What is SSL? SSL stands for Secure Sockets Layer, an encryption technology that was originally created by Netscape in the 1990s. SSL creates an encrypted connection between your web server and your visitors' web browser allowing for private information to be transmitted without the problems of eavesdropping, data tampering, and message forgery.
To enable SSL on a website, you will need to get an SSL Certificate that identifies you and install it on your web server. When a web browser is using an SSL certificate it usually displays a padlock icon but it may also display a green address bar. Once you have installed an SSL Certificate, you can access a site securely by changing the URL from http:// to https://. If SSL is properly deployed, the information transmitted between the web browser and the web server (whether it is contact or credit card information), is encrypted and only seen by the organization that owns the website.

SSL vs. TLS
SSL and TLS generally mean the same thing. TLS 1.0 was created by RFC 2246 in January 1999 as the next version of SSL 3.0. Most people are familiar with the term SSL so that is usually the term that is used when the system is using the newer TLS protocol.

What is a certificate authority (CA)?
A certificate authority is an entity which issues digital certificates to organizations or people after validating them. Certification authorities have to keep detailed records of what has been issued and the information used to issue it, and are audited regularly to make sure that they are following defined procedures. Every certification authority provides a Certification Practice Statement (CPS) that defines the procedures that will be used to verify applications. There are many commercial CAs that charge for their services (VeriSign). Institutions and governments may have their own CAs, and there are also free Certificate Authorities.
