Napier's Bones
A simple and free HyperCard 2.1 stack that illustrates how Napier's Bones are used
as a calculator. Authored by Ken Dunham, 1994.
Cryptogrammer 1.0
This is a free program that presents users with an enciphered message using random
alphabet substitution. It's easy to use, free, and a great addition to the Macintosh
computer use aspect of the cryptology unit.
Cryptology Package
I have a set of comprehensive lessons, over 50, along with teacher plans, objectives, and three software packages for the Macintosh platform: CryptoMath, CryptoCreator, and Map Cipher Maker. This package is now a commercial product, http://eoni.com/~kdunham/cm.html.
CaPs ChAnGeR 1.0
This program is part of a copyrighted book "The HyperCard Roundup," co-authored by
Ken Dunham and Sharon Porter. It illustrates how ASCII values are used to translate
uppercase and lowercase letters into the opposing text case. It is included with
the book, still unpublished, as a free utility for transforming uppercase documents into
normally formatted documents with upper and lower case text. Contact Ken Dunham
if you are interested in a copy.
Cryptology FAQ
A Cryptology FAQ is available online via newsgroups but is fairly technical regarding
modern encryption processes used by computers in today's market. This document may
be more appropriate for computer science majors at the university level.
*I've also programmed a simple HyperCard stack that translates plain text into ASCII numbers or offset alphabet values. If you are interested in any of the products listed on this page feel free to mail me at kdunham@eoni.com.
