There is a vendor specific command to read the NVP of the device,
including the KAS. The trick is that the data is randomly
scrambled using a so-called para_noise array of random values.
There seems to be a problem when retrieving large entries (>1000
bytes typically) which causes sg_pt do behave strangely.

This tool can send vendor specific scsi commands to sony nwz
players such as getting serial number, model id, device info,
and others. It can potentially be used to get some private keys
stored on the device but probably not the KAS used to encrypt
firmware upgrades images(UPG).

This tool is specific to the em1/mp200 sony based players. In
deals with raw emmc images (which is possible but hard to get).
This tool is also useful as a documentation of the underlying
emmc format used for a future port.
