Can Bypass PDF Security Features
Currently I'm using preinstalled Evince from my Pop OS and I've found that Evince can bypass Encrypted PDF Permissions. I encrypted my PDF with PDFtk cli. When I open my PDF, Evince normally asks password to open my PDF. Then, I typed my user password to check whether the Encryption works or not. So, I tried to print my PDF to test and it is printed. I didn't give any permissions to my user password. Images containing in my PDF can also be saved without asking permission password. I encrypted my PDF with PDFtk cli with 128bit encryption. Any PDF viewer asks permission password to do print or something like this but except Evince. I also tested with other encryption tools and the result is the same and printing and others can be done without asking permission password!
