Features

Only documented features are implemented and functional.

Name Obfuscation

Class Renaming

Classes get short or random names (e.g. a, b, c or xk9m2p). Length configurable (1–32 characters).

Method Renaming

Method names are obfuscated. Not renamed:

• main(String[])
• Constructors (<init>, <clinit>)
• Native methods
• Enum methods (valueOf, values)
• toString(), equals(Object), hashCode() – for JDK compatibility

Override chains are detected; overridden methods get the same new name.

Field Renaming

Field names are obfuscated. Not renamed: serialVersionUID, enum constants.

Data Obfuscation

Number Obfuscation

• int: Math expressions (e.g. 123 → (50*3)-27); decompilers show the expression, not the literal
• long, float, double: XOR

Array Obfuscation

Array dimensions are hidden via XOR (new int[8] → new int[(8 ^ key) ^ key]).

Boolean Obfuscation

true and false are hidden via XOR ((value ^ key) ^ key).

String Obfuscation

• XOR encryption
• Inline decryption at each use site (no central decoder)
• Key per class and per string/field
• Static final String fields: ConstantValue is removed; initialization happens in <clinit> with obfuscated code – API keys and secrets never appear readable in bytecode or to strings-style tools

Debug Info Stripping

Removes file names, line numbers, and local variable names. Decompilers show e.g. var0, var1 instead of meaningful names.

Exclude Patterns

Classes/packages can be excluded from renaming:

• * excludes all classes
• Prefix match (e.g. com.example excludes com.example.*)
• Built-in: java.*, javax.*, Bukkit, Minecraft, etc.

Random Options

• classNamesRandom, methodNamesRandom, fieldNamesRandom – random names per build
• numberKeyRandom, arrayKeyRandom, booleanKeyRandom, stringKeyRandom – random keys per build
