I understand that you have an assignment and so you are compelled to do
that. But, wouldn't it be easier to create a diccionary with the passwords
in clar text?. In fact I believe LC5 can create a diccionary with the
result of a session.

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
