Are you using loop-AES and ciphers package kernel modules? If you are trying
to do that with cryptoloop, your attempt is guaranteed to fail.

# lsmod | grep loop
loop_twofish            9788   1
loop                   45392   6  (autoclean) [loop_twofish]
# losetup /dev/loop0
/dev/loop0: [0305]:963002 (/dev/hda7) encryption=twofish160 loinit=1

cryptoloop/cryptoapi twofish does not understand twofish with 160 bit keys.
