ARCHIVE / What is SSL?
SSL is an abbreviation for Secure Sockets Layer which is a protocol for encrypting communications over computer networks. SSL was the first encryption protocol to be used by web sites allowing encrypted web page requests and responses. It has to some extent been subsumed by TLS, short for Transport Layer Security, which extends SSL with support for more effective cryptographic algorithms. However, because fewer people are familiar with the TLS abbreviation, SSL is often used to refer to both protocols.
