C++编写的MD5加密算法校验并计算的一个实例，DOS提示窗模式，主要功能实现了字符串摘要、文件摘要功能。

　　Md5.cpp是算法的核心代码，来自rfc-1321 ；Main.cpp是主窗口程序。在命令提示符窗口中输入你要进行MD5运算的字符串，程序会计算出对应的MD5加密字串。-C++ to prepare the MD5 checksum encryption algorithm and an example of the calculation, DOS prompt window mode, the main functions of a string summary document containing a summary of features. Md5.cpp is the core algorithm code from the rfc-1321　Main.cpp procedures is the main window. At the command prompt window to enter your MD5 string operations, the program calculates the corresponding MD5 encrypted string.
