HTTP It is a transport protocol that we often used for a long time in the past. The data transmitted by the HTTP protocol is unencrypted, which means that the password, account number, transaction record and other confidential information filled in by the user are in clear text, which may be disclosed, stolen, tampered with at any time, and used by hackers. Therefore, the transmission of private information by the HTTP protocol is very insecure.

HTTPS It is a website encryption transmission protocol based on the SSL protocol. After the website is installed with an SSL certificate, it can be accessed using the HTTPS encryption protocol, which can activate the "SSL encryption channel" (SSL protocol) between the client browser and the website server to achieve high strength two-way encryption transmission and prevent the transmission data from being leaked or tampered with. In brief, HTTPS=HTTP+SSL is the secure version of HTTP.
