    LC5 Hash Tables

    Hey folks!

    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.

    Hello all,

    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...

    Thanks!!

    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.
