Chapter 7. Message Digests and Digital Signatures
In Chapter 5,"An Introduction to Cryptography," and Chapter 6,"Key Management and Digital Certificates," you were introduced to message digests and digital signatures. These are important elements of Java security because they provide the basic mechanism for trusted code distribution. In this chapter, you'll take a closer look at message digests and digital signatures, study their classes and interfaces, and gain practical experience in creating digests and signatures. You'll also cover message authentication codes (MACs) and learn how they can be used to protect the integrity of messages that are sent over insecure communication channels.
