Struct tiny_keccak::TupleHash

pub struct TupleHash { /* fields omitted */ }

The TupleHash hash functions defined in SP800-185.

TupleHash is designed to provide a generic, misuse-resistant way to combine a sequence of strings for hashing such that, for example, a TupleHash computed on the tuple ("abc" ,"d") will produce a different hash value than a TupleHash computed on the tuple ("ab","cd"), even though all the remaining input parameters are kept the same, and the two resulting concatenated strings, without string encoding, are identical.

Methods

impl TupleHash

pub fn v128(custom_string: &[u8]) -> TupleHash

Creates new TupleHash hasher with a security level of 128 bits.

pub fn v256(custom_string: &[u8]) -> TupleHash

Creates new TupleHash hasher with a security level of 256 bits.

Trait Implementations

impl Hasher for TupleHash

fn update(&mut self, input: &[u8])

Absorb additional input. Can be called multiple times.

fn finalize(self, output: &mut [u8])

Pad and squeeze the state to the output.

impl IntoXof for TupleHash

type Xof = TupleHashXof

A type implementing [Xof], eXtendable-output function interface.

fn into_xof(self) -> TupleHashXof

A method used to convert type into [Xof].

impl Clone for TupleHash

fn clone(&self) -> TupleHash

Returns a copy of the value.

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

Performs copy-assignment from source.
