PHPBB3 Code
Windows is a total pain. I spent ages trying to get this phpbb3 code to compile on it. The code is messy as anything. It was written pretty fast just to do the job. I might release piratebay if people are interested which has a lot cleaner code in it. I actually used separate modules 
.
The code just runs through the entire phpbb3 captcha and fills in areas until it finds a small area. It assumes that any small area must be part of the letter. It then blurs all the little squares together, spaces the letters out better, rotates them and dumps a file that can be read by gocr.
The windows executable barely compiled. Hopefully it works, but since I don’t use windows. I have no idea really .
Here it is. PhpBB3 Crack tool

[20:17] wysiwtf@debian ~/temp/phpbb3crack ./compile.sh
crackbb3.cc: In function ‘int main(int, char**)’:
crackbb3.cc:689: error: ‘class Magick::Image’ has no member named ‘extent’
Any idea?

Looks like an old imagemagick package. You might have to install from the source from the imagemagick website. Make sure you remove all previously installed imagemagick packages.
Then pray.

Anyway, thanks - great piece of code

What distro you using then Harry?

Zenwalk Linux. A slackware derivative. Slackware is a brilliant distro but they have a habit of stuff not quite working as you’d expect. Slackware is almost bullet-proof though. Zenwalk takes that bullet-proof design and makes stuff work as well.

Hmm, not bad i also used gocr, but i have little problems witd pnm-s.
Anyway my clean-up script is writen in PHP(GD) but that’s not problem .. the problem is that gocr doesn’t read letters correctly. Here …

ok, there are some circles but i’ll remove that too. But if i remove that manualy and put it in gocr with pnm-s from zip in that post. Gocr regonize ONLY mybee 2 or 3 chars not more .. is that normal?

Hmm, I looked one more time all files in that zip. And ofcorse crackbb3.cc. And i would like to ask you, how can i rotate images ? How to calculate engle ?
September 8th, 2008 at 9:20 am
Ok I gived up, and I don’t think anymore how to rotate images. Insted of this I looked phpbb3 captcha generator, now if you play with this:
$this->basis_matrix[0][0] = -2;
$this->basis_matrix[0][1] = 1;
$this->basis_matrix[0][2] = 1;
$this->basis_matrix[1][0] = 1;
$this->basis_matrix[1][1] = 1;
$this->basis_matrix[1][2] = 1;
actuatly if you change $this->basis_matrix[0][0] to 10,5,2,-2,-5,-10 you can rotate letters as you want to all engles …
You can also generate one by one letters. Then you clean up images, and save letter. The last thing you need to do is to convert results to pnms and we have full database for phpBB3

Hi, great post! I have a problem, I managed to compile it succesfully both on windows ( vista with visual studio 2005 ) and on ubuntu 8.10 ( gcc 4.3 ) but when I run the binary It throws a floating point exception. The problem is in the function shift_overlap, but if i comment it out i get a white image, and I think this is the real problem, more than the floating point error ( cus it shouldn’t be white! there should be something in ). May It be because of the too new compiler? ( since the project is in vs6 ) Thanks in advance!
