Struct Shake256 

pub struct Shake256 { /* private fields */ }

SHAKE256 extensible-output function (XOF) as defined in FIPS 202.

Implements both the Xof and Hasher traits.

One-shot API

use crypto::sha3::Shake256;

let mut output = [0u8; 64];
Shake256::hash(b"hello world", &mut output);

Incremental XOF API

use crypto::{sha3::Shake256, Xof};

let mut shake = Shake256::new();
shake.absorb(b"hello ");
shake.absorb(b"world");
let mut out = [0u8; 64];
shake.squeeze(&mut out);

Implementations

impl Shake256

pub fn hash(data: &[u8], output: &mut [u8])

pub fn new() -> Self

Trait Implementations

impl Clone for Shake256

fn clone(&self) -> Shake256

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Drop for Shake256

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Hasher for Shake256

const BLOCK_SIZE: usize = SHAKE256_RATE

The internal block size of the hash function

const OUTPUT_SIZE: usize = 64

The output size of the hash function

fn new() -> Self

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

fn sum(self) -> Hash

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

impl Xof for Shake256

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

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

impl Zeroize for Shake256

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
