No, that was added to the FAQ a while ago, although in a slightly different form: http://support.itextpdf.com/node/22 That FAQ is about Reader enabled PDFs, but the principle is the same. A Reader enabled PDF is a special kind of signed document. Signed documents must remain intact. However, in your case you could create an encrypted ZIP file that contains the PDF. Or you could create a portable collection and encrypt the portable collection that contains the PDF instead of the PDF itself. ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
