Struct rcrypto::Keccak

pub struct Keccak { /* fields omitted */ }

Implementations

impl Keccak

pub fn new(b: usize, nr: u32) -> Result<Keccak, CryptoError>

KECCAK-p[b,nr]
b means that the width of the permutation;
nr means that the number of rounds;

pub fn keccak_25(nr: u32) -> Self

pub fn keccak_50(nr: u32) -> Self

pub fn keccak_100(nr: u32) -> Self

pub fn keccak_200(nr: u32) -> Self

pub fn keccak_400(nr: u32) -> Self

pub fn keccak_800(nr: u32) -> Self

pub fn keccak_1600(nr: u32) -> Self

pub fn widths(&self) -> usize

the permutation widths

pub fn permutation(
    &mut self,
    byte_data: &[u8],
    results: &mut Vec<u8>
) -> Result<usize, CryptoError>

perform the KECCAK-p[b,nr] permutation, the byte_data.len() must be greater than or equal to (self.widths() + 7) / 8. The extra bits will be discarded when the byte_data.len() greater than the (self.widths() + 7) / 8, the bits processed from left to right in writing order and return the bit lengths of the results if success.;

pub fn sponge(&self, rate: usize) -> Result<KeccakSponge, CryptoError>

Sponge[Keccak-p[b,nr], pad10*1, rate]
rate must be a positive integer and strictly less than the width self.widths().

Trait Implementations

impl Clone for Keccak

fn clone(&self) -> Keccak

Returns a copy of the value.

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

Performs copy-assignment from source.
