<h2>Main</h2>
|
|
|
|
<p class="intro">
|
|
<b>ProGuard</b> is a free Java class file shrinker, optimizer, obfuscator, and
|
|
preverifier. It detects and removes unused classes, fields, methods, and
|
|
attributes. It optimizes bytecode and removes unused instructions. It renames
|
|
the remaining classes, fields, and methods using short meaningless names.
|
|
Finally, it preverifies the processed code for Java 6 or higher, or for Java
|
|
Micro Edition.
|
|
</p>
|
|
Some uses of <b>ProGuard</b> are:
|
|
<ul>
|
|
|
|
<li>Creating more compact code, for smaller code archives, faster transfer
|
|
across networks, faster loading, and smaller memory footprints.</li>
|
|
|
|
<li>Making programs and libraries harder to reverse-engineer.</li>
|
|
|
|
<li>Listing dead code, so it can be removed from the source code.</li>
|
|
|
|
<li>Retargeting and preverifying existing class files for Java 6 or higher, to
|
|
take full advantage of their faster class loading.</li>
|
|
|
|
</ul>
|
|
<p>
|
|
<b>ProGuard</b>'s main advantage compared to other Java obfuscators is
|
|
probably its compact template-based configuration. A few intuitive command
|
|
line options or a simple configuration file are usually sufficient.
|
|
The user manual explains all available options and shows examples of this
|
|
powerful configuration style.
|
|
<p>
|
|
<b>ProGuard</b> is fast. It only takes seconds to process programs and
|
|
libraries of several megabytes. The results section presents actual figures
|
|
for a number of applications.
|
|
<p>
|
|
<b>ProGuard</b> is a command-line tool with an optional graphical user
|
|
interface. It also comes with plugins for Ant, for Gradle, and for the JME
|
|
Wireless Toolkit.

|
<b>ProGuard</b> now has a sibling optimizer and obfuscator for Android:
|
|
<a href="http://www.saikoa.com/dexguard" target="_top"><b>DexGuard</b></a>. It
|
|
focuses on code protection, with additional features like string encryption,
|
|
class encryption, and dex splitting. It directly targets Dalvik bytecode and
|
|
streamlines the Android build process.
