            Description

            Crypt filters are a relatively new addition to PDF encryption. We are starting to see more and more documents using crypt filters as Adobe users upgrade to version 8 or 9 of Acrobat. The bug is a place holder for implementing a crypt filter manager and hooking it up to our stream chaining read and write capabilities.
