黑羽翔天 § Kingda's Weblog: AS3反编译器快要露脸了

AS3反编译器快要露脸了

ActionScript3天地会公测中...

自从Adobe贡献源码给Tamarin后，AS3 decompiler一直在传言中。
居然有位兄台写出了如何做AS3 decompiler，有趣有趣
虽然只是初步，但毕竟是个开始，大家瞧好吧

例子：破解前的源码



public class RawAmfService extends EventDispatcher

{

        public var gatewayUrl:String = "";

        var loader:URLLoader;

       

        public function RawAmfService()

        {

                loader = new URLLoader();

                loader.addEventListener('complete', readData);

        }

        ...

}

反编译后的代码：



class RawAmfService extends flash.events::EventDispatcher

{

        var gatewayUrl:String = ""        /* slot_id 0 */

        var loader:flash.net::URLLoader        /* slot_id 0 */

        function RawAmfService():*        /* disp_id -1*/

        {

                // local_count=1 max_scope=1 max_stack=3 code_len=40

                0     getlocal0            

                1     pushscope            

                2     findproperty          gatewayUrl

                5     pushstring            ""

                7     initproperty          gatewayUrl

                10    getlocal0            

                11    constructsuper        (0)

                13    findproperty          loader

                16    findpropstrict        flash.net::URLLoader

                19    constructprop         flash.net::URLLoader (0)

                23    initproperty          loader

                26    getlex                loader

                29    pushstring            "complete"

                32    getlex                readData

                35    callpropvoid          addEventListener (2)

                39    returnvoid           

        }

        ...

}
