Note in particular that the current system does not have forward secrecy. Near the end of the post: > Then we plan to launch a 'Whisper Mode' for additional protection when in instant messaging sessions (e.g. message transcript/order consistency, delivery assurance, forward secrecy, and some others). This is what I was working on at MEGA, but recently they decided to stop funding me, and I'm under the strong impression that nobody else there is working on this. So it's unclear that they have a concrete time frame for it. The source code and docs are here though: https://github.com/meganz/mpenc_js https://github.com/meganz/mpenc_js https://github.com/meganz/mpenc_doc https://github.com/meganz/mpenc_doc https://docs.mega.nz/chat/mpenc/ https://docs.mega.nz/chat/mpenc/ If anyone wants to continue funding this work, feel free to drop me a line.
