<?
$Key="Key-Longer_Than_Password";
$Password="Secret";
$Encrypted=$Password ^ $Key;
$Original_Password=$Encrypted ^$Key;
print "The original Password is: $Original_Password<BR>";
?>
The original Password is: Secret

NOTE, The value of $Encrypted may not be a printable string(especially in a
broswer). It should work fine for your purposes.

Code example, please? What I tried didn't do anything so I'm
not sure if I'm doing it right...
