DESCRIPTION

25       ldns_pkt_tsig_verify() verifies the tsig rr for the given packet and
26              key.  The wire must be given too because tsig does not sign nor‐
27              malized packets.
28              pkt: the packet to verify
29              wire: needed to verify the mac
30              wire_size: size of wire
31              key_name: the name of the shared key
32              key_data: the key in base 64 format
33              mac: original mac
34              Returns true if tsig is correct, false if not, or if tsig is not
35              set
36
37       ldns_pkt_tsig_sign() creates a tsig rr for the given packet and key.
38              pkt: the packet to sign
39              key_name: the name of the shared key
40              key_data: the key in base 64 format
41              fudge: seconds of error permitted in time signed
42              algorithm_name: the name of the algorithm used
43              query_mac: is added to the digest if not NULL (so NULL is for
44              signing queries, not NULL is for signing answers)
45              Returns status (OK if success)
