Struct Keccak256

pub struct Keccak256 { /* private fields */ }

Simple Keccak-256 hasher.

Note that the “native-keccak” feature is not supported for this struct, and will default to the tiny_keccak implementation.

Implementations

impl Keccak256

pub fn new() -> Self

Creates a new Keccak256 hasher.

pub fn update(&mut self, bytes: impl AsRef<[u8]>)

Absorbs additional input. Can be called multiple times.

pub fn finalize(self) -> B256

Pad and squeeze the state.

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

Pad and squeeze the state into output.

Panics

Panics if output is not 32 bytes long.

pub fn finalize_into_array(self, output: &mut [u8; 32])

Pad and squeeze the state into output.

pub unsafe fn finalize_into_raw(self, output: *mut u8)

Pad and squeeze the state into output.

Safety

output must point to a buffer that is at least 32-bytes long.
