- August 21, 2003
  The new XML Security Library 1.1.1 release adds <X509Data/> node templates support to xmlsec-nss (Tej); includes new functions for reading keys and certificates from memory for xmlsec-core and xmlsec-openssl (Joachim); fixes several problems in xmlsec configuration files (Roumen) and a bug in URI attribute XInclude processing.
- August 5, 2003
  A great patch from Tej that dramaticaly improves xmlsec-nss functionality deserves a minor version number update :). In addition to that, the new XML Security Library 1.1.0 release includes <X509Data/> node templates support for xmlsec-openssl (Roumen); separate pkg-config files for xmlsec-crypto libraries and minor documentation updates (including coding style and some useful commands for xmlsec developers in a new "HACKING" file).
- July 15, 2003
  There were several minor patches during last month and it's time to do a new XML Security Library 1.0.4 release to pick up them: x509 certificates names comparison function now supports multiple entries woth the same object name (Roumen); multiple build fixes; documentation mistypes fixes.
  Also I gave an XML Security presentation at OSCON 2003 last week. You can download slides here.
- June 17, 2003
  The XML Security Library 1.0.3 release adds PKCS#8 support for xmlsec-openssl (Tej) and fixes several configuration and portability problems.
- June 03, 2003
  The XML Security Library 1.0.2 release includes several fixes in xmlsec-nss configuration and linking options (Tej), PKCS21 files reading improvements, minor documentation and help file fixes. Also this release includes some code for XKMS support. This is absolutely not usable right now and not configured in by default. Please, don't use or even compile it in.
- April 28, 2003
  The XML Security Library 1.0.1 release is a maintanance release. It fixes several compilation problems found in 1.0.0 release on the following platforms: OpenBSD/sparc64, Win32 Wacom C, Sun Workshop CC 6.0. Also from now on Win32 MSVC port enables the threading support by default (this is a part of the Igor's change to LibXML2/LibXSLT/XMLSec libraries).If you don't use one of these platforms then you'll see no difference.
- April 17, 2003
  The XML Security Library 1.0.0 release is the major upgrade from 0.0.X version. The new version includes multiple crypto engines support (with "out of the box" support for OpenSSL, GnuTLS and NSS); simplified and cleaned internal structure and API; several performance and memory usage improvements; new or updated documentation (tutorial, API reference manual and examples).
- April 10, 2003
  The final release candidate XML Security Library 1.0.0rc1 is available for download. This release includes minor API polishing, complete API Reference Manual, new chapters in the tutorial and several new examples. Another big change is using major version number in library files to prevent collisions between different library versions.
  If no major problems will be found then the 1.0.0 release should happen in a week from now.
- April 8, 2003
  The new XML Security Library 0.0.15 release is a preparation for the upcomming 1.0.0 release and provides an ability to have both versions installed together on the same box. Also this release includes updated expired certificates for the regression test suite and a fix for minor bug in reading binary keys on Windows.
- March 26, 2003
  XML Security Library 0.1.1 release is the first release candidate for the new stable version of XML Security Library. A lot of internal changes including enchanced processing controls, performance improvements for XML transforms, new documentation, updated examples and many many other small things.
  Please try this release and report bugs. Again, it's the first release candidate and it's very important for me to get your feedback about it. Also if you are missing some features in the library it's the best time to ask!
- March 19, 2003
  XML Security Library 0.0.14 release includes several minor bugfixes in references URI processing, binary transforms processing and xmlsec command line utility.
- March 5, 2003
  The XML Security Library 0.1.0 release creates a framework for integrating XML Security Library with almost any crypto engine and even combining multiple crypto engines in one application. As an example, basic support for GnuTLS and NSS libraries is provided (digests, hmac and block ciphers).
  This is a pre-alpha release not recommended for production (please use the stable 0.0.X releases instead). The new 0.1.X API and ABI will defenetly change. However, if you plan to use XML Security Library with a new crypto engine and plan to write some code then you can start now. The "backend" API is pretty stable and I do not expect major changes.
- February 21, 2003
  XML Security Library 0.0.13 release fixes incorrect processing of signatures with more than 3 binary transforms in a row, improved pkcs12 files support and minor documentation update.
- January 26, 2003
  Two major fixes in HMAC and DES/AES algorithms are the reason for the new XML Security Library 0.0.12 release. Also there are few other minor features and bug fixes (see Changelog in the distribution for more details).
- December 3, 2002
  New XML Security Library 0.0.11 release fixes a major problem in Reference URI attribute processing. This release also includes several Win32 build process fixes from Igor.
- October 20, 2002
  Almost two months from previous release and a lot of minor enchancements are good reasons for the new XML Security Library 0.0.10 release:
  - Added a way to specify "current time" to verify certificates expiration against it;
  - Implemented XML results output format for the xmlsec command line utility;
  - Fixed XMLDSig examples and added a new one (thanks to Devin Heitmueller);
  - Resolved static link issue and a bunch of other improvements for Win32 platform builds (Igor Zlatkovic);
  - Added dynamic linking option for xmlsec command line utility to help Debian port (John Belmonte);
  - Minor bug fixes.
