SSL introduction SSL or Secure Socket Layer is a technology that allows web browsers and web servers to communicate through a secure connection. This means that the sent data is translated into a password at one end, sent out, unlocked at the other end, and then processed. This is a two-way process, that is, both the browser and the server need to encrypt the data before sending it. Another important aspect

HTTPS provides secure web traffic1. Principle part:1) Understand the encryption algorithm:Classification of cryptographic algorithms: symmetric and Asymmetric encryptionA. Symmetric encryption: Encryption and decryption using the same key, the advantage is fast, the disadvantage is that the key sharing difficulties. The typical symmetric encryption algorithm hasDes/aes/rc5/3des and so on.B. Asymmetric encryption: Generate a secret pair (public and pri

What does it mean to generate secure random data? Why generate secure random data? In some previous literature this was not a good indication of how to generate "safe" random numbers. So, here's how to safely generate random numbers in the programming language below. C + + Java . NET node. js PHP Python RubyGeneral conditions that need to be includedAll scenarios for this article must b

Tags: vsftpd + SSL Vsftpd + SSL/TLS for secure communication As mentioned in previous articles, FTP is transmitted in plain text, so it is easy for people to get their accounts and passwords. To implement secure FTP transmission, we need to use SSL/TLS to implement secure communication. Of course, there are two secure

Many users in the installation of win8.1 system, the default selection of the UEFI boot mode, after the system installation is completed, into the system desktop will appear in the lower right corner of a secure boot incorrectly configured watermark, for this problem is due to the user opened the UEFI mode, and did not open secure Boot settings caused by the following small series for you to provide a detai

web|xml| Security First of all introduce SSL, the English full name of SSL is "secure Sockets Layer", the Chinese name is "Secure Sockets Layer protocol layer", it is Netscape (Netscape) the security protocol based on WEB application. The SSL protocol can be divided into two tiers: the SSL record Protocol (SSL records PROTOCOL): It is built on a reliable transport protocol (such as TCP), providing support f

Web|web Service |web Server | security Update! A system that is not updated with the latest security patches will soon be called the attacker's target. After you have completed all the work required to configure your security system, remember that CGI scripts will be the biggest security risk. Most successful attacks are implemented through these scripts. The simple advice is to use CGI scripts that are publicly available and have been used by different websites for a while, and if administrato

The SSL (Security Socket Layer) protocol, designed and developed by Netscape, is used primarily to provide authentication to users and servers, to encrypt and hide transmitted data, to ensure that data is not altered in transit (i.e., data integrity) and is now a global standard in this field. Stunnel is a network data can encrypt the TCP connection tool, can work on UNIX, Linux and Windows platform, using Client/server mode, the ciient end of the network data using SSL encryption,

Last time we talked about the principles of HTTP data transmission. To improve the security of HTTP data transmission, Netscape developed the SSL protocol to ensure secure data transmission over the network. In addition, we have explained how to use the SSL protocol to implement the encrypted HTTP protocol transmission protocol-HTTPS, so that we can continue to complete the subsequent work. Access the Web Server1. Install (import) certificates for We

Secure Shell protocol (SSH) is a protocol that provides secure remote logon and other security network services on insecure networks. Secure Shell can be recorded as s h. It was originally a program on the u n I X system and then quickly expanded to other operating platforms. S h is a good application. When used correctly, it can make up for vulnerabilities in th
