装一个swf decompiler就知道这个swf调用什么了，然后依法全部下载。 |

打开YV_YEP.swf看了看 还是看不懂
请那位高手来解说解说 这flashVars="id=13749435"该在哪里?
谢谢
package
{
import flash.display.*;
import flash.events.*;
import flash.net.*;
public class YV_YEP extends Sprite
{
private var _loader:Loader;
public function YV_YEP()
{
_loader = new Loader();
loaderInfo.addEventListener(Event.COMPLETE, onLoad);
return;
}// end function
private function onError(param1:Event) : void

发帖数: 26819 | 3 这种事我常遇到。
不要期望decompiler给你一个理想的结构，对于复杂的swf也不要希望拿到它全部的
东西，只要能看到代码，知道它的原理，自己能重新做一个就可以了。不可太贪。 |

如果你有swf decompiler看看源码就知道了。

发帖数: 6 | 10 现在有一个类的.class文件，想获得这个类定义的public methods。
使用下面的方法来做。但对于某些类，在运行到theClass.getMethods()时就出ClassNotF
oundException(而且不能被我程序的异常处理捕获，直接退出到命令行)，因为那个类引
用了一些在我的机器上没有的类。
//Class theClass=classLoader.loadClass(sClassName);
Class theClass=Class.forName(sClassName,false,classLoader);
allMethods=theClass.getMethods();
我的目的是只想得到这个类定义的所有公开功能，并不是要使用这个类。
（当然可以用decompiler去看，但我要处理大量的类，想通过程序做）
应该有办法获得吧，就象IDE可以列出类的所有功能。
请指教。谢谢！ |

发帖数: 312 | 12 use retro guard:
Java bytecode (.class and .jar files) contains much of the information in your
Java source files, leaving your products exposed to reverse engineering.
RetroGuard, a general purpose bytecode obfuscator, is designed to fit
effortlessly into your regular build and testing process, providing peace of
mind that your valuable Java code is more secure against decompilation and
other forms of reverse engineering.

发帖数: 1422 | 13 I have this stupid thought: why we need to do that?
(1)java means to be open source, isn't it?
(2)maybe I am not good enough, but I always think that anything I can do,
there're whole lot people can do it too (maybe even better) without look at my
code
(3)if your product needs protection, I think it's going to be complex enough,
do you think one can spend less time to redo it by reading the decompiled code
without design doc and spec doc, than redo it from scratch (if they know the
reqirements) |

There is no way. You can only obfuscate your class files so people
cannot decompile. |

This is the top skill a java dev needs, know how to efficiently use
google and copy/paste. |

I wonder how flash player deals with this - we never see security warnings
from playing a flash.
That probably can't be helped - java classes can be decompiled, if someone
really wants it. |

are you worried about your encryption algorithm being decompiled and

发帖数: 19 | 28 It is very likely it can be done -- since even the jar file may be
decompiled to the source code (the code might be obfuscated. It can be hard
to figure out the thing). But if you are not familar with Java, you are
pretty much out of the luck to take such an adventure.

发帖数: 14569 | 38 But for most developer, they don't need to decompile code. Besides, a bad/
long program is automatic obfuscated, nobody wants to read/understand such
code unless he is the unlucky maintainer. |

发帖数: 3271 | 39 That's because you confuse Java language vs JVM byte code. They are not the
same by specification and JVM byte code can have a lot of illegal Java
constructs.
In fact today's best obfuscator utilizes this, for instance, directly write
a compiled byte code to replace Java names with weird illegal characters to prevent
decompiling.
Back to the question, I think LZ simply made a wrong observation during compiling. The class can be compiled but the caller will have problem if no Generic parameters a... 阅读全帖 |
