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,

提供服务端登陆验证程序（验证码随机改变，防止非法进入）； 提供服务器控制程序，管理员可以允许、屏蔽和删除一个注册用户的登陆客户端； 任何改变访问地点的行为，都必须得到管理员的授权，否则无法登陆系统； 即使知道其他用户的密码也不能登陆系统。-provide certification services-landing procedures (Random Verification code change to prevent illegal entry); Provide server control procedures, administrators can allow, shielding and delete a user"s landing client; Any change in location of the visit have to be authorized administrators, whether while not landing systems; even if they know the password for other users can not landing system.
