Struct Blake2s 

pub struct Blake2s { /* private fields */ }

BLAKE2s hasher (RFC 7693). Default: 32-byte output, 64-byte blocks.

32-bit oriented sibling of BLAKE2b. Faster on embedded (ARM Cortex-M) and 32-bit RISC-V targets. Used in WireGuard, Zcash (Equihash), and various file-integrity tools.

Implementations

impl Blake2s

pub fn with_output_len(out_len: usize) -> Self

Create a BLAKE2s hasher with a custom output length (1..=32 bytes).

Trait Implementations

impl Clone for Blake2s

fn clone(&self) -> Blake2s

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hasher for Blake2s

const OUTPUT_LEN: usize = 32

Output size in bytes.

const BLOCK_LEN: usize = 64

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.
