If qpdf exists it is probably not a legal issue to do password protection then.
Of course.
But from the same perspective ... one first needs PDF to be (almost) finished before being able to sign it. One needs to read as-good-as the whole PDF, read the certificate from somewhere on the disk and then sign with that certificate. If certificate is password-protected, one also needs to provide the password somehow.
You can technically sign only parts (IIRC streams) of a PDF.
government. On the other hand they could just as well have used some standard tool and it would work out of the box. So much about signing ...
