monocypher_embedded
Stripped down version of an excellent Monocypher crypto library (https://github.com/LoupVaillant/Monocypher), for embedded usage (tested on STM32F1, STM32F4, ESP8266 and ESP32 chips).
Why?
Needed for transparent LoRa+Mavlink2 symmetric packeted packets encryption and authentication for my airplane and boat drone projects.
