Bruteforcing password

Aug 21 2020

Sehari yang lalu saya memulai proyek ac # di mana saya bruteforce password. Kata sandi dapat berupa bilangan bulat dan string. Dalam kode saya memeriksa berapa banyak karakter yang dimiliki kata sandi. Meskipun ini agak curang, butuh waktu terlalu lama untuk memecahkannya. Saya mempostingnya di sini untuk melihat apakah itu cukup baik.

using System;

namespace Hacking_Project
{
    class Program
    {
        static void Main()
        {
            //Console Color
            Console.ForegroundColor = ConsoleColor.White;
            Console.Clear();
            //If password is found
            bool done = false;
            //If the password is a string, not the best name but ok
            bool yes = false;
            //If the Guessed password is the same number of characters as the original password
            int pass = 0;
            //Guessed password
            string pass_check = "";
            //Possible characters for the password
            char[] pos = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j',
                          'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't',
                          'u', 'v', 'w', 'x', 'y', 'z'};
            Console.WriteLine("What is the password?");
            //Asking for the password to crack
            string password = Console.ReadLine();
            //How much characters does the password has. I know that this is kinda cheating, but then the bruteforce would take to much
            int digits = password.Length;
            //Initialising the random number generator
            Random rand = new Random();
            //The choices that the calculator will take for the guessed password(int)
            int[] choices = new int[digits];
            //The choices that the calculator will take for the guessed password(string)
            char[] choices1 = new char[digits];
            
            //If the password is a string
            for (int i = 0; i < pos.Length; i++)
            {
                if (password.Contains(pos[i]))
                {
                    password = password.ToLower();

Penafian: di bawah ini hanya pendapat saya, mohon jangan perlakukan itu sebagai sumber kebenaran. Juga, saya berasumsi bahwa kode bekerja persis seperti yang diharapkan - saya tidak akan memikirkan kinerja atau vailiditas.
