Cryptography the science of secret writing is the biggest baddest securitytool in the application programmers arsenal. Cryptography provides threeservices that are crucial in secure programming. These include a cryptographiccipher that protects the secrecy of your data cryptographic certificateswhich prove identity authentication and digital signatures which ensureyour data has not been damaged or tampered with. This book covers cryptographicprogramming in Java. Java 1.1 and Java 1.2 provide extensive support forcryptography with an elegant architecture the Java Cryptography ArchitectureJCA. Another set of classes the Java Cryptography Extension JCE providesadditional cryptographic functionality. This book covers the JCA and the JCEfrom top to bottom describing the use of the cryptographic classes as well astheir innards. The book is designed for moderately experienced Java programmerswho want to learn how to build cryptography into their applications. No priorknowledge of cryptography is assumed. The book is peppered with usefulexamples ranging from simple demonstrations in the first chapter to fullblownapplications in later chapters. Topics include The Java CryptographyArchitecture JCA The Java Cryptography Extension JCE Cryptographicproviders The Sun key management tools Message digests digital signaturesand certificates X509v3 Block and stream ciphers Implementations of theElGamal signature and cipher algorithms A network talk application thatencrypts all data sent over the network An email application that encryptsits messages Covers JDK 1.2 and JCE 1.2. «
