Cryptology, for millennia a "secret science", is rapidly gaining in practical importance for the protection of communication channels, databases, and software. Beside its role in computerized information systems (public key systems), more and more applications within computer systems and networks are appearing, which also extend to access rights and source file protection. The first part of this book treats secret codes and their uses - cryptography. The second part deals with the process of covertly decrypting a secret code - cryptanalysis - where in particular advice on assessing methods is given. The book presupposes only elementary mathematical knowledge. Spiced with a wealth of exciting, amusing, and sometimes personal stories from the history of cryptology, it will also interest general readers.
Decrypted Secrets has become a standard book on cryptology. The new edition has been revised and extended in many details, particularly on the ENIGMA and other rotor machines, on cipher teletype machines, codenamed FISH by the British, and on key negotiation.
"The best single book on cryptology today" (David Kahn, Cryptologia)
"For those who work actively with cryptology this book is a must. For amateurs it is an important dictionary which in many cases will guide them to make their ciphers more secure." (Arne Fransén, International Intelligence History Study Group)
The revised, expanded 3rd edition of this classic cryptology reference offers a wealth of new technical and biographical material. Requiring minimal math, and spiced with amusing and sometimes personal accounts from the history of cryptology, it will interest a broad readership.
In today's unsafe and increasingly wired world cryptology plays a vital role in protecting communication channels, databases, and software from unwanted intruders. This revised and extended third edition of the classic reference work on cryptology now contains many new technical and biographical details. The first part treats secret codes and their uses - cryptography. The second part deals with the process of covertly decrypting a secret code - cryptanalysis, where particular advice on assessing methods is given. The book presupposes only elementary mathematical knowledge. Spiced with a wealth of exciting, amusing, and sometimes personal stories from the history of cryptology, it will also interest general readers.

"The best single book on cryptology today." -- Cryptologia (from a review of a previous edition)
From the reviews of the fourth edition:
"This comprehensive updated edition is divided into two sections. The first part of the book deals with The People and the second concentrates on The Machinery. … This volume includes 191 Figures, 29 Tables and 16 Color Plates, plus an Appendix. … Friedrich L. Bauer Professor Emeritus of Mathematics and Computer Science … has written an outstanding book on cryptology that belongs in your personal library or as a gift for a friend. … There are other fascinating sidelights to this excellent book." (The Cryptogram, Page 15, 2007)
"By far the best single work on the subject." -- David Kahn
