2001-08-12 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/obfuscator/Identifier.java.in (writeTable): New boolean |
||||
parameter specifying if reversed or not. |
||||
* jode/obfuscator/ClassBundle.java.in: Renamed the table file |
||||
variables, added outTableFile. |
||||
(setOption): Support outtable, intable and outrevtable. |
||||
Support verbose. |
||||
(writeTable): Writes table unreversed. |
||||
(writeRevTable): New method, Writes table reversed. |
||||
* jode/obfuscator/Main.java.in: (rand): New variable. |
||||
* jode/obfuscator/PackageIdentifier.java.in: Use Main.rand instead |
||||
of definining its own random. |
||||
* jode/obfuscator/ClassIdentifier.java.in: likewise. |
||||
|
||||
* jode/flow/FlowBlock.java.in: |
||||
(checkConsistent): Allow lastModified in a finally block. |
||||
|
||||
* jode/flow/TransformExceptionHandlers.java.in: Reworked exception |
||||
handlers again. This time checked with javac 1.3, javac 1.1 and |
||||
jikes. |
||||
(checkTryCatchOrder): New method that was previously part of |
||||
analyze. |
||||
(analyze): Use checkTryCatchOrder. Don't merge try and catch flow |
||||
blocks anymore, leave it to the analyzeXXX methods. |
||||
(mergeTryCatch): New method. |
||||
(analyzeCatchBlock): Get catchFlow as parameter. Call |
||||
mergeTryCatch. |
||||
(transformSubroutine): Handle POP-only subroutines. |
||||
(removeJSR): Don't do special case for catchBlock any more. This |
||||
is because catchFlow isn't yet merged when this method is called. |
||||
(checkAndRemoveJSR): Likewise. |
||||
(checkAndRemoveMonitorExit): Likewise. Merge subroutine only if |
||||
we are the only predecessor. |
||||
(analyzeSynchronized): Get catchFlow as parameter. Call |
||||
mergeTryCatch. |
||||
(mergeFinallyBlocks): New method, calls mergeTryCatch and does the |
||||
common part of mergeFinally and mergeSpecialFinally. |
||||
(analyzeFinally): Simplified, after checking and removing JSR, it |
||||
does immediately analyze and transform subroutine to get the |
||||
finallyBlock. Then it throws away the catchFlow and calls |
||||
mergeFinallyBlocks. |
||||
(analyzeSpecialFinally): Simplified, after checking it only handles |
||||
the jumps in the try part and then call mergeFinallyBlocks. |

good and removeJSR will finally remove them. |

call lhs.dumpExpression() with priority. |
||||
* jode/expr/PrePostFixOperator.java (dumpExpression): likewise. |
||||
* jode/expr/IIncOperator.java (dumpExpression): likewise. |
||||
* jode/flow/TransformConstructors.java (jikesAnonInner): Removed, |
||||
since it wasn't used: This information is stored in OuterValues |
||||
now. |
||||
* jode/decompiler/LocalInfo.java (isConstant): Always return true |
||||
so that inner classes that access final locals work, even if we |
||||
can't decide that the local can be final. |
||||
|
||||
2001-02-05 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/expr/InvokeOperator.java.in (Environment.invokeMethod): |
||||
Fixed the call to ClassInfo.forName: it expects a class name, while |
||||
ref.getClazz() gives a type signature. |
||||
* jode/flow/TransformExceptionHandlers.java.in: |
||||
(checkAndRemoveJSR): Only invoke removeBadJSR, if there are |
||||
successors left. |
||||
(checkAndRemoveMonitorExit): likewise. |
||||
|
||||
2001-02-04 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/expr/IfThenElseOperator.java (simplify): Allow in the class$ |
||||
simplification the then and else part to be swapped. |
||||
* jode/bytecode/ClassInfo.java.in (read): Accept class version |
||||
1.3. |
||||
* jode/type/ClassInterfacesType.java (keywords): Added the package |
||||
and import keywords. |
||||
* jode/flow/TransformExceptionHandlers.java.in: |
||||
