wordlist generator

Postby stasik » Tue May 20, 2008 2:04 pm

A while ago i was looking for a wordlist generator that will create words of given character set and could not find any, so i decided to write it myself. The soft will generate all possible words of given character set, of defined length and save them to a text file. This is useful for the bruteforce attack when char set is known or at least partially known. Generating all possible words for the full alphabet will take time and space. Before generating words, it will display the number of words which will be generated, and the final size of the text file, so the user will have a rough idea of time/size. While generating, the soft will display: actual word, percentage of the work done, time elapsed, time left, speed and actual file size in perioud chosen by the user. The character set inputed by the user will be sorted and duplicates will be removed.

Edited: user have the option to select fow often the progress to be displayed

Very nice, mate, truly - I was about to code one of those myself, actually.

However, please post the source-code. Most of us are going to be reluctant to download and execute .exes from people on the internet, and then there's the obvious learning experience to be gained from reading the source-code.

Also: I can give you a hint without seeing the source-code - it looks as if you're actually displaying every single permutation of the data. This means that just purely lowercase alphabetical password will need 11881376 statements to be printed. This is important, because printing to the console is probably one of the slowest operations. I guarantee you that without printing output, the generator will be much faster.

Thanks for the reply. Indeed the soft is printing every single string generated. I ll put the delay to display the info every 5 sec or something like that. The code is a mess coz i wrote it during working hours at work and could be optimized, but i ll post the code anyway.
***
I edited the soft and now it displays the info every 10 sec, for 1 sec, and the speed is 100 times faster. Link to both exe and source code is available in the initial post. Thanks a lot for the hint!!!

If making it display every 10 seconds increased the speed 100-fold, why not take an approach like nmap where the user can decide when they want a progress report by pressing space or something similar. Waay less printing, yet still keeps the user up to date. It might even speed it up a bit more ;)

Oh man, that's what I feared.

Sure, your method works, but using loops and loops and loops and loops and repetitive code is not the way forth. When I finally code one, I'll show you the difference.

I ve told you its a mess.. Could not get rids of those loops as there are few similarities between them. Still can be used before any better one is out.

Don't get me wrong - it's good initiative, and the fact that you actually coded something this big is good. The code is also nicely formatted and indented, but it's just not programmed using an optimal algorithm, even though it's pretty fast.

However, even though optimized, the code is bound to have a lot of loops. One could do it recursively, but that's extremely inefficient.

EDIT:

Also, to explain what I mean; this code:
Code: Select all
while((strcmp (min_char,"1") != 0) && (strcmp (min_char,"2") != 0) && (strcmp (min_char,"3") != 0) && (strcmp (min_char,"4") != 0) && (strcmp (min_char,"5") != 0) && (strcmp (min_char,"6") != 0) && (strcmp (min_char,"7") != 0) && (strcmp (min_char,"8") != 0) && (strcmp (min_char,"9") != 0) && (strcmp (min_char,"10") != 0) && (strcmp (min_char,"11") != 0) && (strcmp (min_char,"12") != 0) && (strcmp (min_char,"13") != 0) && (strcmp (min_char,"14") != 0) && (strcmp (min_char,"15") != 0) && (strcmp (min_char,"16") != 0)) // make sure digit is entered { printf ("\n*********"); printf ("\n*[ERROR]* The input should be a digit between 1 and 16. Try again!"); printf ("\n*********\n"); printf ("\n minimum number of characters: "); cin.getline (min_char,array_length,'\n'); } if(strcmp (min_char,"1") == 0 ) {a = 1;} // if digit is entered, what integer? if(strcmp (min_char,"2") == 0 ) {a = 2;} if(strcmp (min_char,"3") == 0 ) {a = 3;} if(strcmp (min_char,"4") == 0 ) {a = 4;} if(strcmp (min_char,"5") == 0 ) {a = 5;} if(strcmp (min_char,"6") == 0 ) {a = 6;} if(strcmp (min_char,"7") == 0 ) {a = 7;} if(strcmp (min_char,"8") == 0 ) {a = 8;} if(strcmp (min_char,"9") == 0 ) {a = 9;} if(strcmp (min_char,"10") == 0 ) {a = 10;} if(strcmp (min_char,"11") == 0 ) {a = 11;} if(strcmp (min_char,"12") == 0 ) {a = 12;} if(strcmp (min_char,"13") == 0 ) {a = 13;} if(strcmp (min_char,"14") == 0 ) {a = 14;} if(strcmp (min_char,"15") == 0 ) {a = 15;} if(strcmp (min_char,"16") == 0 ) {a = 16;}
Can be replaced with:
Code: Select all
int minChar = atoi(min_char); if(minChar < 1 || minChar > 16) { printf("Min length must be between 1 and 16.\n"); // .. Do something about it .. }
Also, you should decide on which language you're using. If you're using C++, which is implied by the headers you include, and the use of the cin class - you should be using the string class, not C-style arrays(String class is MUCH better) and cout instead of printf.

You should also add "using namespace std;" below your include directives, and remove the ".h" in front of iostream, because iostream.h is deprecated.

However, most of all, you should also get a real compiler. What are you using? Try getting Code::Blocks, and configuring it to turn on the highest warning level.

I dont know about you, but when i start coding i like to write every thing the long way, make me understand better + make less error, then optimize/reduce what i can. I used C style as printf is faster than cout, or am i wrong? At work i use Visual Basic C++, but at home i compiled with Borland C++ 5.5. Its a bit old (2000) and its command line. When i tried to compile the code i got errors, but at work was working ok. Which compiler would you advise?
Also i looked into displaying the progress when the user press a key (space) but some library has to be imported and its a lot of work. Maybe the user should use the interval for the info display...

That's what pseudocode is for. But hey, whatever werks for you.

The newer compiler the better - it's bound to support newer standards. As to printf and cout, no, it shouldn't really be faster. The difference shouldn't be noticeable, really, since they both use the same way of writing to the console.

The only copy I could find is from March 4th, 2009.
I've copied it here:
http://coolfire.insomnia247.nl/hackerth ... rdlist.cpp

Also, look here for a Topic-45221
It only does one set length, but that's easily solved with an extra loop around it. I'm not sure if it's going to be any faster than the C++ one (probably not) but I would say it's a lot more comprehensible.
If we're breaking the rules, then how come you can't catch us? You can't find us? I know why. Cause, it's ... MAGIC!
