MYSTERY WIRE – The US Federal Bureau of Investigation has officially recognized the mathematician Samuel Blake from Melbourne and two other cryptologists, the American David Oranchak and the Brussels-based software programmer Jarl van Eycke, for solving a 50-year-old encrypted message sent by the nameless Serial killer named “the zodiac”.

Dr. Samuel Blake worked to decipher the message known as the “340 cipher” using a Melbourne University supercomputer called Spartan.

This is a file copy of a cryptogram sent to the San Francisco Chronicle by the Zodiac Killer in 1969. An encrypted letter sent to a San Francisco newspaper by serial killer Zodiac in 1969 has been decrypted by a team of amateurs from the United States, Australia, and Belgium, the San Francisco Chronicle reported on Friday, December 11, 2020 (San Francisco Chronicle of AP, File / San Francisco Chronicle of AP)

The cipher was posted to the San Francisco Chronicle on November 8, 1969 by a person who called himself “Zodiac”.

The Zodiac sent letters through 1974, including evidence that it was responsible for the deaths of at least five people in the San Francisco Bay Area.

“The chances of solving this after 50 years were close to zero and it’s fantastic to have a role to play in that. You know, I hope this deciphering can help you narrow down who that person is, but I think we’ll have to wait and see. Regarding the other two ciphers he sent, let’s look at these to see if there are any ways we can use the work we did on the ‘340’ cipher to make these to be resolved, but none of it is clear this phase.

The cracked cipher does not reveal a name as promised by the zodiac in separate letters.

“It was such a long shot,” said Dr. Samuel Blake. “We tried hundreds of thousands of wrong methods to solve the cipher and by chance came across a fragment of how it can be solved. With this fragment, we undone the entire solution and got the entire message out of the Zodiac. ”

Blake also said he had been working to come up with a solution to the cipher since contacting David Oranchak earlier this year.

“David Oranchak is from the United States and has been working on solving this cipher in his spare time for 15 years, which is a Herculean effort,” said Blake. “I saw some of the videos he put online to do some analysis on this cipher and I found them to be excellent so I contacted him. I think about March of this year and it was sort of sort of getting through Melbourne Covid meant playing around with it in my spare time. “

The Melbourne mathematician now hopes to crack the two remaining unsolved short ciphers: one with 13 symbols and the other with 32.
