ldns_pkt_tsig_verify, ldns_pkt_tsig_sign - tsig signing and verification


#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);


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)
