Dear Micheal,

Thanks for the response.

The use of loop-aes requires the kernel module loop.o and the aes key to be fed 

using standard input and uuencoded.  The loop-AES.README is at 

http://loop-aes.sourceforge.net/loop-AES.README

An example from that document to fill an encrypted partition with random data is as follows:

    head -c 15 /dev/urandom | uuencode -m - | head -n 2 | tail -n 1 \

        | losetup -p 0 -e AES128 /dev/loop3 /dev/hda666

    dd if=/dev/zero of=/dev/loop3 bs=4k conv=notrunc 2>/dev/null

    losetup -d /dev/loop3

This example uses a random key with loop-aes, then a dd fill of zeros is converted 

to random ciphertext.  Note the uuencoding of /dev/urandom output and it being

piped into losetup.

I have checked the modules and i am able to load them using modprobe.
