EVP_SIGNATURE-CMAC - The legacy EVP_PKEY MAC signature implementations
The algorithms described here have legacy support for creating MACs using
EVP_DigestSignInit(3) and related functions. This is not the preferred
way of creating MACs. Instead you should use the newer 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
EVP_MAC-HMAC(7), EVP_MAC-Siphash(7),
EVP_MAC-Poly1305(7) and 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.
