这个是MD5算法C的源代码，希望对大家有用

DES密码体制的安全性应该不依赖于算法的保密，其安全性仅以加密密钥的保密为基础-DES password security system should not depend on secrecy algorithm, the only security encryption key based on the confidentiality

pki资料，是希望入门pki的人的最好的参考资料-pki data entry pki is the best reference.

RSA算法的实现，大家可以参考看看,用C实现-RSA algorithm, we can reference to see, using C to achieve

md5的加密函数 iis下运行； 用法: 1：页面包含该文件 2：调用方法MD5(sMessage,stype) 例dim md_=md5("admin"，32) *注：最高32位。-md5 encryption function running under iis Usage: 1: page 2 of the document contains: call method MD5 (sMessage, stype) were dim md_ = md5 ( " admin" , 32)* Note: maximum 32.
