A WIP Rust implementation of Messaging Layer Security based on draft 9+.
- MLS10_128_HPKEX25519_AES128GCM_SHA256_Ed25519 (MTI)
- MLS10_128_DHKEMP256_AES128GCM_SHA256_P256
- MLS10_128_HPKEX25519_CHACHA20POLY1305_SHA256_Ed25519
OpenMLS is built and tested on the Github CI for the following rust targets.
- x86_64-unknown-linux-gnu
- i686-unknown-linux-gnu
- x86_64-pc-windows-msvc
- i686-pc-windows-msvc
- x86_64-apple-darwin
Additionally, we're building and testing aarch64-unknown-linux-gnu on drone.io.
The Github CI also builds (but doesn't test) the following rust targets.
- aarch64-apple-darwin
- aarch64-unknown-linux-gnu
- aarch64-linux-android
- aarch64-apple-ios
- aarch64-apple-ios-sim
- wasm32-unknown-unknown
OpenMLS does not implement its own cryptographic primitives. Instead, it relies on existing implementations of the cryptographic primitives used. There are two different cryptography backends implemented right now. But consumers can bring their own implementation. See traits for more details.
OpenMLS requires at least Rust 1.56.0.

This repository is a cargo workspace with the OpenMLS library as the main component.
In order to use OpenMLS an implementation of the traits is required. This repository provides two default implementations
It further holds the following crates that are used for testing.
A basic delivery service can be found in delivery-service/ds. To interact with the delivery service the ds-lib provides the necessary types.
A basic command line client can be found in cli. Note that this is a PoC for testing and must not be used for anything else.
