💬 Message aux apprenants

{'encouragement': "You're learning about the only encryption method with security guaranteed by the laws of physics. While classical encryption could theoretically be broken, quantum cryptography is secure forever.", 'reminder': "QKD is already commercial and deployed worldwide. This isn't science fiction - it's protecting secrets right now.", 'action': 'Run the BB84 protocol in the simulator. Try eavesdropping and see how you get caught. Understand why physics beats mathematics for security.', 'dream': 'A cryptographer from Kenya might develop new QKD protocols. A physicist from Nigeria might solve the quantum repeater challenge. Quantum security should protect everyone, everywhere.', 'wiaVision': 'WIA Pin Code believes that understanding unbreakable security should be accessible to all. Quantum cryptography protects privacy as a fundamental right.'}
