 * @mainpage OEMCrypto v16 Core Message Serialization library
 *
 * For Widevine Modular DRM, there are six message types between a server and
 * a client device: license request and response, provisioning request and
 * response, and renewal request and response.
 *
 * In OEMCrypto v15 and earlier, messages from the server were parsed by the
 * CDM layer above OEMCrypto; the CDM in turn gave OEMCrypto a collection of
 * pointers to protected data within the message. However, the pointers
 * themselves were not signed by the server.
 *
 * Starting from OEMCrypto v16, all fields used by OEMCrypto in each of these
 * messages have been identified in the document "Widevine Core Message
 * Serialization". These fields are called the core of the message. Core
 * message fields are (de)serialized using the ODK, a C library provided by
 * Widevine. OEMCrypto will parse and verify the core of the message with
 * help from the ODK.
 *
 * The ODK functions that parse code will fill out structs that have similar
 * formats to the function parameters of the OEMCrypto v15 functions being
 * replaced. The ODK will be provided in source code and it is Widevine's
 * intention that partners can build and link ODK with their implementation
 * of OEMCrypto with no or few code changes.
 *
 * OEMCrypto implementers shall build the ODK library as part of the Trusted
 * Application (TA) running in the TEE.  All memory and buffers used by the
 * ODK library shall be sanitized by the OEMCrypto implementer to prevent
 * modification by any process running the REE.
 *
 * See the documents
 * <a href="../odk">Widevine Core Message Serialization</a>
 * and
 * <a href="../../lic_duration_and_renewal">License Duration and Renewal</a>
 * for a detailed description of the ODK API. You can
 * find these documents in the widevine repository as
 * docs/Widevine_Core_Message_Serialization.pdf and

 * @param[in] nonce_values: pointer to the session's nonce data.
 * @param[in] device_id: a pointer to a buffer containing the device ID of the
 *       device. The ODK function will verify it matches that in the message.
