Https SSL/TLS

SSL is the abbreviation for foreign language "secure Sockets layer", which is called "Secure Sockets Layer" in Chinese.

It was designed by Netscape in the middle of the 90 century. (Incidentally, Netscape not only invented SSL, but also invented a lot of Web infrastructure-such as "CSS stylesheets" and "JS scripts").
Why to invent SSL this protocol pinch? Because the HTTP protocol used on the internet is plaintext, there are a number of drawbacks-such as the fact that the transmitted content is peeping (sniffing) and tampering. The invention of the SSL protocol is to solve these problems.
By the year 1999, SSL has become a de facto standard on the Internet because of its wide application. The IETF standardized SSL in that year. The name after normalization is changed to TLS (the abbreviation for "Transport Layer Security"), and Chinese is called the "Transport Layer secure Protocol".
Many of the related articles refer to these two terms (SSL/TLS) because they can be regarded as different stages of the same thing.

After explaining SSL/TLS, you can now explain HTTPS. What we usually call the HTTPS protocol, is plainly the combination of "HTTP protocol" and "SSL/TLS protocol". You can roughly understand HTTPS as-"http over SSL" or "HTTP over TLS" (SSL and TLS, anyway).
