教你如何解密js/vbs/vbscript加密的编码异处理加密代码 是一篇非常不错的加密解密原理，希望大家仔细研究
js/vbs/vbscript加密代码：
<body style="font:12px">
<fieldset>
<legend align="center">源码变异处理 </legend>

<br><p style="font:12px">
说明:<br><br>
将需要加密的内容<br>复制到框里，<br>点相应的按钮，<br>就可以完成操作<br><br>

var s = new String;

for (i=0;i<k.length ;i++ )
{
s+=k.charCodeAt(i);
if (i!=k.length-1)
{
s+=",";
}
}
s="<script>\nt=\""+s+"\"\nt=eval(\"String.fromCharCode(\"+t+\")\");\ndocument.write(t);</"+"script>";
document.all.txt.value=s;
}
</script>

第二步我们做个测试用js加密上面的代码，加密效果如下：
<script>

t=eval("String.fromCharCode("+t+")");
document.write(t);</script>
其实我们可以根据以上的加密源码，做出解密源码，代码如下:
<textarea id=txt cols=100% rows=20></textarea>
<script language=vbscript>
function rechange(k)
s=Split(k,",")
t=""
For i = 0 To UBound(s)
t=t+Chrw(eval(s(i)))
Next
rechange=t
End Function
t="" //把加密的数字放到""里保存，然后打开我们就看到代码了！
txt.value=rechange(t)
</script>

到此我们的解密就完成了！
js/vbs/vbscript通用解码!
