"root=/dev/mapper/root cryptdevice=/dev/sda5:root
In this case, /dev/sda5 is the encrypted device, and we give it an
arbitrary name of root, which means our root device, once unlocked, is
mounted as /dev/mapper/root. On bootup, you will be prompted for the
passphrase to unlock it." [1]

I'm playing with a plain version of dm-crypt. It doesn't store any
metadata on a disk.
And I don't want to expose that there is an encrypted data.
That's why I'd like to mount and decrypt it by hand.

What are my options?
