   An Elliptic Curve-Based Secure Chat, Written Using Rust and Protobuf▲66

   This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

    faces.io – ridiculously simple video chat▲40

It’s definitely beta status at best. Audio can get weird—be ready to mute. ;-) Let me know what you think!
