https://github.com/cpscript/ecdh-chat-application

A extremely simple chat client made in HASKELL that uses the "Elliptic Curve Diffie-Hellman (ECDH) key exchange protocol" to establish a secure connection between two users. This is a one file script that includes a server and a user client and allows multiple users to message secrets using SHA-256 and AES-256 for encription and decryption.

## Features

* Secure key exchange using ECDH protocol

* Symmetric encryption using AES-256

* Simple chat interface for sending and receiving messages

## Requirements

* Haskell compiler (e.g. GHC)

* `crypto` and `network` libraries

## Usage

1. Compile the code using `ghc ECDHChat.hs`

2. Run the server using `./ECDHChat server`

3. Run the client using `./ECDHChat client`

4. Follow the prompts to enter your username and the server's username

5. Send and receive messages securely using the chat interface

## Warnings:

> * This is a basic implementation and does not include any error handling or security measures beyond the ECDH key exchange protocol... Sorry <3

> * The application uses a simple symmetric encryption scheme and does not provide any authentication or authorization mechanisms.

> * This code is for educational purposes only and should not be used in production without further development and testing.
