This vintage book contains Alexander D?Agapeyeff?s famous 1939 work, ?Codes and Ciphers - A History of Cryptography?. Cryptography is the employment of codes and ciphers to protect secrets, and it has a long and interesting history. This fantastic volume offers a detailed history of cryptography from ancient times to modernity, written by the Russian-born English cryptographer, Alexander D'Agapeyeff. Contents include: ?The beginnings of Cryptography?, ?From the Middle Ages Onwards?, ?Signals, Signs, and Secret Languages?, ?Commercial Codes?, ?Military Codes and Ciphers?, ?Types of Codes and Ciphers?, ?Methods of Deciphering?, etcetera. Many antiquarian texts such as this, especially those dating back to the 1900s and before, are increasingly hard to come by and expensive, and it is with this in mind that we are republishing this book now in an affordable, modern, high quality edition. It comes complete with a specially commissioned new biography of the author.

This accessible textbook presents a fascinating review of cryptography and cryptanalysis across history. 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 how the Union solved the Vigenère ciphers used by the Confederates, before investigating the development of cipher machines throughout World War I and II. This is then followed by an exploration of cryptology in the computer age, from public-key cryptography and web security, to criminal cyber-attacks and cyber-warfare. Looking to the future, 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; reviews the different types of cryptographic algorithms used to create secret messages, and the various methods for breaking such secret messages; provides engaging examples throughout the book illustrating the use of cryptographic algorithms in different historical periods; describes the notable contributions to cryptology of Herbert Yardley, William and Elizebeth Smith Friedman, Lester Hill, Agnes Meyer Driscoll, and Claude Shannon; concludes with a review of tantalizing unsolved mysteries in cryptology, such as the Voynich Manuscript, the Beale Ciphers, and the Kryptos sculpture. 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 computer security. No prior background in mathematics is assumed, beyond what would be encountered in an introductory course on discrete mathematics.

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.

Readers examine eight codes and ciphers that could not be cracked. The ancient Phaistos Disc, circa 1700 BCE, the Voynich Manuscript with its strange illustrations from the fifteenth century, the location of the buried treasure of 1819 as described in the Beale Papers, Edward Elgar’s Dorabella Cipher of 1897, the Chaocipher of 1918, the D’Agapeyeff Challenge Cipher of 1939, the Zodiac Killer’s 408 Cipher from the late 1960s, and the Kryptos Monument ciphers of 1990 are all undeciphered today. These riddles have eluded the best cryptographers, but, with time, new tools, and a little luck, the eight codes will someday be cracked.

This intriguing and revelatory history of cryptology ranges from the early days of code-making and code-breaking in ancient Egypt, Sparta, and Rome to the present day when it has slipped beyond the tight control of governments and now affects all our lives whenever we use our cell phones or connect to the internet. Subjects covered here include Mary Queen of Scots' cryptic messages when she was plotting against her cousin Elizabeth I; the codes used by George Washington for military and political purposes; and code-breaking during World Wars I and II, including the Enigma Machine. Those who invent codes and those who break them are fascinating characters. This is their story.
