Start here if you're new to .NET obfuscation, evaluating Opaquer, or comparing editions. These articles answer the core questions before you install anything.
Why .NET code protection is essential in an era of prevalent cyber threats, and how obfuscation protects intellectual property, prevents code replication, and boosts application security.
An all-inclusive overview of Opaquer: why it was built to replace Skater .NET Obfuscator, how it stops reverse engineering, protects code without source changes, and integrates into CI/CD via CLI.
Four reasons developers trust Opaquer: transparent protection with real before/after IL screenshots, CI/CD automation, visible upfront pricing with no sales wall, and a genuinely free trial.
Direct answer, before/after IL screenshots, competitor comparison table, pricing, and FAQ - everything you need to decide whether Opaquer is the right tool for your modern .NET project.
What Opaquer Basic includes free (name obfuscation, string encryption, control flow, WPF BAML, watermarking) and the three operational features that require a paid upgrade. No time limit.
Full feature-by-feature comparison of all three Opaquer editions with pricing. Basic is free forever. Pro adds the CLI at $189.99 lifetime. Enterprise adds team deployment and code virtualization at $489.99 lifetime.
Articles covering which .NET versions Opaquer supports and the specific considerations for each.
How Opaquer works with .NET 10 framework-dependent deployments, the runtime requirements on the build machine, and what is needed to protect modern .NET 10 assemblies including DLLs and EXEs.
Opaquer's broad framework compatibility - from .NET Framework 1.0 through 4.8, .NET Core, and all modern versions through .NET 10. How to protect assemblies from both legacy and current runtimes in one tool.
Technical articles on each of Opaquer's protection algorithms: what they do, how they work, and when to use them.
How Opaquer encrypts every string literal - API keys, SQL queries, connection strings - at build time using AES-256, 3DES, or SHA-256. Includes the separate native DLL option for maximum security.
Why automated deobfuscation tools like de4dot cannot reverse Opaquer's protection. Covers randomized instruction set architectures, the absence of static signatures, and pattern-based unpacker resistance.
Enterprise-only deep dive. How critical method fragments are extracted, encrypted, uploaded to Skater Cloud Vault, and executed inside a secure VM at runtime - completely invisible to static analysis and decompilers.
WPF obfuscation is fundamentally different from console app protection. These articles explain why classical obfuscators break WPF applications - and how Opaquer avoids the problem entirely.
How to integrate Opaquer into your development process - from finding sensitive code to automating every build.
The definitive reference documents for Opaquer: the full technical manual, CLI reference, Private Keys Depot API, and assembly settings guide.
Technical articles and guides published by Rustemsoft on dev.to, Medium, LinkedIn, and other sites.
Step-by-step tutorial on applying Opaquer to a full .NET assembly - from opening in the GUI to verifying results in ILSpy. Practical walkthrough for first-time users.
Conceptual guide to how .NET obfuscation software works under the hood - name mangling, control flow transformation, string encryption - written for developers new to the topic.
Full user manual for the Private Keys Depot cloud key management system. Covers account setup, Certificate IV, the KeysDepot class API, key CRUD operations, and cryptographic algorithm selection.
Why Rustemsoft developed Opaquer to replace Skater .NET Obfuscator, what capabilities were added for modern .NET, and how the two tools compare.
Technical background on how WPF compiles XAML to BAML and embeds it in the .g.resources section of the assembly - foundational knowledge for understanding WPF obfuscation.
Questions about the Opaquer article catalogue and where to find specific information.
.g.resources BAML section. It includes a competitor comparison table, before/after screenshots, the ILSpy System.NotSupportedException confirmation, and a full FAQ. The Opaquer manual also has a dedicated XAML/BAML section with WPF screenshots.KeysDepot class API reference, DepotKey and Certificate data structure documentation, a worked C# example replacing a SQL connection string with a depot-retrieved key, and links to GitHub repositories for .NET Framework 4.8 and .NET 10 integration examples. The Medium article is the standalone user manual for the service itself.Download the free Basic edition, open your assembly, and see what Opaquer does to it in ILSpy. No time limit.
