getEncryptAlgo method

Future<CPDFDocumentEncryptAlgo> getEncryptAlgo()

Get the encryption algorithm of the current document

example:

CPDFDocumentEncryptAlgo encryptAlgo = await controller.document.getEncryptAlgo();

Implementation

Future<CPDFDocumentEncryptAlgo> getEncryptAlgo() async {
  String encryptAlgoStr = await _channel.invokeMethod(
    'get_encrypt_algorithm',
  );
  return CPDFDocumentEncryptAlgo.values
      .where((e) => e.name == encryptAlgoStr)
      .first;
}
