What is SSL? SSL stands for Secure Sockets Layer. SSL creates an encrypted connection between your web server and your visitors' web browser allowing for private information to be transmitted without the problems of eavesdropping, data tampering, and message forgery.
When installed on a web server, it activates the padlock and the https protocol and allows secure connections from a web server to a browser. SSL is also used to secure credit card transactions, data transfer and logins.
You need to install the SSL Certificate onto your web server to initiate a secure session with browsers. Once a secure connection is established, all web traffic between the web server and the web browser will be secure.
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.
