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).
> 6. Would I need to reboot to have full functionality?
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 =3D "echo $body | /usr/bin/gpg --homedir /home/username/.gnupg=
-a -r 'Full Username' -e -";
if ($debug=3D=3D1) {
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!
> Could you be *VERY* specific on how to do this? ;^)
Sure! Just send $29.95 (plus $11.23 s/h) for my three-step program. ;-)

No problem. Good luck!
