## Ad hoc E2E Encrypted Group Chat

### What

This project is a fully functional, minimalist, ad hoc, end-to-end encrypted web group chat. It uses websocket for all message delivery which is more reliable than WebRTC.

### Why

At times, there's a need for private, anonymous group chats. Many existing applications with end-to-end encryption are overly complex. Conversely, simpler applications lack both end-to-end encryption and group functionality. Hence, I invested a few days to develop one myself. It primarily serves as a proof of concept.

### How

The backend is implemented using WebSockets written in Golang. I made minimal modifications based on https://github.com/madeindra/golang-websocket

On the client side, I opted for handwritten, plain JavaScript, avoiding the use of complex frameworks.

### Demo

### Alternative

* [My 1-on-1 e2e encryption chat using piping server](https://privapps.github.io/share/chat)

* [My 1-on-1 WebRTC chat with file sharing](https://privapps.github.io/share/)

For a more completed robusted solution, I would recommand to use [Ergo](https://github.com/ergochat/ergo) as backend and [Kiwi](https://kiwiirc.com/) as front end. A low end 100 MB RAM server can handle thousands of users.
