Bitwise Operators 3: The XOR Operation
This computer science video describes the bitwise operation XOR. It explains how the XOR (eXclusive OR) operation works with unsigned integers and how the XOR operation can be used with a bitmask to manipulate the contents of a register containing bit flags. It also demonstrates how the XOR operation can be used in symmetric key cryptography and is therefore fundamental to a number of modern cryptosystems. The equivalent XOR operators are demonstrated in VB.NET, JavaScript and Python.
