Message Digests

Message digests, or one-way hash functions, generate fixed-sized signatures from variable-sized texts, in such a way that it is computationally infeasible to determine the source text from the signature or to find a different text that hashes to the same signature. Hash functions in GNU Crypto are in the gnu.crypto.hash package, and are:
