Java Cryptography Extensions

For a long time, there has been a need for a practical, down-to-earth developers book for the Java Cryptography Extension. I am very happy to see there is now a book that can answer many of the technical questions that developers, managers, and researchers have about such a critical topic. I am sure that this book will contribute greatly to the success of securing Java applications and deployments for e-business. --Anthony Nadalin, Java Security Lead Architect, IBMFor many Java developers and software engineers, cryptography is an "on-demand" programming exercise, where cryptographic concepts are shelved until the next project requires renewed focus. But considerations for cryptography must be made early on in the design process and it’s imperative that developers know what kinds of solutions exist. One of Java’s solutions to help bridge the gap between academic research and real-world problem solving comes in the form of a well-defined architecture for implementing cryptographic solutions. However, to use the architecture and its extensions, it is important to recognize the pros and cons of different cryptographic algorithms and to know how to implement various devices like key agreements, digital signatures, and message digests, to name a few.In Java Cryptography Extensions (JCE), cryptography is discussed at the level that developers need to know to work with the JCE and with their own applications but that doesn’t overwhelm by packing in details unimportant to the busy professional. The JCE is explored using numerous code examples and instructional detail, with clearly presented sections on each aspect of the Java library. An online open-source cryptography toolkit and the code for all of the examples further reinforces the concepts covered within the book. No other resource presents so concisely or effectively the exact material needed to begin utilizing the JCE. Written by a seasoned veteran of both cryptography and server-side programming Covers the architecture of the JCE, symmetric ciphers, asymmetric ciphers, message digests, message authentication codes, digital signatures, and managing keys and certificates

Security is paramount for any application. In Java, cryptography is key to the secure storage and transmission of data: to and from resources, users, and APIs. This course teaches the basics of Java cryptography using the Java Development Kit (JDK) crypto libraries: Java Cryptography Architecture (JCA) and Java Cryptography Extensions (JCE). Learn basic cryptography concepts and terms, including symmetric and asymmetric encryption, hashing, and digital signatures. Then find out how to use the cryptographic services or "engine classes" in JCA and JCE, such as Cipher, KeyGenerator, MessageDigest, and Signature, to enforce secure messaging and data storage. Plus, discover how to build a Java keystore to manage your repository of keys and certificates. Instructor Frank Moley uses his 16+ years of experience as a software developer and security architect to guide you through this complex topic.

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.

Cryptography is the gold standard for security. It is used to protect the transmission and storage of data between two parties by encrypting it into an unreadable format. Cryptography has enabled the first wave of secure transmissions, which has helped fuel the growth of transactions like shopping, banking, and finance over the world's biggest public network, the Internet. Many Internet applications such as e-mail, databases, and browsers store a tremendous amount of personal and financial information, but frequently the data is left unprotected. Traditional network security is frequently less effective at preventing hackers from accessing this data. For instance, once-private databases are now completely exposed on the Internet. It turns out that getting to the database that holds millions of credit card numbers-the transmission-is secure through the use of cryptography, but the database itself isn't, fueling the rise of credit card information theft. A paradigm shift is now under way for cryptography. The only way to make data secure in any application that runs over the Internet is to use secret (also known as private) key cryptography. The current security methods focus on securing Internet applications using public keys techniques that are no longer effective. In this groundbreaking book, noted security expert Nick Galbreath provides specific implementation guidelines and code examples to secure database and Web-based applications to prevent theft of sensitive information from hackers and internal misuse.

This is a practical guide to building a secure enterprise infrastructure with J2SE and J2EE technologies. This text explains how J2SE and J2EE security architectures relate to each other, and also covers the security aspects of servlets, JSP and EJB.

One of Java's most striking claims is that it provides a secure programming environment. Yet despite endless discussion, few people understand precisely what Java's claims mean and how it backs up those claims. If you're a developer, network administrator or anyone else who must understand or work with Java's security mechanisms, Java Security is the in-depth exploration you need.Java Security, 2nd Edition, focuses on the basic platform features of Java that provide security--the class loader, the bytecode verifier, and the security manager--and recent additions to Java that enhance this security model: digital signatures, security providers, and the access controller. The book covers the security model of Java 2, Version 1.3, which is significantly different from that of Java 1.1. It has extensive coverage of the two new important security APIs: JAAS (Java Authentication and Authorization Service) and JSSE (Java Secure Sockets Extension). Java Security, 2nd Edition, will give you a clear understanding of the architecture of Java's security model and how to use that model in both programming and administration.The book is intended primarily for programmers who want to write secure Java applications. However, it is also an excellent resource for system and network administrators who are interested in Java security, particularly those who are interested in assessing the risk of using Java and need to understand how the security model works in order to assess whether or not Java meets their security needs.
