NAME
EVP_MAC-Siphash - The Siphash EVP_MAC implementationDESCRIPTION
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.
