stm32f4xx_cryp_aes.c File Reference

This file provides high level functions to encrypt and decrypt an input message using AES in ECB/CBC/CTR/GCM/CCM modes. It uses the stm32f4xx_cryp.c/.h drivers to access the STM32F4xx CRYP peripheral. AES-ECB/CBC/CTR/GCM/CCM modes are available on STM32F437x Devices. For STM32F41xx Devices, only AES-ECB/CBC/CTR modes are available. More...

Detailed Description

This file provides high level functions to encrypt and decrypt an input message using AES in ECB/CBC/CTR/GCM/CCM modes. It uses the stm32f4xx_cryp.c/.h drivers to access the STM32F4xx CRYP peripheral. AES-ECB/CBC/CTR/GCM/CCM modes are available on STM32F437x Devices. For STM32F41xx Devices, only AES-ECB/CBC/CTR modes are available.
