I posted C code for CAST to sci.crypt a few months ago, you should be able to
get it using DejaNews. I'll have the C version and a fast asm implementation
in the next release of cryptlib,
http://www.cs.auckland.ac.nz/~pgut001/cryptlib.html. It's free for anyone to
use, and originates from outside the US. It's a very nice algorithm, there's
a paper on the Nortel site giving the full design details.
