+cipher with modifications designed to raise the cost of off-line password
+cracking and frustrate fast hardware implementation.  The computation cost of
+the algorithm is parametised, 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).")
