* For example, `PSA_ALG_HKDF(PSA_ALG_SHA256)` is HKDF using HMAC-SHA-256.

* This key derivation algorithm uses the following inputs:
* - #PSA_KDF_STEP_SALT is the salt used in the "extract" step.
* - #PSA_KEY_DERIVATION_INPUT_SALT is the salt used in the "extract" step.
* It is optional; if omitted, the derivation uses an empty salt.
* - #PSA_KDF_STEP_SECRET is the secret key used in the "extract" step.
* - #PSA_KDF_STEP_INFO is the info string used in the "expand" step.
