I do not know, where the problem is, because I have not
seen the source code. The fact remains, that the code
of \pdfobj, attributes by attr or user and ... have to
be checked, whether there are strings or streams, because
they have to be encrypted, too.

I have send you two files in the list and two other files
per mail. I think short plain-TeX files will help you more,
than complicate LaTeX files with hyperref, thumbpdf ...
But if the known problems are solved, you can try the
test files of hyperref (especially for links, bookmarks,
forms, ...).
