module Pdfcrypt:sig
..end
Decrypting PDF files
Note that encryption depends on fixed object and generation numbers: don't
change these (for example by calling Pdf.remove_unreferenced
on the PDF)
before writing.
Encryption support is part of the Pdfwrite
module, since files are encrypted when they're written.
