WhiteNoise CLI - Interactive Secure Messaging

FULLY VIBED AND EXTREMELY EXPERIMENTAL

A command-line interface for secure messaging using the WhiteNoise protocol (Nostr + MLS), fully compatible with the WhiteNoise Flutter client.

Features

• 🔐 Secure Identity Management: Generate and manage cryptographic identities with MLS credentials
• 👥 Contact Management: Add, list, and remove contacts with metadata support
• 💬 MLS-based Messaging: Direct messages and group chats using MLS encryption
• 🤖 Automation Support: Full CLI mode for scripting and automation
• 📱 Flutter Compatible: 100% compatible with WhiteNoise Flutter client
• 🔄 Multi-Relay Support: Nostr, Inbox, and KeyPackage relay types
• 💾 Persistent Storage: WhiteNoise database for account persistence

Installation & Setup

1. Install Rust (if not already installed):

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   source ~/.cargo/env
   

2. Build the project:

   cargo build --release
   

   Note: Requires Rust 1.82+ for async trait support

3. Run the CLI:

   # Interactive mode
   cargo run
   
   # CLI mode (see CLI Commands section)
   cargo run -- --help
   

Usage

Interactive Mode

Run without arguments to enter interactive mode with menus.

CLI Mode

Use command-line arguments for automation:

# Create account with profile
./whitenoise-cli account create --name "Alice" --about "Decentralized messaging fan"

# Send direct message (creates MLS DM group)
./whitenoise-cli message dm --recipient <pubkey> --message "Hello!"

# Create group chat
./whitenoise-cli group create --name "My Group" --members "pubkey1,pubkey2,pubkey3"

# Send group message
./whitenoise-cli message send --group-id <group_id> --message "Hello group!"

Main Menu Options (Interactive Mode)

1. 💬 Start Conversation

   • Select from your contacts
   • Chat in real-time with a secure interface
   • Type messages and press Enter to send
   • Type 'quit' or press Enter on empty input to exit chat

2. 👥 Manage Contacts

   • ➕ Add New Contact: Add contacts by name and public key
   • 📋 List All Contacts: View all your contacts
   • 🗑️ Remove Contact: Remove contacts from your list

3. 🔑 Identity Settings

   • 📝 Change Name: Update your display name
   • 📋 Copy Public Key: View and copy your public key to share
   • 🔄 Generate New Identity: Create a new identity (warning: loses access to existing conversations)

4. ❌ Exit: Quit the application

Chat Interface

• View recent message history
• Send messages in real-time
• Messages show timestamps and sender names
• Clean, colorful interface with proper formatting

Data Storage

The CLI stores data locally in your system's data directory:

• Identity: ~/.local/share/whitenoise-cli/identity.json
• Contacts: ~/.local/share/whitenoise-cli/contacts.json

Technical Details

• Built with Rust for performance and safety
• Nostr SDK for cryptographic operations
• Interactive CLI using dialoguer for menus and input
• Async/await support with Tokio runtime
• JSON serialization for data persistence
• Colorful terminal output with console styling

Demo Scripts

The repository includes comprehensive demo scripts to showcase CLI-Flutter compatibility:

Running the Full Demo

# Run the complete demo (creates profiles, exchanges messages, creates group chat)
./demo_auto_conversation.sh

This demo will:

1. Create Alice and Bob accounts with profiles
2. Exchange MLS-based direct messages
3. Create a group chat with Alice, Bob, and a third member
4. Post messages in the group chat
5. Export Flutter-compatible private keys for import

Individual Setup Scripts

# Set up Alice
./alice_setup.sh

# Set up Bob (in another terminal/directory)
./bob_setup.sh

Verifying Messages on Relays

Install nak to verify events:

# Check Alice's messages
nak req -k 4 --author <alice_pubkey> --limit 10 wss://relay.damus.io

# Monitor live messages
nak req -k 4 --author <alice_pubkey> --author <bob_pubkey> --stream wss://relay.damus.io

Current Status

This is a fully functional implementation of the WhiteNoise protocol:

• ✅ MLS-based secure messaging (not NIP-04)
• ✅ Direct messages using MLS groups (Flutter compatible)
• ✅ Group chat support with MLS encryption
• ✅ Full relay support (Nostr, Inbox, KeyPackage)
• ✅ Account persistence via WhiteNoise database
• ✅ CLI automation support
• ✅ 100% Flutter client compatibility
