You did a great job! Concise and to the point explanation. Please do upload more videos. It'll be really helpful if you solve William Stallings guideline problems in your examples. Please upload more videos soon.

I really love the way you explain everything in simple words which makes it quite effective. I am watching every video in this playlist and now I am enjoying the subject. All credit to you. Your explanations are reaching to the heart due to neat & clean notes and the Hindi language. I'm also preparing notes from the video. You have simply decrypted the complexities of the subject. I'll definitely watch the other playlist too now. Hats off to you. And THANK YOU.

[@My_channel6284]

hi. i want to ask you can we use any alphabet to replace together letters like you use x and z we use any letters

[@mayankkedia5342]

DOUBT: if we have to encrypt AH. Since they are in same row we will replace them with immediate right. A's immediate right is B but H's immediate right is I/J. So what should H be replaced with only I or only J or both I/J ??

[@akhilkhurana3489]

usually we omit 'j' from the grid

[@pawanvishwakarma1389]

Any would do..ur answer will be correct in both cases..but recommend letter is "i"

[@chetandivekar1813]

Mostly i because j is just omited and it's not consider

[@WannaBe-21]

Thanks for asking this doubt and helping students like me who open up the CZcams one night before the exam.

[@abdulsattar-jz5db]

what if we have to encrypt something like jimmy? and when we decrypt at the receiver end how could the receiver understand that z is the extra letter not in the original plaintext

Why we add x n z as bogus characters??

[@ajkhanzada3450]

sir what is the name of the book?????

[@nisarggaming9700]

Sir remidal ma ketla marks ma avi shake

[@gautambagla2461]

If we have HEXXOZ, then what will we add with the lonely z at the end? Should that be x?

[@thegreekgoat98]

I guess, can add x with z during pairing. So, the plain paired text would become Hexzxozx. So, the entire cipher text would be Bfyvynvy

[@ShouvikMitraPlus]

Plain text =."Hez",
hua toh kya hoga while converting the text into pair of alphabets(Step 3)?

[@sahil_satav4185]

maybe HE ZX not sure,coz when XX occurs we write XZ and other X with the next letter..

sir nice video
But what to do when the key is SAGAR.
I mean A is coming 2 times so how will we manage one surplus alphabet

I think key should be SAGR or invalid key
