ZyWALL 2 Plus User's Guide
DESCRIPTION
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.
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.
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.
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 15.6 on page 279) and then send it to the certification authority.
Select Create a certification request and enroll for a certificate
immediately online to have the ZyWALL 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.
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.
Enter the IP address (or URL) of the certification authority server.
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 ZyWALL's list of certificates of trusted
certification authorities.
When you select Create a certification request and enroll for a certificate
immediately online, the certification authority may want you to include a
reference number and key to identify you when you send a certification
request. Fill in both the Reference Number and the Key fields if your
certification authority uses CMP enrollment protocol. Just fill in the Key field if
your certification authority uses the SCEP enrollment protocol.
Type the key that the certification authority gave you.
Click Apply to begin certificate or certification request generation.
Click Cancel to quit and return to the My Certificates screen.
