libcrack2 2.8.20-0ubuntu1 (amd64 binary) in ubuntu raring

 Shared library for cracklib2 which contains a C function 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 source. cracklib2 is NOT a replacement passwd
 program. cracklib2 is a LIBRARY.
