[jira] [Commented] (PDFBOX-4048) isOwnerPermission() true despite having used user password

Tilman Hausherr commented on PDFBOX-4048:
-----------------------------------------

I traced StandardSecurityHandler and it is the owner password. I then made a small change to call {{isUserPassword()}} first and the result is true. So the password is *both* the user and the owner password.

> For the attached file, {{isOwnerPermission()}} is true despite that the password is the user password (according to the user). This was a SO issue ( https://stackoverflow.com/questions/48035060/pdf-in-mac-preview-shows-its-only-readable-but-pdfbox-says-editable ) but it has been removed since then.
> {{getPermissionBytes()}} returns FFFFFFFC but when looking at the file with PDFDebugger bits 4 and 6 are false.
