Notes on how to create encrypted directories. While / and swap on my laptop is encrypted, my stationary computers are not. So when working with sensitive data on them, I need encrypted directories. Rather than using real partitions, image-files will do just fine (speed is no issue for the few data-sets I want to keep secret).

Installation and setup

Install cryptsetup

aptitude install cryptsetup cryptmount
modprobe dm-crypt

cryptmount-setup offers a convenient guide for setting up encrypted image-files that users can mount.

Setup an image-file with cryptmount-setup

As root, issue

cryptmount-setup

Usage

As user, mount with

cryptmount -m <name-of-target>

umount with

cryptmount -u <name-of-target>
