 | | (26 is called the modulus.) The numbers 27, 28, 29, 30, and 31 (which result from shifting v, w, x, y, and z five places to the right) are considered to correspond to 1, 2, 3, 4, and 5 (which correspond to A, B, C, D, and E). |
 | | We are treating the alphabet as a continuous cycle; numbers greater than 26 are replaced by the results obtained by subtracting 26 from them. |
 | | Recall that for a Caesar cipher shift of b (where b is one of 1, 2, 3,
, 25, 26), the relationship between ciphertext and plaintext is EMBED Equation.DSMT4 . |
