Diffie-Hellman Key Exchange
Art of the Problem · 9 recommenders · 8 months
A short explainer on the history and mechanics of public key cryptography and the Diffie-Hellman key exchange. It uses a mixing-paint-colors analogy to show how two parties can agree on a shared secret in public.
Why Hacker News readers recommend it: It is the go-to beginner explanation of Diffie-Hellman, recommended because the paint analogy makes the idea click without prior cryptography knowledge.
