An implementation of the Twofish Symmetric-key cipher.
Implements the Twofish symmetric block cipher, designed by: Bruce Schneier, John Kelsey, Doug Whiting, David Wagner, Chris Hall, and Niels Ferguson.
As well, this module includes some generic definitions for ciphers and cipher-block-chaining mode in the Data.Cipher module. In the future, these should probably either be moved to their own package, or all of this should be merged into the Crypto package.
Acknowledgments:
Dominic Steinitz, Caylee Hogg and Thomas DuBuisson for their work on the Crypto package, upon which this package depends.
Stephen Tetley for his advice and code examples provided on the Haskell-Beginners mailing list in response to a question I had, which helped me to create a transformer version of the Cbc monad. (now deprecated in favor of the CBC definitions in crypto-api)
