LABEL

DESCRIPTION

 

 

Key Algorithm

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

 

certificate’s key pair (the ZyAIR uses RSA encryption) and the length of the key

 

set in bits (1024 bits for example).

Subject Alternative

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

Name

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.

CRL Distribution

This field displays how many directory servers with Lists of revoked certificates

Points

the issuing certification authority of this certificate makes available. This field

 

also displays the domain names or IP addresses of the servers.

MD5 Fingerprint

This is the certificate’s message digest that the ZyAIR calculated using the MD5

 

algorithm. You can use this value to verify with the certification authority (over

 

the phone for example) that this is actually their certificate.

SHA1 Fingerprint

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

 

SHA1 algorithm. You can use this value to verify with the certification authority

 

(over the phone for example) that this is actually their certificate.

Certificate in PEM

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

(Base-64) Encoded

Enhanced Mail (PEM) format. PEM uses 64 ASCII characters to convert the

Format

binary certificate into a printable form.

 

You can copy and paste the certificate into an e-mail to send to friends or

 

colleagues or you can copy and paste the 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 back to the ZyAIR. You can only change the

 

name and/or set whether or not you want the ZyAIR to check the CRL that the

 

certification authority issues before trusting a certificate issued by the

 

certification authority.
