这个是高级加密标准的C语言程序-this is the Advanced Encryption Standard C Programming Language

AES算法主要包括三个方面：轮变化、轮数和密钥扩展。本文以128为例，介绍算法的基本原理；结合C语言，实现高级数据加密算法AES（AES-128）。-AES algorithm mainly includes three aspects: round of changes, round number and key expansion. In this paper, 128 for example, introduce the basic principles of algorithm combination of C language, the realization of advanced data encryption algorithm AES (AES-128).

ECC Implmentation . The programme works without any problem on compiler Dev C++ available at bloodshed.

绝好的文件分割器.-excellent paper dividers.

这是我用c++实现的一个DES加密算法！应该可以适合那些对加密感兴趣的人看。-This is achieved with c a DES encryption algorithm. Should be suitable for those interested in encryption right people.

用VB实现的DES加密算法，适合于小型VPN的明文加密传输-the DES encryption algorithm, suited to the small expressly VPN encryption transmission

精简后的md5，hmac―md5 算法，方面程序调用

用来替换动态链接库的相互引用关系，去掉强签名请求。

MD5算法的ASP实现． 它在MD4的基础上增加了"安全-带子"（Safety-Belts）的概念。虽然MD5比MD4稍微慢一些，但却更为安全。MD5也为一种非常优秀的中间技术。-MD5 algorithm ASP. It MD4 increase on the basis of "safety-belt" (Safety-Belts) concept. Although MD5 than MD4 slightly slower, but more secure. MD5 also as a very good intermediate technology.
