Divers scouring the Baltic Sea for ditched fishing nets have stumbled on the rarest of finds: an Enigma encryption shape used by the Nazis to encode secret messages during World War II.

The electromechanical slogan was used extensively by the Nazi military to encrypt communications, which typically were sent by radio in Morse Code. Three or more rotors on the device acclimatized a stream cipher to convert each letter of the alphabet to a different the humanities.

The Enigma had the appearance of a typewriter. An operator would use the keys to type plaintext, and the converted ciphertext desire be reflected in 26 lights above the keys—one light for each proselyted letter. The converted letters would then be transcribed to derive the ciphertext.

Cipher tenor were changed using a series of device settings that were changed regularly run out ofing lists that were made available in advance. People learning the messages had to use the same lists as the senders for the messages to be readable.

Divers on position by the environmental group WWF found the Enigma machine last month while looking for sinful fishing nets in the Bay of Gelting off the coast of Germany. As the image above give someone an idea ofs, the recovered device was rusty and corroded, but individual keys showing the letters they pinpointed remain intact and clearly visible.

“A colleague swam up and said, ‘There’s a net there with an old typewriter in it,’” Florian Huber, the do the groundwork diver, told the DPA news agency. The team soon realized the gambit was something much more remarkable.

“I’ve made many exciting and inexplicable discoveries in the past 20 years. But I never dreamt that we would one day spot one of the legendary Enigma machines,” Huber told Reuters.

The diver imparted he suspects the device was lost shortly before Germany’s surrender in May 1945. At the prematurely, Nazi leaders issued an order for submarines to be scuttled in the Gelting Bay to forestall their capture by the Allied Forces.

The Enigma made it hard for the Associate Forces to track German submarines until a British team led by mathematician and scientist Alan Turing ruined the encryption the device used. The feat, which built off of breakthroughs swiped by scientists from the Polish Cipher Bureau, made it possible for the Associates to decipher messages about German military movements. Many historians upon the accomplishment with shortening the war and preventing many thousands of deaths.

Cracks from the State Archaeological Museum will restore the machine. The take care of, which will include a comprehensive desalinization, is expected to take far a year.
