OK, so I downloaded the 119GB lm Rainbow Tables created by Hak5 and fans, and I am trying to use it to crack an lm hash. I am an IT security student in college doing a double concentration, I am not hacking anything illegally nor do I plan to, this is for education use only.
So after using "fgdump" to dump the hashes I used the the hash I wanted with the "rcrack" program included with RainbowCrack. I was able to use the Hak5 tables to crack a nine character password with upper and lower case letters, and symbols in nine and a half minutes. Yay! I then decided to use Ophcrack to do the same thing, and it didn't work. I have Ophcrack installed on both an xUbuntu machine and a Windows XP machine, both fully updated.
When I open Ophcrack, I click on the"tables" button, and tell it where my tables are located (on an external drive). Once I do that, the Windows version of Ophcrack says "You requested the tables blahblahblah, but some or all tables could not be found or loaded." The Linux version gives a similar error. I know the tables are sorted and working, because they worked with "rcrack".
Question 1: Why won't Ophcrack load my tables?
Question 2: What are some other good programs (including Windows ones, other than Cain) that work well with Rainbow tables?
Note: I may eventually turn this into a project for one of my classes (what are Rainbow Tables, how to build, get, use them). If I do that, Hak5 and others who have helped will definitely be mentioned.
Oh, and I'm seeding the tables right now, thanks to all the other seeders!
