　　Background introduction Recently in the "Cryptography and Cyber Security" related books, this article is mainly about the famous Network security protocol SSL. Before beginning the introduction of SSL, we will introduce a few cryptography concepts and related knowledge. 1. Cryptography Related Concepts Cryptography (Cryptography): The goal is to achieve security by encoding the information so th

Recent projects in the company involve a variety of encryption and security. I have always lacked experience in this area. It is a protocol that only knows what the concept is. Encrypted SSL for transport is also a painstaking. Very easy one thing, tossing for a long time. It's the line, really. The difficulty is not, the participants are difficult.About SSL-related concepts. The following website:Http://zh

SSL (secure Sockets layer), and its successor, TLS (Transport layer Security, Transport layer safety) is a security protocol that provides security and data integrity for network communications. TLS encrypts the network connection with SSL at the transport layer.Developed for Netscape to secure data transmission over the Internet, the use of encryption (encryption) technology ensures that data is not interc

The following is a Java certificate: HTTPS and SSL application notes test. I hope this article will help you. When a connection is obtained, like a normal browser, the server certificate is still verified to be trusted (issued by an authority or signed by an authority). If the server certificate is untrusted, the default implementation will be problematic. Generally, errors are often reported when java accesses the

What is SSL?Originally developed by the Netscape Enterprise, the Secure Socket Layer (SSL) protocol is now a global standard for authenticating Web sites and web browser identities, and for encrypting communications between users of browsers and Web servers. Because SSL technology is built into all major browsers and Web server programs, you can only install digi

SSL certificates have become very popular. For example, Let's Encrypt Free SSL, which was prepared for sharing later, has started public beta and has been recognized by most third-party browsers and authoritative websites, therefore, if we need to use SSL certificates to implement the https url format for our website in the future, there are still many free

First, you need to understand some basic concepts before installing 1. Certificates used by SSL can be self-generated or signed by a commercial ca such as Verisign or thawte. 2. Certificate concept: First, you must have a root certificate, and then use the root certificate to issue the server certificate and customer certificate. Generally, the server certificate and customer certificate are in a hierarchical relationship. The root certificate and

About SSL Certificates I have written two articles, one is Nginx configuration, one is Tomcat configuration, HTTPS is very common.according to Let's Encrypt CA statistics, as of November 2017, Firefox-loaded web pages with HTTPS-enabled ratios accounted for 67%, a huge boost compared to 45% at the end of last year. Browser developers like Mozilla, Google is ready to take the next step: to mark all HTTP sites as unsafe.with The popularization of HTTPS,
