The Mac trait defines methods for a Message Authentication algorithm.

Associated Types

type OutputSize: ArrayLength<u8>

Required methods

fn update(&mut self, data: &[u8])

Update MAC state with the given data.

fn reset(&mut self)

Reset Mac instance.

fn finalize(self) -> Output<Self>

Obtain the result of a Mac computation as a Output and consume Mac instance.

Provided methods

fn finalize_reset(&mut self) -> Output<Self>

Obtain the result of a Mac computation as a Output and reset Mac instance.

fn verify(self, tag: &[u8]) -> Result<(), MacError>

Check if tag/code value is correct for the processed input.
