276 Chapter 14 Certificates

NN47923-500

Issuer This field displays identifying information about the certification

authority that issued the certificate, such as Common Name,

Organizational Unit, Organization or Country.

With self-signed certificates, this is the same as the Subject Name

field.

Signature

Algorithm

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

certificate. The Business Secure Router uses rsa-pkcs1-sha1 (RSA

public-private key encryption algorithm and the SHA1 hash algorithm).

Some certification authorities can 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

key pair (the Business Secure Router uses RSA encryption) of the

certificate and the length of the key set in bits (1 024 bits for example).

Subject

Alternative Name

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

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

Key Usage This field displays for what functions the key of the certificate 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

certificate and “Path Length Constraint=1” means that there can only

be one certification authority in the certification path of the certificate.

MD5 Fingerprint This is the message digest of the certificate that the Business Secure

Router calculated using the MD5 algorithm.

SHA1 Fingerprint This is the message digest of the certificate that the Business Secure

Router calculated using the SHA1 algorithm.
