LLObf: Code Obfuscation & Encryption (IL2CPP & Mono)

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.
