How to use a keyfile in conjuntion with a passphrade dm-crypt/LUKS

How would I go about using a keyfile with a passphrase? Example: PC won't let me into Arch unless I have the keyfile (USB flash drive) in, and unless I type the correct passhprase. I know this is possible with TrueCrypt. Is this possible with dm-crypt/LUKS?

Any help would be very appreciated!

You can encrypt the keyfile with a passphrase. Thus you need both keyfile and passphrase to get the actual key that opens your LUKS device.

I described my setup here https://bbs.archlinux.org/viewtopic.php … 1#p1502651
