BB84 Quantum Encryption Tool Simulator: BB84 Quantum Hybrid Encryption – Prototype v1.1

This is the first official release of the BB84 Quantum Hybrid Encryption Tool – a scientific prototype implementing quantum-classical encryption techniques for secure file exchange.

🔐 Key Features:

• BB84 Quantum Key Distribution (QKD) simulation using Qiskit (AerSimulator).
• AES-256 encryption in CBC mode with secure key embedding.
• HMAC-SHA256 for integrity verification between Key A and Key B.
• Optional Dilithium2 digital signature (NIST PQC standard).
• Secure .bb84 file packaging with GUI (Tkinter-based).
• Scientific metric logging and test validation support.

📁 What's included:

• Full Python source code and modular architecture.
• GUI interface, encryption/decryption logic, metrics module.
• Sample test file and metric output examples.

🔬 Research Context: This prototype was developed as part of a hybrid quantum-classical cryptography project aiming to simulate post-quantum secure communication channels. It demonstrates a novel architecture combining quantum key distribution and classical cryptographic robustness.

🆕 What's new in v1.1:

• Minor improvements and packaging adjustments.  
• Cleaned file structure and clarified interface documentation.  
• Description and metadata updated for version consistency.
