You'll have to be more specific. You do know that 128 bit encryption was introduced in PDF-1.4 and AES encryption in PDF-1.6. Do you have any idea if you are changing the encryption type between what you call your "old PDF" and your "new PDF". Your question is too vague for this list. -- This answer is provided by 1T3XT BVBA http://www.1t3xt.com/ - http://www.1t3xt.info ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php
