LLObf: Code Obfuscation & Encryption (IL2CPP & Mono)
Protect Mono and IL2CPP Unity builds with build-time obfuscation, string encryption, IL2CPP metadata encryption, and runtime integrity tools.

Protect the code behind your Unity release.
LLObf is a build-time security toolkit for Unity projects using Mono or IL2CPP. It helps reduce the amount of readable code, exposed strings, predictable logic, and vulnerable client-side data inside your shipped player.
Import LLObf, configure the protection layers you need, and build through your normal Unity workflow.
WHY LLObf?
A successful build is not necessarily a protected build.
LLObf adds multiple practical protection layers to your release process:
- Make managed code harder to read and analyze.
- Hide sensitive strings such as URLs, configuration values, and service identifiers.
- Disrupt predictable control flow and static analysis.
- Protect selected runtime values from casual memory editing.
- Add IL2CPP metadata protection for supported builds.
- Add optional native integrity and anti-cheat checks on Windows Standalone.
