OpenMLS

OpenMLS is a Rust implementation of the Messaging Layer Security (MLS) protocol, as specified in RFC 9420.

It is a software library that can serve as a building block in applications that require end-to-end encryption of messages. It has a safe and easy-to-use interface that hides the complexity of the underlying cryptographic operations.

Supported ciphersuites

MLS_128_DHKEMX25519_AES128GCM_SHA256_Ed25519 (MTI)
MLS_128_DHKEMP256_AES128GCM_SHA256_P256
MLS_128_DHKEMX25519_CHACHA20POLY1305_SHA256_Ed25519

Supported platforms

OpenMLS is built and tested on the Github CI for the following rust targets.

x86_64-unknown-linux-gnu
x86_64-pc-windows-msvc
aarch64-apple-darwin
aarch64-unknown-linux-gnu

Unsupported, but built on CI

The Github CI also builds (but doesn't test) the following rust targets.

i686-unknown-linux-gnu
i686-pc-windows-msvc
x86_64-apple-darwin
aarch64-linux-android
aarch64-apple-ios
wasm32-unknown-unknown
armv7-linux-androideabi
x86_64-linux-android
i686-linux-android

OpenMLS supports 32 bit platforms and above.

Cryptography Dependencies

OpenMLS does not implement its own cryptographic primitives. Instead, it relies on existing implementations of the cryptographic primitives used by MLS. There are two different cryptography providers implemented right now. But consumers can bring their own implementation. See traits for more details.

Features

OpenMLS provides the following features

extensions-draft: enable features defined in MLS extensions draft
fork-resolution: helper functionality for resolving forks.
js: enable compilation to wasm

Developer features

libcrux-provider: enable the libcrux crypto provider dependency
openmls_rust_crypto: enable the rust crypto provider
sqlite-provider: enable the sqlite provider
backtrace: enable backtraces
content-debug: allow printing sensitive content of messages for debugging
crypto-debug: allow printing cryptographic key material for debugging
test-utils: test utilities
