WebWe can illustrate these equations as follows: If the ciphertext letter is F, then we havec=6, since F is the 6th letter of the alphabet. Using equation (4), we ndp c −2 mod 26, or p 4 mod 26. So the plaintext must be D, the fourth letter of the alphabet. On the other hand, if the ciphertext was A, we would ndp c−2 mod 26, orp 1−2=−1 mod 26. WebWhat is cryptography?
