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: _<EM>port</EM>._<EM>transport</EM>.<‐
              EM>name</EM>.

              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
              selector: The full certificate or the public key
              matching_type: The full data or the SHA256 or SHA512 hash of the selected data
              Returns LDNS_STATUS_OK on success or an error code otherwise.

       ldns_dane_select_certificate() Selects the certificate from cert, extra_certs or the
              pkix_validation_store based on the value of 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.
