Download Source:
http://prdownloads.sourceforge.net/cracklib/cracklib-2.8.22.tar.gz
http://downloads.sourceforge.net/cracklib/cracklib-words-20080507.gz (Recommended word list for English-speaking countries)
Download Optional Patch:
http://svn.cross-lfs.org/svn/repos/patches/cracklib/cracklib-2.8.22-heimdal-2.patch (Required patch to create a library used with the Heimdal Kerberos 5 package)

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-2.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-2.8.0.so /lib &&
mv -v /usr/lib/libcrack-2.8.0.so /lib &&
ln -svf ../../lib/libcrack-2.8.0.so /usr/lib/libcrack.so

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
echo $(hostname) >>/usr/share/dict/cracklib-extra-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-2.patch

32Bit

Configure and compile the package: 

CC="gcc ${BUILD32}" USE_ARCH=32 ./configure --prefix=/usr -with-default-dict=/lib/cracklib/pw_dict &&
make

Install the package: 

make install &&
mv -v /usr/lib/libcrack-2.8.0.so /lib &&
mv -v /usr/lib/libcrack-2.8.0.so /lib &&
ln -svf ../../lib/libcrack-2.8.0.so /usr/lib/libcrack.so

N32

Configure and compile the package: 

CC="gcc ${BUILDN32}" USE_ARCH=n32 ./configure --prefix=/usr \
  --libdir=/usr/lib32 -with-default-dict=/lib/cracklib/pw_dict &&
make

Install the package: 

make install &&
mv -v /usr/lib32/libcrack-2.8.0.so /lib32 &&
mv -v /usr/lib32/libcrack-2.8.0.so /lib32 &&
ln -svf ../../lib32/libcrack-2.8.0.so /usr/lib32/libcrack.so

64Bit

Configure and compile the package: 

CC="gcc ${BUILD64}" USE_ARCH=64 ./configure --prefix=/usr \
  --libdir=/usr/lib64 -with-default-dict=/lib/cracklib/pw_dict &&
make

Install the package: 

make install &&
mv -v /usr/lib64/libcrack-2.8.0.so /lib64 &&
mv -v /usr/lib64/libcrack-2.8.0.so /lib64 &&
ln -svf ../../lib64/libcrack-2.8.0.so /usr/lib64/libcrack.so

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

Contents
