[ahmetsahin]

You explained GF for AES very well without going into mathematical detail. Thanks for the video :)

[iTechDude]

I LOVE YOU. I WAS SO CONFUSED ON HOW TO DO COLUMN MULTIPLICATION FOR AES BUT YOU EXPLAINED IT SO WELL. THANK

Clear Explanation, Swift moving between slides, great explanation from basic level, covering all sort of audience. Thanks a lot for uploading and sharing the content.

Amazing... I am tired from last 3 days... Because of Mixing Columns...
You explained very well and simply :)... Thank You very much Sir.

Thanks for the explanation, especially for Mix Columns :)

[timetriad]

Great job! This detail is so hard to find, and many other sources in both print and video always seem to gloss over the details of the math. Using binary notation instead of polynomial notation is so much easier! 👍🏻👍🏻👍🏻

[AUTM]

thank you!!! this video finally managed to explain mix columns for me

[mounirettaous]

thank you so much i didn't find someone explained as like.

[rozitaahammad]

Thank you very much sir for the clear explanation on the mix column :)

Dear Natarajan,
there seems to be a mistake at 23:30 following: the representative for c=12 should be 1100, doesn't it?
Anyway - it is the best video I found so far on this pretty confusing "field".
Thanks a lot!

IS there any reason why did the constant matrix is [[02 03 01], [01 02 03 01], [01, 01, 02, 03], [03, 01, 01, 02]]

[harshinikomalla]

Sir, I have a doubt.why do we use gf(2^8) only in aes and why not in des
