Struct SimpleMac

pub struct SimpleMac(/* private fields */);

Simple Message Authentication Code (MAC) computation wrapper Use new, update and finalize triplet to produce MAC of arbitrary data. Currently instantiated using Blake2s256 MAC.

Implementations

impl SimpleMac

pub fn new(key: &SecretKey) -> Self

Create new instance of the MAC using the given secret key.

Trait Implementations

impl DigestLike<Blake2sMac<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>> for SimpleMac

fn internal_state(&mut self) -> &mut Blake2sMac256

Access to the internal state of the digest-like operation.

const SIZE: usize = <T::OutputSize>::USIZE

Length of the digest in bytes

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

Update the internal state of the digest-like using the given input data.

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

Retrieve the final digest value into a prepared buffer and reset this instance so it could be reused for a new computation.

fn finalize(&mut self) -> GenericArray<u8, T::OutputSize>

Retrieve the final digest value and reset this instance so it could be reused for a new computation.
