5 EVP_MAC-Siphash - The SipHash EVP_MAC implementation
9 Support for computing SipHash 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 "SIPHASH", "provider=default"
23 =head2 Supported parameters
25 The general description of these parameters can be found in
26 L<EVP_MAC(3)/PARAMETERS>.
28 All these parameters can be set with EVP_MAC_CTX_set_params().
29 Furthermore, the "size" parameter can be retrieved with
30 EVP_MAC_CTX_get_params(), or with EVP_MAC_size().
31 The length of the "size" parameter should not exceed that of a B<size_t>.

37 =item "size" (B<OSSL_MAC_PARAM_SIZE>) <unsigned integer>
