Top 3 double-ratchet Open-Source Projects

simplex-chat

247 5,328 9.9 Haskell

SimpleX - the first messaging network operating without user identifiers of any kind - 100% private by design! iOS, Android and desktop apps 📱!

Project mention: What are your favorite End-to-End encrypted tools for online privacy? | /r/degoogle | 2023-12-08

For messaging I'm currently on Olvid (E2E with physical key exchange) but since it still use their servers, I'm currently testing SimpleX where I can host my own servers.

vodozemac

1 118 8.5 Rust

An implementation of Olm and Megolm in pure Rust.

Project mention: Telegram has launched a pretty intense campaign to malign Signal as insecure | news.ycombinator.com | 2024-05-13

Would make more sense if it is reproducible builds. Shouldn't we just all switch to matrix clients which use Olm and Megolm cryptographic ratchets and it doesn't rely on one server/one entity.
And looks like it is implemented in Rust:
