   If you are trying to secure the network, and if you can trust the
   machines that you are trying to secure, then I suggest you look into
   Kerberos (comp.protocols.kerberos, or kerberos@mit.edu).  It is based
   on DES, and uses shared secrets between entities to prove
   authenticity.

   It doesn't sound like you need real-time key distribution, which is
   something that Public Key algorithms have over secret-key algorithms,
   but if you have physical access to both machines, then you can place a
   shared secret on both machines and now that link is secure...

   I hope this helps.  If you have any more questions, feel free to ask.

My fiquestion is: how do I get kerberos source code, with all the DES
code and hooks in place?  Does your answer vary, depending on whether
I'm in the US or the UK?