(getPredecessor): New function. |
||||
(getMonitorExitSlot): New function. |
||||
(skipFinExitChain): New function. |
||||
(removeJSR): Replaced by ... |
||||
(removeBadJSR): ... this. |
||||
(checkAndRemoveJSR): Use the new functions. Much simpler and |
||||
handles nested synchronized blocks. It now traces the whole JSR |
||||
and monitorexit chain before a jump to the first entry via |
||||
skipFinExitChain, then checks and remove the first JSR |
||||
resp. monitorexit. JSR jumps are simply ignored now. |
||||
(checkAndRemoveMonitorExit): likewise. |
||||
* jode/flow/StructuredBlock.java.in (prependBlock): New function. |
||||
* jode/flow/CatchBlock.java.in (makeDeclaration): Generate name |
||||
of dummyLocal, since nobody else will generate it. |
||||
|
||||
2001-02-03 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/bytecode/BytecodeInfo.java.in (read): Remove bogus |
||||
exceptionHandlers, whose catchers just throw the exception again. |
||||
This kind of entries are inserted by an obfuscator and would break |
||||
JODE. |
||||
* jode/util/UnifyHash.java.in (iterateHashCode): Call cleanUp, |
||||
to clean unneeded references. |
||||
* jode/flow/TransformConstructors.java (transformOneField): |
||||
Changed to private. Take field number as parameter. Check that |
||||
expression doesn't contain a FieldOperator for a later field of |
||||
the same class or a PutFieldOperator. Changed all callers. |
||||
|
||||
2001-02-01 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/jvm/CodeVerifier.java.in (Type.mergeType): If array elem |
||||
types can't be merged, return tObject as common super type. |
||||
* jode/type/ArrayType.java (getGeneralizedType): If array elem |
||||
type can't be intersected, return tObject as common super type. |
||||
* jode/flow/TransformExceptionHandlers.java.in: Merged patch from |
||||
the 1.2 tree to support javac 1.3 synchronized blocks. Doesn't |
||||
handle nested synchronized blocks yet. |
||||
* jode/expr/Expression.java.in (dumpExpression): Show runtime |
||||
exception when it occurs. |
||||
|
||||
2001-01-31 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/expr/Expression.java.in (updateParentTypes): Call setType, |
||||
instead of merging the types. Other childs want to know about the |
||||
type change as well. |
||||
* jode/decompiler/LocalInfo.java (combineWith): Reorganized a bit, |
||||
but no changes. |
||||
* jode/expr/InvokeOperator.java.in (dumpExpression): Always print |
||||
the ThisOperator if a field is from a parent class of an outer |
||||
class is used. And always qualify the this operator if not |
||||
innermost. |
||||
|
||||
2001-01-30 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/jvm/SyntheticAnalyzer.java.in (checkConstructorAccess): |
||||
Allow the special unifyParam to be the last parameter. |
||||
|
||||
2001-01-30 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/decompiler/TabbedPrintWriter.java: Better gnu style handling: |
||||
(openBraceClass) (closeBraceClass) |
||||
(openBraceNoIndent) (closeBraceNoIndent): new functions. |
||||
(closeBraceNoSpace): Removed. |
||||
* jode/decompiler/Options.java (GNU_SPACING): new constant. |
||||
(GNU_STYLE): changed to include GNU_SPACING. |
||||
* jode/decompiler/ClassAnalyzer.java.in (dumpSource): Use |
||||
open/closeBraceClass. |
||||
* jode/decompiler/MethodAnalyzer.java.in (dumpSource): Use |
||||
open/closeBraceNoIndent. Insert a space for GNU_SPACING. |
||||
* jode/decompiler/InvokeOperator.java.in (dumpExpression): Insert |
||||
a space for GNU_SPACING, use open/closeBraceClass for inner |
||||
classes. |
||||
* jode/decompiler/UnaryOperator.java (dumpExpression): Insert |
||||
a space for GNU_SPACING. |
||||
|
||||
