Reverse engineering Samsung S6 framework

Hi,

I'm trying to reverse engineer the Samsung S6 framework with Android 5.1.1 to look at the KNOX features. I'm currently particularly interested in the ODE and other encryption schemes. I tried decompiling the services.odex and boot.oat, and I'm seeing references to com.sec.knox.container.util.KeyManagementUtil and com.sec.knox.container.util.EnterprisePartitionMan ager that has methods that pertain to key generation and container creation, but I don't see these classes in either services.odex or framework2.jar in boot.oat. Does anyone know where this class resides?

Thanks.
