Thread: D4rk-cracker : A md5 cracker in python Share/Save - My123World.Com!

  1. #11
    This is a good start. I don't know if you guys have considered the following options, but anyways, my few cents on how this could be improved:
    1. Generate rainbow tables using Philippe's time-memory tradeoff technique on a cloud system, build a web app/service around to crack an MD5 (http://project-rainbowcrack.com/)
    2. Use an array of free web services (www.tmto.com anyone?) to get the hash. The following links have multiple links to such services:
    - http://www.stottmeister.com/blog/200...md5-passwords/
    - http://carnal0wnage.attackresearch.c...-crackers.html
    Best of Luck!

    exactly buddy however if you look at the links i provided they all don't have captcha... and 2 have there own API too... I am just a started at python right now so won't be able to help much however i have provided rresources for the eager minds.

    that's exactly what we are trying to do aggregate results from all other sources.

    building a cloud app will have its own cost implication's.
    we can think of that at a later stage.

    I posted few links as well as code has 3 sites already marked in for this same purpose

    i think as per pune meet , we are using our hardware for cracking the Md5...

    We can use the CUDA sever for cracking the Md5



    Full information about CUDA Server

    Code:

    one of the my friend having this hardware
    testing 3.870.000.000 MD5 by second.

    we have

    Old computer with linux
    Geforce GTX 480 superclocked
    Geforce GTX 570
    oclHachCat cracking software
    its gives awesome performance ... with Speed.GPU: 3800.2M/s
    Garage4Hackers bugs for the community , of the community

    We provide IT

    This is one Topic that really aligns with what I am doing right now!

    Nice!! Decryption of different types of hashes. My choice:

    Have you guys considered setting up an MPI Cluster between multiple Machines running a Linux OS? You can utilize multiple cores of a Processor with John the Ripper!

    JTR doesn't have much bandwidth requirements, so we can make use of NFS to setup Network Shares between all the machines.

    You even have an option to utilize a specific number of cores out of total. For instance, use only 3 cores out of 4 of an i7 processor!

    This suggestion goes as an alternate to the above...

    The most powerful way to cracking these days is by making use of GPUs!! Who buys GPU's for gaming anymore? :P

    Previously it was just the Nvidia Graphic Cards with CUDA support which could be used for Cracking Hashes using the Parallel Processing Power of GPU...

    But now we have oclhashcat by Atom, which adds support for the ATI Radeon Graphic Cards as well...

    Infact I was planning to invest in one such Machine. A few days back, I got the idea of having a dedicated Online Decrypting Server which hosts a myriad of tools. And it has options to run cracking on both, GPUs or CPUs...

    And I am so glad to find this thread and people with like minds!

    I will compile a list of all the tools out there which we can make use of. Along with this, we need to shortlist the Hardware Devices also..

    Whether we should go for Nvidia CUDA or ATI Radeon GPUs?

    More on this later!!

    Anyone tried this cracker ? http://www.golubev.com/hashgpu.htm ? it uses gpu to crack hashes and works with both ati and nvidia(uses opencl)
