- SSLeay CHANGES
- ______________
-
-Changes between 0.8.x and 0.9.0b
-
-10-Apr-1998
-
-I said the next version would go out at easter, and so it shall.
-I expect a 0.9.1 will follow with portability fixes in the next few weeks.
-
-This is a quick, meet the deadline. Look to ssl-users for comments on what
-is new etc.
-
-eric (about to go bushwalking for the 4 day easter break :-)
-
-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 few 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.
-
-
- Changes between 0.8.0 and 0.8.1
-
- *) Mostly bug fixes.
- There is an Ephemeral DH cipher problem which is fixed.
-
- SSLeay 0.8.0
-
-This version of SSLeay has quite a lot of things different from the
-previous version.
-
-Basically check all callback parameters, I will be producing documentation
-about how to use things in th future. Currently I'm just getting 080 out
-the door. Please not that there are several ways to do everything, and
-most of the applications in the apps directory are hybrids, some using old
-methods and some using new methods.
-
-Have a look in demos/bio for some very simple programs and
-apps/s_client.c and apps/s_server.c for some more advanced versions.
-Notes are definitly needed but they are a week or so away.
-
-Anyway, some quick nots from Tim Hudson (tjh@cryptsoft.com)
----
-Quick porting notes for moving from SSLeay-0.6.x to SSLeay-0.8.x to
-get those people that want to move to using the new code base off to
-a quick start.
-
-Note that Eric has tidied up a lot of the areas of the API that were
-less than desirable and renamed quite a few things (as he had to break
-the API in lots of places anyrate). There are a whole pile of additional
-functions for making dealing with (and creating) certificates a lot
-cleaner.
-
-01-Jul-97
-Tim Hudson
-tjh@cryptsoft.com
-
----8<---
-
-To maintain code that uses both SSLeay-0.6.x and SSLeay-0.8.x you could
-use something like the following (assuming you #include "crypto.h" which
-is something that you really should be doing).
-
-#if SSLEAY_VERSION_NUMBER >= 0x0800
-#define SSLEAY8
-#endif
-
-buffer.h -> splits into buffer.h and bio.h so you need to include bio.h
- too if you are working with BIO internal stuff (as distinct
- from simply using the interface in an opaque manner)
-
-#include "bio.h" - required along with "buffer.h" if you write
- your own BIO routines as the buffer and bio
- stuff that was intermixed has been separated
- out
-
-envelope.h -> evp.h (which should have been done ages ago)
-
-Initialisation ... don't forget these or you end up with code that
-is missing the bits required to do useful things (like ciphers):
-
-SSLeay_add_ssl_algorithms()
-(probably also want SSL_load_error_strings() too but you should have
- already had that call in place)
-
-SSL_CTX_new() - requires an extra method parameter
- SSL_CTX_new(SSLv23_method())
- SSL_CTX_new(SSLv2_method())
- SSL_CTX_new(SSLv3_method())
-
- OR to only have the server or the client code
- SSL_CTX_new(SSLv23_server_method())
- SSL_CTX_new(SSLv2_server_method())
- SSL_CTX_new(SSLv3_server_method())
- or
- SSL_CTX_new(SSLv23_client_method())
- SSL_CTX_new(SSLv2_client_method())
- SSL_CTX_new(SSLv3_client_method())
-
-SSL_set_default_verify_paths() ... renamed to the more appropriate
-SSL_CTX_set_default_verify_paths()
-
-If you want to use client certificates then you have to add in a bit
-of extra stuff in that a SSLv3 server sends a list of those CAs that
-it will accept certificates from ... so you have to provide a list to
-SSLeay otherwise certain browsers will not send client certs.
-
-SSL_CTX_set_client_CA_list(ctx,SSL_load_client_CA_file(s_cert_file));
-
-
-X509_NAME_oneline(X) -> X509_NAME_oneline(X,NULL,0)
- or provide a buffer and size to copy the
- result into
-
-X509_add_cert -> X509_STORE_add_cert (and you might want to read the
- notes on X509_NAME structure changes too)
-
-
-VERIFICATION CODE
-=================
-
-The codes have all be renamed from VERIFY_ERR_* to X509_V_ERR_* to
-more accurately reflect things.
