====

A Mojo implementation of [SipHash-2-4](https://131002.net/siphash/),

a fast short-input

[PRF](https://en.wikipedia.org/wiki/Pseudorandom_function) with a

128-bit key and 64-bit output.

Extract from the description:

    SipHash is a family of pseudorandom functions (a.k.a. keyed hash

    functions) optimized for speed on short messages.

    Target applications include network traffic authentication and defense

    against hash-flooding DoS attacks.

    SipHash is secure, fast, and simple (for real):

    * SipHash is simpler and faster than previous cryptographic algorithms

      (e.g. MACs based on universal hashing)

    * SipHash is competitive in performance with insecure

      non-cryptographic algorithms (e.g. MurmurHash)

    * We propose that hash tables switch to SipHash as a hash

      function. Users of SipHash already include OpenDNS, Perl 5, Ruby, or

      Rust.

```mojo

from mojosiphash import siphash

fn main():

    let key = String("0123456789ABCDEF")

    let s = String("a")

    var sip = siphash.SipHash_2_4(key, s)

    let res: UInt64 = sip.hash()

    print(res) # 12398370950267227270

```
