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.

Valid From

This field displays the date that the certificate becomes applicable. The text

displays in red and includes a Not Yet Valid! message if the certificate has not yet

become applicable.

Valid To

This field displays the date that the certificate expires. The text displays in red and

includes an Expiring! or Expired! message if the certificate is about to expire or

has already expired.

Modify

Click the details icon to open a screen with an in-depth list of information about the

certificate (or certification request).
Click the export icon to save the certificate to a computer. For a certification

request, click the export icon and then Save in the File Download screen. The

Save As screen opens, browse to the location that you want to use and click

Save.
Click the delete icon to remove the certificate (or certification request). A window

displays asking you to confirm that you want to delete the certificate.
You cannot delete a certificate that one or more features is configured to use.
Do the following to delete a certificate that shows *SELF in the Type field.
1. Make sure that no other features, such as HTTPS, SSH are configured to use

the *SELF certificate.
2. Click the details icon next to another self-signed certificate (see the description

on the Create button if you need to create a self-signed certificate).
3. Select the Default self-signed certificate which signs the imported remote

host certificates check box.
4. Click Apply to save the changes and return to the My Certificates screen.
5. The certificate that originally showed *SELF displays SELF and you can delete

it now.
Note that subsequent certificates move up by one when you take this action.
The poll now icon displays when the ZyXEL Device generates a certification

request successfully but the CA does not issue a certificate and sends a pending

notification to the ZyXEL Device. If the icon displays, you can manually click the

icon to have the ZyXEL Device query the CA (or RA (Registration Authority))

server for a certificate immediately. Otherwise, the ZyXEL Device checks with the

server and updates the status periodically. The poll now icon disappears after the

ZyWALL gets a certificate or the request has failed permanently due to being

rejected by the CA server.

enrolled from a certification authority from your computer to the ZyXEL Device.

Create

a certificate or a certification request.
