What if the plain text has an odd number of letters, how to group them in a pair of two. In the given example as 'e' was repeated in 'tree' so you introduced x which made the total number of characters/letters of the plain text = 26 that is even. Can you explain the case of total number of odd letters with no repetations?
can you please make English version of Playfair Cipher. I don't understand hindi. Your tutorials helped me a lot in past ...i can understand they way u teaching!!
Hn to apne bole ki hamare (HI) ke case me H aur I same column ya same column me nahi hey so encryption rule me dekhe to for H : H ka row aur I ka column jaha intersect hoga wahi hamara H ka CipherText hoga = B for I : I ka row aur H ka column jaha intersect karenge wahi I ka CipherText hoga = M but apne uske baad decryption ke case me bole ki iska ulta process hoga par ye reverse rule na sirf isi case me apply nahi hoga Same row and same column me koi 2 letter pair nahi hey to uska encryption and decryption ka process same he hoga aap try kar sakte hey. par apne ulta information dediya ki encryption me row and column intersection hoga aur decryption me column and row intersection hoga so app check recheck kijiye please.
what to do if i and j come together and if the number of alphabets in plain text is odd, I mean when there is only one alphabet coming at last when comparing it with the matrix?
Ma'am suppose with your example if a plaintext pair is 'fl', its in the same row in your example, what will be the cipher text for that, as f is in the corner

What if the plain text has an odd number of letters, how to group them in a pair of two. In the given example as 'e' was repeated in 'tree' so you introduced x which made the total number of characters/letters of the plain text = 26 that is even. Can you explain the case of total number of odd letters with no repetations?
Shashank, if the plain text has odd number of letters, you've to pair the last remaining letter with a dummy character 'x'
@@CSEconceptswithParinita was it 'x' or 'z' ?
And also just to confirm, if we have a word with two consecutive 'xx' we insert 'z' in between. Right ?
@@SHASHANKSHEKHARANS yes, that's right. And when we've odd number of characters, we normally append 'x' at the end.

in decryption, should we add x in between repeating characters?

In case if we have ij letters pair in plain text what will be the output in cipher text?
If pairs are repeated so we have to write them again or not

Hn to apne bole ki hamare (HI) ke case me H aur I same column ya same column me nahi hey so encryption rule me dekhe to
for H : H ka row aur I ka column jaha intersect hoga wahi hamara H ka CipherText hoga = B
for I : I ka row aur H ka column jaha intersect karenge wahi I ka CipherText hoga = M
but apne uske baad decryption ke case me bole ki iska ulta process hoga par ye reverse rule na sirf isi case me apply nahi hoga
Same row and same column me koi 2 letter pair nahi hey to uska encryption and decryption ka process same he hoga aap try kar sakte hey.
par apne ulta information dediya ki encryption me row and column intersection hoga aur decryption me column and row intersection hoga so app check recheck kijiye please.
