This is a portion of Openwall's collection of password recovery tools,
as well as some other related tools.  These and many other tools - with
descriptions and website links - are available at:

http://www.openwall.com/passwords/

Some of these tools are completely free (some are also Open Source).
Some others are shareware ("try before you buy").  While Openwall's own
activities are focused on free and Open Source software, we're offering
these shareware tools from our partners in order to help fund our
primary activities.  When you purchase these tools via links from the
builds of the tools found in this collection or via the Openwall website
at the URL above, a (large) percentage of the amount you pay is directed
towards Openwall's free software development and maintenance.
