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

Example

 CopyCode imageCopy Code
<HTML>
<HEAD>
<TITLE>Script Encoder Sample Page</TITLE>
<SCRIPT LANGUAGE="JScript">
<!--//
//Copyright© 1998 Microsoft Corporation. All Rights Reserved.
//**Start Encode**
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:

</SCRIPT>
</HEAD>
<BODY onload="getAppropriatePage()">
</BODY>
</HTML>
NoteNote

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.
