@rampujar,

Thanks for contacting support.

You may check Count Property of Form Class of a Document type, in order to determine whether a PDF contains forms or not. Please check following code snippet:

Document doc = new Document(dataDir + "input.pdf");
var count = doc.Form.Count;

In case you are unable to achieve what you require, please share your sample PDF document with us. We will test the scenario in our environment and address it accordingly.

@rampujar,

I have observed the requirements shared by you and have created an investigation ticket with ID PDFNET-48019 in our issue tracking system to investigate whether it is possible to meet the illustrated requirements using Aspose.Slides or not. I will share the feedback with you in this regard as soon as possible.

Yes, you can achieve your requirements by using Aspose.PDF for .NET. You can use encrypt with empty user-password and set DocumentPrivilege.

var document = new Aspose.Pdf.Document(dataDir + "short.pdf");
using (var sec = new PdfFileSecurity(document))
{
    var per = DocumentPrivilege.AllowAll;
    per.AllowAssembly = false;
    sec.EncryptFile("", "owner password", per, KeySize.x256);
    sec.Save(dataDir + "result.pdf");
}

You can change DocumentPrivilege as you wish.
