A: How can the Caesar cipher be implemented in Java? The formulas for encryption and decryption require a positive value of the modulo operation. However, this is not guaranteed for all implementations of the modulo operator. For instance, in Python the modulo value is always positive (e.g. `-2 % 5 = 3`), while in Java it can be negative (e.g. `-2 % 5 ... (more) |

How can the Caesar cipher be implemented in Java? The Caesar cipher is a substitution cipher in which the letters of an ordered alphabet are cyclically shifted by a given number. A detailed description can be found e.g. here. Let `u` be the index of the letter to be encrypted in the alphabet, `shift` the shift and `size` the number of letters of... (more) |
