PlayreadyDevice

class PlayreadyDevice

A provisioned PlayReady device — the contents of a .prd file.

A device is a certificate chain whose leaf attests to two key pairs: signingKey, which signs license challenges, and encryptionKey, to which the server encrypts content-key material. A v3 device also keeps the groupKey that issued the leaf, which is what lets it be reprovisioned.

A filesystem-safe name for this device, as manufacturer_model_slNNNN.

val securityLevel: Int

150, 2000 or 3000, read from the chain's leaf.
