Yesterday, I discovered PDF Password Remover v7.3.0 on this forum. I did some research and found that the latest version, v7.5.0 (last updated mid-2019ish, I believe) is available on their website.
It can be registered with the following keys (disconnect from the internet, process a password-protected PDF, and it'll ask for registration code. Enter it then):
I recommend this software; I had been looking for some open-source stuff to remove passwords from some certificates so I could edit them, but all the open source scripts I found supported a max of Security Level 5 or so. PDF Password Remover supports Level 6, which is what the documents had. Note: Someone on another forum said that the Windows Portable version of PDF Password Remover reduced the quality of the output PDF. I didn't notice any quality reduction, but I used the installer version with fully-OCR, text-only PDFs - your mileage may vary with image-based PDFs. You could also try the alternatives.
Alternatives:
You can also just open a password-protected PDF in Chromium (Firefox output created an image PDF from my text-only PDF, which is bad), select "Print to PDF", and you'll get a password-free editable copy. Use Adobe Acrobat Pro XI, DC or ABBYY FineReader to edit your PDFs. You could also try Mgosoft PDF Password Remover.
