Hypertext Transfer Protocol Secure (HTTPS)

Hypertext Transfer Protocol Secure (HTTPS) is also known as Secure Hypertext Transfer 

Protocol. It uses Secure Sockets Layer (SSL). Sometimes you’ll see it referred to as SHTTP 

or S-HTTP, which were slightly different protocols, but since Microsoft supported HTTPS, 

it became the de facto standard for securing web communication. But no matter—as indi-

cated, it’s a secure version of HTTP that arms you with a whole bunch of security tools for 

keeping transactions between a web browser and a server secure.

It’s what your browser needs to fill out forms, sign in, authenticate, and encrypt an 

HTTP message when you do things online like make a reservation, access your bank, or 

buy something.
