ctypes wrapper for cracklib password strength checking
Cracklib is great, and in newer packages there is a Python module available for it. However, on systems that don’t yet have it, such as CentOS 5, I’ve written a ctypes wrapper for the system cryptlib. This would also work on a system that you can’t install python-libcrypt. It does require python with ctypes available, so for CentOS 5 you have to install and use the python26 package.
