This is command-line utility! Please run it from
command (DOS) prompt.

Please bear in mind you have quite no chance to crack unknown
password (longer than 6 symbols) if you have no additional
infor about it. So, the primary purpose for this utility is
to recover your forgotten passwords. 

To quick start password cracking:

1)  Rename one of "english.def", "spanish.def" or "russian.def" to
the "password.def" file

2) Read about password definition rules (section 4.2) until
you understand password definition examples from 4.4.

3) Change the password.def file below the '##' line
according the character set you will use.  To do it,
read section 4.2.1 of documentation. For example, if
you decide to use both case Latin letters and digits,
change password definition to
  [$a $A $1] *

4) Test your password definition using -v option.
You also may test the cracker on this archive.
Run:
   crark -pcrackme.def crark31.rar

5) Run the program

   crark your_rar_archive.rar,

6) If you have questions, read the FAQ (section 5) first.

7) Read the full docs, finally

  Please remember I almost have no time to support
this free utility, but I'll be grateful about bug reports.
Also I'm interested in benchmarking on rare processors,
like VIA-C7, Transmeta etc. If you have such a processor
you may send me the log file after running
   crark -b rar_file > log

   If you will make "password.def" file for other language,
send it to me please.

  Good luck!
