Hash Cracking with Rainbow Tables

This document explains the rcrack program. The rcrack program lookup existing rainbow tables for the plaintext of user supplied hash.
Six similar programs are available:

HashKiller.co.uk allows you to input an NTLM hash and search for its decrypted state in our database, basically, it's a NTLM cracker / decryption tool.

We have a total of just over 312.072 billion unique decrypted NTLM hashes since August 2007.
Please input the NTLM hashes that you would like to be converted into text / cracked / decrypted. NOTE that space character is replaced with [space]:
Please note the password is after the : character, and the NTLM hash is before it.

How CrackStation Works

CrackStation uses massive pre-computed lookup tables to crack password hashes. These tables store a mapping between the hash of a password, and the correct password for that hash. The hash values are indexed so that it is possible to quickly search the database for a given hash. If the hash is present in the database, the password can be recovered in a fraction of a second. This only works for "unsalted" hashes. For information on password hashing systems that are not vulnerable to pre-computed lookup tables, see our hashing security page.
Crackstation's lookup tables were created by extracting every word from the Wikipedia databases and adding with every password list we could find. We also applied intelligent word mangling (brute force hybrid) to our wordlists to make them much more effective. For MD5 and SHA1 hashes, we have a 190GB, 15-billion-entry lookup table, and for other hashes, we have a 19GB 1.5-billion-entry lookup table.
You can download CrackStation's dictionaries here, and the lookup table implementation (PHP and C) is available here.
