I should point out that you can't edit the pdf in Writer, only in Draw.
Drop me a note off-list & I'll try to assist.

owner-password is only used to prevent making changes to the pdf,
user-password is for opening. Try opening in OOo Draw and just hit enter
at the password prompt.

Thank you Gary. I have found a workaround to strip the password. Since
the pdf was readable / printable, I opened in evince and printed to
CUPS-PDF. That rendered a PDF with all the attributes but without the
"encrypted metadata". I do have a question about editing with Draw, but
I'll start a separate thread.


If anyone has thoughts about why pdfcrack might find an owner password
(and no user password), but they don't work, here is the entire output
of pdfcrack. (File name and actual pass changed to protect the innocent).

Run it again without the -o option. It defaults to user password. The
-o option sets it to owner.

Thanks for the thought. It looks like the -o option gives both owner
and user passwords. If you look at the actual output the last two lines
are:

found owner-password: 'situp'
found user-password: '

the same "user-password" is found when running without the -o option.
Gary had suggested just clicking enter when trying to open the file (no
password). That did not work.
