When libdes was replaced with OpenSSL's libcrypto, there were a few
interfaces that the former implemented but the latter did not. Because
some software in the base system still depended upon these interfaces,
we simply included them in our libcrypto (rnd_keys.c).
Now, finally get around to removing the dependencies on these
interfaces. There were basically two cases:
des_new_random_key -- This is just a wrapper for des_random_key, and
these calls were replaced.
des_init_random_number_generator et. al. -- A few functions were used
by the application to seed libdes's PRNG. These are not necessary
when using libcrypto, as OpenSSL internally seeds the PRNG from
/dev/random. These calls were simply removed.
Again, some of the Kerberos 4 files have been taken off the vendor
branch. I do not expect there to be future imports of KTH Kerberos 4.

1) ANSIfy.
2) Clean up ifdefs so that
a) ones that never/always apply are appropriately either
fully removed, or just the #if junk is removed.
b) change #if defined(FOO) for appropiate values of FOO.
(currently AUTHENTICATION and ENCRYPTION)
3) WARNS=2 fixing
4) GC other unused stuff
This code can now be unifdef(1)ed to make non-crypto telnet.

This is by the kind permission of Dave Safford, formerly of TAMU who wrote the
original code. Here is an excerpt of the e-mail exchange concerning this
issue:

This is the standard BSD license with clause 3 removed and clause 4
suitably renumbered.

I just mistakenly commited this to RELENG_4. I have contacted Jordan to see
about how to fix this. Pass the pointy hat.

SRA does a Diffie-Hellmen exchange and then DES-encrypts the
authentication data. If the authentication is successful, it also
sets up a session key for DES encryption.
SRA was originally developed at Texas A&M University.
This code is probably export restricted (despite the fact that I
originally found it at a University in Germany).
SRA is not perfect. It is vulnerable to monkey-in-the-middle attacks
and does not use tremendously large DH constants (and thus an individual
exchange probably could be factored in a few days on modern CPU
horsepower). It does not, however, require any changes in user or
administrative behavior and foils session hijacking and sniffing.
The goal of this commit is that telnet and telnetd end up in the DES
distribution and that therefore an encrypted session telnet becomes
standard issue for FreeBSD.

telnet, and after userland diffs have been merged in, will be used to
build the non-kerberised sources as well. (See unifdef(1) for details)
