Struct SSHFP

pub struct SSHFP { /* private fields */ }

RFC 4255

3.1.  The SSHFP RDATA Format

   The RDATA for a SSHFP RR consists of an algorithm number, fingerprint
   type and the fingerprint of the public host key.

3.1.3.  Fingerprint

   The fingerprint is calculated over the public key blob as described
   in [7].

   The message-digest algorithm is presumed to produce an opaque octet
   string output, which is placed as-is in the RDATA fingerprint field.

Implementations

impl SSHFP

pub fn new( algorithm: Algorithm, fingerprint_type: FingerprintType, fingerprint: Vec<u8>, ) -> SSHFP

Creates a new SSHFP record data.

Arguments

• algorithm - the SSH public key algorithm.
• fingerprint_type - the fingerprint type to use.
• fingerprint - the fingerprint of the public key.

pub fn algorithm(&self) -> Algorithm

The SSH public key algorithm.

pub fn fingerprint_type(&self) -> FingerprintType

The fingerprint type to use.

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

The fingerprint of the public key.

Trait Implementations

impl BinEncodable for SSHFP

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

Write the type to the stream

fn to_bytes(&self) -> Result<Vec<u8>, ProtoError>

Returns the object in binary form

impl Clone for SSHFP

fn clone(&self) -> SSHFP

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SSHFP

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

Formats the value using the given formatter.

impl Display for SSHFP

RFC 4255

3.2.  Presentation Format of the SSHFP RR

   The RDATA of the presentation format of the SSHFP resource record
   consists of two numbers (algorithm and fingerprint type) followed by
   the fingerprint itself, presented in hex, e.g.:

       host.example.  SSHFP 2 1 123456789abcdef67890123456789abcdef67890

   The use of mnemonics instead of numbers is not allowed.

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

Formats the value using the given formatter.

impl Hash for SSHFP

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

where __H: Hasher,

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 SSHFP

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl RecordData for SSHFP

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

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

fn record_type(&self) -> RecordType

Get the associated RecordType for the RecordData

fn into_rdata(self) -> RData

Converts this RecordData into generic RecordData

fn is_update(&self) -> bool

RDLENGTH = 0
