Docs · SDK

SDK reference.

Reference implementations for the languages enterprise teams actually ship in. Per-language pages land alongside each SDK as it stabilizes.

Docs vs Spec. Docs explain how to use the SDKs to ship Handshake into your stack. The Spec is the protocol itself, the wire format, the algorithms, what every implementer must agree on. You read Docs once. You cite the Spec.
