Z-340 Solved.

A coded message sent by a brutal serial killer who has never been caught has been cracked more than 51 years after it was sent.

https://arstechnica.com/information-technology/2020/12/zodiac-killer-cipher-is-cracked-after-eluding-sleuths-for-51-years/

The male suspect, known as the Zodiac Killer, killed at least five people and attempted to kill at least two more in Northern California in 1968 and 1969. In the first three attacks, he targeted couples. The first two murder victims were high school students who were parked in a car on their first date. In attacks on the other two couples, he managed to kill the women, but the men survived. A male San Francisco cab driver was the last known victim.

During the murder spree, the Zodiac Killer sent media outlets a series of letters taking credit for the slayings. To prove the authenticity of the claims, the letters included unreleased details and evidence from the crime scenes.

In August 1969, following the murders of three of the five known victims, the Zodiac Killer sent three almost identical letters to three Bay Area newspapers. Each letter also included one-third of a 408-symbol cryptogram that the suspect said would reveal his identity. The killer demanded the papers publish the letters in full or he would kill again.

A week after the letters were sent, a couple in Salinas, California, cracked the cipher. The Zodiac Killer, the plaintext revealed, said he was collecting slaves for the afterlife and that he wouldn’t disclose his identity because doing so would interfere with those plans.

In November 1969, after killing the remaining two known victims, the Zodiac Killer sent a letter to the San Francisco Chronicle that included a new puzzle. The cryptogram was known as the Z-340, or simply the 340, because it contained 340 characters in it

In a statement, the FBI have confirmed that a new decoding of the cipher by three private codebreakers appears to be correct.

Dave Oranchak a 46 year-old software developer in Viginia collaborated with Sam Blake an applied mathematician who lives in Australia, and Jarle Van Eycke who works as a warehouse operator in Belgium but has written code-breaking software including AZdecrypt which was the tool used to break this transposition cipher.

Their final readout is below:
I HOPE YOU ARE HAVING LOTS OF FUN IN TRYING TO CATCH ME THAT WASN’T ME ON THE TV SHOW WHICH BRINGS UP A POINT ABOUT ME I AM NOT AFRAID OF THE GAS CHAMBER BECAUSE IT WILL SEND ME TO PARADICE ALL THE SOONER BECAUSE I NOW HAVE ENOUGH SLAVES TO WORK FOR ME WHERE EVERYONE ELSE HAS NOTHING WHEN THEY REACH PARADICE SO THEY ARE AFRAID OF DEATH I AM NOT AFRAID BECAUSE I KNOW THAT MY NEW LIFE WILL BE AN EASY ONE IN PARADICE DEATH

I don't know if you've seen the film of the Zodiac killer. It's pretty good.

https://www.imdb.com/title/tt0443706/?ref_=nv_sr_srsg_0

It's true they never caught the guy but they'd narrowed it down to someone who then died. After he'd gone everything stopped.

It's a tribute to the film that, although we know there's no arrest, it still keeps you gripped to the end.

This is like the suicide bomber thing, isn't it?

So that's it, it's all down to the Fear Of Death! Convince them they'll go to a paradise of free sex and Netflix after they cop it and they'll do whatever you say.

The politicians don't do death, of course, so they'll offer you paradise now... but only after you've got them elected.
