KEELOQ_ENcode　简单的加密程序，可惜就是没有源代码。-KEELOQ_ENcode simple encryption program, but is not the source code.

DES算法源代码，这是自己书写的源代码，里面采用了非常多的技巧来提高编解码的效率，研究算法和源码的朋友们，我书写的这个代码可以作为你们很好的参考。-DES algorithm source code, which is writing its own source code, which uses a lot of skills to improve the efficiency of the codec to study the algorithms and source of my friends, I am writing you this code can be used as a good reference.

是当今比较新的算法MD5，比DES和DES5都要加密好，是dll文件，在自己写的程序中加入它，就可以直接用了，全是意接口的形式-Is the relatively new algorithm MD5, should DES5 than DES and encryption, and is a dll file, written in their own process to join it, can be directly used, the interface is intended to form ~ ~ ~ ~

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
