SSL Certificates are small data files that digitally bind acryptographic key to an organization’s details. 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. Typically, SSL is used to secure credit card transactions, data transfer and logins, and more recently is becoming the norm when securing browsing of social media sites.
SSL Certificates bind together:
- A domain name, server name or hostname.
- An organizational identity (i.e. company name) and location.
An organization needs to install the SSL Certificate onto its 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
As the highest ‘class’ of SSL available, Extended Validation SSL Certificates (EV SSL) activate both the padlock and the green address bar in all major browsers. EV SSL Certificates provide the strongest encryption level available and enable the organization behind a website to present its own verified identity to website visitors.
