WebAug 11, 2024 · The Big Picture. Diffie-Hellman key exchange is a way that two or more people can arrive at the same cryptographic key in a secure way. It may help to think of it as a negotiation rather than an exchange — the parties involved never exchange the shared cryptographic key itself, but instead follow a certain protocol in order to arrive at it ...
