Release NotesCryptology, 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. This 4th edition has again been revised
and extended in many technical and biographical details.
