func P256 ¶

func P256() elliptic.Curve

func Unmarshal ¶

func Unmarshal(curve elliptic.Curve, data []byte) (x, y *big.Int)

func UnmarshalCompressed ¶

func UnmarshalCompressed(curve elliptic.Curve, data []byte) (x, y *big.Int)

UnmarshalCompressed converts a point, serialized by MarshalCompressed, into an x, y pair. It is an error if the point is not in compressed form, is not on the curve, or is the point at infinity. On error, x = nil.
