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