NAME

EVP_MAC-Siphash - The Siphash EVP_MAC implementation

DESCRIPTION

Support for computing Siphash MACs through the EVP_MAC API.

Identity

This implementation is identified with this name and properties, to be used with EVP_MAC_fetch():

"SIPHASH", "provider=default"

Supported parameters

The general description of these parameters can be found in ``PARAMETERS'' in EVP_MAC(3).

All these parameters can be set with EVP_MAC_CTX_set_params(). Furthermore, the ``size'' parameter can be retrieved with EVP_MAC_CTX_get_params(), or with EVP_MAC_CTX_get_mac_size(). The length of the ``size'' parameter should not exceed that of a size_t.

"key" (OSSL_MAC_PARAM_KEY) <octet string>: Sets the MAC key. Setting this parameter is identical to passing a key to EVP_MAC_init(3).
"size" (OSSL_MAC_PARAM_SIZE) <unsigned integer>: Sets the MAC size.
"c-rounds" (OSSL_MAC_PARAM_C_ROUNDS) <unsigned integer>: Specifies the number of rounds per message block. By default this is 2.
"d-rounds" (OSSL_MAC_PARAM_D_ROUNDS) <unsigned integer>: Specifies the number of finalisation rounds. By default this is 4.
