Symmetric keys are essential to encrypting messages. How can two people share the same key without someone else getting a hold of it? Upfront asymmetric encryption is one way, but another is Diffie-Hellman key exchange. This is part 3 in our Cryptography 101 series. Check out the playlist here for parts 1 & 2: youtube.com/watch?v=NOs34_-eREk&list=PLa6IE8XPP_gmVt-Q4ldHi56mYsBuOg2Qw

Symmetric single-key encryption schemes have become the workhorses of secure communication for a good reason. Theyâre fast and practically bulletproof⌠once two parties like Alice and Bob have a single shared key in hand. And thatâs the challenge -- they canât use symmetric key encryption to share the original symmetric key, so how do they get started?
