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