Table 4-16 Certificate configuration screens (continued)
●
Update Pre-Installed Certificate Update the pre-installed, self-signed certificate. The certificate is
overwritten. You can update the following items:
Certificate Validity Period
The browser identifies the certificate as self-signed for each new Web session, which can cause a security
alert message. You can bypass this message by adding the certificate to the browser's certificate store or
by disabling browser alerts (not recommended).
Self-signed certificates are not necessarily secure because the certificate owner is merely confirming his
own identity instead of verification by a trusted third party. Certificates from a trusted third party are
considered more secure.
Encryption Key Length
Select whether to use 1024 bit or 2048 bit encryption key length.
●
Create Certificate Request You are prompted for specific device and organizational information in the
following screen:
Certificate Information
Use this option when an authentication protocol requires that you install an HP Jetdirect certificate issued
by a trusted third party or certificate authority.
●
Install Certificate Displayed only if there is a pending HP Jetdirect certificate request (to a trusted third
party). When the certificate is received, use this option to install it. Once installed, this certificate overwrites
the pre-installed certificate. You are prompted for information in the following screen:
Install Certificate
The certificate to be installed must be associated with a previous certificate request generated by the
HP Embedded Web Server.

HP Jetdirect print server. Displayed when a CA certificate for EAP authentication is installed.

The CA Certificate is also removed on a cold-reset of the print server, where factory-default settings are
restored.
