HTML防盗

Question

我正在设计一个网站,我想确保没有人可以窃取代码.我想阻止代码被从网站中删除,并在用户尝试这样做时显示错误消息.

HTML Obfuscation是一种转换工具,它既可以保留代码,也可以防止它被反向工程.你可以在这里找到更多相关信息.

以下是混淆代码的示例.

这是非常简单的HTML代码:

<a href="mailto:someone@domain.com">Mail me</a>

这可以变成这样:

<script type="text/javascript">
<!--
var s="=b!isfg>#nbjmup;tpnfpofAepnbjo/dpn#?Nbjm!nf=0b?";
m=""; for (i=0; i<s.length; i++).m+=String.fromCharCode(s.charCodeAt(i)-1); document.write(m);
//-->
</script>
<noscript>
&#13&#10&#60&#97&#32&#104&#114&#101&#102&#61&#34&#109&#97&#105&#108&#116&#111&#58&#115&#111&#109&#101&#111&#110&#101&#64&#100&#111&#109&#97&#105&#110&#46&#99&#111&#109&#34&#62&#77&#97&#105&#108&#32&#109&#101&#60&#47&#97&#62
</noscript>

这称为Combined混淆.

<script type="text/javascript">
<!--
var s="=b!isfg>#nbjmup;tpnfpofAepnbjo/dpn#?Nbjm!nf=0b?";
m=""; for (i=0; i<s.length; i++) m+=String.fromCharCode(s.charCodeAt(i)-1); document.write(m);
//-->
</script>
<noscript>
You must enable JavaScript to see this text.
</noscript>

这称为JavaScript混淆.

&#13&#10&#60&#97&#32&#104&#114&#101&#102&#61&#34&#109&#97&#105&#108&#116&#111&#58&#115&#111&#109&#101&#111&#110&#101&#64&#100&#111&#109&#97&#105&#110&#46&#99&#111&#109&#34&#62&#77&#97&#105&#108&#32&#109&#101&#60&#47&#97&#62&#13&#10

这称为Character Entities混淆.

所有这些方法在该网站上完全免费,并允许您将所有代码保密.

编辑:

经过进一步的研究,我找到了另一个网站,JSF**K,它允许您使用一系列括号,括号,感叹号和加号来编码项目.下面是它如何编码一个简单的项目:

alert(1)

变为:

[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]][([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+([][[]]+[])[+!+[]]+(![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[+!+[]]+([][[]]+[])[+[]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+(!![]+[])[+!+[]]]((![]+[])[+!+[]]+(![]+[])[!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]+(!![]+[])[+[]]+(![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[!+[]+!+[]+[+[]]]+[+!+[]]+(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[!+[]+!+[]+[+[]]])()

这几乎是不可能破解的,因为您需要使用数据"模糊"网站以获取字符代码,然后使用正则表达式来构建解码器.
