The achievements of cryptography, the art of writing and deciphering coded messages, have become a part of everyday life, especially in our age of electronic banking and the Internet. In Code Breaking , Rudolf Kippenhahn offers readers both anexciting chronicle of cryptography and a lively exploration of the cryptographer’s craft. Rich with vivid anecdotes from a history of coding and decoding and featuring three new chapters, this revised and expanded edition makes the often abstruse art of deciphering coded messages accessible to the general reader and reveals the relevance of codes to our everyday high-tech society. A stylishly written, meticulously researched adventure, Code Breaking explores the ways in which communication can be obscured and, like magic, made clear again.
