We have joined forces with our friends from Phoenix R&D to improve OpenMLS.

The MLS protocol draft is in the IETF working group’s last call and is thus on track to become an RFC soon. We want to make sure that OpenMLS is ready for wider adoption by the time the RFC is ready. To achieve this we start by catching up with all the changes to the protocol (up to the current draft-16), improving test coverage of the code, and working towards a more comprehensive test framework for interoperability.

This is part of Cryspen’s larger effort to make end-to-end encryption ubiquitous in any application. Cryspen is also working on formalising and extending MLS to be usable in many more scenarios as well as a formally verified implementation all variants. The results will make it easy for any application to use end-to-end encryption.

We want to thank the Sovereign Tech Fund for funding OpenMLS as the first project in its pilot round.

Please get in touch if you have any questions about key management, encryption, or MLS and OpenMLS.
