ngorca Note:

-f hashlist
To use ngorca a list of username and hash is required, which has the format
username:hash. The hash values are calculated one after another.
example of hash file entry with old DES hash and SHA1 hash:
NETGARAGE:5D7F5FD88AE4C07F:EAC3EAC57FF0635AB298EB40CBDA1BB45DFC1B7F20464AA591C1613A2CB8
<username>:<16 byte DES hash>:<40 byte SHA1 hash + 20 byte salt>
In oracle versions 7-10g there is only the DES hash.

-l password length
Length of the password. If this option is not set the passwords from a length of 5-8 bytes are calculated.

-c charset
The charset of the password. 1 for numeric, 2 for alpha, 3 for alpha numeric
and 4 for alpha numeric with special characters. The default is 3.

-v verbose level
Loglevel for the logfile and standard output 1 - 4 with 4 as the highest level
which contains percent printouts. The default is 1.

-t thread number
The number of threads which should be used. It is recommended to take the
number of cpu's which you want to involve in the calculation for the best
result. The default is 1.
