God, don't say that, you'll get that Emily Dickinson wacko going again.
Oh yeah. I guess I didn't think of that...;) But on this topic, I just got back from one of the used bookstores with a copy of, Secrets of Making and Breaking Codes Hamilton Nickels ISBN 0-8065-1563-5 $7 US ($2 used) TOC: 1. General Information 2. Concealment 3. Transposition Systems 4. Basic Substitution Systems 5. Polyalphabetic Cipher Systems 6. Code Machines 7. Codemaster System 8. Field Message Systems A. Common Words and Letters Only 133 pages so it obviously isn't a deep tomb. However it does have some BASIC programs that look like a good place to at least start. If there is any interest I could put up some old tables [1] of: - Letter/word frequency: English, French, German, Italian, & Spanish - Notes on Japanese [1] Cryptography: the science of secret writing Laurence Dwight Smith ISBN 0-486-20247-x (Dover) $5 US ____________________________________________________________________ He is able who thinks he is able.
