OTP Gadget Wiki
Builder-facing docs for the Matrix Mole one-time-pad gadget. Everything you need to understand, build, and use the device.
This wiki is hand-written. Each page that mirrors something in the public matrix-mole/otp-gadget repo declares the source file it's based on, so a drift checker can flag pages that fall behind the upstream docs.
Where to start
- New to the gadget? Start with What is the OTP gadget?.
- Buying a built one? See Building one.
- Building it yourself? Skim Is this for you?, then walk through Bill of Materials → Case → Assembly → Firmware in order.
- Using a finished gadget? Jump to Key exchange.
