Mr Wolf Posted January 29, 2008 Share Posted January 29, 2008 First of all, thanks to all who make this possible! I'd like to collaborate! So, I downloaded these LM Rainbow tables: hxxp: www. freerainbowtables. com/rainbow_tables/lm. html through Bittorrent (38. 8 GB compressed, it took me about 2 weeks!) and I used them with Cain, successfully finding my password (and no! I'm not gonna tell you what it is!) and other ones (EH!EH!EH!). Not compressed, they are 66 GB. Then, I discovered Hak5 Rainbow tables: hxxp: www. torrentbox. com/torrent_details?id=101385 hxxp: www. torrentbox. com/torrent_details?id=82125 First of all, can anyone tell me what's the difference among the two? Reading the "Technical Details" I couldn't find any difference, in what way ver2 is better? Then, the essential question: why 120 GB, while the ones I downloaded are 66 GB? (Not considering the charsets are a bit different, if I'm not wrong, in the ones I downloaded there's the symbol € more). Ok, I read here: hxxp: wiki. hak5. org/wiki/Community_Rainbow_Tables among the FAQs that larger=faster, but is it that all? I read something about the theory behind Rainbow Tables, and there are some things that are not clear to me. What I can't understand is: smaller Rainbow Tables can crack exactly the same passwords of the larger ones? They are just slower? With the 66 GB Rainbow Tables I downloaded, it takes me about 1 hour to crack passwords (on a Pentium M 2 GHz), can anyone tell me more or less how much this time would be improved with 120 GB Rainbow Tables? Here is an image: http://img153.imageshack.us/img153/464/immaginecu8.jpg[/img] Actually, I read that with some Tables it takes only a few minutes to find password, and for example here: hxxp: ophcrack. sourceforge. net/faq. php the inventor of Rainbow Tables says that Rainbowcrack Rainbow tables "are neither optimized nor fast" And the Rainbow Tables he sells here: http://www.objectif-securite.ch/en/products.php WS-20k, should be about 10 GB. Any explanation will be useful, thanks! Quote Link to comment Share on other sites More sharing options...
