 EVP_PKEY_new_CMAC_key() works in the same way as EVP_PKEY_new_raw_private_key()
 except it is only for the B<EVP_PKEY_CMAC> algorithm type. In addition to the

 EVP_PKEY_new_mac_key() works in the same way as EVP_PKEY_new_raw_private_key().
 New applications should use EVP_PKEY_new_raw_private_key() instead.
