I obtain the same crproj file whatever the settings I configured using the GUI for ConfuserEx v0.2.1. I would expect the crproj file to include configured settings so that I can save it and replay it.

I tried the ConfuserEx to obfuscate my main dll and it turns out almost everything is working except one screen that does not shows up. I decided to use the None preset setting and it still didn't worked. So I used Reflector to decompile both dll (original and obfuscated) and exported the source code. Then I diff both code and I realized that ConfuserEx was modifying a local byte array even in None mode... The attachment shows the behaviour (the left is the obfucated version).

its always been crashing once i creating

can you .cli example to use resource and .snk

Hey Ki (and team!)

I'll start off by saying, I'm pleased someone has picked up Confuser, and very impressed so far with the work you guys have done. Keep it up!

I've noticed an issue with the most recent build (0.2.1), whereby if you add a 'probe path' to the advanced settings, and then attempt to save the project, it crashes the app.

Let me know if you need any further info.

Thanks

This isn't an issue as much as a request/idea for a feature. Would it be difficult to add the ability to exclude private fields marked with the [System.Serializable] attribute? There are cases where the names of these variables are important to preserve.

Using ConfuserEx for some of my dll's, I've noticed that while the app runs well on my windows 7/server machines, it fails to run on various Windows 8.1 machines.

The raised exception is appears scrambled.
Anyone else experienced this issue?

To see the error (if you're running Windows 8) - try installing this: http://www.doccolabs.com/download/download_sqltablezip.html

Name Protection, set to renameArgs = true renames all public method arguments even when renPublic = false. Also, public arguments should probably not be renamed by default.

hi sir
error on compile
Error 9 Missing compiler required member 'System.Runtime.CompilerServices.ExtensionAttribute..ctor' J:\ConfuserEx\ConfuserEx\Confuser.Core\CSC Confuser.Core

once i protect a exe with max label in windows 7 or 8 my exe got crashes . but if i run that exe in xp , the exe run fine.

Build Fail (update version: invalid argument length.) if have space in source directory name

Hi,

Awesome tool, but one missing piece I would love to have to round it out is a stack trace decoder. Any plans to add that any time soon?

Thanks

hi,
As I had a lot of trouble writing mine from the start pre-EX version.
I will detail how I converted to the new .crproj EX format to help you.
This was a very simple config file.

1. In the 'additional' folder of the source code are example .crproj files for EX
   This helps a lot to get the basic structure correct.
2. the preset attribute has been moved to the next level below <project.
   e.g.,
   <proj...
   

The pattern attribute is mandatory so just use the above.

1. <assembly has been changed to <module
   Again next level
   e.g.,
   <proj...
   <module path= the same format

This is my first and very basic conversion, a harder one is to come so will detail that!

Thank you.

I've used confuser. Using Assembly.Load and entrypoint invoke throws a strange error message. Can i disable some plugin over the xml file ? After deleting a line like protection id="anti tamper" it's still use these protection.

Hi. I really need to have pattern function like ispublic() or so for test member or class definition for visibility outside the assembly. thanks

I get everytime a null reference exception in the ConfuserProject.cs at row 470.

Hi,

i love the Confuser, but i noticed that my C# code for retrieving a resource, in this case a byte array is not working anymore.

This only happens if i use the Renamer option. once i disabled it, my program can find the resource again.

I´m using .NET 4.0.
Target machine: x86

and i use the standard generated static classes of .NET to access my resources: Resources.

Do i need to use a different way to retrieve my resource data, or is this a bug?

Ps. i also noticed that if i use the compressor the application fails completely, but i don't really need the compressor. but i want renaming to work!

I have used Confuser (codeplex). It does not seem to support MVVM or I am lacking some knowledge on how to use the tool.

These days, I am trying to use ConfuserEx (v0.2.1) and I am hardly getting anywhere. I tried GUI as well as CLI tool but the output exe is crashing all the time. Tried a dozen crproj xml settings as per the ConfuserEx documentation in /docs/ProjectFormat.md and using /additional/ilspy.crproj but no luck.

Hi,

Please add force rename symbols in renaming for rename all symbols.

Just pulled the code to see if it will work on my current project. Spent about 30 Minutes trying to resolve the build errors. Got the dnlib reference added. The only real build error its showing me now is:

Error 18 The type or namespace name 'ImportResolver' could not be found (are you missing a using directive or an assembly reference?) E:\Git Repository\ConfuserEX\Confuser.Core\Helpers\InjectHelper.cs 235 33 Confuser.Core

Please let me know if there is any more information that i can provide to get this solved. Thanks!

FIrst thanks for the update!
But, well the GUI crashs on Windows 7 x64 with latest .NET Framework.

