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).
Click the Refresh button to have this read-only text box display the end entity's
own certificate and a list of certification authority certificates in the hierarchy of
certification authorities that validate a certificate's issuing certification authority.
For a trusted host, the list consists of the end entity's own certificate and the
default self-signed certificate that the ZyXEL Device uses to sign remote host
certificates.
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. With trusted
remote host certificates, this field always displays CA-signed. The ZyXEL
Device is the Certification Authority that signed the certificate. 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 device
that created the certificate.
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 default self-signed
certificate on the ZyXEL Device that the ZyXEL Device uses to sign the trusted
remote host certificates.
This field displays the type of algorithm that the ZyXEL Device used to sign the
certificate, which is rsa-pkcs1-sha1 (RSA public-private key encryption
algorithm and the SHA1 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).
This field displays the certificate's owner's IP address (IP), domain name
(DNS) or e-mail address (EMAIL).
This field displays for what functions the certificate's key can be used. For
example, "DigitalSignature" means that the key can be used to sign certificates
and "KeyEncipherment" means that the key can be used to encrypt text.
This field displays general information about the certificate. For example,
Subject Type=CA means that this is a certification authority's certificate and
"Path Length Constraint=1" means that there can only be one certification
authority in the certificate's path.
