What is a Secure Socket Layer (SSL) certificate?
The purpose of SSL is to transmit sensitive data over the Internet.The primary reason why SSL is used is to keep sensitive information sent across the Internet encrypted so that only the intended recipient can understand it. This is important because the information you send on the Internet is passed from computer to computer to get to the destination server.
A digital certificate is simply a statement digitally signed by an independent and trusted third party (the certificate authority). That statement usually follows a very specific format laid down in a standard called X.509; hence, they are sometimes referred to as X.509 certificates. A certificate is required to establish an authenticated and encrypted communications channel between the registrar’s server and .ORG SRS.
