• A specification for the encryption of electronic data established in 2001 by the U.S. National Institute of Standards and Technology (NIST). AES is a subset of the Rijndael block cipher developed by Vincent Rijmen and Joan Daemen. For AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths: 128, 192, and 256 bits, to make AES-128, AES-192, and AES-256, respectively. ← Wikipedia
