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:
              NETGARAGE:5D7F5FD88AE4C07F:EAC3EAC57FF0635AB298EB40CBDA1BB45DFC1B7F20464AA591C1613A2CB8

       -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
