NAME

6       gnutls_hmac_get_key_size - API function
7

SYNOPSIS

9       #include <gnutls/crypto.h>
10
11       unsigned gnutls_hmac_get_key_size(gnutls_mac_algorithm_t algorithm);
12

ARGUMENTS

14       gnutls_mac_algorithm_t algorithm
15                   the mac algorithm to use
16

DESCRIPTION

18       This  function will return the size of the key to be used with this al‐
19       gorithm. On the algorithms which may accept arbitrary  key  sizes,  the
20       returned size is the MAC key size used in the TLS protocol.
21

RETURNS

23       The key size or zero on error.
