the enigma code was cracked, how long was it possible for the allides to read all messages sent by the germans

The Enigma code was effectively cracked by Allied cryptanalysts, most notably at Bletchley Park in the United Kingdom, during World War II. The first significant breakthroughs began around 1939, with the most notable progress made by mathematician Alan Turing and his team. By 1941, the Allies had developed methods to regularly decrypt Enigma messages, particularly those from the German military. However, it's important to note that the ability to read all Enigma-encrypted messages was not continuous; it depended on several factors, including the specific Enigma machine settings and the time period of the war. The Allies could read a significant portion of the messages but did not decrypt all messages all the time due to changes in settings and the introduction of newer versions of the Enigma machine. In summary, the Allies were able to read a substantial number of messages sent by the Germans starting from around 1941, and this capability continued throughout much of the war until the German use of the Enigma was largely replaced or compromised by other methods. The decryption efforts remained a critical advantage for the Allies and contributed significantly to the war effort.
