Editing Cryptanalysis of the Enigma (section)

==After World War II==
Modern computers can be used to solve Enigma, using a variety of techniques.<ref>{{Harvnb|Sullivan|Weierud|2005}}</ref> There have been projects to decrypt some remaining messages using [[distributed computing]].<ref>{{citation |title=M4 Message Breaking Project |url=https://www.bytereef.org/m4_project.html |access-date=16 October 2008}}</ref>

On 8 May 2020, to mark the 75th anniversary of [[Victory in Europe Day|VE Day]], [[GCHQ]] released the last Enigma message to be decrypted by codebreakers at Bletchley Park. The message was sent at 07:35 on 7 May 1945 by a German radio operator in [[Cuxhaven]] and read: "British troops entered Cuxhaven at 14:00 on 6 May 1945 – all radio broadcast will cease with immediate effect – I wish you all again the best of luck". It was immediately followed by another message: "Closing down forever – all the best – goodbye".<ref>{{citation |title=VE Day: Last Nazi message intercepted by Bletchley Park revealed |date=2020-05-08 |publisher=[[BBC]] |url=https://www.bbc.com/news/uk-52583322}}</ref>

The break into Enigma had been kept a secret until 1974. The machines were used well into the 1960s in Switzerland, Norway ([[Norenigma]]), and in some British colonies.
