------- Comment #4 from bradh at frogmouth.net  2007-10-27 04:08 PST -------
I'm still trying to understand what PDF spec section 3.5.4 is trying to
explain, but this seems relevant:
323 0 obj
<</Length 128/
    CF<</StdCF
        <<
           /Length 16/
           AuthEvent/DocOpen/
           CFM/AESV2
        >>
      >>
    /Filter/Standard
    /...
    /V 4
    /EncryptMetadata false
    /StrF/StdCF
    /StmF/StdCF
>>

Note: I've reformatted it.

The EncryptMetadata false part basically means that all the encryption stuff is
basically pointless. Only the metadata stream has the Crypt filter, and the
crypt filter doesn't apply to the metadata...
