pkcs7

Hi!

I am struggling with the following scenario:

an XML-message is created client-side and digitally signed using mozilla's window.crypto.signText. After signing, the message and the signature are transmitted via a webservice (.net) to the server. Everything is fine until this point.
on the server, the XML shall be included in another XML-document, which is publicly accessible. The signature should be published as well in order to grant non-repudiation.

Q: Is there a smooth option to convert the detached Pkcs#7 into XML-DSIG (e.g. functionality within the .net framework)?

Q2: Or is it possible to create the XML-DSIG already client-side without using external plugins?

Tnx for your help!
