My website is all about ciphers and solving them with a computer. There are three themes, and you can navigate within them or go anywhere in the site by using the Site Map

Python Tutorial
Many people have a computer but are not getting full value from it because they are unaware of how to write programs. For them I have written this tutorial.

In the teaching I am going to use examples drawn from the interesting world of ciphers, though the programming methods learned will be equally applicable to any application.

Computer Solving
This theme covers algorithms and solving programs that you can implement on my site.

A major focus is on the Churn algorithm, the most effective for solving Classical ciphers.

Interesting Ciphers
Read about interesting ciphers that I have researched.

Rasterschluessel 44 — the epitome of hand field ciphers

Chaocipher — that kept its secret for ninety years

Floradora — believed to be impregnable by the Germans but broken by the Allies.

Also have a look at this highly secure Latin Square cipher with a program you can run.
