这是一个好用的MD5的C++类；这个类可以加在控制台 程序中也可用在MFC中， 并且提供了详细的错误处理 函数，是一个安全的类。例程是一个MD5的MFC程序， 支持字符串和文件两种输入-This is an easy to use the MD5 of the C++ category this category can be added to the console program can also be used in the MFC and to provide a detailed error handling function, is a type of security. MD5 is a routine procedure of MFC, and documentation to support two types of input string

PGP 是一种混合密码系统。当用户使用PGP 来对纯文字加密的时候， PGP 首先会压缩这 段纯文字。数据压缩能够节省调制解调器传输时间以及磁盘类空间，还有更重要的、强化密码法的 保密程度。-PGP is a hybrid cryptosystem. When the user to use PGP to encrypt the text, PGP will first this text compression. Data compression can save time and modem transmission disk space, and more importantly, to strengthen the password confidentiality law.
