/**
 * Implemenation of ICertificate.
 *
 * This implemenation is a very thin wrapper around an immutable
 * RTCRX509CERTIFICATE and a few caller stated views.
 *
 * The views are whether the caller thinks the certificate is trustworthly, and
 * whether the caller thinks it's expired or not.  The caller could be sitting
 * on more information, like timestamp and intermediate certificates, that helps
 * inform the caller's view on these two topics.
 *
 * @remarks It could be helpful to let the caller also add certificate paths
 *          showing how this certificate ends up being trusted.  However, that's
 *          possibly quite some work and will have to wait till required...
