Table 69 My Certificate details
Label Description
Issuer This field displays identifying information about the certificate's issuing
certification authority, such as Common Name, Organizational Unit,
Organization or Country.
With self-signed certificates, this is the same as the Subject Name
field.
Signature This field displays the type of algorithm that was used to sign the
Algorithm 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
certificate's key pair (the Business Secure Router uses RSA
encryption) and the length of the key set in bits (1 024 bits for
example).
Subject This field displays the certificate owner's IP address (IP), domain
Alternative Name 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 Business Secure
Router calculated using the MD5 algorithm.
SHA1 Fingerprint This is the certificate's message digest that the Business Secure
Router calculated using the SHA1 algorithm.
