DESCRIPTION
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 NWA 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
there can only be one certification authority in the certificate's path.
This field displays how many directory servers with Lists of revoked
certificates the issuing certification authority of this certificate makes
available. This field also displays the domain names or IP addresses of
the servers.
This is the certificate's message digest that the NWA calculated using
the MD5 algorithm. You cannot use this value to verify that this is the
remote host's actual certificate because the NWA has signed the
certificate; thus causing this value to be different from that of the
remote host's actual certificate. See
how to verify a remote host's certificate before you import it into the
NWA.
This is the certificate's message digest that the NWA calculated using
the SHA1 algorithm. You cannot use this value to verify that this is
the remote host's actual certificate because the NWA has signed the
certificate; thus causing this value to be different from that of the
remote host's actual certificate. See
how to verify a remote host's certificate before you import it into the
NWA.
This read-only text box displays the certificate or certification request
in Privacy Enhanced Mail (PEM) format. PEM uses 64 ASCII characters
to convert the 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.
Click Apply to save your changes. You can only change the name
and/or set whether or not you want the NWA to check the CRL that
the certification authority issues before trusting a certificate issued by
the certification authority.
