一个简单的数字签名算法的实现，能进行简单的文件签名和传送...

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

取主机网卡地址，可用于加密-from mainframe NIC addresses can be used to encrypt

一款和不错的用VC实现的DES算法,希望对大家对提意见,-section and a good VC with the DES algorithm, we hope that the right to say,

MD5 加密算法 Delphi 源码。 编译为dll文件，方便其他语言的系统调用-MD5 encryption algorithm Delphi source. Dll file to compile and facilitate language system calls

这是用C编写的文件合并与分割的源代码，还请各位指教。-This is the document prepared by C combined with the partition of the source code, also called upon to advise.
