🏰 NIP-46 Remote Signer (Bunker) Test Setup

This directory contains a complete NIP-46 remote signing setup for testing NOSTR_LOGIN_LITE.

🔧 Setup Overview

Bunker: A remote signer daemon that holds your private keys securely Client: Browser client that connects to the bunker to request signatures NOSTR_LOGIN_LITE: Connects to bunker for remote signing capability

🔑 Generated Keys

Bunker Secret Key: a33767c3bd05bda47880119d6665b79e6f0eecdf8d025966b0b59a9366379d01
Bunker Public Key: 7566048aa9df5b36428f2ce364797f7ac6f6d4a17ee566f0cd3fefcf35146b90

🚀 Testing NIP-46 Remote Signing

Step 1: Start the Bunker

# Open a new terminal and run:
./nip46-test/start-bunker.sh

You'll see output like:

🔐 Starting NIP-46 Bunker Remote Signer...
==============================================
Bunker Public Key: 7566048aa9df5b36428f2ce364797f7ac6f6d4a17ee566f0cd3fefcf35146b90
Secret key is securely held by bunker

🚀 Starting bunker daemon...
{"time":"202X-XX-XXTXX:XX:XX.XXXZ","level":"info","msg":"starting bunker on ws://localhost:8080"}
{"time":"202X-XX-XXTXX:XX:XX.XXXZ","level":"info","msg":"bunker ready to handle NIP-46 requests"}

Step 2: Test with NOSTR_LOGIN_LITE

Navigate to:

http://localhost:8000/examples/modal-login-demo.html

Click "🚀 Launch Authentication Modal" and select "NIP-46 Remote" option.

The browser will connect to the bunker running on ws://localhost:8080 and request signatures remotely.

🔄 How NIP-46 Works

Browser (NOSTR_LOGIN_LITE) → WebSocket → Bunker (NAK on localhost:8080)
     ↓                                                   ↓
   Requests signature                      Holds private key
     ↓                                                   ↓
   Receives signed event                   Signs & returns result

🧪 Testing Scenarios

✅ Successful Connection

• Bunker runs on localhost:8080
• Browser connects and requests pubkey
• Bunker responds with 7566048aa9df5b36428f2ce364797f7ac6f6d4a17ee566f0cd3fefcf35146b90

🔧 Signature Requests

• Browser sends event to sign
• Bunker signs with private key
• Signed event returned to browser
• Browser publishes signed event to relay

🐛 Debug Issues

• Check bunker logs for connection errors
• Verify WebSocket connection in browser dev tools
• Look for NIP-46 protocol errors

📝 NOSTR_LOGIN_LITE Configuration

In your app, configure remote signing like this:

const nip46Config = {
  type: "nip46",
  bunker: {
    pubkey: "7566048aa9df5b36428f2ce364797f7ac6f6d4a17ee566f0cd3fefcf35146b90",
    url: "ws://your-bunker-server:8080"  // Production URL
  }
};

await window.NOSTR_LOGIN_LITE.init(nip46Config);

⚠️ Production Notes

• This setup uses localhost - replace with real server URL in production
• Private key is shown for testing - production bunkers should be secured
• WebSocket URL should be secure (wss://) in production
• Consider authentication for your bunker to prevent unauthorized access

🎯 Common Testing Commands

Check NAK version

nak --version

Generate new keys (if needed)

nak key generate  # Secret key
echo "your_secret_key_here" | nak key public  # Public key

Manual bunker test

nak bunker --sec "your_secret_key" --port 8080 --relay "wss://relay.damus.io"

🐛 Troubleshooting

Bunker won't start:

• Check if port 8080 is free
• Verify NAK is installed correctly

Browser can't connect:

• Check firewall settings
• Verify bunker is running (ps aux | grep nak)
• Check browser console for WebSocket errors

Signing fails:

• Verify keys are correct
• Check bunker logs for errors
• Ensure event format is valid
