+=head1 NAME
+
+EVP_MAC-BLAKE2, EVP_MAC-BLAKE2BMAC, EVP_MAC-BLAKE2SMAC
+- The BLAKE2 EVP_MAC implementations
+
+=head1 DESCRIPTION
+
+Support for computing BLAKE2 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().
+
+=over 4
+
+=item B<OSSL_MAC_PARAM_KEY> ("key") <octet string>
+
+This may be at most 64 bytes for BLAKE2BMAC or 32 for BLAKE2SMAC and
+at least 1 byte in both cases.
+
+=item B<OSSL_MAC_PARAM_CUSTOM> ("custom") <octet string>
+
+This is an optional value of at most 16 bytes for BLAKE2BMAC or 8 for
+BLAKE2SMAC.
+It is empty by default.
+
+=item B<OSSL_MAC_PARAM_SALT> ("salt") <octet string>
+
+This is an optional value of at most 16 bytes for BLAKE2BMAC or 8 for
+BLAKE2SMAC.
+It is empty by default.
+
+=item B<OSSL_MAC_PARAM_SIZE> ("size") <size_t>
+
+When set, this can be any number between between 1 and 32 for
+EVP_MAC_BLAKE2S or 64 for EVP_MAC_BLAKE2B.
+It is 32 and 64 respectively by default.
