'The best book on codebreaking I have read', SIR DERMOT TURING
'Brings back the joy I felt when I first read about these things as
a kid', PHIL ZIMMERMANN 'This is at last the single book on
codebreaking that you must have. If you are not yet addicted to
cryptography, this book will get you addicted. Read, enjoy, and
test yourself on history's great still-unbroken messages!' JARED
DIAMOND is the Pulitzer Prize-winning author of Guns, Germs, and
Steel; Collapse; and other international bestsellers 'This is THE
book about codebreaking. Very concise, very inclusive and easy to
read', ED SCHEIDT 'Riveting', MIKE GODWIN 'Approachable and
compelling', GLEN MIRANKER This practical guide to breaking codes
and solving cryptograms by two world experts, Elonka Dunin and
Klaus Schmeh, describes the most common encryption techniques along
with methods to detect and break them. It fills a gap left by
outdated or very basic-level books. This guide also covers many
unsolved messages. The Zodiac Killer sent four encrypted messages
to the police. One was solved; the other three were not. Beatrix
Potter's diary and the Voynich Manuscript were both encrypted - to
date, only one of the two has been deciphered. The breaking of the
so-called Zimmerman Telegram during the First World War changed the
course of history. Several encrypted wartime military messages
remain unsolved to this day. Tens of thousands of other encrypted
messages, ranging from simple notes created by children to
encrypted postcards and diaries in people's attics, are known to
exist. Breaking these cryptograms fascinates people all over the
world, and often gives people insight into the lives of their
ancestors. Geocachers, computer gamers and puzzle fans also require
codebreaking skills. This is a book both for the growing number of
enthusiasts obsessed with real-world mysteries, and also fans of
more challenging puzzle books. Many people are obsessed with trying
to solve famous crypto mysteries, including members of the Kryptos
community (led by Elonka Dunin) trying to solve a decades-old
cryptogram on a sculpture at the centre of CIA Headquarters;
readers of the novels of Dan Brown as well as Elonka Dunin's The
Mammoth Book of Secret Code Puzzles (UK)/The Mammoth Book of Secret
Codes and Cryptograms (US); historians who regularly encounter
encrypted documents; perplexed family members who discover an
encrypted postcard or diary in an ancestor's effects;
law-enforcement agents who are confronted by encrypted messages,
which also happens more often than might be supposed; members of
the American Cryptogram Association (ACA); geocachers (many caches
involve a crypto puzzle); puzzle fans; and computer gamers (many
games feature encryption puzzles). The book's focus is very much on
breaking pencil-and-paper, or manual, encryption methods. Its focus
is also largely on historical encryption. Although manual
encryption has lost much of its importance due to computer
technology, many people are still interested in deciphering
messages of this kind.
