LABEL DESCRIPTION
Name This field displays the identifying name of this certificate. You can use up to 31 alphanumeric
and ;‘~!@#$%^&()_+[]{}’,.=-
characters.
Certification Path
This field displays for a certificate, not a certification request.
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 Zyxel Device 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this field if any certificate on the path has expired or been revoked.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 Zyxel Device.

Name (CN), Organizational Unit (OU), Organization (O), State (ST), and Country (C).
