As some people do not know how to do this, and it is useful to prevent people stealing your code, here is how to obfuscate (https://en.wikipedia.org/wiki/Obfuscation) using ProGuard.

 

If you don't know what Obfuscation looks like, here is an example of one of my classes, post obfuscation:

 

import java.util.Arrays;
import java.util.Iterator;
import java.util.List;
import java.util.function.Function;
import java.util.stream.Collector;
import java.util.stream.Collectors;
import java.util.stream.Stream;
import org.osbot.rs07.api.Bank;
import org.osbot.rs07.api.Inventory;
import org.osbot.rs07.api.filter.Filter;
import org.osbot.rs07.api.model.Item;
import org.osbot.rs07.utility.ConditionalSleep;

public final class a
extends g {
    private final List b;
    private final ConditionalSleep c;

    public a(Combiner combiner, List list) {
        super(combiner);
        this.c = new b(this, 5000);
        this.b = list;
    }

    @Override
    public final boolean a() {
        for (c c2 : this.b) {
            if (!c2.d()) continue;
            return false;
        }
        return true;
    }

    @Override
    public final void b() {
        if (this.a.getBank() != null) {
            if (!this.a.getBank().isOpen()) {
                a a2 = this;
                try {
                    a2.a.getBank().open();
                    a2.c.sleep();
                }
                catch (InterruptedException var4_3) {
                    a2.a.log((Object)var4_3);
                    return;
                }
            }
            Object object = this.b.iterator();
            while (object.hasNext()) {
                a a3;
                f[] arrf;
                f[] arrf2;
                boolean bl;
                block12 : {
                    boolean bl2;
                    block11 : {
                        arrf2 = arrf = (f[])object.next();
                        a3 = this;
                        for (f f2 : arrf2.c()) {
                            if (a3.a.getBank().contains(new String[]{f2.a})) continue;
                            bl2 = false;
                            break block11;
                        }
                        bl2 = true;
                    }
                    if (!bl2) continue;
                    arrf2 = arrf;
                    a3 = this;
                    arrf = arrf2;
                    object = a3;
                    arrf = a.a((c)arrf);
                    Filter[] arrfilter = new Filter[1];
                    arrfilter[0] = arg_0 -> a.b((List)arrf, arg_0);
                    if (object.a.getInventory().contains(arrfilter)) {
                        arrf = arrf2;
                        object = a3;
                        arrf = a.a((c)arrf);
                        Filter[] arrfilter2 = new Filter[1];
                        arrfilter2[0] = arg_0 -> a.a((List)arrf, arg_0);
                        object.a.getBank().depositAllExcept(arrfilter2);
                        return;
                    }
                    arrf = arrf2;
                    object = a3;
                    for (f f2 : arrf.c()) {
                        if (object.a.getInventory().getAmount(new String[]{f2.a}) <= (long)f2.b) continue;
                        bl = true;
                        break block12;
                    }
                    bl = false;
                }
                if (bl) {
                    arrf = arrf2;
                    object = a3;
                    for (f f2 : arrf.c()) {
                        if (object.a.getInventory().getAmount(new String[]{f2.a}) <= (long)f2.b) continue;
                        object.a.getBank().deposit(f2.a, (int)object.a.getInventory().getAmount(new String[]{f2.a}) - f2.b);
                    }
                    return;
                }
                for (f f2 : arrf2.c()) {
                    if (a3.a.getInventory().contains(new String[]{f2.a})) continue;
                    a3.a.getBank().withdraw(f2.a, f2.b);
                }
                return;
            }
            this.a.log("Ran out of ingredients, stopping script.");
            this.a.stop(true);
        }
    }

    private static List a(c c2) {
        return Arrays.stream(c2.c()).map(f2 -> f2.a).collect(Collectors.toList());
    }

    private static /* synthetic */ boolean a(List list, Item item) {
        return list.contains(item.getName());
    }

    private static /* synthetic */ boolean b(List list, Item item) {
        if (!list.contains(item.getName())) {
            return true;
        }
        return false;
    }
} 

 

1. Download and extract proguard http://sourceforge.net/projects/proguard/files/

 

2. Create a folder anywhere called "proguard_configs", this is where you will store your configuration files to be used with ProGuard.

 

3. In the proguard_configs folder, create a new empty proguard config file (.pro) in notepad.

 

4. Define your configuration, here is the configuration I use for my scripts:

-injars       C:\Users\Username\OSBot\Scripts\script.jar 
-outjars      C:\Users\Username\Obfuscated\script_obf.jar 
-libraryjars  C:\Users\USername\Downloads\OSBot 2.4.29.jar 
-libraryjars  C:\Program Files\Java\jre1.8.0_66\lib\rt.jar

-keepattributes *Annotation*

-keep public class package.Main

  • -injars is file path to the script .jar to be obfuscated

  • -outjars is the file path to the obfuscated script .jar

  • -libraryjars are the OSBot.jar and the Java runtime rt.jar

  • -keepattributes *Annotation* ensures that we keep the @ScriptManifest annotation

  • Finally we specifiy that we want to keep the main Script class, as we need this as the entry point to our script.

  • You should replace "package.Main" with the package that your script is in, and the name of your main script file

 

5. Finally run the following command in cmd / terminal, replacing path_to_proguard with the path to proguard.jar, which is found in the proguard\lib folder, and path_to_config with the path to the .pro file you previously made:

java -jar path_to_proguard.jar @path_to_config.pro

6. Note if you get warnings about missing classes, that are not classes you have defined, add to you config the line, replacing javafx with the package name:

-dontwarn javafx.**