-
-The verification callback args are now packaged differently so that
-extra fields for verification can be added easily in future without
-having to break things by adding extra parameters each release :-)
-
-X509_cert_verify_error_string -> X509_verify_cert_error_string
-
-
-BIO INTERNALS
-=============
-
-Eric has fixed things so that extra flags can be introduced in
-the BIO layer in future without having to play with all the BIO
-modules by adding in some macros.
-
-The ugly stuff using
- b->flags ~= (BIO_FLAGS_RW|BIO_FLAGS_SHOULD_RETRY)
-becomes
- BIO_clear_retry_flags(b)
-
- b->flags |= (BIO_FLAGS_READ|BIO_FLAGS_SHOULD_RETRY)
-becomes
- BIO_set_retry_read(b)
-
-Also ... BIO_get_retry_flags(b), BIO_set_flags(b)
-
-
-
-OTHER THINGS
-============
-
-X509_NAME has been altered so that it isn't just a STACK ... the STACK
-is now in the "entries" field ... and there are a pile of nice functions
-for getting at the details in a much cleaner manner.
-
-SSL_CTX has been altered ... "cert" is no longer a direct member of this
-structure ... things are now down under "cert_store" (see x509_vfy.h) and
-things are no longer in a CERTIFICATE_CTX but instead in a X509_STORE.
-If your code "knows" about this level of detail then it will need some
-surgery.
-
-If you depending on the incorrect spelling of a number of the error codes
-then you will have to change your code as these have been fixed.
-
-ENV_CIPHER "type" got renamed to "nid" and as that is what it actually
-has been all along so this makes things clearer.
-ify_cert_error_string(ctx->error));
-
-SSL_R_NO_CIPHER_WE_TRUST -> SSL_R_NO_CIPHER_LIST
- and SSL_R_REUSE_CIPHER_LIST_NOT_ZERO
-
-
-
- Changes between 0.7.x and 0.8.0
-
- *) There have been lots of changes, mostly the addition of SSLv3.
- There have been many additions from people and amongst
- others, C2Net has assisted greatly.
-
- Changes between 0.7.x and 0.7.x
-
- *) Internal development version only
-
-SSLeay 0.6.6 13-Jan-1997
-
-The main additions are
-
-- assember for x86 DES improvments.
- From 191,000 per second on a pentium 100, I now get 281,000. The inner
- loop and the IP/FP modifications are from
- Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk>. Many thanks for his
- contribution.
-- The 'DES macros' introduced in 0.6.5 now have 3 types.
- DES_PTR1, DES_PTR2 and 'normal'. As per before, des_opts reports which
- is best and there is a summery of mine in crypto/des/options.txt
-- A few bug fixes.
-- Added blowfish. It is not used by SSL but all the other stuff that
- deals with ciphers can use it in either ecb, cbc, cfb64 or ofb64 modes.
- There are 3 options for optimising Blowfish. BF_PTR, BF_PTR2 and 'normal'.
- BF_PTR2 is pentium/x86 specific. The correct option is setup in
- the 'Configure' script.
-- There is now a 'get client certificate' callback which can be
- 'non-blocking'. If more details are required, let me know. It will
- documented more in SSLv3 when I finish it.
-- Bug fixes from 0.6.5 including the infamous 'ca' bug. The 'make test'
- now tests the ca program.
-- Lots of little things modified and tweaked.
-
- SSLeay 0.6.5
-
-After quite some time (3 months), the new release. I have been very busy
-for the last few months and so this is mostly bug fixes and improvments.
-
-The main additions are
-
-- assember for x86 DES. For all those gcc based systems, this is a big
- improvement. From 117,000 DES operation a second on a pentium 100,
- I now get 191,000. I have also reworked the C version so it
- now gives 148,000 DESs per second.
