Crib Room
A ‘crib’ was information in a message that gave a clue about how it might have been enciphered. It could be something like a routine phrase such as ‘Nothing tp report’. Staff looked for likely phrases and passed ‘menus’ to Bombe operators who would set the machines to search for message that might contain that crib.

Netz Room
To test out possible settings for the day’s Enigma keys, large pieces of paper, known as Netz sheets, were punched through with holes according to the keys sent in various messages. The sheets were then stacked over a light. If the light shone up one hole through the whole stack it was called a ‘drop’ indicating settings that might be correct.

Hut 3 Administration and Typing room
Staff in the Administration and Typing Room typed up messages based on the deciphered messages. They sent them to MI6 and to the few other people authorised to receive them. To keep secret the fact that Enigma had been broken, these reports were made to appear as if they had been sent by a fictitious MI6 spy codenamed Boniface.
TO GENERATE AN ENCRYPTION KEY : 2 CASES
FIRST CASE :
The key can be stored in your brain. In this case a complex key should be used. This could be a precise sentence like "Blue is my favorite color20180416" which is easy to remember.
You store it in a file, whatever its extension.
SECOND CASE :
You can generate a precise size random key via a seed you choose : a key is unique to its seed
* You specify the size of the key (number of characters) ;
* You choose the seed ;
* You generate file containing the key ;
* You use the key file to cypher
* You save the key file in a secured place. Losing the key file will reduce your chance to uncypher your file to zero

Alan Turing’s office
Here at his desk in Hut 8, Turing took the lead on breaking naval Enigma ciphers - something few thought could ever be done. His mathematical skills also enabled him to break other ciphers, including the complex Lorenz cipher where he used a method that became known as Turingery. Together with he’s fellow Codebreaker Gordon Welchjman, he developed the Bombe machine to help speed up the codebreaking process.

Secure File Transport consists of TLS and AES 256 encryption where the critical data is not only safeguarded, but also satisfies the required compliances. A Cloud Maven Inc. product powered by BotDoc, sends and receives such data into and from Salesforce. Large files of different formats can be sent and received from any Salesforce standard or custom object. No requirement of passwords or pins makes it simple and safe to perform the documents transfer. For more information visit: info@cloudmaveninc.com

The Watch
Work at BP went on around the clock. In this room there were four Watchkeepers on each shift, led by Watch No.!. Most were civilian experts in German, able to fill any gaps in the deciphered messages before translating them. As they had no military experience, special Military Advisers helped compile the final reports.

Advisers Room
The Air Advisers and Military Advisers who worked with each Watch were usually RAF and army officers. their job was to advise the civilian Watchkeepers on military and technical details. They made sure Hut 3 reports used the correct terminology so that the senior commanders who received them would trust their content.

Decoding Room
Once the day’s Enigmas settings, or keys, had been broken in the Machine Room, intercepted messages were typed into Typex machines adjusted to these settings. The deciphered messages, usually in German, then emerged from the machine. The noise from the Typex machines when the ciphers were being decoded could be heard throughout the hut.
1947 Sunbeam Talbot
2 litre Sports Saloon converted to a Tourer
Shipped to Simpsons of Madras when new on 12th September 1947, this car was oringally light green, which is still visible in some places. Following its return to the UK the car was generously donated to Bletchley Park Trust by Mick Jagger after starring in the film Enigma (2001) which was produced by Jagger’s film company.
Loosely based on real events, the film follows the story of cryptanalysts at Bletchley Park facing their worst nightmare: Nazi U-boats have unexpectedly changed their Enigma cipher and a merchant shipping convoy with 10,000 people on board is in peril.
Jagger required a period sports car for the starring role, which had a large enough boot into which a secret compartment could be built to house the Enigma machine. A Sunbeam Talbot 2 Litre Tourer would have been ideal, but they were rare in 2001, therefore this Saloon was acquired. The while of the body from the scuttle backwards had been removed and replaced by a custom 4 seater Tourer body and windscreen with the required compartment behind the rear seats. Notice the blackout headlights.
