I'm currently trying to develop a program that sets Encrypted PDF permissions using the PDFBox Framework(www.pdfbox.org). I've already decrypted the PDF and am capable of setting the the dictionary's permission flag, But I'm at a loss at reencrypting the file. Should I reencrypt and reuse the old trailer with the new permissions + username/password? Should I generate a new trailer? I would be grateful for any advice on the matter.
