Maybe someone of you stumbled upon something usefull. Thanks in advance.

XMLSec (http://www.aleksey.com/xmlsec/), which is built on libxml2 (http://www.xmlsoft.org), supports both Signature and Encryption. You can find prebuilt Win32 DLLs at http://www.zlatkovic.com/libxml.en.html, and Delphi wrappers at http://sourceforge.net/projects/libxml2-pas.

Is there some serious competition known to it? I would like to evaluate a wide range of products to find the one most suitable for me.

Hi again, I evaluated the whole thing now and it works very well. The big drawback is, that it relies on LibXML which relies on IconV and IconV ist under GNU-License so I can't use it in proprietary software. :( Is there still hope or am I lost?

Then you are out of luck, unless you (or someone else) recompiles LibXML2 to turn off the iconv support (there is a flag for it).

Yes, it would take too much time for me I think especially staying up to date.

I've downloaded the libiconv 1.9.2 (The same version you find at zlatkovic) at GnuWin (on sourceforge) and it looks like it is licensed under the LGPL, the lesser general gnu public license which means that you can link against it even in proprietary software Actually the iconv.h file in the zlatkovic archive says: The GNU LIBICONV Library is free software; you can redistribute it and/or modify it under the terms of the GNU Library General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. So you are allowed to dynamically link that DLL, but if you apply changes *directly* *to* *the* *library*, you have to make them available in source to you customer (BTW: you have to provide the source code of th iconv library also available to you customer) I am not a lawyer, so please re-check with you law department (or hire a lawyer for this specific question) Best regards Andreas -- Andreas Tscharner andreas.tscharner (AT) metromec (DOT) ch ------------------------------------------------------------------------ Real coders don't comment their code.

I really hope for a typo in the second paragraph. ;) Otherwise it's still not usable, but thanks anyway for your comment.

I think I need to make myself clear... Yes GPL2 is not LGPL If you use GPL code, you have to license all your code that uses the GPL code as well under the GPL, even it is only linked dynamically (DLL) If you use LGPL code, you can license your code under whatever license you want as long as it is linked dynamically. If you make changes to the code that is LGPL, you have to license that specific code under the LGPL. For libiconv, which is LGPL: You can use it in your application without having to license you application under the LGPL. If you make bugfixes or changes to the libiconv code directly, this code has to be licensed under the LGPL Best regards Andreas -- Andreas Tscharner andreas.tscharner (AT) metromec (DOT) ch ------------------------------------------------------------------------ Real coders don't comment their code.
