However The Playfair cipher or Playfair square or Wheatstone���Playfair cipher is a manual symmetric encryption technique and was the first literal digram substitution cipher. The Playfair cipher or Playfair square is a manual symmetric encryption technique and was the first literal digraph substitution cipher. It was invented by Charles Wheatstone in 1854 who bears the name of Lord Playfair. Playfair cipher is the best-known multiple letter encryption cipher. The cipher replaces each pair of letters in the plaintext with another pair of letters, so it is a type of digraph cipher.As an example, let's encrypt the message 'Meet me at the Hammersmith Bridge tonight'.
