Add a Password to a PDF

Silly reminder for self. To add a password to a PDF:
pdftk infile.pdf output outfile.pdf userpw password
Obviously, you need to install pdftk to do this.


Many places you see online say it has to be "user_pw", which is also what the pdftk manpage says, but the underscore appears to be optional.
