## SignOptions class


Allows to specify options for document signing. To learn more, visit the [Work with Digital Signatures](https://docs.aspose.com/words/cpp/working-with-digital-signatures/) documentation article.

```cpp
class SignOptions : public System::Object
```

## Examples



Shows how to digitally sign documents. 
```cpp
// Create an X.509 certificate from a PKCS#12 store, which should contain a private key.
System::SharedPtr<Aspose::Words::DigitalSignatures::CertificateHolder> certificateHolder = CertificateHolder::Create(get_MyDir() + u"morzal.pfx", u"aw");

// Create a comment and date which will be applied with our new digital signature.
auto signOptions = System::MakeObject<Aspose::Words::DigitalSignatures::SignOptions>();
signOptions->set_Comments(u"My comment");
signOptions->set_SignTime(System::DateTime::get_Now());

// Take an unsigned document from the local file system via a file stream,
// then create a signed copy of it determined by the filename of the output file stream.
{
    System::SharedPtr<System::IO::Stream> streamIn = System::MakeObject<System::IO::FileStream>(get_MyDir() + u"Document.docx", System::IO::FileMode::Open);
    {
        System::SharedPtr<System::IO::Stream> streamOut = System::MakeObject<System::IO::FileStream>(get_ArtifactsDir() + u"DigitalSignatureUtil.SignDocument.docx", System::IO::FileMode::OpenOrCreate);
        DigitalSignatureUtil::Sign(streamIn, streamOut, certificateHolder, signOptions);
    }
}
```
