Hello

I use itext in servlet with stream like this:

Document document = new Document(PageSize.A4, 50, 50, 70, 70);

ByteArrayOutputStream baos = new ByteArrayOutputStream();

PdfWriter writer = PdfWriter.getInstance(document, baos);

And to disallow modification on this document I only know "PdfEncryptor".

But "PdfEncryptor" work with files.

So can I protect my document against modification without write it
temporally on web-server.

Thanks,

Laurent
