ok, i understand.

but i tried:

reader = new PdfReader("/home/di/workspace/pdf/teste_de_assinatura.pdf");

PdfEncryptor.encrypt(reader, new
FileOutputStream("/home/di/semdireitos.pdf"),
                    null, null, PdfWriter.ALLOW_ASSEMBLY |
PdfWriter.ALLOW_COPY |
                    PdfWriter.ALLOW_DEGRADED_PRINTING |
PdfWriter.ALLOW_FILL_IN
                    | PdfWriter.ALLOW_MODIFY_ANNOTATIONS |
PdfWriter.ALLOW_MODIFY_CONTENTS
                    | PdfWriter.ALLOW_PRINTING |
PdfWriter.ALLOW_SCREENREADERS , false);

this are all the permissions i could find. but still i have the same
problem (adobe reader says that i can't extract pages, comments,
signature and others)

What am i doing wrong?
Sorry
