Thank you, finally a step by step explanation of the entire request process. I was having a hard time understanding how the certificate was verified. I watched 3 videos of yours: 1) digital signatures, 2) digital certificates 3) (this one) How SSL certificate Works.... that gave me a much better understanding of this material.

[dcojelo]

Really, THE BEST AND CONCISE explanation about https and ssl ever, thank you!!

[kirafortherescue]

That's what I was searching for!! How the algorithms work themselves because I'm a programmer and I'm trying to learn about HTTPS & Thank you, you really helped me a lot rather than other videos on youtube & articles everywhere on google which only tells you that SSL is secure... really they're not any useful but your video is the one that does.