2001-01-30 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
Added pascal style from Rolf Howarth <rolf@squarebox.co.uk> |
||||
* jode/decompiler/Options.java (PASCAL_STYLE): new constant. |
||||
(BRACE_FLUSH_LEFT): dito. |
||||
* jode/decompiler/Decompiler.java (setOption): detect pascal option. |
||||
* jode/decompiler/Main.java (main): dito. |
||||
* jode/decompiler/TabbedPrintWriter.java (openBrace, |
||||
openBraceContinue, closeBrace, closeBraceNoSpace, |
||||
closeBraceContinue): handle flush left. |
||||
|
||||
2001-01-30 Jochen Hoenicke <jochen@gnu.org> |
||||
|
||||
* jode/type/NullType.java (intersection): Removed, since the |
||||
version in ReferenceType is more correct. Before |
||||
tNull.isOfType(tRange(X,tNull)) returned false, which lead to |
||||
incorrect behaviour in InvokeOperator.needsCast. |
||||
* jode/decompiler/FieldAnalyzer.java.in (dumpSource): Removed the |
||||
"= null" hack for final fields; it was not correct, since the |
||||
field could be initialized in a constructor. |
||||
* jode/decompiler/TabbedPrintWriter.java (BreakPoint.endOp): |
||||
Simplified the code, copy options always from child. |
||||
* jode/jvm/SyntheticAnalyzer.java.in (unifyParam): new field. |
||||
(checkConstructorAccess): Allow the special Parameter, whose |
||||
purpose is to distinguish the wrapper from the real constructor |
||||
and give him a "$" in the type signature, to appear at every |
||||
position. It doesn't appear at position 1 for inner classes. |
||||
Store the position in unifyParam. |
||||
* jode/expr/InvokeOperator.java (isGetClass): Allow the method to |
||||
be declared inside an outer class: We simply check if we can get |
||||
the method analyzer. |
||||
(simplify): handle unifyParam. |
||||
* jode/expr/PopOperator.java (getBreakPenalty): return penalty of |
||||
inner expression. (dumpExpression): Call dumpExpression of |
||||
subexpression immediately without priority. |

<p>If java gets called with `<code>-O</code>' switch, it inlines methods, |
||||
that are private, final, or static and contain no loops. When |
||||
decompiling this it sometimes produces really ugly code. The right |
||||
way to solve this would be to <i>out</i>line the code again. This is |
||||
possible but requires to find the inlined method. </p> |
||||
|
||||
<p>The name `outline' was suggested by <a |
||||
href="http://www.informatik.uni-oldenburg.de/~mw">Michael</a>. |
||||
</p> |
||||
|
||||
<h2>Better names of local variables</h2> |
||||
|
||||
<p>The local variable naming is very stupid. Even with pretty it just |
||||
names the variable after the type with a unifying number appended. A |
||||
method containing very much objects of the same type looks very |
||||
ugly. </p> |
||||
|
||||
<p>My plan is looking at the assignments. If we have locals in |
||||
assignments |
||||
<pre> |
||||
int l_1 = array.length |
||||
String l_2 = object.getName() |
||||
</pre> |
||||
we could name them "length" and "name". If we |
||||
have assignments: |
||||
<pre> |
||||
MenuItem local_1 = new MenuItem("Open"); |
||||
MenuItem local_2 = new MenuItem("Save"); |
||||
</pre> |
||||
good names would be <code>miOpen</code> and <code>miSave</code>. </p> |
||||
|
||||
<p>It is currently possible to assign a <i>(hint name,type)</i> pair |
||||
to a local. If the type matches, the local will be named after |
||||
<i>hint name</i>. This could be extended by giving them several |
||||
weighted hints and constructing the name in an intelligent way. </p> |
||||
|
||||
<h2>Better deobfuscation features</h2> |
||||
<p>First there should be a good Renamer: Methods that simply |
||||
return a field value should be renamed to get<i>FieldName</i>. |
||||
Fields should be named after their type, maybe also by assignments |
