LIBRARY

DNS Resolver library (libgetdns, -lgetdns)

SYNOPSIS

#include <getdns.h>

getdns_return_t
getdns_validate_dnssec (getdns_list *record_to_validate,

getdns_list *bundle_of_support_records,
getdns_list *trust_anchor_records)

DESCRIPTION

If an application wants the API to perform DNSSEC validation without using the extensions, it can use the getdns_validate_dnssec() helper function. The API will use the resource records in bundle_of_support_records to construct the validation chain and the DNSKEY or DS records in trust_anchor_records as trust anchors. The default list of trust anchor records that is used by the library to validate DNSSEC can be retrieved by using the getdns_root_trust_anchor helper function.

record_to_validate

the resource record being validated

bundle_of_support_records

records used to construct the validation chain

trust_anchor_records

RETURN VALUES
