IWMRMHeaderSigning and AddDigitalSignatureObject |
|
|
Does anyone know how to use the AddDigitialSignatureObject method of the
IWMRMHeaderSigning interface? My company needs a method of resigning a
header after it has been modified and I was given a link to this page
http://msdn.microsoft.com/library/en-us/wmrm10/htm/iwmrmheadersigninginterface.asp?frame=true
as a possible way of doing so.
I'm not the developer that works with DRM. I was given this problem to
solve because no one else knows C++. I was going to create a simple program
to read the header of a WMA file, pass it into this method and hopefully
write it back to the WMA file. However, I don't know what DRM object
implements this interface. I also notice is says that this interface is not
Automation-compliant, so I'm not sure what that means to me.
Thank you for any help that can be provided.
