WebIn the generalized version of Caesar’s cipher each alphabet is replaced with another alphabet after shifting it x times to the right. The amount of the shift (x) is the encryption key. For the decryption process, we reverse the process and replace the ciphertext alphabet with the alphabet after doing a left shift by x alphabets. WebConsider a multiplicative cipher defined by C = (P x k) mod 26 analogous to the generalized (additive) Caesar cipher. What is the encryption of “goodby” using the key k = 7? What is the formula for decryption? How many different keys are possible? Explain. Expert Answer " The encryption of "goodby" using the key k = 7 is "ollehb".

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 … See more The transformation can be represented by aligning two alphabets; the cipher alphabet is the plain alphabet rotated left or right by some number of positions. For instance, here is a Caesar cipher using a left rotation of three … See more The Caesar cipher is named after Julius Caesar, who, according to Suetonius, used it with a shift of three (A becoming D when encrypting, and D becoming A when decrypting) to protect messages of military significance.
