[@prachi1888]

Very nice lecture👏👏... Only useful content no unuse talks. Appreciate's you😊😊

[@jimratter5561]

Thank you for this clear and detailed explanation of playfair cipher. I read about it in a book, "covert radio agents 1939-1945", but could not fully understand it.

Super sir ❤❤❤ 10/10 explanation n presentation

[@pythonsuzan9554]

just wow man!!! love your style ❤

[@friendsinn1987]

Many thanks for this. It clearly explains the concepts

Thank you for helping me understand because it helped me a lot in studying Thank you again

what if i and j are both used in the encryption key?

[@TheMR-777]

It's a matter of Human Intellect, then.

@@simrakhan6346 I meant, it's up to our analytical skill then. Once we plug either of them in the decrypted string, by analyzing the whole string, it gets clear whether our choice was right. Since, both i and j are two very different (sounding) letters, and they can't be confused together. (anyways, thanks for the nostalgia. I was graduating in COVID, back when I watched that video).

if I were a part of the keyword. then can we couple any unused letters together or it has to be j and some other letter?

I want to communicate with you that your explanation is the best

U r awesome neso

What if I/J appear in the keyword?

[@MohdAsim-vh4ek]

I think I/J signifies the Pigeonhole Principle.

[@actionplay1018]

Good thinking. wonderful

[@bhubanmondal05]

no it's not

[@SohamD-gz8so]

What if ij is a pair in the plain text, then how would we consider ?

please please sir can you explain how conventational algorithm works

if keyword has repeating char. the ? can we include repeating char in the table or not?

Hello Sir, How to split into digrams if Plain text is balloon

[@shantoshpersonal9282]

if our plaintext is max , then what is the digram? is it ma xx

[@ARSAGAMING69]

Is digraph and digram are same ?? . . Anyone ??

[@mos-ees]

If x is an extra character then what can we do Xe ro x ???

[@Tradinggangg]

Z

Why only i and j are combined, why not other??

can anybody tell how to decide filler letter ?

what if the last letter in plain text is x alone

why haven'r you covered THE PIG PEN CYPHER i think it would be of value

[@jagadeswarreddyreddam5637]

What if last odd letter will be x

[@jyotsnavangepuram1890]

Why I/j only in one shell why not other alphabets

[@Education22.25]

The algorithm takes 5*5 square key and J has very low occurance so he combined it with I for fiiting in 5*5 key square
