U.S. Army Guide to Code Breaking

"From the introduction of this document, the U.S. Army's field manual guide to Cryptanalysis: 'This manual presents the basic principles and techniques of cryptanalysts and their relation to cryptography. Cryptanalytics is the art and science of solving unknown codes and ciphers.'"

I have read this document quite a little , but I assume it would be an interesting read. I'll continue with it, when time permits.
