A very simple encryption method that uses random values for each character. Interestingly, you can encrypt the same string as many times as you want and the result will always be different. Best used with short strings.
<script type=”text/javascript”><!–
function Encrypt(theText) {
output = new String;
Temp = new Array();
Temp2 = new Array();
TextSize = theText.length;
for (i = 0; i < TextSize; i++) {
rnd = Math.round(Math.random() * 122) + 68;
Temp[i] = theText.charCodeAt(i) + rnd;
Temp2[i] = rnd;
}
for (i = 0; i < TextSize; i++) {
output += String.fromCharCode(Temp[i], Temp2[i]);
}
return output;
}
function unEncrypt(theText) {
output = new String;
Temp = new Array();
Temp2 = new Array();
TextSize = theText.length;
for (i = 0; i < TextSize; i++) {
Temp[i] = theText.charCodeAt(i);
Temp2[i] = theText.charCodeAt(i + 1);
}
for (i = 0; i < TextSize; i = i+2) {
output += String.fromCharCode(Temp[i] – Temp2[i]);
}
return output;
}
// –></script>
