+
+EVP_MAC-KMAC, EVP_MAC-KMAC256, EVP_MAC-KMAC256
+- The KMAC EVP_MAC implementations
+
+=head1 DESCRIPTION
+
+Support for computing KMAC MACs through the B<EVP_MAC> API.
+
+=head2 Identity
+
+These implementations are identified with one of these names and
+properties, to be used with EVP_MAC_fetch():

+
+=head2 Supported parameters
+
+The general description of these parameters can be found in
+L<EVP_MAC(3)/PARAMETERS>.
+
+All these parameters can be set with EVP_MAC_CTX_set_params().
+Furthermore, the "size" parameter can be retrieved with
+EVP_MAC_CTX_get_params(), or with EVP_MAC_size().

+

+
+The "xof" parameter value is exptect to be 1 or 0. Use 1 to enable XOF
+mode. If XOF is enabled then the output len that is encoded as part of
+the input stream is set to zero.
