Re: [iText-questions] How to sign the PDF file that has the signing permission without setting owner password
I have a similar problem, I need to set the permissions for a itext generated report for compliance rules that have to do with the Financial Planning industry. I need the client to be able to read files I generate with out a password but I also need limit their permissions with the file. Is there a fast track for itext requests?

Re: [iText-questions] How to sign the PDF file that has the signing permission without setting owner password
No. What use would a set of permissions be that enabled anyone to get access!??! However, you can apply digital rights to a file via encryption WITHOUT requiring a password to open the file...

indeed but when I try to reopen that file with a PDFReader, to concat it, it complains that I am not using the correct owner password.

[iText-questions] How to sign the PDF file that has the signing permission without setting owner password
Hello. I have a question about the signing of PDF with iText. I know that PDF encryption spec. provides the permission to allow signing and adding annotations. I can sign a PDF file using Acrobat without typing owner password if it has the permission to allow signing. But, iText always needed owner password to sign on the PDF files, although they already had the signing permission, when I made some test codes and tried them. To be specific, PDFReader can read the PDF files encrypted without setting owner password but error occurs at PdfStamper.CreateSignature method. If I set owner password at the constructor of PDF reader, the error disappears. But, I have to insert signature without owner password at my scenario. My test codes are based on the article – How to sign a PDF using iText and iTextSharp and work well with unencrypted PDF files. How do I sign on the PDF files that they are encrypted but have signing permission? Strictly speaking, I want to know that it is possible to sign them with iText.
