@deftypefun {void} {gnutls_anti_replay_set_window} (gnutls_anti_replay_t @var{anti_replay}, unsigned int @var{window})

@var{anti_replay}: is a @code{gnutls_anti_replay_t}  type.

@var{window}: is the time window recording ClientHello, in milliseconds

Sets the time window used for ClientHello recording.  In order to

protect against replay attacks, the server records ClientHello

messages within this time period from the last update, and

considers it a replay when a ClientHello outside of the period; if

a ClientHello arrives within this period, the server checks the

database and detects duplicates.

For the details of the algorithm, see RFC 8446, section 8.2.
