What is the difference between HTTP and HTTPS protocols?

Defined:

HTTP (Hypertext Transfer Protocol) is a Hypertext Transfer Protocol, a rule that specifies the communication between the browser and the World Wide Web server, transmitting the data transfer Protocol of the World Wide Web document over the Internet. HTTPS is actually a secure HTTP protocol, which is the secure version of HTTP plus SSL.

The same point: protocols are used at the application layer to specify rules for the browser and the World Wide Web server to communicate with each other.

Different points:

1, HTTP is plaintext transmission, and HTTPS is encrypted by SSL.

2. HTTP is a simple connection with no state.

3, the port number is different: The port number of HTTP is 80, and the port number of HTTPS is: 443.

4. The HTTPS protocol requires a certificate to be applied to the CA, while HTTP is not required.
