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 

 

A public key 

 

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

This printer supports two types of certificates. 
 

Device Certificate: This certificate contains a private key and a stated purpose that allows the 
printer to use it to prove identity. 

 

Trusted Certificate: A self-signed certificate is a certificate from a device that verifies its identity to 
any devices that connect to it. 

Note: 

This printer does not support Certificate Authority (CA) certificates. 

To ensure that the printer can communicate with other devices over a secure trusted connection, both 
devices must have specific certificates installed.
