Hey fellas!
This is an example for a simple brute force algorithm in C++ ✌
I commented it with my weird english skills as good as I could, and I hope that the C++ beginners, to whom this is adressed, are able to understand what I wanted to say. Maybe it's even something like a lil tutorial on brute forcers 😉
As you see, it's open source, so feel free to use it for whatever you like(transfering it to an md5hash "decrypter", for example, shouldn't be too hard...).
The syntax ain't perfect, I'm no C++ pro 😑 Anyway, I like the "mise en abyme" procedure in brute force codes, and although there are way faster codes out there(multithreading etc... going to learn this shit ^^), this one gives a cute little insight into the functionality of brute forcers, I think... 🤝
Blablabla, here it is:
btw, I worked with Visual Studio C++ 2010 Express on a windows XP 32bit system
EDIT: why does the forum cut every textline that contains more than 2 equal letters? 😵 wtf?
EDIT2: fixed some stupid grammar mistakes and added a pw_found-request at the end of in main(), behind the for()-loop
EDIT 3: THE NEW MULTITHREADED CODE
Okay dudes, now THIS is fucking awesome...
You may know that the key of a good bruteforcer is its SPEED.
I google'd a lot on multithreading and found this: http://www.boost.org/ 🤗
This really drives me crazy. Some godlike nerd called Anthony Williams created a multithread-library(simply called "thread") for this great code collection. I was immediately like: ✌ and 😈 !
It was easy to install and apply to my project.
AND NOW COMES THE CLUE!
With only two parallel-running bruteforce engines(this is just the beginning... if you want, you can use 123123123 billion, i think 😎 ), my new code rapes the string "asdf" in LESS THAN A SECOND!!! I'm still so fucking shocked. To compare, my old code took 18 seconds(!!!!) to bust this fuckin simple 4 character string 🤮
Accordingly, my new multithreaded brute force attack is about 1800 % faster :D
WHAT ABOUT THAT?!?!?! MWAHAHAHA
You'll need the boost-library thing to compile the source code, and its damn big, thus I uploaded the prog right here(I swear that it contains NO MALWARE! would be <3ly if someone could proof this with an virustotal scan report.)

heres the code, I didnt give a fuck on new // comments this time. was too excited. furthermore, I had to cut the bruteword outputs out, cuz cout sux on multithreaded applications and I was too lazy for printf'ing this(i don't even know if printf works correctly).... who cares. you'll still love it.
