I'm considering using an XML dsig for basic app licensing. The app is native windows code (no .net). I can easily use .net to create a dsig offline, but then I want to verify it in native c++. From what I've found so far MSXML V5 will do the job, but musn't be used and V6 removes support for dsigs.
So how can I easily verify an XML dsig produced by .net code in native C++?
