From: http://blog.csdn.net/lele5000/article/details/6704247 Preface: The implementation of MD5 and base64 functions is not the focus of this article. The focus is on the trouble of Character Set conversion during implementation.   Recently, due to

How can I encrypt my website registration and login password? I have read many articles in this regard on the Internet, all of which refer to the client password. when logging on, I will use md5 encryption to send it to the server, and then compare

Newbie Tom asks questions about the session. what I want to achieve is to prevent users from logging on repeatedly. I don't understand the advanced method. I will only use what I can understand. thank you! First login page If (! $ Username) {$

SIP is similar to HTTP protocol. The authentication mode is also the same. The HTTP protocol (RFC 2616) stipulates that the base mode and digest mode can be used ). RFC 2617 specifies two authentication modes. RFC 1321 is the MD5 standard. Digest is

由于公司运营管理岗位变动，删除账户会造成操作日志操作人为空的现象，为了保留管理账号完整，又不要他登陆管理，虽然可以更改后台管理的链接，但为了更安全，所以公司要求实现管理员状态设置，可以自由变更管理员的登录状态。一下是删除管理员账号操作日志造成的问题： 下面是添加成功后的展示图： 一、执行数据库语句，添加状态字段：其中ecs_为数据库前缀 ALTER TABLE `ecs_admin_user` ADD `status` SMALLINT( 3 ) UNSIGNED NOT NULL

There are md5.c and md5.h online, but there are only MD5Init (), MD5Update (), and MD5Final () functions, Only the characters can be operated directly, but there is no interface for directly obtaining file md5. The following is my implementation,

I have never been very clear about cookie and session mechanisms. Are there any good materials for me to learn, I am very grateful to you for your understanding of cookie and session mechanisms. I am very grateful if I have any good information to

The common encryption algorithms can be divided into three kinds, symmetric encryption algorithm, asymmetric encryption algorithm and hash algorithm. Symmetric encryption Encrypt and decrypt encryption algorithms that use the same key. The
