simes: Simple Encrypted Socket Library

Overview

simes is a Python library designed to facilitate secure and easy-to-use encrypted communication over sockets. It provides a suite of tools for encrypting and decrypting messages sent over TCP/IP, ensuring that your data remains private and secure during transmission.

Features

• AES Encryption: Utilizes Advanced Encryption Standard (AES) in CBC mode for strong encryption.
• Automatic Padding: Handles padding of messages to fit block size requirements.
• IV Management: Securely generates and manages Initialization Vectors (IVs) for each encryption operation.
• Key Management: Offers a simple interface for managing encryption keys.
• Error Handling: Robust error handling for common issues like message size limits and unknown senders.
• Socket Communication: Seamlessly integrates with Python's socket module for network communications.

Installation

To install simes, you can simply use pip:

pip install simes

Usage

Here's a quick example to get you started with simes:

Encrypting and Sending a Message

import socket
from simes import sendEncryptedJSON

# Setup socket and key
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
key = b'secret_key_16_byte'

# Encrypt and send a message
data = {"message": "Hello, World!"}
sendEncryptedJSON(sock, 'sender_name', data, key)

Receiving and Decrypting a Message

from simes import receiveEncryptedJSON

# Assuming 'sock' is a socket object

keys_dict	= {'sender_name': b'secret_key_16_byte'}

sender, data = receiveEncryptedJSON(sock, keys_dict)
print("Received message from", sender, ":" data)
