[C#] The real Brute Force by Mathian - Mathian - Dec 26, 2018

Hi! When I first heard about BruteForce, I imagined going over all the options from "a" to "z". I have created such code long ago, but it would be worth thinking about exceptions:

Code 
using System;

using System.Collections.Generic;

using System.Linq;

using System.IO;

namespace Cycle

{

    class Program

    {

        static void Main(string[] args)

        {

            string Chars = "Alphabet";

            for (int i = 0; i <= 3; i++)

            {

                foreach (var Password in GetCombinations(Chars.ToArray(), i))

                    Console.WriteLine(Password);

            }

            Console.ReadLine();

        }

        private static IEnumerable<string> GetCombinations(char[] Chars, int MaximumLength)

        {

            if (MaximumLength < 1) yield break;

            foreach (var a in Chars)

            {

                yield return a.ToString();

                foreach (var b in GetCombinations(Chars, MaximumLength - 1)) yield return a + b;

            }

        }

    }

}

With this code you can get absolutely all combinations of passwords, but it will take an incredible amount of time. I'm not saying that this is the best way (rather the opposite), but this is the real Brute Force.

better use Parallel.ForEach

By outputting every password to console, you're massively reducing the speed of the program

Oh my God! Friend, you can not output to the console. I provided the generation algorithm

RE: [C#] The real Brute Force by Mathian - .TheMarv - Dec 27, 2018

Code 
foreach (var Password in GetCombinations(Chars.ToArray(), i))

                    Console.WriteLine(Password);

This will output every possibility to the console, that's what I was referring to

@OP thank you for sharing this!

He has provided the algorithm to generate passwords, where you want them outputted is your choice 🤝

Ofc, I just wanted to point out, that putting it out in the console would decrease the performance.

You can save to file, add to database or apply. Conclusion in the console - a demonstration of work

Enjoy :)

Enumerators and IEnumerable = very slow. An iterative approach would be much faster. This code snippet is really not useful in the real world for relatively good bruteforcing.

I by no means suggest to produce brutus by this method
