Lecture 4: Attention for Playfair Cipher

Dear Students,
For the case "WHEN BOTH LETTERS OF A PAIR ARE IN DIFFERENT ROW" each plaintext letter in a pair should be replaced by the letter that lies in its own row and the column occupied by the other plaintext letter.

Example: "ME" becomes "GD" (in the given example)

So the encryption of "MEET ME AT THE BRIDGEX" should be GD DO GD RQ PR SD HM EM BV. Note that, the pair AT should be encrypted as RQ not QR (has been written as QR on board during lecture). Similar things applicable for HM, EM, BV.

In the lecture around 26:24 min, we have shown a slide in which the rule and actual ciphertext is given.
