Show HN: I built an encrypted BLE dongle for pasting stuff to air-gapped devices

Definitely one of those "20 minute adventure gone wrong" projects where all I wanted initially was a quick wireless rubber ducky for bitlocker keys and the like and then I kept adding stuff like AES-256.....

Currently working on adding WebAuthn/FIDO support because the hardware is already there and scope creep is a lifestyle at this point.

Would love feedback, especially on the security side. Repo and PCB files are fully open source.
