It was written for a grad-level cryptology course. I thought this was more useful than my half-baked attempts at writing a cryptanalysis library, so here you go :) Given that this protocol has some performance advantages, I might implement a remote secure shell on top of it (after perhaps looking at some low-level optimizations to save some constant factors). SSH is kind of obsolete anyway. Parts of the program are based on Xavier Leroy's wonderful cryptokit, so I thank him in earnest. I think we should really go ahead and implement all sorts of cryptographic protocols in ocaml and release them under GPL. Description: This program implements a cryptographic network authentication scheme based on the work of Fiat-Shamir. The system is described in Section 6.8 of Network Security: Private Communication in a Public World by Kaufman et al.
