What is a digital key and a certificate?

SSL uses a public-private key system for encryption. The public key is used to encrypt all the information. However, only the private key can be used to decrypt this information. This allows the public key to be known to all so that encrypted information may be sent to the server. The server can then use the private key, which is kept secret, to decrypt information.

In this scenario, the certificate is the public key, and it is issued by us. The public and private keys compose the digital key pair.
