CRYPTON   is a block cipher designed by a Korean team as a candidate for the AES competition; it did not make it into the finals. Like all AES candidates, it uses 128-bit blocks and supports key sizes of 128, 192 or 256 bits.
CRYPTON uses a SP network with 12 rounds, does byte-level substitutions, and for some operations treats the 128-bit text as a four-by-four array of bytes. Overall, the design is rather similar to AES though some of the operations are different.
