The Diffie Hellman key exchange is one of the most important developments in public-key cryptography. It is extensively used by many common protocols to securely exchange a symmetric key over an insecure channel - like the internet.

Amazing videos as always. Would wish if you cover Cloud topics

@destcert 2 жыл бұрын

We are going to start covering more cloud topics aligned with the CCSP classes we teach. What specifically would you like us to cover?

@tayyar07 2 жыл бұрын

@@destcert Topics that would explain the CCSP domains. Similar to what has been done for the CISSP. It could be Cloud architecture, Data security in the cloud. Keep up the good work 👍🏻

Thank you guys. Enjoyed so much. So grateful for your great work. Wondering why it is so that Diffie Helman needs to be used whilst RSA can also exchange key of a symmetric algorithm securely......need some homework for it. Thank you guys. 😊

This was a nice explanation. I love cryptography (makes math interesting). Reading a great book called "the Mathematics of secrets" right now... awesome, if you have time and are a cryptography fan, you will like it. Oh, since you may be reading this, thanks for all the videos you have made... helped me with my CISSP last year!

Same - watched all of these wonderfully balanced videos as a complement to my CISSP prep as well. Thanks for the learning methods and content.
