...it will end up like this:

pdftk input.pdf input_pw SOMETHING output output.pdf allow FillIn

I've had pdfcrack running (in the default mode) on another machine for

I tried it with the -w /etc/dictionaries-common/words option: it
finished very quickly with failure.  Does that just try each word in
