secure-network 1.0.9

A secure networking extension with authentication, HMAC, and encryption.

🔐 Secure Network

A powerful and flexible networking extension for Python with built-in authentication, encryption, and HMAC security.

---

🚀 Features

✅ Secure authentication with bcrypt and Multi-Factor Authentication (MFA).
✅ Encrypted communication using HMAC verification.
✅ Rate-limiting to prevent brute force attacks.
✅ Event-driven architecture for handling network interactions.
✅ Supports both authenticated and unauthenticated connections.

---

📦 Installation

Install Secure Network via PyPI:

pip install secure_network

⚡ Quick Start

1️⃣ Secure Authentication Server & Client

For authenticated connections, use the SERVER and CLIENT classes:

import secure_network

# 🔹 Initialize the server
server = secure_network.SERVER(
    key=None, hmac_key=None, 
    address=("0.0.0.0", 12345), 
    on_event=lambda event: print(event), 
    max_clients=10
)

# 🔹 Set the accounts file (default: accounts.json)
server.accounts_file = "accounts.json"

# 🔹 Create user accounts
server.create_account("admin", "adminpass", role="admin")
server.create_account("user", "userpass", role="user", mfa_method="email", contact="[e-mail]")

# 🔹 Initialize client
client = secure_network.CLIENT(
    key=None, hmac_key=None, 
    address=("127.0.0.1", 12345), 
    on_event=lambda event: print(event)
)

# 🚀 Start server and client
server.init()
client.init()

2️⃣ Basic Server & Client (Without Authentication)

If authentication isn't needed, use the Server and Client classes directly:

import secure_network

# 🔹 Initialize server
server = secure_network.Server(
    key=None, hmac_key=None, 
    address=("0.0.0.0", 12345), 
    on_event=lambda event: print(event), 
    max_clients=10
)

# 🔹 Initialize client
client = secure_network.Client(
    key=None, hmac_key=None, 
    address=("127.0.0.1", 12345), 
    on_event=lambda event: print(event)
)

# 🚀 Start server and client
server.init()
client.init()

🎯 Handling Events

Events provide real-time feedback about network status. You can handle them like this:

import secure_network

def on_event(event: secure_network.Event):
    if event.type == secure_network.EventType.CONNECTION_REQUEST:
        event.accept()  # ✅ Accept connection
    elif event.type == secure_network.EventType.CONNECTION_SUCCESS:
        print(f"✅ Client connected: {event.data['address']}")
    elif event.type == secure_network.EventType.RECEIVED:
        print(f"📩 Received data: {event.data['data']}")
    else:
        print(f"ℹ️ Event: {event.type.id} - {event.type.description}")

# Generate secure keys
KEY, HMAC_KEY = secure_network.generate_key(), secure_network.generate_hmac_key() 

# Create server
server = secure_network.Server(
    key=KEY, hmac_key=HMAC_KEY, 
    address=("0.0.0.0", 12345), 
    on_event=on_event, 
    max_clients=10
)

# 🚀 Start server
server.init()

# Keep server running
while server.active:
    pass

🔥 Event Types

Secure Network provides several event types for handling different network interactions:

Event Type	Description	Data Fields
CONNECTION_REQUEST	Someone is trying to connect	{address, connection} (can accept/reject)
CONNECTION_SUCCESS	A client has successfully connected	{address, connection}
CONNECTED	The client/server has started communication	{}
DISCONNECTED	A client/server has disconnected	{}
RECEIVED	Data received from a device	{address, connection, data}
THREAD_WARNING	A thread did not behave as expected	{thread}
ERROR	An error occurred	{exception}

ℹ️ Additional Information

• event.data contains event-specific details (e.g., client address, message data).
• event.accept() and event.reject() can be used for CONNECTION_REQUEST events.
• Addresses and connections appear only on the server side (clients do not see them).
