DESCRIPTION
This field displays the identifying name of this certificate. If you want to change
the name, type up to 31 characters to identify this key certificate. You may use
any character (not including spaces).
Select this check box to have the ZyXEL Device check incoming certificates that
are issued by this certification authority against a Certificate Revocation List
(CRL).
Clear this check box to have the ZyXEL Device not check incoming certificates
that are issued by this certification authority against a Certificate Revocation List
(CRL).
Click the Refresh button to have this read-only text box display the end entity's
certificate and a list of certification authority certificates that shows the hierarchy
of certification authorities that validate the end entity's certificate. 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 end
entity's own certificate). The ZyXEL Device does not trust the end entity's
certificate and displays "Not trusted" in this field if any certificate on the path has
expired or been revoked.
Click Refresh to display the certification path.
These read-only fields display detailed information about the certificate.
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.
This field displays the X.509 version number.
This field displays the certificate's identification number given by the certification
authority.
This field displays information that identifies the owner of the certificate, such as
Common Name (CN), Organizational Unit (OU), Organization (O) and Country
(C).
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 information as in the Subject
Name field.
This field displays the type of algorithm that was used to sign the certificate.
Some certification authorities use rsa-pkcs1-sha1 (RSA public-private key
encryption algorithm and the SHA1 hash algorithm). Other certification
authorities may use rsa-pkcs1-md5 (RSA public-private key encryption
algorithm and the MD5 hash algorithm).
This field displays the date that the certificate becomes applicable. The text
displays in red and includes a Not Yet Valid! message if the certificate has not
yet become applicable.
This field displays the date that the certificate expires. The text displays in red
and includes an Expiring! or Expired! message if the certificate is about to expire
or has already expired.
This field displays the type of algorithm that was used to generate the
certificate's key pair (the ZyXEL Device uses RSA encryption) and the length of
the key set in bits (1024 bits for example).
