Repetitive, exhaustive... perfect! There's no ambiguity in this lesson! Thank you!

[@SatishCJ]

Glad it was helpful!

[@buse740]

I was struggling with my own AES lecture notes but you can not image how helpful was this video thank you sir

[@SatishCJ]

You are most welcome

[@baharl2981]

this is the only explained key expansion very well.... can't thank you enough !

[@SatishCJ]

Thanks for the nice feedback

[@stefanabreu]

You are an amazing teacher. Thank you for your hard work!

[@SatishCJ]

You're very welcome!. Thanks for the wonderful feedback

[@akshayyeluru5443]

Best and clean video I have ever scene, Your Explanation is amazing

[@BiddyutHasan]

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..

[@thebigvusi3377]

There was no better way to explain this, you explained it very well thank you sir 🙏🏻

[@ericzuckerburg6292]

Thank you very much; your explanations are very clear. thank you for showing the little details.

Thank you sooooo much Sir I had many doubts but your video cleard all of them ❤

[@SatishCJ]

Glad to hear that. Thanks for the feedback

Another excellent video!

[@naodtesfalem6758]

Perfect, just perfect!!

Thanks for the nice feedback

[@cookingfordummies24]

Very Clear..Thank You

[@ridakhalid6176]

Amazing explanation 👍

[@ishaqahmad]

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

[@ssambadenis9401]

Your lectures help me alot. Thanks

[@shanky3572]

Hi, Big fan of your video, I have a small doubt,what are round constant and how are they calculated?

[@studyaccount7682]

Amazing explanation ..❤️

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

[@ayeshamanzoor9150]

Perfect 👌🏻

[@tahseenamahmud8751]

I am blown away

[@maliqattan]

best explain. Thank you sir very much

[@RAJMOHAN-od7fi]

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?

[@rG-ou3jf]

Well done sir

[@iazeemabbas]

Amazing explanation

[@ed1849x]

AWESOME!

[@powell3376]

thanks, this really helped.

[@erickchauke4201]

Wits students end up here, thank you

[@RohitVerma-cz3gu]

thanks a lot sir well explained

[@shahbazyounasyounas5731]

I agree with Akshay

[@deepasavant821]

How words are converted to binary form

[@md.shadab7208]

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.

[@explosion573]

Very well explained

[@krishnakishore7577]

Sir, It's very clear, Can I get PPT For AES ALGORITHM including round steps Thank you

[@muhammadkashan7219]

Sir I mistake I'm plain text conversion at first during xor 12 byte answer is wrong

[@AbhijitGiri123]

Very well explained sir

[@knowledgepeace4848]

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.

[@kevinkehoe9950]

I'm pretty sure it will be a 4 x 6 rather than 4x4

[@thb8786]

@@kevinkehoe9950 i also think same... for 256-bit key there will be 4 x 8 matrices. If you have any reference please share.. Thanks

[@BiddyutHasan]

Please explain the S-box in AES and its internal logic for which it is established?

[@adityaj7664]

Also, how is your research going on in AES? I'm a researcher/ student i'd be interested to collaborate

Hello sir i need your help, what is the diffirence in the key expansion algorithms of aes128 and aes256?

[@gm700]

Sir, What if the input data size is less than 128 bits?

[@gm700]

Plz rply sir

Kindly sir tell us about 192bit and 256bit key covert into 128 bit in AES

[@joygorai9841]

How the round constants are calculated?

[@SatishCJ]

I am sorry.. Didn't explore that..
