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.)
