Ophcrack version 2.0. Ophcrack is a cracker aimed at NT-style (LANMAN) password-hashes. It uses a large precomputed hash database to crack the majority of all passwords within a matter of seconds, rather than hours or days as would be the case if you search the entire likely keyspace each time you are looking for a specific password. This type of cracking is based on a technique referred to as "rainbow tables".
