ssl for subdomain

Based on the previous security protocol analysis of the SSL protocol, first review the content of the SSL protocol and then use Wireshark to grasp the contents of the specific flow of packets. The SSL protocol stack is located between the TCP and the application layer, and is divided into the SSL record protocol layer

Some people say that SSH is generally used to provide secure login. SSL is only a layer added to the protocol layer to provide security. SSH works on TCP. After an SSH application is started, other protocol applications, such as emails, can be run in the channel. SSL can be considered as if the application itself supports SSL, then it automatically uses the

Now, some companies have begun to consider using the SSL protocol on the Internet without disrupting the existing network layout..

SSL protocol workflow: Server Authentication phase:1)The client sends a start message "hello" to the server to start a new session connection;2)The server determines whether to generate a new CMK based on the customer's information. If necessary, the server will include the information required to generate the CMK in response to the customer's "hello" information;3)The customer generates a master key based on the server response information and encr

The emphasis of this article is on the design idea and the running process,

SSL/TLS is no longer a strange word, but its principles and rules are not too easy to remember. This article will try to show the principle of the process through some simple illustrations, hoping that the reader has something to gain.first, the relevant version Version Source Description Browser support SSL v2.0 Vendor Standard (from Netscape

IntroductionTLS, or transport Layer Security, and its predecessor SSL, which stands for Secure Sockets Layer, is Web protocols used T o Wrap normal traffic in a protected, encrypted wrapper.Using This technology, servers can send traffic safely between the server and the client without the concern, the mess Ages'll is intercepted and read by a outside party.

SSL Certificate The SSL certificate is designed and developed by the Netscape Communication Company by establishing an SSL secure channel between the client browser and the Web server (Secure Socket Layer (SSL) security protocol. This security protocol is primarily used to provide authentication to users and

Install mod_ssl Apache2 has built-in mod_ssl, so you only need to add parameters during compilation: -- Enable-SSL = static -- With-SSL =/usr/local/SSL Explanation: Compile mod_ssl statically before it can be used normally. Otherwise, Apache will prompt an error at sta

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,
