       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.
