Microsoft 脚本编码器Script Encoder介绍（4）全中文

编码示例


如下是一个包含需要保护的 JScript 代码的简短示例
%26lt;HTML%26gt;
%26lt;HEAD%26gt;
%26lt;TITLE%26gt;脚本编码器示例页%26lt;/TITLE%26gt;
%26lt;SCRIPT LANGUAGE=%26quot;JScript%26quot;%26gt;
%26lt;!--//

//**开始编码**
function verifyCorrectBrowser(){
if(navigator.appName == %26quot;Microsoft Internet Explorer%26quot;)
if (navigator.appVersion.indexOf (%26quot;5.%26quot;) %26gt;= 0)
return(true);
else
return(false);
}
function getAppropriatePage(){
var str1 = %26quot;Had this been an actual Web site, a page compatible with %26quot;;
var str2 = %26quot;browsers other than %26quot;;
var str3 = %26quot;Microsoft Internet Explorer 5.0 %26quot;;
var str4 = %26quot;would have been loaded.%26quot;;
if (verifyCorrectBrowser())
document.write(str1 + str3 + str4);
else
document.write(str1 + str2 + str3 + str4);
}
//--%26gt;
%26lt;/SCRIPT%26gt;
%26lt;/HEAD%26gt;
%26lt;BODY onload=%26quot;getAppropriatePage()%26quot;%26gt;
%26lt;/BODY%26gt;
%26lt;/HTML%26gt;

该页在经脚本编码器运行后如下所示
%26lt;HTML%26gt;
%26lt;HEAD%26gt;
%26lt;TITLE%26gt;脚本编码器示例页%26lt;/TITLE%26gt;
%26lt;SCRIPT LANGUAGE=%26quot;JScript.Encode%26quot;%26gt;

%26lt;BODY onload=%26quot;getAppropriatePage()%26quot;%26gt;
%26lt;/BODY%26gt;
%26lt;/HTML%26gt;

要点经过编码后，假如您改动编码后的文本，哪怕只改动一个字。脚本的完整性就会丢失，从而不能再使用。
