What Is SSL (Secure Socket Layer)?

This section provides a quick introduction of the SSL (Secure Socket Layer) protocol, which provides security protection on data being transferred over the Internet.

What is SSL (Secure Socket Layer)? SSL is a communication protocol created by Netscape in 1994 to ensure secure transactions between web servers and browsers. A good description about SSL was given by Franck Martin in "SSL Certificates HOWTO" at http://www.tldp.org/HOWTO/SSL-Certificates-HOWTO:

The latest version of SSL is version 3.0 which was defined in 1996. A new protocol called Transport Layer Security (TLS) has been developed to replace SSL.
