 1. Provide `secret` with `psa_key_derivation_input_key()`, referencing a key that
    can be used for key derivation.
 1. Set the key attributes desired for the new derived key. We'll set
-   the `PSA_KEY_USAGE_ENCRYPT` parameter and the `PSA_ALG_CTR` algorithm for this
+   the `PSA_KEY_USAGE_ENCRYPT` usage flag and the `PSA_ALG_CTR` algorithm for this

 1. Derive the key by calling `psa_key_derivation_output_key()`.
 1. Clean up the key derivation context.
