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.

1. In CentreWare Internet Services, click Properties > Security > Machine Digital Certificate

Management.

4. Click Continue.

5. Select Digital Signature Algorithms from the drop-down menu.

6. Select the Public Key Size and type the name of the Issuer.

7. Type the number of days between 1 and 9999 or until the certificate expires next to Days of

Validity.

8. Click Apply.
