Certification Path 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 Modem does not trust the certificate and displays
“Not trusted” in this field if any certificate on the path has expired or
been revoked.
Refresh Click Refresh to display the certification path.
Certification Information
Type
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.
Version This field displays the X.509 version number. “
Serial Number This field displays the certificate’s identification number given by the
certification authority or generated by the WiMAX Modem.
Subject This field displays information that identifies the owner of the
certificate, such as Common Name (CN), Organizational Unit (OU),
Organization (O) and Country (C).
Issuer 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.
Signature
Algorithm This field displays the type of algorithm that was used to sign the
certificate. The WiMAX Modem 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).
Valid From This field displays the date that the certificate becomes applicable.
“none” displays for a certification request.
Valid To 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.
Key Algorithm This field displays the type of algorithm that was used to generate the
certificate’s key pair (the WiMAX Modem uses RSA encryption) and
the length of the key set in bits (1024 bits for example).
Subject
Alternative Name This field displays the certificate owner‘s IP address (IP), domain
name (DNS) or e-mail address (EMAIL).
