About Certificates

A digital certificate is a file that contains data used to verify the identity of the client or server in a

network transaction. A certificate also contains a public key used to create and verify digital signatures.

One device proves its identity to another by presenting a certificate trusted by the other device. Or, the

device can present a certificate signed by a trusted third party and a digital signature proving its

ownership of the certificate.

A digital certificate includes the following data:

• Information about the owner of the certificate

• The certificate serial number and expiration date

• The name and digital signature of the certificate authority (CA) that issued the certificate

• A public key

• A purpose defining how the certificate and public key can be used

The printer supports three types of certificates. You can create a self-signed certificate, or install a root

certificate or a certificate signed by a certificate authority (CA).

• A Device Certificate is a certificate for which the printer has a private key. The purpose specified in

the certificate allows it to be used to prove identity.

• The printer generates a default self-signed certificate during its first startup.

• A CA Certificate is a certificate with authority to sign other certificates. The device certificate signed

by a CA validates the identity of the printer to the network.

• A Root or Trust Point Certificate is a self-signed certificate from another device that you want to

trust.
