Struct ascon_core::State

pub struct State { /* private fields */ }

The state of Ascon’s permutation.

The permutation operates on a state of 320 bits represented as 5 64 bit words.

Implementations

impl State

pub fn new(x0: u64, x1: u64, x2: u64, x3: u64, x4: u64) -> State

Instantiate new state from the given values.

pub fn permute_12(&mut self)

Perform permutation with 12 rounds.

pub fn permute_8(&mut self)

Perform permutation with 8 rounds.

pub fn permute_6(&mut self)

Perform permutation with 6 rounds.

pub fn permute_1(&mut self)

Perform permutation with 1 round

pub fn permute_n(&mut self, rounds: usize)

Perform a given number (up to 12) of permutations

Panics (in debug mode) if rounds is larger than 12.

pub fn as_bytes(&self) -> [u8; 40]

Convert state to bytes.

Trait Implementations

impl AsRef<[u64]> for State

fn as_ref(&self) -> &[u64]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for State

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for State

fn default() -> State

Returns the “default value” for a type.

impl From<&[u64; 5]> for State

fn from(value: &[u64; 5]) -> State
