The four-square cipher uses four 5 by 5 (5x5) matrices arranged in a square. Each of the 5 by 5 matrices contains the letters of the alphabet (usually omitting "Q" or putting both "I" and "J" in the same location to reduce the alphabet to fit). In general, the upper-left and lower-right matrices are the "plaintext squares" … See more The four-square cipher is a manual symmetric encryption technique. It was invented by the French cryptographer Felix Delastelle.

WebPlayfair cipher is an encryption algorithm to encrypt or encode a message. It is the same as a traditional cipher. The only difference is that it encrypts a digraph (a pair of two letters) instead of a single letter. It initially creates a key-table of 5*5 matrix. The matrix contains alphabets that act as the key for encryption of the plaintext.
