20.2.1  The My Certificate Details Screen
Click SECURITY CERTIFICATES > My Certificates to open the My Certificates 
screen (see 
). Click the details icon to open the My Certificate Details 
screen. You can use this screen to view in-depth certificate information and change the 
certificate’s name. 
If it is a self-signed certificate, you can also set the ZyWALL to use the certificate to sign the 
imported trusted remote host certificates. 
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, VPN, 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 ZyWALL generates a certification request 
successfully but the CA does not issue a certificate and sends a pending 
notification to the ZyWALL. If the icon displays, you can manually click the icon to 
have the ZyWALL query the CA (or RA (Registration Authority)) server for a 
certificate immediately. Otherwise, the ZyWALL 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.
Import
Click Import to open a screen where you can save the certificate that you have 
enrolled from a certification authority from your computer to the ZyWALL.
Create
Click Create to go to the screen where you can have the ZyWALL generate a 
certificate or a certification request.
