Cryptsetup utility provides a simple way to encrypt our external storage units , which normally connect through USB port, protecting the units so that even if we lose the data that we stored can not be decrypted by any onlookers.
to use it, as shown in HowToGeek, simply install the tool, which in Ubuntu is done with the simple command :
sudo apt-get install cryptsetup
after which we can verify the operation of the utility, which works closely with the Ubuntu disk utility , we can launch from the Dash to Ubuntu. If we did not have enough installed to install the package gnome -disk-utility .
the original article shows the different steps, which basically explains that have to format the drive again , so it should pass the data we had on the drive or partition to another device hard disk, with a special format that will encrypt the partition that you indicate and will allow you to access it only through a password we set during the process.
unit may not be used on other computers that do not have the GNOME desktop available because the technology uses LUKS (Linux Unified Key Setup), but if that does not concern you, Cryptsetup can be a valuable guarantee to protect our external storage drives.
