You are doing a great job and teaching far better than institutional teachers the graphics keeps us in touch with the lecture seems like a board interactive lecture thank u for this God Bless u keep up brother
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.
Very nice lecture👏👏... Only useful content no unuse talks. Appreciate's you😊😊
Many thanks for this. It clearly explains the concepts
just wow man!!! love your style ❤
U r awesome neso
Subscribed!!!
Very helpful and understandable thanks ❤️
Thank you for helping me understand because it helped me a lot in studying
Thank you again
This content is out of this world. A related book I read was life-affirming. "Game Theory and the Pursuit of Algorithmic Fairness" by Jack Frostwell
Amazing lecture ❤❤🎉🎉🎉🎉
Thanks you to much
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?
Thank you so much I want to learn c++ please suggest
I want to communicate with you that your explanation is the best
please please sir can you explain how conventational algorithm works
Nice
What if I/J appear in the keyword?
what if i and j are both used in the encryption key?
It's a matter of Human Intellect, then.
6:58
if keyword has repeating char. the ? can we include repeating char in the table or not?
I think I/J signifies the Pigeonhole Principle.
Good thinking. wonderful
no it's not
what if the last letter in plain text is x alone
if our plaintext is max , then what is the digram? is it ma xx
Hello Sir, How to split into digrams
if Plain text is balloon
If x is an extra character then what can we do
Xe ro x ???
Z
why haven'r you covered THE PIG PEN CYPHER i think it would be of value
What if last odd letter will be x
Can u provide ppts
Why I/j only in one shell why not other alphabets
Balloons ke liye filler btao

Namaku sriutami alias nandang ook no sepiking Inggris sepiking Indonesia 🙏
❤️
Why only i and j are combined, why not other??
Did you found it why?
