Could you confirm which device, which RTD and which HSE firmware version you have?

There’s no problem in your configuration.

It works on my side. But one possible issue could be the length of tag (secondaryInputLength).

This can be found in function Crypto_Ipw_HmacVerify:

If redirection is disabled, it’s necessary to provide the length of tag in bits, not in bytes. Isn’t this the problem?
