Returns the affine x-coordinate after checking that this point is normalized.
Returns the affine x-coordinate after checking that this point is normalized.
The affine x-coordinate of this point
IllegalStateException if the point is not normalized
Returns the affine y-coordinate after checking that this point is normalized
Returns the affine y-coordinate after checking that this point is normalized

IllegalStateException if the point is not normalized
Description of elliptic curve of point p which belongs to the curve.
Description of elliptic curve of point p which belongs to the curve.
the elliptic curve point
Returns the x-coordinate.
Returns the x-coordinate.
Caution: depending on the curve's coordinate system, this may not be the same value as in an affine coordinate system; use normalize() to get a point where the coordinates have their affine values, or use getAffineXCoord() if you expect the point to already have been normalized.

Returns the y-coordinate.

Computes HMAC-SHA512 hash of the given data using the specified key.
Computes HMAC-SHA512 hash of the given data using the specified key.
the secret key used for hashing
the input data to be hashed

Checks that the type of the value corresponds to the descriptor tpe.
Checks that the type of the value corresponds to the descriptor tpe.
If the value has complex structure only root type constructor is checked.
NOTE, this is surface check with possible false positives, but it is ok
when used in assertions, like assert(isCorrestType(...)), see ConstantNode.
Check if a point is infinity.
Multiply two points.

Negates the given point by negating its y coordinate.
Normalize a sequence of char values.
Normalize a sequence of char values. The sequence will be normalized according to the NFKD normalization form. Implementation that uses java.text.Normalizer. See https://www.unicode.org/reports/tr15/
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.
