<h1 id="purpose">Purpose</h1>
<p>The hardware abstraction layer (HAL) provides low level drivers and the hardware interfacing methods to interact with upper layer (application, libraries and stacks). It includes a complete set of ready-to-use APIs, that are feature-oriented instead of IP-Oriented to simplify user application development.</p>

<ul>
<li>HAL CRYP driver has been redesigned with new API’s, to bypass limitations on data Encryption/Decryption management present with previous HAL CRYP driver version.</li>
<li>The new HAL CRYP driver is the recommended version. It is located as usual in Drivers/STM32F7xx_HAL_Driver/Src and Drivers/STM32f7xx_HAL_Driver/Inc folders. It can be enabled through switch HAL_CRYP_MODULE_ENABLED in stm32f7xx_hal_conf.h</li>
