Table 15-4 My Certificate Details 
LABEL DESCRIPTION 
Name 
This field displays the identifying name of this certificate. If you want to change the 
name, type up to 31 characters to identify this certificate. You may use any 
character (not including spaces). 
Property  
Default self-signed 
certificate which 
signs the imported 
remote host 
certificates. 
Select this check box to have the ZyWALL use this certificate to sign the trusted 
remote host certificates that you import to the ZyWALL. This check box is only 
available with self-signed certificates.  
If this check box is already selected, you cannot clear it in this screen, you must 
select this check box in another self-signed certificate’s details screen. This 
automatically clears the check box in the details screen of the certificate that was 
previously set to sign the imported trusted remote host certificates. 
Certification Path 
Click the Refresh button to have this read-only text box display the hierarchy of 
certification authorities that validate the certificate (and the certificate itself). 
If the issuing certification authority is one that you have imported as a trusted 
certification authority, it may be the only certification authority in the list (along with 
the certificate itself). If the certificate is a self-signed certificate, the certificate itself 
is the only one in the list. The ZyWALL does not trust the certificate and displays 
“Not trusted” in this field if any certificate on the path has expired or been revoked. 
Refresh 
Click Refresh to display the certification path. 
Certificate 
Information 
These read-only fields display detailed information about the certificate.  
Type 
This field displays general information about the certificate. “CA-signed” means 
that a Certification Authority signed the certificate. “Self-signed” means that the 
certificate’s owner signed the certificate (not a certification authority).  “X.509” 
means that this certificate was created and signed according to the ITU-T X.509 
recommendation that defines the formats for public-key certificates. 
Version 
This field displays the X.509 version number.  
Serial Number 
This field displays the certificate’s identification number given by the certification 
authority or generated by the ZyWALL. 
Subject 
This field displays information that identifies the owner of the certificate, such as 
Common Name (CN), Organizational Unit (OU), Organization (O) and Country (C). 
Issuer 
This field displays identifying information about the certificate’s issuing certification 
authority, such as Common Name, Organizational Unit, Organization and Country. 
With self-signed certificates, this is the same as the Subject Name field.
