EXclusive OR (eXclusive-OR) encryption requires that both encryptor and decryptor have access to the encryption key, but the encryption algorithm, while extremely simple, is nearly unbreakable. Exclusive-OR encrytion works by using the boolean algebra function exclusive-OR (XOR). XOR is a binary operator (meaning that it takes two arguments - similar to the additional sign, for example). By its name, exclusive OR, it is easy to infer (correctly, no less) that it will return true if one, and only one, of the two operators is true.
