Gets the content key identifier of the MediaLicense.
Assembly: System.Windows (in System.Windows.dll)
Property ValueType: System.Guid
The content key identifier of the MediaLicense. If the MediaLicense instance represents a license, then this property returns the content key identifier of the license itself. If the class instance represents a license chain, then it is the content key identifier of the leaf license. For more information about license chains and leaf licenses, see Digital Rights Management (DRM). Since content also contains the key identifier for the key needed to decrypt the content, this value is used to pair a license with the content for decryption.
