🛡️ Hash Generator

A data integrity tool that generates unique SHA-256 digital fingerprints for any text input.

Features

• Industry Standard: Uses the SHA-256 cryptographic algorithm.
• Integrity Checking: Demonstrates how even a minor change alters the entire output.
• Clean UI: Highlights the hash result in terminal green.

Usage

python hash_generator.py
