I'm happy to announce that the final release of Apache Java XML Security 1.4.2 is now available. See the web site http://santuario.apache.org for more details on the release or download it from http://xml.apache.org/security/dist/java-library/ The main highlights of this release are: 22 bugs and rfes have been fixed A new implementation of C14N 1.1 is supported. A potentially serious XML...

JSR 105 (XML Digital Signature API) is included with JDK 6, but is also available separately, for example as part of the Apache XML Security Project. This allows you to use the JSR with earlier JDK/JREs such as JDK 1.4 or JDK 5. If you do this, however, be aware that the JSR 105 service provider implementation is not included by default with JDK 1.4 or JDK 1.5, so you may get some exceptions...

In a previous blog entry, I wrote about how to enable logging to get debugging output when using the Java XML DSig API to validate an XML Signature. There are also various methods in the API that you can invoke to get similar information. Here are a couple of those which are probably most useful: SignedInfo.getCanonicalizedData This method will return an InputStream containing the canonicalized...

Wow, JavaOne is here again, next week to be exact! I hope you are going. We have a bunch of new security features in the JDK and a number of things we are thinking about for the future. Come to one of our sessions to learn or discuss more about Java Security: 1. Ask the Experts about Java Security in the Java Pavilion (booth #1538) Time: Tuesday, 12:30 - 1:30 PM 2. Session ID: TS-2594...

In a recent blog of my colleague Andreas Sterbenz, he asks the Java community for input on the security features for JDK 7. Specifically, he writes: Let us know your suggestions for features in the security area including topics such as crypto, PKI, SSL, Kerberos, security manager + policy, authorization + JAAS, SASL, XML security, secure coding, performance, ease of use and administration, and...

There's a new java.sun.com article titled Java XML Digital Signatures. It includes an introduction to XML digital signatures and to the new Java XML Digital Signatures APIs (JSR 105). It also discusses how to accelerate Java XML digital signature performance using cryptographic hardware accelerators such as Sun's UltraSPARC T1 processor with cryptographic acceleration support. The article was...

In XML Signatures, Reference elements use URIs to describe the data that is to be digested and signed. Adding support for your own URI dereferencing implementation is pretty straightforward in JSR 105. First you need to create a concrete implementation of the javax.xml.crypto.URIDereferencer interface, ex: public class MyURIDereferencer implements URIDereferencer { ... There is only one...

In a previous blog entry, I discussed how to determine what caused an invalid XML Signature and provided some code snippets. But for some programmers, this information may not be enough, and you may want to know more details. Well then, good news. The reference implementation of XML DSig has extensive logging support, that when enabled, will provide you with lots of additional information. The...

When validating an XML Signature using the Java XML DSig API, it returns a simple boolean indicating if the signature is valid or not: // Validate the XMLSignature boolean coreValidity = xmlSignature.validate(valContext); If it is valid, then great ... no worries. But what if it is invalid? How can you determine exactly what caused the failure? Perhaps you used the wrong key to validate the...

This being my first blog entry, I'll quickly introduce myself. I'm an engineer at Sun Microsystems working on Java (SE) Security, primarily in the areas of XML Security, PKI and access control. At next week's JavaOne, our team are presenting a talk and a BOF. Here are the details: TS-7247 New Security and Networking Features for Web Services, Smart Cards, and More Security and networking...
