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。 LPCSTR TargetFile(char *filename=NULL) //计算文件的MD5值 void TargetStr(LPCSTR str) //计算字符串的MD5值 LPCSTR GetDigestKey() //取MD5运算后的结果 LPCSTR GetErr() //如果有错误，取错误字串-This a user-friendly MD5 C; This category can be added to the Console program is available in MFC, and provided a detailed error handling function, is a safety class. MD5 is a routine MFC procedures, and documentation to support a string of two input. LPCSTR TargetFile (char* filename = NULL)// calculate MD5 value of the document void TargetStr (LPCSTR str)// calculate MD5 string value LPCSTR GetDigestKey ()// Operational MD5 from the results LPCSTR GetErr ()// If there were mistakes from the wrong string
