An x.509 certificate includes the format of the certificate, the serial number of the
certificate, the algorithm used to sign the certificate, the name of the CA that issued the
certificate, the name and public key of the entity requesting the certificate, and the CA's
signature.x.509 certificates are used to authenticate the remote party against a
Certificate Authority's (CA) certificate. The CA certificate must have signed the local

the UTM Firewall appliance before a tunnel can be configured to use them.
