Update - 433Mhz You can't hack this !!

Thanks for the follow up. I think program memory is not the main issue with encryption, especially if you - in my opinion - wast memory for the pre-shared generated key tables. You have to spend CPU-cycles and energy for encryption/decryption. I used in an experimental AVR based 433MHz transmitter/receiver ChaCha20-Poly1305 for encryption and integrity. This worked pretty good for these bit-rates.

Thanks for watching and taking the time to comment. Energy is a key factor for me but honestly I don’t have any base to justify that on, maybe one for another video encryption and hash vs recall from memory. I’ve added ESP32 support and will be looking at deep sleep and overall energy usage. I’m still thinking though, better to be 100% not reversible than reversible but encrypted and hashed. Time will tell. Thanks again.
