Enterprise-grade Lua obfuscator with a custom register-based VM, 5-layer encryption, and randomized opcode architecture.
Every layer is designed to make reverse engineering as expensive and painful as possible
S-Box substitution, Affine cipher, 12-round Feistel network, Avalanche mixing, key-dependent permutation. All without XOR.
38 opcodes randomly shuffled per build. Instruction fields reordered. Every output has a unique virtual machine that no tool can parse.
Debug detection, environment integrity checks, timing analysis protection, and hash validation. Tampering crashes the script instantly.
100-200 blocks of deeply nested mathematical expressions injected as dead code. Output grows to 100KB+ of pure confusion.
All identifiers become mixtures of l, I, 1, and i. Visually identical characters that are impossible to distinguish manually.
Every string passes through S-box substitution, LCG cipher, and Affine transform. Zero readable text in the final output.
Complete upvalue boxing, recursive functions, callbacks, higher-order functions, closures sharing mutable state. Everything works.
Generate unique raw URLs for every obfuscation. Works with game:HttpGet() in all Roblox executors. Never repeats.
Drop your Lua script or paste code directly. Supports files up to 1MB with any encoding.
Your code is compiled to bytecode, encrypted through 5 layers, wrapped in a custom VM, and flooded with arithmetic noise.
Download the protected file or copy the raw link. Use loadstring(game:HttpGet(url))() in any executor.

Under the hood
The original source code is permanently destroyed during bytecode compilation. Variable names, comments, formatting, and structure are irreversibly lost. What remains is encrypted bytecode running on a unique VM. Source recovery is impossible.
Yes. OVSLTKS is built for Lua 5.1 and Roblox. It works with Synapse X, Solara, KRNL, Fluxus, Script-Ware, and all other major executors. The raw link format is designed for game:HttpGet() compatibility.
By design. 100-200 blocks of complex arithmetic expressions are injected as dead code, expanding the output to 100KB+. This makes automated analysis extremely expensive and manual reading practically impossible.
5 independent layers: S-Box byte substitution, Affine modular cipher, 12-round Feistel network, Avalanche byte mixing, and key-dependent permutation. Each uses random keys generated per build. No XOR.
Initial load takes slightly longer due to decryption. Once loaded, the VM interprets standard Lua bytecode at normal speed. The arithmetic noise only executes during setup.
Yes. Every obfuscation generates different encryption keys, opcode mappings, variable names, and noise patterns. Obfuscating the same file twice produces completely different outputs.
Fully. The VM handles upvalue boxing, recursive functions, callbacks, table.sort comparators, higher-order functions, and closures sharing mutable state. All patterns work correctly.
They see a blocked page. Raw links only serve content to legitimate requests (executors, scripts). Browser navigation is detected and blocked automatically.
