- 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.

Hope your channel gets more engagement! You deserve it!
I really like the quality of content u make guys. Thanks for existing!
These videos absolutely kick ass. Thanks for your videos on the CISSP.
underrated channel!!!
Thank you!
Fascinating stuff Rob, have missed your content. I Luv it
absolutely fantastic video, thank you for the clear refreshing course on DH key exchange, Rob
Amazing video with awesome content. Thanks a lot Rob.
Amazing videos as always.
Would wish if you cover Cloud topics
We are going to start covering more cloud topics aligned with the CCSP classes we teach. What specifically would you like us to cover?
@@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. 😊
Our pleasure!
Have you found an answer to this yet as it is bugging me as well?
Finally we meet Bob from Alice and Bob who are always sharing keys lol
Eleptic curve, rsa, 3des, des , its good to have all of that.. thanks Destination certification... 😊
When are you guys coming back to do more video? These are great.
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.
🙌
Thank you.
Please cover all the topics of CISSP 😍
*50 years later* Annnnd we did it!
50 years seems a bit quick, but we'll endeavour to get it done in that short period of time 😜
Practicly impossible for supercomputers yet invented by human creative mind by applying logic and imagination. Amazing!
