How to programatically find the start and end bytes of LUKS header?

QUESTION

How to programatically find the start and end bytes of LUKS header?

Asked 2020-Mar-18 at 06:47

How can I programmatically determine the exact start byte and exact end byte of a LUKS header on a block storage device?

I use Linux Unified Key Setup (LUKS) for Full Disk Encryption (FDE), so all of the data on my drive is encrypted using a strong master key that's not derived from my passpharse, and I'm working on a script that will securely wipe the drive in an panic/emergency shutdown situation (ie: someone is physically stealing your laptop).

Let's say I have a 1000T drive and time is too short (~30 seconds) in my emergency scenario to actually fill the drive with random bytes. Instead, I'd just like to overwrite the header because all of the data on the drive is worthless if the header (containing the keyslots with the master key and salts) is lost--even if the passphrase were recovered via rubber-hose cryptanalysis.

How can I programmatically safely determine the start byte and end byte of the LUKS header so I know what to overwrite?

Note: The solution provided must be valid for both LUKS1 (released in 2014) and LUKS2 (released in 2018).

In LUKS1, I've found that the start is 0 and the end is determined by multiplying the payload-offset field from the container's binary header by 512. For example

Here's a quick python script that will output the start and end bytes for a given LUKS container:

Install cryptanalysis

You can download it from GitHub.
You can use cryptanalysis like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