||||
(see section about local variable names).</p> |
||||
|
||||
<p>The deobfuscator should detect inner and anonymous variables, |
||||
synthetic methods and so on, and rename them accordingly.</p> |
||||
|
||||
<h2>Handling of Class.forName in obfuscator</h2> |
||||
<p>The obfuscator should detect Class.forName constructs (and |
||||
similarly for methods and fields) and if their parameters are constant |
||||
it should change the parameter according to the rename function. </p> |
||||
|
||||
<h2>Merging javadoc comments</h2> |
||||
<p>It would be nice if the decompiler could merge the javadoc comments |
||||
into the class file. More and more people use javadoc to comment the |
||||
public api of their java classes. It shouldn't be too difficult to |
||||
copy them back into the java code. </p> |
||||
|
||||
<p>This doesn't need to be built into the decompiler. A script that takes |
||||
the javadoc pages and the decompiled code can easily merge them.</p> |

<h1>FAQ - Frequently Asked Questions</h1> |
||||
|
||||
This is a list of some questions that pop up from time to time. |
||||
|
||||
<h2>Decompiler issues</h2> |
||||
|
||||
<h3>The decompiler crashes with a VerifyException, what can I do?</h3> |
||||
|
||||
<p>The class isn't verifiable, probably because there is not enough |
||||
information about used classes. See the question about the |
||||
classpath.</p> |
||||
|
||||
<p>This could also be caused by malicious bytecode, or because there |
||||
is a bug in Jode's verifier.</p> |
||||
|
||||
<h3>What should be included in the classpath?</h3> |
||||
|
||||
<p>Jode needs to know the full class hierarchie to guess the types. |
||||
This includes not only the classes in the program, but also the |
||||
libraries used by the java program, even the Java runtime library. |
||||
You should set the classpath to include all these classes.</p> |
||||
|
||||
<p>If you don't specify the classpath on the command line, Jode uses |
||||
the same as your Java Virtual Machine.</p> |
||||
|
||||
<p>As last resort, if Jode can't find a class in the classpath it uses |
||||
reflection to ask the Virtual Machine. This works quite well, but |
||||
loading classes can have side effects, e.g. when AWT classes are |
||||
loaded, an AWT thread is created, even though Jode doesn't need |
||||
it.</p> |
||||
|
||||
<h3>Why doesn't Jode decompile my inner class |
||||
<code>MyClass$Inner.class</code>?</h3> |
||||
|
||||
<p>You should decompile the outermost class (<code>MyClass</code> in |
||||
this case). The produced code contains the inner class. </p> |
||||
|
||||
<h2>Obfuscator issues</h2> |
||||
|
||||
<h3>What should be included in the classpath?</h3> |
||||
|
||||
<p>The program, all libraries, the Java runtime library. Don't omit a |
||||
library even when you don't want to obfuscate it.</p> |
||||
|
||||
<h3>What should I preserve</h3> |
||||
|
||||
<p>The most common mistake is to preserve a class. In most cases this |
||||
is not what you want. This only makes sure the class won't be |
||||
renamed, it doesn't prevent it from being stripped. Instead you |
||||
should preserve methods and constructors. The constructor is just a |
||||
method with the special name <tt><init&rt;</tt>. </p> |
||||
|
||||
<p> Another common mistake is to omit the type |
||||
signature, e.g. to preserve <tt>Class.main</tt> instead of |
||||
<tt>Class.main.([Ljava/lang/String;)V</tt>. That doesn't work. If |
||||
you don't want to care about the format of the type signature use a |
||||
wildcard as in <tt>Class.main.*</tt>. </p> |
||||
|
||||
<h3>What is a type signature</h3> |
||||
|
||||
<p>The type signature is a machine readable representation of a java |
||||
