Functions

func FastSum256

func FastSum256(data []byte) [32]byte

FastSum256 returns a hash sum of the input data using highwayhash. This method is not secure, but may be used as a quick identifier for objects where collisions are acceptable.

func FastSum64

func FastSum64(data []byte) uint64

FastSum64 returns a hash sum of the input data using highwayhash. This method is not secure, but may be used as a quick identifier for objects where collisions are acceptable.
