ldns_pkt_tsig_verify() verifies the tsig rr for the given packet and key.  The wire  must  be  given  too
              because tsig does not sign normalized packets.
              pkt: the packet to verify
              wire: needed to verify the mac
              wire_size: size of wire
              key_name: the name of the shared key
              key_data: the key in base 64 format
              mac: original mac
              Returns true if tsig is correct, false if not, or if tsig is not set

       ldns_pkt_tsig_sign() creates a tsig rr for the given packet and key.
              pkt: the packet to sign
              key_name: the name of the shared key
              key_data: the key in base 64 format
              fudge: seconds of error permitted in time signed
              algorithm_name: the name of the algorithm used
              query_mac:  is  added  to  the digest if not NULL (so NULL is for signing queries, not NULL is for
              signing answers)
              Returns status (OK if success)
