DESCRIPTION

Certificate Path

Click the Refresh button to have this read-only text box display the

 

end entity’s certificate and a list of certification authority certificates

 

that shows the hierarchy of certification authorities that validate the

 

end entity’s certificate. 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 end entity’s own

 

certificate). The NWA does not trust the end entity’s certificate and

 

displays “Not trusted” in this field if any certificate on the path has

 

expired or been revoked.

Certificate

These read-only fields display detailed information about the

Information

certificate.

 

 

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.

 

 

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 information as in the

 

Subject Name field.

 

 

Signature

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

Algorithm

certificate. Some certification authorities use rsa-pkcs1-sha1 (RSA

 

public-private key encryption algorithm and the SHA1 hash

 

algorithm). Other certification authorities may use ras-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.

 

The text displays in red and includes a Not Yet Valid! message if the

 

certificate has not yet become applicable.

 

 

Valid To

This field displays the date that the certificate expires. The text

 

displays in red and includes an Expiring! or Expired! message if the

 

certificate is about to expire or has already expired.

 

 

Key Algorithm

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

 

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

 

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

 

 

Subject

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

Alternative Name

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