-- As mentioned above, the inner DES macros now have some more variant that
- sometimes help, sometimes hinder performance. There are now 3 options
- DES_PTR (ptr vs array lookup), DES_UNROLL (full vs partial loop unrolling)
- and DES_RISC (a more register intensive version of the inner macro).
- The crypto/des/des_opts.c program, when compiled and run, will give
- an indication of the correct options to use.
-- The BIO stuff has been improved. Read doc/bio.doc. There are now
- modules for encryption and base64 encoding and a BIO_printf() function.
-- The CA program will accept simple one line X509v3 extensions in the
- ssleay.cnf file. Have a look at the example. Currently this just
- puts the text into the certificate as an OCTET_STRING so currently
- the more advanced X509v3 data types are not handled but this is enough
- for the netscape extensions.
-- There is the start of a nicer higher level interface to the X509
- strucutre.
-- Quite a lot of bug fixes.
-- CRYPTO_malloc_init() (or CRYPTO_set_mem_functions()) can be used
- to define the malloc(), free() and realloc() routines to use
- (look in crypto/crypto.h). This is mostly needed for Windows NT/95 when
- using DLLs and mixing CRT libraries.
-
-In general, read the 'VERSION' file for changes and be aware that some of
-the new stuff may not have been tested quite enough yet, so don't just plonk
-in SSLeay 0.6.5 when 0.6.4 used to work and expect nothing to break.
-
-SSLeay 0.6.4 30/08/96 eay
-
-I've just finished some test builds on Windows NT, Windows 3.1, Solaris 2.3,
-Solaris 2.5, Linux, IRIX, HPUX 10 and everthing seems to work :-).
-
-The main changes in this release
-
-- Thread safe. have a read of doc/threads.doc and play in the mt directory.
- For anyone using 0.6.3 with threads, I found 2 major errors so consider
- moving to 0.6.4. I have a test program that builds under NT and
- solaris.
-- The get session-id callback has changed. Have a read of doc/callback.doc.
-- The X509_cert_verify callback (the SSL_verify callback) now
- has another argument. Have a read of doc/callback.doc
-- 'ca -preserve', sign without re-ordering the DN. Not tested much.
-- VMS support.
-- Compile time memory leak detection can now be built into SSLeay.
- Read doc/memory.doc
-- CONF routines now understand '\', '\n', '\r' etc. What this means is that
- the SPKAC object mentioned in doc/ns-ca.doc can be on multiple lines.
-- 'ssleay ciphers' added, lists the default cipher list for SSLeay.
-- RC2 key setup is now compatable with Netscape.
-- Modifed server side of SSL implementation, big performance difference when
- using session-id reuse.
-
-0.6.3
-
-Bug fixes and the addition of some nice stuff to the 'ca' program.
-Have a read of doc/ns-ca.doc for how hit has been modified so
-it can be driven from a CGI script. The CGI script is not provided,
-but that is just being left as an excersize for the reader :-).
-
-0.6.2
-
-This is most bug fixes and functionality improvements.
-
-Additions are
-- More thread debugging patches, the thread stuff is still being
- tested, but for those keep to play with stuff, have a look in
- crypto/cryptlib.c. The application needs to define 1 (or optionaly
- a second) callback that is used to implement locking. Compiling
- with LOCK_DEBUG spits out lots of locking crud :-).
- This is what I'm currently working on.
-- SSL_CTX_set_default_passwd_cb() can be used to define the callback
- function used in the SSL*_file() functions used to load keys. I was
- always of the opinion that people should call
- PEM_read_RSAPrivateKey() and pass the callback they want to use, but
- it appears they just want to use the SSL_*_file() function() :-(.
-- 'enc' now has a -kfile so a key can be read from a file. This is
- mostly used so that the passwd does not appear when using 'ps',
- which appears imposible to stop under solaris.
-- X509v3 certificates now work correctly. I even have more examples
- in my tests :-). There is now a X509_EXTENSION type that is used in
- X509v3 certificates and CRLv2.
