Convenience 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.

Object Safety

This trait is not object safe.
