Implementation of the MLS Combiner (draft-ietf-mls-combiner-02) -- an amortized post-quantum MLS combiner built on top of OpenMLS.
MLS is a secure group messaging protocol. The MLS Combiner runs a classical and a post-quantum MLS group in parallel and combines their key material to provide post-quantum security. The "amortized" aspect batches the post-quantum operations across multiple epochs, reducing per-message overhead.