-- Fixed that signature type error :-(
-- Fixed quite a few potential memory leaks and problems when reusing
- X509, CRL and REQ structures.
-- EVP_set_pw_prompt() now sets the library wide default password
- prompt.
-- The 'pkcs7' command will now, given the -print_certs flag, output in
- pem format, all certificates and CRL contained within. This is more
- of a pre-emtive thing for the new verisign distribution method. I
- should also note, that this also gives and example in code, of how
- to do this :-), or for that matter, what is involved in going the
- other way (list of certs and crl -> pkcs7).
-- Added RSA's DESX to the DES library. It is also available via the
- EVP_desx_cbc() method and via 'enc desx'.
-
-SSLeay 0.6.1
-
-The main functional changes since 0.6.0 are as follows
-- Bad news, the Microsoft 060 DLL's are not compatable, but the good news is
- that from now on, I'll keep the .def numbers the same so they will be.
-- RSA private key operations are about 2 times faster that 0.6.0
-- The SSL_CTX now has more fields so default values can be put against
- it. When an SSL structure is created, these default values are used
- but can be overwritten. There are defaults for cipher, certificate,
- private key, verify mode and callback. This means SSL session
- creation can now be
- ssl=SSL_new()
- SSL_set_fd(ssl,sock);
- SSL_accept(ssl)
- ....
- All the other uglyness with having to keep a global copy of the
- private key and certificate/verify mode in the server is now gone.
-- ssl/ssltest.c - one process talking SSL to its self for testing.
-- Storage of Session-id's can be controled via a session_cache_mode
- flag. There is also now an automatic default flushing of
- old session-id's.
-- The X509_cert_verify() function now has another parameter, this
- should not effect most people but it now means that the reason for
- the failure to verify is now available via SSL_get_verify_result(ssl).
- You don't have to use a global variable.
-- SSL_get_app_data() and SSL_set_app_data() can be used to keep some
- application data against the SSL structure. It is upto the application
- to free the data. I don't use it, but it is available.
-- SSL_CTX_set_cert_verify_callback() can be used to specify a
- verify callback function that completly replaces my certificate
- verification code. Xcert should be able to use this :-).
- The callback is of the form int app_verify_callback(arg,ssl,cert).
- This needs to be documented more.
-- I have started playing with shared library builds, have a look in
- the shlib directory. It is very simple. If you need a numbered
- list of functions, have a look at misc/crypto.num and misc/ssl.num.
-- There is some stuff to do locking to make the library thread safe.
- I have only started this stuff and have not finished. If anyone is
- keen to do so, please send me the patches when finished.
-
-So I have finally made most of the additions to the SSL interface that
-I thought were needed.
-
-There will probably be a pause before I make any non-bug/documentation
-related changes to SSLeay since I'm feeling like a bit of a break.
-
-eric - 12 Jul 1996
-I saw recently a comment by some-one that we now seem to be entering
-the age of perpetual Beta software.
-Pioneered by packages like linux but refined to an art form by
-netscape.
-
-I too wish to join this trend with the anouncement of SSLeay 0.6.0 :-).
-
-There are quite a large number of sections that are 'works in
-progress' in this package. I will also list the major changes and
-what files you should read.
-
-BIO - this is the new IO structure being used everywhere in SSLeay. I
-started out developing this because of microsoft, I wanted a mechanism
-to callback to the application for all IO, so Windows 3.1 DLL
-perversion could be hidden from me and the 15 different ways to write
-to a file under NT would also not be dictated by me at library build
-time. What the 'package' is is an API for a data structure containing
-functions. IO interfaces can be written to conform to the
-specification. This in not intended to hide the underlying data type
-from the application, but to hide it from SSLeay :-).
-I have only really finished testing the FILE * and socket/fd modules.
-There are also 'filter' BIO's. Currently I have only implemented
-message digests, and it is in use in the dgst application. This
-functionality will allow base64/encrypto/buffering modules to be
-'push' into a BIO without it affecting the semantics. I'm also
-working on an SSL BIO which will hide the SSL_accept()/SLL_connet()
-from an event loop which uses the interface.
