Click TOOLS > Certificates > Trusted CAs and then click Import to open the

trusted certification authority’s certificate from a computer to the WiMAX Device.
The WiMAX Device trusts any valid certificate signed by any of the imported
trusted CA certificates.

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.
Basic Constraint This field displays general information about the certificate. For
example, Subject Type=CA means that this is a certification
authority’s certificate and “Path Length Constraint=1” means that
there can only be one certification authority in the certificate’s path.

MD5 Fingerprint This is the certificate’s message digest that the WiMAX Device

Certificate in PEM
(Base-64)
Encoded Format This read-only text box displays the certificate or certification request
in Privacy Enhanced Mail (PEM) format. PEM uses lowercase letters,
uppercase letters and numerals to convert the binary certificate into a
printable form.
You can copy and paste a certification request into a certification
authority’s web page, an e-mail that you send to the certification
authority or a text editor and save the file on a management
computer for later manual enrollment.
You can copy and paste a certificate into an e-mail to send to friends
or colleagues or you can copy and paste a certificate into a text editor
and save the file on a management computer for later distribution
(via floppy disk for example).
