Certificate category-Root certificate generates the server certificate, which is the basis of the client certificate. Self-signed.-The server certificate is issued by the root certificate. configured on the server.-The client certificate is issued by the root certificate. Configured on the server, and sent to the customer, to allow customers to install in the browser. Be aware that1. The CN of the server certificate is consistent with ServerName, otherwise there is a warning when starting httpd.

Random numbers are widely used. They can be used to randomly display images. They can be used to prevent bored people from bumping in the Forum and encrypt information. This article discusses how to randomly generate several random numbers in a given number range. For example, randomly generate 6 random integers from 1 to 20, this article introduces the usage of random numbers in Visual C. . Net. frameword provides a special random generation class system. Random, which is imported by default
generation class System. Random, which is imported by default and can be used directly during programming. We know that a computer cannot generate completely random numbers. The numbers it generates are called pseudo-random numbers. They are selected from a group of finite numbers with the same probability, the selected number is not random, but its degree of randomness is sufficient.We can use the following two methods to initialize a random number generator;The function is used in this way, s

It consists of three parts: one islibcryto, This is a general function of the encryption library, which implements a large number of encryption libraries; secondlibsslThis implements the ssl mechanism.

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 FTP communication methods: One is implemented using SSL/TLS. The other is implemented through SSH + FTP. Here we will only introduce how to implement secure FTP communication throu

Also, all aspects of security need to be taken into consideration, especially when deploying a CA or PKI (public key Infrastructure). Of course, the benefits of security are self-evident, and improving the security of the enterprise network and system protects the enterprise from var
