| |
| EVP_SIGNATURE-HMAC, EVP_SIGNATURE-Siphash, EVP_SIGNATURE-Poly1305, |
| EVP_SIGNATURE-CMAC |
| - The legacy B<EVP_PKEY> MAC signature implementations |
| |
| =head1 DESCRIPTION |
| |
| The algorithms described here have legacy support for creating MACs using |
| L<EVP_DigestSignInit(3)> and related functions. This is not the preferred way of |
| creating MACs. Instead you should use the newer L<EVP_MAC_init(3)> functions. |
| This mechanism is provided for backwards compatibility with older versions of |
| OpenSSL. |
| |
| The same signature parameters can be set using EVP_PKEY_CTX_set_params() as can |
| be set via EVP_MAC_CTX_set_params() for the underlying EVP_MAC. See |
| L<EVP_MAC-HMAC(7)>, L<EVP_MAC-Siphash(7)>, L<EVP_MAC-Poly1305(7)> and |
| L<EVP_MAC-CMAC(7)> for details. |
| |
| See L<EVP_PKEY-HMAC(7)>, L<EVP_PKEY-Siphash(7)>, L<EVP_PKEY-Poly1305(7)> or |
| L<EVP_PKEY-CMAC(7)> for details about parameters that are supported during the |
| creation of an EVP_PKEY. |
