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?

WebIn cryptography, we use A=0 ... Z=25. This makes sense, because if a shift is 0 you can assume that the letters were shifted by 0, which means they were shifted by nothing. Any letter shifted by 0 is that letter. Think of it like addition: you are adding a number. Any number + 0 is that number, therefore A+0 is A, right?
