EVP_MAC-Siphash - The Siphash EVP_MAC implementation 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():

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. Sets the MAC key. Setting this parameter is identical to passing a key to EVP_MAC_init(3). Sets the MAC size. Specifies the number of rounds per message block. By default this is 2. Specifies the number of finalisation rounds. By default this is 4.
