dumb-crypto

This library implements following cryptographic routines in the dumbest and the most obvious way:

• sha256
• hmac-sha256
• pbkdf2-sha256
• salsa20
• scrypt

Why?

Normally, one would find a highly optimized code implementing those. However, verifying such code is a non-trivial task. All routines (except for scrypt itself) are pre-requisites for scrypt, and a provided just for convenience.

Quick example

```rust extern crate dumb_crypto;

use::dumb_crypto::scrypt::Scrypt;

let scrypt = Scrypt::new(1, 128, 1);

let mut out: [u8; 8] = [0; 8];

scrypt.derive(b"passphrase", b"salt", &mut out);

asserteq!(out.tovec(), vec![ 79, 35, 225, 99, 145, 145, 172, 245, ]); ```
