SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral.
When a certificate is successfully installed on your server, the application protocol (also known as HTTP) will change to HTTPs, where the €˜S€™ stands for €˜secure€™. Depending on the type of certificate you purchase and what browser you are surfing the internet on, a browser will show a padlock or green bar in the browser when you visit a website that has an SSL Certificate installed.
