KoiVM is a virtualizing protector for .NET applications, as a plugin of ConfuserEx. ConfuserEx is a open-source protector for .NET applications. It is the successor of Confuser project.

KoiVM is a virtual machine made to work on ConfuserEx, it turns the .NET opcodes into new ones that only are understood by our machine. There are multiple ways of using the plugin, first one is certainly ridiculous as it will "merge" with cex and virtualize every single method, including protections from ConfuserEX, however note that this might KILL your performance. Second one will just virtualize the methods that you decide, this is the best option in all if not all the cases.

I took KoiVM from https://github.com/BedTheGod/ConfuserEx-Mod-By-Bed (1.4.1) and modified it to make OldRod fail devirt.

using System;

namespace CrackMe
{
	internal class Program
	{
		private static void Main(string[] args)
		{
			Console.Title = "Made by robert";
			Console.Write("Key: ");
			bool flag = Console.ReadLine() == "key is not here, here is just the source code without the key lol";
			if (flag)
			{
				Console.WriteLine("Good Job");
				Console.ReadKey();
			}
			else
			{
				Console.WriteLine("Oof bad key");
				Console.ReadKey();
			}
			Environment.Exit(0);
		}
	}
}
