" The cipher goes like this: - Playfair using "zodiac" as the key - Vigenere using "zodiac" as the key A substitution alone is not enough to prove a solution, and due to the complexity and knowledge Three men received recognition in December 2020 for cracking the Zodiac Killer's 340-character cipher (Z340) – but they want to share credit with the community of sleuths who helped with the 51-year code breaking effort. But this challenge on October 22nd 1969 was laid down An individual who helpfully provides a valid key to the 408 cipher on August 10th 1969, while subsequently offering an array of unhelpful cryptic nonsense just two months later, appears to invalidate the original communication as a concerned citizen.
