usage: rcracki_mt -h hash rainbow_table_pathname
       rcracki_mt -l hash_list_file rainbow_table_pathname
       rcracki_mt -f pwdump_file rainbow_table_pathname
       rcracki_mt -c lst_file rainbow_table_pathname

-h hash:                use raw hash as input
-l hash_list_file:      use hash list file as input, each hash in a line
-f pwdump_file:         use pwdump file as input, handles lanmanager hash only
-c lst_file:            use .lst (cain format) file as input
-r [-s session_name]:   resume from previous session, optional session name
rainbow_table_pathname: pathname(s) of the rainbow table(s)

Extra options:    -t [nr] use this amount of threads/cores, default is 1
                  -o [output_file] write (temporary) results to this file
                  -s [session_name] write session data with this name
                  -k keep precalculation on disk
                  -d run sha1 hashes against mysqlsha1 tables
                  -m [megabytes] limit memory usage
                  -v show debug information

example: rcracki_mt -h 5d41402abc4b2a76b9719d911017c592 -t 2 [path]/MD5
         rcracki_mt -l hash.txt [path_to_specific_table]/*
         rcracki_mt -f hash.txt -t 4 -o results.txt *.rti
