I actually don't have ophcrack, and when I downloaded it it mentioned I'd need to download a fairly large table; given my crappy connection here, it would probably end up taking way too long.
A question about rainbowcrack: assuming I sort the first table I create (rtgen lm alpha-numeric 1 7 0 2400 40000000 all), would I still be able to go back if it didn't work and create the other 4 the tutorial suggests, or would the act of sorting it preclude this? I realize it's probably a stupid question, but the tutorial's a bit confusing.
