NAME
       groar - password cracker

       crypt - crypts a password

SYNOPSIS
       groar -p passwd -f format [ -s ] [ -w dico ] [ -i ] [ -v ]

       groar -V | -h

DESCRIPTION
       groar is a password cracker. Its  primary  purpose  is  to
       detect  weak passwords using a large number of crypt algo-
       rithms. Known crypt algorithms are DES, MD5, BF, SHA1,  LM
       & NTLM with & without challenge / response.

       groar  is  a  temporary name for the older (but never pub-
       licly released) sha1_crack package. groar is going  to  be
       renamed  dru as soon as formats with salt are supported (I
       hope very soon).

       By default, groar prints the number of previously  cracked
       passwords and exits.

       The  different crypt functions are coming from OpenBSD 2.5
       (DES, MD5, BF) and the Unix L0phtCrack v1.5 (LANMAN & NTLM
       with & without challenge / response).

       This package needs OpenSSL installed in /usr/local/ssl/ to
       compile and have been tested only with the 0.9.4 and newer
       versions. Look at <http://www.openssl.org/> .

       Note  : now autoconf looks in some standard directories to
       find OpenSSL. You can specify where OpenSSL  is  installed
       (--with-openssl)  or  if  the  system  is OpenBSD (--with-
       openbsd). Old OpenSSL and ssleay should be detected  auto-
       maticaly.

       Attention  :  this  is  groarware, with a little chance it
       compile, it Seg.Fault regularly and it  may  infringe  one
       hundred of copyrights and licences.

OPTIONS
       -p passwd
              Specifies the password file.

       -f format
              Ignored: not yet implemented, actually only SHA1 is
              known.
              Specifies the crypt algorithm to use: DES, MD5, BF,
              LM, NTLM or SHA1.

       -s     Activates single mode: tests the login as password.

       -w dico
              Activates word mode and specifies  the  dictionnary
              file.

       -i     Activates  stdin  mode:  reads the dictionnary from
              standard input.

       -v     Shows previously cracked passwords.

       -V     Shows program version and exits - no crack.

       -h     Shows help and exits - no crack.

FILES
       groar.pot
              Every cracked password is saved in that file.
              That file is loaded after  the  password  file  and
              before any crack.

ENVIRONMENT
       none   as far as I know

DIAGNOSTICS
       todo   but not prioritary

BUGS
       groar  used  md4 files aren't 64 bits compliant so ntlm is
              broken on 64 bits systems.
              TODO: use md4 functions from OpenSSL (>=0.9.6) when
              available  or  use  local  copies of md4 files from
              OpenSSL when unavailable.

       groar  only knows saltless formats : CLEAR , LANMAN & NTLM
              without  challenge  / response and SHA1 crypt algo-
              rithmes.
              doesn't know DES , MD5 , BlowFish , LanMan  &  NTLM
              with challenge / response and APOP

       groar  The  password file must have the format login:pass-
              word.  Passwords mustn't have any prefix as  {sha1}
              .

       groar  no configuration file yet.

       groar  no rules option yet.
              Passwords generated by John the Ripper are so great
              that if it's implemented it will be basic.
