So it would take some extra evidence to confirm any solutions to those.

“But there's too many different possible solutions that fit into those two small ciphers. Because the longer the text is, the more clues that you have, and the more weaknesses that you can exploit in order to get the underlying messages,” Oranchak says. “They're very short, which means they're very difficult for cryptographers to work on. Nor any obvious clues to two other, much shorter messages Zodiac sent after the 340 cipher. The one thing the message didn’t include? Any clues to who Zodiac might be. They’re very similar to the tone of other writings that are in his letter, and in the first cipher,” Oranchak says. A three-person team appears to have unraveled a previously unsolved cryptogram from the Zodiac Killer, who killed at least five people in Northern California in 19. “Those sounded like things that Zodiac may have written.

Blake came up with 650,000 variations of the cipher, and those were plugged into a code breaking program written by Van Eycke. That partial message included the phrases “gas chamber” and “I hope you are having lots of fun in trying to catch me.” Oranchak worked with Australian mathematician Sam Blake, and Belgian computer programmer Jarl Van Eycke. And I knew that we were on the right track.” “And so when I saw the partial message coming out of the cryptogram, while we were trying to solve it, I jumped out of my chair, and I probably scared the family dog in the process. “When you work on a problem like this for 14 years, you get used to a lot of dead ends and false starts, where you think that you might be on the right track, but you end up going nowhere,” Oranchak says.

Oranchak is a software developer and cryptography researcher in Virginia, and he first started working on the cipher in 2006. This is one of the last remaining unsolved codes that we know of, and its insane that a half century year old mystery has. One puzzle included a 340-character grid of enigmatic symbols so hopelessly scrambled and rearranged that it baffled cryptologists for decades.īut a few weeks ago, a trio of amateur codebreakers solved the so-called “340 cipher.” David Oranchak is one of them. Today we are talking about the Zodiac 340 cipher FINALLY being solved. He taunted police, journalists, and the public with menacing letters and four cryptic puzzles.

He killed at least five people, but claimed as many as 37 victims.

The first one - a long message broken into pieces sent to The Chronicle, San Francisco Examiner and Vallejo Times-Herald in 1969 - was previously cracked by a high school history teacher from Salinas, Calif., and his wife.The Zodiac Killer stalked the San Francisco Bay Area in the late 1960s. The 340 Cipher is the second Zodiac cipher to be solved.

“Due to the ongoing nature of the investigation, and out of respect for the victims and their families, we will not be providing further comment at this time,” Polan said. “The Zodiac Killer terrorized multiple communities across Northern California and even though decades have gone by, we continue to seek justice for the victims of these brutal crimes,” she said. The Zodiac Killer case remains an ongoing investigation for the FBI San Francisco division and our local law enforcement partners,” the spokeswoman, Cameron Polan, said. “The FBI is aware that a cipher attributed to the Zodiac Killer was recently solved by private citizens. No joke! This is the real deal.”Ī spokeswoman for the FBI’s San Francisco office said Oranchak’s claim was accurate. “Last weekend, a team I’m on solved the 340 and submitted it to the FBI,” code-breaking expert David Oranchak said in an email to The Chronicle Friday. Many hoped the long-standing stumper would reveal the killer’s name, but it does not.
