saveState method

List<int> saveState()

Saves the current hash computation state into a serializable state object.

This method saves the current state of the hash computation, including the data buffer, hash state, and etc, into a serializable state object. The saved state can be later restored using the restoreState method.

Returns a HashState object containing the saved state information.

Implementation

List<int> saveState() {
  if (_finished) {
    throw MessageException("SHA3: cannot save finished state");
  }
  return List<int>.from(_state.sublist(0, _pos));
}
