SSL certificates are used to establish a secure connection between a web server and a web browser. This secure connection is created through a process called SSL/TLS (Transport Layer Security) handshake. SSL certificates ensure that any data transmitted between the server and the browser remains private and secure, and cannot be intercepted by unauthorized third parties.
When a website has an SSL certificate installed, it will display a padlock icon in the browser's address bar, indicating that the site is secure. Some SSL certificates also display a green address bar, which provides additional reassurance to website visitors.
There is various SSL certificate authorities (CAs) that issue SSL certificates, including Symantec, Thawte, Comodo, Setigo, GeoTrust, and Rapid SSL. Each CA has its own validation process and pricing model, so it's important to choose the right SSL certificate based on your business needs and budget.
The process for installing an SSL certificate depends on the provider that you purchased it from. Some providers will streamline installation or take care of it for you. If you need to install the certificate manually, the steps are dependent upon your platform and operating system.
SSL renewal keeps your encryption and ciphers up to date, keeping your website and customers safer. Keep on top of renewals to avoid the mistake of letting your certificates expire.
