22-Year Old Spaniard Cracks Previously Unsolved WW2 Message Code

BARCELONA, Spain, August 27, 2015 /PRNewswire/ --

- It is believed that the message dates from the Normandy D-Day landings.   
- Dídac Sánchez is offering EUR25,000 to anyone who can figure out how the code works.  

Young Spanish entrepreneur Dídac Sánchez announced today that he had cracked the encryption scheme used in the last undeciphered WW2 message and challenged anyone to figure out the code's structure in return for a EUR25,000 reward. GCHQ, the British intelligence organisation, confirmed that this code, found on the leg of a homing pigeon, had yet to be deciphered.

After three years of research and a EUR1.5m investment Dídac Sánchez has developed new security software called 4YEO (ForYourEyesOnly), based on the structure of the previously undeciphered encrypted code. This software will be marketed in late 2016 and will allow any text, document, WhatsApp, Messenger, SMS or Skype conversation, or telegram to be encrypted, as well as telephone calls.

To demonstrate the inviolability of the 4YEO system, based on this code used by the British and the French Resistance, Dídac Sánchez has published a message with an identical structure on his website (http://www.4yeosoftware.com), where he is offering EUR25,000 to anyone who can successfully decipher it. The competition rules have been deposited with the Aloy Martorell notarial office in Barcelona. The time period for cracking the code runs from 1 September to 31 December 2015.

"To date, the intelligence services have been unable to crack this message's code because they were missing the code word, the code book and the encryption method used. After successfully deciphering the method used I have developed a piece of software that I believe is one of the most secure in the world, because I have adapted the British code to the data security required today by new technologies," explained Dídac Sánchez.


In 1982 David Martin, a resident of Surrey (UK), refurbished his home and found the skeleton of homing pigeon 40TW194 in his chimney. It had a red capsule attached to its leg. The tube contained an encoded message written on thin cigarette paper. It has 27 codes, each comprised of five letters or numbers, and the signature of a presumed Sergeant W. Stot. It was addressed to X02 (presumably Bomber Command), and it is believed to date from the time of the Normandy D-Day landings (6 June 1944).

On that day, Winston Churchill decreed absolute radio silence and homing pigeons were used for many of the messages sent to the Bletchley Park intelligence centre (the predecessor of today's GCHQ) where the mathematician Alan Turing was working. Turing was the main decryption agent for the Nazi codes generated by the 'Enigma' machine. This base was located only five miles (eight km) from Martin's house.

About Dídac Sánchez  

Dídac Sánchez has very humble origins. He was born in the Raval district of Barcelona into a dysfunctional family. He spent four years in local authority care, together with his two sisters, after the Regional Government removed all the children from their parents' custody.

In this complex social framework, without accredited studies, and solely trusting in his entrepreneurial tenacity, Dídac Sánchez left care aged 18 and started working as a messenger and doing photocopying at an insurance broker, repairing computers and creating web pages.

In just four years Dídac Sánchez (http://www.didacsanchez.com) has created the Legisdalia group (http://www.legisdalia.com), which operates in five countries. In 2014 its turnover was EUR32m. The 2015 forecast is EUR50m. His entrepreneurial activities encompass five business areas: Health, the Internet, Law, Communication and Music. 4YEO is a new cryptanalysis business for monitoring, intercepting and decoding data in the business environment and between individuals.
