Java Cryptography page 20 To verify a fingerprint, call the people who issued the certificate and have them read off the numbers of the fingerprint. Another option is for the CA to widely publish their self-signed certificate's fingerprint, perhaps in newspapers and magazines as well as online. If you obtain a fingerprint from several sources, and they all match the fingerprint on the self-signed certificate you possess, then the certificate is likely to be trustworthy. Currently, most self-signed certificates are embedded into web browsers. When you download and run a browser, it can recognize certificates issued by a dozen or so popular CAs, using internal self-signed certificates from these CAs. How do you know that somebody tricky hasn't modified the self-signed certificates as you downloaded the browser? You don't.
Chapter 1: 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. 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.
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.
Stay ahead with the world's most comprehensive technology and business learning platform.

If you decide to participate, a new browser tab will open so you can complete the survey after you have completed your visit to this website. Thanks in advance for your time. Skip to content. If you're worried about this attack, you should verify the self-signed certificate fingerprints in the browser before you accept any certificates issued by these CAs. Alternately, you should download the browser in a secure manner, perhaps using SSL see Chapter 7.
Certificate Authorities: At Odds with the Internet? Some people believe that hierarchical certificates are not a good way to authenticate users. The existence of many certificates chains, all leading back to a small group of CAs, is seen as a security weakness. It does focus a lot of attention on the CA's private key. Anyone possessing this key can issue all sorts of bogus certificates and have them trusted by a large group of users.
They are hard at work on a better solution, called Meta Certificates, but the hierarchical certificate structure remains a de facto standard. They are used to create cryptographic keys and, in some cases, to encrypt or sign data.

A random number is one whose value cannot be predicted. A random number generator RNG is a device that produces random numbers. It's fairly easy for humans to generate random numbers. You can sit down with a pair of dice or a deck of cards, and generate as many random numbers as you want. It's much harder to convince a computer to generate random numbers.
Java Cryptography Extensions - 1st Edition
Computers are designed to be methodical and deterministic. Some computers can use specialized hardware to generate random numbers, by measuring an unstable electronic circuit or radioactive decay or some other random process. Most of us, however, don't have this kind of hardware. Furthermore, such solutions tend to be very platform-specific, which is not good for Java programmers. As with horseshoes and hand grenades, "close" has to be good enough.
Jon is particularly interested in software design and how to influence teams in building good software, the latter which takes up more and more of his time. On most days you will find Jon riding one of his bikes, drinking coffee at the local cafe and being heckled by colleagues as he wistfully remembers the time he spent all day, every day writing code.
