  error if the cipher list is empty
- fix last commit in ssl_create_cipher_list
- clean up ssl_create_cipher_list

("perl util/ck_errf.pl */*.c */*/*.c" still reports many more.)

move some functions from exported header <openssl/dtl1.h> into "ssl_locl.h";
fix silly indentation (a TAB is *not* always 4 spaces)

compression identity is already present among the registered
compression methods, and if so, reject the addition request.

Declare SSL_COMP_get_compression_method() so it can be used properly.

Change ssltest.c so it checks what compression methods are available
and enumerates them.  As a side-effect, built-in compression methods
will be automagically loaded that way.  Additionally, change the
identities for ZLIB and RLE to be conformant to
draft-ietf-tls-compression-05.txt.

Finally, make update.

Next on my list: have the built-in compression methods added
"automatically" instead of requiring that the author call
SSL_COMP_add_compression_method() or
SSL_COMP_get_compression_methods().

ZLIB a known compression method, with the identity 1.

In ssl/s2_pkt.c, verify that the purported number of padding bytes is in
the legal range.

SSL according to RFC 2712.  His comment is:

This is a patch to openssl-SNAP-20010702 to support Kerberized SSL
authentication.  I'm expecting to have the full kssl-0.5 kit up on
sourceforge by the end of the week.  The full kit includes patches
for mod-ssl, apache, and a few text clients.  The sourceforge URL
is http://sourceforge.net/projects/kssl/ .

Thanks to a note from Simon Wilkinson I've replaced my KRB5 AP_REQ
message with a real KerberosWrapper struct.  I think this is fully
RFC 2712 compliant now, including support for the optional
authenticator field.  I also added openssl-style ASN.1 macros for
a few Kerberos structs; see crypto/krb5/ if you're interested.

Add EC vaporware: change relevant Makefiles and add some empty source
files.

"make update".

SSL/TLS session IDs in a server. According to RFC2246, the session ID is an
arbitrary value chosen by the server. It can be useful to have some control
over this "arbitrary value" so as to choose it in ways that can aid in
things like external session caching and balancing (eg. clustering). The
default session ID generation is to fill the ID with random data.

The callback used by default is built in to ssl_sess.c, but registering a
callback in an SSL_CTX or in a particular SSL overrides this. BTW: SSL
callbacks will override SSL_CTX callbacks, and a new SSL structure inherits
any callback set in its 'parent' SSL_CTX. The header comments describe how
this mechanism ticks, and source code comments describe (hopefully) why it
ticks the way it does.

Man pages are on the way ...

[NB: Lutz was also hacking away and helping me to figure out how best to do
this.]

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

Docs haven't been added at this stage. They are probably
best included in the 'ciphers' program docs.

same as RAND_seed() but takes an estimate of the entropy as an additional
argument.
