# Usage

```
use cryptonight::byte_string;
use cryptonight::hash;
use cryptonight::hash::{MEM_SIZE, ebyte_mul};
use cryptonight::aes;
use cryptonight::aes::{AESSupport};
```

## Cryptonight White Paper
```
    let aes = aes::new(AESSupport::HW);

    let input = byte_string::string_to_u8_array("");
    
    let cn_hash = hash::hash_alloc_scratchpad(&input, &aes, hash::HashVersion::Version6);
    // "eb14e8a833fac6fe9a43b57b336789c46ffe93f2868452240720607b14387e11"

    let input2 = b"This is a test";
    let cn_hash2 = hash::hash_alloc_scratchpad(&input2[0..], &aes, hash::HashVersion::Version6);
