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.
