Struct Keccak

pub struct Keccak { /* private fields */ }

An implementation of keccak functions. The Keccak reference.

Example

[dependencies]
keccak-rust = *

extern crate keccak_rust;
use keccak_rust::*;

const YOUR_INPUT_BYTES: [u8; 12] = [72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 33];

fn main() {
    let mut keccak = Keccak::new(SecurityLevel::SHA256, StateBitsWidth::F1600);
    keccak.append(&mut YOUR_INPUT_BYTES);
    println!("{:?}", keccak.hash());
}

Implementations

impl Keccak

pub fn new(security: SecurityLevel, width: StateBitsWidth) -> Keccak

Creates a new keccak state with a provided security level and state bits width.

Possible securities levels:

• SHA224 (224 bit)
• SHA256 (256 bit)
• SHA384 (384 bit)
• SHA512 (512 bit)

Possible state bits widths:

• f25
• f50
• f100
• f200
• f400
• f800
• f1600

pub fn append(&mut self, input: &BytesArr)

Appends input to current state

pub fn hash(&mut self) -> BytesVec

Returns keccak hash based on current state
