Hi... Adding to the last thread, when I saw your reply to the thread "PdfReader not opened with owner password ", I have tried decrypting a pdf file by user password using iTextSharp 4.0.3 and its working fine.
But is it safe to use iTextSharp version 4.0.3 instead of iTextSharp 4.0.4 for decryption of pdf files in our application? Or does it have any limitations on it?
