Description
The Advanced Encryption Standard (AES) is a symmetric block cipher that was began development in 1997 to replace the Data Encryption Standard. It chosen as the U.S. federal government standard encryption algorithm in 2002. In 2003, it became the standard for classified information.
AES includes three block ciphers that identify the secret key lengths involved. In addition to the key lengths, these block ciphers differ with the number of rounds that plaintext is processed and transformed.
AES-128 | 128-bit key length | 10 rounds
AES-192 | 192-bit key length | 12 rounds
AES-256 | 256-bit key length | 14 rounds
