SecureChat Realtime Chat App with real time end to end endcritption ✨
# ✨ Full
# 🔐 SecureChat – End-to-End Encrypted Messaging App
SecureChat is a modern full-stack chat application built with security and privacy at its core. Using cutting-edge **end-to-end encryption (E2EE)**, SecureChat ensures that messages can only be read by the intended recipients — not even the server can decrypt them.
---
## 🚀 Features
- 🔐 **End-to-End Encryption (E2EE)** using **RSA + AES Hybrid Encryption**
- 🧑🤝🧑 Real-time 1:1 messaging
- 🖼️ Send text and image messages
- 🟢 Online/offline presence indicator
- 🔒 Secure key generation and exchange per user
- 🗑️ Ephemeral message keys – no permanent storage of private keys
- 🧠 Smart error handling and toast notifications
- 🌐 Cross-browser and responsive UI
---
## 🧰 Tech Stack
**Frontend:**
- React.js + Tailwind CSS
- Zustand (for global state management)
- CryptoJS (for frontend encryption logic)
**Backend:**
- Node.js + Express
- MongoDB with Mongoose
- Cloudinary (for image storage)
- JSON Web Tokens (JWT) for authentication
- IndexedDB (for local private key storage in browser)
**Security:**
- RSA (asymmetric encryption) for secure key exchange
- AES (symmetric encryption) for efficient message encryption
- Per-user public/private key generation
- End-to-end encryption handled entirely on the client-side
