XMLTooling - Is it possible to not emit <ds:KeyInfo> in C++?

[Selhorst, Marcel]

Hi list,

I currently have an issue regarding the generation and emitting of the <ds:KeyInfo>-Object in the C++-Version of XMLTooling:
I am using OpenSAML to generate signed SAMLRequests including encrypted extensions. 
For privacy reasons I don't want to emit additional key information such as <ds:KeyName> and <ds:X509Data> 
(including the used certificate in <ds:X509Certificate and the SubjectName in <ds:X509SubjectName>), 
which is in C++ by default emitted within the signature as well as the encrypted extension.

In Java I managed to remove this by simply using the KeyInfoGeneratorFactory and setting setEmit* to 'false', similar to this:

	X509KeyInfoGeneratorFactory kiFactory = new X509KeyInfoGeneratorFactory();
	kiFactory.setEmitEntityCertificate(false);
	kiFactory.setEmitKeyNames(false);
	kiFactory.setEmitX509SubjectName(false);
	KeyInfo sigKeyInfo = 
		kiFactory.newInstance().generate(mySigCred);
	signature.setKeyInfo(sigKeyInfo);

However, I can't find a solution for this in C++.
Trying something like:

	KeyInfo* foo = KeyInfoBuilder::buildKeyInfo();
	mySignature->setKeyInfo(foo);
or
	mySignature->setKeyInfo(nullptr);

always includes the aforementioned key information...
Any clue how I can do this with C++?

Thanks in advance and best regards!
Marcel
