United States Diplomatic Codes and Ciphers, 1775-1938 is the first basic reference work on American diplomatic cryptography. Weber's research in national and private archives in the Americas and Europe has uncovered more than one hundred codes and ciphers. Beginning with the American Revolution, these secret systems masked confidential diplomatic correspondence and reports.During the period between 1775 and 1938, both codes and ciphers were employed. Ciphers were frequently used for American diplomatic and military correspondence during the American Revolution. At that time, a system was popular among American statesmen whereby a common book, such as a specific dictionary,was used by two correspondents who encoded each word in a message with three numbers. In this system, the first number indicated the page of the book, the second the line in the book, and the third the position of the plain text word on that line counting from the left. Codes provided the most common secret language basis for the entire nineteenth century.Ralph Weber describes in eight chapters the development of American cryptographic practice. The codes and ciphers published in the text and appendix will enable historians and others to read secret State Department dispatches before 1876, and explain code designs after that year.

Samuel Steward (1909–93) was an English professor, a tattoo artist for the Hells Angels, a sexual adventurer who shared the considerable scope of his experiences with Alfred Kinsey, and a prolific writer whose publications ranged from scholarly articles to gay erotica (the latter appearing under the pen name Phil Andros). Perhaps his oddest authorial role was as a monthly contributor between 1944 and 1949 to the Illinois Dental Journal, an obscure trade publication for dentists, where writing as Philip Sparrow he produced a series of charming, richly allusive, and often quirky essays on a wildly eclectic assortment of topics. In Philip Sparrow Tells All, Jeremy Mulderig has collected thirty of these engaging but forgotten columns, prefacing them with revealing introductions that relate the essays to people and events in Steward’s life and to the intellectual and cultural contexts in which he wrote during the 1940s. In these essays we encounter such famous friends of Steward as Gertrude Stein, André Gide, and Thornton Wilder. We hear of his stint as a holiday sales clerk at Marshall Field’s (where he met and seduced fellow employee Rock Hudson), of his roles as an opera and ballet extra in hilariously shoddy costumes, of his hoarding tendencies, his disappointment with the drabness of men’s fashions, and his dread of turning forty. We go along with him to a bodybuilding competition and a pet cemetery, and together we wander the boulevards of Paris and the alleys of Algiers. Throughout, Mulderig’s entertaining annotations explain the essays’ wide-ranging allusions and also highlight their gay subtext, which constituted a kind of private game that Steward played with his mostly oblivious audience of Midwestern dentists. The first collection of any of Samuel Steward’s writings to be republished since his death in 1993, Philip Sparrow Tells All makes these lost essays available to a broad readership that Steward imagined but never actually enjoyed when he wrote them. In doing so, it takes a major step toward documenting his important place in twentieth-century gay literature and history.

The first cultural history of early modern cryptography, this collection brings together scholars in history, literature, music, the arts, mathematics, and computer science who study ciphering and deciphering from new materialist, media studies, cognitive studies, disability studies, and other theoretical perspectives. Essays analyze the material forms of ciphering as windows into the cultures of orality, manuscript, print, and publishing, revealing that early modern ciphering, and the complex history that preceded it in the medieval period, not only influenced political and military history but also played a central role in the emergence of the capitalist media state in the West, in religious reformation, and in the scientific revolution. Ciphered communication, whether in etched stone and bone, in musical notae, runic symbols, polyalphabetic substitution, algebraic equations, graphic typographies, or literary metaphors, took place in contested social spaces and offered a means of expression during times of political, economic, and personal upheaval. Ciphering shaped the early history of linguistics as a discipline, and it bridged theological and scientific rhetoric before and during the Reformation. Ciphering was an occult art, a mathematic language, and an aesthetic that influenced music, sculpture, painting, drama, poetry, and the early novel. This collection addresses gaps in cryptographic history, but more significantly, through cultural analyses of the rhetorical situations of ciphering and actual solved and unsolved medieval and early modern ciphers, it traces the influences of cryptographic writing and reading on literacy broadly defined as well as the cultures that generate, resist, and require that literacy. This volume offers a significant contribution to the history of the book, highlighting the broader cultural significance of textual materialities.

This textbook presents a fascinating review of cryptography and cryptanalysis, from the earliest known cryptographic systems of 2,500 years ago up to modern computer-based systems. The text relates the earliest use of the monoalphabetic cipher in the ancient world, the development of the “unbreakable” Vigenère cipher, and an account of how cryptology entered the arsenal of military intelligence during the American Revolutionary War. Moving on to the American Civil War, the book explains the solution of the Vigenère ciphers used by the Confederates and the use of telegraph codes, before investigating the development of cipher machines throughout World War I and II, including development of the first digital computer, Colossus. The exposition then explores cryptology in the computer age, from public-key cryptography and web security to criminal cyber-attacks and cyber-warfare. The role of cryptography in the Internet of Things is also discussed, along with the potential impact of quantum computing. Topics and features: Presents a history of cryptology from ancient Rome to the present day, with a focus on cryptology in the 20th and 21st centuries Provides engaging examples illustrating use of cryptographic algorithms in different historical periods Reviews algorithms and devices used to create secret messages, and the various methods for breaking such messages Describes notable contributions to cryptology by Herbert Yardley, William and Elizebeth Smith Friedman, Lester Hill, Agnes Meyer Driscoll, and Claude Shannon Examines unsolved mysteries in cryptology, such as the Voynich Manuscript, the Beale Ciphers, the Kryptos sculpture, and the Zodiac killer ciphers This engaging work is ideal as both a primary text for courses on the history of cryptology, and as a supplementary text for advanced undergraduate courses on cryptology and computer security. No prior background in mathematics is assumed, beyond what would be encountered in an introductory course on discrete mathematics.

Ludwig Wittgenstein's works encompass a huge number of published philosophical manuscripts, notebooks, lectures, remarks, and responses, as well as his unpublished private diaries. The diaries were written mainly in coded script to interpolate his writings on the philosophy of language with autobiographic passages, but were previously unknown to the public and impossible to decode without learning the coding system. This book deciphers the cryptography of the diary entries to examine what Wittgenstein's personal idiom reveals about his public and private identities. Employing the semiotic doctrine of Charles S. Peirce, Dinda L. Gorlée argues that the style of writing reflects the variety of Wittgenstein's emotional moods, which were profoundly affected by his medical symptoms. Bringing Peirce's reasoning of abduction together with induction and deduction, the book investigates how the semiosis of the emotional, energetic, and logical interpretations of signs and objects reveal Wittgenstein's psychological states in the coded diaries.
