About This Book

The text surveys the practice and history of secret writing, explaining why correspondents conceal messages and tracing techniques from primitive concealments (shaved-head messages, hollowed animals, wax tablets) to mechanical devices like the scytale and to systematic methods such as abbreviation, agreed signs, substitution, and encipherment. It combines historical anecdotes, descriptions of practical procedures and sample systems, and commentary on how ciphers are constructed and broken, offering both steganographic and cryptographic perspectives.
