LABEL DESCRIPTION
Certificate 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 ZyXEL Device use this certificate to
sign the trusted remote host certificates that you import to the ZyXEL
Device. 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 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trusted” in this field if any certificate on the path has expired or been
revoked.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.
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.
Signature
Algorithm This field displays the type of algorithm that was used to sign the
certificate. The ZyXEL Device uses rsa-pkcs1-sha1 (RSA public-
private key encryption algorithm and the SHA1 hash algorithm).
Some certification authorities may use rsa-pkcs1-md5 (RSA public-
private key encryption algorithm and the MD5 hash algorithm).
