The PDF document is signable or not in the document properties

Aspose.PDF Product Family
1

I find if there is a property to know if the PDF document is signable or not in the document properties with Aspose.Pdf.

I looked for information on your documentation as well as on many forums but could not find what I am looking for.

Does the property exist or is impossible to be able to use this data?

Thank you in advance for your reply,

Best regards

You can find out if a PDF is signed or not by using the following code snippet. However, the property to determine the capability of signing a PDF does not exist in the API. Can you please share a PDF which cannot be signed so that we can further investigate the feasibility of this feature and share our feedback with you. Usually, you can sign a PDF document whether it contains a Signature Field or not.

Facades.PdfFileSignature pdfSign = new Facades.PdfFileSignature();
pdfSign.BindPdf(dataDir + "prueba.pdf");
if (pdfSign.ContainsSignature())
{
 // do stuff
}

Thank you for your reply.

I cannot give you the PDF document due to sensitive data. The property is visible on Adobe in the signature tab.

Below is an example of the property I will want to get in C # code to exploit it :
