21-Oct-97
        - Fixed a bug in the BIO_gethostbyname() cache.

15-Oct-97
        - cbc mode for blowfish/des/3des is now in assember.  Blowfish asm
          has also been improved.  At this point in time, on the pentium,
          md5 is %80 faster, the unoptimesed sha-1 is %79 faster,
          des-cbc is %28 faster, des-ede3-cbc is %9 faster and blowfish-cbc
          is %62 faster.

12-Oct-97
        - MEM_BUF_grow() has been fixed so that it always sets the buf->length
          to the value we are 'growing' to.  Think of MEM_BUF_grow() as the
          way to set the length value correctly.

10-Oct-97
        - I now hash for certificate lookup on the raw DER encoded RDN (md5).
          This breaks things again :-(.  This is efficent since I cache
          the DER encoding of the RDN.
        - The text DN now puts in the numeric OID instead of UNKNOWN.
        - req can now process arbitary OIDs in the config file.
        - I've been implementing md5 in x86 asm, much faster :-).
        - Started sha1 in x86 asm, needs more work.
        - Quite a few speedups in the BN stuff.  RSA public operation
          has been made faster by caching the BN_MONT_CTX structure.
          The calulating of the Ai where A*Ai === 1 mod m was rather
          expensive.  Basically a 40-50% speedup on public operations.
          The RSA speedup is now 15% on pentiums and %20 on pentium
          pro.

30-Sep-97
        - After doing some profiling, I added x86 adm for bn_add_words(),
          which just adds 2 arrays of longs together.  A %10 speedup
          for 512 and 1024 bit RSA on the pentium pro.

29-Sep-97
        - Converted the x86 bignum assembler to us the perl scripts
          for generation.

23-Sep-97
        - If SSL_set_session() is passed a NULL session, it now clears the
          current session-id.

22-Sep-97
        - Added a '-ss_cert file' to apps/ca.c.  This will sign selfsigned
          certificates.
        - Bug in crypto/evp/encode.c where by decoding of 65 base64
          encoded lines, one line at a time (via a memory BIO) would report
          EOF after the first line was decoded.
        - Fix in X509_find_by_issuer_and_serial() from
          Dr Stephen Henson <shenson@bigfoot.com>

19-Sep-97
        - NO_FP_API and NO_STDIO added.
        - Put in sh config command.  It auto runs Configure with the correct
          parameters.

18-Sep-97
        - Fix x509.c so if a DSA cert has different parameters to its parent,
          they are left in place.  Not tested yet.

16-Sep-97
        - ssl_create_cipher_list() had some bugs, fixes from
          Patrick Eisenacher <eisenach@stud.uni-frankfurt.de>
        - Fixed a bug in the Base64 BIO, where it would return 1 instead
          of -1 when end of input was encountered but should retry.
          Basically a Base64/Memory BIO interaction problem.
        - Added a HMAC set of functions in preporarion for TLS work.

15-Sep-97
        - Top level makefile tweak - Cameron Simpson <cs@zip.com.au>
        - Prime generation spead up %25 (512 bit prime, pentium pro linux)
          by using montgomery multiplication in the prime number test.

11-Sep-97
        - Ugly bug in ssl3_write_bytes().  Basically if application land
          does a SSL_write(ssl,buf,len) where len > 16k, the SSLv3 write code
          did not check the size and tried to copy the entire buffer.
          This would tend to cause memory overwrites since SSLv3 has
          a maximum packet size of 16k.  If your program uses
          buffers <= 16k, you would probably never see this problem.
        - Fixed a new errors that were cause by malloc() not returning
          0 initialised memory..
        - SSL_OP_NETSCAPE_CA_DN_BUG was being switched on when using
          SSL_CTX_set_options(ssl_ctx,SSL_OP_ALL); which was a bad thing
          since this flags stops SSLeay being able to handle client
          cert requests correctly.

