Element Call uses HKDF-SHA256 + AES-128-GCM for frame encryption, while the LiveKit Rust SDK defaults to PBKDF2 + AES-256-GCM. - Multi-stage Dockerfile builds patched Rust FFI from EC-compat fork - Generates Python protobuf bindings with new fields - patch_sdk.py modifies installed livekit-rtc for new proto fields - agent.py passes E2EE options with HKDF to ctx.connect() - bot.py exchanges encryption keys via Matrix state events - Separate Dockerfile.bot for bot service (no Rust build needed) Ref: livekit/rust-sdks#904, livekit/python-sdks#570 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

E2EE HKDF constants and helpers for Element Call compatibility.

The patched SDK (via patch_sdk.py + patched FFI binary) adds:
|
|
- key_ring_size (int, field 5 in proto)
|
|
- key_derivation_function (int, field 6: 0=PBKDF2, 1=HKDF)
|

This module provides constants and a convenience function for building
|

HKDF-compatible E2EE options.
