Hey All,
We are working on a product based on the nRF5340. We will be using symmetric key authentication(HMAC) and was wondering the best way to go about provisioning the secret key.
I've seen that there's a psa_set_key_lifetime
api to set the key as persistent. I also saw the TF-M example where the KMU is used and the secret key is provisioned to one of the slots in the KMU.
We are building the project as a _ns application. Was looking for some advice on my options for this.
