* {@link http://web.archive.org/web/19961027104704/http://www3.netscape.com/eng/security/cert-exts.html Netscape Certificate Extensions}.
*
* Note that loading an X.509 certificate and resaving it may invalidate the signature. The reason being that the signature is based on a
* portion of the certificate that contains optional parameters with default values. ie. if the parameter isn't there the default value is
* used. Problem is, if the parameter is there and it just so happens to have the default value there are two ways that that parameter can
* be encoded. It can be encoded explicitly or left out all together. This would effect the signature value and thus may invalidate the
* the certificate all together unless the certificate is re-signed.
