Beginning Cryptography with JavaWhile 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 forThis 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.
Customer Reviews & Comments
Cryptography is still a delicate issue with a lot of people. There are those, especially in certain law enforcement agencies, who believe that access to stong encryption should not be allowed in the hands of the general public. Indeed, there are export regulations that define encryption technology as munitions. ==At the other end of the scale, there is the simple fact that without secure data transmission, web based electronic commerce would simply be impossible.
This book is on the use of standard Java encryption libraries. This book is written for people who are Java developers and are trying to make use of cryptography in their applications. It presumes that you are familiar with the Java language, but it does not assume you have any familiarity with the encryption APIs. The book covers the recent updates in the security APIs with J2SE 5.0.
This book is very good from the programming point of view, it does not have a lot of history or the background technology of how encryption is done.
