Typedef Documentation

§ ldns_dnssec_data_chain

Chain structure that contains all DNSSEC data needed to verify an rrset.

Definition at line 19 of file dnssec_verify.h.

§ ldns_dnssec_trust_tree

Tree structure that contains the relation of DNSSEC data, and their cryptographic status.

This tree is derived from a data_chain, and can be used to look whether there is a connection between an RRSET and a trusted key. The tree only contains pointers to the data_chain, and therefore one should never free() the data_chain when there is still a trust tree derived from that chain.

Example tree: key key key \ | / \ | / \ | / ds | key | key | rr

For each signature there is a parent; if the parent pointer is null, it couldn't be found and there was no denial; otherwise is a tree which contains either a DNSKEY, a DS, or a NSEC rr
