SSL (Secure Sockets Layer) is a standard security protocol used to establish encrypted links between web servers and web browsers. This helps ensure that whatever communication occurs between a web server and a web browser remains encrypted and totally private. This technology, which has become an industry standard today, is used by websites to protect all communication and data transmitted online. Even the ordinary internet user today looks for the HTTPS in the address bar; the HTTPS is what indicates the presence of SSL certificate for any website.”]
