+SipHash (Go)
+============
+
+[![Build Status](https://travis-ci.org/dchest/siphash.svg)](https://travis-ci.org/dchest/siphash)
+
+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 Hash128(k0, k1 uint64, p []byte) (uint64, uint64)
+
+Hash128 returns the 128-bit SipHash-2-4 of the given byte slice with two
+64-bit parts of 128-bit key: k0 and k1.
+
+Note that 128-bit SipHash is considered experimental by SipHash authors at this time.
+
+### func New(key []byte) hash.Hash64
+
+New returns a new hash.Hash64 computing SipHash-2-4 with 16-byte key.
+
+### func New128(key []byte) hash.Hash
+
+New128 returns a new hash.Hash computing SipHash-2-4 with 16-byte key and 16-byte output.
+
+Note that 16-byte output is considered experimental by SipHash authors at this time.
