9Support for computing CMAC MACs through the B<EVP_MAC> API.

11=head2 Identity
12
13This implementation is identified with this name and properties, to be
14used with EVP_MAC_fetch():

24The general description of these parameters can be found in
fddb1847 25L<EVP_MAC(3)/PARAMETERS>.

27The following parameter can be set with EVP_MAC_CTX_set_params():
28
29=over 4

0c452a51 31=item "key" (B<OSSL_MAC_PARAM_KEY>) <octet string>

0c452a51 33=item "cipher" (B<OSSL_MAC_PARAM_CIPHER>) <UTF8 string>

39The following parameters can be retrieved with
40EVP_MAC_CTX_get_params():
41
42=over 4
43
0c452a51 44=item "size" (B<OSSL_MAC_PARAM_SIZE>) <unsigned integer>
e592dbde

47
48The "size" parameter can also be retrieved with with EVP_MAC_size().
f49a65d0 49The length of the "size" parameter is equal to that of an B<unsigned int>.
