Re: Saving the keys/hashes?

Use more than 100GB and you'll get kicked out. If you don't get kicked out for disk space you'll get kicked out for using 100% CPU for a few days straight.

Re: Saving the keys/hashes?

You want a LHT (Lossy Hash Table) but these can only be made with key spaces of at most a few trillion. 4.8 trillion is the largest and that's on 50 TB. It can be done with 16 TB and each lookup cost 2 hard drive seeks and about 160,000 MD5s. Add or subtract 600 GB each time you double or half the n...

Re: Best GPU Rainbowtable cracker

I'm not exactly sure which table set you are talking about because there is a 576 GiB and a 396 GiB, but way if you can afford those then you can afford a Nvidia GPU. Although it is possible to make a RT slower than brute forcing these are not they have a brute force point of 18825 (576 GiB) and 158...

Re: have anyone done this before?

Yes, only difference is most reverse the last 15 steps then go forward 16+16+13 steps and check a vs ra+data[0] then do the next steps as needed. You can also half reverse 2 more steps so you can skip about a step more worth of work.

Re: tobtu.com

It is a lookup site, where you at some point can enter queries. Transferring in on a 100 Mbps LAN (takes at least 67 hours at 100% and pure data [no tcp/ip headers]) is slower than recreating it (hoping for 30 hours probably going to be closer to 40 hours) so no you will not be able to download it. ...

Re: Rquest:Radmin 2.x algorithm

Nice this is a perfect example why you should never come up with your own algorithm that you think makes it hard to crack. This is equivalent to normal MD5 for cracking passwords. You will actually get slightly higher speeds with this than MD5 barswf. Since you only need to do one MD5 with no "0x80"...

BTW you will not get 2.9 times faster by reversing, if your program is only doing MD5 it will be about 1.4545 times faster. Your function to generate the next password is probably really slow.
