RootKID = KeyObj.GenerateKeyID()
LeafKID = KeyObj.GenerateKeyID()
' Generate the content key for the leaf license.
KeyObj.Seed = LKSeed
KeyObj.KeyID = LeafKID
ContentKey = KeyObj.GenerateKey()
' Set values into the content header and sign it.
Set HeaderObj = Server.CreateObject("WMRMObjs.WMRMHeader")
