I have played with this yesterday evening, but without success. I tried

technically it's possible to have no password (at least the specs say so) but i can't get it working;
do you have a file without password that is editable made by another app?
Unfortunately not. Using pdfcrypt I created encrypted but not editable PDF, see http://typokvitek.com/tmp/pdfpermit3.pdf open password 'A', user password 'B'.
it looks like something needs to be done with the stream as well; simply setting a password fails (even the empty one, the funny hex stream); btw, your 252 should be a negative number)
I see. I have to read the specification notes... But in this case the flag number for allowing everything is -4. (see http://typokvitek.com/tmp/pdfpermit4.pdf) In this case all Document Security are allowed, but not Document Restrictions Summary!? Bu still no success with commenting... Vit Zyka
