LC5 Hash Tables
I have the newer version of L0pht Crack (LC5) and I would like to get ahold of the "precomputed hash tables". Anyone have an idea where to get those? Thanks.

Do a search on Google for "Rainbow Tables". That will get you started in the right direction. Also, take a gander at Password Cracking with Rainbow Tables in AO's Security Tutorials Section.

Just a note:
* Pre-computed password tables are not offered with the "LC 5 Professional" edition.
Experience is something you don't get until just after you need it.

I suppose that's why he's looking for them..

On the subject of pre-computed hashes, I "quickly" need an application or method, that will allow me to take a list of passwords and create a pre-computed hash table table to use in LC5, which would be the same as a rainbow table but using a list of passwords rather than a char set. The attempt here is to pre-compute the passwords so at a later date I can run LC5 and the session would run faster against the passwords that have not changed.
I know it is a bit out-of-the-ordinary but some people up the ladder don't understand how some things take time...

Pre-computed hashes are meant for computing all keyspace (aka pre-computed bruteforce). Since you only want to use a set of passwords, what you a really doing is a dictionary attack. Just make a dictionary file with the passwords and roll.
