Porting GNUPG

That sounds reasonable.  OK, the cryptlib random number code can be used in 
GnuPG under whatever terms are required (GPL I guess) on the understanding 
that it's not exclusively under the GPL, so I can keep using it and any 
updates to it as before (ie it's a dual license).  I hope that's what's 
required.

It's available via a link off my home page, 
http://www.cs.auckland.ac.nz/~pgut001/.  It contains a number of diagrams so 
it's done as a PDF file, at some point I'll get around to updating it and 
adding more info (the current version is 15 pages exactly, which was the limit
for papers at the conference).
