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 NWA check incoming certificates
that are issued by this certification authority against a Certificate
Revocation List (CRL).
Clear this check box to have the NWA 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 NWA 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expired or been revoked.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 ras-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.
