I am Missing the Option Security>RNG in my the .ioc tool. Does the F446RE does not have a RNG?
i experience identical problems to Implementation of ECC on STM32f446 (Page 1) — wolfSSL — wolfSSL - Embedded SSL Library

Well, this could be a copy'n'paste error, for which I would like to apologise. However, only the functions and parameters in the data sheet are relevant and guaranteed.

For my L452RE it looks like this:

Correct, in contrast to the STM32L452RE, the STM32F446 does not contain an RNG.
Does it answer your question?

ok thank you. do you have any instuctions on how to use wolfssl without a rng. I am struggling to get rsa encryption to run. Thank you for your time.

Apart from switching to an STM32 with RNG, no.
There are methods of generating a little randomness with a PRNG, by reading in the chip temperature or other simple approaches, but this is far away from a certified TRNG and may even be enough for a dice, but not for current encryption techniques.

i have the same problem did you found the solution ?

@fm1As mentioned before: choose an STM32 providing an RNG. If you have special requirements, you should create a new thread.
