gbp-mls

MLS (RFC 9420) integration for the Group Protocol Stack.

This crate wraps openmls 0.8 and adds a ChaCha20-Poly1305 AEAD layer driven by MLS labelled exporters (gbp/control, gbp/audio, gbp/text, gbp/signal).

The MlsContext::export_raw(label, context, len) method exposes the raw MLS exporter for custom labels — used by gbp-sframe to derive sframe_base_key = MLS.ExportSecret("gbp/sframe v1", epoch_be8, 32).
