Password protect
Encrypt a PDF with a password. Unlike the rest of hamarapdf, password protect is handled on your own ModelCam server, because real PDF encryption cannot be done safely inside a browser. The tool says so before you choose a file. Runs on your ModelCam server (qpdf) — the only tool that leaves your device, because real encryption must.
