Change signature tag name ds:Signature to Authsignature

Question

Hello,
I need to change the XML signature tag name from : *<ds:Signature> to <Authsignature>*
<ds:Signature> to <Authsignature>using code like :
XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM");
Reference ref = fac.newReference("", fac.newDigestMethod(DigestMethod.SHA256, null));
SignedInfo si = fac.newSignedInfo ...
KeyStore ks = KeyStore.getInstance();
DOMSignContext dsc = new DOMSignContext (keyEntry.getPrivateKey(), doc.getDocumentElement());
XMLSignature signature = fac.newXMLSignature(si, null);
signature.sign(dsc);
And validate it after.
using code like :
XMLSignatureFactory xmlSignatureFactory = XMLSignatureFactory.getInstance();
DOMValidateContext domValidateContext = new DOMValidateContext(KeySelector.singletonKeySelector(publicKey, signatureElement);
XMLSignature xmlSignature = xmlSignatureFactory.unmarshalXMLSignature(domValidateContext);
boolean ok = xmlSignature.validate(domValidateContext);How i can do it ?
Anyway, thanks in advance for your help.
Best regards,
Kurusaki

hi smullan,
I need to change it because i work with german norm (protocol) and the name of authentification and identification signature of XML file is *<AuthSignature>* and it is mandatory
am I really stucked as I feared??
sorry to bother you again, I ve got one last question
I can see in the xmldsig norm that the signature of a file is applied only
to the content of the <signedinfo> tag
So, given the <authsignature> tag is not included in the signed part of the
file, logically I could change the <authsignature> tag in <signature>
without corrupting my signed file could nt I??
It seems like I m in a dead end, but maybe there's a solution right
in front of me that I could nt see?? I wish!
Anyway, thanks in advance for your help.
Best regards,
