We just pushed the newest update, 0.5.0, which finally brings Post-Quantum-Crypto (PQXDH) to twonly. For this we use libsignal [1], which is Signal's library used also in their apps. Currently this is only for new chats, but in the next releases we will update all chats to use PQXDH. [1]: https://github.com/signalapp/libsignal #e2ee #privacy #security #signal #snapchat
