This example is split into two parts: The first part is to encrypt DATA in CTR mode and compare between the encrypted data and expected encrypted data is done to check that the input data have been correctly encrypted. The Second part is to decrypt DATA in CTRs mode and compare between the decrypted data and expected decrypted data is done to check that the input data have been correctly decrypted. @note NIST vectors examples for AES CTR are taken from: "Recommendation for Block Cipher Modes of Operation, 2001 Edition" Available at: http://csrc.nist.gov/publications/nistpubs/800-38a/sp800-38a.pdf @par Directory contents - AES/AES128_CTR/main.c Main program @note The System Clock configuration are handled in the Cryptographic library Project template for each devices, and can be easily customized to your own configuration. @par Hardware and Software environment - This example runs on: - STM32F10x Connectivity line, High-Density, Medium-Density, XL-Density, High-Density Value line, Medium-Density Value line, Low-Density and Low-Density Value line Devices. - STM32L1xx Ultra Low Power Medium-Density Devices Devices. - STM32F2xx Devices. - STM32F40/1x Devices. - STM32F30x/31x Devices. - STM32F37x/38x Devices. @note - When using optimized STM32 Cryptographic library based on hardware Cryptographic peripheral DMA2 Stream 5 and DMA2 Stream 6 are reserved to perform data tranfer to/from Cryptographic block. - Cryptographic and DMA2 peripheral clocks are enabled with algorithm initialization. - User application should disable these clocks when no more encryption/decryption will be performed. - This example has been tested with STMicroelectronics STM3210B-EVAL (Medium-Density), STM3210E-EVAL (High-Density and XL-Density), STM3210C-EVAL (STM32F10x Connectivity-Line), STM32 Value line discovery kit (STM32F10x Medium-Density Value line), STM32100E-EVAL (High-Density Value line), STM3220G-EVAL, STM32L152-EVAL (STM32L1xx Ultra Low Power Medium-Density), STM32F4 discovery kit and STM32 20-21-45-46 G-EVAL evaluation boards and doesn't depend on external hardware on the evaluation boards. - This example has been tested with STMicroelectronics STM3210B-EVAL (Medium-Density), STM3210E-EVAL (High-Density and XL-Density), STM3210C-EVAL (STM32F10x Connectivity-Line), STM32 Value line discovery kit (STM32F10x Medium-Density Value line), STM32100E-EVAL (High-Density Value line), STM3220G-EVAL, STM32L152-EVAL (STM32L1xx Ultra Low Power Medium-Density), STM32F4 discovery kit, STM32 20-21-45-46 G-EVAL, STM32F373C-EVAL, STM32F3 Discovery kit and STM32F0 discovery Kit and doesn't depend on external hardware on the evaluation boards. @par How to use it?
