Opaquer: .NET Obfuscation Reimagined

Opaquer represents the next generation of .NET obfuscation technology, building upon the legacy of the well-established Skater .NET Obfuscator. It is a comprehensive tool designed to safeguard your .NET assemblies from unauthorized reverse engineering, decompilation, and intellectual property theft.

🔹 Opaquer Free Basic Version

The Free version of Opaquer provides an impressive array of .NET protection mechanisms, making it an ideal choice for individual developers and small projects. It delivers a complete code protection suite without altering the core functionality of your application. Key features include:

Advanced Name Mangling: Offers granular control over the renaming (obfuscation) of methods and variables across all access modifiers — public, private, and internal. Developers can selectively include or exclude specific elements from protection, ensuring flexibility where reflection or external dependencies are a concern.
Robust String Encryption: Protects sensitive literals by encrypting them using a choice of cryptographic algorithms, with the option to customize passwords for added security. This feature allows for precise control: developers can encrypt individual strings, all strings within a selected class, or every string across the entire assembly. For an additional layer of security, encrypted strings can either be embedded within the assembly or extracted into a separate, unmanaged binary DLL that resists recompilation.
Lightweight Control Flow Obfuscation: Applies a sophisticated yet performance-conscious control flow obfuscation to protected methods, making the decompiled code logic unintelligible to humans while preserving original program behavior.

🔸 Opaquer Pro

Designed for power users and automated workflows, Opaquer Pro builds upon the foundation of the Free version by introducing a Command-line Interface (CLI). This empowers developers to integrate Opaquer seamlessly into their post-build processes, enabling automated, routine obfuscation as part of continuous integration and delivery pipelines.

⭐ Opaquer Enterprise

The Enterprise edition is the ultimate solution for development teams and large organizations requiring the full spectrum of Opaquer’s capabilities. It includes all features from the Free and Pro versions, with additional enhancements tailored for team-based and production-scale environments:

Unlimited Team Deployment: Licensed for use across an unlimited number of developer workstations within an organization, facilitating seamless collaboration.
Internet-Free Build Server Support: Specifically designed to operate on dedicated build servers in isolated environments, ensuring that software compilation and obfuscation can proceed without any internet connectivity requirements.
High-Intensity Control Flow: Introduces a more aggressive and complex control flow obfuscation algorithm for maximum protection against advanced reverse engineering attempts, ideal for highly sensitive code sections.
