NAME
ngorca - Password recovery tool for Oracle databases
SYNOPSIS
ngorca [ -f hashfile ] [ OPTIONS ]
DESCRIPTION
ngorca is a multithreaded password recovery tool using exhaustive key
search for Oracle versions 7-11g Rel.2. Due to the weak hashing
algorithm and constantly improving hardware performance, passwords can
be found in minutes, depending on their length.
OPTIONS
-f hashfile
To use ngorca a list of usernames and hashes is required, which
has the format username:hash. The username has a maxiumum length
of 64 characters and the hash is always a 16 byte hex value. If
the 11g algorithm is used a 40 byte SHA1 plus 20 bytes salt must
be added. The hash values are calculated one after another.
Example of hash file entry with old DES hash and SHA1 hash:

-l password length
The length of the password. If this option is not set, passwords
with the 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 alpha numeric.
-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. Per default one thread is
used.
-o logfile
A logfile could be specified. It contains the passwords which
are found and some info messages. The default logfile name is
ngorca.log placed in the directory the binary runs in.
-v verbose level
Loglevel for the logfile and standard output 1-4 with 4 as the
highest level which contains percent printouts. The default
loglevel is 1.
EXAMPLE
ngorca -f hashlist -c3 -l6 -t2 -v4
