Xamarin weakening

Question

Is there anything that does obfuscation? I tried Crypto Obfuscator for Android, and when I decompiled using dex2jar, I do not see the difference between obfuscation and normal build. So far I have been looking at the following links:

Mono for Android, code obfuscation

Thanks Jay

Answer 1

You are referring to a forum post on xamarin.com ("Light Obfuscation"). There, now I added an explanation of how to mess with Xamarin Studio and Babel for .NET.

I will repeat it here:

Visual Studio, . Babel .NET Xamarin Studio ( Windows). Mac, , .

, , Android Xamarin Studio:

, Xamarin Studio MSBuild, Babel MSBuild.

( Babel) :

( 1)

.csproj . Xamarin Studio .

<Project>

    [... All existing stuff ...]

    <UsingTask TaskName="Babel" AssemblyName="Babel.Build, Version=6.4.0.0, Culture=neutral, PublicKeyToken=138d17b5bd621ab7" />
    <Target Name="AfterBuild" Condition=" '$(Configuration)' != 'Debug' ">
    <Babel InputFile="$(TargetPath)" OutputFile="$(TargetPath)" GenerateDebug="true" 
    [...]
    RulesFiles="babel.xml" 
    SuppressIldasm="false" ObfuscateTypes="true" ObfuscateProperties="true" ObfuscateEvents="true"      ObfuscateMethods="true" 
    ObfuscateFields="true" VirtualFunctions="true" FlattenNamespaces="false" 
    StringEncryption="true"
    />
    </Target>

</Project>
