Org.BouncyCastle.Math.EC.ECPoint

public abstract class ECPoint
Base class for points on elliptic curves.
protected static readonly ECFieldElement[] EMPTY_ZS

public virtual ECFieldElement AffineXCoord { get; }

Returns the affine x-coordinate after checking that this point is normalized.

public virtual ECFieldElement AffineYCoord { get; }

Returns the affine y-coordinate after checking that this point is normalized.

public virtual ECCurve Curve { get; }

protected virtual int CurveCoordinateSystem { get; }

public bool IsInfinity { get; }

public virtual ECFieldElement XCoord { get; }

Returnss the x-coordinate.

public virtual ECFieldElement YCoord { get; }

Returnss the y-coordinate.

public virtual ECPoint Normalize()

Normalization ensures that any projective coordinate is 1, and therefore that the x, y coordinates reflect those of the equivalent point in an affine coordinate system.
