DESCRIPTION
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 WiMAX Device 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trusted" in this field if any certificate on the path has expired or been
revoked.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.
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 WiMAX Device.
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 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 WiMAX Device 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 WiMAX Device 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).
