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.

ngorca -f hashlist -c3 -l6 -t2 -v4
