my point is ... let's suppose that i get the following XML document as input
<doc>
<element id="123">
</signature>
</element>
</doc>
so if i have to create an enveloped signature for the element "element"
the result should be the following rigth?
<doc>
<element id="123">
<signature>
.....
<reference URI="#123">
</signature>
</element>
</doc>
Yes.
Using the java API (javax.xml.crypto.dsig) i will have to construct the
output xml document showed above with the signature ??? let say using a
DocumentBuilderFactory instance and the createElement method or there
is a transparent way for the programmer to put the signature element
inside the element "element"?? just using the Reference, SignedInfo and
the rest of the traditional classes...?
You do have to specify where you want the Signature element to be
located. The implementation will do the rest of the work of creating the
Signature element and inserting it in the document. Have you looked at
the example (also in the XMLSec download) of creating an enveloped
signature?
