The Apache XML Security for C++ library is an implementation of the XML Digital Signature and Encryption specifications, along with some additional XKMS code. It is designed to be easily ported to new platforms, and is generally tested on Windows, Linux, OS X, and Solaris. Other platforms with autoconf support may also work.
The library makes use of the Apache Xerces-C XML Parser and Xalan-C XSLT processor. The latter is used for processing XPath and XSLT transforms. The use of Xalan-C is optional, but without it, XPath and XSLT transformations cannot be performed.
The state of the Xalan-C project is unclear at this time, and these features should be viewed with caution.
In addition, the library currently uses OpenSSL to provide cryptographic functionality. The cryptographic interface is implemented via a thin wrapper layer, and development versions of implementations for the Windows Cryptographic API and NSS have also been implemented.
Version 2.0.2 of the Apache XML Security for C++ has been released.
This patch corrects a bug that can cause crashes in upstream applications. It is similar to, but not the same as, the one that was patched in V2.0.1, and resulted from further review of the code by the project that contributes all of the current manpower to the project. Appreciation is extended to the Shibboleth Project team for this review.
Version 2.0.1 of the Apache XML Security for C++ has been released.
This patch corrects a bug that can cause crashes in upstream applications.
Version 2.0.0 of the Apache XML Security for C++ has been released.
Please see the release notes for basic information on bugs addressed. As a major upgrade, this release includes a range of relative minor, but visible, changes to the API that are not explicitly noted there. There are no features of significance added in this version, merely some refactoring and removal of deprecated APIs.
