I can just imagine what a one arduino could have done ........

"The Imitation Game" (2014) is the fascinating story of the development of this machine by its inventor, Alan Turing.

Umm - pretty much concieved by the Polish Cryptanalysts Marian Rejewski et al. already in 1932,
though Dennison, Knox and Turing et al jumped on the bandwagon in 1939,
when Poland "exported" "the Bombes", people and info to France.
This stuff and staff then got over the Channel when France fell.

Just my shorthanded 2 cents.

"The Code Book" by Simon Singh is still worth a read, though ca 20 years old by now
(and the cryptanalytic competition within is already solved by a few compatriots of mine)

Another (Swedish) cryptanalytical feat during the war; The Siemens & Halske T52:

Bletchley Park weren't as successful as the Swedes with the so-called "Sturgeon":

Uh, shows my ignorance (again!).....and to think that Hollywood didn't tell the whole story. Thanks for the enlightenment and links to this history!

...and to think that Hollywood didn't tell the whole story.

They rarely do in Hollywood - they're NOT investigative reporters.

For instance: "U-571" claimed the Yanks first got hold of the Naval Enigma, too...
(Narrowly staying on-topic...)

(It also showed a WWII naval yard worker with a present-day yellow DeWalt grinder,
and after firing a torpedo, one of the crew uses a Swatch (funded in 1983) chronograph,
just to name two "mishaps" in the making of that movie.
