EVP_MAC-Siphash

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_set_ctx_params(). Furthermore, the "size" parameter can be retrieved with EVP_MAC_get_ctx_params(), or with EVP_MAC_size(). The length of the "size" parameter should not exceed that of a size_t.

"key" (OSSL_MAC_PARAM_KEY) <octet string>
"size" (OSSL_MAC_PARAM_SIZE) <unsigned integer>
