A flexible aes instruction for a general purpose processor is provided that performs aes encryption or decryption using n rounds, where n includes the standard aes set of rounds {10, 12, 14}. A parameter is provided to allow the type of aes round to be selected, that is, whether it is a“last round”. In addition to standard aes, the flexible aes instruction allows an AES-like cipher with 20 rounds to be specified or a“one round”pass.
