Jobfuscate

The Jobfuscate application will allow software developers to obfuscate (protect) their Java class files. Otherwise, without protection, anyone could use a Java decompiler to effectively get back your Java source code!
The Problem: Java class files contain lots of symbolic information from your source code, including all variable names and method names that you used in your source code! This symbolic information allows Java decompilers to very effectively reconstruct your source code with the variable names you used. If you have not used a Java decompiler, get one and try it out and you will be amazed. Without obfuscation protection, you are giving away your source code when you ship Java class files.
The Solution: Remove all symbolic information that can be removed. Jobfuscate allows you to use fully descriptive variable names and method names in your Java code. It then renames your classes, variables and methods to meaningless names. No attempt is made to alter the Java byte code because that is where all other obfuscators cause bugs for you to track down.
Usage: jobfuscate [-options]* class*
-log: redirects stdout/stderr to file
-out: names output jar file (default: java.jar)
-store no compression in jar file
-x: no class/method/field renaming in class
-xc exclude all class renaming
-xm exclude all method renaming
-xf exclude all field renaming
-xc: exclude class renaming by pattern
-xm: exclude method renaming by pattern
-xf: exclude field renaming by pattern
-trial runs in trial mode (for debugging)
-sys: identifies system classes by pattern
-serializable: type = off|relaxed|strict
@ each line in is an option
class main class file, plus other class files
Example:
set classpath=c: est
jobfuscate -x:acme.* -xc -xm:io.*.run myprog.mainSystem requirementsSun's Java Runtime Environment 1.4.2 (or later) installed
Limitations in the unregistered versionJobfuscate is shareware. Please try it for free. In the trial, names will be obfuscated, but will be appended with the original name. This intentially provides no obfuscation protection, but it allows you to see that name that would be used and verify that your classes continue to work after being obfuscated. You must pay for the registered version, which provides full obfuscation protection.
