Open the encrypted volume so we can place a filesystem on it.
This will overwrite data on /dev/sdb1 irrevocably. Generate a random key for use with the encrypted volumeīhoward10:/mnt # cryptsetup -v -s 256 luksFormat /dev/sdb1 key.The end result is that some-one looking at the system will be unable how much of the drive has data, as it will all look random. Time can be a couple of hours for larger drives or slow machines. For each partition, or logical volume that you are going to use, simply type “dd if=/dev/urandom of=DEVICE”. You understand that there will be a minimal performance hit (more noticeable if on a laptop)ĭepending on whether or not you belong to the Tinfoil hat conspiracy theorist camp, you might want to put all sorts of random data.

You are familiar with the devices on your system and how to find USB storage devices. You are familiar with the basics of encryption. Using this guide you can setup a LUKS encrypted volume with USB key authentication that will mount the volume using USB key authentication or ask for a password when the system is booted up. SuSE Linux supports LUKS or Linux Unified Key Setup, which supports multiple keys. With modern computers, using software based encryption will not have a noticeable performance hit unless you have a slow hard disk or an older CPU. The risk of having that data leaked, is greater than the minimal performance hit than doing disk based encryption. Data like financial, business secrets, and medical records, among a few, are extremely sensitive. For most system administrators, desktop users, auditors and managers, data is extremely import.
