Hello Mailinglist,

I want to create a new file format (XML) for our application. The file format should have encrypted sections. The examples encrypt1.c, encrypt2.c and encrypt3.c are showing how to encrypt a whole existing XML. That are my problems:

1. The writer example of Libxml2 (testWriter.c) shows how to write XML tags directly to a file or into the RAM. Is it possible to use XMLSec to encrypt the XML file in the RAM? Because the plain text should never be written to harddisk. Is an example available?

2. How can I encrypt only some parts of an XML file? Is there a way to use the LibXml2 write commands through the XmlSec Api? (There is a LibXml2 function xmlTextWriterStartElement, than XmlSec could provide a function xmlTextWriterStartElementSec that saves the next element only encrypted to HD and all necessary encryption elemens like EncryptionMethod, KeyInfo, ... with them.)


Regards

Mike
