None.

<h1>Description</h1>
<table>
<tr>
<td>
Often used for lightweight (meaning worthless ;) encryption, this will take  two values and perform an exclusive OR with each bit following the basic rules  of XOR. The result can be XORed with one of the original numbers to reveal the  other number. See the example for more.
