Secure Sockets Layer, or SSL, is a protocol employed to encrypt the information exchanged between a hosting server and its users. The practical application of employing an SSL is to secure the information which clients submit on your site - a login page, a payment page if you run a web-based store, and so forth. Any information they type in in any box on the website shall be submitted safely to the server, so their login or payment data shall be protected from being accessed by unauthorized people. Usually, an SSL certificate requires a dedicated IP address to be installed, meaning that the overall cost for your online presence shall be higher. While this may not be a problem for a larger enterprise, it might matter for a non-profit organization or a small web store that does not generate big profits if additional money should be spent. That's the reason why we have taken advantage of an extension called Server Name Indication (SNI) and we have made it possible to use a shared server IP address to install an SSL certificate.
