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

Algorithm

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

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

public-private key encryption algorithm and the SHA1 hash

algorithm). Other 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.

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 NWA3000-N series AP uses RSA encryption)

and the length of the key set in bits (1024 bits for example).

Subject

Alternative Name

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

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 NWA3000-N series AP

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.
