Cryptography, the science of secret writing, is the biggest, baddest security tool in the application programmer's arsenal. Cryptography provides three services that are crucial in secure programming. These include a cryptographic cipher that protects the secrecy of your data; cryptographic certificates, which prove identity (authentication); and digital signatures, which ensure your data has not been damaged or tampered with | JAVA Cryptography O REILLY Jonathan Kiiudiwn Java Cryptography Jonathan B. Knudsen First Edition May 1998 ISBN 1-56592-402-9 362 pages Java Cryptography teaches you how to write secure programs using Java s cryptographic tools. It includes thorough discussions of the package and the Java Cryptography Extensions JCE showing you how to use security providers and even implement your own provider. It discusses authentication key management public and private key encryption and includes a secure talk application that encrypts all data sent over the network. If you work with sensitive data you ll find this book indispensable. Table of Contents Preface 1 1.
