This book covers cryptographic programming in Java. Java 1.1 and Java 1.2 provide extensive support

for cryptography with an elegant architecture, the Java Cryptography Architecture (JCA). Another set

of classes, the Java Cryptography Extension (JCE), provides additional cryptographic functionality.

This book covers the JCA and the JCE from top to bottom, describing the use of the cryptographic

classes as well as their innards.
