-------- DESCRIPTION
---------------------------------------------------------

This module enables a more secure password storage for Drupal 6 by
back-porting the code used in Drupal 7 core.

A vulnerability in this API allows an attacker to send specially crafted
requests resulting in CPU and memory exhaustion. This may lead to the site
becoming unavailable or unresponsive (denial of service).

This vulnerability can be exploited by anonymous users
