A Cross-Platform .NET Obfuscator for C# and VB.NET

ArmDot is a .NET obfuscator to protect software written in .NET.

Using the full arsenal of obfuscation techniques, starting with common, but very effective renaming of metadata: names of classes, methods, and properties, and ending with the most modern approach – code virtualization, which makes deobfuscation incredibly difficult.

Licensing API

ArmDot provides a rich API to generate license keys, check their state, and extract data stored in license keys, including user name, email, expiration, and max build date.

What does ArmDot offer?

  • Virtual Machine that makes code completely incomprehensible. The goal is to convert the original code into an illegible form. ArmDot has a proven approach that is widely used for the unmanaged code: the original code is converted into an array of bytes that is interpreted by special virtual machine. Each time you apply ArmDot, it creates a new version of virtual machine and uses a new set of instructions to represent the original code.
  • Mix Code is a technique that makes extracting license code checking very complicated. The license key checking code is mixed with the original code and it’s really hard to separate one code from another one cause both use the same variables and their instructions overlap.

Embed files with the help of ArmDot

It’s easy to add dependencies: managed and unmanaged DLLs, data files and other assets to the output .NET assembly.

If a .NET code requires an unmanaged DLL, just add the DLL to Assembly Directory and build the project.

After building the project, the output .NET assembly will function as if the embedded DLL were actually present.

In other cases, one may need to hide assets: videos, images, and other files. Embedded files are not stored on a disk, but in the process memory instead; it’s hard to extract them.
