Free Rainbow is using the BOINC client to distribute the workload to multiple clients
By downloading and installing this software, the machine will contribute to the generation of more tables, using the idle CPU power.
All tables generated are freely available for download from the mirrors (See the tables page)

BOINC Client:

BOINC (Windows x86)
BOINC (Windows x64 and Linux)

To contribute to the project, download the BOINC client and point it to the project url
You need to create a seperate account for BOINC. If you use the same email for your account at and, you will be able to view statistics about your progress.

How it works:
DistrRTgen is based on Zhu Shuanglei's Project Rainbow Crack.
The client connects to a server, which delegates work between all clients and designates you part of a table to generate. Your computer generates it's designated 'part', and uploads it to the server, upon which you are designated the next part.
