Why Choose This Project

Conventional messaging platforms often lack robust end-to-end encryption and can be vulnerable to interception. This project uses PGP (Pretty Good Privacy) to provide strong encryption for secure one-on-one or group chat, ensuring that only the intended recipient can read the messages. It’s an excellent choice to learn about asymmetric cryptography, secure key exchange, and real-world application of PGP.

What You Get in This Project

A fully functional, browser-based or cross-platform encrypted chat application where users generate their own PGP key pairs and exchange encrypted messages securely.

Technology Stack

How It Works

1. User Authentication
   Users register/login securely. Auth is required to ensure identity.

2. PGP Key Generation
   Each user generates their own PGP key pair (public + private). Private keys are stored encrypted locally or protected with a passphrase.

3. Key Exchange
   Public keys are exchanged between users and stored on the server or in a directory.

4. Encrypt Message
   When sending a message, it is encrypted using the recipient’s public key via OpenPGP.

5. Send via WebSocket
   Encrypted message is sent via WebSocket or REST API to the server.

6. Decrypt on Receiver End
   The recipient decrypts the message using their private key locally.

7. Secure Storage (Optional)
   Messages stored on the server remain encrypted.
