# The Unknow

The Unknow is a secure communication system developed by Trapzzy. It uses symmetric encryption to ensure that messages sent between a client and a server are encrypted and secure. The system also employs HTTPS to provide a secure channel for communication over the internet.

## Features

- Symmetric encryption using Fernet (AES)
- Secure communication over HTTPS
- Multi-threaded server to handle multiple clients
- User-friendly client interface for entering the server link

## Requirements

- Python 3.6 or higher
- `cryptography` library
- OpenSSL (for generating self-signed SSL certificates)

## Setup

1. **Install the required Python library**:

   ```bash
   pip install cryptography

2. Generate a self-signed SSL certificate (for testing purposes):

   openssl req -x509 -newkey rsa:4096 -keyout server.key -out server.crt -days 365 -nodes

   This will create server.crt and server.key files in your current directory.

3. Run the server:

   python server.py

   The server will display a link for secure communication. Note this link for use in the client.

4. Run the client:

   In a separate terminal or on a different machine, run:

   python client.py

   Enter the link displayed by the server when prompted.

Usage

Once the server and client are running, the client can send encrypted messages to the server. The server will decrypt these messages and display them.

Security

• The system uses Fernet symmetric encryption, which is built on top of AES.
• Communication between the client and server is encrypted using HTTPS.
• For production use, obtain a certificate from a trusted certificate authority (CA) instead of using a self-signed certificate.
