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.This book shows how to understand and use JCE,
JCA, and the JSSE for encryption and authentication. It
provides the ways in which padding mechanisms work in
ciphers and how to spot and fix typical errors. It
offers an understanding of how authentication mechanisms
are implemented in Java and why they are used. It
provides methods for describing cryptographic objects
with ASN.1.It shows how to create certificate revocation
lists and use the Online Certificate Status Protocol
(OCSP). It includes real-world Web solutions using
Bouncy Castle APIs.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. |
