Introduction to Cracklib

Cracklib is used to enforce strong passwords. It uses its dictionary of words to verify that passwords are difficult to crack.

Project Homepage: http://sourceforge.net/projects/cracklib/

Dependencies

Optional

Non-Multilib

If desired, apply the Heimdal patch (note that with this patch the original library is not affected; this patch only creates an additional library used by the Heimdal password-checking routines): 

patch -Np1 -i ../cracklib-2.8.22-heimdal-1.patch

Configure and compile the package: 

./configure --prefix=/usr -with-default-dict=/lib/cracklib/pw_dict &&
make

Install the package: 

make install &&
mv -v /usr/lib/libcrack.so.2.8.1 /lib &&
ln -svf ../../lib/libcrack.so.2.8.1 /usr/lib/libcrack.so &&
ldconfig

Install the dictionary: 

install -v -m644 -D ../cracklib-words-20080507.gz /usr/share/dict/cracklib-words.gz
gunzip -f /usr/share/dict/cracklib-words.gz
ln -svf cracklib-words /usr/share/dict/words
install -v -m755 -d /lib/cracklib
create-cracklib-dict /usr/share/dict/cracklib-words

Multilib

If desired, apply the Heimdal patch (note that with this patch the original library is not affected; this patch only creates an additional library used by the Heimdal password-checking routines): 

patch -Np1 -i ../cracklib-2.8.22-heimdal-1.patch
