| =head1 NAME |
| |
| EVP_MAC-CMAC - The CMAC EVP_MAC implementation |
| |
| =head1 DESCRIPTION |
| |
| Support for computing CMAC 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 "CMAC", "default=yes" |
| |
| =back |
| |
| =head2 Supported parameters |
| |
| The general description of these parameters can be found in |
| L<EVP_MAC(3)/PARAMETERS>. |
| |
| The following parameter can be set with EVP_MAC_CTX_set_params(): |
| |
| =over 4 |
| |
| =item B<OSSL_MAC_PARAM_KEY> ("key") <octet string> |
| |
| =item B<OSSL_MAC_PARAM_ENGINE> ("engine") <utf8 string> |
| |
| =item B<OSSL_MAC_PARAM_CIPHER> ("cipher") <utf8 string> |
| |
| =item B<OSSL_MAC_PARAM_PROPERTIES> ("properties") <utf8 string> |
| |
| =back |
| |
| The following parameters can be retrieved with |
| EVP_MAC_CTX_get_params(): |
| |
| =over 4 |
| |
| =item B<OSSL_MAC_PARAM_SIZE> ("size") <unsigned int> |
| |
| =back |
| |
| The "size" parameter can also be retrieved with with EVP_MAC_size(). |
