NAME
EVP_MAC-Siphash - The Siphash EVP_MAC implementation
DESCRIPTION
Header "DESCRIPTION" Support for computing Siphash MACs through the EVP_MAC API.
Identity
Subsection "Identity" This implementation is identified with this name and properties, to be
used with EVP_MAC_fetch():
"""SIPHASH"", ""provider=default""" 4
Item """SIPHASH"", ""provider=default""" "Supported parameters"
Subsection "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 \fBEVP_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>" 4
Item """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>" 4
Item """size"" (OSSL_MAC_PARAM_SIZE) <unsigned integer>" Sets the MAC size.
"""c-rounds"" (OSSL_MAC_PARAM_C_ROUNDS) <unsigned integer>" 4
Item """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>" 4
Item """d-rounds"" (OSSL_MAC_PARAM_D_ROUNDS) <unsigned integer>" Specifies the number of finalisation rounds. By default this is 4.
