using System;
using System.IO;
using WinRAR;

namespace ProtectedFileCreator
{
    class Program
    {
        static void Main(string[] args)
        {
            string fileToCompress = "example.txt";
            string compressedFile = "example.rar";
            string password = "your_password";

            using (var rar = new RarArchive(compressedFile, RarArchiveType.Create))
            {
                rar.AddFile(fileToCompress);
                rar.Password = password;
                rar.Save();
            }
        }
    }
}
