Abstract
Abstract Elizebeth Smith Friedman has been credited with breaking hundreds of encryption systems during Prohibition, yet few complete examples exist. Using material available in the Elizebeth Smith Friedman archives at the Marshall Library, examples of a variety of encryption systems are presented. Complete examples include original ciphertext, plaintext, and a description of the encryption process. Friedman’s cryptanalysis of some of these messages is described.
期刊介绍：
Cryptologia is the only scholarly journal in the world dealing with the history, the technology, and the effect of the most important form of intelligence in the world today - communications intelligence. It fosters the study of all aspects of cryptology -- technical as well as historical and cultural. The journal"s articles have broken many new paths in intelligence history. They have told for the first time how a special agency prepared information from codebreaking for President Roosevelt, have described the ciphers of Lewis Carroll, revealed details of Hermann Goering"s wiretapping agency, published memoirs - written for it -- of some World War II American codebreakers, disclosed how American codebreaking affected the structure of the United Nations.
