Book excerpt: This manual concerns the design of classic ciphers which can produce cryptograms just as unbreakable by cryptanalysis as cryptograms from the latest computer systems. Piracy then depends largely on how well access to the crypto key is controlled. Crypto key, whether stored digitally in computer memory with password access or as hard copy in a safe with combination lock access, is vulnerable to unintended access by pilfering, coercion, etc. Hence, classic ciphers with upgraded crypto key & security are still relevant. Classic ciphers can be computerized, of course, when data volumes warrant, but no computer programs are provided. Upgraded instructions for a general purpose cipher & 15 classics are provided. Very light on cryptanalysis. Aspects such as error control, compaction & compression are covered. Lucid articles are amply illustrated, referenced, indexed & logically grouped: CODES: Numeration & Notation, Character Sets, Telecommunications, Error Control, Compression & Compaction.
