How End-to-End encryption Works?

Great video Hussein. If I may explain this for your audience with some math - ·       Bob generates a private key number X ·       Alice generates a private key number Y ·       There are publicly known numbers A and N provided by the server. ·       Bob does A raised to X and sends the number to Alice ·       Alice does A raised to Y and sends the number to Bob ·       They both raise what the other sent with their own secret key i.e. Bob now has A raised to YX and Alice now has A raised to XY which is the same number. They also mod it with N to get a manageable number between 0 and N. They now have the same secret key without knowing each other's private keys and without the server knowing the final key. The server only knows A and N. The trick is to make X, Y and N sufficiently large to make reverse engineering near impossible.

man you're the most backend youtuber in the entirety of YouTube, love your content 👍❤❤👍

Even without graphics and illustrations - this was an excellent and clear explanation !

You're the best! From daily doubts I have to more deep studying I do I can find some video here on your channel explaining topics with honesty and a great background. Thanks from Rio de Janeiro, Hussein!

You look good in groomed beard and I agree that you are the rarest of backend youtuber.

The explanation couldn't have been any better... Great job🤝

Great contente. The best backend channel 🖤

Such a great explanation. Thanks, Hussein!

And I really thought WhatsApp works with Asymmetric all the time. Each user has their own private/public key pair. But you made it clear now that it works similarly to TLS 1.3 Diffie Hellman. 👌

Buddy your videos are really addictive.

You are awesome Hussein! please upload more. Thank you for this video.

Excellent explanation, no need for fancy visuals if it makes sense!

Great explanation

fantastic, so basically double encryption

Great explanation. Thank you for your efflorts

Great video. Thank you! Btw for persistence do we store that encrypted thingy in the DB directly?

Many thanks

Very nice

That last CA you talked about was DigiNotar....darket diaries made a video about that.

cool video)
