NAME

6       EVP_SIGNATURE-HMAC, EVP_SIGNATURE-Siphash, EVP_SIGNATURE-Poly1305,
7       EVP_SIGNATURE-CMAC - The legacy EVP_PKEY MAC signature implementations
8

DESCRIPTION

10       The algorithms described here have legacy support for creating MACs
11       using EVP_DigestSignInit(3) and related functions. This is not the
12       preferred way of creating MACs. Instead you should use the newer
13       EVP_MAC_init(3) functions.  This mechanism is provided for backwards
14       compatibility with older versions of OpenSSL.
15
16       The same signature parameters can be set using
17       EVP_PKEY_CTX_set_params() as can be set via EVP_MAC_CTX_set_params()
18       for the underlying EVP_MAC. See EVP_MAC-HMAC(7), EVP_MAC-Siphash(7),
19       EVP_MAC-Poly1305(7) and EVP_MAC-CMAC(7) for details.

21        See L<EVP_PKEY-HMAC(7)>, L<EVP_PKEY-Siphash(7)>, L<EVP_PKEY-Poly1305(7)> or
22        L<EVP_PKEY-CMAC(7)> for details about parameters that are supported during the
23        creation of an EVP_PKEY.
