Functions

func ByteXor

func ByteXor(a, b []byte) ([]byte, error)

ByteXor Compute the XOR of given byte arrays returns error if the bytes are not of same length

func CommonPrefixLen

func CommonPrefixLen(a, b []byte) int

CommonPrefixLen computes the Common Prefix Length of the given byte slices. It XORs them and find the leading zeroes.

func Distance

func Distance(a, b []byte) *big.Int

Distance computes the XOR dist between two byte arrays

func Hash

func Hash(src []byte) []byte

Hash sha256 's the given byte

func LogDistance

func LogDistance(a, b []byte) int

LogDistance Log dist: length - leading zero count
