Here is a short example of a Web page that includes some JScript code that needs protecting:

function verifyCorrectBrowser(){
if(navigator.appName == "Microsoft Internet Explorer")
if (navigator.appVersion.indexOf ("5.") >= 0)
return(true);
else
return(false);
}
function getAppropriatePage(){
var str1 = "Had this been an actual Web site, a page compatible with ";
var str2 = "browsers other than ";
var str3 = "Microsoft Internet Explorer 5.0 ";
var str4 = "would have been loaded.";
if (verifyCorrectBrowser())
document.write(str1 + str3 + str4);
else
document.write(str1 + str2 + str3 + str4);
}

</SCRIPT>
</HEAD>
<BODY onload="getAppropriatePage()">
</BODY>
</HTML> | |
Here's the same page as it appears after being run through the Script Encoder:

After encoding, if you change even one character in the encoded text, the integrity of the entire script is lost and it can no longer be used. |
