Having good rainbow tables is essential for any good hacker / pen tester. A rainbow table for cracking local machine hashes that include every possible character should be around 32GB in size. Average crack time being 53 minutes.
You can either buy or build your own rainbow tables or download from bitTorrent. Rainbow tables are created using the program 'rtgen' or for windows 'winrtgen.'
BitTorrent tables maybe obtained for free at www.freerainbowtables.com
Rainbowtables can be bought on removable media or preloaded hard drives.
You can pay for a subscription to Rainbow-crack online Which seems to be offline at time of writting.
