DESCRIPTION
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.
This is the certificate's message digest that the Zyxel Device calculated using the MD5
algorithm. You can use this value to verify with the certification authority (over the phone for
example) that this is actually their certificate.
This is the certificate's message digest that the Zyxel Device calculated using the SHA1
algorithm. You can use this value to verify with the certification authority (over the phone for
example) that this is actually their certificate.
This read-only text box displays the certificate or certification request in Privacy Enhanced
Mail (PEM) format. PEM uses lowercase letters, uppercase letters and numerals to convert a
binary certificate into a printable form.
You can copy and paste the certificate into an e-mail to send to friends or colleagues or
you can copy and paste the certificate into a text editor and save the file on a
management computer for later distribution (via floppy disk for example).
Click this button and then Save in the File Download screen. The Save As screen opens,
browse to the location that you want to use and click Save.
