For just $17, CloudCracker.com lets anyone run their WPA-PSK hashes against a dictionary of 604 million words, or step-up to 1.2 billion words for $34. If one wanted to throw everything at a given hash, including the kitchen sink, then there is an option for $136 that will use 4.8 billion words. Aside from WPA-PSK, CloudCracker can also tackle LAN Manager and NT LAN Manager hashes for a cost of $0.50 per recovered password.
The service is great for penetration testers and network auditors who need to check the security of WPA2-PSK protected wireless networks, crack password hashes, or break document encryption.
