Diffie-Hellman key exchange is the foundation of how two parties agree on a shared secret over a channel someone else might be watching. The Key Exchange simulator walks through it step by step.

What this tool does

  • Simulates a Diffie-Hellman key exchange between two parties
  • Shows each mathematical step of establishing a shared secret

How to use it

  1. Open the Key Exchange tool.
  2. Enter or generate the exchange parameters.
  3. Follow the step-by-step simulation of the key exchange.

Common use cases

  • Learning how public key cryptography establishes a shared secret
  • Teaching the concept behind HTTPS and secure connections

FAQ

Is this the actual algorithm used in HTTPS?

Diffie-Hellman and its variants underpin key exchange in many real-world protocols including TLS, this simulator demonstrates the same core mathematical concept.
