Types

type Elt

type Elt = uint16

Elt is a field element of characteristic 2 modulo z^12 + z^3 + 1

func Add

func Add(a, b Elt) Elt

Add two Elt elements together. Since an addition in Elt(2) is the same as XOR, this implementation uses a simple XOR for addition.

func Div

func Div(a, b Elt) Elt

Div calculates a / b

func Inv

func Inv(a Elt) Elt

Inv calculates the multiplicative inverse of Elt element a

func Mul

func Mul(a, b Elt) Elt

Mul calculate the product of two Elt elements.
