[HowTo] use a password to edit filled PDF

[tuxtux59]

Hi,

I guess I missed something but I can't achieve to lock edition of PDF with a custom password but allow unknown users to read the file BUT forbid them to edit the file without the password.

pdftk.fill_form tempform,
                    tempfile,
                    data.as_json,
                    encrypt: true,
                    encrypt_options: 'user_pw secret allow printing'

Second question is secret the password set in the command above ?

Thanks a lot !
