Trait Implementations

impl Clone for Sha256

fn clone(&self) -> Sha256

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Digest for Sha256

const OUTPUT_LEN: usize = 32

The digest length in octets.

const BLOCK_LEN: usize = 64

The internal block size in octets — the rate for the Merkle–Damgård / sponge construction. Needed by keyed constructions such as HMAC.

fn new() -> Sha256

Create a fresh hasher.

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

Absorb a chunk of input. May be called repeatedly.

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

Consume the hasher and write the digest into out.

fn digest(data: &[u8], out: &mut [u8])

One-shot convenience: update(data) then finalize(out).
