------------------------------------------------------------------
I tried creating an encrypted file with another software and that one opens
with Adobe Reader on my Android phone. By looking at the files, I found a few
differences: ours is version 1.4 (wrong), has a wrong length near "AESV3" (but
that entry is ignored anyway according to the specification), and we have
revision 6 and the other software has revision 5. However revision 5 is
deprecated. Correcting our minor errors didn't help.
