Digital Certificates
A digital certificate must be installed on the printer before you can enable secure HTTP (SSL). A digital
certificate is the data used to verify the identity of the holder or sender of the certificate. A certificate
includes the following data:
•
Information about the person, organization, or computer that the certificate is issued to, including
the name, location, email address and other contact information.
•
Serial number of the certificate
•
Expiration date of the certificate
•
Name of the certificate authority (CA) that issued the certificate
•
A public key
•
Digital signature of a CA
Installing a Digital Certificate
There are three ways to install a certificate on the printer:
•
Create a Self-Signed Certificate. The printer creates its own certificate, signs it, and creates a
public key to be used for encryption.
•
Create a request to have a certificate authority, or a server functioning as a certificate authority
sign a certificate and then upload the certificate to the printer. An example of a server functioning
as a CA is Windows Server running Certificate Services.
•
Install a certificate created by a trusted intermediate or root CA. For details, see
Managing
Certificates
on page 49.
Note:
Installing a self-signed certificate is less secure than installing a certificate signed by a
trusted CA. However, if you do not have a server functioning as a certificate authority, the self
signed certificate is your only option.
