One of the big wins during the Second World War was breaking the codes used by the German army for communications. They used expensive “Enigma” machines that took up entire rooms and spent huge amounts trying to break the codes.
Today I was amazed to find out you can actually get an accurate software based replica Engima Machine called Mininigma for less than the price of a coffee and it will actually decode the exact messages and codes that were used in the war.
How fast technology evolves…
