Limiting UART access

[arkhantum]

hi guys,
i am newbie here
is it possible to do s/w secure lock once we download the bin into esp ?
so inappropriate people could not access the LOG from our UART, except they have the right key.
How can we do that ?
Thank you

You can encrypt data with a KEY before sending to UART , and when you want to see data,you can decrypt it with your own app+KEY.

Hi alex..

Would you mind to share it. I am a noob in this encryption methode field.
Thanks

AES256 base function ( s-box? )

or/and