type that is used all over in java bytecode. The JDK ships a command |
||||
named <tt>javap</tt>. With <tt>java -s</tt> you can lists the fields |
||||
and methods of a class with their type signatures.</p> |
||||
|
||||
<p> If you are interested in the format of type signatures read the |
||||
Java Virtual Machine Specification, Chapter 4.3 Descriptors</p> |

<h2>History</h2> |
||||
|
||||
<p>Someday I found <code>guavad</code>, a disassembler for java byte |
||||
code (it does similar things like <code>javap -c</code>). I used |
||||
it on a class file, and found that it was possible to reconstruct the |
||||
original java code. First I did it by hand on some small routines, |
||||
but I soon realized that it was a rather stupid task. So I wrote a |
||||
small <a href="dasm_to_java.perl"><code>perl</code> script</a> that |
||||
did this process automatically. At the end of the next day I had my |
||||
first working decompiler.</p> |
||||
|
||||
<p>Now while the <code>perl</code> script is working, it is not easy |
||||
to use. You have to decompile the code first with a disassembler, cut |
||||
out the code of a single method, and run the perl script on it. I |
||||
decided to get the bytecode directly out of the class files and do |
||||
this all automatically. I decided to write it in <code>java</code> |
||||
now, because it suited best.</p> |
||||
|
||||
<p>Just for the records: the java code is now more than 50 times |
||||
bigger than the original perl script and is still growing.</p> |

<P><i>JODE</i> is a java package containing a decompiler and an |
||||
optimizer for java. This package is freely available under the GPL |
||||
(see <a href="./license.html">license</a>).<p> |
||||
|
||||
<P>The decompiler takes <tt>class</tt> files as input and produces |
||||
something similar to the original <tt>java</tt> file. Of course this |
||||
can't be perfect: There is no way to produce the comments or the names |
||||
of local variables (except when compiled with debuging) and there are |
||||
often more ways to write the same thing. But <i>JODE</i> does its job |
||||
quite well, so you should give it a try: <a href="./applet.html">start |
||||
the applet</a>.</P> |
||||
|
||||
<P>The optimizer transforms <tt>class</tt> files in various ways with |
||||
can be controlled by a script file. It supports the following |
||||
operations:</p> |
||||
<ul> |
||||
<li>Renaming class, method, field and local names to shorter, |
||||
obfuscated, or unique names or according to a given translation |
||||
table</li> |
||||
<li>Removing debugging information</li> |
||||
<li>Removing dead code (classes, fields, methods) and constant |
||||
fields</li> |
||||
<li>Optimizing local variable allocation</li> |
||||
</ul> |
||||
|
||||
<h2>News</h2> |
||||
|
||||
<ul> |
||||
<li><i>JODE</i> is now hosted by <a href="http://sourceforge.net/">SourceForge</a>.</li> |
||||
<li>The latest <a href="http://sourceforge.net/cvs/?group_id=3790">CVS</a> version breaks long lines</li> |
||||
<li>I can now decompile <b>inner and anonymous</b> classes.</li> |
||||
<li>The optimizer (aka obfuscator) can be customized via a small |
||||
config file</li> |
||||
<li>Jode is <tt>autoconf</tt>igured.</li> |
||||
</ul> |
||||
|
||||
<h2>Limitations</h2> |
||||
|
||||
<p>If not all dependent classes can be found, the verifier (which is |
||||
run before decompilation starts) may exit with a type error. You |
||||
can decompile it with <tt>--verify=off</tt>, but take the warning |
||||
serious, that types may be incorrect. There's sometimes no way to |
||||
guess the right type, if you don't have access the full class |
||||
hierarchie.<br> |
||||
|
||||
This is not a bug in the verifier: java will complain the same way, |
||||
