Master's project at USF. Added public key encryption and digital signatures to Meshtastic, the open-source LoRa mesh networking platform. Won Best Master's Project.
Submitted PR #251 to meshtastic/protobufs proposing the protocol buffer changes needed for PKC. Meshtastic later shipped native public key cryptography in v2.5 — the maintainers called it "a grandchild of this effort."
This project led directly to Vibetastic, my ongoing mesh networking work.
