The relationship between Https,http and SSL

What is the relationship between Https,http and SSL?

HTTP is a Hypertext Transfer protocol that allows a browser to access a variety of websites using this protocol.

SSL refers to secure Sockets layer, which is a secure and complete security protocol to ensure network data transmission.

HTTPS is a Hypertext Transfer protocol that adds a layer of encryption protocol on the basis of HTTP rules, and S refers to secure Socket layer,

HTTP data transmission is roughly the case: HTTP protocol encapsulated packets <-> TCP/IP <-> server, disadvantage: packets may be stolen or tampered with lost

The HTTPS approximate process is this: HTTP protocol encapsulated packet + SSL encryption <-> TCP/IP <-> Server disadvantage: Although security, but the overhead has become larger, the transmission speed is also slow.

If the HTTP transmission is likened to a data pipeline, SSL is the special protection layer of this pipeline, this SSL can not only protect the HTTP transmission, but also can be used in other data encryption transmission
