Time to delve into the chain of trust and the contents of SSL certificates.

Take a look at the actual chain of trusted certificates used by HSBC and understand step by step what all the key fields mean and how the chain of trust is established.

This is by far the best series on Cryptography & SSL I have ever seen. Seriously. I'm baffled that these videos don't have more views.

I’ve watched numerous videos on this subject that aren’t anywhere near as clear and comprehensive as this one. Very much appreciated. Thank you!

[rogeriobarretto]

For the very first time I can say that I fully understood the whole concept in the details and that my friend is priceless. Thank you very much! This is gold.

The reason your videos are the best is because you repeat all the important points and hammer them home, so don't apologise for being repetitive it's why they're so damn good. Thank you so much for making something I couldn't figure out on my own easily understood in 5 videos.

The only video (literally) on youtube which explains properly every aspect of SSL .. Thanks so much !!

[ChristopherBushman]

This is the first video I have found (the whole video series actually) that takes the time to thoroughly the concepts of Cryptography in relation to SSL in an accessible manner. Thank you very much for taking the time to put these videos together. I have learned a great deal from this content.

I never commented on YouTube, but this video is by far the best I encountered so far and deserves a comment. I finally understand certificates and much more. Also, I began watching videos of Humpty Dumpty.

i heard Class 3 "EVB" more than once.
i binge watched the entire series and it was a worthy refreher.

Amazing video, thank you do much for sharing. Other folks pretend to know and regurgitate incorrect steps of the validation process, including some poorly written text books.

[billbauer]

This is a great video! I only wish I had seen it years ago! Thank you so much for the comprehensive explanations of the entire process.

[saravanaga]

Hello Matt Thomas, I was trying to understand the concepts explained in these video for long time, nowhere I could find clear explanation like this. Thank you so much.

Hi Matt - Great video. Did you get a chance to upload some videos on why Intermediate CA's are needed as opposed to sending CSR to TCA? You alluded this in the video and commented that future videos will cover this aspect. Looking forward to more in this series

[ashiqrehan]

hey Matt, i am from an infosec background with some basic knowledge on SSL/TLS and it was damn simple, clean, awesome presentation and explanation.