08-Sep-97
        - SSL_SESS_CACHE_NO_INTERNAL_LOOKUP option added.  When switched
          on, the SSL server routines will not use a SSL_SESSION that is
          held in it's cache.  This in intended to be used with the session-id
          callbacks so that while the session-ids are still stored in the
          cache, the decision to use them and how to look them up can be
          done by the callbacks.  The are the 'new', 'get' and 'remove'
          callbacks.  This can be used to determine the session-id
          to use depending on information like which port/host the connection
          is coming from.  Since the are also SSL_SESSION_set_app_data() and
          SSL_SESSION_get_app_data() functions, the application can hold
          information against the session-id as well.

03-Sep-97
        - Added lookup of CRLs to the by_dir method,
          X509_load_crl_file() also added.  Basically it means you can
          lookup CRLs via the same system used to lookup certificates.
        - Changed things so that the X509_NAME structure can contain
          ASN.1 BIT_STRINGS which is required for the unique
          identifier OID.
        - Fixed some problems with the auto flushing of the session-id
          cache.  It was not occuring on the server side.

02-Sep-97
        - Added SSL_CTX_sess_cache_size(SSL_CTX *ctx,unsigned long size)
          which is the maximum number of entries allowed in the
          session-id cache.  This is enforced with a simple FIFO list.
          The default size is 20*1024 entries which is rather large :-).
          The Timeout code is still always operating.

01-Sep-97
        - Added an argument to all the 'generate private key/prime`
          callbacks.  It is the last parameter so this should not
          break existing code but it is needed for C++.
        - Added the BIO_FLAGS_BASE64_NO_NL flag for the BIO_f_base64()
          BIO.  This lets the BIO read and write base64 encoded data
          without inserting or looking for '\n' characters.  The '-A'
          flag turns this on when using apps/enc.c.
        - RSA_NO_PADDING added to help BSAFE functionality.  This is a
          very dangerous thing to use, since RSA private key
          operations without random padding bytes (as PKCS#1 adds) can
          be attacked such that the private key can be revealed.
        - ASN.1 bug and rc2-40-cbc and rc4-40 added by
          Dr Stephen Henson <shenson@bigfoot.com>

31-Aug-97 (stuff added while I was away)        
        - Linux pthreads by Tim Hudson (tjh@cryptsoft.com).
        - RSA_flags() added allowing bypass of pub/priv match check
          in ssl/ssl_rsa.c - Tim Hudson.
        - A few minor bugs.

SSLeay 0.8.1 released.

19-Jul-97
        - Server side initated dynamic renegotiation is broken.  I will fix
          it when I get back from holidays.

15-Jul-97
        - Quite a few small changes.
        - INVALID_SOCKET usage cleanups from Alex Kiernan <alex@hisoft.co.uk>

09-Jul-97
        - Added 2 new values to the SSL info callback.
          SSL_CB_START which is passed when the SSL protocol is started
          and SSL_CB_DONE when it has finished sucsessfully.

08-Jul-97
        - Fixed a few bugs problems in apps/req.c and crypto/asn1/x_pkey.c
          that related to DSA public/private keys.
        - Added all the relevent PEM and normal IO functions to support
          reading and writing RSAPublic keys.
        - Changed makefiles to use ${AR} instead of 'ar r'

07-Jul-97
        - Error in ERR_remove_state() that would leave a dangling reference
          to a free()ed location - thanks to Alex Kiernan <alex@hisoft.co.uk>
        - s_client now prints the X509_NAMEs passed from the server
          when requesting a client cert.
        - Added a ssl->type, which is one of SSL_ST_CONNECT or
          SSL_ST_ACCEPT.  I had to add it so I could tell if I was
          a connect or an accept after the handshake had finished.
        - SSL_get_client_CA_list(SSL *s) now returns the CA names
          passed by the server if called by a client side SSL.

05-Jul-97
        - Bug in X509_NAME_get_text_by_OBJ(), looking starting at index
          0, not -1 :-(  Fix from Tim Hudson (tjh@cryptsoft.com).

