Description
File open passwords obviously work fine. For PDFs with permission passwords, John will recognize the PDF as encrypted, and declare it has found a password, but the password field is blank. I don't see any information about permission passwords for PDF's on the forum. I may have missed it. But I was curious, if this was worthy of a feature request if it's not already present.

Research direction
Start by reproducing the behavior with a PDF that has a permissions password, then inspect the existing PDF encryption handling and how the password field is reported. Done means John can process permission-password PDFs without reporting a blank found password, with behavior confirmed by a focused test or reproducible sample.
