ldns(3) FreeBSD Library Functions Manual ldns(3) NAME ldns_dane_create_tlsa_rr, ldns_dane_create_tlsa_owner, ldns_dane_cert2rdf, ldns_dane_select_certificate - TLSA RR creation functions SYNOPSIS #include <stdint.h> #include <stdbool.h> #include <ldns/ldns.h> ldns_status ldns_dane_create_tlsa_rr(ldns_rr** tlsa, ldns_tlsa_certificate_usage certificate_usage, ldns_tlsa_selector selector, ldns_tlsa_matching_type matching_type, X509* cert); ldns_status ldns_dane_create_tlsa_owner(ldns_rdf** tlsa_owner, const ldns_rdf* name, uint16_t port, ldns_dane_transport transport); ldns_status ldns_dane_cert2rdf(ldns_rdf** rdf, X509* cert, ldns_tlsa_selector selector, ldns_tlsa_matching_type matching_type); ldns_status ldns_dane_select_certificate(X509** selected_cert, X509* cert, STACK_OF(X509)* extra_certs, X509_STORE* pkix_validation_store, ldns_tlsa_certificate_usage cert_usage, int index); DESCRIPTION ldns_dane_create_tlsa_rr() Creates a TLSA resource record from the certificate. No PKIX validation is performed! The given certificate is used as data regardless the value of certificate_usage. tlsa: The created TLSA resource record. certificate_usage: The value for the Certificate Usage field selector: The value for the Selector field matching_type: The value for the Matching Type field cert: The certificate which data will be represented Returns LDNS_STATUS_OK on success or an error code otherwise. ldns_dane_create_tlsa_owner() Creates a dname consisting of the given name, prefixed by the service port and type of transport: _port._transport.name. tlsa_owner: The created dname. name: The dname that should be prefixed. port: The service port number for which the name should be created. transport: The transport for which the name should be created. Returns LDNS_STATUS_OK on success or an error code otherwise. ldns_dane_cert2rdf() Creates a LDNS_RDF_TYPE_HEX type rdf based on the binary data chosen by the selector and encoded using matching_type. rdf: The created created rdf of type LDNS_RDF_TYPE_HEX. cert: The certificate from which the data is selected cert_usage and index. selected_cert: The selected cert. cert: The certificate to validate (or not) extra_certs: Intermediate certificates that might be necessary during validation. May be NULL, except when the certificate usage is "Trust Anchor Assertion" because the trust anchor has to be provided.(otherwise choose a "Domain issued certificate!" pkix_validation_store: Used when the certificate usage is "CA constraint" or "Service Certificate Constraint" to validate the certificate and, in case of "CA constraint", select the CA. When pkix_validation_store is NULL, validation is explicitly turned off and the behaviour is then the same as for "Trust anchor assertion" and "Domain issued certificate" respectively. cert_usage: Which certificate to use and how to validate. index: Used to select the trust anchor when certificate usage is "Trust Anchor Assertion". 0 is the last certificate in the validation chain. 1 the one but last, etc. When index is -1, the last certificate is used that MUST be self-signed. This can help to make sure that the intended (self signed) trust anchor is actually present in extra_certs (which is a DANE requirement). Returns LDNS_STATUS_OK on success or an error code otherwise.
