I've setup a crypted file with the loop device:

nslu2:~# dd if=/dev/urandom of=fwcrypt.loop bs=5000000 count=1
1+0 records in
1+0 records out
5000000 bytes (5.0 MB) copied, 13.0638 seconds, 383 kB/s

nslu2:~# losetup /dev/loop0 fwcrypt.loop
nslu2:~# cryptsetup -v -y -c aes-cbc-essiv:sha256 -s 256 luksFormat
/dev/loop0

WARNING!
========
This will overwrite data on /dev/loop0 irrevocably.

Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase:
Verify passphrase:
Command successful.

After this i've tried to open and got "Command failed":

nslu2:~# cryptsetup luksOpen /dev/loop0 fwcrypt
Enter LUKS passphrase:
Command failed.

nslu2:~# cryptsetup luksDump /dev/loop0
