ngorcais a multithreaded password recovery tool using exhaustive key search. Oracle databases encrypt passwords with a simple DES encryption algorithm, as described by Joshua Wright and Carlos Sid in

'An Assessment of the Oracle Password Hashing Algorithm'. Due to the weak hashing algorithm and constantly improving hardware performance, passwords can be found in minutes, depending on their length.
ngorca supports multiple CPU cores by using threads. The number of threads can be set as an option. For optimal results it is recommended to use the number of cores that are present in the machine.
On a Intel(R) Core(TM)2 Duo CPU ngorca calcutates 1.6 million 6 byte passwords from an alphanumeric charset per second. This means that you need 23 minutes to find the correct password in the worst case.
Supported operating systems are Linux, BSD and MacOS.
