Hybrid Classical + Post-Quantum Cryptography Explained

Hybrid cryptography combines classical algorithms like ECDH or RSA with post-quantum algorithms like CRYSTALS-Kyber and Dilithium.

In this video, we cover:

• Why we cannot switch directly to PQC
• The migration problem
• Hybrid key exchange
• Hybrid digital signatures
• TLS hybrid handshake
• Security reasoning
• Failure scenarios
• Real-world deployment strategies

This video explains how the internet will safely transition into the post-quantum era.