04-Jul-97
        - Fixed some things in X509_NAME_add_entry(), thanks to
          Matthew Donald <matthew@world.net>.
        - I had a look at the cipher section and though that it was a
          bit confused, so I've changed it.
        - I was not setting up the RC4-64-MD5 cipher correctly.  It is
          a MS special that appears in exported MS Money.
        - Error in all my DH ciphers.  Section 7.6.7.3 of the SSLv3
          spec.  I was missing the two byte length header for the
          ClientDiffieHellmanPublic value.  This is a packet sent from
          the client to the server.  The SSL_OP_SSLEAY_080_CLIENT_DH_BUG
          option will enable SSLeay server side SSLv3 accept either
          the correct or my 080 packet format.
        - Fixed a few typos in crypto/pem.org.

02-Jul-97
        - Alias mapping for EVP_get_(digest|cipher)byname is now
          performed before a lookup for actual cipher.  This means
          that an alias can be used to 're-direct' a cipher or a
          digest.
        - ASN1_read_bio() had a bug that only showed up when using a
          memory BIO.  When EOF is reached in the memory BIO, it is
          reported as a -1 with BIO_should_retry() set to true.

01-Jul-97
        - Fixed an error in X509_verify_cert() caused by my
          miss-understanding how 'do { contine } while(0);' works.
          Thanks to Emil Sit <sit@mit.edu> for educating me :-)

30-Jun-97
        - Base64 decoding error.  If the last data line did not end with
          a '=', sometimes extra data would be returned.
        - Another 'cut and paste' bug in x509.c related to setting up the
          STDout BIO.

27-Jun-97
        - apps/ciphers.c was not printing due to an editing error.
        - Alex Kiernan <alex@hisoft.co.uk> send in a nice fix for
          a library build error in util/mk1mf.pl

26-Jun-97
        - Still did not have the auto 'experimental' code removal
          script correct.
        - A few header tweaks for Watcom 11.0 under Win32 from
          Rolf Lindemann <Lindemann@maz-hh.de>
        - 0 length OCTET_STRING bug in asn1_parse
        - A minor fix with an non-existent function in the MS .def files.
        - A few changes to the PKCS7 stuff.

25-Jun-97
        SSLeay 0.8.0 finally it gets released.

24-Jun-97
        Added a SSL_OP_EPHEMERAL_RSA option which causes all SSLv3 RSA keys to
        use a temporary RSA key.  This is experimental and needs some more work.
        Fixed a few Win16 build problems.

23-Jun-97
        SSLv3 bug. I was not doing the 'lookup' of the CERT structure
        correctly. I was taking the SSL->ctx->default_cert when I should
        have been using SSL->cert. The bug was in ssl/s3_srvr.c

20-Jun-97
        X509_ATTRIBUTES were being encoded wrongly by apps/reg.c and the
        rest of the library. Even though I had the code required to do
        it correctly, apps/req.c was doing the wrong thing.  I have fixed
        and tested everything.

        Missing a few #ifdef FIONBIO sections in crypto/bio/bss_acpt.c.

19-Jun-97
        Fixed a bug in the SSLv2 server side first packet handling. When
        using the non-blocking test BIO, the ssl->s2->first_packet flag
        was being reset when a would-block failure occurred when reading
        the first 5 bytes of the first packet. This caused the checking
        logic to run at the wrong time and cause an error.

        Fixed a problem with specifying cipher. If RC4-MD5 were used,
        only the SSLv3 version would be picked up.  Now this will pick
        up both SSLv2 and SSLv3 versions. This required changing the
        SSL_CIPHER->mask values so that they only mask the ciphers,
        digests, authentication, export type and key-exchange algorithms.

        I found that when a SSLv23 session is established, a reused
        session, of type SSLv3 was attempting to write the SSLv2 
        ciphers, which were invalid. The SSL_METHOD->put_cipher_by_char 
        method has been modified so it will only write out cipher which
        that method knows about.
