EVP_MAC_name() returns the name of the given MAC implementation.
+EVP_MAC_is_a() checks if the given I<mac> is an implementation of an
+algorithm that's identifiable with I<name>.
+
EVP_MAC_provider() returns the provider that holds the implementation
of the given I<mac>.
EVP_MAC_name() returns the name of the MAC, or NULL if NULL was
passed.
+EVP_MAC_is_a() returns 1 if the given method can be identified with
+the given name, otherwise 0.
+
EVP_MAC_provider() returns a pointer to the provider for the MAC, or
NULL on error.
