✨ Overview

Evrmore Authentication is a Python package that provides wallet-based authentication using Evrmore signature verification. This allows users to authenticate to web applications using their Evrmore wallet without sharing their private keys, creating a secure and user-friendly authentication experience.

Key Features:

• 🔑 Wallet-based authentication - Users sign a challenge message with their Evrmore wallet
• 🔒 JWT token management - Secure session handling with JSON Web Tokens
• 📁 SQLite backend - Simple, file-based database for session and challenge storage
• 👤 Automatic user management - Users are created on first authentication
• 🌐 Complete API server - Ready-to-use FastAPI server for authentication endpoints
• 🖥️ Demo web interface - Example Flask application showing the complete authentication flow

🚀 Quick Start

Installation

pip3 install evrmore-authentication

Running the API Server

python3 -m scripts.run_api_server --host 0.0.0.0 --port 8000

Running the Web Demo

python3 -m scripts.run_web_demo --port 5000 --api-url http://localhost:8000

🧰 System Requirements

• Python 3.7 or higher
• SQLite database for session and challenge storage
• Evrmore node (for signature verification)

🔐 Authentication Flow

📘 Usage in Your Application

Basic Authentication Flow

from evrmore_authentication import EvrmoreAuth
from evrmore_rpc import EvrmoreClient

# Initialize the authentication system with an Evrmore client
client = EvrmoreClient()
auth = EvrmoreAuth(client)

# Generate a challenge for a user's Evrmore address
challenge = auth.generate_challenge("EXaMPLeEvRMoReAddResS")

# Verify the signature provided by the user
session = auth.authenticate(
    evrmore_address="EXaMPLeEvRMoReAddResS",
    challenge=challenge,
    signature="signed_challenge_from_wallet"
)

# Use the token for authentication
token = session.token

# Validate a token
token_data = auth.validate_token(token)

# Get user from token
user = auth.get_user_by_token(token)

# Invalidate a token (logout)
auth.invalidate_token(token)

FastAPI Integration

The package includes a ready-to-use FastAPI server with the following endpoints:

⚙️ Configuration

Configuration is done through environment variables or a .env file:

# SQLite configuration
SQLITE_DB_PATH=./data/evrmore_auth.db

# JWT configuration
JWT_SECRET=your-secure-secret-key
JWT_ALGORITHM=HS256
JWT_ACCESS_TOKEN_EXPIRE_MINUTES=30

# Challenge configuration
CHALLENGE_EXPIRE_MINUTES=10
