[xmlsec] xmlsec executable and examples

[Marius Kjeldahl]

Since xmlsec comes with an executable, does anybody have any simple 
examples that show how it all fits together?

Specifically, I'm trying to sign a small simple xml document, but xmlsec 
complains about missing signature sections.

E.g., take an xml file (test.xml) containing:

<SomeTest>
   <Message>
     <Somedata.test>Hello</Somedata.test>
   </Message>
</SomeTest>

If I try:

xmlsec sign test.xml

I get the following:

Error: failed to find Signature node
Error: operation failed

If I just try to add an empty Signature tag, it still does not work.

<SomeTest>
   <Message>
     <Somedata.test>Hello</Somedata.test>
   </Message>
   <Signature>
   </Signature>
</SomeTest>

I would like to fully understand how everything works together and what 
results to expect before I start digging into the API.

Does anybody have any examples of signing/encrypting using the command 
line tool that comes with xmlsec?

Thanks,
