Java Cryptography (I assume you're talking about the one from O'Reilly) by Knudsen is a good book and does explain the crypto side of Java in-depth. Of course, you can take a look at our book if you want examples of using cryptography in the context of a real application. The books actually complement each other well - Java Cryptography talks more about the theory of crypto and the JCE and our book focuses on the *application* of Java / J2EE security in general (of which cryptography and the JCE is an important part). The crypto APIs (more commonly known as the JCE) are included with every version of J2SE 1.4 and above (you get them for free with the base JDK). If you want more algorithms and more comprehensive implementations, I'd recommend the Bouncy Castle JCE provider (available from http://www.bouncycastle.org). Hope this helps!
