encrypted image as safe

Have aes and cryptoloop loaded

dd if=/dev/zero of=/save.img bs=1024k count=100

--> creates an image of 100 MB

losetup -e aes /dev/loop0 /save.img

you can delete this again with -d, but for a new access to loop0 you will need a reboot --> assigns loop device and password to device

mkfs.ext3 /dev/loop0

--> formats the device with ext3

mount -o encryption=aes /safe.img /secret

--> mounts the image with password prompt Or enter into /etc/fstab:

/safe.img /secret ext3 rw,user,loop=/dev/loop1,encryption=aes 0 0
