@par Example Description
|
|
|
|
How to use the HASH peripheral to hash data with SHA-1 and MD5 algorithms.
|
|
|
|
For this example, DMA is not used for data transfer, the CPU is using HASH peripheral in
|
|
polling mode.
|
|
|
|
The SHA-1 message digest result is a 160 bit data and the MD5 message digest result
|
|
is a 128 bit data.
|
|
The expected HASH digests (for SHA1 and MD5) are already computed using an online
|
|
HASH tool. Those values are compared to those computed by the HASH peripheral.
|
|
|
|
In case there is a missmatch the red LED is turned ON.
|
|
In case the SHA1 digest is computed correctly the green LED (LED1) is turned ON.
|
|
In case the MD5 digest is computed correctly the blue LED (LED4) is turned ON.
|
|
|
|
|
|
@note The connection of the LCD reset pin to a dedicated GPIO PK7 instead of the STM32F469 NRST pin may cause residual display on LCD with applications/examples that do not require display.
|
|
The LCD clear can be ensured by hardware through the board's power off/power on or by software calling the BSP_LCD_Reset() function.

@par Hardware and Software environment
|
|
|
|
- This example runs on STM32F479xx devices.
|
|
|
|
- This example has been tested and validated with STM32479I-EVAL RevC board and can be
|
|
easily tailored to any other supported device and development board.
|
|
|
|
@par How to use it ?
|
|
|
|
In order to make the program work, you must do the following :
|
|
- Open your preferred toolchain
|
|
- Rebuild all files and load your image into target memory
|
|
- Run the example
