I am in rabbit hole, he said in every video "that's what we talk about last time" so I am looking for last video and again and again and again... HELP :D

I like the way this guy talks and explains things, duno what it is. He obviously really knows his stuff to be able to explain it so well and simplify it enough for me to understand!😊 Thanks

This video is pure gold. I work in the IT industry and it's hard to find a better explanation than this about TLS.

I would be interested in a separate video about TLS 1.3 versus 1.2, especially related to Encrypted SNI (ESNI) and how if affects transparent proxies and other security tools

I like how he screams at the start.

Nothing better than a Friday Pounding.

11:28 this is an underrated piece of editing right here.

It's very convenient that you created these videos just when I decided to start learning TLS. Very clear and easy to understand. Only bad thing is that the adverts come at rather annoying times.

Thank you for explaining with context and really breaking it down. It’s the context and bit of history on how something came to being is what makes things interesting. Thousand kudos.

Cryptography is such a cool subject. Absolutely love it when Mike is on!

I forgive the camera man for hollering in to the mic so that it distorted like that cause he got Mike Pound on

what a energetic man, wish had a teacher like him. I could learn from him till I die

I think this video can serve as a sort of hub or strarting point for many Dr. Pound's videos, both existing and upcoming. Basically it lists in one string a lot of topics he covered, which is quite convenient.

New record for advert: 2:15. Two of them, of course, after two at the start. 2030: videos are now entirely adverts, no content. 2040: content is back, but only videos containing nothing but adverts are accepted

This guy explaining is awesome and inspired me to do my thesis on ROCA attack. you rock

The best explanation, that someone could find on the Internet. Thank you Michael

Wow ! I wish he was my teacher in college! I am glad that I found this channel. Thank you 🙏🏻

Hey Guys! It would be great to see you guys doing the promised difference between TLS1.2 and 1.3. I really like your videos! They are great to understand the basics of computer science and I like to watch videos related to the toppics i have in my master course. Greetings from Germany!
