Struct HmacStream 

pub struct HmacStream<const OUTLEN: usize, const BLOCK: usize, D>
where
    D: DigestIncremental<OUTLEN>,
    D::IncrementalState: InitializeDigestState,
{ /* private fields */ }

Generic streaming HMAC state, parametrized by output length, block size, and an incremental digest implementation D.

Use the type aliases HmacSha256, HmacSha384, or HmacSha512 rather than spelling out the type parameters directly.

Trait Implementations

impl<const OUTLEN: usize, const BLOCK: usize, Digest> HmacState<OUTLEN> for HmacStream<OUTLEN, BLOCK, Digest>

where Digest: DigestIncremental<OUTLEN>, Digest::IncrementalState: InitializeDigestState,

fn new(key: &[u8]) -> Result<Self, Error>

Initialize a new streaming HMAC computation with the given key.

fn update(&mut self, data: &[u8]) -> Result<(), Error>

Feed a data fragment into the HMAC computation.

fn finalize(self, dst: &mut [u8; OUTLEN])

Finalize the HMAC and write the tag into dst.
