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 ISG50 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has expired or been revoked.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 ISG50.
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 ISG50 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 ISG50 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).
