First, the key introduction: under Linux, the remote login system has two authentication methods: Password authentication and key authentication. The method of password authentication is a traditional security policy. Set a relatively complex password, the security of the system can play a certain role, but also fac
Author: limodounbsp; I have previously written an article about how to use socket programming to send emails to solve the problem that web servers do not support the mail () function. It can also be used after my tests. However, at present, many free email providers (starting from 263, 163, and xinlang net) all add smtp functions.

I believe everyone remembers a classic cartoon. A dog typed in front of a computer and said to another dog, "no one knows whether you are a dog or not on the Internet!" This cartoon shows that it is difficult to identify on the Internet.
Identity Authentication refers to the process in which the computer and network system confirm the identity of the operator. Computer systems and networks are a virtual digital world. In this digital world, all inform
Basic authentication is convenient and flexible, but extremely unsafe. The user name and password are transmitted in clear text, and no action is taken to prevent tampering with the message. The only way to safely use Basic authentication is to use it in conjunction with SSL.Abstract authentication is another HTTP authenticat

The problem was ruled out.Next I want to take a closer look at response, can you find any clues. Carefully check the response header and body, found that the header everything is normal, body is an empty body, no information available.Then another solution I could think
}.3."Last Modified Time" represents the number of days from the time the user last modified the password. The beginning of time may not be the same for different systems. In Linux, for example, the starting point for this time is January 1, 1970.4."Minimum time interval" refers to the minimum number of days required between changing the password two times.5."Maximum time interval" refers to the maximum number of days the password remains valid.6. The"Warning Time" field represents the number of
Users often need to restrict access to certain important files or information when designing and maintaining a site. In general, we can use the HTTP protocol based user authentication mechanism built into the Web server. When a visitor browses to a protected page, the client browser pops up a dialog window requiring the user to enter a username and password and authenticate the user to determine whether the user has access to the page. The following t

Shiro is an Apache incubator project designed to simplify authentication and authorization. In this article, learn about Apache Shiro and use an example to try to authenticate and authorize using Shiro in a Groovy Web application.

SSH principles and Public Key Authentication
Creation process
Ssh uses the asymmetry of rsa encryption to share a communication key that only the two of them know. Through this communication key, they then perform subsequent communication.
The client receives the public key of the server and encrypts the Communication Key generated by the client to the server. The server decrypts the key with a private key. At this time, the two use symmetric keys for

Frequent users of the Internet will encounter this situation: When accessing some of the site's resources, the browser pops up a dialog box that asks for a user name and password to gain access to the resource. This is a technology of user authentication. User authentication is the first line of defense to protect network system resources, it controls all logins and checks the legitimacy of access us

This is a technology used for user authentication. User authentication is the first line of defense to protect network system resources. It controls all logins and checks the validity of users, the goal is to only allow legal users to access network system resources with legal permissions. The basic user authentication technology is "User Name + password ".

Through the above introduction, we found that Kerberos is actually based onTicket. To obtain Server resources, the Client must first pass Server Authentication. A prerequisite for authentication is that the Client provides the Server withMaster Key of the ServerEncryptedSession Ticket (Session Key + Client Info). In this case, Session Ticket is a Ticket for the Client t

With the development of the Internet, the complexity of Web applications has been improving, and a single Web application has been unable to meet complex business requirements. For example, Baidu's search, news, encyclopedia, bar Paste, in fact, are different sites. When users use these platforms, we certainly do not want users to have a separate account on each platform, otherwise users and developers may be tempted to cry. So we need a system where a user can log in once to access all of the t
The security mechanism for implementing Web applications is the task that designers and programmers of Web applications must face. In Java EE, the Web container supports the security mechanism built into the application.
The security mechanism for Web applications has two components: Authentication and authorization. The Web container based on Java EE provides three kinds of authentication mechanisms: Basi
valid, the Web server will allow the user to enter the protected area and maintain the validity of its identity throughout the access process. Conversely, if a user enters a user name or password that is not authenticated, the client browser pops up the input window and asks the user to try to enter the correct information again. The entire process will continue until the user enters the correct information location, or it can set the maximum number of times the user is allowed to try, and the
