Distributed.net is a volunteer computing effort that is attempting to solve large scale problems using otherwise idle CPU or GPU time. It is governed by Distributed Computing Technologies, Incorporated (DCTI), a non-profit organization under U.S. tax code 501(c)(3).

Distributed.net is working on RC5-72 (breaking RC5 with a 72-bit key).[1] The RC5-72 project is on pace to exhaust the keyspace in just over 40 years as of February 2024,[2] although the project will end whenever the required key is found. RC5 has eight unsolved challenges from RSA Security, although in May 2007, RSA Security announced[3] that they would no longer be providing prize money for a correct key to any of their secret key challenges. distributed.net has decided to sponsor the original prize offer for finding the key as a result.[4]

In 2001, distributed.net was estimated to have a throughput of over 30 TFLOPS.[5] As of August 2019, the throughput was estimated to be the same as a Cray XC40, as used in the Lonestar 5 supercomputer,[6] or around 1.25 petaFLOPs.[7]
