Beginning Cryptography with Java (eBook)

Beginning Cryptography with Java

While cryptography can still be a controversial topic in the
programming community, Java has weathered that storm and provides a
rich set of APIs that allow you, the developer, to effectively
include cryptography in applications-if you know how.

This book teaches you how. Chapters one through five cover the
architecture of the JCE and JCA, symmetric and asymmetric key
encryption in Java, message authentication codes, and how to create
Java implementations with the API provided by the Bouncy Castle
ASN.1 packages, all with plenty of examples. Building on that
foundation, the second half of the book takes you into higher-level
topics, enabling you to create and implement secure Java
applications and make use of standard protocols such as CMS, SSL,
and S/MIME.

What you will learn from this book

* How to understand and use JCE, JCA, and the JSSE for encryption
and authentication

* The ways in which padding mechanisms work in ciphers and how to
spot and fix typical errors

* An understanding of how authentication mechanisms are
implemented in Java and why they are used

* Methods for describing cryptographic objects with ASN.1

* How to create certificate revocation lists and use the Online
Certificate Status Protocol (OCSP)

* Real-world Web solutions using Bouncy Castle APIs

Who this book is for

This book is for Java developers who want to use cryptography in
their applications or to understand how cryptography is being used
in Java applications. Knowledge of the Java language is necessary,
but you need not be familiar with any of the APIs discussed.

Wrox Beginning guides are crafted to make learning
programming languages and technologies easier than you think,
providing a structured, tutorial format that will guide you through
all the techniques involved.
