No, I do not want to sign the torrent file. I want the ISO image and a gpg
signature for that inside the torrent file. Even if anybody fools you, signs
his own ISO with his own key and puts these into a torrent file you can easily
verify after download:

$ pacman-key -v archlinux-2013.01.04-dual.iso.sig
==> Checking archlinux-2013.01.04-dual.iso.sig ...
gpg: Signature made Thu 31 Jan 2013 01:56:51 PM CET using DSA key ID 2409C107
gpg: Can't check signature: No public key
==> ERROR: The signature identified by archlinux-2013.01.04-dual.iso.sig
could not be verified.

Output should look like this though, note this only happens if the key is in
pacman's keyring and trusted with the required level:

$ pacman-key -v archlinux-2013.01.04-dual.iso.sig
==> Checking archlinux-2013.01.04-dual.iso.sig ...
gpg: Signature made Fri 04 Jan 2013 11:07:27 PM CET using RSA key ID 9741E8AC
gpg: NOTE: trustdb not writable
gpg: Good signature from "Pierre Schmitz <pierre at archlinux.de>"
