What is an SSL certificate?

An SSL certificate (also known as a TLS certificate) is a type of digital certificate that provides authentication for a server and enables an encrypted connection across the public internet. SSL certificates have a limited life – currently around 12 months – so once the certificate expires it will need to be renewed. The most common use is to secure a website, so that any confidential details passing over the internet (such as passwords) will be encrypted. A website that uses an SSL certificate can be identified by a padlock icon to the left of the address bar, with the https:// suffix on the URL.
