Pangrams

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

Instructions and details on configuring AZDecrypt to solve these kinds of ciphers can be found here.

The description of the encipherment system is here.

Polyphone solver improvements

Jarlve has added improvements to the polyphone solver. Details here.
