Description:
secs 0.2.0
Simple Encrypted Container Setup (SECS) is based on Linux Unified Key Setup
(LUKS). Because good Linux Unified Key Setups mean great Simple Encrypted
Container Setups.
Purpose
If you are unfamiliar with LUKS encryption, it is most commonly used to encrypt
entire disk partitions on Linux. However, it is also capable of encrypting files
which can be mounted as a loop device, allowing you to create portable encrypted
containers to keep different types of sensitive data isolated.
This script is a wrapper to simplify the steps required to create and use these
containers.
Installation
SECS can be installed using pip.
$ sudo pip install secs
# or
$ pip install --user secs
Either command will install a script called secs which provides all the
functionality.
SECS requires root access to run. Note that if you use the second install
option, you will likely have to use sudo -E so that Python can find the
package.
You may find it convenient to use a simple script like the bash script
included in the repo to call sudo for you.
Examples
Root access (e.g. via sudo) is required for all commands.
Create a container. The number is the size in megabytes.
$ sudo secs create work_stuff 100
...
$ ls -Ap
work_stuff
Open a container. The default moves the container to .<container> and mounts
to the container path. Use -m to set an explicit mount path.
$ sudo secs open work_stuff
...
$ ls -Ap
work_stuff/ .work_stuff
Close a container. The default unmounts from the container path and moves the
container back to it’s original path. -m to set the mount path is required
if it was used when the container was opened.
$ sudo secs close work_stuff
...
$ ls -Ap
work_stuff
Expand a container. The number is the amount in megabytes to increase the size
of the container by.
$ sudo secs expand work_stuff 10
Implementation
secs is written in Python and is based on the LUKS specification. It requires
that cryptsetup be available. It is currently written to use ext4 as the
container filesystem. As such, this script will likely only work on Linux
systems.
There are no external Python dependencies. The script may be freely copied
anywhere, as long as Python 2 or 3 is available.
