Struct Blake2b 

pub struct Blake2b { /* private fields */ }

BLAKE2b hasher (RFC 7693). Default: 64-byte output, 128-byte blocks.

Not FIPS-approved. Used by Argon2, libsodium, WireGuard.

Implementations

impl Blake2b

pub fn with_output_len(out_len: usize) -> Self

Create a BLAKE2b hasher with a custom output length (1..=64 bytes).

Trait Implementations

impl Clone for Blake2b

fn clone(&self) -> Blake2b

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hasher for Blake2b

const OUTPUT_LEN: usize = 64

Output size in bytes.

const BLOCK_LEN: usize = 128

Block size in bytes (for HMAC computation).

fn new() -> Self

Create a new hasher instance.

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

Feed data into the hasher (can be called multiple times).

fn finalize(self) -> Vec<u8>

Finalize and return the digest. Consumes the hasher.

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

Finalize into a caller-provided buffer (no allocation).

fn hash(data: &[u8]) -> Vec<u8>

where Self: Sized,

One-shot: hash data and return the digest.
