NAME
       create-cracklib-dict - Check passwords using libcrack2

SYNOPSIS
       create-cracklib-dict wordlist ...


DESCRIPTION
       create-cracklib-dict takes one or more word list files as arguments and
       converts them into cracklib dictionaries for use by  password  checking
       programs.  The results are placed in the default compiled-in dictionary
       location.

       If you wish to store the dictionary in a different  location,  use  the
       cracklib-format and cracklib-packer commands directly.

NAME
       cracklib-format,	 cracklib-packer, cracklib-unpacker - cracklib dictio‐
       nary utilities

SYNOPSIS
       cracklib-format file ...

       cracklib-packer cracklib_dictpath

       cracklib-unpacker cracklib_dictpath

DESCRIPTION
       cracklib-format takes a list of text files each containing  a  list  of
       words,  one  per line, It lowercases all words, removes control charac‐
       ters, and sorts the lists.  It outputs the cleaned up list to  standard
       output.	The text files may be optionally compressed with gzip(1).

       If  you supply massive amounts of text to cracklib-format you must have
       enough free space available for use by the sort(1) command.  If you  do
       not have 20Mb free in /var/tmp (or whatever temporary area your sort(1)
       command uses), have a look  at  the  /usr/sbin/cracklib-format  program
       which is a sh(1) program.  You can usually tweak the sort(1) command to
       use any large area of disk you desire, by use of the -T option.	crack‐
       lib-format has a hook for this.

       cracklib-packer	reads from standard input a list of sorted and cleaned
       words and creates a database in the directory and prefix given  by  the
       command	line argument cracklib_dictpath.  Three files are created with
       the suffixes of .hwm, .pwd, and .pwi.  These three  files  are  in  the
       format  that  the FascistCheck(3) subroutine, cracklib-unpacker(8), and
       cracklib-check(8), utilities understand.	 The number of words read  and
       written are printed on stdout(3).

       cracklib-unpacker  reads	 from the database in the directory and prefix
       given by the command line argument  cracklib_dictpath  and  outputs  on
       standard output the list of words that make up the database.

       The  database  is  in a binary format generated by the utilities crack‐
       lib-format(8) and cracklib-packer(8).  On a Debian system the  database
       is  located  in	the directory /var/cache/cracklib/cracklib_dict and is
       generated daily with the program /etc/cron.daily/cracklib.   The	 loca‐
       tion  is	 also  defined	in  the header file crack.h using the constant
       CRACKLIB_DICTPATH though none of the subroutines in  the	 cracklib  li‐
       braries have this location hardcoded into their implementations.


FILES
       /var/cache/cracklib/cracklib_dict.[hwm|pwd|pwi]
	      cracklib dictionary database files used by utilities.

       /etc/cron.daily/cracklib
	      cracklib	daily  cron program to rebuild the cracklib dictionary
	      database.

       /etc/cracklib/cracklib.conf
	      cracklib configuration file used by the cracklib daily cron pro‐
	      gram to rebuild the cracklib dictionary database.

       /usr/include/crack.h
	      cracklib header file defining the subroutine FascistCheck(3) and
	      the constant CRACKLIB_DICTPATH used to compile in	 the  location
	      of the cracklib dictionary database for these utilities.

       /usr/sbin/cracklib-format
	      cracklib	shell  script to create initial list of words for dic‐
	      tionary database.

NAME
       cracklib-check - Check passwords using libcrack2

SYNOPSIS
       cracklib-check [-h|--no-echo]


DESCRIPTION
       cracklib-check takes a list of passwords from stdin and checks them via
       libcrack2's FascistCheck(3) sub routine.


OPTIONS
       --no-echo
	   Don't echo the password which is ok to the terminal.

       -h, --help
	   Print help explaining the command line options.


RESULT
       cracklib-check prints each checked password and the  corresponding  re‐
       sult of FascistCheck(3) to stdout. The password and the result are sep‐
       arated by a colon.  When --no-echo is specified, prints only the result
       if password is ok.

NAME
       update-cracklib - Regenerate cracklib dictionary

SYNOPSIS
       update-cracklib


DESCRIPTION
       update-cracklib	 builds	  a  compressed	 and  accumulated  version  of
       wordlists stored in the directories given in  cracklib's	 configuration
       file  /etc/cracklib/cracklib.conf.  Programs  using cracklib2 need this
       database to be of any use.

       By default this script is called by cron every day.


RESULT
       update-cracklib prints out two numbers: the number of words  read  from
       the  ASCII dictionaries and the number of words eventually written into
       the cracklib database; if no error occurred, these should be equal.

       0 is returned on success, otherwise an  error  message  is  printed  to
       standard error and -1 is returned.


FILES
       /etc/cracklib/cracklib.conf
	      shell  script  that  sets	 cracklib_dictpath_src which must be a
	      space separated list of source dictionary files.
