I’ve always been a big fan of understanding the basics of infosec to help your career in the long run. Fitting that this past weekend I came across a great little 5 minute video explaining how public key cryptography works in terms of the Diffie-Hellman Key Exchange. Thanks to @rgaucher for retweeting this awesome piece.

It starts out with a simple paint-mixing analogy and then heads into the heart of the matter explaining it in mathematical terms with moduluses, logarithms, and all that. Enjoy!
At the end of the video they also mention a forthcoming RSA version. I’d watch out for that as well. See ya! This post’s image is from Quora.com.