- August 26, 2002
  I've completelly screwed up. The release 0.0.8 was totally broken (I've simply packaged files from wrong CVS :) ) and I am doing a new 0.0.9 release to fix all the problems. Please upgrade to the new version if you use any of previous XML Security Library releases.
  I am really sorry for my stupid mistakes and I promise to never do releases on Friday :(
  And special thanks to Ferrell Moultrie for pointing this out.
- August 23, 2002
  XML Security Library 0.0.8 is released:
  - New errors reporting system is created and all the code is updated;
  - Added XPointer transform support;
  - Major enveloped and XPath transforms performance improvements;
  - Updated XPath 2 Filter implementation to reflect latest W3C specifications;
  - Man page for xmlsec utility is written;
  - Automatically generated API Reference
  - Manual (more than 370 symbols) is created;
  - Minor Win32 bug fixes from Igor;
  - Debian port from John Belmonte.
- July 11, 2002
  XML Security Library documentation created.
- July 10, 2002
  A new XML Security Library 0.0.7 release includes all small bug fixes for last month and a new LibXML2 library with improved canonicalization.
- May 28, 2002
  New LibXML 2.4.22 is released and new XML Security Library 0.0.6 is released:
  - Win32 port is added: the idea and most of the configuration scripts code was taken from LibXML2 (written by Igor Zlatkovic). I modified original files so all errors are mine, not Igor's.
  - Many different performance optimizations (especially for RSA/DSA algorithms and enveloped signatures).
  - XPath Filter 2 and Alternative XPath Filter (not compiled by default, use --enable-altxpath configuration switch if you need this transform) support is added.
  - Custom network protocol handler support is added. It is similar to custom protocol handlers in LibXML2 but applied to binary files.
  - Separated XML Security Library RPM into xmlsec and xmlsec-devel (suggested by Devin Heitmueller).
- May 14, 2002
  I've checked in new code for plugging in custom input handlers (similar to ones that exist in LibXML2). The downside is that you have to use daily LibXML2 snapshot to compile daily XML Security Library snapshot.
- April 28, 2002
  XMLSec 0.0.5 released:
  - Big external and internal cleanup. Now the API looks much more consistent and I hope simple. I hope to declare API frozen in the next couple weeks. Meantime, all comments and suggestions are welcome!
  - Added symmetric key wrap (aes, des) support.
  - Added RIPEMD-160 support.
- April 19, 2002
  Minor release XMLSec 0.0.4 with main goal to fix broken RPM:
  - The RPM is recompiled using OpenSSL 0.9.6. The previous version was compiled with OpenSSL 0.9.7 but I got few complains that there are no RPMs for 0.9.7 yet. The downsides of using 0.9.6 are some functionality limitations for XML Encryption (no AES support, incorrect padding mode for DES, etc.). If you want to use XML Encryption it is better to compile the library from sources and use OpenSSL 0.9.7
  - The testDSig, testEnc and testKeys scripts merged into standalone "xmlsec" application.
  - A couple minor bugs fixed.
- April 17, 2002
  Installed xmlsec mailing list.
- April 16, 2002
  A lot of changes and time for new release XMLSec 0.0.3:
  - The first release that includes XML Encryption support! The bad news is that most of new features require OpenSSL 0.9.7 which is not officially released yet.
  - Options to enable/disable support for particular algorithms were added to the `./configure` script.
  - All transforms header files were consolidated in "transforms.h".
- April 6, 2002
  The RPM packages are now available.
- April 5, 2002
  Test suite updates and new minor release XML Security Library 0.0.2a.
  New interoperability tests were provided by Merlin Hughes. XML Security Library successfully passed all tests after small test program tweaking and adding workaround for OpenSSL CRL problem. These new tests are included into the distribution and previous Merlin's test suites are removed. Because of these changes I decided to generate a new package that also will include the Online XML Digital Signature Verifier code.
- April 3, 2002
  The Online XML Digital Signature Verifier is available! You can use this tool to verify your XML Digital Signatures from online Web form or using a simple Perl script. The idea was stolen from Manoj K. Srivastava.
- March 31, 2002
  Some major changes and a time for new release: XML Security Library 0.0.2 . Now XML Security Library supports all MUST/SHOULD/MAY features from XMLDSig standard!
  - Added X509 certificates and certificate chains support
  - The detailed signature generation/verification results are made available to the application
  - RetrievalMethod, Manifests and additional algorithms are added
  - The Transforms and KeyInfo code was significantly re-writen with a goal to separate it from XMLDSig logic for better re-usability (in XML Encryption, etc.)
- March 18, 2002
  - Fixed wrong way shift of the DSA digest result bug found by Philipp G�hring. This bug is critical and I have to do a new build.
  - Added "--with-pedantic" configuration option and fixed all but "unused variable" warnings (bug reported by Daniel Veillard).
- March 17, 2002
  The XML Security Library 0.0.1 is released and available for download! Please try it out and send me your comments/suggestions.
