crack_mkdict, crack_packer, crack_unpacker - cracklib dictionary
crack_mkdict 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
If you supply massive amounts of text to crack_mkdict 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/crack_mkdict 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_mkdict has a hook for this.
crack_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 and crack_unpacker,
crack_testlib(8), crack_testnum(8), and crack_teststr(8) utilities
understand. The number of words read and written are printed on
crack_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_mkdict(8) and crack_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.
