/**
|
|
* \file psa/crypto_driver_common.h
|
|
* \brief Definitions for all PSA crypto drivers
|
|
*
|
|
* This file contains common definitions shared by all PSA crypto drivers.
|
|
* Do not include it directly: instead, include the header file(s) for
|
|
* the type(s) of driver that you are implementing. For example, if
|
|
* you are writing a dynamically registered driver for a secure element,
|
|
* include `psa/crypto_se_driver.h`.
|
|
*
|
|
* This file is part of the PSA Crypto Driver Model, containing functions for
|
|
* driver developers to implement to enable hardware to be called in a
|
|
* standardized way by a PSA Cryptographic API implementation. The functions
|
|
* comprising the driver model, which driver authors implement, are not
|
|
* intended to be called by application developers.
