Welcome to the Zodiac Ciphers wiki
This wiki is an attempt to gather all useful factual and verifiable information pertaining to the ciphers associated with the "Zodiac Killer". It is also a place to post results of experimental analysis of the ciphers.
There is so much information on these ciphers, but it is very hard to find in one place. This wiki tries to correct this problem by curating factual tidbits, experimental results, and analysis in a single location.
Site contents:
- Solved 408-character cipher
- Solved 340-character cipher
- Unsolved 13-character "My name is" cipher
- Unsolved 32-character "map code" cipher
- Webtoy's transcription scheme - ASCII representations of the ciphertext on this wiki use the Webtoy's ASCII transcriptions of the cipher.
- Software Tools
- Word counts from the Zodiac Killer's correspondences
- Research papers - Academic papers related to Zodiac ciphers in particular, and cryptography in general
- Cipher comparisons - Tabulation of measurements performed on an assortment of ciphers. Includes various test ciphers, and famous unsolved ciphers.
- Timeline - A collection of events associated with the crimes of the Zodiac killer
- Collection of test ciphers - A collection of ciphers, many with known solutions, organized by how much they resemble the unsolved 340-character cipher.
Discredited or inconclusive solution attempts
- Daryll Lathers' 340 solution: Overuse of anagrams, and polyalphabetic assignments of plaintext letters to cipher symbols:
- Traveller1st's partial 340 solution: A demonstration of how partial solutions can be created which contain Zodiac-related words and phrases:
- Özcan Türkmen's solution: Overuse of anagrams, and many other subjective interpretations of plaintext fragments:
- Partial solution by Jonas: A solution that contains a name and a few legible words, but much gibberish.
- Thomas Dougherty's code theory: A production of plaintext letters arbitrarily expanded into full words.
- Lyndon Lafferty (13 cipher): A combination of approaches that produces ambiguous solutions.
- Corey Starliper (340 cipher): An arbitrary decryption system that permits the insertion of a predetermined message.
- AK Wilks / Zander Kite (32, 408, and 340 ciphers): These decryption systems permit many arbitrary solutions due to vast spaces of possible selections.

- Analysis and discussion
- Robert Graysmith (340 cipher): Selective use of anagramming and other techniques, resulting in an incoherent message typical of anagram-based solutions.
- John Cecil: Relaxes the "one plaintext letter per symbol" constraint, resulting in easily fitting a pre-conceived plaintext.