-It is also possible to 'attach' callbacks to a BIO so they get called
-before and after each operation, alowing extensive debug output
-to be generated (try running dgst with -d).
-
-Unfortunaly in the conversion from 0.5.x to 0.6.0, quite a few
-functions that used to take FILE *, now take BIO *.
-The wrappers are easy to write
-
-function_fp(fp,x)
-FILE *fp;
- {
- BIO *b;
- int ret;
-
- if ((b=BIO_new(BIO_s_file())) == NULL) error.....
- BIO_set_fp(b,fp,BIO_NOCLOSE);
- ret=function_bio(b,x);
- BIO_free(b);
- return(ret);
- }
-Remember, there are no functions that take FILE * in SSLeay when
-compiled for Windows 3.1 DLL's.
-
---
-I have added a general EVP_PKEY type that can hold a public/private
-key. This is now what is used by the EVP_ functions and is passed
-around internally. I still have not done the PKCS#8 stuff, but
-X509_PKEY is defined and waiting :-)
-
---
-For a full function name listings, have a look at ms/crypt32.def and
-ms/ssl32.def. These are auto-generated but are complete.
-Things like ASN1_INTEGER_get() have been added and are in here if you
-look. I have renamed a few things, again, have a look through the
-function list and you will probably find what you are after. I intend
-to at least put a one line descrition for each one.....
-
---
-Microsoft - thats what this release is about, read the MICROSOFT file.
-
---
-Multi-threading support. I have started hunting through the code and
-flaging where things need to be done. In a state of work but high on
-the list.
-
---
-For random numbers, edit e_os.h and set DEVRANDOM (it's near the top)
-be be you random data device, otherwise 'RFILE' in e_os.h
-will be used, in your home directory. It will be updated
-periodically. The environment variable RANDFILE will override this
-choice and read/write to that file instead. DEVRANDOM is used in
-conjunction to the RFILE/RANDFILE. If you wish to 'seed' the random
-number generator, pick on one of these files.
-
---
-
-The list of things to read and do
-
-dgst -d
-s_client -state (this uses a callback placed in the SSL state loop and
- will be used else-where to help debug/monitor what
- is happening.)
-
-doc/why.doc
-doc/bio.doc <- hmmm, needs lots of work.
-doc/bss_file.doc <- one that is working :-)
-doc/session.doc <- it has changed
-doc/speed.doc
- also play with ssleay version -a. I have now added a SSLeay()
- function that returns a version number, eg 0600 for this release
- which is primarily to be used to check DLL version against the
- application.
-util/* Quite a few will not interest people, but some may, like
- mk1mf.pl, mkdef.pl,
-util/do_ms.sh
-
-try
-cc -Iinclude -Icrypto -c crypto/crypto.c
-cc -Iinclude -Issl -c ssl/ssl.c
-You have just built the SSLeay libraries as 2 object files :-)
-
-Have a general rummage around in the bin stall directory and look at
-what is in there, like CA.sh and c_rehash
-
-There are lots more things but it is 12:30am on a Friday night and I'm
-heading home :-).
-
-eric 22-Jun-1996
-This version has quite a few major bug fixes and improvements. It DOES NOT
-do SSLv3 yet.
-
-The main things changed
-- A Few days ago I added the s_mult application to ssleay which is
- a demo of an SSL server running in an event loop type thing.
- It supports non-blocking IO, I have finally gotten it right, SSL_accept()
- can operate in non-blocking IO mode, look at the code to see how :-).
- Have a read of doc/s_mult as well. This program leaks memory and
- file descriptors everywhere but I have not cleaned it up yet.
- This is a demo of how to do non-blocking IO.
-- The SSL session management has been 'worked over' and there is now
- quite an expansive set of functions to manipulate them. Have a read of
- doc/session.doc for some-things I quickly whipped up about how it now works.
