A new secure messenger needs to have a solid foundation. For Air, this foundation is OpenMLS. It has been years in the making, and now it has been audited. This is an important milestone for Air.
Air@air.ms · 2mo agoIt’s still early days for Air, but the foundation on which it is built is solid. The @sovereign.tech funded a security audit conducted by @srlabs.bsky.social of the underlying end-to-end encryption.
The OpenMLS audit report is now public!

We made MLS more decentralized! We are excited to share DMLS that brings fork resilience to the MLS protocol, solving a key challenge in distributed systems while maintaining Forward Secrecy. This work was made possible by @equalitie.bsky.social, who funded it as part of the Breakout program.

There's an article making the rounds with the provocative title "MLS: The Naked King of End-to-End Encryption". It needs some rebuttal. www.poberezkin.com/posts/2025-0... tl;dr - MLS is fine. This is a misunderstanding about modularity.

Not long ago, someone (who is likely the founder of SimpleX Chat) wrote a blog post about MLS that contained a pretty blatant factual mistake about MLS' authentication, including an alleged lack of security. Thankfully, @soatok.bsky.social took the time to debunk that: soatok.blog/2025/08/25/b...

Happy to announce that I’ll be speaking at @passthesaltcon.bsky.social on July 2nd! I’ll discuss end-to-end encryption with MLS, the growing MLS ecosystem, the MIMI IETF working group, and metadata protection. It’s my first time attending, and I look forward to connecting with the French community!
The idea that you can just “teach computer science” and be apolitical is a beautiful dream that expired in the 2000s, at the latest. Computer science has re-organized every facet of our society: it is inherently political. Instead of taking this idea seriously, we ran from it. Now we live in hell.
