encrypt method

@override Encrypted encrypt(Uint8List bytes, { IV? iv, Uint8List? associatedData, })

Encrypt bytes.

Implementation

@override
Encrypted encrypt(Uint8List bytes, {IV? iv, Uint8List? associatedData}) {
  if (mode != AESMode.ecb && iv == null) {
    throw StateError('IV is required.');
  }

  if (_streamCipher != null) {
    _streamCipher!
      ..reset()
      ..init(true, _buildParams(iv, associatedData: associatedData));

    return Encrypted(_streamCipher!.process(bytes));
  }

  _cipher
    ..reset()
    ..init(true, _buildParams(iv, associatedData: associatedData));

  if (padding != null) {
    return Encrypted(_cipher.process(bytes));
  }

  return Encrypted(_processBlocks(bytes));
}
