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

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?

@jlaitine I heard that you originally implemented encryption for logs. Could you take a look at this PR to ensure it doesn’t interfere with your work? I’ve just made it more user-friendly by adding some scripts that make it accessible to non-developers.

@jnomikos might also be a good person to ask. He just updated the docs on log encryption.

Note, @patrikpordi also please check and update the docs if needed to match this. Docs are now maintained in the /docs tree in this repo.

Looks good to me :)
