There is a feature in PDF called "Crypt Filters" that allows one to encrypt 
only certain streams in a PDF, however iText doesn't support this feature.  You 
are, of course, welcome to add it to iText since you have the source!  Or 
perhaps contract with them for doing the work for you.

Subject: [iText-questions] encrypt/decrypt specific parts of pdf?

Hi,

Is it possible to encrypt/decrypt specific parts of a pdf , say from javascript 
without having the user enter a pwd?  not sure if im being very clear... but 
the examples I see only seem to allow for pwd based enccryption

Cheers
