Functions

func CanonizeEncodeP256K

func CanonizeEncodeP256K(sig []byte) []byte

CanonizeEncodeP256K returns the canonical versions of the signature the canonical version enforce low S values if S is above order / 2 it negating the S (modulo the order (N))

func ECCoordinateFromPrivateKey

func ECCoordinateFromPrivateKey(d []byte, curveName string) (xBytes, yBytes []byte)

ECCoordinateFromPrivateKey given an elliptic curve name it will produce X and Y coordiante from D

func GetCurve

func GetCurve(name string) elliptic.Curve
