And here is a simple bash-script. Change it to feet it in your sys.

#!/bin/bash

case "$1" in
start)
echo "Mounting encrypted file system - [crypto]"
/sbin/losetup -e aes -k 256 /dev/loop0 /dev/hdc1
/bin/mount -t ext2 /dev/loop0 /cfs
/bin/chmod 770 /cfs
echo "OK"
;;
stop)
echo "Unmounting encrypted file system - [crypto]"
/bin/umount /cfs
/sbin/losetup -d /dev/loop0
echo "OK"
;;
*)
echo "Usage: cfs {start|stop}"
exit 1
esac

exit $RETVAL

'modprobe loop' before 'modprobe cryptoloop' if loop-support is NOT compiled in.

at RH9.0 ALL cryptoAPI modules already there.

DES is a weak cipher.So

'modprobe cipher-aes' and
'losetup -e aes -k 256' instead!!
