What is SSL Certificate?

Before going into pricing discussion, lets understand what is SSL certificate. SSL in ‘SSL Certificate’ stands for Secure Sockets Layer. It encrypts information sent to the server using SSL technology. Lets say you are sitting in front of your laptop ordering daily grocery items. When you enter your credit card details to process payment, it is sent to server for verification. While data is sent to server, you may think of a hacker filtering your data and can steal your card details. Here the SSL encrypts your input data into indecipherable format and it will be decryption on server and then processed/verified.

Does SSL Need Dedicated IP Address:

Answer to this question could both ‘Yes’ and ”No’. Actually it depends upon your server configuration. Let us explain more why answer it to both Yes and No:

YES: When a client (Browser sends a https request to a server with IP address xxx.xxxx.xxx.xxx, and it has more than one SSL certificates installed on it, it does not know which certificate to present. Thus the server is required to have only one certificate.

NO: While looking for alternative to the above issue, developer found a solution to it called SNI (Server Name Indication).  It indicates which hostname is requested by the client (browser) at the beginning of the handshake process.
