+ *
+ * Valid values for OEMCrypto_BCCType are:
+ *
+ * OEMCrypto_CBOR means the device has a boot certificate chain of CBOR type,
+ * which shall follow the IETF CBOR Web Token (CWT) specification, and the CBOR
+ * Object Signing and Encryption (COSE) specification. Android requires CBOR.
+ * OEMCrypto_X509 means the device has a boot certificate chain of X509 type.
+ * Please work with your Widevine Partner Engineer if you plan to support X509.
