www.britannica.com › topic › Enigma-German-code-deviceThe Enigma code was first broken by the Poles, under the leadership of mathematician Marian Rejewski, in the early 1930s. In 1939, with the growing likelihood of a German invasion, the Poles turned their information over to the British, who set up a secret code-breaking group known as Ultra, under mathematician Alan M. Turing. Because the Germans shared their encryption device with the Japanese, Ultra also contributed to Allied victories in the Pacific.

During World War II, the Germans used ENIGMA, a cipher machine, to develop nearly unbreakable codes for sending messages. ENIGMA’s settings offered approx. 158,000,000,000,000,000,000 possible solutions, yet the Allies were eventually able to crack its code. The machine was developed by the Dutch to communicate banking secrets.
Cryptanalysis of the Enigma - Wikipedia
https://en.wikipedia.org/wiki/Cryptanalysis_of_the_EnigmaAs the likelihood of war increased in 1939, Britain and France pledged support for Poland in the event of action that threatened its independence. In April, Germany withdrew from the German–Polish Non-Aggression Pact of January 1934. The Polish General Staff, realizing what was likely to happen, decided to share their work on Enigma decryption with their western allies. Marian Rejew…
The Enigma of Alan Turing - CIA - Central Intelligence Agency
www.cia.gov › stories › storyApr 10, 2015 · Poland was actually the first to realize that the solution to breaking ENIGMA would most likely be discovered by a mathematician. Polish cryptanalysts as early as 1932 could decode German ciphers and, by 1939, they were able to successfully decipher messages written with an earlier version of ENIGMA using a replica machine like “the bombe” that could emulate the way ENIGMA worked.
