 * ARM mbedTLS requires a CA certificate to be set in its configuration before it will
 * request a client certificate from peers. Since we want to do that, and not all
 * installations will have a CA certificate to hand, we have this.
 *
 * Its key was securely destroyed after being generated, but even if it wasn't, that
 * doesn't matter; the IRCd will accept ALL certificates, whether signed by this CA
 * certificate or not!
 *
 * After all, it only cares about certificates in as far as to generate a fingerprint
 * for them.
 *
 * Yes, this is a massive hack, but there is no alternative.
