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.
