Why SSL, TLS, DTLS ??? | Data Security over Network | Integrity & Confidentiality | HTTPS internals

In this video I have given a brief introduction to concept of SSL, TLS and DTLS with necessary internal details. A separate topic on encryption techniques and certificates will be published soon.

[@sauravchandra9227]

probably the only video that explains DTLS in such depth and so easily. awesome work

[@serhiirumiantsev7736]

Wow what an extraordinary video. Never thought this type videos can also be published by youtube. Now I can proudly say I understood SSL.

The cookie is mainly used because it allows the server to be stateless during the hello world exchange, which means that in case of DOS attack it does not allocate a channel for the client until the next exchange.

Good 👍

[@taniakarmakar]

this really helped in clearing my doubts. I do see some discrepancy in the explanation at the certificate exchange stage. probably u can explain a bit more about the ServerHello stage. but nevertheless. its a good video to understand the basics. I really hope you upload detailed video related to certificates very soon. :)

[@cannyinformationcenter8236]

Sure I will make a separate video for Certificates soon as per request. Thanks for your valuable comments

[@showkatmeer5474]

Thanks, sir for explaining the security certificates, it might be better if u can explain it with the help of diagrams in future videos

[@dipan246]

Nice explanation. Could you please explain more in depth about client certificate authentication. If we have enabled the client side authentication, server will ask for client certificate. Then client will provide its certificate (which contains client's public key) to the server. After that in "Certificate Verify" client will encrypt previous handshake messages with its private key and send to the server. But here is the question, since everybody knows the client's public key and anybody can decrypt it, so how the confidentiality is maintain here. Please explain the 'Certificate Verify".
