Go implementation of SipHash-2-4, a fast short-input PRF created by
Jean-Philippe Aumasson and Daniel J. Bernstein (http://131002.net/siphash/).

INSTALLATION

    $ go get github.com/dchest/siphash

USAGE

    import "github.com/dchest/siphash"

There are two ways to use this package.
The slower one is to use the standard hash.Hash64 interface:

    h := siphash.New(key)
    h.Write([]byte("Hello"))
    sum := h.Sum(nil) // returns 8-byte []byte

or

    sum64 := h.Sum64() // returns uint64

The faster one is to use Hash() function, which takes two uint64 parts of
16-byte key and a byte slice, and returns uint64 hash:

    sum64 := siphash.Hash(key0, key1, []byte("Hello"))

The keys and output are little-endian.

FUNCTIONS

func Hash(k0, k1 uint64, p []byte) uint64

    Hash returns the 64-bit SipHash-2-4 of the given byte slice with two
    64-bit parts of 128-bit key: k0 and k1.

func New(key []byte) hash.Hash64

    New returns a new hash.Hash64 computing SipHash-2-4 with 16-byte key.
