public virtual ECLookupTable CreateCacheSafeLookupTable(ECPoint[] points, int off, int len)

Create a cache-safe lookup table for the specified range of points. All the points MUST belong to this ECCurve instance, and MUST already be normalized.

public abstract bool IsValidFieldElement(BigInteger x)

public virtual void NormalizeAll(ECPoint[] points)

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.

public virtual void NormalizeAll(ECPoint[] points, int off, int len, ECFieldElement iso)

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.

public virtual PreCompInfo Precompute(ECPoint point, string name, IPreCompCallback callback)

Compute a PreCompInfo for a point on this curve, under a given name. Used by ECMultipliers to save the precomputation for this ECPoint for use by subsequent multiplication.
