WebJan 27, 2024 · The ciphertext generated by the One-Time pad is random, so it does not have any statistical relation with the plain text. The assignment is as follows: The relation between the key and plain text: In this algorithm, the length of the key should be equal to that of plain text. Examples: WebCaesar cipher is best known with a shift of 3, all other shifts are possible. Some shifts are known with other cipher names. Another variant changes the alphabet and introduces digits for example. A Caesar cipher with an offset of N corresponds to an Affine cipher Ax+B with A=1 and B=N.
