The cryptography package provides some basic cryptographic algorithms andprotocols. This change set integrates algorithms implemented by several membersof the Squeak community, including Leandro Caniglia, John Maloney,Duane Maxwell, Luciano Notarfrancesco and Carlos Sarraute. There isn't muchdocumentation, but browsing the tests (CryptoTest) will give you a pretty goodidea of how to use it.This package includes:- Symmetric key algorithms: DES, 3DES, AES (Rijndael), ARC4- Block cipher modes: CBC, CFB, OFB- Hash functions: MD4, MD5, SHA1- Public key algorithms: DSA, ElGamal, RSA- Other stuff: HMACs, Diffie-Hellman, a random pool, a secure prng, a primes finder
