Keccak (pronounced [kɛtʃak], like “ketchak”) is a cryptographic hash function designed by Guido Bertoni, Joan Daemen, Michaël Peeters and Gilles Van Assche. Keccak is one of five finalists in the NIST hash function competition to select a SHA-3 algorithm. The authors claim 12.5 cycles per byte on an Intel Core 2 CPU. It is notably faster than all other finalists in hardware implementations.
