bug: 12228689 If the device ID returned from OEMCrypto_GetDeviceUniqueId is not NULL terminated in the OEM code, trailing garbage characters may be included in the license request's client_identification field, which could be rejected by the server's utf8 parser if they are invalid characters, causing a license request failure. The code for CryptoSession::GetDeviceUniqueId should use the updated id_length from OEMCrypto_GetDeviceUniqueId to adjust the length of the *device_id string before returning the result to the caller.