- This assume you know the SSLv2 protocol :-)
-- I can now read/write the netscape certificate format, use the
- -inform/-outform 'net' options to the x509 command. I have not put support
- for this type in the other demo programs, but it would be easy to add.
-- asn1parse and 'enc' have been modified so that when reading base64
- encoded files (pem format), they do not require '-----BEGIN' header lines.
- The 'enc' program had a buffering bug fixed, it can be used as a general
- base64 -> binary -> base64 filter by doing 'enc -a -e' and 'enc -a -d'
- respecivly. Leaving out the '-a' flag in this case makes the 'enc' command
- into a form of 'cat'.
-- The 'x509' and 'req' programs have been fixed and modified a little so
- that they generate self-signed certificates correctly. The test
- script actually generates a 'CA' certificate and then 'signs' a
- 'user' certificate. Have a look at this shell script (test/sstest)
- to see how things work, it tests most possible combinations of what can
- be done.
-- The 'SSL_set_pref_cipher()' function has been 'fixed' and the prefered name
- of SSL_set_cipher_list() is now the correct API (stops confusion :-).
- If this function is used in the client, only the specified ciphers can
- be used, with preference given to the order the ciphers were listed.
- For the server, if this is used, only the specified ciphers will be used
- to accept connections. If this 'option' is not used, a default set of
- ciphers will be used. The SSL_CTX_set_cipher_list(SSL_CTX *ctx) sets this
- list for all ciphers started against the SSL_CTX. So the order is
- SSL cipher_list, if not present, SSL_CTX cipher list, if not
- present, then the library default.
- What this means is that normally ciphers like
- NULL-MD5 will never be used. The only way this cipher can be used
- for both ends to specify to use it.
- To enable or disable ciphers in the library at build time, modify the
- first field for the cipher in the ssl_ciphers array in ssl/ssl_lib.c.
- This file also contains the 'pref_cipher' list which is the default
- cipher preference order.
-- I'm not currently sure if the 'rsa -inform net' and the 'rsa -outform net'
- options work. They should, and they enable loading and writing the
- netscape rsa private key format. I will be re-working this section of
- SSLeay for the next version. What is currently in place is a quick and
- dirty hack.
-- I've re-written parts of the bignum library. This gives speedups
- for all platforms. I now provide assembler for use under Windows NT.
- I have not tested the Windows 3.1 assembler but it is quite simple code.
- This gives RSAprivate_key operation encryption times of 0.047s (512bit key)
- and 0.230s (1024bit key) on a pentium 100 which I consider reasonable.
- Basically the times available under linux/solaris x86 can be achieve under
- Windows NT. I still don't know how these times compare to RSA's BSAFE
- library but I have been emailing with people and with their help, I should
- be able to get my library's quite a bit faster still (more algorithm changes).
- The object file crypto/bn/asm/x86-32.obj should be used when linking
- under NT.
-- 'make makefile.one' in the top directory will generate a single makefile
- called 'makefile.one' This makefile contains no perl references and
- will build the SSLeay library into the 'tmp' and 'out' directories.
- util/mk1mf.pl >makefile.one is how this makefile is
- generated. The mk1mf.pl command take several option to generate the
- makefile for use with cc, gcc, Visual C++ and Borland C++. This is
- still under development. I have only build .lib's for NT and MSDOS
- I will be working on this more. I still need to play with the
- correct compiler setups for these compilers and add some more stuff but
- basically if you just want to compile the library
- on a 'non-unix' platform, this is a very very good file to start with :-).
- Have a look in the 'microsoft' directory for my current makefiles.
- I have not yet modified things to link with sockets under Windows NT.
- You guys should be able to do this since this is actually outside of the
- SSLeay scope :-). I will be doing it for myself soon.
- util/mk1mf.pl takes quite a few options including no-rc, rsaref and no-sock
- to build without RC2/RC4, to require RSAref for linking, and to
- build with no socket code.
-
-- Oh yes, the cipher that was reported to be compatible with RSA's RC2 cipher
- that was posted to sci.crypt has been added to the library and SSL.
