OP_mac_get_params() gets details of parameter values associated with the
provider algorithm and stores them in I<params>.

+OP_mac_set_ctx_params() sets mac parameters associated with the given
provider side mac context I<mctx> to I<params>.
Any parameter settings are additional to any that were previously set.

OP_mac_gettable_params(), OP_mac_gettable_ctx_params(), and
OP_mac_settable_ctx_params() all return constant B<OSSL_PARAM> arrays

Parameters currently recognised by built-in macs are as follows. Not all
=for comment We need to investigate if this is the right approach
-=item B<OSSL_MAC_PARAM_ALGORITHM> (utf8 string)
-
-Sets the name of the underlying algorithm to be used.
-It must name a suitable algorithm for the MAC that's being used.
-
-=item B<OSSL_MAC_PARAM_MD> (utf8 string)
-
-=item B<OSSL_MAC_PARAM_DIGEST> (utf8 string)
-
=item B<OSSL_MAC_PARAM_CIPHER> (utf8 string)
-These have the same meaning as B<OSSL_MAC_PARAM_ALGORITHM>, but specify
-the expected operation for the underlying algorithm.
-These are regarded as antiquated, but are kept for easier transition from
-legacy MAC implementations.
-
-=item B<OSSL_MAC_PARAM_ENGINE> (utf8 string)
+=item B<OSSL_MAC_PARAM_DIGEST> (utf8 string)
-Sets the name of an engine that implements the underlying algorithm.
-This must be given together with the algorithm naming parameter to be
-considered valid.
+Sets the name of the underlying cipher or digest to be used.
+It must name a suitable algorithm for the MAC that's being used.
=item B<OSSL_MAC_PARAM_PROPERTIES> (utf8 string)
This must be given together with the algorithm naming parameter to be
considered valid.
-Note that both this and B<OSSL_MAC_PARAM_ENGINE> can be given at the same time.
-If the underlying algorithm ends up being fetched from a provider, offered by
-and engine, or a built in legacy function depends on what is available.
-
=item B<OSSL_MAC_PARAM_SIZE> (int)
-=item B<OSSL_MAC_PARAM_DIGESTSIZE> (int)
-
-=item B<OSSL_MAC_PARAM_OUTLEN> (int)
+Can be used to get the resulting MAC size.
-All three names are considered the same.
-B<OSSL_MAC_PARAM_SIZE> and B<OSSL_MAC_PARAM_DIGESTSIZE> are considered
-antiquated, but are kept for easier transition from legacy MAC implementations.
+With some MAC algorithms, it can also be used to set the size that the
+resulting MAC should have.
+Allowable sizes are decided within each implementation.
