Function dumb_crypto::salsa20::salsa20

pub fn salsa20(input: &[u8], rounds: usize, output: &mut [u8])

Mix input using rounds of internal transformations.

NOTE: input and output lengths must be multiples of BLOCK_SIZE NOTE: output MUST have the same size as input.

Usage:

extern crate dumb_crypto;

use::dumb_crypto::salsa20::salsa20;

let mut out: [u8; 64] = [0; 64];

salsa20(&[7; 64], 100, &mut out);

assert_eq!(out.to_vec(), vec![
