Properties

curve

val curve: ECCurve

the curve on which this point lies

homX

val homX: ModularBigInteger

homogeneous X coordinate of point (X : Y : Z)

homY

val homY: ModularBigInteger

homogeneous Y coordinate of point (X : Y : Z)

homZ

val homZ: ModularBigInteger

homogeneous Z coordinate of point (X : Y : Z)

isPointAtInfinity

val isPointAtInfinity: Boolean

whether this is the additive identity (point at infinity). the point at infinity cannot be normalized.

val x: ModularBigInteger

x coordinate of the point (x,y)

xBytes

val xBytes: ByteArray

val y: ModularBigInteger

y coordinate of the point (x,y)

yBytes

val yBytes: ByteArray

yCompressed

val yCompressed: Sign

Functions

asPublicKey

fun ECPoint.asPublicKey(preferCompressed: Boolean = false): CryptoPublicKey.EC

double

fun ECPoint.double(): ECPoint

adds this to this and returns the result

equals
