crank

Crank is a project to provide a GUI toolkit to facilitate (and where possible, automate) the breaking of classical (pen-and-paper) cryptosystems. Initial focus is on the cryptanalysis of monoalphabetic substitution ciphers.

Release Notes: A log window has been added for messages from running algorithms. A scheme interface now exists using Guile, and this has been used to create preset groups of componant settings. Two new componants have also been included: a simulated annealing algorithm, and the grid transposition cipher from the stable branch.

Release Notes: Crank has been largely rewritten to support a componant architecture, and this is the first release featuring this. It is hoped that by splitting up the various cipher classes, cryptanalysis algorithms, and plaintext evalution functions, code reuse can be maximised.

Release Notes: The "makefile" has been converted to use autoconf, and a "make install" target has been added. The GUI now has a toolbar. A new plugin type for plaintext comparisons has been introduced.

Release Notes: Route transposition cipher and concealment cipher tools have been added.

Release Notes: This release includes a new editable source text pane, making operation of plug-ins much more obvious, as well as various cosmetic improvements.