Exception: http://pastebin.com/raw.php?i=gC2LUerN (means in english, it couldn't load/find an assembly)

Ask me if you need more details.

project baseDir="." outputDir="Confused" xmlns="http://confuser.codeplex.com">

module path="C:\Users\Xenocode\Desktop\cftest.exe" />

the output cant be localized, like nowhere

Running ConfuserEx on my assemblies calls GetAttributeType(null), which throws an UnreachableException.

I don't really know what I could provide to help figure out what is happening.

I am running ConfuserEx from latest source.
Windows8.1, multiple exes and dlls of WPF, C#4.5.
I don't own the code I am obfuscating, so I cannot share the source executables or dlls.

BAMAnalyzer.cs method ResolveAttribute, line 199 gets info=

{(DockPanel, , System.Windows.Controls.Dock)}
    Item1: DockPanel
    Item2: null
    Item3: {System.Windows.Controls.Dock}

Which then returns Tuple.Create<IDnlibDef, TypeDef>(info.Item2, info.Item3); to ProcessElementBody() line 359. Notice that the first param is null!
Then it does

type = attrInfo.Item2;
attr = attrInfo.Item1;
if (elem.Attribute != null)
    type = GetAttributeType(attr);

which sends a null to GetAttributeType(), and that one does throw new UnreachableException();.

Foo.crproj:

<?xml version="1.0" encoding="utf-8"?>
<project  baseDir="D:\code\Foo"
        outputDir="D:\code\Foo\Obfuscated"

    <module path="D:\code\Foo\Foo.Model.dll" />
    <module path="D:\code\Foo\Foo.Shared.dll" />
</project>

I tried using the "antinet" preset with the "anti debug" protection but it seems to cause an exception with ConfuserEx. The exception occurs in the method GetParameter in ProtectionParameters.cs which throws an exception for the key being null.

This is what the project looks like (might be something wrong):

<?xml version="1.0" encoding="utf-8"?>
<project baseDir="." outputDir="Confused" xmlns="http://confuser.codeplex.com">
    <rule preset="none" pattern="true">
        <protection id="anti debug">

        </protection>
        <protection id="anti dump" />
        <protection id="anti ildasm" />
        <protection id="anti tamper">
            <argument name="mode" value="jit" />
        </protection>

        </protection>
        <protection id="ctrl flow" />
        <protection id="invalid metadata" />
        <protection id="ref proxy">
            <argument name="mode" value="strong" />
            <argument name="encoding" value="expression" />
        </protection>
        <protection id="rename">
            <argument name="mode" value="unicode" />
        </protection>
        <protection id="resources" />
    </rule>
    <module path="test.exe" />
</project>

EDIT - Also tried with other presets and it still produces the same issue. My guess it's to do with this line of code in NameService.cs:

analyze.Analyze(this, context, ProtectionParameters.Empty, def, true);

Which eventually leads to GetParameter in ProtectionParameters.cs and throws an exception for the key being null:

// For protections
var objParams = context.Annotations.Get<ProtectionSettings>(target, ParametersKey);
if (objParams == null)
    return defValue;
if (!objParams.TryGetValue(comp, out parameters))
    return defValue;

Making this edit seems to fix the problem:

if (comp == null)
    return defValue;
var objParams = context.Annotations.Get<ProtectionSettings>(target, ParametersKey);
if (objParams == null)
    return defValue;
if (!objParams.TryGetValue(comp, out parameters))
    return defValue;

Hello, I confirmed renaming only work for exe but not dll in ConfuserEx v0.1.2,
Here is my crproj

<?xml version="1.0" encoding="utf-8"?>
<project baseDir=".\bin\Debug" outputDir="Confused" xmlns="http://confuser.codeplex.com">
    <rule preset="none" pattern="true">
        <protection id="rename" />
    </rule>
    <module path="ConsoleApplication1.exe" />
    <module path="ClassLibrary1.dll" />
</project>

Only members in ConsoleApplication1.exe are renamed.
Is it a bug or not supported yet?

The assembly has been merged with ilmerge but doesn't include Microsoft.Practices.EnterpriseLibrary.Common.dll.
In either case, Microsoft.Practices.EnterpriseLibrary.Common.dll exists in the same directory as MyAssembly.exe.

Any ideas?

Thank you.

Hello
I am not sure, if this is the right place to ask questions, but I don't know where to ask elsewhere.
Often assemblies need to be signed (with strong name) - for example when implementing own ProtectedConfigurationProvider for protecting sections in application configs.
How can this be achieved when using this confuscator?
Thanks in advance,
Roger

This is more like a Q&A than an issue report but I don't know where to ask so I post it here. Therefore, I'm sorry about that.
In your FAQ, you mention "a generic deobfuscator for different custom version of ConfuserEx would be virtually impossible to be created."

1. What classes in the source code should I work on in order to make a custom version?
2. Is it helpful if I provide a seed to crproj file?
3. If my application includes a strong name key, does it make harder being deobfuscated?
4. And how do I implement a plug-in?
   Thank you very much.

