32 ldns_dane_create_tlsa_rr() Creates a TLSA resource record from the cer‐
33 tificate. No PKIX validation is performed! The given certifi‐
34 cate is used as data regardless the value of certificate_usage.
35 tlsa: The created TLSA resource record.
37 certificate_usage: The value for the Certificate Usage field
38 selector: The value for the Selector field
39 matching_type: The value for the Matching Type field
40 cert: The certificate which data will be represented
41 Returns LDNS_STATUS_OK on success or an error code otherwise.
43 ldns_dane_create_tlsa_owner() Creates a dname consisting of the given
45 name, prefixed by the service port and type of transport: _<‐
46 EM>port</EM>._<EM>transport</EM>.<EM>name</EM>.
47 tlsa_owner: The created dname.
49 name: The dname that should be prefixed.
50 port: The service port number for which the name should be cre‐
51 ated.
52 transport: The transport for which the name should be created.
53 Returns LDNS_STATUS_OK on success or an error code otherwise.
54 ldns_dane_cert2rdf() Creates a LDNS_RDF_TYPE_HEX type rdf based on the
56 binary data chosen by the selector and encoded using match‐
57 ing_type.
58 rdf: The created created rdf of type LDNS_RDF_TYPE_HEX.
60 cert: The certificate from which the data is selected
61 selector: The full certificate or the public key
62 matching_type: The full data or the SHA256 or SHA512 hash of the
63 selected data
64 Returns LDNS_STATUS_OK on success or an error code otherwise.
65 ldns_dane_select_certificate() Selects the certificate from cert, ex‐
67 tra_certs or the pkix_validation_store based on the value of
68 cert_usage and index.
69 selected_cert: The selected cert.
71 cert: The certificate to validate (or not)
72 extra_certs: Intermediate certificates that might be necessary
73 during validation. May be NULL, except when the certificate us‐
74 age is "Trust Anchor Assertion" because the trust anchor has to
75 be provided.(otherwise choose a "Domain issued certificate!"
76 pkix_validation_store: Used when the certificate usage is "CA
77 constraint" or "Service Certificate Constraint" to validate the
78 certificate and, in case of "CA constraint", select the CA.
79 When pkix_validation_store is NULL, validation is explicitly
80 turned off and the behaviour is then the same as for "Trust an‐
81 chor assertion" and "Domain issued certificate" respectively.
82 cert_usage: Which certificate to use and how to validate.
83 index: Used to select the trust anchor when certificate usage is
84 "Trust Anchor Assertion". 0 is the last certificate in the vali‐
85 dation chain. 1 the one but last, etc. When index is -1, the
86 last certificate is used that MUST be self-signed. This can
87 help to make sure that the intended (self signed) trust anchor
88 is actually present in extra_certs (which is a DANE require‐
89 ment).
90 Returns LDNS_STATUS_OK on success or an error code otherwise.
