标题: 用Javassist分析jeb.jar

关于jeb.jar，不知上下文而又对本文感兴趣的兄弟，参看:
http://bbs.pediy.com/showthread.php?t=189980
有人说没有看雪帐号，无法下载我破解的JEB 1.5，之前没有想到存在这个问题，以 为是开放式下载。放一份在这里:
jeb-1.5.201404100_modified_by_scz(20140711).7z http://pan.baidu.com/s/1o6E6xLo
把32-bits、64-bits的swt.jar一并打包进去了，与看雪论坛附件相比，没有实质变 化，无需重复下载。
jeb.jar的逆向工作其实已经阶段性中止了。有人提出能不能补上"Save As"功能，我 是业余时间看看，如果它的功能代码本来就存在的话，等我有时间就来补上，如果不 存在，以我的功力就不要指望太多了。
我最初是Eclipse、BTrace、JD-GUI、Source Insight相结合着把jeb.jar剁了，向诸 君推荐BTrace时抱怨过一句:
BTrace还是不够狠，不能修改参数和返回值，只能查看，可以调用public method，可 以直接修改public member，但仍受private的限制。如果这些都能解决该多好。
针对我这个抱怨，有人向我推荐了Javassist。怀着将信将疑的态度研究了一下 Javassist。
Javassist和BTrace的侧重不同，仔细测试前者之后感觉前者与后者可以互补。前者在 修改class方面足够强大，但在动态注入方面颇为鸡肋，它的HotSwapper实现远不如 BTrace实用，几乎是个演示性玩具。假设目标进程已经以jdwp方式启动，而Javassist 进程事后通过HotSwapper类Attach上去，reload()时会在reload2()中抛出 "failed to reload"异常。如果二者是合兵一处的，就可以reload()。
如果不考虑动态注入，Javassis确实是个NB工具，不是一般NB，是相当NB。不过要想 用爽它，建议还是把它自带教程完整读一遍，然后挨个实测。碰上各个类、方法时， 更应该看在线帮助:
http://www.csg.ci.i.u-tokyo.ac.jp/~chiba/javassist/html/javassist/
阅读其源码倒不是特别必要。不知为何大量介绍文章在演示最无聊的writeFile，个 人经验是，只要同时搜到Javassis和writeFile，这篇文章就不值得看，跳过。
扯远了，回到正题，用Javassist分析jeb.jar。我这次演示用Javassist如何修改 jebglobal.rP.dN(byte[] paramArrayOfByte,int paramInt1,int paramInt2)。这个 函数在解码被编码过的敏感字符串，比如"License key error."，你直接在反编译结 果中找不到这个明文字符串，它被编码后存放了。显然那些被编码过的敏感字符串就 是最好的路标，拦截rP.dN()，将它们找出来，再结合行号信息，就比较容易理清整个 流程。推荐作法是写BTrace脚本，自动跟踪rP.dN()，将执行路径上的敏感字符串都解 码还原出来，事实上我就是这样破解jeb.jar的。但我这不是被人忽悠到Javassist上 去了么，于是我就用Javassist重现了BTrace脚本的工作。
用Javassist重新实现了rP.dN()，根据需要，先输出调用栈回溯，再输出解码结果:
/*
- javac -g -cp "javassist.jar;jeb.xxx.jar" crack_jeb_o.java
- java -cp "javassist.jar;jeb.xxx.jar;." crack_jeb_o > crack_jeb_o.txt
- jeb.xxx.jar就是将jeb.jar中META-INF/下的JEBKEY.*删掉，再编辑一下
- MANIFEST.MF得到。否则java.lang.ClassLoader会在安全检查时抛出异常。
- javassist.Loader的安全检查要弱很多，可是它有别的缺陷导致不能用于此处。
- 最后用jeb.xxx.jar而不是jeb.orig.jar，纯属无奈之举。
- 仅为Java逆向之Javassist演示代码，非最终Loader。 / import javassist.; import jeb.Launcher;

不考虑CtClass.debugDump，crack_jeb_o.java实际就是个Loader，不会静态修改 jeb.xxx.jar。
