mls-rs   Build Status Latest Version API Documentation codecov

An implementation of the IETF Messaging Layer Security end-to-end encryption (E2EE) protocol.

What is MLS?

MLS is a new IETF end-to-end encryption standard that is designed to provide transport agnostic, asynchronous, and highly performant communication between a group of clients.

MLS Protocol Features

  • Multi-party E2EE group evolution via a propose-then-commit mechanism.
  • Asynchronous by design with pre-computed key packages, allowing members to be added to a group while offline.
  • Customizable credential system with built in support for X.509 certificates.
  • Extension system allowing for application specific data to be negotiated via the protocol.
  • Strong forward secrecy and post compromise security.
  • Crypto agility via support for multiple cipher suites.
  • Pre-shared key support.
  • Subgroup branching.
  • Group reinitialization for breaking changes such as protocol upgrades.

Features

  • Easy to use client interface that can manage multiple MLS identities and groups.
  • 100% RFC 9420 conformance with support for all default credential, proposal, and extension types.
  • Support for WASM builds.
  • Configurable storage for key packages, secrets and group state via traits along with provided “in memory” and SQLite implementations.
  • Support for custom user proposal and extension types.
  • Ability to create user defined credentials with custom validation routines that can bridge to existing credential schemes.
  • OpenSSL and Rust Crypto based cipher suite implementations.
  • Crypto agility with support for user defined cipher suite.
  • Extensive test suite including security and interop focused tests against pre-computed test vectors.
