Lightbulb After 51 years, the Zodiac Killer's cipher has been solved by amateur codebreakers

Quote:
More than 50 years after the so-called Zodiac Killer first began terrorizing the streets of Northern California, a code-breaking team is believed to have finally cracked one of the killer's mysterious coded messages sent to the San Francisco Chronicle in 1969.

Dubbed the "340 cipher," the message was unraveled by a trio of code breakers -- David Oranchak, a software developer in Virginia, Jarl Van Eycke, a Belgian computer programmer, and Sam Blake, an Australian mathematician.
Decoding the cipher revealed the following message. It was sent in all capital letters without punctuation and included the misspelling of paradise:
Quote:
"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."

Very interesting. The first two murders attributed to the Zodiac killer on December 20, 1968, were just over a mile away from my home.

Thanks for sharing that. Nice materials to read and google. A bit disappointing that the Urbanist article doesn't mention the cypher I spent the most time in my life, haha, the Problem 9 of the Haselbauer-Dickheiser test. Up to my knowledge, that's the only problem in the test nobody solved, ever. There is only one guy in the world who solved 23 of the 25, during the test was active. I solved 18 of them, and know the answer to 21 (by sharing with other people later). I spent about 3 months on this test (including the encryption, but the most time was spent for the Furbles problem, to which I still don't know the correct answer). All in all, 24 of them were solved by one or the other person in the world, and the only one eluding the "IQ geeks" is the encryption.

(edit: offtopic: I may have said that here around, Problem 2 in this test is by far the BEST puzzle I ever solved in my life, and I would still pay money for a correct solution to the Furbles problem)

I was present at a Eurocrypt meeting where Jim Gillogly revealed his solution of one of the Kryptos ciphers.

He and I have both worked on the d'Agapayeff cipher without success. (We each have copies of the book in which it appeared).

One we did solve for the first time --- by "we" I mean Jim, my wife, his wife and me contributing equally --- is the following pangram:

ABCD EFGHIJ K.L.M. NOPQ, RST UV W.X.Y'Z

It was allegedly sent by an officer in Napoleon's Egyptian campaign after a local guy had shown great bravery in a covert action which had required him to remove almost all his clothing to get through the defenses. and had become very chilled in the cold desert night.

Our solution is available on the net but I urge you to try to solve it for yourself.

Probably not found, all of them looks like gibberish, but here it is:
using a wordlist of size=9027 [basically a 10k list, but deleted all words with length<4 that was not in a 4k list]. All solutions up to 15 words. Assuming ofcourse the https://en.wikipedia.org/wiki/ADFGVX_cipher and key length=3 .
