* HKDF-Expand using HMAC-SHA-256.
*
* This key derivation algorithm uses the following inputs:
* - PSA_KEY_DERIVATION_INPUT_SECRET is the pseudoramdom key (PRK).
* - PSA_KEY_DERIVATION_INPUT_SECRET is the pseudorandom key (PRK).
* - PSA_KEY_DERIVATION_INPUT_INFO is the info string.
*
* The inputs are mandatory and must be passed in the order above.
