Dm-crypt

This tutorial is about how to set up a crypted partition on linux using dmcrypt.
Of course, you can use either fisical partitions or files using a loopback device.

Loopback or partition?

A loopback means that you have a file that is on a partition that you then mount using a special device called a loopback. The loop device then acts as a normal block device transforming your file into just another hard disk :)
