-cracking and frustrate fast hardware implementation.  The computation cost of
-the algorithm is parametrised, so it can be increased as computers get faster.
-The intent is to make a compromise of a password database less likely to
-result in an attacker gaining knowledge of the plaintext passwords (e.g. using
-John the Ripper).")
