Catacomb

Catacomb is a cryptographic library. It covers quite a lot of

of scope for improvement, implementing more block ciphers and
hash functions for example. It contains a relatively extensive
multiprecision arithmetic library suitable for implementing a

Once your adversary has acquired a few signed messages, which
shouldn't be too hard, he can recover either your entire key, or
management for public-key systems. This needs a lot of
thought, however.

* Arithmetic in finite fields other than the prime-order
fields constructed by integer multiplication with a prime
modulus. Interesting variants of Diffie-Hellman and other
people have suggestions then I'll consider them fairly, although
they shouldn't conflict with my main objectives.
