About 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:
• Device Certificate: A certificate for which the printer has a private key, and the purpose specified in
the certificate allows it to be used to prove identity.
• CA Certificate: A certificate with authority to sign other certificates.
• Trusted Certificate: A self-signed certificate from another device that you want to trust.
To ensure that the printer can communicate with other devices over a secure trusted connection, both
devices must have certain certificates installed.
For protocols such as HTTPS, the printer is the server, and must prove its identity to the client Web
browser. For protocols such as 802.1X, the printer is the client, and must prove its identity to the
authentication server, typically a RADIUS server.
