Description
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.
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).
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.
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.
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).
This field displays the certificate owner's IP address (IP), domain
name (DNS) or e-mail address (EMAIL).
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.
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.
This is the message digest of the certificate that the Business Secure
Router calculated using the MD5 algorithm.
Router calculated using the SHA1 algorithm.
