Managing Certificate Authorities

A certificate authority (CA) is a trusted entity that issues digital certificates that verify a digital entity’s identity. Digital certificates are an integral part of secure communication and play an important part in the public key infrastructure (PKI). Certificates typically include the public key, the expiration date of the certificate, the owner's name and other information about the certificate owner. Operating systems (OSes) and browsers maintain lists of trusted CA root certificates to verify the identity and validity of certificates that a CA has issued and signed. Certificate Authorities are enabled by the System Administrator.
