Struct Kt256 

pub struct Kt256<'cs> { /* private fields */ }

KT256 hasher.

Implementations

impl<'cs> Kt256<'cs>

pub fn new(customization: &'cs [u8]) -> Kt256<'cs>

Creates a new KT256 instance with the given customization string.

Trait Implementations

impl AlgorithmName for Kt256<'_>

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

Write algorithm name into f.

impl BlockSizeUser for Kt256<'_>

type BlockSize = UInt<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>, B0>

Size of the block in bytes.

fn block_size() -> usize

Return block size in bytes.

impl<'cs> Clone for Kt256<'cs>

fn clone(&self) -> Kt256<'cs>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CollisionResistance for Kt256<'_>

256-bit collision resistance per RFC 9861 §7.8, conditional on output length: this figure applies at an output of at least 2 * CollisionResistance = 64 bytes, per the digest::CollisionResistance trait contract. Kt256 is a XOF with no fixed output size, so that length is the caller’s choice: at a shorter output, the same contract gives min(CollisionResistance, OutputSize / 2) bytes — e.g. 128-bit, not 256-bit, at the 32-byte output used in this crate’s examples.

type CollisionResistance = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>

Collision resistance in bytes.

impl Debug for Kt256<'_>

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

Formats the value using the given formatter.

impl<'cs> Default for Kt256<'cs>

fn default() -> Kt256<'cs>

Returns the “default value” for a type.

impl ExtendableOutput for Kt256<'_>

type Reader = Kt256Reader

Reader

fn finalize_xof(self) -> <Kt256<'_> as ExtendableOutput>::Reader

Retrieve XOF reader and consume hasher instance.

fn finalize_xof_into(self, out: &mut [u8])

Finalize XOF and write result into out.

fn digest_xof(input: impl AsRef<[u8]>, output: &mut [u8])

where Self: Default,

Compute hash of data and write it into output.

fn finalize_boxed(self, output_size: usize) -> Box<[u8]>

Retrieve result into a boxed slice of the specified size and consume the hasher.

impl HashMarker for Kt256<'_>

impl Reset for Kt256<'_>

fn reset(&mut self)

fn chain(self, data: impl AsRef<[u8]>) -> Self

where Self: Sized,
