Since only the order of characters in the alphabets has been changed, the security of this cipher is identical to that of the Vigenère cipher. Not seeing the correct result? Its most famous application was in a rotor-based cipher machine, the Hagelin M-209. We have a Vigenère table, and are trying to guess the keyword. PlayFair Cipher is a symmetrical encryption process based on a polygrammic substitution. Beaufort is a French town in Savoie, known for its cheese, any reference to these elements can be a clue. In general, a cipher is simply just a set of steps (an algorithm) for performing both an encryption, and the corresponding decryption. Where Vigenere adds the message to the key, Beaufort subtract the message to the key. We use multiple one-character keys, each key encrypts one plain-text character. El cifrado Beaufort, creado por Sir Francis Beaufort, es un cifrado de sustitución similar al cifrado Vigenère, con un mecanismo de cifrado y un cuadro ligeramente modificado .
