Using DTLS, with UDP, and generalized packet objects #188
Description
End Goal
Using DTLS for LoRa data. Why? Because I'm using the RFM95 (sx1276) module that doesn't appear to have encryption, and the RFM69 (sx1231)modules (that do have encryption) are using AES ECB, which is bad for the highly repetitive nature of my packets.
Intermediate Goal
Enable DTLS for ordinary UDP sockets, using mbedtls, which is already used in ussl.
Doing this for UDP sockets seems relatively straight-forward, as all µPy sockets implement an underlying "stream" protocol, thus the ussl module will work, with some modification.
It would be nice if there were a generic µPy "stream" protocol class that could be subclassed (to talk to LoRa, which is very UDP-like), and handed directly to (modified for DTLS) ussl for wrapping -- or is there already?
