[xmlsec] What can Xmlsec do for me?

[Mike Fudd]

Hello Mailinglist,

I want to develop a file format based on XML. Some parts of the file must be 
encrypted. A signature should be attached to warn the user that the file was 
externly changed and may not work with our application.

In the internet I have searched for an XML parser with encryption/signatures 
and found Xmlsec. But what doese Xmlsec+Libxml2 for me?
1. There is an Xml file with encrypted parts. Who doese the enc- decryption? 
Xmlsec? The only thing I have to implement is a secure place for the keys. 
Right?

2. Who doese the signatur thing? Who creates it, who checks it? Are this 
tasks automated within Xmlsec?

3. Libxml is a validating parser. With encryption and signature features are 
comming a lot of extra XML elements. (According to the standard how enc and 
sig must be implemented). Must I put this elements into the schema? If yes, 
is there a schema creating program that doese this work for me? Altova 
Xml-Spy doesnt.


Best wishes

Mike
