// SIG(0)
//
// From RFC 2931:
//
// SIG(0) provides protection for DNS transactions and requests ....
// ... protection for glue records, DNS requests, protection for message headers
// on requests and responses, and protection of the overall integrity of a response.
//
// It works like TSIG, except that SIG(0) uses public key cryptography, instead of the shared
// secret approach in TSIG.
// Supported algorithms: DSA, ECDSAP256SHA256, ECDSAP384SHA384, RSASHA1, RSASHA256 and
// RSASHA512.
//
// Signing subsequent messages in multi-message sessions is not implemented.
//
