Using the Embedded Web Server 65

Certificates

This tab provides access to installation, configuration and management
services for X.509 digital certificates. A digital certificate is an electronic
message typically containing, among other things, a key (a short string used
for encryption and decryption) and a digital signature. Certificates may be
issued and signed by a trusted third party (commonly called a Certificate
Authority, or CA), which may exist internal or external to the organization.
Or certificates may be “self-signed”, which is similar to validating your own
identity.

Note

While self-signed certificates are permitted and allow data
encryption, they do not ensure valid authentication.

The Certificates page provides the status of the certificates installed on the
HP Jetdirect projector server:

Jetdirect certificate. The Jetdirect certificate is used to validate the
identity of the Jetdirect device to clients and to network authentication
servers.

By factory default, a self-signed Jetdirect certificate is preinstalled. This
allows the embedded Web server to use HTTPS and appear as a secure site
when accessed by a Web browser.

Click View to view the contents of an installed Jetdirect certificate, or click
Configure to update or install a new one. See “

Configuring Certificates

.”

When installed, a Jetdirect certificate will be saved across a cold-reset,
which is used to restore the projector server to factory-default values.

CA Certificate. A certificate from a trusted third party, or Certificate
Authority (CA), is used to validate the identity of a network authentication
server during 802.1X authentication methods that use EAP (Extensible
Authentication Protocol). The authentication server’s identity is validated
when information on the CA certificate matches the information on a
certificate received from the authentication server.

A CA certificate for the projector server is a certificate that was used to
sign the authentication server’s certificate. Therefore, the Certificate
Authority for the authentication server’s certificate must also be used for
the CA certificate.
