JavaScript 表情包加密

• 阅读完本文后你可能会感觉到你对 JavaScript 的力量一无所知!
• 下面来看看这是一种什么样的加密方式吧!
• 该加密方式的作者是来自日本的：Yosuke HASEGAWA

我们通过该方法 加密一串 JS 代码: alert(“HelloWorld!”);

是的我们得到了一堆可爱的表情包!!!

然而这些表情包可没有你想象的那么可爱，他也同样具有杀伤力!!!

他对应的解密方法为

function decrypt (text) {
	var evalPreamble = "(\uFF9F\u0414\uFF9F) ['_'] ( (\uFF9F\u0414\uFF9F) ['_'] (";
	var decodePreamble = "( (\uFF9F\u0414\uFF9F) ['_'] (";
	var evalPostamble = ") (\uFF9F\u0398\uFF9F)) ('_');";
	var decodePostamble = ") ());";

	// strip beginning/ending space.
	text = text.replace(/^\s*/, "").replace(/\s*$/, "");

	// returns empty text for empty input.
	if (/^\s*$/.test(text)) {
		return "";
	}
	// check if it is encoded.
	if (text.lastIndexOf(evalPreamble) < 0) {
		throw new Error("Given code is not encoded as aaencode.");
	}
	if (text.lastIndexOf(evalPostamble) != text.length - evalPostamble.length) {
		throw new Error("Given code is not encoded as aaencode.");
	}

	var decodingScript = text.replace(evalPreamble, decodePreamble)
							 .replace(evalPostamble, decodePostamble);
	return eval(decodingScript);
}
