Key Algorithm

This field displays the type of algorithm that was used to generate the

the key set in bits (1024 bits for example).

 

 

 

 

Subject

This field displays the certificate owner‘s IP address (IP), domain

 

Alternative Name

name (DNS) or e-mail address (EMAIL).

 

 

 

 

Key Usage

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.

 

 

 

 

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 NWA calculated using

 

 

the MD5 algorithm.

 

 

 

 

SHA1 Fingerprint

This is the certificate’s message digest that the NWA calculated using

 

 

the SHA1 algorithm.

 

 

 

 

Certificate in PEM

This read-only text box displays the certificate or certification request

 

(Base-64)

in Privacy Enhanced Mail (PEM) format. PEM uses 64 ASCII characters

 

Encoded Format

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).

Apply

Click Apply to save your changes. You can only change the name,
