Digital signature for a PDF/A file

Aspose.PDF Product Family
1

Hi,
I’m interested in using your libraries in order to:

  • Convert a DOCX document to PDF
  • Convert the above PDF document to a PDF/A document
  • Sign digitally the above PDF/A document

I read the documentation and the above operations should be possible to do, but I need a confirmation from you that there are not issues about the topics because we don’t have too much time to spend in investigate the libraries.

Also the correct procedure is to convert before the document from PDF to PDF/A and then sign it, or it’s more correct to sign the PDF and then convert it to PDF/A?

Best regards.
Claudio
