WebMar 21, 2024 · The Bitwise Algorithms is used to perform operations at the bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are sometimes used to improve the efficiency of a program. For example: To check if a number is even or odd. This can be easily done by using Bitwise-AND (&) operator. WebBitshifts and especially rotations are so widely used because they promote good diffusion. Many (most?) modern-day cryptographic constructs are built on the concept of rounds, where you take the plaintext and execute many rounds of some operations on it.
