Do you know what's about reading a key raw from a USB stick by dd? In the link you posted nothing is mentioned about cryptsetup.
Damn, I pasted the wrong link. Sorry about that. It should have been: <http://0pointer.de/public/systemd-man/crypttab.html>. So, to decrypt /dev/sda1 using a 1024 bits key stored at an offset of 1MB on the key usb drive /dev/sdd, you would do secret /dev/sda1 /dev/sdd size=1024,keyfile-offset=1024 The missing keyfile-offset entry from the link is: "keyfile-offset= Specifies the number of bytes to skip at the start of the keyfile; see cryptsetup(8) for possible values and the default value of this option."
