Struct CShake256 

pub struct CShake256 { /* private fields */ }

cSHAKE256 (customizable SHAKE256) as defined in SP 800-185.

Allows domain separation via a function name and customization string. When both parameters are empty, CShake256 behaves identically to Shake256.

Implements the Xof trait.

One-shot API

use crypto::sha3::CShake256;

let mut output = [0u8; 64];
CShake256::hash(b"message", b"FUNCTION", b"customization", &mut output);

Incremental API

use crypto::{sha3::CShake256, Xof};

let mut cshake = CShake256::new(b"FUNCTION", b"customization");
cshake.absorb(b"hello ");
cshake.absorb(b"world");
let mut out = [0u8; 64];
cshake.squeeze(&mut out);

Implementations

impl CShake256

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

pub fn new(function_name: &[u8], customization: &[u8]) -> Self

Trait Implementations

impl Clone for CShake256

fn clone(&self) -> CShake256

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Drop for CShake256

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 Xof for CShake256

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

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

impl Zeroize for CShake256

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.
