You bet.

I'd recommend it, if only to get the most recent security patches for your
system.

The '-a' will upgrade everything on your system.  Is that what you want?
Another option may be:

    # portupgrade -N security/gnupg

which will upgrade all dependencies, then install gnupg.

I'm pretty sure you'll need to be root (or using sudo to execute the
commands as root).

Not likely at all.  I'd be very surprised if any of this required a reboot.

Yep.

Sure.  The second one has this block:

$commandline = "echo $body | /usr/bin/gpg --homedir /home/username/.gnupg -a -r 'Full Username' -e -";
    if ($debug==1) {
      system($commandline);
    } else {
      exec($commandline,$encrypted);
    }

If you've already written the mailer, you could probably stick the above
(modified to suit) somewhere before the mail() function and leave the rest
of your script intact.

>>5) Profit!

Sure!  Just send $29.95 (plus $11.23 s/h) for my three-step program.  ;-)

No problem.  Good luck!