if it is run with bytecode verification turned on. And if you don't |
||||
have the dependent classes, you can't compile the code again.</p> |
||||
|
||||
<p>There may be situations, where the code doesn't understand complex |
||||
expressions. In this case many ugly temporary variables are used, but |
||||
the code should still be compileable. This does especially happen |
||||
when you compile with <tt>`-O'</tt> flag and javac has inlined some |
||||
methods. </p> |
||||
|
||||
<p>Sometimes this program may exit with an <code>Exception</code> or |
||||
produce incorrect code. Most time the code can't be compiled, so that |
||||
it can be easily spotted. If you have one of these problems (except |
||||
those that occur on some of the <code>jode.test</code> files, I would |
||||
be very interested in a bug report (including the <code>class</code> |
||||
file, if possible). </p> |
||||
|
||||
<p>Sometimes <i>JODE</i> generates some GOTO expression and labels. |
||||
This shouldn't happen any more with code produced by javac or jikes. |
||||
But some flow obfuscator may provoke this. In that case you can run |
||||
the Obfuscator first (to optimize away the flow obfuscation ;-).</p> |

||||
<h1>Using the Decompiler</h1></a> |
||||
After you have <a href="./download.html">downloaded</a> the necessary |
||||
packages, put them into your <tt>CLASSPATH</tt>: |
||||
|
||||
<ul><li>Under Windows you have to start a MSDOS session and type |
||||
something like: |
||||
<pre> |
||||
set CLASSPATH=C:\download\jode-xxx.jar;C:\swing\swingall.jar |
||||
</pre> |
||||
</li><li>Under Unix you start a shell and type (for bourne shell): |
||||
<pre>export CLASSPATH=/tmp/jode-xxx.jar:/usr/local/swing/swingall.jar</pre> |
||||
or for csh: |
||||
<pre>setenv CLASSPATH /tmp/jode-xxx.jar:/usr/local/swing/swingall.jar</pre> |
||||
</ul> |
||||
<br> |
||||
There is also a batch file for windows and a script file for unix, |
||||
that you can use. Adapt the CLASSPATH in the file and put it to a |
||||
convenient location. |
||||
<pre> |
||||
jar -xvf jode-xxx.jar bin/jode.bat <i>resp.</i> bin/jode |
||||
</pre> |
||||
|
||||
<a name="cmdline"><h3>Command Line Interface</h3></a> |
||||
|
||||
The most powerful way to start <I>JODE</I>'s decompiler is the command |
||||
line interface. Some people don't like long command lines; they |
||||
should go to the next section. <br> |
||||
|
||||
Start the class <tt>jode.decompiler.Main</tt> with the options. The |
||||
following command will give a complete list of the available commands: |
||||
|
||||
<pre>java jode.decompiler.Main --help</pre> |
||||
|
||||
<a name="awt"><h3>AWT Interface</h3></a> |
||||
|
||||
The AWT Interface looks exactly like the <a href="./applet.html">applet</a>. In fact the applet uses the AWT Interface. You start it |
||||
after setting the <tt>CLASSPATH</tt> (see <a href="./usage.html#decompiler">above</a>), with |
||||
|
||||
<pre>java jode.decompiler.Window</pre> |
||||
|
||||
In the classpath line you can enter a number of jar files, zip files |
||||
and directories separated by comma(<tt>,</tt>). Then enter the |
||||
dot(<tt>.</tt>) separated name of the class you want to decompile. |
||||
Press the <code>start</code> button and the decompiled class should |
||||
appear. You can save it via the <code>save</code> button. |
||||
|
||||
<a name="swing"><h3>Swing Interface</h3></a> |
||||
|
||||
For the swing interface you need java version 1.2 or the separately |
||||
available swing package (see <a href="./links.html#swing">link |
||||
page</a>. You can invoke it like this: |
||||
<pre> |
||||
java jode.swingui.Main --classpath classes.jar |
||||
</pre> |
||||
|
||||
The swing interface will show the package hierarchie of all classes |
