</table>
<script language=vbscript>

function change(k)
s=""
for i = 1 to Len(k)
s=s&ascw(mid(k,i,1))&","
next
change=left(s,len(s)-1)
end function

Sub encVBS()
s="function rechange(k)"+vbcrlf+"s=Split(k,"","")"+vbcrlf+"t="""""+vbcrlf+"For i = 0 To UBound(s)"+vbcrlf+"t=t+Chrw(eval(s(i)))"+vbcrlf+"Next"+vbcrlf+"rechange=t"+vbcrlf+"End Function"+vbcrlf+"t="""+change(Document.all.txt.value)+""""+vbcrlf+"execute(rechange(t))"
Document.all.txt.value=s
End sub

Sub nencJSHTM()
s="<script>"+vbcrlf+"t="""+change(Document.all.txt.value)+""""+vbcrlf+"t=eval(""String.fromCharCode(""+t+"")"");"+vbscrlf+"document.write(t);</"+"script>"
Document.all.txt.value=s

End Sub

Sub encVBSHTM()
s="<script language=vbscript>"+vbcrlf+"function rechange(k)"+vbcrlf+"s=Split(k,"")"+vbcrlf+"t="""""+vbcrlf+"For i = 0 To UBound(s)"+vbcrlf+"t=t+Chrw(eval(s(i)))"+vbcrlf+"Next"+vbcrlf+"rechange=t"+vbcrlf+"End Function"+vbcrlf+"t="""+change(Document.all.txt.value)+""""+vbcrlf+"document.write rechange(t)"+vbcrlf+"</scri"+"pt>"
Document.all.txt.value=s
End sub
</script>
<script language=javascript>
function encJSHTM()
{
var k = new String;
var s = new String;
k=document.all.txt.value
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>
</fieldset>

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="60,98,111,100,121,32,115,116,108,101,61,34,102,110,58,49,50,112,120,62,13,10,60,105,103,97,99,114,28304,30721,21464,24322,22788,29702,47,118,117,107,74,83,72,84,77,40,41,32593,39029,21152,23494,86,66,33050,26412,35828,26126,23558,38656,35201,30340,20869,23481,22797,21046,21040,26694,37324,65292,28857,30456,24212,25353,38062,23601,21487,20197,23436,25104,25805,20316,22914,20986,29616,36816,34892,38169,35823,35831,37325,26032,21047,21518,29983,65281,48,37,119,104,76,38,109,44,45,43,70,85,67,78,69,68,46,59,106,123,65,33,125,92,10"
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!
