Treasured few persons are allowed into this legendary assortment of paperwork and letters spanning 12 centuries. But even in that context, Megyesi’s 2012 go to was unusually intriguing. She was right here to see texts so secret that no residing individual, not even the pope, may let you know what they comprise.
Megyesi, a linguist primarily based at Uppsala College in Sweden on the time, had travelled to the Vatican to pore over a tranche of papers written in elaborate ciphers – the key codes utilized by spymasters and others desperate to ship non-public messages. An knowledgeable in cracking historic codes, she had been invited after breaking the infamous Copiale cipher.
Megyesi had the chance to make use of the Vatican’s encrypted papers for a challenge with an audacious purpose: to totally automate the method of decrypting historic ciphers in order that many 1000’s of in any other case inaccessible letters may lastly communicate to us from down the centuries. “The dream is to have the ability to level your telephone digital camera at a cipher and skim it instantly,” she says.
Within the decade since, Megyesi and her colleagues have developed software program that expedites their painstaking cryptanalysis – and researchers related to the challenge have notched some exceptional successes. These embrace the latest decryption of a very fiendish code employed by a Seventeenth-century French nobleman and, most sensationally, the cipher encrypting letters written by …
