GClasses::GCrypto Class Reference

This is a symmetric-key block-cypher. It utilizes a 2048-byte internal state which is initialized using the passphrase. It uses repeated applications of sha-512 to advance the internal state, and to generate an 1024-byte pad that it xor's with your data to encrypt or decrypt it. Warning: You use this algorithm at your own risk. Many encryption algorithms eventually turn out to be insecure, and to my knowledge, this algorithm has not yet been extensively scrutinized. More...
