Class ObfuscateTask

This is an MSBuild task to automate obfuscation using ArmDot.

Read more about how to use ObfuscateTask to obfuscate assemblies while building a project.

Inheritance

System.Object

ObfuscateTask

Implements

ArmDot.Engine.Builder.IAsyncOperationEvents

Namespace: ArmDot.Engine.MSBuildTasks

Assembly: ArmDot.Engine.MSBuildTasks.dll

Syntax

public class ObfuscateTask : Build.Utilities.Task, IAsyncOperationEvents

Properties

EmbeddedFiles

This parameter is optional.

Inputs stores a list of files to embed.

Notes: use %24 to encode $

For example, use %24(AssemblyDirectory) to encode $(AssemblyDirectory)

<ItemGroup>
  <FilesInfo Include="$(TargetDir)Embed\virtual_file_content2.txt">
    <RuntimePath>%24(AssemblyDirectory)\embedded_file2.txt</RuntimePath>
  </FilesInfo>
  <FilesInfo Include="$(TargetDir)Embed\virtual_file_content3.txt">
    <RuntimePath>%24(AssemblyDirectory)\embedded_file3.txt</RuntimePath>
  </FilesInfo>
</ItemGroup>

<Target Name="Protect" AfterTargets="Build">
  <ItemGroup>
     <Assemblies Include="$(TargetDir)$(TargetFileName)" />
  </ItemGroup>
  <ArmDot.Engine.MSBuildTasks.ObfuscateTask
    Inputs="@(Assemblies)"
    EmbeddedFiles="@(FilesInfo)"
    ReferencePaths="@(_ResolveAssemblyReferenceResolvedFiles->'%(RootDir)%(Directory)')"
  />
</Target>

Declaration

public ITaskItem[] EmbeddedFiles { get; set; }

Property Value

Type	Description
ITaskItem[]

Inputs

This parameter is required.

Inputs stores a list of assemblies to protect:

<Target Name="Protect" AfterTargets="Build">
  <ItemGroup>
     <Assemblies Include="$(TargetDir)$(TargetFileName)" />
  </ItemGroup>
  <ArmDot.Engine.MSBuildTasks.ObfuscateTask
     Inputs="@(Assemblies)"
     ReferencePaths="@(_ResolveAssemblyReferenceResolvedFiles->'%(RootDir)%(Directory)')"
  />
</Target>

Also, Inputs can contain options for an assembly.

The following options are available:

KeyFile specifies the path to the file containing the key pair, which is used to generate a strong name. If specified, ArmDot signs the assembly after obfuscation using the specified file. Use this option if an assembly is a strong-named one. Obfuscation modifies an assembly making a strong name signature not valid. That is why signing is required:

<Target Name="Protect" AfterTargets="Build">
  <ItemGroup>
     <Assemblies
       Include="$(TargetDir)$(TargetFileName)"
       KeyFile="key.snk"
     />
  </ItemGroup>
  <ArmDot.Engine.MSBuildTasks.ObfuscateTask
     Inputs="@(Assemblies)"
     ReferencePaths="@(_ResolveAssemblyReferenceResolvedFiles->'%(RootDir)%(Directory)')"
  />
</Target>

Declaration

public ITaskItem[] Inputs { get; set; }

Property Value

Type	Description
ITaskItem[]

License

This parameter is optional.

Set it to a purchased ArmDot license key.

If License is not set, ArmDot works in the demo mode.

Declaration

public string License { get; set; }

Property Value

Type	Description
System.String

NoWarn

This parameter is optional.

Suppresses the ArmDot's ability to generate warnings.

NoWarn specifies warning number or numbers.

If you specify multiple warning numbers, separate them with a comma:

<Target Name="Protect" AfterTargets="Build">
  <ItemGroup>
     <Assemblies Include="$(TargetDir)$(TargetFileName)" />
  </ItemGroup>
  <ArmDot.Engine.MSBuildTasks.ObfuscateTask
    Inputs="@(Assemblies)"
    NoWarn="4"
    ReferencePaths="@(_ResolveAssemblyReferenceResolvedFiles->'%(RootDir)%(Directory)')"
  />
</Target>

Declaration

public string NoWarn { get; set; }

Property Value

Type	Description
System.String

ProjectPath

This parameter is optional.

ProjectPath specifies a path to a project file that is used to store cryptography constants to generate license keys, and blacklisted license keys.

If ProjectPath doesn't exist, a new project file is created.

Declaration

public string ProjectPath { get; set; }

Property Value

Type	Description
System.String

ReferencePaths

This parameter is optional.

ReferencePaths stores a list of directories to find referenced assemblies.

Sometimes ArmDot needs to find an assembly referenced by the assembly which is being protected.

To help ArmDot locate such an assembly, use ReferencePaths:

<Target Name="Protect" AfterTargets="Build">
  <ItemGroup>
     <Assemblies Include="$(TargetDir)$(TargetFileName)" />
  </ItemGroup>
  <ItemGroup>
    <ReferencePaths Include="C:\MyAssemblies" />
    <ReferencePaths Include="@(_ResolveAssemblyReferenceResolvedFiles->'%(RootDir)%(Directory)')" />
  </ItemGroup>
  <ArmDot.Engine.MSBuildTasks.ObfuscateTask
    Inputs="@(Assemblies)"
    ReferencePaths="@(ReferencePaths)"
  />
</Target>

Declaration

public ITaskItem[] ReferencePaths { get; set; }

Property Value

Type	Description
ITaskItem[]
