neg static method

List<int> neg(
  1. List<int> scalar
)

Negates a scalar value and returns the result as a List<int>.

This method negates the given scalar and stores the result in the out List<int>. The negation is performed according to Ristretto255 scalar operations.

Parameters:

  • scalar: The scalar value to negate.

Returns: A List<int> representing the negated scalar.

Implementation

static List<int> neg(List<int> scalar) {
  final out = List<int>.filled(32, 0);
  CryptoOps.scMulAdd(
      out, CryptoOpsConst.scMinusOne, scalar, CryptoOpsConst.zero);
  return BytesUtils.toBytes(out);
}
