MEQUON, Wis. - s4story -- Rustemsoft Announces the Release of Opaquer .NET Obfuscator

June 18, 2026

Rustemsoft LLC is pleased to announce the official release of Opaquer .NET Obfuscator, a new generation software protection solution designed specifically for modern .NET applications.

As .NET applications continue to become easier to analyze using advanced decompilers and reverse-engineering tools, software developers face increasing challenges in protecting their intellectual property, proprietary algorithms, licensing systems, and sensitive application data. Opaquer .NET Obfuscator was created to address these challenges by providing a comprehensive set of protection technologies for .NET assemblies.

Opaquer helps developers secure their applications through multiple layers of defense, including identifier renaming, string protection, resource protection, and advanced code transformation techniques that significantly increase the difficulty of reverse engineering. The product is designed to protect both traditional .NET Framework applications and modern .NET applications built with the latest versions of the platform.

One of Opaquer's unique capabilities is its advanced string protection technology. Sensitive string values can be encrypted or moved entirely outside managed assemblies into native machine-code modules, making them inaccessible to traditional .NET decompilers and analysis tools. This approach helps protect licensing information, API endpoints, authentication logic, and other critical application assets.

The release of Opaquer builds upon Rustemsoft's long-standing experience in .NET code protection and software security. For many years, Rustemsoft solutions have helped developers protect commercial applications against unauthorized analysis, modification, and intellectual property theft. Opaquer represents the next step in that evolution, introducing modern protection techniques tailored to today's .NET ecosystem.

"We developed Opaquer to provide software vendors with practical and effective protection against reverse engineering," said the Rustemsoft development team. "Our goal was to create a solution that delivers strong security while remaining straightforward to integrate into existing development and deployment workflows."
