       FascistCheck - a pro-active password checker library


       #include <crack.h>

       static char const CRACKLIB_DICTPATH[] =  ...;

       extern char const *
       FascistCheck(char const passwd[], char const dictpath[]);


       cracklib  is  a  library  containing  the  FascistCheck  C function which may be used in a
       "passwd" like program.  The idea is simple: try to prevent users from  choosing  passwords
       that  could  be  guessed  by  "crack"  by  filtering  them out, at source.  cracklib is an
       offshoot of the the version 5 of the "crack" software and contains a  considerable  number
       of ideas nicked from the new software.

       The  first formal argument password is the potential password.  The second formal argument
       dictpath is the full path name + filename prefix  of  the  cracklib  dictionary  database.
       FascistCheck  returns  the  NULL pointer for a good password, or a pointer to a diagnostic
       string if it is a weak password.

       The database is in  a  binary  format  generated  by  the  utilities  crack_mkdict(8)  and
       crack_packer(8).   On  a Debian system the database is located in the directory defined by
       the static constant CRACKLIB_DICTPATH and  is  set  to  /var/cache/cracklib/cracklib_dict.
       None of the subroutines in the cracklib libraries have this location hard-coded into their
       implementations.  It is generated daily with the program /etc/cron.daily/cracklib.


              cracklib dictionary database files used by utilities.

              cracklib daily cron program to rebuild the cracklib dictionary database.

              cracklib configuration file used by the cracklib daily cron program to rebuild  the
              cracklib dictionary database.

              cracklib shell script to create initial list of words for dictionary database.

              Example cc(1) source files that show how FascistCheck is used.
