🛠 Technology Stack

• Frontend: React.js, TailwindCSS
• Backend & Database: ConvexDB
• Encryption: RSA
• Hashing: Blowfish Cipher

🔐 How It Works

1. User Registration

   • Generate unique RSA key pairs
   • Store public key on server
   • Keep private key secure on client-side

2. Secure Messaging

   • Encrypt messages with recipient's public key
   • Only recipient can decrypt with their private key
   • Automatic message deletion after 1 minute

Installation Steps

1. Clone the Repository

   git clone https://github.com/yourusername/wispyr.git
   cd wispyr

2. Configure Environment Create a .env file with the following:

   # Deployment used by npx convex dev
   AUTH_SECRET=your_auth_secret
   CONVEX_DEPLOYMENT=your_convex_deployment
   NEXT_PUBLIC_CONVEX_URL=your_convex_url

3. Run the Application

   # Start Convex
   npx convex dev
   
   # Run Backend
   cd backend
   npm start
   
   # Run Frontend
   cd ../frontend
   npm run dev

🔒 Encryption Technical Overview

Key Generation

const { publicKey, privateKey } = generateKeyPair();

Message Encryption

const encryptedMessage = encryptWithPublicKey(message, recipientPublicKey);

Message Decryption

const decryptedMessage = decryptWithPrivateKey(encryptedMessage, recipientPrivateKey);
