Check passwords using libcrack2
create-cracklib-dict wordlist ...
create-cracklib-dict takes one or more word list files as arguments and converts them into cracklib dictionaries for use by password checking programs. The results are placed in the default compiled-in dictionary location.
If you wish to store the dictionary in a different location, use the cracklib-format and cracklib-packer commands directly.
