Who could read the enigma?

The Enigma machine was primarily used by the German military during World War II, and its codes were intended to be read only by those who had access to the machine and its settings, such as German cryptographers and military personnel. However, Allied codebreakers, particularly those at Bletchley Park in the UK, eventually succeeded in breaking the Enigma codes, notably through the efforts of figures like Alan Turing and his colleagues. Their work enabled the Allies to intercept and decipher German communications, significantly impacting the war's outcome.
