Stamp already encrypted PDF documents

Sometimes it is neccesary to encrypt PDF documents to prevent changes or extracting content of them. As encryption is a high performance task the SetaPDF-Stamper API Pro version offers the facility to stamp already encrypted documents without the re-encrypting the whole document but just the new content. Which leads into a performance boost when delivering stamped and encrypted documents.

This solution is perfect if you offer PDF documents that were not encrypted with a user password (the password that is needed to open the document) but the encryption "just" restricts features like copy&paste.
