About this video
The Diffie-Hellman protocol is the underpinning of so many other security protocols on the Internet. It's the most popular answer to the question: How do we establish a shared key over an unsecure wire?
Diffie-Hellman uses a sequence of math calculations to answer that question. And in this video I'm going to prove it to you.
This lesson is a free sample lesson from the the greatest TLS and SSL training course ever created. No instructor rambling on about pointless stories. No slides with massive walls of text. No time wasting. Only simple, effective, and precise explanations. Complimented with practical illustrations and visuals.
