NAME: CAST-128
CREATOR: Entrust Technologies
PB AUTHOR: Greg Turgeon
DESCRIPTION: A DES-like Substitution-Permutation Network (SPN) cryptosystem which appears to have good resistance to differential cryptanalysis, linear cryptanalysis, and related-key cryptanalysis. This cipher also possesses a number of other desirable cryptographic properties, including avalanche, Strict Avalanche Criterion (SAC), Bit Independence Criterion (BIC), no complementation property, and an absence of weak and semi-weak keys. It thus appears to be a good candidate for general-purpose use throughout the Internet community wherever a cryptographically-strong, freely-available encryption algorithm is required.
NOTES: For further info see RFC 2144. This sample source is compatible with PBWIN7 and uses macros.
