java 反編譯 android 反編譯

標籤：android   blog   http   io   os   ar   使用   java   for   

1. jad

http://varaneckas.com/jad/jad158e.linux.intel.zip  下載jad，

給jad運行許可權 ，運行

chmod a+x ./jad./jad

 缺點：不能反編譯混淆過的，有很多檔案反編譯不成功

2. ded

http://siis.cse.psu.edu/ded/installation.html

3. jd-gui

都知道這個，直接反編譯成java檔案，但是沒有命令列

4. jd-cmd

https://github.com/kwart/jd-cmd

其中需要安裝maven：http://maven.apache.org/download.cgi

linux安裝maven：

Extract the distribution archive, i.e. apache-maven-3.2.3-bin.tar.gz to the directory you wish to install Maven 3.2.3. These instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.2.3 will be created from the archive.In a command terminal, add the M2_HOME environment variable, e.g. export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.3.Add the M2 environment variable, e.g. export M2=$M2_HOME/bin.Optional: Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.Add M2 environment variable to your path, e.g. export PATH=$M2:$PATH.Make sure that JAVA_HOME is set to the location of your JDK, e.g. export JAVA_HOME=/usr/java/jdk1.7.0_51 and that $JAVA_HOME/bin is in your PATH environment variable.Run mvn --version to verify that it is correctly installed.

 

jd-cmd的使用：

程式本身給了3個例子：

Examples:$ java -jar jd-cli.jar HelloWorld.classShows decompiled class on a screen$ java -jar jd-cli.jar --skipResources -n -g ALL app.jarDecompiles app.jar to app.src.jar; It doesn‘t copy resources to the output jar,the decompiled classes contain line numbers as comments and the jd-cli printsthe most verbose debug information about decompilation$ java -jar jd-cli.jar myapp.jar -od decompiled -ocDecompiles content of myapp.jar to directory named ‘decompiled‘ and also on ascreen

 但是我執行第三個總是提示

19:47:27.494 WARN  jd.core.output.DirOutput - Class name or java source is null

 所以如果要反編譯class檔案，用第一個，要反編譯jar中的所有檔案，用第二個

5. jeb

商業版，據說功能很強大，有命令列和圖形，但是收費，執行速度慢，耗記憶體

使用：

java -Xmx1430m -jar jeb.jar --automation --script=JEBDecompileAll.py classes.dex啟動命令-Xmx 參數是指定java虛擬機器進程記憶體上限的JEBDecompileAll.py 這個Python指令碼裡調用了jeb的api，反編譯了所有的class檔案
