finish method

@override SerializableHash<HashState> finish(List<int> out)

Finalizes the hash computation and stores the hash state in the provided List

This function completes the hash computation, finalizes the state, and stores the resulting hash in the provided out List

Parameters:

• out: The List

Returns the current instance of the hash algorithm.

Implementation

@override
SerializableHash finish(List<int> out) {
  if (!_finished) {
    final bytesHashed = _bytesHashed;
    final left = _bufferLength;
    final bitLenHi = (bytesHashed ~/ 0x20000000) & 0xFFFFFFFF;
    final bitLenLo = bytesHashed << 3;
    final padLength = (bytesHashed % 64 < 56) ? 64 : 128;

    _buffer[left] = 0x80;
    for (var i = left + 1; i < padLength - 8; i++) {
      _buffer[i] = 0;
    }

    writeUint32BE(bitLenHi, _buffer, padLength - 8);
    writeUint32BE(bitLenLo, _buffer, padLength - 4);

    _hashBlocks(_temp, _state, _buffer, 0, padLength);
    _finished = true;
  }
  for (var i = 0; i < getDigestLength ~/ 4; i++) {
    writeUint32BE(_state[i], out, i * 4);
  }

  return this;
