Struct Keccak256 

pub struct Keccak256 { /* private fields */ }

Keccak-256 hasher state for incremental hashing.

This struct wraps tiny-keccak’s Keccak hasher for Keccak-256.

Implementations

impl Keccak256

pub fn new() -> Self

Creates a new Keccak-256 hasher.

Absorbs input data into the sponge state.

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

Finalizes the hash computation and writes the result to the output buffer.

Panics
