DES加密算法及详细说明（HTM）

The Advanced Encryption Standard (AES) specifies a FIPS- approved cryptographic algorithm that can be used to protect electronic data.  The AES-128 pipelined cipher module uses AES algorithm which is a symmetric block cipher to encrypt (encipher) information. This module is optimized for speed as it pipeline hardware to perform repeated sequence called round
