Cryptage blowfish
WebFor the AES competition, NIST required that candidates use 128-bit blocks, for precisely that reason. Twofish is a 128-bit block cipher, designed by the same Bruce Schneier than Blowfish, and is claimed to be "related" to Blowfish, although the lineage is not totally obvious when you look at the algorithms.
