We have done a project with Raspberry Pi 3B. I have read something about filesystem encryption of the Raspberry Pi/Raspbian. Also, I read this question which answered years ago (too old!). I didn't understand the ways. My purpose is to prevent spoiling system files of Raspbian.

In this link they suggest a module/board which I do not prefer using that.

Situation details:

  • A camera connected by a USB port with no additional driver.
  • A USB sound card connected with no additional driver.
  • An Arduino connected by USB (RS232).
  • Some relay connected by GPIO pinout.
  • Raspberry Pi 3B.
  • Raspbian Buster.

The thing that I'm looking for is a procedure that helps me to encrypt whole (/boot isn't important) the SD-Card.

Thanks in advance.

    Not tried this but https://www.zymbit.com/zymkey/ I don't know what happens if you need to fix a bug! – CoderMike Jan 21 '20 at 11:50

    You can reverse engineer something without ever having to violate any security; the only way to prevent it is to never allow anyone to use the software. Of course, there are specific reverse engineering techniques that have more specific requirements and are preventable. In any case, that stuff isn't really on topic here. What would be are details concrete to the Pi, eg., how to encrypt a filesystem, etc. – goldilocks Jan 21 '20 at 12:18
  • Is good ole LUKS not an option for the rpi platform? Too processor intensive? – 0xSheepdog Jan 21 '20 at 15:53
  • @CoderMike Bugs isn't important. As I searched, zymbit has a hardware module. Is that right? – M. Rostami Jan 23 '20 at 15:23
  • @goldilocks Thanks, I've edited the question. – M. Rostami Jan 23 '20 at 15:23
  • @0xSheepdog What's ole LUKS? – M. Rostami Jan 23 '20 at 15:24

    @M.Rostami Linux Unified Key Setup disk encryption. I'm pretty good with Linux, fairly new to RPi. No idea if it would work effectively on RPi. – 0xSheepdog Jan 26 '20 at 22:30
