NAME

       cracklib-format,    cracklib-packer,   cracklib-unpacker   -   cracklib
       dictionary 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
       characters, 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.
       cracklib-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
       cracklib-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
       location is also defined in the header file crack.h using the  constant
       CRACKLIB_DICTPATH  though  none  of  the  subroutines  in  the cracklib
       libraries 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
              program 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
              dictionary database.