Can't compile Confuser.Core without this dependency; which DLL does it belong to?

Getting the above error when trying to obfuscate a SharePoint client console application. Created a very simple console app to reproduce the error. Uploaded the sample and project xml file to https://onedrive.live.com/redir?resid=A8314A43FAE2ED81%21202

Just wondering what is causing the referenced Microsoft.SharePoint.Client.dll to be processed. I would expect it to be ignored?
Is there a way to tell ConfuserEx to ignore certain classes?

The output from ConfuserEx is:

It looks like abstract methods are specifically excluded from renaming, but I'm not sure why.

To fix it I just commented out line 21 of VTableAnalyzer.cs:

20:    if (method.IsAbstract) {
21:        //service.SetCanRename(method, false);

And now abstract methods are being properly renamed (and overridden methods in derived types correctly pick up the same name).

I want to exclude all member from (ref proxy) only my method added execute process but following project not work, Also, How can add several method without add new rule tag? Thanks.

Today i was using ConfuserEX for obfuscating "MegaDumper" (pretty famus dotnet dumper)
but when ConfuserEx finished to obfuscate, "confused" directory was empty. I tried to obfuscate MegaDumper many times but confused directory still empty. Is there a bug?
Protection prameters that i used:

I got an error when launched protect. Log below.

Assembly.GetType(...) fails when a name starts with the unicode character \u2028.

For example, the following program obfuscated with only the renamer and a seed = "12" will fail.

internal static class Program
{
    static void Main()
    {
        Do<MyClass1>();
        Do<MyClass2>();
        Do<MyClass3>();
        Do<MyClass4>();
        Do<MyClass5>();
        Do<MyClass6>();
        Do<MyClass7>();
        Do<MyClass8>();
        Do<MyClass9>();
    }

    public static void Do<T>()
    {
        Console.WriteLine("Doing {0}", String.Concat(from c in typeof(T).Name
                                                        select String.Format(@"\u{0:x4}", (int)c)));
        var t = Assembly.GetExecutingAssembly().GetType(typeof(T).FullName);
        if (t == null)
            throw new Exception("Type not found!!");
    }
}

internal sealed class MyClass1 { }
internal sealed class MyClass2 { }
internal sealed class MyClass3 { }
internal sealed class MyClass4 { }
internal sealed class MyClass5 { }
internal sealed class MyClass6 { }
internal sealed class MyClass7 { }
internal sealed class MyClass8 { }
internal sealed class MyClass9 { }

Maybe, you should remove the \u2028 character from the allowed characters for the renaming.

Is there support for external plugins implemented yet? As far as I can see ConfuserEx only looks for protections and packers in Confuser.Protections, Confuser.Renamer and Confuser.DynCipher.

Is this intended or am I missing something?

Hi yck, (long time!)

In the documentation the packer tag is said to be unused but it definitely is not ignored.

gives me a build error as below.

when removed it builds fine.

BTW, I have used ILmerge on two assemblies and then renamed that resulting assembly?

Confuser has worked great for us except that anti-virus software flagging our apps as malware. There have been many tickets open for this on codeplex: #8900, #8899, #8645, and esp. #8899 one where you (@yck1509) mentioned that it will be hard to fix. Has this been taken care of or any way for us to fix it compiling from the source? One way that I can think of is to allow to pass some guids or unique signatures in *.crproj that can be used during obfuscation (sorry if this doesn't make sense; I wish I knew more about obfuscation processes).

Please provide steps on how to run the ConfuserEX, is there any user guide?

var root = writer.MetaData.TablesHeap.TypeDefTable.Add(new RawTypeDefRow(0, 0x7fff7fff, 0, 0x3FFFD, fieldLen, methodLen));

What is "0x3FFFD" ? Since if i try to modd the loop statement it doesnt work anymore (app isnt runnable, i meanà

foreach (var ns in namespaces)
{
if (ns == 0) continue;
var type = writer.MetaData.TablesHeap.TypeDefTable.Add(new RawTypeDefRow(0, 0, ns, 0x6FFFD, fieldLen, methodLen));
writer.MetaData.TablesHeap.NestedClassTable.Add(new RawNestedClassRow(root, type));
var type2 = writer.MetaData.TablesHeap.TypeDefTable.Add(new RawTypeDefRow(0, 0, ns, 0x5FFFD, fieldLen, methodLen));
writer.MetaData.TablesHeap.NestedClassTable.Add(new RawNestedClassRow(root, type2));
}

This project exception error after run and error after click button for OpenFileDialog.

Very happy to see public members rename support added,
Can also add support for ObfuscationAttribute?
Here is the description page:

Rules created for specific modules are saved, however rules created for "Global setting" in the ConfuserEx GUI are never saved.
