I am creating PDF files in either Canvas 7 or FreePDF/Ghostscript, and
I want to give them some protection. I at least want to keep them from
being modified, though I would like to allow only printing.

Yes, I know the knowledgeable can defeat these settings, and I can
find programs to do that. But finding a program to do the opposite is
really a challenge. If there is any freeware that can apply security
settings to existing PDF files, I'd really appreciate help finding it.
