# IPFSChat
IPFSChat is a decentralized chat application built on the InterPlanetary File System (IPFS) using Go. It leverages IPFS
PubSub for message distribution and Diffie-Hellman key exchange for secure communication.
## Features
- Decentralized messaging using IPFS PubSub
- Secure communication with Diffie-Hellman key exchange
- AES-GCM encryption for message confidentiality
- Terminal-based user interface with `tview` and `tcell`
## Requirements
- Go 1.16+
- IPFS node with pubsub
## Installation
1. Clone the repository:
```sh
git clone https://github.com/d6o/ipfschat.git
cd ipfschat
```
2. Install dependencies:
```sh
go mod tidy
```
3. Run the application:
```sh
go run main.go
```
Replace `` with the desired chat topic.
## Usage
1. Start your IPFS daemon:
```sh
ipfs daemon
```
2. Run the IPFSChat application with a topic of your choice:
```sh
go run main.go mytopic
```
3. Use the terminal interface to send and receive messages securely.
## Code Overview
The main components of IPFSChat include:
- **DHKey Exchange**: Uses the `dhkx` library for Diffie-Hellman key exchange to establish shared secrets with peers.
- **IPFS PubSub**: Utilizes the IPFS PubSub system to publish and subscribe to messages on a specified topic.
- **Encryption**: Messages are encrypted with AES-GCM using the shared secret derived from the Diffie-Hellman exchange.
- **Terminal UI**: The user interface is built using `tview` and `tcell`, providing a text-based UI for interaction.
