奇迹C1 C2 C3 C4协议加密与解密(MU C1 C2 C3 C4 encrypt and decrypt)

主流的32位MD5加密算法在.NET2003平台上的实现（WINFORM模式）例子，如果你希望给自己的项目加入安全机制但却对MD5加密未曾接触，那可能这个例子可以给你一点帮助(mainstream 32 MD5 encryption algorithm.NET2003 platform achievement (WINFORM mode) example, if you want to own the item by adding security mechanisms but right MD5 encryption has not been exposed to, That may be the case can give you a little help)

MD5算法描述（略）。 设计一个模拟的系统用户安全登录界面，采用MD5算法实现用户登录口令的安全认证。要求模拟界面至少具有用户口令文件的注册和用户登录时输入的口令是否正确的结果提示两个功能。 (MD5 algorithm description (abbreviated). The design of a simulation system security log user interface, using MD5 algorithm users log on password security authentication. Analog interface requirements at least a registered user password files and user login password is entered when the correct results suggest that the two functions.)
