Struct AsconCxof128 

pub struct AsconCxof128 { /* private fields */ }

Ascon-CXOF128 customizable extensible-output function (NIST SP 800-232 §5.3).

Extends Ascon-XOF128 with a customization string Z (up to 256 bytes). The customization is absorbed before the message, so new_with_customization(b"") produces different output than AsconXof128 on the same input.

Implements the Xof trait.

Panics

Panics if the customization string exceeds 256 bytes.

Incremental API

use crypto::{ascon::AsconCxof128, Xof};

let mut cxof = AsconCxof128::new_with_customization(b"my-app-v1");
cxof.absorb(b"hello world");
let mut out = [0u8; 32];
cxof.squeeze(&mut out);

Implementations

impl AsconCxof128

pub fn new() -> Self

Creates a new Ascon-CXOF128 with an empty customization string.

pub fn new_with_customization(z: &[u8]) -> Self

Creates a new Ascon-CXOF128 with the given customization string.

Panics

Panics if z.len() > 256.

Trait Implementations

impl Clone for AsconCxof128

fn clone(&self) -> AsconCxof128

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Drop for AsconCxof128

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 AsconCxof128

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

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

impl Zeroize for AsconCxof128

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.
