Crypto Football Game

Crypto Football Game is a secure, interactive football management simulation written in Python. This project combines the excitement of building your dream football team with the power of modern cryptography, offering a unique experience for football fans, students, and security enthusiasts alike.

Features

• Secure Registration & Login
  User accounts are protected with strong password requirements, secure token generation, and encrypted credentials.

• Encrypted Data Storage
  All sensitive information—user data, team rosters, and transaction records—is encrypted using cutting-edge cryptographic algorithms.

• Digital Certificate Authentication
  The system leverages a certificate authority hierarchy (root, intermediate, client/server certificates) to validate all critical communications and in-game transactions.

• Football Transfer Market
  Buy and sell real-world football stars in a secure, randomised marketplace. Every transaction is encrypted and authenticated.

• Team Management
  Build your football dream team, monitor your balance, and manage your squad through a simple command-line interface.

• Session Key Exchange
  All in-game actions and sensitive operations are protected via session-based symmetric encryption, ensuring privacy and integrity.

Why Crypto Football Game?

• Demonstrates real-world security best practices in a fun, educational setting.
• Perfect for learning about cryptography, certificate-based authentication, and secure application development.
• Engages football fans with interactive, risk-free team building and trading.
