Secure Sockets Layer (SSL) is a security protocol that provides an encrypted Internet connection. An SSL certificate is proof from an independent third party that your website belongs to the organization it says it does and that your users will be transmitting information via an encrypted connection. You should use an SSL certificate to protect any website or service that handles sensitive data such as login credentials.

Certificates can also be used to sign documents electronically or to sign code for distribution.
