Difficulty : I don't know, but they say 10
Language : C#
Platform : Any Windows
OS Version : All
Packer / Protector : AssemblyGuard.io

Description:

You put the key and it will say "That's really correct!" if the key was correct.

I'd like someone who unpacked it to tell me how he/she did it 😕

NOTE: I want it to be unpacked, I don't want you to use Process Hacker just to get the key of the Unpackme file.

Thanks!

UnpackMe.exe

10/10 difficulty but that's a free modded ConfuserEx ? I don't understand anything in the scene nowadays .... also there claim to have bytecode encryption, bytecode for .NET ? Doesn't make sense ? 

@Rextor No Idea why you negged my answer ? 

 

@OP :

	{
