![]() ![]() Lets get cracking Hashes in hand, start up Ophcrack: Then click load, PWDump file, and select either the hashes you got from pwdump2, my sample hash file, or some other source of SAM hashes: The last thing we need to do is load our rainbow tables. If youd like some hashes to play with, here are hashes for users with passwords varying from length from 1 to 7 characters long: test-hashes.txt.

Make sure you choose to download the tables seperately: Youll notice a lot of GTK files being installedthats nothing to worry about. Youll need a significant amount of memory to load this rainbow table. Setting up shop The first thing you need is the software and rainbow table sets. ![]() If you want to try cracking passwords, please obtain hashes from your own machine, or use the example hashes I provide here. Please note that federal law prohibits the possession of unauthorized access codes to computer systems. The technology it uses to break Windows passwords is called rainbow tables and was described by Philippe Oechslin in Making a Faster Cryptanalytic Time-Memory Trade-Off.Ī rough way to describe this technique is to say that tables of possible hashes are precomputed so that you can iteratively compare the windows hashes to precomputed bits and piece together the hash and its value more quickly than brute-force guessing. ![]()
