WebJun 21, 2024 · A key used by an encryption algorithm is a bit string. A 128-bit key will have exactly 128 bits in it, i.e. 16 bytes. You will often see keys written in hexadecimal format where each character represents 4 bits, e.g. "FEDCBA98765432100123456789ABCDEF" represents 16 bytes or 128 bits. The actual bits in this example are WebThe concept is similar for the OR operation. Its truth table shows a result of a 1 in all cases except when both inputs are zero.
