🔑 Nostr Vanity Key Generator

A demonstration web application for generating Nostr cryptographic key pairs with custom prefixes. Generate proof-of-work public keys or vanity public keys with specific patterns using client-side cryptography.

🌐 Try it live at nostr.rest

✨ Features

• 🔒 Client-Side Generation: All key generation happens locally in your browser - no data is sent to external servers
• 🎯 Custom Prefixes: Generate keys with specific hex prefixes (e.g., be, dead, cafe)
• ⚡ Dual Speed Modes: Choose between slow mode (browser-friendly) and fast mode (maximum performance)
• 📱 Mobile Responsive: Optimized interface for both desktop and mobile devices
• 🛡️ Privacy First: Disconnect from the internet before generation for maximum privacy
• 📊 Real-Time Progress: Live updates showing generation progress and statistics

🎮 How It Works

1. Enter a Prefix: Type your desired hex prefix (e.g., be, dead, cafe)
2. Choose Speed Mode: Slow mode for stability, fast mode for maximum speed
3. Generate: Watch as the tool searches for a matching key pair
4. Copy Keys: Use the copy buttons to save your generated keys

Prefix Rules: Only use hexadecimal characters (0123456789abcdef). Longer prefixes take exponentially more time to generate.

🛠️ Technical Details

Built with Next.js, Material-UI, and nostr-tools for client-side cryptography. This is a single-threaded implementation designed for demonstration purposes.

For production vanity key generation with larger prefixes, consider using Rana for multi-threaded generation.
