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 calcula-
	      tion 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
