<pre>The problem is that the file is encrypted using empty password.
- Try to open the file with Draw and enter any string. You will get: "The
password is incorrect. The file cannot be opened."
- Delete the string making the password field empty and press OK. The file is
opened. The password is null.
I have many financial statements that are encrypted using empty password. There
are reasons, mostly relevant for Adobe products, for using empty passwords. I
I also attached a demo PDF encrypted with empty password via qpdf. Programs
such as Adobe Reader, Chrome / Chromium, Firefox, Evince, Okular, GIMP, and
ImageMagic, and others don't prompt for password when the password is null.
Even programs which has problems with PDF decryption such as Imagemagic and
Inkscape silently open such files.</pre>
