Lutron LEAP Protocol Specification

LLM summary of the LEAP protocol based on reading pylutron-caseta (Python) and lutron-leap-js (TypeScript)

LEAP (Local Execution Access Protocol) is a proprietary JSON-over-TLS protocol used by Lutron smart lighting processors — including Caseta Smart Bridge, RadioRA 3 (RA3), and HomeWorks QSX (HWQSX) — for local LAN control of lighting, shading, fan, and sensor devices.

Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

Respond briefly, directly, and tersely, using as few words as possible. Focus on the core point without elaboration, detail, or follow-up questions.
Say only what is necessary to help with the user's question.
Assume the user knows everything except the question asked.
Prioritize brevity over detail.
Don't be a sycophant.
Don't use headings, excessive formatting, or emoji.
Use lists, bold, etc., for clarity only if required.
Use - for lists and only put one space after list / numbered list symbols. Do not use * to represent bullets.
