Webcipher: [noun] zero 1a. one that has no weight, worth, or influence : nonentity. WebTo understand why, we need to first introduce the AND, OR and XOR bitwise operations. Specifically why XOR must be used when performing the one-time pad on computers. Bitwise simply means that we are dealing with individual bits, or binary numbers. In any modern/computerized encryption scheme we represent our symbols using binary digits.
