Java - Decompile (JD-GUI) and Obfuscate (Proguard) Exploration
Part 1. The Simple GUI App
Start with a really simple Java GUI application
Create a JAR - basic editor and command line commands !
No Maven, no Gradle, no Netbeans, no Eclipse, etc so we can explore the commands and see what's going on.
Part 2. Compiling the App / creating a JAR
Part 3. Decompiling the original compiled code (JAR) using JD-GUI
Decompile it and compare using JD-GUI
JD-GUI: https://github.com/java-decompiler/jd...
Part 4. Obfuscating the compiled code (JAR) using Proguard
Obfuscate the compiled code with Proguard
Proguard: http://proguard.sourceforge.net/
Part 5. Decompiling the original JAR and the obfuscated JAR and comparing the results using JD-GUI
Decompile the obfuscate build and compare using JD-GUI
6. Why obfuscate ?
Why bother protecting YOUR hard work ?
Future Topics ???
Barely scratched the surface ? Want me to go deeper ?
Other decompilers ? Other Obfuscaters ?
Loading resources (icons, html help, sounds, graphics, etc) from inside the JAR file ?
Additional classes ?
More complex examples ?
Deeper exploration of the results, the settings, etc ?
Yes ?? Well you know what to do ... Hint: watch the end of the video ! :)
