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