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"

In v1.2, "Batch ciphers (non-substitution)" has been added to the File menu.

Solving "Ambiguous Caesar shift" ciphers (aka Hafer ciphers or Hafer homophonic 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.

Jarlve posted a new version of AZDecrypt that can solve Hafer ciphers here.

Polyphone solver improvements

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

Compute score for a given plaintext

Select the "Non-substitution" solver.
