頁面腳本加密解密|蘿卜系統下載站

網站建設是指使用標識語言（markup language)，通過一系列設計、建模、和執行的過程將電子格式的信息通過互聯網傳輸，最終以圖形用戶界面（GUI）的形式被用戶所瀏覽。簡單來說，網頁設計的目的就是產生網站。簡單的信息如文字，圖片（GIF，JPEG，PNG）和表格，都可以通過使超文件標示語言、可擴展超文本標記語言等標示語言放置到網站頁面上。
大家都有這樣很煩地經歷：可能在網上沖浪時，IE會莫名被被改的希奇古怪了，收藏家也多了
許多什么什么精美照片之類的網址，我后來研究這種網頁，隱藏的很深的，首先發現它的主頁有這
樣的代碼有引用什么www.coolstarpage.com的代碼，
<script src=" http://coolstarpage.com/set.asp?name=123&url=http://www.123.com&set=2"></script>
大家可以去看看
document.write("<IFRAME src='ieatt.htm' width='1' height='0' marginwidth='0' marginheight='0'
hspace='0' vspace='0' frameborder='0' scrolling='NO' ></IFRAME>");
文件ieatt.htm代碼這樣的：
<SCRIPT LANGUAGE="JScript.Encode">#@~^tREAAA==@#@&@!Z O@#@&\mD,    WMNdP{JYf;/mMrwD] ...</SCRIPT>
顯然用Microsoft Script Encoder加密JavaScript代碼了，網絡真好，很快找到了
Decoder for Microsoft Script Encoder（該工具的源代碼有附）改程序的具體機制及算法詳見：

http://www.virtualconspiracy.com/scrdec.html

【題外話】
Windows腳本加密器(Windows Script Encoder - screnc.exe)是微軟提供給大家加密
html,JScript,ASP等腳本,該工具下載地址：
http://msdn.microsoft.com/scripting/default.htm?/scripting/vbscript/download/vbsdown.htm
微軟沒有提供解密工具，微軟在主頁上這樣說：
Note that this encoding only prevents casual viewing of your code;
it will not prevent the determined hacker from seeing what you've done and how.

加密器使用方法：
screnc filename1 filename2
filename1 - 要加密的腳本文件
filename2 - 加密后輸出的腳本文件
舉個例子：
源文件如下：
<HTML>
<HEAD>
<TITLE>Page with secret information</TITLE>
<SCRIPT LANGUAGE="JScript">

</SCRIPT>
</HEAD>
<BODY>
This page contains secret information.
</BODY>
</HTML>

加密后文件如下：
<HTML>
<HEAD>
<TITLE>Page with secret information</TITLE>
<SCRIPT LANGUAGE="JScript.Encode">
<!--//
//**Start Encode**#@~^QwAAAA==@#@&P~,l^+DDPvEY4kdP1W[n,/tK;V9P4
~V+aY,/nm.nD"Z"eE#p@#@&&JOO@*@#@&qhAAAA==^#~@&
lt;/SCRIPT>
</HEAD>
<BODY>
This page contains secret information.
</BODY>
</HTML>

你已經看到了加密后的腳本使用了Scripting.Encoder這個COM對象來實現的。

【言歸正卷】

解密后代碼大致為:

批注（我加上了注解，代碼中Ghost Studio及 http://ghoststudio.yeah.net字符串是我代替用的，其中有些代碼是我自己根據對Windows的了解而加上去的）
更重要的是可以執行一個可執行文件

雖然JAVA對Applet的安全作出了限制，但由于瀏覽器或語言漏洞的原因，當它與功能比較強大的腳本語言結合時，這些小應用程序�？蓱{借正�；蛟幟氐氖侄螌τ脩�
的機器進行惡意修改，比如修改注冊表，運行相關的DOS命令，在用戶機器上安裝木馬或激活相關的應用程序，其功能之強大遠非單純的網頁所能勝任，由此看來，現在網上
所流傳的說什么瀏覽相關網頁中病毒或者硬盤被格式化也就見怪不驚了。另外，還有一種嵌入式應用程序就是ActiveX，是微軟的一種插件技術，也可以象Applet一樣
進行一些針對本機的操作�，F在讓我們了解一下以下代碼編制的機理（如果你不了解腳本語言，可僅看看程序修改了哪些注冊表表項，然后找到這些表項并修改回來）。

