}

Convinience wrapper trait covering functionality of cryptographic hash functions with fixed output size.

This trait wraps Update, FixedOutput, Default, and HashMarker traits and provides additional convenience methods.

Required Methods

fn new() -> Self

Create new hasher instance.

fn new_with_prefix(data: impl AsRef<[u8]>) -> Self

Create new hasher instance which has processed the provided data.

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

Process data, updating the internal state.

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

Process input data in a chained manner.

fn finalize(self) -> GenericArray<u8, Self::OutputSize>

Retrieve result and consume hasher instance.

fn finalize_into(self, out: &mut GenericArray<u8, Self::OutputSize>)

Write result into provided array and consume the hasher instance.

fn finalize_reset(&mut self) -> GenericArray<u8, Self::OutputSize>where
    Self: FixedOutputReset,

Retrieve result and reset hasher instance.

fn finalize_into_reset(&mut self, out: &mut GenericArray<u8, Self::OutputSize>)where
    Self: FixedOutputReset,

Write result into provided array and reset the hasher instance.

fn reset(&mut self)where
    Self: Reset,

Reset hasher instance to its initial state.

fn output_size() -> usize

Get output size of the hasher

fn digest(data: impl AsRef<[u8]>) -> GenericArray<u8, Self::OutputSize>

Compute hash of data.
