=item B<OSSL_KDF_PARAM_PROPERTIES> ("properties") <UTF8 string>
Some KDF implementations use other cryptographic algorithms, this parameter
sets what property query will be used to fetch the implementation.
=item B<OSSL_KDF_PARAM_MAC> ("mac") <UTF8 string>
Some KDF implementations use a MAC as an underlying computation
algorithm, this parameter sets what the MAC algorithm should be.
=item B<OSSL_KDF_PARAM_DIGEST> ("digest") <UTF8 string>
For MAC implementations that use a message digest as an underlying computation
algorithm, this parameter sets what the digest algorithm should be.
=item B<OSSL_MAC_PARAM_ENGINE> ("engine") <utf8string>
For KDF implementations that use an underlying computation MAC or
digest, these parameters set what the algorithm should be, and the
engine that implements the algorithm or the properties to fetch it
by if needed.
The value is always the name of the intended engine, algorithm,
or the properties.
Note that not all algorithms may support all possible underlying
implementations.
