@ -324,7 +324,7 @@ A key derivation driver has the following entry points:
* `"key_derivation_input_step"` (optional): provide an extra input for the key derivation. This entry point is only mandatory in drivers that support algorithms that have extra inputs. See [“Key derivation driver long inputs”](#key-derivation-driver-long-inputs).
* `"key_derivation_output_bytes"` (mandatory): derive cryptographic material and output it. See [“Key derivation driver outputs”](#key-derivation-driver-outputs).
* `"key_derivation_output_key"`, `"key_derivation_verify_bytes"`, `"key_derivation_verify_key"` (optional, opaque drivers only): derive key material which remains inside the same secure element. See [“Key derivation driver outputs”](#key-derivation-driver-outputs).
* `"key_derivation_set_capacity"` (mandatory for opaque drivers that implement `"key_derivation_output_bytes"` for “cooked”, i.e. non-raw-data key types): update the capacity policy on the operation. See [“Key derivation driver operation capacity”](#key-derivation-driver-operation-capacity).
* `"key_derivation_set_capacity"` (mandatory for opaque drivers that implement `"key_derivation_output_key"` for “cooked”, i.e. non-raw-data key types): update the capacity policy on the operation. See [“Key derivation driver operation capacity”](#key-derivation-driver-operation-capacity).
* `"key_derivation_abort"` (mandatory): always the last entry point to be called.
For naming purposes, here and in the following subsection, this specification takes the example of a driver with the prefix `"acme"` that implements the `"key_derivation"` entry point family with a capability that does not use the `"names"` property to declare different type and entry point names. Such a driver must implement the following type and functions, as well as the entry points listed above and described in the following subsections:
