TEA介绍及数据加密算法之程序代码

一个DES加密算法的实现-a DES encryption algorithm implementation

这是用C编写的命令加密法算法，请大虾们指教。-This is prepared by using C commands encryption algorithm, please advise their shrimp.

把信息隐藏到图片中，比加密更安全-hidden message to the pictures, more secure encryption

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.
