JavaObfuscator

Java obfuscator with Minecraft plugins supports. Based on ColonialObfuscator

⚠️ NOTE: It’s quite stable on Java 7–25 and works very well with Minecraft Paper plugins. I’m unlikely to actively maintain it further.

Features

• String Encryption - Encrypts string constants with XOR-based encryption
• Number Obfuscation - Obfuscates integer, long, float, and double constants
• Boolean Obfuscation - Transforms boolean values with complex expressions
• Flow Obfuscation - Creates complex control flow patterns
• Dispatcher - Converts methods to use dispatcher pattern
• Shuffle - Randomizes order of fields and methods

Obfuscation

Before:

         public boolean returnTrue() {
             return true;
         }

         public boolean returnFalse() {
             return false;
         }

         public void testConditions(int n, int n2, int n3) {
             if (n == 200) {
                 System.out.println("n is 200");
             }
             if (n2 == 500) {
                 System.out.println("test2 is 500");
             }
             if (n3 != -1) {
                 System.out.println("n2 is not -1");
             }
         }
     }

After:

public class Test {
         static char[] кГБфбдГТЕжкД_ЭнЮгЧЙйАнЗроорцПРяЖФИНшйюЮмкЯУмЇиЙГИЖтЪА;

                 new Object[]{n, n2, n3}
             );
         }

                 System.out.println(ЯУШЇюЙдыгЛшТпхеДчфЬкХйЕцюЩПкРБчГЖСэнІВжЙ(...));
             }
             if (n2 == (0x56F338AE ^ кГБфбдГТЕжкД_ещмСРУУалнГлВпоЫЬЭОХХоиуЫмєЇпкУцДоСзЕвСц(

                 System.out.println(ЯУШЇюЙдыгЛшТпхеДчфЬкХйЕцюЩПкРБчГЖСэнІВжЙ(...));
             }
             if (n3 != (0xC0A86905 ^ кГБфбдГТЕжкД_ещмСРУУалнГлВпоЫЬЭОХХоиуЫмєЇпкУцДоСзЕвСц(...))) {
                 System.out.println(ЯУШЇюЙдыгЛшТпхеДчфЬкХйЕцюЩПкРБчГЖСэнІВжЙ(...));
             }
         }

         public boolean returnTrue() {
             return (Boolean)this.кГБфбдГТЕжкД_жЖЮШАкляіЙвВїиЩьЬюМШЧеФекаьхУтВмвщЩщювЫШ(
                 0x289DDE0C ^ 0x289D9FD7, new Object[0]
             );
         }

         public boolean returnFalse() {
             return (Boolean)this.кГБфбдГТЕжкД_жЖЮШАкляіЙвВїиЩьЬюМШЧеФекаьхУтВмвщЩщювЫШ(
                 0x3631CF9A ^ 0x3631D9A5, new Object[0]

         }
     }
