gnutls_mac_algorithm_t algorithm
the HMAC algorithm to use
const void * key
the key to be used for encryption
size_t keylen
the length of the key
Описание (Description)
This function will initialize an context that can be used to
produce a Message Authentication Code (MAC) of data. This will
effectively use the current crypto backend in use by gnutls or
the cryptographic accelerator in use.
Note that despite the name of this function, it can be used for
other MAC algorithms than HMAC.
