NAME¶

ldns_pkt_tsig_verify, ldns_pkt_tsig_sign - tsig signing and verification

SYNOPSIS¶

#include <stdint.h>
#include <stdbool.h>

#include <ldns/ldns.h>

bool ldns_pkt_tsig_verify(ldns_pkt *pkt, const uint8_t *wire, size_t wire_size, const char *key_name, const char *key_data, const ldns_rdf *mac);

ldns_status ldns_pkt_tsig_sign(ldns_pkt *pkt, const char *key_name, const char *key_data, uint16_t fudge, const char *algorithm_name, const ldns_rdf *query_mac);

DESCRIPTION¶

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)
