| =head1 NAME |
| |
| EVP_MAC-Siphash - The SipHash EVP_MAC implementation |
| |
| =head1 DESCRIPTION |
| |
| Support for computing SipHash MACs through the B<EVP_MAC> API. |
| |
| =head2 Identity |
| |
| This implementation is identified with this name and properties, to be |
| used with EVP_MAC_fetch(): |
| |
| =over 4 |
| |
| =item "SIPHASH", "provider=default" |
| |
| =back |
| |
| |
| =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 length of the "size" parameter should not exceed that of a B<size_t>. |
| |

| =item "key" (B<OSSL_MAC_PARAM_KEY>) <octet string> |
| |
| =item "size" (B<OSSL_MAC_PARAM_SIZE>) <unsigned integer> |
