Need help making a BruteForce programme

[DrRoach]

Hey guys I've decided to make a brute force programme as a project to test my skills but I have no idea where to start. I just wanted to ask what language I should use. Thanks

Which ever language you prefer.

Are you trying to brute force with a dictionary or combinations?

Ok thanks I didn't realise that you could use any language.

Are you trying to brute force with a dictionary or combinations?

I'm going to try and use combinations but would you reccomend otherwise?

[KthProg]

Yeah it's really impractical to attempt brute forcing with combinations, because of the number of possible combinations.

I would use Ruby for combinations though, because you can use ranges like this [aaa...zzz] and it will test each combination 'between' them. i.e. aaa,aab,aac, etc.

But if you use something like this, find a compiler for it, because Ruby is normally interpreted and compiled programs are faster.

If you're trying to brute force an application, it could be slightly more practical to use combinations, since there's no lag.

There may be better ways to do this that other members here know too.
What they've usually told me though is to find a good dictionary list and try that first.

side note:
in most other languages, you have to create an array of letters and symbols and then use a bunch of nested for loops to iterate through each combination.

Thanks for the advice I decided to download a 10k most used passwords list from http://xato.net/passwords/more-top-worst-passwords/ to see if I can get the programme running and I'm going to try making it in ryby first but if I fail with that I'm going to try pyton.

Thanks to everyone who replied with advice

[KthProg]

cool, let me know how it goes.

Will do

I'm having trouble getting the array for the character input working. I am writing it in C and when I try and compile it says "error expected expression before { token"

Please can someone show me where I'm going wrong? Here's the code that has the error (it's in the second line) :

char alphabet_array[26];
alphabet_array={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};
for(k=0; k<10; k++)

Thanks

If you're planning on assigning letters to your array that way, you need to do it on the same line you initialize the variable in. Also, unless you declared the variables "a" through "z", you're going to need to put each on in-between single-quotes to signify that they're characters, not strings. So your code would ideally look like this:

Code: Select all

...
char alphabet_array[26] = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h' ... 'z'};
for(k=0; k<10; k++)
...

Thanks for the help I got it working
