When I create a document in LO Writer and want to protect the editing of the text in a PDF, I select ‘Export as PDF’, click on the ‘Security’ tab and set the password up, but in permissions only. Selecting the ‘Not permitted’ radio buttons, I click on Export and save the file. However, when I open up the file in Draw and click ‘Cancel’ when prompted for a password, I am able to easily change the text. I though that for some reason it was somehow still holding my password as it was on the same system, but when trying to open the file in another system, it still works. This does not seem very secure, as anyone with LO Draw can edit my text.
Following is a simple file protected as above. When prompted for the password, click ‘Cancel’. Then try editing.
