Free Rainbow Tables

The goal of is to prove the insecurity of using simple hash routines to protect valuable passwords, and force developers to use more secure methods.
By distributing the generation of rainbow chains, we can generate HUGE rainbow tables that are able to crack longer passwords than ever seen before.
Furthermore, we are also improving the rainbow table technology, making them even smaller and faster than rainbow tables found elsewhere, and the best thing is, those tables are freely available!
By installing and running the BOINC client available from our download page, you can help us to speed up the generation even more
For detailed information about how DistrRTgen (Distributed Rainbow Table Generator) works, see the download page

Getting Started is Simple:

Download the client from our downloads page and follow the instructions found there
