NAME

6       EVP_MAC-Siphash - The Siphash EVP_MAC implementation
7

DESCRIPTION

9       Support for computing Siphash MACs through the EVP_MAC API.
10
11   Identity
12       This implementation is identified with this name and properties, to be
13       used with EVP_MAC_fetch():
14
15       "SIPHASH", "provider=default"
16
17   Supported parameters
18       The general description of these parameters can be found in
19       "PARAMETERS" in EVP_MAC(3).
20
21       All these parameters can be set with EVP_MAC_CTX_set_params().
22       Furthermore, the "size" parameter can be retrieved with
23       EVP_MAC_CTX_get_params(), or with EVP_MAC_CTX_get_mac_size().  The
24       length of the "size" parameter should not exceed that of a size_t.
25
26       "key" (OSSL_MAC_PARAM_KEY) <octet string>
27           Sets the MAC key.  Setting this parameter is identical to passing a
28           key to EVP_MAC_init(3).
29
30       "size" (OSSL_MAC_PARAM_SIZE) <unsigned integer>
31           Sets the MAC size.
32
33       "c-rounds" (OSSL_MAC_PARAM_C_ROUNDS) <unsigned integer>
34           Specifies the number of rounds per message block.  By default this
35           is 2.
36
37       "d-rounds" (OSSL_MAC_PARAM_D_ROUNDS) <unsigned integer>
38           Specifies the number of finalisation rounds.  By default this is 4.
