keccakrs 0.1.6

Add to Cargo.toml

[dependencies]
keccakrs = "*"

In your code, use as follow:

extern crate keccakrs;
use keccakrs::*;

fn main() {
  let mut keccak = keccakrs::Keccak::new(1088usize, 512usize);
  /* Other options include:
  *  keccak = keccakrs::new_keccak1600_224();
  *  keccak = keccakrs::new_keccak1600_256();
  *  keccak = keccakrs::new_keccak1600_384();
  *  keccak = keccakrs::new_keccak1600_512();
  */

  let input = &mut String::from("Hello World");
  
  keccak.injest(input);

  let output: Vec<u8> = keccak.hash();
  let state: Vec<u64> = keccak.get_internal_state();
}

This package is under development. Use at own risk.

The primary goal of this code base is to present a easy to read and understand implementation of Keccak.

(This is not a particularly fast implementation of Keccak, but it utilises NO unsafe code)
