Description:
CrackLib is a library containing a C function (well, lots of
functions really, but you only need to use one of them) 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 the source.
CrackLib is an offshoot of the the version 5 "Crack" software,
and contains a considerable number of ideas nicked from the new
software. At the time of writing, Crack 5 is incomplete (still
awaiting purchase of my home box) - but I though I could share
this with you.
NOTE THIS WELL: CrackLib is NOT a replacement "passwd" program.
CrackLib is a LIBRARY. CrackLib is what trendy marketdroid types
would probably call an "enabler".
The idea is that you wire it into your _own_ "passwd" program (if
you have source); alternatively, you wire it into something like
"shadow" from off of the net. You can use it almost _everywhere_.

Advertised architectures:
CrackLib has been tested mostly on Suns. If you can point me at
ways round portability problems (eg: static linking, other
libraries, etc) I'd be most grateful.
