Ruby Crypt library is a pure-ruby implementation of a number of popular encryption algorithms. Block cyphers currently available include Blowfish, GOST, IDEA, and Rijndael (AES). Cypher Block Chaining (CBC) has been implemented. Twofish, Serpent, and CAST256 are planned for release soon.
Crypt is written entirely in ruby so deployment is simple - no platform concerns, no library dependencies, nothing to compile.
Performance is what you would expect from a pure-ruby implementation: it is adequate for shorter messages but I wouldn't try to encrypt my whole disk with it. If performance is critical then you might want to try ezcrypto's interface to OpenSSL.
What's New in This Release:
· This release is available as a Ruby gem for easy installation.
· A defect in Blowfish was fixed.
