Diffie-Hellman Key Exchange
Visualize the Diffie-Hellman key exchange protocol step by step.
Public Parameters
This tool simulates the Diffie-Hellman key exchange - a foundational cryptographic method that lets two parties agree on a shared secret key over an insecure channel, without ever transmitting the key itself. It's an educational visualization of how the math behind this widely-used protocol actually works, step by step.
Frequently asked questions
This is an educational simulation meant to illustrate how the Diffie-Hellman math works conceptually - it's not intended to generate or exchange a real production-grade secret key for an actual secure communication channel.
It's a core building block in many real-world security protocols (like TLS/HTTPS) that lets two parties establish a shared secret key over a public network without ever sending the key itself, protecting against eavesdroppers.
The tool is designed to visualize the process step by step, making the core idea (public math operations that produce a shared secret only the two parties can compute) approachable even without deep prior cryptography knowledge.
