Encryption - ARK

[patrikpordi]

Solved Problem

Making creating encrypted board files and then log download and decryption easier

Solution

Creating scripts to generate keys, dowload the logs and then decrypt them

Context

Navigate to the Tools folder
python3 key.py

make your ark board and upload it to the flight controller
python3 download_logs.py serial:/dev/ttyACM1:57600 (I have only tested the serial)
python3 decrypt_logs.py
Your logs should be found in
PX4-Autopilot/log/decrypted_logs$

Let's put these new scripts in their own dir, maybe Tools/log_encryption/. Let's also add a README to this new dir that explains how to use

[hamishwillee]

There is nothing about these scripts that says they are not generally useful. So when this merges, can you update https://docs.px4.io/main/en/dev_log/log_encryption.html ?

[dakejahl]

Rather than create a new file with a new name decrypt_logs.py why don't we update the existing decrypt_ulog.py?

Can you add this to the Tools/setup/requirements.txt file?
