5 EVP_MAC-Poly1305 - The Poly1305 EVP_MAC implementation
9 Support for computing Poly1305 MACs through the B<EVP_MAC> API.
13 This implementation is identified with this name and properties, to be
14 used with EVP_MAC_fetch():
18 =item "Poly1305", "default=yes"
22 =head2 Supported parameters
24 The general description of these parameters can be found in
25 L<EVP_MAC(3)/PARAMETERS>.
27 The following parameter can be set with EVP_MAC_CTX_set_params():
31 =item B<OSSL_MAC_PARAM_KEY> ("key") <octet string>
35 The following parameters can be retrieved with
36 EVP_MAC_CTX_get_params():
40 =item B<OSSL_MAC_PARAM_SIZE> ("size") <unsigned integer>
44 The "size" parameter can also be retrieved with with EVP_MAC_size().
45 The length of the "size" parameter should not exceed that of an B<unsigned int>.
