In this operation, sometimes called ''rotate no carry'', the bits are "rotated" as if the left and right ends of the register were joined. The value that is shifted into the right during a left-shift is whatever value was shifted out on the left, and vice versa for a right-shift operation. This is useful if it is necessary to retain all the existing bits, and is frequently used in digital [[cryptography]].{{Clarification needed|reason=In what process in cryptography is it used?|date=August 2020}}
