I've did research and still can't figure this out, but I know the problem. The problem is that Eazfuscator isn't installed on other peoples pc, but how would I get them to run it without getting this error, and without them installing eazfuscator? Or should I use another one?

This application has been built with an evaluation version of Eazfuscator.NET, and therefore cannot be distributed. You can install Eazfuscator.NET on this computer to be able to run this application.
Microsoft Build Engine, widely known as MSBuild, is a platform for building applications. It can be used directly to build a project, and runs behind the scenes when you are working inside an IDE, such as Microsoft Visual Studio.
The commands specified in the post-build event section are executed after the build is finished. The picture above shows a post-build event command line that runs Eazfuscator.NET with several parameters when the project configuration is set to Release. The command can be easily tweaked using Eazfuscator.NET command-line interface.
Additional command-line options to be passed to Eazfuscator.NET. The following options cannot be used with this property as they are inferred automatically: --msbuild-project-path, --msbuild-project-configuration, --msbuild-project-platform, --msbuild-solution-path. The option -v [ --compatibility-version ] cannot be specified either; please use EazfuscatorCompatibilityVersion MSBuild property instead
Another thing that discloses information about the functioning of a program is strings. To hide this information, Eazfuscator.NET substitutes the strings in your code with calls of special encryption functions, which render your strings perfectly at runtime, leaving them unreadable to an intruder. Also, these functions make the size of your strings lesser by compressing them.
Eazfuscator.NET supports an advanced technique called control flow obfuscation which replaces the IL code with functionally equivalent, but slightly different instructions. Decompilers often crash on such code, so this may stop an intruder from trying to break into your assembly.
After your assembly is obfuscated with Eazfuscator.NET, it doesn't become a brick of non-debuggable mess. You can always get a line number where an unhandled exception appeared, view a readable stack trace, and even attach the debugger to walk through your obfuscated code.
I have a .Net Framework 4.6.1 project and when I try to use Aspose.Cells library, it throws error:
The assembly Aspose.Cells.dll has been built with an evaluation version of Eazfuscator.NET, which has expired.
Aspose team, please renew obfuscator license for this product
I want to obfuscate my app with Eazfuscator.NET but I also want to publish it with ClickOnce (I use the Install from CD option). But Eazfuscator only let me obfuscate assemblies and I don't know which assembly to obfuscate when my project is published since there are many of them. Perhaps I need to obfuscate it before publishing it but still not sure how would this be done. Hope anyone can help.
Visual Studio integration allows to get an immediate help for any Eazfuscator.NET directive. Just press F1 in the text editor and you will be rewarded with a swath of detailed information.
WARNING Assembly at file path "C:\Users\New folder\ZedGraph.dll" should be signed with a key to work properly after obfuscation. Please use 'key-file' or 'key-container' option.Alternatively, .snk key file can be placed near the input assembly and processed automatically.
I'm trying to obfuscate a .net project with
eazfuscator.net. The problem is that, when I decompile it using .NET Reflector you can see to much of the code. All the private members are obfuscated, but the public members give to much information about the program.
One option is to merge all the dependent assemblies to a single giant assembly(exe), then obfuscate the merged assembly with obfuscate public members option. In that way, you can obfuscate public members at the same time not breaking anything.
Using
eazfuscator.net 3.3.0 I'm having this error: "Common Language Runtime detected an invalid program" This happens when i put the mouse cursor over a datagridview. I'm using C # in visual studio 2010.
Eazfuscator.NET extension for Visual Studio was made with performance in mind. For example, it is activated for obfuscated projects only and never looks at the projects which do not use Eazfuscator.NET. Moreover, it uses only the most efficient data structures, code and algorithms to make your work productive and pleasant.
Hi,
Eazfuscator.NET developer is here. Please be aware that Eazfuscator.NET 3.3 was released long before VS 2015 and thus was never tested with newer .NET Framework versions and Roslyn-based compilers.
This is important because we know that there are a lot of omissions that come to the surface in Eazfuscator.NET 3.3 + VS 2015 combo. More details are available in a dedicated "Visual Studio 2015, Roslyn Compilers and Obfuscation" article.
