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.
