Struct tiny_keccak::Kmac

pub struct Kmac { /* fields omitted */ }

The KMAC pseudo-random functions defined in SP800-185.

The KECCAK Message Authentication Code (KMAC) algorithm is a PRF and keyed hash function based on KECCAK. It provides variable-length output, and unlike SHAKE and cSHAKE, altering the requested output length generates a new, unrelated output. KMAC has two variants, KMAC128 and KMAC256, built from cSHAKE128 and cSHAKE256, respectively. The two variants differ somewhat in their technical security properties.

Methods

impl Kmac

pub fn v128(key: &[u8], custom_string: &[u8]) -> Kmac

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

pub fn v256(key: &[u8], custom_string: &[u8]) -> Kmac

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

Trait Implementations

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

Pad and squeeze the state to the output.

impl IntoXof for Kmac

type Xof = KmacXof

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

fn into_xof(self) -> Self::Xof

A method used to convert type into [Xof].

impl Clone for Kmac

fn clone(&self) -> Kmac

Returns a copy of the value.

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

Performs copy-assignment from source.
