P-660HN-F1 User’s Guide

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 ZyXEL Device 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 ZyXEL Device 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 ZyXEL Device 
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.

Enrollment Options

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 ZyXEL Device 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 ZyXEL Device 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 

) and then send it to the certification authority.

Create a certification 
request and enroll for 
a certificate 
immediately online

Select Create a certification request and enroll for a certificate 
immediately online to have the ZyXEL Device generate a request for a 
certificate and apply to a certification authority for a certificate. 
You must have the certification authority’s certificate already imported in the 
Trusted CAs screen.
When you select this option, you must select the certification authority’s 
enrollment protocol and the certification authority’s certificate from the drop-
down list boxes and enter the certification authority’s server address. You also 
need to fill in the Reference Number and Key if the certification authority 
requires them. 

Enrollment Protocol

Select the certification authority’s enrollment protocol from the drop-down list 
box.
Simple Certificate Enrollment Protocol (SCEP) is a TCP-based enrollment 
protocol that was developed by VeriSign and Cisco.
Certificate Management Protocol (CMP) is a TCP-based enrollment protocol 
that was developed by the Public Key Infrastructure X.509 working group of 
the Internet Engineering Task Force (IETF) and is specified in RFC 2510.

CA Server Address 

Enter the IP address (or URL) of the certification authority server.

CA Certificate

Select the certification authority’s certificate from the CA Certificate drop-
down list box.
You must have the certification authority’s certificate already imported in the 
Trusted CAs screen. Click Trusted CAs to go to the Trusted CAs screen 
where you can view (and manage) the ZyXEL Device's list of certificates of 
trusted certification authorities.
