Sir you have really helped me a lot.
Today was my exam. You have helped me for my semester exam.

I thank from my heart.

[maheshb]

Sir you have helped me a lot sir during my exams time. Your explonation is very goood and clear. Keep maintian that sir. You are one of the best teacher in my study career. I was scared about this subject and i found you on youtube. Now i learned lot of subject. Thank you very much sir.

Sir thank you your tutorial is one of the best videos i come across in cryptography please continue with the great work

[robertopizziol]

Really nicely explained! The only thing it's missing is the AES Key Expansion Algorithm. Thank you for your work :)

[utkanthsharma]

Thank you so much sir, it is indeed a boon to have you guide us with this cryptography stuff.

Important note: In the shift rows, circular left shift is done not circular right shift. Sir himself has verified this in comments but he didn't mark any annotation in the video. I am just writing it here so that who ever reads this correct him/herself. You can also check sir comments in replies below where he apologizes for his mistake. By the way your tutorials are nice sir.

[ayush_sri]

You did a great job. Very Well Explained. Thanks!

[dr.s.geethagascwcbecsdept]

Really wonderful explanation to complex AES algo.

[beizhou]

Hi, thanks for the videos. In this tutorial, within the shift row operation, Row 1 should left shift 1 byte, not 1 bits according to the diagram you demonstrated.

Hello sir, we all are following ur lecture in this lockdown.

[the.aravind.sankar]

Thank You Sir! Your videos helped a lot. Keep up the good work. I shared your videos among my friends.

One correction, In the shift Rows transformation of the round, the shift is by 1 byte and NOT one bit.

[md.arifulislam]

Excellent explanation, Love the way of your teaching, lots of thanks and love

[srivallimadduri]

Thank you for posting such a great content which helps us to learn n understand quickly
