X.509 Certificates


A Secure Socket Layer (SSL) certificate is a security protocol which
secures data between two computers by using encryption. Typically, SSL
certificates are used on web pages that transmit and receive end-user
sensitive data. SSL certificates ensure the identity of a remote
computer, most commonly a server, but also confirms your computer’s
identity to the remote computer to establish a safe connection.
