How quickly can a modern computer break Enigma?
How long would it take today's computers to crack the Enigma Machine? A tiny fraction of a second. The hard part of cracking the Enigma Machine is knowing when you cracked it. If you know how the Enigma Machine works, it's easy to write a function which can quickly encrypt a text using the Enigma Machine algorithm.
What might take a mathematician years to complete by hand, took the Bombe just 15 hours. (Modern computers would be able to crack the code in several minutes). Many of the weaknesses in the Enigma system came not from the apparatus itself, but from the people involved in using the code-generating machine.
It took two weeks for the team to train the machines and create the Python code, and another two weeks for the first successful attempt to decrypt a message. But in order to copy Turing's success, a successful decryption had to be done in less than 24 hours.
But the work of Bletchley Park – and Turing's role there in cracking the Enigma code – was kept secret until the 1970s, and the full story was not known until the 1990s. It has been estimated that the efforts of Turing and his fellow code-breakers shortened the war by several years.
The thing that made Enigma so hard to crack with contemporary means was that the settings changed with each keystroke. If you were to sit down at an Enigma machine right now and press the “A” key three times, you would get a different scrambled letter every time.
The 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.
They thought the Enigma Machine would allow them to pass secret war plans right under the Allies' noses. Yet, a British team of code breakers, led by the 29 year-old Alan Turing, achieved the impossible. Even if you captured a German machine you couldn't yet break the code.
Turing reportedly had an IQ of 185 but in many ways he was a typical teenager. Turing's report card from Sherborne School in Dorset, England notes his weakness in English and French studies.
It is estimated that Turing's work shortened the war by two years and saved 14 million lives.
There are known to be about 300 Enigma machines left in museums and private collections around the world, although the exact number of surviving Enigma machines is unknown, and it's suspected that there are a few more 'hiding'.
How much is an Enigma machine worth?
At the heart of all this was the Enigma machine, a cipher device that enabled Nazi forces to communicate in what was thought to be perfect secrecy. One of the rarest of Enigma machines, with less than 100 thought to exist, has just been sold in an online auction by Christie's for $440,000 (£347,250).
Many Enigma machines that did survive were then demolished by Allied forces at the war's end, per orders from U.K. Prime Minister Sir Winston Churchill. Now, there are only about 250 WWII-era Enigma machines left.
As early as 1943 Turing's machines were cracking a staggering total of 84,000 Enigma messages each month - two messages every minute. Turing personally broke the form of Enigma that was used by the U-boats preying on the North Atlantic merchant convoys. It was a crucial contribution.
A major flaw with the Enigma code was that a letter could never be encoded as itself. In other words, an “M” would never be encoded as an “M.” This was a huge flaw in the Enigma code because it gave codebreakers a piece of information they could use to decrypt messages.

Well, the Enigma wasn't perfect, and contained one flaw which was exploited by Turing in order to solve the code. He did this by building a giant machine called the Bombe, which essentially worked backwards through the Enigma Machine coding process in order to determine how the machine was set each day.
Road Trip 2011: Code breakers led by Alan Turing were able to beat the Germans at their cipher games, and in the process shorten the war by as much as two years. At Bletchley Park, all the work took place in secret, where it stayed for decades.
It is estimated that the intelligence produced at Bletchley Park shortened the war by two to four years, and Turing played a central role in this.
Turing was a brilliant mathematician, before he'd even earned a Master's Degree he wrote probably the second-most-important academic paper of the 20th century – second only to Albert Einstein's paper on General Relativity.
Marilyn Vos Savant (IQ - 228)
Louis, Missouri in 1946 when Marilyn Vos Savant was 10 years old, in an adult level Stanford-Binet Test found out that her IQ is 228. Due to this record-breaking result, her name was recorded in the Guinness Book of World Records.
What is the highest IQ ever recorded?
Marilyn Vos Savant (IQ score of 228)
This American entered the Guinness Book of World Records as the person with the highest IQ back in 1986.
Albert Einstein is believed to have had the same IQ as Professor Stephen Hawking, 160.
Some military historians estimate Turing's genius saved as many as two million lives.
With only 318 Enigma machines known to exist today, the experience offered a once in a lifetime opportunity for Sven Mayer, postdoctoral researcher; Yang Zhang, doctoral student, and Karan Ahuja, doctoral student, all of the Human-Computer Interaction Institute.
Similar machines were first made in the early 20th century, and the first 'Enigma' was invented by German engineer Arthur Scherbius in 1918, who sought to sell it for commercial, rather than military, purposes.
Today an original Enigma machine has gone on display at The Alan Turing Institute.
Since in the new enigma machine, one extra rotor had been added, which had 26 wired discs. So total possible combinations are 264. To increase the irregularity of the rotational behavior of the rotors, the German Navy used a second notch to some rings in order.
While there, Turing built a device known as the Bombe. This machine was able to use logic to decipher the encrypted messages produced by the Enigma. However, it was human understanding that enabled the real breakthroughs. The Bletchley Park team made educated guesses at certain words the message would contain.
The most sophisticated Enigma machines had an 84 bit key (that means in the order of 2^84 possible keys, the actual theoretical number is 31,291,969,749,695,380,357,632,000, which is a big number).
Enigma got it wrong because: Security of Enigma depended on wiring of rotors, Wiring was part of algorithm and not part of key, and. Wiring never changed from 1920s until 1945.
What country cracked the Enigma code?
After the war, the achievements of Rejewski and the Cypher Bureau were all but forgotten as Poland went into a communist deep freeze for nearly fifty years. To the outside world, it was Turing that had cracked the Enigma and shortened the war.
Selma is 100% historically accurate but Imitation Game just 41.4%, says study. The liberties taken by films purporting to retell real-life stories vary enormously, a new study has found.
British sailors from HMS Bulldog captured the first naval Enigma machine from U-110 in the North Atlantic in May 1941, months before the United States entered the war and three years before the US Navy captured U-505 and its Enigma machine.

An iconic artefact from the Second World War has sold at auction for nearly half a million dollars. The Enigma M4 machine was sold for $440,000 (£347,250) to an anonymous buyer last week, with Christie's handling the sale.
The Royal Navy captured German U-boat U-110 on May 9, 1941 in the North Atlantic, recovering an Enigma machine, its cipher keys, and code books that allowed codebreakers to read German signal traffic during World War II.
