Introduction to HTTPS protocol
As a secure HTTP data transmission protocol, HTTPS is widely used in the communication of information on the World Wide Web. At present, most websites use the HTTPS protocol to transmit information.

HTTPS protocol and TLS protocol
The HTTP protocol is mainly used for the server and the client, that is, the system transmission hypertext transfer protocol of the C/S mode architecture.
The HTTP protocol data processing speed is fast, but the disadvantage is that the communication process uses clear text to transmit the client request and server response messages. Therefore, there are risks of information eavesdropping, information tampering and information hijacking. Therefore, the HTTPS protocol was born, and HTTPS is based on the HTTP protocol.
The security foundation of HTTPS is SSL/TLS. TLS is a layer of security protocol between TCP and HTTP, and does not affect the original TCP protocol and HTTP protocol, so using HTTPS basically does not require too many changes to the HTTP page. TLS provides security services for the application layer. Its goal is to ensure the confidentiality and reliability of communication between two applications, and it can be supported at both ends of the server and client. At present, almost all browsers such as Firefox, Netscape, and IE support the SSL/TLS protocol to achieve communication security.
