43.12.4 The Trusted Certificates Screen
Click Configuration > Object > Certificate > Trusted Certificates to open the Trusted Certificates screen.
This screen displays a summary list of certificates that you have set the Zyxel Device to accept as trusted.
The Zyxel Device also accepts any valid certificate signed by a certificate on this list as being
trustworthy; thus you do not need to import any certificate that is signed by one of these certificates.
Figure 619 Configuration > Object > Certificate > Trusted Certificates
The following table describes the labels in this screen.

created when the PKCS #12 file was exported.
OK Click OK to save the certificate on the Zyxel Device.
Cancel Click Cancel to quit and return to the My Certificates screen.

PKI Storage Space
in Use
This bar displays the percentage of the Zyxel Device’s PKI storage space that is currently in
use. When the storage space is almost full, you should consider deleting expired or
unnecessary certificates before adding more certificates.
Edit Double-click an entry or select it and click Edit to open a screen with an in-depth list of
information about the certificate.
Remove The Zyxel Device keeps all of your certificates unless you specifically delete them. Uploading a
new firmware or default configuration file does not delete your certificates. To remove an
entry, select it and click Remove. The Zyxel Device confirms you want to remove it before
doing so. Subsequent certificates move up by one when you take this action.
References You cannot delete certificates that any of the Zyxel Device’s features are configured to use.
Select an entry and click References to open a screen that shows which settings use the entry.
# This field displays the certificate index number. The certificates are listed in alphabetical order.
Name This field displays the name used to identify this certificate.
Subject This field displays identifying information about the certificate’s owner, such as CN (Common
Name), OU (Organizational Unit or department), O (Organization or company) and C
(Country). It is recommended that each certificate have unique subject information.
Issuer This field displays identifying information about the certificate’s issuing certification authority,
such as a common name, organizational unit or department, organization or company and
country. With self-signed certificates, this is the same information as in the Subject field.
