Porting to STM32 - what should hydro_random_init() do? about libhydrogen HOT 3 CLOSED

For anyone else who wants to use an STM32 with hardware RNG:
Copy the ESP32 version of hydro_random_init()
Use HAL_RNG_GenerateRandomNumber() instead of esp_random() to put random numbers in r.
Use HAL_Delay() instead of delay() - not sure there is a delay needed though.

Hi!

Unfortunately, I don't have a board with that microcontroller, but if it has a built-in hardware RNG, this is going to be easy.

All you need is define a hydro_random_init() function for that platform, that fills hydro_random_context.state.

See how it's done on other platforms, particularly on ESP32.