||||
in the classpath on the left side. You can now select a class and the |
||||
decompiled code will appear on the right side. Via the menu, you may |
||||
change the classpath or switch between package hierarchie tree and |
||||
class inheritence tree.<br> |
||||
|
||||
The swing interface is very useful to browse through class files if |
||||
you don't have the source code. You can also use it to trace bugs in |
||||
library code. It is not meant to generate <tt>java</tt> files and so |
||||
you won't find a save option there.<br> |
||||
|
||||
<a name="java"><h3>Java Interface</h3></a> |
||||
|
||||
If you want to integrate <i>JODE</i> into your own java program, you |
||||
can use the <a |
||||
href="Decompiler.java"><code>jode.decompiler.Decompiler</code></a> |
||||
class. Note that the GPL only allows you to integrate <i>JODE</i> |
||||
into GPL programs. Please contact me if you use <i>JODE</i> in this |
||||
way.<br> |
||||
|
||||
You may use this <a |
||||
href="ftp://jode.sourceforge.net/pub/jode/jode-embedded.jar">stripped |
||||
down jar archive</a> containing all necessary classes. |
||||
|
||||
<a name="optimizer"><h1>Using the Obfuscator</h1> |
||||
|
||||
To use the obfuscator you should first create a script file, say <a |
||||
href="myproject.jos"><tt>myproject.jos</tt></a>. Then you can invoke the |
||||
obfuscator with: |
||||
<pre> |
||||
java jode.obfuscator.Main myproject.jos |
||||
</pre> |
||||
|
||||
<p>The script file should contain the following options: </p> |
||||
|
||||
<p>First select the classpath. You should include everything in the |
||||
classpath that you need to run your application. This also includes |
||||
the system class files (Sun puts them into <code>classes.zip</code> or |
||||
<code>rt.jar</code>))</p> |
||||
<pre> |
||||
classpath = "c:\\jdk1.2\\jre\\lib\\rt.jar","d:\\project\\java", |
||||
"ftp://www.myorg.org/pub/classlib.jar" |
||||
</pre> |
||||
|
||||
<p>Specify where you want the obfuscated classes to go. I recommend |
||||
to write them directly into a zip file, but you can also give a |
||||
directory.</p> |
||||
<pre> |
||||
dest = "obfuscated.zip" |
||||
</pre> |
||||
|
||||
<p>You can make <i>JODE</i> write its translation table. This table |
||||
can be used later to undo the name obfuscation, or you can look there |
||||
to decrypt exceptions you may get.</p> |
||||
<pre> |
||||
revtable = "translat.tbl" |
||||
</pre> |
||||
|
||||
<p>Select what you want to strip. There are several |
||||
possibilities, which can be separated by comma(<tt>,</tt>):</p> |
||||
<dl> |
||||
<dt>unreach</dt> |
||||
<dd>strip unreachable methods and classes.</dd> |
||||
<dt>source</dt> |
||||
<dd>remove the name of the java file (exceptions will get unreadable).</dd> |
||||
<dt>lnt</dt> |
||||
<dd>remove the line number table (exceptions will get unreadable).</dd> |
||||
<dt>lvt</dt> |
||||
<dd>remove the local variable table (debugging doesn't work).</dd> |
||||
<dt>inner</dt> |
||||
<dd>strip inner class info (reflection doesn't work correctly).</dd> |
||||
</dl> |
||||
<pre> |
||||
strip = "unreach","lvt","inner" |
||||
</pre> |
||||
|
||||
<p>Select the packages and classes you want to obfuscate. You should |
||||
only include libraries, that you don't ship separately. If you give a |
||||
package, all classes and subpackages are loaded. You can also use |
||||
<code>*</code> as wild card, that matches everything (including dots). |
||||
</p> |
||||
<pre> |
||||
load = new WildCard { value = "org.myorg.myproject" }, |
||||
new WildCard { value = "org.myorg.mylib*" }, |
||||
new WildCard { value = "org.otherorg.shortlib" } |
||||
</pre> |
||||
|
||||
<p>Select the methods and classes you want to preserve. This is |
