Diffie–Hellman Key Exchange Explained – Mathematics, Security & Real-World Usage

Diffie–Hellman was the first practical public key key-exchange protocol. It allows two parties to create a shared secret over an insecure channel.

In this video, we cover:

• The key exchange problem
• Mathematical foundation
• Modular exponentiation
• Primitive roots
• Discrete logarithm problem
• Step-by-step Diffie–Hellman
• Why it works
• Security intuition
• Man-in-the-middle attack
• Ephemeral DH and forward secrecy
• Elliptic Curve Diffie–Hellman (ECDH)

This is a complete conceptual breakdown for serious learners.
