HTTPS
Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP) for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS), or, formerly, its predecessor, Secure Sockets Layer (SSL). The protocol is therefore also often referred to as HTTP over TLS, or HTTP over SSL.
Transport Layer Security
TLS is a proposed Internet Engineering Task Force (IETF) standard, first defined in 1999 and updated in (August 2008) and (March 2011). It builds on the earlier SSL specifications (1994, 1995, 1996) developed by Netscape Communications
for adding the HTTPS protocol to their Navigator web browser.