||||
the <tt>main</tt> method for applications and the default constructor |
||||
<tt><init>.()V</tt> for applets, resource bundles and other classes |
||||
that you load manually at runtime.<br> You have to give the method |
||||
name and the type signature to identify your method. <tt>javap |
||||
-s</tt> will show you the type signatures for your classes, but you |
||||
may also use <tt>*</tt>, to select all methods with that name.</p> |
||||
<pre> |
||||
preserve = new WildCard { value = "org.myorg.ApplicationClass.main.*" }, |
||||
new WildCard { value = "org.myorg.AppletClass.<init>.()V" }, |
||||
new WildCard { value = "org.resources.Bundle*.<init>.()V" }, |
||||
</pre> |
||||
|
||||
<p>If you want to obfuscate (or just shorten) the identifier you can |
||||
specify a renamer. There are currently following renamer |
||||
available</p> |
||||
<dl><dt>StrongRenamer</dt> |
||||
<dd>Renames to the shortest possible name. You can give a charset |
||||
that should be used. It uses the same name as much as possible.</dd> |
||||
<dt>UniqueRenamer</dt> |
||||
<dd>Renames to unique identifier of the form <tt>xxx123</tt>. Useful |
||||
to reduce name conflicts, before you decompile an obfuscated package.</dd> |
||||
<dt>NameSwapper</dt> |
||||
<dd>This renamer just swaps the names. This is a funny obfuscation |
||||
option that is not very strong, but very confusing.</dd> |
||||
<dt>KeywordRenamer</dt> |
||||
<dd>Renames identifiers to keyword. You can give your own list of |
||||
keywords as parameters. Resulting code is not decompilable directly, |
||||
<b>but it is <i>not</i> legal bytecode either</b>. Some paranoid |
||||
web browsers refuse to run applets containing keywords as identifiers |
||||
(and they are completely within the Java VM spec).</dd> |
||||
</dl> |
||||
<pre> |
||||
renamer = new StrongRenamer |
||||
</pre> |
||||
|
||||
<p>You can also create a renaming table with the same format as the |
||||
table written by revtable. The entries in the table get precedence |
||||
over renamer. Entries not in the table will get renamed by the |
||||
renamer.<p> |
||||
<pre> |
||||
table = "translat.tbl" |
||||
</pre> |
||||
|
||||
<p>Now you can select the analyzer. The purpose of the |
||||
analyzer is to mark all reachable methods, find out which methods |
||||
needs to get the same name (overloading), and which method names |
||||
mustn't change (overload of library methods, e.g. <tt>nextElement</tt> |
||||
for <tt>Enumeration</tt>s). There are currently two analyzers. |
||||
<dl><dt>SimpleAnalyzer</dt> |
||||
<dd>Straight forward analyzer. It is fast and will remove dead code |
||||
on method basis.</dd> |
||||
|
||||
<dd><dt>ConstantAnalyzer</dt> |
||||
<dd>Strong analyzer that will determine, which fields and instructions |
||||
have constant values. It will remove dead code on instruction basis |
||||
and replace constant instruction with a load of the constant, or |
||||
remove them completely.<br> This analyzer is especially useful to |
||||
revert the flow obfuscation of some other obfuscators.</dd> |
||||
</dl> |
||||
</p> |
||||
<pre> |
||||
analyzer = new ConstantAnalyzer |
||||
</pre> |
||||
|
||||
<p>Pre- and Post transformers transform the bytecode before |
||||
resp. after the Analyzer runs. Using this default should be okay. |
||||
You may remove the LocalOptimizer, though, if you have problems.</p> |
||||
<p>In the future I may add some new post transformers, that do string |
||||
encryption, flow obfuscation and similar things. If you want to write |
||||
your own Transformers please contact me, since the next version will |
||||
change the bytecode interface.</p> |
||||
<pre> |
||||
post = new LocalOptimizer, new RemovePopAnalyzer |
