NAME

       gnutls_hmac_get_key_size - API function

SYNOPSIS

       #include <gnutls/crypto.h>

       unsigned gnutls_hmac_get_key_size(gnutls_mac_algorithm_t algorithm);

ARGUMENTS

       gnutls_mac_algorithm_t algorithm
                   the mac algorithm to use

DESCRIPTION

       This  function  will  return  the  size  of the key to be used with this algorithm. On the
       algorithms which may accept arbitrary key sizes, the returned size is  the  MAC  key  size
       used in the TLS protocol.

RETURNS

       The key size or zero on error.