- I take the view that if RC2 is going to be included in a standard,
- I'll include the cipher to make my package complete.
- There are NO_RC2, NO_RC4 and NO_IDEA macros to remove these ciphers
- at compile time. I have not tested this recently but it should all work
- and if you are in the USA and don't want RSA threatening to sue you,
- you could probably remove the RC4/RC2 code inside these sections.
- I may in the future include a perl script that does this code
- removal automatically for those in the USA :-).
-- I have removed all references to sed in the makefiles. So basically,
- the development environment requires perl and sh. The build environment
- does not (use the makefile.one makefile).
- The Configure script still requires perl, this will probably stay that way
- since I have perl for Windows NT :-).

-PS Have a look in the VERSION file for more details on the changes and
- bug fixes.
-I have fixed a few bugs, added alpha and x86 assembler and generally cleaned
-things up. This version will be quite stable, mostly because I'm on
-holidays until 10-March-1996. For any problems in the interum, send email
-to Tim Hudson <tjh@mincom.oz.au>.
-
-SSLeay 0.5.0
-
-12-12-95
-This is going out before it should really be released.
-
-I leave for 11 weeks holidays on the 22-12-95 and so I either sit on
-this for 11 weeks or get things out. It is still going to change a
-lot in the next week so if you do grab this version, please test and
-give me feed back ASAP, inculuding questions on how to do things with
-the library. This will prompt me to write documentation so I don't
-have to answer the same question again :-).
-
-This 'pre' release version is for people who are interested in the
-library. The applications will have to be changed to use
-the new version of the SSL interface. I intend to finish more
-documentation before I leave but until then, look at the programs in
-the apps directory. As far as code goes, it is much much nicer than
-the old version.
-
-The current library works, has no memory leaks (as far as I can tell)
-and is far more bug free that 0.4.5d. There are no global variable of
-consequence (I believe) and I will produce some documentation that
-tell where to look for those people that do want to do multi-threaded
-stuff.
-
-There should be more documentation. Have a look in the
-doc directory. I'll be adding more before I leave, it is a start
-by mostly documents the crypto library. Tim Hudson will update
-the web page ASAP. The spelling and grammar are crap but
-it is better than nothing :-)
-
-Reasons to start playing with version 0.5.0
-- All the programs in the apps directory build into one ssleay binary.
-- There is a new version of the 'req' program that generates certificate
- requests, there is even documentation for this one :-)
-- There is a demo certification authorithy program. Currently it will
- look at the simple database and update it. It will generate CRL from
- the data base. You need to edit the database by hand to revoke a
- certificate, it is my aim to use perl5/Tk but I don't have time to do
- this right now. It will generate the certificates but the management
- scripts still need to be written. This is not a hard task.
-- Things have been cleaned up alot.
-- Have a look at the enc and dgst programs in the apps directory.
-- It supports v3 of x509 certiticates.
-
-
-Major things missing.
-- I have been working on (and thinging about) the distributed x509
- hierachy problem. I have not had time to put my solution in place.
- It will have to wait until I come back.
-- I have not put in CRL checking in the certificate verification but
- it would not be hard to do. I was waiting until I could generate my
- own CRL (which has only been in the last week) and I don't have time
- to put it in correctly.
-- Montgomery multiplication need to be implemented. I know the
- algorithm, just ran out of time.
-- PKCS#7. I can load and write the DER version. I need to re-work
- things to support BER (if that means nothing, read the ASN1 spec :-).
-- Testing of the higher level digital envelope routines. I have not
- played with the *_seal() and *_open() type functions. They are
- written but need testing. The *_sign() and *_verify() functions are
- rock solid.
-- PEM. Doing this and PKCS#7 have been dependant on the distributed
- x509 heirachy problem. I started implementing my ideas, got
- distracted writing a CA program and then ran out of time. I provide
- the functionality of RSAref at least.
-- Re work the asm. code for the x86. I've changed by low level bignum
- interface again, so I really need to tweak the x86 stuff. gcc is
- good enough for the other boxes.
