Frequently asked questions

Questions about the Opaquer article catalogue and where to find specific information.

Where can I find all Opaquer .NET Obfuscator technical articles?
All Opaquer technical articles and landing pages are published on opaquer.net. This catalogue page on rustemsoft.com indexes all of them in one place, grouped by topic: obfuscation fundamentals, .NET version support, specific protection techniques (string encryption, control flow, WPF BAML, code virtualization), workflow guides, and the full technical manual. External articles on dev.to, Medium, and LinkedIn are also listed.
Which article should I read first if I'm new to .NET obfuscation?
Start with ".NET Source Code Protection Today" for the conceptual foundation, then "Understanding the Way Obfuscator Software Works" on dev.to for a deeper technical overview. Once you understand the basics, "Why Developers Choose Opaquer" explains what makes Opaquer specifically the right choice, with real before/after IL screenshots.
Where is the article on CI/CD pipeline integration?
CI/CD integration is covered in the Opaquer full manual at opaquer.net/opaquerdoc.html, under the section "Integrating Opaquer .NET Obfuscation into Your Development and CI/CD Azure Pipeline". It includes a complete Azure Pipelines YAML sample, the full CLI flag reference, Visual Studio post-build event configuration, parallel build settings, and a verification checklist. The CLI required for CI/CD is available in Pro and Enterprise editions.
Is there a dedicated article on WPF obfuscation?
Yes. "Best Obfuscator for WPF .NET 10 Applications" is a dedicated technical page explaining why WPF obfuscation fails in most tools (BAML rewriting mismatches causing blank UI and binding failures) and how Opaquer solves the problem by cryptographically encrypting the entire .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.
Where can I read about code virtualization in Opaquer?
"How Does .NET Code Virtualization Work?" is the dedicated article. The Opaquer manual at opaquer.net/opaquerdoc.html also has an extensive "High-Intensity Control Flow Algorithm" section covering the full Enterprise setup process, Certificate IV configuration, Skater.Cloud.Vault NuGet dependency, caching strategy, offline fallback behaviour, and a pre-obfuscation checklist.
Which article explains the Private Keys Depot?
The Opaquer manual at opaquer.net/opaquerdoc.html has a dedicated "Private Keys Depot" section with the full 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.
How do I find which Opaquer edition is right for me?
The edition comparison article gives a full feature-by-feature table. In brief: Basic (free) covers all obfuscation algorithms for solo developers working with the GUI. Pro ($189.99 lifetime) adds the command-line interface for CI/CD automation and the Private Keys Depot. Enterprise ($489.99 lifetime) adds team deployment, offline build server support, high-intensity control flow, and cloud code virtualization. The article "Free .NET Obfuscator" explains in plain terms what Basic includes and what it doesn't.
Are there articles on how to protect only sensitive parts of an assembly?
Yes. "Search & Protect Sensitive Code" is dedicated to this topic. It explains Opaquer's built-in keyword search, a six-step targeted obfuscation workflow, nine categories of code that typically need the strongest protection (encryption, licensing, authentication, proprietary algorithms, etc.) with recommended search keywords for each, and a comparison of targeted versus blanket obfuscation approaches. The article "Why Developers Choose Opaquer" also covers this in its "Real Protection, Explained Clearly" section.