In this article I will explain our genuine experience with various .NET Obfuscator Tools. We end up explaining that .NET Reactor is the one we choose to obfuscate our code for various reasons: reliability, support, seniority, cost and obfuscation options.
Our code was compatible with an older version of Dotfuscator for .NET 4.0 and 4.5, but after migrating to newer versions like .NET 4.7.2 and .NET 5/6/7, we needed a more updated obfuscator. While Dotfuscator can handle these newer versions, they recently increased their subscription price policy by 50% each year without added value or an upper limit. This greatly multiplied our yearly fee after a decade of use.
Instead, Eazfuscator.NET encrypts obfuscated symbols with a private key. Thus production stack traces can be decoded with the private key. At first sight this is pretty cool. However there are two significant problems with this approach.
Initially, .NET Reactor did not work for us due to resource unavailability and some unobfuscated override method names. However, after several rounds of communication with the author, we were able to generate a bug-free obfuscated version of our code. The support we received was prompt and efficient. Now we have a reliable obfuscation process with excellent support, and all for less than 5% of what we used to pay with Dotfuscator.
There are many obfuscators for different languages, and some of those offer reversible options for easier field debugging. Eazfuscator.NET is one of these and with a bit of reverse engineering, whole files can be restored with the original symbols once you have the password.
Looking at the memory also revealed the salt, the above one was used to generate the IV, and another static salt was used to derive the actual AES key. It seemed so that they used AES in CBC mode, deriving the IV from the password in the same way as with the key, only they used a different salt.
Further dynamic analysis proved that they had a last layer of defense in the form of XORing the plaintext before AES encryption with a single byte, and appending this byte to the plaintext. Removing this trailing byte and performing the XOR operation on all the remaining bytes resulted in the expected symbol name.
ah ok found some dev tools for EAZfuscator ther dont work for this version ther work for EAZfuscator but not this version ther only need to updatet.
And how you found the key for the resources?
And i know so far that this tool fu with you if you us dedot because of the anti dumper dector or is that future not used in this unpackme?Damit i dit see this num 23+= with out using breakpoint and thx for that with the il instuction now i can remove the anti temper and then de4dot can be used normal
Hello ElektroKill, im new on this community, i didn't found a way to "devirtualize" a code, actually im trying with this and another packed executables and stuck in this -> " class.method_68(stream_, "=]em59jM+4", array);" i can see what "=]em59jM+4" means in dnspy, but i want to decode all correctly likee you show in your pictures, Can you guide me to achieve it?
Question is simple, those who are experienced with such tools, what it the level of protection such tools offer? Against what kind of attackers can they protect? yeah I know everything is breakable. But there are plethora of such tools, so they must give "some" protection right?
Bottom line, any obfuscation is useful since it makes the task harder and therefore the number of potential attackers less due to skill/time requirements. You can also attempt to write your own obfuscation tools that would prevent someone from just using a tool such as those mentioned above. However, this is similar to saying you could just write your own encryption library. Not a easy task to accomplish without years of experience.
Why can programs written in C# be reverse-compiled essentially to their original form with variables names (such as dnSpy) while C++ decompilers (such as Ghidra) are unable to decode the variable names?
Debug Symbol information is often "stripped off" from C++ binaries. Symbol information stores all user-created names, symbols, and types, bounds, fouction boundary and other function related metadata information (it is generally stored according to a popular and standardized "dwarf" format which is widely used and employed in modern compilers). If you want to keep this information then compile your binary with - say -g flag in gcc or clang. For e.g. gcc -g myprog.c. You will find all user-defined symbols rendered by Ghidra.
Delete the post build code after processing. Otherwise you will have problems with debugging your application in the future. You can also use the code below, the code is only obfuscated when running Release mode.
Testing the obfuscated files with this free Obfuscation Checker, you will see the generated Dotfuscator code has very few differences to the original code, i.e. it does not make much sense to obfuscate your code with the Dotfuscator Community Edition.
