Read Only PDF
Hi users!
Is it possible to generate a "read only" PDF with Cocoon so that it can't be
modified later with any other pdf tool ?
thanks!

Cocoon 2.1 + Encryption
Posted by Martín Mauri <mm...@profesi.com.ar>.
Hi users,
I've installed everything like appars in
http://wiki.cocoondev.org/Wiki.jsp?page=FOPPDFEncryption but I can't get it
working, could it be a problem with the API? Can anybody tell me what jar
should be placed and where?
I've tried putting bcprov-jdk14-123.jar in the jre/lib directory of my JDK
as well as jboss' lib directory (I'm running jboss/tomcat/cocoon), and I've
also configured the serializer thing in the sitemap file. I can get the app
running though, but my PDF still allows printing and saving...any idea?
thanks!

Hi Martin,
I think there is no way to prohibit the user from saving a pdf file. You
can disable only the printing, copy and editing feature.
But with encryption enabled it isn't so easy to modifiy the file after
it has been saved. There are some tools which can actually crack this
encryption within a short time, but for normal use this shouldn't matter.
Did you have a look at the FOP page and did you install a crypto provider?
Cheers
Matthias

Well, I meant "I CAN still save it with the reader"

Thanks very much Matthias!
I?ve tried that, it seems pretty straightforward, unfortunately I couldn't
get it to work, probably because I'm using embedded Tomcat/Cocoon on JBoss.
I've set up everything as the page says, but when I generate de PDF I can't
still save it with the reader, it supposed I can't do that with encription
isn't it?

Now, I remember some related post in some of the Cocoon list. Search also
the archives: users and devel.

I think FOP provides some extensions to encrypt generated PDFs - you
might want to search the FOP mailing list archives or web site. I think
it is possible but don't know the details.
