简单的文件加密代码 一个不错的文件加密系统，对你工作的安全大大加强。-simple file encryption code a good file encryption system, you have the right security greatly enhanced.

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
