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
