process method

@override Uint8List process(Uint8List data)

Process a whole block of blockSize bytes stored in data at once, returning the result in a byte array.

This call is equivalent to processBlock but it allocates the array under the hood.

Implementation

@override
Uint8List process(Uint8List data) {
  if (isEncrypting!) {
    var ciphertext = processBlocks(data);
    var tag = finalizeTag();
    var out = Uint8List(ciphertext.length + tag.length);
    out.setAll(0, ciphertext);
    out.setAll(ciphertext.length, tag);
    return out;
  } else {
    var ciphertext = Uint8List.view(
        data.buffer, data.offsetInBytes, data.length - tagLength);
    var inTag =
        Uint8List.view(data.buffer, data.offsetInBytes + ciphertext.length);
    var plaintext = processBlocks(ciphertext);

    var tag = finalizeTag();

    if (!_compareList(inTag, tag)) {
      throw 'Auth error';
    }
    return plaintext;
  }
}
