How to digitally sign and password protect a pdf

   Hi all,
I've already posted a similar question in the forum.
http://www.quickpdf.org/forum/signing-a-password-protected-document_topic3728.html 

I'd like to know if, with QuickPdf v11.13 or newer, is it possible to:
- Load a PDF
- Password protect it (permissions password)
- Digitally sign it and save in a new document.

So, the output PDF should be digitally signed and password protected to avoid modifications.

If it is possible, any guide or hint would be much welcome.

Thank you very much.

	not in one process! You can set a password in the first process and reload the file in a further process to sign it. Passwords can be set directly into a pdf and within the sign process. This will give you an idea: https://www.debenu.com/docs/pdf_library_reference/SignFile.php This will give you a sample: https://www.debenu.com/kb/add-visual-digital-signature-to-a-pdf-programmatically/

	Presently it can be done with QuickPdf's latest release, version 16.13. Thank you for your help.
