SSL is a commonly used WEB Service encryption channel. Its full name is Secure Socket Layer, which is also known as the Secure sockets interface. It uses digital certificates to ensure its security mechanism. The main function is encryption and authentication to protect the security of network transmission. It is in the middle of the HTTP and TCP layers.
SSL encryption and authentication use public keys and
lower than that of symmetric encryption and decryption algorithms. Therefore, SSL uses asymmetric cryptographic algorithms to negotiate keys during the handshake process, and uses symmetric encryption and decryption methods to Encrypt transmission of HTTP content. The following is a metaphor for the image of this process (from http://blog.chinaunix.net/u2/82806/showart_1341720.html ):
Assume that a communicates with B, A is an

(also the TCP client) sends a Clienth*llo after the TCP link is established, which contains the list of algorithms that it can implement and some other required messages.2. The server side of SSL responds to a Serverh*llo, which determines the algorithm required for this communication, and then sends its own certificate (which contains the identity and its own public key).3. When the client receives this m

To better understand and understand the SSL protocol, we will introduce the handshake protocol of the SSL protocol. SSL uses both public key encryption and symmetric encryption. Although symmetric encryption is faster than public key encryption, public key encryption pr
At present, there are various types of websites. When we enter personal information on some websites, especially online banking transactions, how can we ensure that the websites you are facing are credible? By using the SSL Certificate of the website ID card, we can clearly understand whether the website is secure and trustworthy. Generally, the browser determines the security of these certificates. If we c

Introduction (Creating a generated certificate can only be used for test use.) If you want to use a self-signed certificate, you can only issue certificates to the CA authority for two-way authentication to use.

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
