typer:function(key){
$m=[70,70,71,79,86,74,71,83,80,74,77,86,81,95];//times alt is pressed for Access Granted
$c=Typer.counter-211;
if (!Typer.failed & $c>=0){
if (!(key==$m[$c]-$c)){
Typer.failed=true;
Typer.makeDenied();
}
if($c+1==$m.length){
Typer.makeAccess()
}
}// remove all existing popuccess();
},

key = ""
m = [70,70,71,79,86,74,71,83,80,74,77,86,81,95]
for i in range(len(m)):
key += chr(m[i]-i)
print(key)

得到:
