Question on decrypting LoRaWAN payload packets under MicroPython

[Duane Kaufman]

Hello,

My name is Duane Kaufman, and I am interested in decrypting LoRaWAN (Low-Power Radio) payloads on a MicroPython-running microcontroller (LoPy  -https://pycom.io/product/lopy/)

I am a newbie to cryptography, but I found a package written in Python that can decrypt LoRaWAN payloads: https://github.com/jieter/python-lora

Unfortunately, python-lora relies on the cryptography package, which has non-python dependencies.

Can pycryptodome be operated in a pure-python code fashion? Can pycryptodome be used in place of the cryptography package in python-lora? 

Sincerely,
Duane

Hi Duane,

In Pycryptodome most crypto is done in C: it is not a pure-Python package.
