rymga Lock Master
Make reverse-engineering not worth it. The next-generation Java bytecode obfuscator.
To pull your code apart, an attacker has two ways in: study it standing still, or watch it run. rymga Lock Master closes both. Your classes ship sealed, your logic is scrambled past reconstruction, every string is encrypted to the code that uses it, and the whole build turns hostile the moment someone attaches a debugger. What follows is the entire engine, part by part.
Encrypted at rest
Flow obfuscation
Asset & string encryption
Runtime protection
Traceability & stability

Make reverse-engineering not worth it. The next-generation Java bytecode obfuscator.
To pull your code apart, an attacker has two ways in: study it standing still, or watch it run. rymga Lock Master closes both. Your classes ship sealed, your logic is scrambled past reconstruction, every string is encrypted to the code that uses it, and the whole build turns hostile the moment someone attaches a debugger. What follows is the entire engine, part by part.
Encrypted at rest
- ClassGuard: classes are encrypted, stripped from the archive, and unsealed only in memory at load time.
- Modern runtime support: custom bootstrap loader unseals classes cleanly even on today's reflection-hardened runtimes.
Flow obfuscation
- Graph rebuilding: control flow is flattened, re-routed, and padded with opaque predicates and dead-but-live code.
- Traps & computations: fake loop back-edges, overlapped exception ranges, and constants replaced by mixed boolean-arithmetic.
- Caller-bound branches: branch viability depends entirely on values passed from the call site.
Asset & string encryption
- Unique string keys: every string is encrypted individually with keys derived from the calling class.
- Opaque references: method calls and field access are rewired with placeholders.
- External storage: option to move all encrypted strings into a single sealed file off the class files.
Runtime protection
- Anti-debug: inspects JVM launch configs; classes never unseal if debuggers or agents are attached.
- Anti-dump: live memory dumping is neutralized since class keys only resolve in a clean process.
Traceability & stability
- Redundant watermarking: keyed, fragmented license identifiers survive re-jarring and trace leaks back to the source.
- Offline verifier: checks every class against JVM rules before delivery to guarantee zero crashes.
- Concurrency-aware: hardens timing-sensitive code safely to prevent race conditions.
- Deterministic builds: supports incremental name mapping to keep public APIs stable across updates.
