7.2. The Cryp driver

This library is an implementation of the STM32F4 Cryp cryptographic HW accelerator.

It provide an abstraction of the Cryp device interactions through high level API in order to request (de)cryption of any data using one of the supported cryptographic algorithm of the hardware device.
