Webare needed in order that p and c can be assigned a letter of the alphabet. We can illustrate these equations as follows: If the ciphertext letter is F, then we have c =6, since F is the 6th letter of the alphabet. Using equation (4), we nd p c − 2 mod 26, or p 4 mod 26. So the plaintext must be D, the fourth letter of the alphabet. On the other

In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be replaced by A, E woul…
