Security 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

There are three types of certificates:

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.

A CA Certificate is a certificate with authority to sign other certificates.

A Trusted Certificate is a self-signed certificate from another device that you want to trust.
