"Elementary Cryptanalysis" by Helen Fouché Gaines is a scientific publication written in the late 1930s. This work serves as an instructional guide on the analysis and deciphering of various types of ciphers, primarily aimed at enthusiasts and students interested in cryptography. The book claims to fill a significant gap in English-language literature regarding cryptanalysis, providing readers with both theoretical knowledge and practical examples of how to solve cryptograms. The opening portion of the text introduces the definitions of key terms in cryptography, such as cryptography and cryptanalysis, while also highlighting the scarcity of accessible works on the latter topic for general readers. Gaines outlines the main types of ciphers, including concealment, transposition, and substitution, and emphasizes that her treatise focuses on basics rather than historical or literary aspects of ciphers. The preface sets up an educational framework to equip readers with the fundamentals they need to analyze and solve cryptograms, supported by a wealth of examples and exercises designed to test their skills.
