EVP_MAC-BLAKE2 - Online Linux Manual PageSection : 7ossl
Updated : 2023-03-21
Source : 3.0.8
Note : OpenSSL
NAMEEVP_MAC−BLAKE2, EVP_MAC−BLAKE2BMAC, EVP_MAC−BLAKE2SMAC ​− The BLAKE2 EVP_MAC implementations
DESCRIPTIONSupport for computing BLAKE2 MACs through the EVP_MAC API.
IdentityThese implementations are identified with one of these names and properties, to be used with EVP_MAC_fetch(): .IP """BLAKE2BMAC"", ""provider=default""" 4 .IP """BLAKE2SMAC"", ""provider=default""" 4
Supported parametersThe 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. Likewise, the "block-size" parameter can be retrieved with ​EVP_MAC_CTX_get_params(), or with EVP_MAC_CTX_get_block_size(). .IP """key"" (OSSL_MAC_PARAM_KEY) <octet string>" 4 Sets the MAC key. It may be at most 64 bytes for BLAKE2BMAC or 32 for BLAKE2SMAC and at least 1 byte in both cases. Setting this parameter is identical to passing a key to EVP_MAC_init (3). .IP """custom"" (OSSL_MAC_PARAM_CUSTOM) <octet string>" 4 Sets the custom value. It is an optional value of at most 16 bytes for BLAKE2BMAC or 8 for BLAKE2SMAC, and is empty by default. .IP """salt"" (OSSL_MAC_PARAM_SALT) <octet string>" 4 Sets the salt. It is an optional value of at most 16 bytes for BLAKE2BMAC or 8 for BLAKE2SMAC, and is empty by default. .IP """size"" (OSSL_MAC_PARAM_SIZE) <unsigned integer>" 4 Sets the MAC size. It can be any number between 1 and 32 for EVP_MAC_BLAKE2S or between 1 and 64 for EVP_MAC_BLAKE2B. It is 32 and 64 respectively by default. .IP """block-size"" (OSSL_MAC_PARAM_SIZE) <unsigned integer>" 4 Gets the MAC block size. By default, it is 64 for EVP_MAC_BLAKE2S and 128 for EVP_MAC_BLAKE2B.
