If I format partition with dm-crypt does its entry in partition table suggest somehow that this partition is encrypted or for someone from outside it looks like regular partition with random noise stored on it? My goal is to encrypt partition and to make in undistinquishable from regular partition that was just formatted or erased by cat /dev/urandom > /dev/sda1.
Does DM-Crypt partition look like random noise?
