JavaScript emoticon package encryption

  • after reading this article you may feel that you know nothing about the power of JavaScript!
  • let’s see what kind of encryption this is!
  • is the author of the encryption: from Japan Yosuke HASEGAWA
  • his project address: http://utf-8.jp/public/aaencode.html

    we encrypt a string of JS code with this method: alert(” HelloWorld! );

    function aaencode( text )
    {
        var t;
        var b = [
    		"(c^_^o)",

    		"((゚ー゚) + (゚Θ゚))",

    		"(゚Д゚) [゚Θ゚]"
            ];
    	var r = "゚ω゚ノ= /`m´)ノ ~┻━┻   //*´∇`*/ ['_']; o=(゚ー゚)  =_=3; c=(゚Θ゚) =(゚ー゚)-(゚ー゚); "; 
    	
    	if( /ひだまりスケッチ×(365|356)\s*来週も見てくださいね[!!]/.test( text ) ){
    		r += "X=_=3; ";
    		r += "\r\n\r\n    X/_/X < \"来週も見てくださいね!\";\r\n\r\n";
    	}
        r += "(゚Д゚) =(゚Θ゚)= (o^_^o)/ (o^_^o);"+

        for( var i = 0; i < text.length; i++ ){
            n = text.charCodeAt( i );
            t = "(゚Д゚)[゚ε゚]+";
    		if( n <= 127 ){
    			t += n.toString( 8 ).replace( /[0-7]/g, function(c){ return b[ c ] + "+ "; } );
    		}else{

    yes we got a bunch of cute memes!!

    however, these memes are not as cute as you might think, and they are just as damaging!!

    his corresponding decryption method is

    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);
    }
