Hi,
You can use the following method in DSIGSignature class :
XERCES_CPP_NAMESPACE_QUALIFIER DOMElement *createBlankSignature(
XERCES_CPP_NAMESPACE_QUALIFIER DOMDocument *doc,
canonicalizationMethod cm = CANON_C14N_NOC,
signatureMethod sm = SIGNATURE_DSA,
hashMethod hm = HASH_SHA1
);
Since you only need a SHA1 HASH, pass the signatureMethod as SIGNATURE_NONE.
Br,
Raghu.
thanks Sean for your reply, i'm using the c++ lib and was looking for the
solution in the xml-securty-c.
So is there a way to do this using the c++ libs
thanks!!
