TLS Handshake Deep Dive and decryption with Wireshark

Warning! We go deep in this video to explain how the TLS handshake is completed. Warning! This is a technical deep dive and covers a lot of detail including SSL decryption and discusses RSA, Public and Private Keys, symmetric key exchange and lots more.

David! It was a ton of fun doing this video with you! Thanks for the opportunity! I love sharing some of the wonders of the SSL and TLS protocols =). Cheers!

[Noobinski]

OMG! After 25 years I finally got my head around how those handshakes work and how security is done. Thank you very much, gentlemen!

[stepankarel]

Awesome to see Ed on your channel, he is without any doubt one of the best networking teachers I came accross. Especially him and Jeremy helped me a lot in passing my CCNA - actually just today!

[kylechavez]

David this type of content is amazing. I am loving these deep dives you are doing with other SMEs. This content is extremely helpful and I greatly appreciate you working out offer code deals to get content from the SMEs at a discount. Just purchased Ed’s TLS course and Chris’ wireshark course. Super excited to go through both of them! Keep these deep dives coming, the real world examples and the heavy usage of wireshark packet captures to demonstrate what is actually happening is VERY helpful. There are lots of resources online and offline with all the basics, I appreciate you diving into how things really work so we can get a better foundation to design and troubleshoot from. Keep this up, I’m looking forward to more protocols and more deep dives!

[Alain-]

thank you so much for the quality I've never missed these long version video

[balajichowdary]

Thank you very much David for having Ed from practical networking on your show.I am very delighted to see him with you

[dwaynesudduth]

Wow... I'm simply blown away with this content---between this and Chris Greer, I am learning so much about how networking works---beyond what I've learned in my career in the support trenches.

I'm going to have to watch this one again--equipped with a notebook, and then go hit the site and buy the full course to expand that knownledge. Thanks for doing this, both yourself and Ed Harmoush!

[Frack_Black]

Great to see this collaboration with Ed, been following his channel for a while now. He has a very good, natural, delivery style and hits all the detail without cluttering it up with unnecessary info. Fair play David for throwing some exposure his way.👏👏

[paddymcgrath]

That was the best tutorial on SSL I've seen. Ed is a fantastic layman's terms teacher. I'll definitely be taking up the coupon and doing the course.

[kamalpreet]

Amazing, I dont think so anyone can explain TLS with this much detail and in such a simple and crisp way. Love your work David and Ed. I never comment of videos but this one has made me to to comment and follow both of you!!!

[aviborse]

This is a Gold mine!! I have been trying to find this explanation for quite sometime. Awesomely explained and i love the passion Ed. So the first thing i do support Ed by subscribing to his course and ensuring the knowledge stays with me in my repo. Thank you both of you!! Keep up the good work Ed and David. God Bless

[geoffreyvanwyk]

Congratulations David and Ed on your awards! And thank you for this enjoyable and informative lecture.

[mikehavekin]

Superb presentation. The depth and abliity to present these complex topics in such a manner takes real skill. Ed i'm signing up to your SSl course tonight, i am tight but you've put so much work in these videos i feel you deserve something back.

[Don-Carillo]

Two masters of the game right here. Ed's channel is absolutely superb. TLS, OSPF, NAT etc can be
quite complicated but he makes it so easy to absorb without leaving any stone unturned. Can't reccomend it enough. Been waiting for this collab. Cheers both 👍

[kukuwawakukuwawa]

Immediately subscribed to Ed after the first 10 mins of the video. He is so good at explaining the concepts. Thank you David for sharing this collab.

[setsura]

I had in-person course with Ed, he is absolutely a very very talented instructor, I still remember the day he taught us about subnets, networking stuff, he just made all the things very easy to understand. Glad to see Ed again here!

[Hardik-likd]

Thank you Devid and Ed Harmoush :) for this video 🙏
I think this is the only video on YouTube that explains the TLS handshake in such detail.

[justinhunt]

This was such a great video, I thoroughly enjoyed it and am the information that yall gave! Thank you both for your time putting this together!

[millacentbystander]

David again thank you so much for making the analogies and simplified explanation.
Thank you to your guest as well, absolutely brilliant presentation.
David you chime in at the perfect time.
