Yeah.. the lovely SMALL rainbow tables Laughing
Here's a link I found through google, there's direct links to download rainbow tables:
http://rainbowtables.shmoo.com/

Oops! I thought I read that 42Gb as 42KB Shocked
But, it sounds small, right? Laughing

EDIT: UCM: using your version, everytime I click "Find" with or without any hash the program closes itself Shocked Not very handy


Has somebody webspace for me ?
Can upload over 100GB of Tables lol Laughing

IF somebody has Webspace THEN : can you give me some ?

It would be very very good if it were Webspace under Linux with some limited shell access Very Happy

saigon, I don't see how it's possible that you would get 'Thread already running'. (by the way, that is from the application, not windows)
The code has:
Code:
  findT:
        test    [running],1
        jnz      already_running
        mov     [running],1
        invoke  CreateThread,0,0,find,0,0,[thid]
        mov     [th],eax
        test    eax,eax
        jnz     finish
  already_running:
        invoke  MessageBox,[hwnddlg],err_running,NULL,MB_OK+MB_ICONWARNING
        jmp     finish       
    

'running' has been declared with 'running db 0' in the data section. If you test 0 with 1 (AND), you get 0, which should NOT trigger 'jnz'. That's really, really, really odd.

I always thought that rainbow table just makes a normal table and searches it, but that way it would take too much space, so it never got my attention Very Happy Now i see that its much more behind it:

However salting kills the rainbow Sad
So we still need bruteforce Very Happy

Hey , does somebody know Boinc ?
Maybe we can make a Boinc Project wich uses this FASM app.. And so it can convert a 16 Chr md5 in under <10sec.. Very Happy

- Boinc is distributed computing..

Has somebody here worked with Distributed computing ?
If yes i need more info.
Keywords: Linux, Debian ..

@sylwek32: I have not, but sounds interesting... if you can crack a MD5 hash with 16 characters in under 10sec, then WOW! And, BTW: Nobody gives 100Gb for free, people might think you want to upload illegal stuff ..

@UCM: I tested the running variable and yes it's zero, but the program still alerts that the thread is running. I know this is very odd, but I'm not lying.

Maybe the thread is not being created properly, and the code is (accidentally) running into the already running part... (bug on my part)
Try using this version, if it just closes then the thread wasn't created
Note: this version has a 'Clear' button Very Happy
EDIT: There may have been a different bug too, fixed that as well

UCM, that version works perfectly! I don't get any error and the program recovers the passwords quickly (Your version seems to be faster than Turok's). Thanks a lot!

Have one question.. again :/..

How to make it run under dos shell or in CMD?

It would be great if it can work in Commandline.
- Accept commandline args..
- Show output in console...

Like this! Razz
Maybe I have too much time on my hands.
This program tries to detect what part of the command line is its own program name, and the 32 characters of the rest (after the space, of course) are used as the MD5 hash. If there are less than 32 characters it is supposed to report an error, but it doesn't work (for some reason.)
If you run it normally, you will see 2 of the resulting string corresponding to the hash. This is because it can be redirected to a file or piped to a different program, and the string alone will be sent and the rest will go to the console. (Check the source and try 'md5prtwin32con 12227AC1EA36D1AB2C0656099BE9F8CB > blah.txt' to see what I mean.)

EDIT: Well, I fixed it now.

@UCM : Thanks.. Works good! Faster than the GUI version Very Happy

Ps: it works only at 1 Processor at a Dual Processor machine , right ?

Is it a lot of work to make it run under 2 CPU's ?
I want to use the Full power of my Tyan Tiger 2xAthlonMP 2000 machine Very Happy

Greetings...

Hi you all !

And now it´s ~6KB !!

That´s very nice for a MD5 recovery tool Very Happy

And then you embed a 600K xm track and make the executable image 100 times bigger Smile

i think a progress bar or just simply a turning "/" char would be fine to see it working

and hmmm being able to chose character set, casing, numbers Smile

Hello guys, if you use 128-bit xmm registers, you'll be able to calculate 4 hashes every cycle (really speed-up).
Download lovec64 from my home page (has brute force password generating routine for 4 passwords in 1 cycle too).

Maybe somebody can add a code which shows on what time a function beginned...

Sorry for that english^^

So:

- 19:00 - MD5 RECOVERY STARTED
- 19:01 - CHARS: 5
- 19:44 - CHARS: 9
- 20:00 - Found = [RESuLT]

or an external log file with all informations...

e.G. CPU Type , Speed , Recovery Speed , and..
you know..

I wrote a brute-forcer that is quite a bit (at least 100%) faster than this program. It also tells you how long it took to crack the hash. Link below to my post. Smile
