Hello, I am trying to play around loopback device and want to set up an encrypted loopback filesystem. I did the following things: 1. losetup -e serpent /dev/loop0 /etc/crypt /ect/crypt: Is a directory So I tried: losetup -e serpent /dev/loop0 /etc/cryptfile and this time cryptfile is a plain txt file. Enter passwd... 2. mkfs -t ext2 /dev/loop0 3. mount -t ext2 /dev/loop0 /mnt/crypt After this, how do I verify that anything happened that has enabled encryption? I can't understand where the encrypted filesystem lies in here:( Plus, when we say 'encrypted', which file is on earth encrypted? Is that files and data in /mnt/crypt are encrypted form of /etc/cryptfile? Really confused. TIA!
