Re: Rainbow Tables




Thank you all for the great suggestions! I now have some great resourses from where I can pull the info I need.


Now, I've got a good one for you which may be a challange to come up with a solution.

I have now been tasked to take a list of passwords and try to generate a precomputed hash table out of those passwords...not sure if this can be done but of course I have to find a way..since I am "holding up a project".

Reason for this...the idea is that if we take the current list of passwords create a pre-computed hash table the next time we audit we'd run LC5 (till I convense them otehrwise) and all but the passwords that changed and new accounts would get knocked out right away.

Does anyone have a hint as to how I should do this? Is there a way to take the hashes and the cracked clear text and merge them into a table?

What is the best application foir creating pre-computed hash tables, that will work with LC5?

Thanks again for your help and the great suggestions!!

Tony
