bless your heart, you have saved me. Thank you, I pray for many generations of your family good fortune.

Ur A Channel covers almost Every Important topics of Cryptography And Network systems 💯...helped Me a lot to pass ...Thank You very Much Sir 👌👏👏👏

you should explain why/how Alice and Bob are both aware of (a, q) -> these need to be publicly exchanged first before they can compute Ya and Yb

Very informative video. Thanks for sharing

I love the fact, that you suggest using HTTPS as a solution to savely generate a shared key, with Diffie-Hellmann.
Because in essence HTTPS uses RSA to generate a shared key, wich is then used to encrypt the Messages between Alice and Bob so that they can communicate, without a 3rd Party interfering the messages. And over this secure connection, you would then calculate an other key with Diffie-Hellmann wich is your second shared secret (after the RSA key for HTTPS).

So why simply dont use Diffie-Hellmann and use RSA for key Exchange?

was expecting for ways of Preventing MITMA in Diffie-Hellman to have been more on how to advance the protocol eg by use of authentication certificates or something.

Difference with RSA algorithm pls explain

[ayushantre]

how do they calculate k without private key

[ShopperPlug]

WTF... this means diffe hellman key exchange is completely useless. I thought diffe hellman key exchange sole purpose was to prevent a man in the meddle attack even when there is one occurring. The secret key is what makes the data un readable by the attacker. from my understanding the attacker takes both parties' public key and provides them the with an attacker public key... that is just slick and scary...

[DeRizzlo]

Ok but how does the attacker knows the initial agreed upon values of a and q to generate his own public key
