2.1.  TLSA RDATA Wire Format

   The RDATA for a TLSA RR consists of a one-octet certificate usage
   field, a one-octet selector field, a one-octet matching type field,
   and the certificate association data field.

Implementations

impl TLSA

pub fn new( cert_usage: CertUsage, selector: Selector, matching: Matching, cert_data: Vec<u8> ) -> Self

Constructs a new TLSA

RFC 6698, DNS-Based Authentication for TLS

2.  The TLSA Resource Record

   The TLSA DNS resource record (RR) is used to associate a TLS server
   certificate or public key with the domain name where the record is
   found, thus forming a "TLSA certificate association".  The semantics
   of how the TLSA RR is interpreted are given later in this document.

   The type value for the TLSA RR type is defined in Section 7.1.

   The TLSA RR is class independent.

   The TLSA RR has no special Time to Live (TTL) requirements.

pub fn cert_usage(&self) -> CertUsage

Specifies the provided association that will be used to match the certificate presented in the TLS handshake

pub fn selector(&self) -> Selector

Specifies which part of the TLS certificate presented by the server will be matched against the association data

pub fn matching(&self) -> Matching

Specifies how the certificate association is presented

pub fn cert_data(&self) -> &[u8]

Binary data for validating the cert, see other members to understand format

Trait Implementations

impl BinEncodable for TLSA

fn emit(&self, encoder: &mut BinEncoder<'_>) -> ProtoResult<()>

Write the type to the stream

fn to_bytes(&self) -> ProtoResult<Vec<u8>>

Returns the object in binary form

impl Clone for TLSA

fn clone(&self) -> TLSA

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TLSA

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TLSA

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

2.2.  TLSA RR Presentation Format

  The presentation format of the RDATA portion (as defined in
  [RFC1035]) is as follows:

  o  The certificate usage field MUST be represented as an 8-bit
     unsigned integer.

  o  The selector field MUST be represented as an 8-bit unsigned
     integer.

  o  The matching type field MUST be represented as an 8-bit unsigned
     integer.

  o  The certificate association data field MUST be represented as a
     string of hexadecimal characters.  Whitespace is allowed within
     the string of hexadecimal characters, as described in [RFC1035].

2.3.  TLSA RR Examples

   In the following examples, the domain name is formed using the rules
   in Section 3.

   An example of a hashed (SHA-256) association of a PKIX CA
   certificate:

   _443._tcp.www.example.com. IN TLSA (
      0 0 1 d2abde240d7cd3ee6b4b28c54df034b9
            7983a1d16e8a410e4561cb106618e971 )

   An example of a hashed (SHA-512) subject public key association of a
   PKIX end entity certificate:

   _443._tcp.www.example.com. IN TLSA (
      1 1 2 92003ba34942dc74152e2f2c408d29ec
            a5a520e7f2e06bb944f4dca346baf63c
            1b177615d466f6c4b71c216a50292bd5
            8c9ebdd2f74e38fe51ffd48c43326cbc )

   An example of a full certificate association of a PKIX end entity
   certificate:

   _443._tcp.www.example.com. IN TLSA (
      3 0 0 30820307308201efa003020102020... )

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for TLSA

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TLSA

fn eq(&self, other: &TLSA) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RecordData for TLSA

fn try_from_rdata(data: RData) -> Result<Self, RData>

Attempts to convert to this RecordData from the RData type, if it is not the correct type the original is returned

fn try_borrow(data: &RData) -> Option<&Self>

fn record_type(&self) -> RecordType

Get the associated RecordType for the RecordData

fn into_rdata(self) -> RData

Converts this RecordData into generic RecordData

impl Serialize for TLSA

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
