    pyHanko: sign and stamp PDF files

    • If you aren't afraid of some command-line tooling, you can use pyHanko: https://github.com/MatthiasValvekens/pyHanko/. It's mainly a signing tool, but the library behind it supports literally every encryption scheme in the PDF standard. The CLI is a bit more restricted, but it'll probably still do the job in this particular case.
