In order to ensure data security in a particular environment, it is sometimes necessary to enable SSL functionality. The following is an example of a serv-u server that describes how to enable SSL encryption. Creating an SSL Certificate To use the Serv-u SSL feature, you will of course need the

In the past, I heard people say that an IP address can be used to generate a certificate. Today, the example shows that IP addresses cannot be used.Scenario 1: The name specified when the certificate is generated is IP Address The example is an example of single-point logon. The configuration in Web. XML is as follows: If the HTTPS protocol is specified in the above configuration and the name specified during certificate generation is 172.18.113.78, an error occurred while accessing the certi

1. HTTPS Concept 1) Introduction HTTPS (full name: Hypertext Transfer Protocol over Secure Socket Layer) is an HTTP channel targeted at security. It is simply a secure version of HTTP. That is, the SSL layer is added under HTTP. The Security Foundation of HTTPS is SSL, so the detailed content of encryption requires SSL. The system was initially developed by N

This article describes how to configure SSL support in Tomcat. 1. It is easier to configure SSL support in Tomcat. There are several steps: (1) If the JVM version is earlier than 1.3, You need to download JSSE, which is a Java SSL support library. Since JDK 1.4, JSSE has been built into JDK. Therefore, this step can be omitted. (2) execute the command (in Linu

MINA, Netty, and Twisted: SSL/TLS, nettytlsWhat is SSL/TLS? Network Communication without SSL/TLS is generally transmitted in plain text. The content transmitted over the network is easily eavesdropped or tampered with during transmission, which is extremely insecure. The SSL/TLS protocol is designed to solve these sec
