I'm too privileged and learnt from your style of teaching. Actually I want to focus the AES in my upcoming research. I would be obliged if you suggest and support me by putting your exact point mention in AES to me at the earliest..
Its an amazing and excellent explanation. I have one question that is for round 1 you have selected round constant 1 in the constant table, for round 2 you have written round constant 2 then why not for round 3 the round constant should be 3 and for round 4 should have round constant 4 while there is 4 for round 3 and for round 4 is a round constant 8
Last state matrix has errors....if we do xor between message and expanded key we get below output 0, 16, 1a, 17 4, 1c, 0, 7 17, e, 3, 1 1b, f, 8, 10 In the last line instead of 8 your video shows 0f...i think that is wrong....can you check and correct it?
Each word consists of 4 bytes. Each byte of a word is represented in a hexadecimal form. The rule of conversion of hexadecimal to binary is, take each character of a hexadecimal number and convert that into a 4 bit binary number. I hope you know how to convert hexadecimal to binary.
A great explanation, thank you. I wonder if you could explain the key size 192-bit. The 128-bit key fits into a 4 by 4 block but what about a 192-bit key? Do we still use a 4 by 4 block? And if so, what happens to the remaining bits? I know I am of missing something but don't know what.
Repetitive, exhaustive... perfect! There's no ambiguity in this lesson! Thank you!
Glad it was helpful!
I was struggling with my own AES lecture notes but you can not image how helpful was this video thank you sir
You are most welcome
You are an amazing teacher. Thank you for your hard work!
You're very welcome!. Thanks for the wonderful feedback
this is the only explained key expansion very well.... can't thank you enough !
Thanks for the nice feedback

Best and clean video I have ever scene, Your Explanation is amazing
Thank you very much; your explanations are very clear. thank you for showing the little details.
There was no better way to explain this, you explained it very well thank you sir 🙏🏻
Another excellent video!
Thank you sooooo much Sir I had many doubts but your video cleard all of them ❤
Glad to hear that. Thanks for the feedback
I can't thank you enough sir, May God bless you🥰
You are most welcome
Amazing explanation 👍
Your lectures help me alot. Thanks
Perfect, just perfect!!
Thanks for the nice feedback
Very Clear..Thank You
great video sir like it alot much love
Thanks for the visit
@@SatishCJ im working on AES128 in python and your videos help me alot, keep doing the good work sir
best explain. Thank you sir very much
Amazing explanation ..❤️
U are best sir🙏
I am blown away
Well done sir
Hi,
Big fan of your video,
I have a small doubt,what are round constant and how are they calculated?
Its an amazing and excellent explanation. I have one question that is for round 1 you have selected round constant 1 in the constant table, for round 2 you have written round constant 2 then why not for round 3 the round constant should be 3 and for round 4 should have round constant 4 while there is 4 for round 3 and for round 4 is a round constant 8
Amazing explanation
hi i have small doubt key 128 bit we converted 4*4 matrix with w0, w1, w2, and w3, but in key 256 what is the matrix size how to do key expansion
Wits students end up here, thank you
Perfect 👌🏻
AWESOME!
Very well explained
Sathishcjisneverboring sir 😎
thanks a lot sir well explained
Very well explained sir
Last state matrix has errors....if we do xor between message and expanded key we get below output
0, 16, 1a, 17
4, 1c, 0, 7
17, e, 3, 1
1b, f, 8, 10
In the last line instead of 8 your video shows 0f...i think that is wrong....can you check and correct it?
Hello sir i need your help, what is the diffirence in the key expansion algorithms of aes128 and aes256?
thanks, this really helped.
Sir, It's very clear, Can I get PPT For AES ALGORITHM including round steps
Thank you
How words are converted to binary form
Each word consists of 4 bytes. Each byte of a word is represented in a hexadecimal form. The rule of conversion of hexadecimal to binary is, take each character of a hexadecimal number and convert that into a 4 bit binary number. I hope you know how to convert hexadecimal to binary.
I agree with Akshay
Please explain the S-box in AES and its internal logic for which it is established?
Also, how is your research going on in AES? I'm a researcher/ student i'd be interested to collaborate
@@adityaj7664 Please send source code of AES in C
How to encrypt images sir ,do one vedio in detail sir
Kindly sir tell us about 192bit and 256bit key covert into 128 bit in AES
Sir I mistake I'm plain text conversion at first during xor 12 byte answer is wrong
Thank you so much

I'm pretty sure it will be a 4 x 6 rather than 4x4
@@kevinkehoe9950 i also think same... for 256-bit key there will be 4 x 8 matrices. If you have any reference please share.. Thanks
Sir, What if the input data size is less than 128 bits?
Plz rply sir
How the round constants are calculated?
I am sorry.. Didn't explore that..