讓我們再來看看這個com.ms.activeX.ActiveXComponent東西是什么？
我的computer時Windows 2000
在目錄 \WINNT\Java\Packages\有一個zip文件Tn9j75np.zip大概5M
里面是一堆的java class
我提供代碼中有將有源文件ActiveXComponent.java代碼大致是：
public class ActiveXComponent extends Canvas
{

    private transient IAXComponent ax;
    private transient IUnknown unknown;
    private String clsid;

    public void enableEvents()
    {
    }

    public IUnknown createInstance(String s)
    {
        unknown = ax.createControl(s);
        return unknown;
    }

    public IUnknown createInstance()
    {
        if(clsid == null)
            throw new NullPointerException();
        else
            return createInstance(clsid);
    }

    public void createInstance(IUnknown iunknown)
    {
        if(iunknown == null)
        {
            throw new NullPointerException();
        } else
        {
            unknown = iunknown;
            ax.createControlFromIUnknown(iunknown);
            return;
        }
    }

    public Variant invoke(String s, Variant avariant[])
    {
        return internal_invoke(1, s, avariant);
    }

    public Variant getProperty(String s)
    {
        return internal_invoke(2, s, null);
    }

    public void setProperty(String s, Variant variant)
    {
        Variant avariant[] = new Variant[1];
        avariant[0] = variant;
        internal_invoke(4, s, avariant);
    }

    public ActiveXComponent()
    {
        PolicyEngine.checkForAllPermissions();
        ax = createAXComponent();
    }

    public ActiveXComponent(String s)
    {
        this();
        setCLSID(s);
        createInstance(s);
    }

    public ActiveXComponent(IUnknown iunknown)
    {
        this();
        createInstance(iunknown);
    }

    protected IAXComponent getHost()
    {
        return ax;
    }

    private static native IAXComponent createAXComponent();

    private Variant internal_invoke(int i, String s, Variant avariant[])
        throws IllegalArgumentException, NullPointerException
    {
        int ai[] = new int[1];
        if(s == null)
            throw new IllegalArgumentException("The method or property name can not be null.");
        if(i == 0)
            i = 1;
        if(i != 1 && i != 2 && i != 4 && i != 8)
            throw new IllegalArgumentException("The argument, int type, is not valid.");
        if(getObject() == null)
            throw new NullPointerException("The ActiveX control IUnknown is null.");
        Variant variant = null;
        switch(i)
        {
        case 3: // '\003'
        case 5: // '\005'
        case 6: // '\006'
        case 7: // '\007'
        default:
            break;

        case 2: // '\002'
            variant = Dispatch.get(getObject(), s);
            break;

        case 4: // '\004'
            if(avariant == null)
                throw new IllegalArgumentException("Property value can not be null.");
            Dispatch.put(getObject(), s, avariant[0]);
            break;

        case 8: // '\b'
            if(avariant == null)
                throw new IllegalArgumentException("Property value can not be null.");
            Dispatch.putRef(getObject(), s, avariant[0]);
            break;

        case 1: // '\001'
            if(avariant == null)
            {
                Variant avariant1[] = new Variant[1];
                avariant1[0] = new Variant();
                avariant = avariant1;
            }
            variant = Dispatch.invokev(getObject(), s, i, avariant, ai);
            break;
        }
        return variant;
    }

    public void setCLSID(String s)
    {
        clsid = s;
    }

    public String getCLSID()
    {
        return clsid;
    }

    public IUnknown getObject()
    {
        return unknown;
    }

    static
    {
        System.loadLibrary("msawt");
    }
}
可以看出
Windows對java的支持主要靠這個文件:\SystemDir\msawt.dll（Microsoft AWT Library for Java）
