Functions

func BytesSplit

func BytesSplit(buf []byte, size int) [][]byte

split bytes with n length

func BytesToString

func BytesToString(buf []byte) string

bytes to string

func GfnDouble

func GfnDouble(input []byte) []byte

GfnDouble computes 2 * input in the field of 2^n elements. The irreducible polynomial in the finite field for n=128 is x^128 + x^7 + x^2 + x + 1 (equals 0x87) Constant-time execution in order to avoid side-channel attacks

func RightXor

func RightXor(X, Y []byte) []byte

RightXor XORs smaller input (assumed Y) at the right of the larger input (assumed X)

func ShiftBytesLeft

func ShiftBytesLeft(x []byte) []byte

ShiftBytesLeft outputs the byte array corresponding to x << 1 in binary.

func ShiftBytesLeftN

func ShiftBytesLeftN(dst, x []byte, n int)

ShiftBytesLeftN puts in dst the byte array corresponding to x << n in binary.

func StringToBytes

func StringToBytes(str string) []byte

string to bytes

func XorBytes

func XorBytes(Z, X, Y []byte)

XorBytes assumes equal input length, puts X XOR Y into Z

func XorBytesMut

func XorBytesMut(X, Y []byte)

XorBytesMut assumes equal input length, replaces X with X XOR Y
