| − | = Solvers =
| + | UPDATE: |
| | | | |
| − | AZDecrypt's main window has a list of solvers. Each one is a type of hillclimber that specializes in different types of ciphers:
| + | This document has been moved to my GitHub repository for AZDecrypt. |
| − | * Substitution
| |
| − | ** Simple substitution ciphers (including homophonic substitution)
| |
| − | * Substitution + columnar rearrangement
| |
| − | ** A combination of simple substitution and moving columns around.
| |
| − | * Substitution + columnar transposition
| |
| − | ** A combination of simple substitution and [https://en.wikipedia.org/wiki/Transposition_cipher#Columnar_transposition columnar transposition].
| |
| − | * Substitution + crib grid
| |
| − | * Substitution + crib list
| |
| − | * Substitution + monoalphabetic groups
| |
| − | * Substitution + nulls and skips
| |
| − | ** Tries to figure out if certain symbols in a substitution cipher don't actually contribute towards the plaintext.
| |
| − | ** A "null" is a position in the cipher text that does not translate to plaintext (and is ignored during decryption). The solver will consider different positions to be nulls, and exclude them prior to the next steps of decryption.
| |
| − | ** A "skip" is a missing symbol that is inserted at some position in the cipher. The solver will put them in different positions of the ciphertext before proceeding to the next steps of decryption.
| |
| − | ** [http://www.zodiackillersite.com/viewtopic.php?f=81&t=4125 More info]
| |
| − | * Substitution + polyphones
| |
| − | * Substitution + row bound
| |
| − | * Substitution + row bound fragments
| |
| − | * Substitution + sequential homophones
| |
| − | * Substitution + simple transposition
| |
| − | * Substitution + sparse polyalphabetism
| |
| − | * Substitution + units
| |
| − | ** Jarl's note on using this solver on nomenclator type ciphers:
| |
| − | *** After launching the solver a menu will pop up. You can set the Unit as Symbol or Horizontal sequence, the Mode to Replace with new symbols. If selected Horizontal sequence set the Horizontal sequence to 1. The Key length start determines the amount of Symbols or Horizontal sequences to be replaced. And set Replace, # of symbols per instance to 2 if you want to replace symbols with bigrams for example.
| |
| − | * Substitution + vigenere
| |
| − | * Substitution + vigenere word list
| |
| − | * Bigram substitution
| |
| − | * Higher-order homophonic
| |
| − | * Merge sequential homophones
| |
| | | | |
| − | = Pangrams =
| + | [https://github.com/doranchak/azdecrypt#azdecrypt Click here to view it.] |
| − | AZDecrypt was not able to solve this cipher with default settings:
| |
| − | | |
| − | ABC DEFGH IJKLM NKO PEQRS KTCJ U VUWX YKZ RUGH QX IKO LFAB NFTC YKWCM VFDEKJ PEZS
| |
| − | | |
| − | The plaintext consists of two pangrams:
| |
| − | | |
| − | THE QUICK BROWN FOX JUMPS OVER A LAZY DOG PACK MY BOX WITH FIVE DOZEN LIQUOR JUGS
| |
| − | | |
| − | Jarl's fix, under "Options -> Solvers":
| |
| − | * Boost Entropy weight to 10
| |
| − | * Click the "Normalize n-gram factor" button
| |
| − | | |
| − | Now it can solve the cipher.
| |
| − | | |
| − | = Batch mode =
| |
| − | | |
| − | In batch mode (processing multiple ciphers), under default settings, AZDecrypt will not write output files if newly cracked ciphers' scores are not higher than previously cracked ciphers' scores. To change this, set "Output improvements only" to "No" in "Options -> Solvers"
| |
| − | | |
| − | = Solving "Ambiguous Caesar shift" ciphers (aka Hafer ciphers or Hafer homophonic ciphers) =
| |
| − | | |
| − | Instructions and details on configuring AZDecrypt to solve these kinds of ciphers [http://zodiackillersite.com/viewtopic.php?p=81511#p81511 can be found here.]
| |
| − | | |
| − | The description of the encipherment system [http://zodiackillersite.com/viewtopic.php?p=81498#p81498 is here.]
| |
| − | | |
| − | Jarlve posted a new version of AZDecrypt that can solve Hafer ciphers [http://zodiackillersite.com/viewtopic.php?p=81853#p81853 here.]
| |
| − | | |
| − | = Polyphone solver improvements =
| |
| − | | |
| − | Jarl has added improvements to the polyphone solver. [http://zodiackillersite.com/viewtopic.php?p=81694#p81694 Details here].
| |
| − | | |
| − | = Compute score for a given plaintext =
| |
| − | | |
| − | Sometimes, you might want to know what score AZDecrypt would give to a piece of plaintext. There is not yet an exact feature for this, but you can achieve it this way: Use the "Substitution + crib grid" solver, click on Show cipher and then type in the letters of the plain text. Though you will have to leave one letter uncribbed for it to work.
