I just finished Dart<->Rust bindings for basic methods used by OpenMLS (https://openmls.tech). I like the MLS design so far, just needing to take care of the ratchet_tree state when inviting users is a bit unintuitive. Now it's time to see if everything works and I can get a E2EE group chat going!

I'm using the OpenMLS Rust crate/library, and they still need to make some minor adjustments before it can run on WASM (due to things like time not being available): https://github.com/openmls/openmls/pull/1316

MLS Group State Forks: What, Why, How
Group state forks are faulty states that MLS groups can end up in. We have a new blog post that looks at what they are exactly, how that happens and how to resolve them, and how a a new OpenMLS feature makes fork resolutions a little easier.

MLS Group State Forks: What, Why, How
What are state forks, why can’t they happen but do anyway and how can they be resolved in OpenMLS?

Is anyone aware of any #typescript or #javascript implementation of MLS other than this seemingly abandoned one by the Matrix Foundation?
https://gitlab.matrix.org/matrix-org/mls-ts
Or do we just use a maintained Rust implementation like OpenMLS via WebAssembly?

When implementing cryptographic protocols, ensuring input validation is paramount. Neglecting this can lead to severe vulnerabilities.

When implementing cryptographic protocols, probably the most important thing is to not forget validating all inputs. Failing to do so can lead to inadvertant leakage of private information, state…

🥷 How XMTP defends against "Harvest Now, Decrypt Later"
Our partners at Cryspen have been working on a post-quantum OpenMLS, & have implemented hybrid ciphersuites that can be dropped in to replace all cryptography with post-quantum algorithms.
This now means no one can HNDL.

Thanks @expede.wtf!
There is a real tension in the community—that not everyone sees yet—between the desire to stick with MLS due to it being an IETF standard with open source reference libraries like OpenMLS, and the desire to use a protocol that doesn't introduce centralizing forces to ATproto.⚖️
