'''Enigma@Home''' was a [[BOINC]] volunteer computing project that attacked genuine, unsolved [[wikipedia:Enigma-M4|Enigma M4]] cipher messages from the Second World War using a combination of brute force search and hill climbing cryptanalysis. The project was a BOINC "wrapper" around Stefan Krah's '''M4 Project''' (also called the '''M4 Message Breaking Project'''), which was launched independently in January 2006 before being ported to the BOINC platform to draw on a much larger pool of volunteered computer time.<ref name="bytereef-m4">{{Cite web |title=M4 Message Breaking Project |url=https://www.bytereef.org/m4_project.html |website=bytereef.org |authors=Stefan Krah |accessdate=2026-07-15}}</ref><ref name="networkworld">{{Cite web |title=Still trying to crack Nazi Enigma messages |url=https://www.networkworld.com/article/2247101/still-trying-to-crack-nazi-enigma-messages.html |website=Network World |date=2009-08-31 |accessdate=2026-07-15}}</ref> Over the project's lifetime, volunteers helped recover the plaintext of several authentic [[wikipedia:Kriegsmarine|Kriegsmarine]] radio messages that had defeated Allied codebreakers at [[wikipedia:Bletchley Park|Bletchley Park]] during the war and had remained unbroken ever since.
