LABEL DESCRIPTION
Certificate Name
Type up to 31 ASCII characters (not including spaces) to identify this certificate.
Subject Information
Use these fields to record information that identifies the owner of the certificate. 
You do not have to fill in every field, although the Common Name is mandatory. 
The certification authority may add fields (such as a serial number) to the subject 
information when it issues a certificate. It is recommended that each certificate 
have unique subject information. 
Common Name Select a radio button to identify the certificate’s owner by IP address, domain
name or e-mail address. Type the IP address (in dotted decimal notation), 
domain name or e-mail address in the field provided. The domain name or e-mail 
address can be up to 31 ASCII characters. The domain name or e-mail address 
is for identification purposes only and can be any string. 
Organizational Unit Type up to 127 characters to identify the organizational unit or department to
which the certificate owner belongs. You may use any character, including 
spaces, but the ZyWALL drops trailing spaces. 
Organization Type up to 127 characters to identify the company or group to which the
certificate owner belongs. You may use any character, including spaces, but the 
ZyWALL drops trailing spaces. 
Country Type up to 127 characters to identify the nation where the certificate owner is
located. You may use any character, including spaces, but the ZyWALL drops 
trailing spaces. 
Key Length
Select a number from the drop-down list box to determine how many bits the key 
should use (512 to 2048). The longer the key, the more secure it is. A longer key 
also uses more PKI storage space. 
These radio buttons deal with how and when the certificate is to be generated.
Create a self-signed 
certificate 
Select Create a self-signed certificate to have the ZyWALL generate the 
certificate and act as the Certification Authority (CA) itself. This way you do not 
need to apply to a certification authority for certificates. 
Create a certification 
request and save it 
locally for later manual 
enrollment 
Select Create a certification request and save it locally for later manual 
enrollment to have the ZyWALL generate and store a request for a certificate. 
Use the My Certificate Details screen to view the certification request and copy 
it to send to the certification authority. 
Copy the certification request from the My Certificate Details screen (see 
section 15.8) and then send it to the certification authority.
