update method

@override SerializableHash<HashState> update(List<int> data, { int? length, })

Updates the hash computation with the given data.

Parameters:

• data: The Containing the data to be hashed.

Implementation

@override
SerializableHash update(List<int> data, {int? length}) {
  if (_finished) {
    throw CryptoException.failed("SHA.update", reason: "State was finished.");
  }
  int dataLength = length ?? data.length;
  int dataPos = 0;
  _bytesHashed += dataLength;

  if (_bufferLength > 0) {
    while (_bufferLength < getBlockSize && dataLength > 0) {
      _buffer[_bufferLength++] = data[dataPos++] & BinaryOps.mask8;
      dataLength--;
    }

    if (_bufferLength == getBlockSize) {
      _hashBlocks(_temp, _state, _buffer, 0, getBlockSize);

      _bufferLength = 0;
    }
  }

  if (dataLength >= getBlockSize) {
    dataPos = _hashBlocks(_temp, _state, data, dataPos, dataLength);

    dataLength %= getBlockSize;
  }

  while (dataLength > 0) {
    _buffer[_bufferLength++] = data[dataPos++] & BinaryOps.mask8;
    dataLength--;
  }
  return this;
