DESCRIPTION
This field displays the identifying name of this certificate. You can use up to 31
alphanumeric and ;'~!@#$%^&()_+[]{}',.=- characters.
This field displays for a certificate, not a certification request.
Click the Refresh button to have this read-only text box display the hierarchy of
certification authorities that validate the certificate (and the certificate itself).
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 certificate itself). If the certificate is a self-signed certificate, the certificate itself is
the only one in the list. The NWA does not trust the 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trusted" in this field if any certificate on the path has expired or been revoked.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 or generated by the NWA.
This field displays information that identifies the owner of the certificate, such as
Common Name (CN), Organizational Unit (OU), Organization (O), State (ST), 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 as the Subject Name field.
"none" displays for a certification request.
This field displays the type of algorithm that was used to sign the certificate. The NWA
uses rsa-pkcs1-sha1 (RSA public-private key encryption algorithm and the SHA1 hash
algorithm). Some 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. "none" displays for a
certification request.
This field displays the date that the certificate expires. The text displays in red and
includes an Expired! message if the certificate has expired. "none" displays for a
certification request.
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 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
Constraint=1" means that there can only be one certification authority in the
certificate's path. This field does not display for a certification request.
