.SH NAME
FascistCheck \- a pro-active password checker library
.SH SYNOPSIS
.B #include <crack.h>
.sp
.B "static char const CRACKLIB_DICTPATH[] = \ .\|.\|.;"
.sp
.B "extern char const *"
.br
.B "FascistCheck(char const passwd[], char const dictpath[]);"
.SH DESCRIPTION
cracklib is a library containing the
.B 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
.B password
is the potential password. The second formal argument
.B dictpath
is the full path name + filename prefix of the cracklib
dictionary database.
.B 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
.BR crack_mkdict (8)
and
.BR crack_packer (8).
On a Debian system the database is located in the directory defined by
the static constant
.B CRACKLIB_DICTPATH
and is set to @@f_pkgruntime_dict_db@@. None of the subroutines in the
cracklib libraries have this location hard-coded into their
implementations. It is generated daily with the program
@@f_pkgruntime_etc_crondaily@@.
.SH FILES
.TP
.I @@f_pkgruntime_dict_db@@.[hwm|pwd|pwi]
cracklib dictionary database files used by utilities.
.TP
.I @@f_pkgruntime_etc_crondaily@@
